A usually small, slow-growing neoplasm composed of islands of rounded, oxyphilic, or spindle-shaped cells of medium size, with moderately small vesicular nuclei, and covered by intact mucosa with a yellow cut surface. The tumor can occur anywhere in the gastrointestinal tract (and in the lungs and other sites); approximately 90% arise in the appendix. It is now established that these tumors are of neuroendocrine origin and derive from a primitive stem cell. (From Stedman, 25th ed & Holland et al., Cancer Medicine, 3d ed, p1182)
A symptom complex associated with CARCINOID TUMOR and characterized by attacks of severe flushing of the skin, diarrheal watery stools, bronchoconstriction, sudden drops in blood pressure, edema, and ascites. The carcinoid tumors are usually located in the gastrointestinal tract and metastasize to the liver. Symptoms are caused by tumor secretion of serotonin, prostaglandins, and other biologically active substances. Cardiac manifestations constitute CARCINOID HEART DISEASE. (Dorland, 27th ed; Stedman, 25th ed)
Cardiac manifestation of gastrointestinal CARCINOID TUMOR that metastasizes to the liver. Substances secreted by the tumor cells, including SEROTONIN, promote fibrous plaque formation in ENDOCARDIUM and its underlying layers. These deposits cause distortion of the TRICUSPID VALVE and the PULMONARY VALVE eventually leading to STENOSIS and valve regurgitation.

The resulting clinical signs include HYPERPARATHYROIDISM; HYPERCALCEMIA; HYPERPROLACTINEMIA; CUSHING DISEASE; GASTRINOMA; and ZOLLINGER-ELLISON SYNDROME. This disease is due to loss-of-function of the MEN1 gene, a tumor suppressor gene (GENES, TUMOR SUPPRESSOR) on CHROMOSOME 11 (Locus: 11q13).
A biochemical messenger and regulator, synthesized from the essential amino acid L-TRYPTOPHAN. In humans it is found primarily in the central nervous system, gastrointestinal tract, and blood platelets. Serotonin mediates several important physiological functions including neurotransmission, gastrointestinal motility, hemostasis, and cardiovascular integrity. Multiple receptor families (RECEPTORS, SEROTONIN) explain the broad physiological actions and distribution of this biochemical mediator.
A general term collectively applied to tumors associated with the APUD CELLS series, irrespective of their specific identification.

Mutations and allelic deletions of the MEN1 gene are associated with a subset of sporadic endocrine pancreatic and neuroendocrine tumors and not restricted to foregut neoplasms. (1/854)

Endocrine pancreatic tumors (EPT) and neuroendocrine tumors (NET) occur sporadically and rarely in association with multiple endocrine neoplasia type 1 (MEN1). We analyzed the frequency of allelic deletions and mutations of the recently identified MEN1 gene in 53 sporadic tumors including 30 EPT and 23 NET (carcinoids) of different locations and types. Allelic deletion of the MEN1 locus was identified in 18/49 (36.7%) tumors (13/30, 43.3% in EPT and 5/19, 26.3% in NET) and mutations of the MEN1 gene were present in 8/52 (15.3%) tumors (4/30 (13.3%) EPT and 4/22 (18.1%) NET). The somatic mutations were clustered in the 5' region of the coding sequence and most frequently encompassed missense mutations. All tumors with mutations exhibited a loss of the other allele and a wild-type sequence of the MEN1 gene in nontumorous DNA. In one additional patient with a NET of the lung and no clinical signs or history of MEN1, a 5178-9G-->A splice donor site mutation in intron 4 was identified in both the tumor and blood DNA, indicating the presence of a thus far unknown MEN1 syndrome. In most tumor groups the frequency of allelic deletions at 11q13 was 2 to 3 times higher than the frequency of identified MEN1 gene mutations. Some tumor types, including rare forms of EPT and NET of the duodenum and small intestine, exhibited mutations more frequently than other types. Furthermore, somatic mutations were not restricted to foregut tumors but were also detectable in a midgut tumor (15.2% versus 16.6%). Our data indicate that somatic MEN1 gene mutations contribute to a subset of sporadic EPT and NET, including midgut tumors. Because the frequency of mutations varies significantly among the investigated tumor subgroups and allelic deletions are 2 to 3 times more frequently observed, factors other than MEN1 gene inactivation, including other tumor-suppressor genes on 11q13, may also be involved in the tumorigenesis of these neoplasms.  (+info)

Carcinoids of the common bile duct: a case report and literature review. (2/854)

Carcinoids of the extrahepatic bile ducts and particularly the common bile duct are extremely rare. A 65-year-old woman presented with obstructive jaundice. Laboratory and imaging studies gave results that were consistent with an obstructing lesion in the common bile duct. In this case, a stent was inserted initially to decompress the bile ducts. Subsequently a laparotomy and pancreaticoduodenectomy were performed and a tissue diagnosis of carcinoid of the common bile duct was made. The patient was well with no evidence of recurrence 17 months postoperatively. The authors believe this is the 19th reported case of an extrahepatic bile duct carcinoid.  (+info)

Primary hepatic carcinoid in a renal transplant patient. (3/854)

There seems to be a world-wide increase in the incidence of tumors among immunosuppressed patients. Of 1350 renal allografts transplanted in the past 23 years at the Department of Transplantation and Surgery, 56 cases were malignant tumors. The case of a 58-year-old female patient is reported, with disseminated primary carcinoid in the liver detected 86 days after renal transplantation. According to the literature only 39 patients with primary liver carcinoids have been reported until 1997, but this is the first where the carcinoid developed in an immunosuppressed patient. The rapid progression of the carcinoid could be associated with the immunosuppression.  (+info)

Octreotide acetate long-acting formulation versus open-label subcutaneous octreotide acetate in malignant carcinoid syndrome. (4/854)

PURPOSE: Subcutaneous (SC) octreotide acetate effectively relieves the diarrhea and flushing associated with carcinoid syndrome but requires long-term multiple injections daily. A microencapsulated long-acting formulation (LAR) of octreotide acetate has been developed for once-monthly intramuscular dosing. PATIENTS AND METHODS: A randomized trial compared double-blinded octreotide LAR at 10, 20, and 30 mg every 4 weeks with open-label SC octreotide every 8 hours for the treatment of carcinoid syndrome. Seventy-nine patients controlled with treatment of SC octreotide 0.3 to 0.9 mg/d whose symptoms returned during a washout period and who returned for at least the week 20 evaluation constituted the efficacy-assessable population. RESULTS: Complete or partial treatment success was comparable in each of the four arms of the study (SC, 58.3%; 10 mg, 66.7%; 20 mg, 71.4%; 30 mg, 61.9%; P> or =.72 for all pairwise comparisons). Control of stool frequency was similar in all treatment groups. Flushing episodes were best controlled in the 20-mg LAR and SC groups; the 10-mg LAR treatment was least effective in the control of flushing. Treatment was well tolerated by patients in all four groups. CONCLUSION: Once octreotide steady-state concentrations are achieved, octreotide LAR controls the symptoms of carcinoid syndrome at least as well as SC octreotide. A starting dose of 20 mg of octreotide LAR is recommended. Supplemental SC octreotide is needed for approximately 2 weeks after initiation of octreotide LAR treatment. Occasional rescue SC injections may be required for possibly 2 to 3 months until steady-state octreotide levels from the LAR formulation are achieved.  (+info)

Primary carcinoid tumor of the testis: immunohistochemical, ultrastructural and DNA flow cytometric study of two cases. (5/854)

Primary testicular carcinoid tumor, occupying 0.23% of testicular neoplasm, is a rare and indolent neoplasm with the potential for distant metastasis. We present two cases of primary pure carcinoid tumor of the testis. Both patients were 36 years old. Physical examination revealed testicular mass with and without tenderness. The preoperative serum levels of beta-human chorionic gonadotropin and alpha-fetoprotein were normal and neither patient had carcinoid syndrome. The tumors measured 7.5x6x4 cm and 5.5x5x4 cm in size. Histologically, immunohistochemically and ultrastructurally, the tumors showed typical features of the carcinoid tumor. Case 1 showed extensive tumor necrosis and vascular invasion. DNA flow cytometric analysis showed aneuploidy with DNA index of 1.47 and S+G2M of 14.0% in case 1 and tetraploidy with DNA index of 1.96 and S+G2M of 22.1% in case 2. Both patients have been well without any signs of metastasis after operation for 24 months in case 1 and for 16 months in case 2.  (+info)

Library of sequence-specific radioimmunoassays for human chromogranin A. (6/854)

BACKGROUND: Human chromogranin A (CgA) is an acidic protein widely expressed in neuroendocrine tissue and tumors. The extensive tissue- and tumor-specific cleavages of CgA at basic cleavage sites produce multiple peptides. METHODS: We have developed a library of RIAs specific for different epitopes, including the NH2 and COOH termini and three sequences adjacent to dibasic sites in the remaining part of CgA. RESULTS: The antisera raised against CgA(210-222) and CgA(340-348) required a free NH2 terminus for binding. All antisera displayed high titers, high indexes of heterogeneity ( approximately 1.0), and high binding affinities (Keff0 approximately 0.1 x 10(12) to 1.0 x 10(12) L/mol), implying that the RIAs were monospecific and sensitive. The concentration of CgA in different tissues varied with the assay used. Hence, in a carcinoid tumor the concentration varied from 0.5 to 34.0 nmol/g tissue depending on the specificity of the CgA assay. The lowest concentration in all tumors was measured with the assay specific for the NH2 terminus of CgA. This is consistent with the relatively low concentrations measured in plasma from carcinoid tumor patients by the N-terminal assay, whereas the assays using antisera raised against CgA(210-222) and CgA(340-348) measured increased concentrations. CONCLUSION: Only some CgA assays appear useful for diagnosis of neuroendocrine tumors, but the entire library is valuable for studies of the expression and processing of human CgA.  (+info)

Review article: current status of gastrointestinal carcinoids. (7/854)

Carcinoid tumours are enigmatic, slow growing malignancies which occur most frequently (74%) in the gastrointestinal tract. In recent years, it has become apparent that the term 'carcinoid' represents a wide spectrum of different neoplasms originating from a variety of different neuroendocrine cell types. Carcinoid lesions are usually identified histologically by their affinity for silver salts, by general neuroendocrine markers, or more specifically by immunocytochemistry using antibodies against their specific cellular products. Within the gut, the most frequent sites are the small bowel (29%), the appendix (19%) and rectum (13%). Clinical manifestations are often vague or absent. Nevertheless, in approximately 10% of patients the tumours secrete bioactive mediators which may engender various elements of characteristic carcinoid syndrome. In many instances the neoplasms are detected incidentally at the time of surgery for other gastrointestinal disorders. The tendency for metastatic spread correlates with tumour size, and is substantially higher in lesions larger than 2.0 cm. An association with noncarcinoid neoplasms is ascribed in 8-17% of lesions. Treatment consists of radical surgical excision of the tumour, although gastric (type I and II) and rectal carcinoids may be managed with local excision. Overall 5-year survival is excellent for carcinoids of the appendix (86%) and rectum (72%), whereas small intestinal (55%), gastric (49%) and colonic carcinoids (42%) exhibit a far worse prognosis.  (+info)

Clinical symptoms, hormone profiles, treatment, and prognosis in patients with gastric carcinoids. (8/854)

BACKGROUND: Type 1 gastric carcinoids are associated with hypergastrinaemia and chronic atrophic gastritis, type 2 occur in patients with multiple endocrine neoplasia type 1 combined with Zollinger-Ellison syndrome, and type 3 lack any relation to hypergastrinaemia. Type 1 tumours are usually benign whereas type 3 are highly malignant. AIMS: To identify possible tumour markers in patients with gastric carcinoids. PATIENTS/METHOD: Nine patients with type 1, one with type 2, and five with type 3 were evaluated with regard to symptoms, hormone profile, and prognosis. RESULTS: Plasma chromogranin A was increased in all patients but was higher (p < 0.01) in those with type 3 than those with type 1 carcinoids. All patients with type 3 carcinoids died from metastatic disease, but none of the type 1 patients died as a result of their tumours. One type 1 patient with a solitary liver metastasis received interferon alpha and octreotide treatment. Nine months later, the metastasis was no longer detectable. She is still alive eight years after diagnosis, without recurrent disease. This represents the only reported case of foregut carcinoid with an unresectable liver metastasis that seems to be have been cured by biotherapy. CONCLUSIONS: Plasma chromogranin A appears to be a valuable tumour marker for all types of gastric carcinoid. Combination therapy with interferon alpha and octreotide may be beneficial in patients with metastasising type 1 gastric carcinoids.  (+info)

These tumors can manifest as central carcinoid tumors, pulmonary carcinoid tumorlets, or peripheral carcinoid tumors. Occasionally, the peripheral carcinoid tumors produce corticotropin and result in Cushings syndrome. Herein we report the first case of Cushings syndrome associated with a peripheral pulmonary carcinoid tumor that was excised by video-assisted thoracoscopy. After excision, the patient had complete remission. Video-assisted thoracoscopy may be ideal for resecting a ...
Carcinoid tumors alone represent 1% to 2% of all lung tumors and 25% of all carcinoid tumors [1,4,5]. Most patients with these tumors have mean age of 46 years [6]. Carcinoid tumors are a type of neuroendocrine tumors which usually involve the upper airways and clinical manifestations of carcinoid include persistent cough, hemoptysis, obstructive pneumonitis, dyspnoea and atelectasis [7,8]. These symptoms however can also be present in a patient with pulmonary tuberculosis [9]. Patients with classic carcinoid syndrome may have intermittent attacks of dyspnoea, flushing and cyanosis [10]. Lymph node metastasis could be a feature of atypical carcinoid tumor [11,12].. Bronchopulmonary carcinoid tumors are relatively uncommon neoplasms and typically benign and slow growing. However, more aggressive subtypes may develop early nodal and distant metastases [13]. Pulmonary neuroendocrine tumors comprise 20% of all lung cancers [14]. They are separated into 4 subgroups: typical carcinoid tumor, atypical ...

This review was performed to identify the optimal treatment strategy for pulmonary carcinoid, with a particular focus on the feasibility and outcome of parenchyma sparing techniques versus surgical resection. A systematic review of the literature was carried out using MEDLINE, Embase and the Cochrane databases, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis ...
A 49-year-old man was admitted to our hospital complaining of a large hepatic tumor with edema in the lower extremities. The patient had suffered from hypertension and bronchial asthma in his twenties and from cutaneous flushing in the face in his thirties. Echocardiography revealed tricuspid valve regurgitation and marked dilatation of the right ventricle. In an exploratory laparotomy, a 15 cm-size hepatic tumor was located in the right lobe with multiple satellite lesions in both lobes of the liver. Peritoneal disseminations were present. The tumor was histologically and immunohistochemically diagnosed to be a carcinoid tumor. The levels of serum serotonin and urinary 5-hydroxyindoleacetic acid (5-HIAA) were found to be significantly high. Imaging modalities and intraoperative findings showed no evidence of any tumors elsewhere. These findings led us to the diagnosis of a primary hepatic carcinoid tumor with carcinoid syndrome and carcinoid heart disease. The patient has been treated with ...
Goblet cell carcinoid tumor is a rare clinical entity which is usually diagnosed either as acute appendicitis or advanced cancer. Its main characteristic is that the histological findings are between those of adenocarcinoma and typical carcinoid tumor of the appendix. Goblet cell carcinoid tumors appear almost exclusively in the appendix, and prognosis depends mainly on the stage and the subtype of the histological classification. We report three cases of goblet cell carcinoid tumor in the appendix with different clinical presentation and evolution: a 60-year-old male admitted to the emergency room with acute abdominal pain, diagnosed with acute appendicitis and treated with laparoscopic appendectomy; a 65-year-old male undergoing right hemicolectomy to remove a cecal adenoma, with a goblet cell carcinoid tumor found incidentally in the surgical specimen; and a 77-year-old male with acute appendicitis. We discuss the main pathological and clinical findings, and propose a set of guidelines for clinical
Many risk factors may increase your chance of developing gastrointestinal carcinoid tumors. This guide will help you learn about possible causes of gastrointestinal carcinoid tumors.
Pulmonary carcinoids are rare neuroendocrine tumours of the lung. The molecular alterations underlying the pathogenesis of these tumours have not been systematically studied so far. Here we perform gene copy number analysis (n=54), genome/exome (n=44) and transcriptome (n=69) sequencing of pulmonary carcinoids and observe frequent mutations in chromatin-remodelling genes. Covalent histone modifiers and subunits of the SWI/SNF complex are mutated in 40 and 22.2% of the cases, respectively, with MEN1, PSIP1 and ARID1A being recurrently affected. In contrast to small-cell lung cancer and large-cell neuroendocrine lung tumours, TP53 and RB1 mutations are rare events, suggesting that pulmonary carcinoids are not early progenitor lesions of the highly aggressive lung neuroendocrine tumours but arise through independent cellular mechanisms. These data also suggest that inactivation of chromatin-remodelling genes is sufficient to drive transformation in pulmonary carcinoids.
Carcinoid tumors are rare. In early stage disease they may cause either no or few nonspecific symptoms. Therefore, patients with carcinoid tumors most often present late in the course of their illness when there is already progression to an incurable state as a result of metastatic disease. At present there are neither practical population screening tests nor effective therapies and hence the 5 year survival rate is low. Due to the rareness of sporadic carcinoid tumors, large scale genetic analysis and development of sensitive and specific diagnostic tests have not been successful. While kindreds with familial carcinoid tumors that are not ascribable to known genetic syndromes are exceedingly rare, they provide a unique opportunity to facilitate the identification of the responsible gene mutation. In addition, the mutated gene in the rare familial form may also underlie the origin of the more common sporadic occurrence of carcinoid tumors. We propose to study families in which there are at least ...
Discussion Neuroendocrine tumours of the uterine cervix are a rare cancer of the female reproductive system, accounting for approximately 1% of all female cervical malignancies.1 2 In 1997, a consensus workshop suggested four types of neuroendocrine tumours of the uterine cervix: typical and atypical carcinoid tumours, small cell neuroendocrine carcinomas, and large cell carcinomas.1 Among all the categories, small cell neuroendocrine carcinomas are of the highest incidence. A PubMed search revealed that only 15 cases of atypical carcinoid tumours of the uterine cervix have been reported.3 4 Because of infrequency, the clinical and pathological features of atypical carcinoid tumours of the uterine cervix remain unknown.. Atypical carcinoids are characterised by great cytological atypia, which means abundant or scanty cytoplasm and visible nucleoli with granular chromatin. Tumour cells lined up in insular, trabecular, columnar and nested organoid patterns; they are epithelioid in appearance, but ...
Carcinoid tumors represent an interesting family of tumors that are derived from neuroendocrine cells. With few exceptions, carcinoid tumors comprise a tiny fraction of tumors within any specific organ (11). These tumors were first described by Langhans (12) but were not described in detail until Lubarsch (13) described them in 1888. The name karzinoide was not used until 1907 by Oberndorfer (14), and was chosen to reflect his opinion that these were benign tumors. However, these tumors have a wide range of clinical presentations and diverse outcomes from benign to malignant. In the testis and in other organs, carcinoid tumors may behave aggressively and some investigators (15) have suggested that a designation of neuroendocrine carcinoma is more appropriate than carcinoid tumor; other investigators disagree with this approach (16).. The histogenesis of testicular carcinoid tumor has been a matter of debate (17). There is a strong rationale for the concept that testicular carcinoid tumor is ...

METHODS AND PROCEDURES From January 2001 to December 2010, total 299 patients with colorectal carcinoid tumors were treated at the National Cancer Center, South Korea. Among of them, we excluded patients who had metastatic disease(n=10), who underewent radical operation(n=33), who were diagnosed in other hospitals(n=83) and who had colon carcinoid tumors(n=3). Finally, 170 patients with 175 rectal carcinoid tumors, who treated with local excision including endoscopic resection and surgical resection were enrolled this study. A pathologically complete resection(P-CR) was defined as an en bloc resection with tumor-free lateral and deep margin. Local treatment methods were classified to conventional polypectomy including strip biopsy, snare polypectomy and hot biopsy, advanced endoscopic techniques including endoscopic mucosal resection with cap(EMR-C) and endoscopic submucosal dissection(ESD) and surgical local excision including transanal excision(TAE) and transanal endoscopic microsurgery(TEM). ...
Immunohistochemical studies showed that the tumor cells were reactive for chromogranin (Fig. 2b), TTF1, cytokeratin (CK)7, synaptophysin, neuron-specific enolase, focally positive for CD56 (Fig. 2c) and negative for S100 protein and CK20 (Fig. 2d).. Based on the patients history and scalp biopsy, a final diagnosis of skin metastasis of pulmonary atypical carcinoid tumor was made.. Cutaneous metastases (CM) occur in 0.7-9% of all patients with internal malignancies and metastatic tumor from carcinoid tumors represent an even smaller subset. Although visceral metastases of carcinoid tumors are common, CM are rare, and most CM are of bronchial origin.[1-3]. Cutaneous metastases tend to occur on the upper extremities, but can be found anywhere in the skin. CM are often painful and the pain is secondary to perineural invasion or to the release of vasoactive substances and peptide hormones, such as kallikrein and serotonin by carcinoid cells.[1-3] In our patient, we have assumed that the pain was ...
Primary neuroendocrine neoplasms of the lung represent a clinical spectrum of tumors ranging from the relatively benign and slow-growing typical carcinoid to the highly aggressive small-cell lung carcinoma. The rarity of carcinoids has made the role of radiation therapy in their management controversial. This review considers the results of published studies to generate treatment recommendations and identify areas for future research. Surgery remains the standard of care for medically operable disease. Histology plays the most important role in determining the role of adjuvant radiation. Resected typical carcinoids likely do not require adjuvant therapy irrespective of nodal status. Resected atypical carcinoids and large-cell neuroendocrine carcinomas have a significant risk of local failure, for which adjuvant radiation likely improves local control. Definitive radiation is warranted in unresectable disease. Palliative radiation for symptomatic lesions has demonstrated efficacy for all histologies.
What are Carcinoid Tumors?. The neuroendocrine system is made up of cells that connect the nervous system and the endocrine system. Neuroendocrine cells release hormones (sometimes called peptides) into the circulatory system in response to a stimulus received from the nervous system. These specialized cells are scattered throughout the organs in the body and are the cells that give rise to neuroendocrine tumors.. Neuroendocrine tumors (NETs) include both carcinoid tumors and pancreatic endocrine tumors (PETs). Carcinoid tumors represent the largest number of neuroendocrine tumors and pose a significant challenge to the clinician because they produce a unique clinical syndrome. Consequently, their diagnosis is difficult and often delayed. The clinician requires a high index of suspicion and confirmation with biochemical tests in order to establish their diagnosis. Because the majority of neuroendocrine tumors of the pancreas and carcinoid tumors that involve the wall of the gut have similar ...
Gastrointestinal carcinoid, also called carcinoid tumor, is the most common primary tumor of the small bowel and appendix. Gastrointestinal carcinoid accounts for more than 95% of all carcinoids.
Bronchial carcinoid tumors are very rare pulmonary neoplasms. They usually present with pulmonary symptoms or paraneoplastic syndromes. Typical (well-differentiated) tumors are usually indolent with survival exceeding 90% after resection. Atypical carcinoids have a worse prognosis. They are much more likely to recur locally or to have distant metastases. This case report describes a patient who presented with abdominal pain and hepatic lesions who was subsequently diagnosed to have bronchial carcinoid.
Carcinoid tumors are characteristically low grade malignant neoplasms with neuroendocrine differentiation that arise in various body sites, most commonly the lung and gastrointestinal tract, but less frequently the kidneys, breasts, ovaries, testes, prostate and other locations. We report a case of a carcinoid of renal origin with synchronous single liver metastases on radiological studies. A 45 year-old patient who presented with abdominal pain was found on CT scan to have lesions in the right ovary, right kidney, and left hepatic lobe. CA-125, CEA, and CA 19-9 were within normal limits, as were preoperative liver function tests and renal function. Biopsy of the liver mass demonstrated metastatic neuroendocrine tumor. At laparotomy, the patient underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy, radical right nephrectomy with lymphadenectomy, and left hepatectomy. Pathology evaluation reported a right ovarian borderline serous tumor, well-differentiated neuroendocrine carcinoma
The National Comprehensive Cancer Network (NCCN) recommends that tumor differentiation, mitotic rate, and Ki-67 rate be included in the pathology report and that the specific classification and grading scheme be noted to avoid confusion. Clinicians are advised to view histologic grade as a general guide and use clinical judgment to make treatment decisions, particularly in cases of discordance between differentiation and Ki-67 proliferation results. ...
The worldwide incidence of pulmonary carcinoids is increasing, but little is known about their molecular characteristics. Through machine learning and multi-omics factor analysis, we compare and contrast the genomic profiles of 116 pulmonary carcinoids (including 35 atypical), 75 large-cell neuroendocrine carcinomas (LCNEC), and 66 small-cell lung cancers. Here we report that the integrative analyses on 257 lung neuroendocrine neoplasms stratify atypical carcinoids into two prognostic groups with a 10-year overall survival of 88% and 27%, respectively. We identify therapeutically relevant molecular groups of pulmonary carcinoids, suggesting DLL3 and the immune system as candidate therapeutic targets; we confirm the value of OTP expression levels for the prognosis and diagnosis of these diseases, and we unveil the group of supra-carcinoids. This group comprises samples with carcinoid-like morphology yet the molecular and clinical features of the deadly LCNEC, further supporting the previously ...
Though carcinoids are slow growing tumors, which can be treated by surgery, the survival in metastatic carcinoids is very low because the treatment strategies for other cancers are not effective for dealing with advanced stage carcinoids [36]. Therefore, the investigations concerning the discovery of new strategies for treating pulmonary carcinoids need to be focused on therapies that can inhibit the growth and invasiveness of advanced stage disease. Carcinoid tumors are proving moderately responsive to newer therapies targeting tumor vasculature and survival pathways [1, 2]. The mammalian target of rapamycin (mTOR) inhibitor, everolimus, has shown promising initial results alone or combined with other agents [37-39]. Bronchial AC, which is characterized by high mTOR expression, has been reported to be responders to mTOR inhibition, indicating that therapies targeting the critical survival pathways are potential candidates to treat bronchial carcinoids [40]. The evidence seems to indicate that ...
The carcinoids are a neuroendocrine group of tumors, arising from Kulchitsky cells. They can arise from along the gastrointestinal tract or the bronchial mucosa. The tumor can Release serotonin may produce carcinoid syndrome (flushing, diarrhea, and wheezing). Carcinoid was defined in 1907 by Oberndorfer but is now more relevantly named as the neuroendocrine tumor [2]. The origin of neuroendocrine tumors of the mediastinum is either from thymus or from the ectopic neuroectodermal tissue. Rosai and Higa are credited with the first description of such tumors in the thymic region [5]. There is the marginal relevance of the precise distinction between thymic and mediastinal carcinoids [6]. However, few cases of posterior mediastinal carcinoid tumor reported so far have been attributed to ectopic thymic tissue [7]. Clinically, patients may be asymptomatic or may present with symptoms of compression of the mediastinal structures [7]. As but our patient present with dry a cough and dyspnea since six ...

Gastrointestinal tract carcinoid tumors have a nonspecific clinical presentation, except in the case of the carcinoid syndrome. Surgical resection is the treatment of choice for improving survival. Surgically treated patients with carcinoid tumor have an overall favorable 83% 5-year survival rate.
RADIOLOGY: LUNG: Case# 14: BRONCHIAL CARCINOID. 17-year-old female with asthma who presented with opacified left hemithorax on chest x-ray. Bronchoscopy, with rigid bronchoscope, showed left main stem bronchial occlusion. There is complete atelectasis of the left lung. This is an obstructive type atelectasis with bronchially dilated fluid-filled bronchograms seen throughout the lungs. Fluid-filled bronchograms are seen to the level of the left main stem arising near the carina. A small to moderate size pleural effusion is seen surrounding the left lung. There has been shift of the mediastinum towards the left slightly. This is most evident on the lower mediastinum. There are no enlarged mediastinal lymph nodes identified. The right lung appears normal without any air space opacities or pleural abnormality. Bronchial carcinoid tumors are relatively rare, accounting for approximately 5% of primary lung tumors. They may range from low-grade malignant typical carcinoid, which has a 5-year survival rate

People and organisations will be out of date with modern Neuroendocrine Neoplasms nomenclature and some will still want to continue with their own nomenclature (….. and because of the confusion, some will fall into both categories not realising theyre out of date). Heres a classic example of the problem we face - the American Cancer Society(ACS) does not even list Neuroendocrine Tumor as a cancer type. Instead you can find Gastrointestinal Carcinoid Tumors and Lung Carcinoid Tumor. Youll find Pancreatic NETs inside Pancreatic Cancer. Americans should harangue the ACS to get this right. I could go on with many similar observations on seemingly respectable sites. I intentionally used a US example as this country appears to be way behind in the changes to NET nomenclature, pretty surprising as they tend to be at the forefront of many other aspects in the world of NETs.. Personally, I think the acceptance of a common worldwide nomenclature should come from the World Health Organisation ...

Argentaffin refers to cells which take up silver stain.[1] Enteroendocrine cells are sometimes also called argentaffins, because they take up this stain. An argentaffin cell is any enteroendocrine cell, a hormone-secreting cell present throughout the digestive tract. It is a property of melanin, and special stain can be applied to identify those granules. Fontana-Masson stain uses the fact that those cells can reduce the silver salts to metallic silver (brownish-black) color without the aid of reducing agent, which is the definition of Argentaffin cells. Argentaffin cell, one of the round or partly flattened cells occurring in the lining tissue of the digestive tract and containing granules thought to be of secretory function. These epithelial cells, though common throughout the digestive tract, are most concentrated in the small intestine and appendix. The cells located randomly within the mucous membrane lining of the intestine and in tubelike depressions in that lining known as the ...
The aim was to investigate HRQoL and psychosocial function among patients with carcinoid tumours, longitudinally and prospectively, and to compare HRQoL among patients with carcinoid tumours to that of the Swedish general population. The aim was also to investigate the prevalence of distress during the first year after diagnosis. At four assessments during the first year after diagnosis, HRQoL was measured by the EORTC QLQ-C30 3.0, anxiety and depression by the HADS, and prevalence, and worst aspects of distress by an interview guide. ANOVA was performed in order to study changes over time with regard to HRQoL, anxiety and depression. Comparisons regarding HRQoL between patients and the Swedish population were made by the use of one-sample t-tests and changes over time regarding the prevalence of distress was investigated by means of Cochrans Q. High levels of physical-, emotional-, cognitive-, and social function and somewhat lower levels of role function and global quality of life were reported at
Carcinoid tumors are rare, slow growing tumors that are formed by the endocrine cells in the mucosal lining of organs, such as the stomach and intestine. These tumors are small neuroendocrine tumors, typically of the gastrointestinal tract, that secrete serotonin, a naturally occurring neurochemical that is usually associated with sleep and memory functions.
Introduction: Gastric endocrine tumors (GET) are increasingly recognized due to expanding indications of upper gastrointestinal endoscopy. Often silent and benign, GET may also be aggressive when sporadic and may sometimes mimic the course of gastric adenocarcinoma. Current incidence of GETs is estimated at around 8% of digestive endocrine tumors. Yearly age-adjusted incidence is around 0.2 per population of 100,000. Gastric carcinoids (ECLomas) develop from gastric enterochromaffin-like cells (ECL cells) in response to chronically elevated gastrin. Type 1 tumors (ECLomas in the course of atrophic gastritis) may occur in conditions of achlorhydria secondary to auto-immune atrophic fundic gastritis. It occurs mostly in women and they are non-functioning tumors, typically found during upper GI endoscopy performed for dyspepsia. ECLomas present frequently as multiple polyps, usually , 1 cm in diameter in the gastric fundus. Type 1 tumors are almost exclusively benign lesions with little risk of ...

A carcinoid tumor that secretes serotonin or other chemicals into the bloodstream is the cause of carcinoid syndrome. The gastrointestinal tract, including the appendix, colon and rectum, small intestine, stomach, or in the lungs, are some of the places where carcinoid tumors occur most commonly. Carcinoid tumors may develop in the ovaries in some rare cases. The chemicals that cause carcinoid syndrome are secreted only by a small percent of carcinoid tumors, however, these tumors dont have to be advanced to cause carcinoid syndrome. Usually, before these chemicals have a chance to travel through the body and affect it causing symptoms, the liver degrades and neutralizes them in an effective way. But when an advanced tumor spreads (metastasizes) to the liver itself, the chemicals that are secreted by these metastases wont be degraded as efficiently before they reach the bloodstream. Instead of secreting chemicals directly into the liver where the chemicals are processed and eliminated, the ...
Carcinoid tumors are a type of neuroendocrine tumor that can occur in a number of locations. Carcinoid tumors arise from endocrine amine precursor uptake and decarboxylation (APUD) cells that can be found throughout the gastrointestinal tract as well as other organs (e.g. lung). In general, they are slow-growing tumors but are nevertheless capable of metastasizing.. ...

Carcinoid tumors are rare (2.5 to 5.0 cases per 100,000 of the population per year), slow-growing neuroendocrine malignancies with significant potential to produce hepatic metastases and release excessive amounts of vasoactive amines into the systemic circulation (1). As a consequence, up to 15% of patients may develop carcinoid syndrome, with cutaneous flushing, gastrointestinal hypermotility, and cardiac involvement. Cardiac manifestations, also known as carcinoid heart disease (CaHD), are caused by endocardial deposition of pearly fibrotic plaques (notable for absence of elastic fibers) that generally extend to the right-sided valves, leading to multiple patterns of severe valve dysfunction. Plaque formation causes annular constriction, leaflet thickening, and fusion of the subvalvular apparatus. Marked degeneration of the leaflet architecture leads to severe retraction and noncoaptation of the valve, which remains fixed in a semiopen position (2). In this setting, valve replacement is the ...

Neuroendocrine tumors arise from the diffuse neuroendocrine system and secrete several peptides and bioactive amines (serotonin, histamine, dopamine, norepinephrine, corticotropin, calcitonin, bradykinin, kalikrein, gastrin, cholecystokinin, prostaglandins). The most common occurrence site of neuroendocrine tumors is the ileum. The symptoms of small bowel carcinoids are represented by intermittent intestinal obstruction and carcinoid syndrome. Presence of the carcinoid syndrome usually indicates hepatic or retroperitoneal metastases. The typical carcinoid syndrome is characterized by flushing, diarrhea, nonspecific abdominal pain and bronchospasm. The diagnosis of small bowel tumors is often difficult due to their rarity and the nonspecific and variable nature of the presenting signs and symptoms. The most useful initial diagnostic test for the carcinoid syndrome is to measure 24-hour urinary excretion of 5-hydroxyindolacetic acid (5 HIAA), which is the end product of serotonin metabolism. ...
4F2hc (CD98) has been associated with tumor growth, and is highly expressed in various tumors. The aim of this study was to evaluate the clinicopathological significance of 4F2hc expression in pulmonary neuroendocrine (NE) tumors. Surgically-resected patient tumors including 16 large cell neuroendocrine carcinoma (LCNEC), 12 small cell lung cancer (SCLC), 1 atypical carcinoid (AC) and 5 typical carcinoid (TC) samples were included in this study.

Mutations of the MEN1 gene located on chromosome 11q13 are associated with the development of a variety of endocrine neoplasms, including parathyroid hyperplasia and adenomas, pituitary adenomas, and pancreatic islet cell tumors. Tumor development is associated with deletion or mutation of the remaining MEN1 allele (1, 2). MEN1 mutations have also been reported in a variety of sporadic endocrine tumors including those commonly seen in multiple endocrine neoplasia syndrome type 1 (MEN1) as well as gastric and pulmonary carcinoid tumors (3). Men1 knockout mice have provided many insights into the role of menin in endocrine homeostasis and tumor suppression (4-7). Although Men1 knockout mice are embryonic lethal, heterozygous mice develop a variety of endocrine tumors similar to those in MEN1 patients. In this model, tumors arising from pancreatic islet cells have been most intensively studied. Heterozygous Men1 knockout mice develop progressive islet cell hyperplasia associated with loss of the ...

I have a patient who comes in with vague respiratory and gi symptoms. They did a chest xray and found a lung mass. They are now working him up for a probable lung ca, with mets to various places. In the old coding I would use ca-nyd. I actually use the ca nyd subcode a lot. Ive talked to you about this before, because there is no ca nyd in icd10. You told me that you either have cancer or you dont. For this particular patient I really wouldnt have anything else I could code in icd10 for him. His symptoms are extremely vague. I dont really like coding just symptoms, if there isnt a proper admit diagnosis that fits better anyway. I found a neoplasm of uncertain behavior (i.e. uncertain if benign or malignant), nos, but I dont really like that one. It doesnt really fit. Is it possible to get something like admit for workup of malignancy, or something along those lines? (Debbie, 12:40, 2018 October 4 (CDT)) How should this be coded?

Eric Nakakura, M.D., Ph.D., a UCSF gastrointestinal cancer surgeon and Emily Bergsland, M.D.. a UCSF gastrointestinal oncologist, recently discussed the treatment of carcinoid syndrome on Healthy Body, Healthy Mind, a series hosted by Information Television Network (ITV), a PBS content affiliate. Dr. Nakakura is an Associate Professor in the UCSF Department of Surgery and Dr. Bergsland a Professor in the UCSF Department of Medicine.. The ITV episode, which portrays the struggles of Ray Martz with carcinoid syndrome, recounts the situation he initially faced - that his condition was inoperable, that he would be on a liquid diet indefinitely, and that nothing further could be done. Unwilling to accept that outcome, Mr. Martz sought treatment at UCSF Medical Center in the the GI Oncology Program, a multidisciplinary team of specialists with extensive experience in diagnosing and treating carcinoid syndrome.. Carcinoid syndrome occurs when a carcinoid tumor, a rare cancerous tumor, secretes an ...
Answer: Metastatic well-differentiated neuroendocrine neoplasm (carcinoid tumor). Histology: The tumor has a papillary architecture where the tumor cells are arranged surrounding dilated thin walled blood vessels.The nuclei are oval to round with little pleomorphism and have finely dispersed chromatin.Mitoses are not readily identified.. Discussion: The tumor cells are positive for cytokeratin (AE1/AE3 - image 6),chromogranin,synaptophysin and are negative for CK7,CK20,CK17,Heppar-1 and TTF-1.This staining pattern supports the diagnosis of metastatic well differentiated neuroendocrine neoplasm (carcinoid tumor).In order to determine possible origin and biologic behavior immunostains were performed for CDX-2 (gastrointestinal origin),PAX-8(pancreatic origin) and Ki67.The tumor cells are negative for PAX8(image 7)and positive for CDX-2(image 8).This staining pattern favors a gastrointestinal origin. The Ki67 proliferation index is ,2%(image 9)consistent with a low grade neuroendocrine neoplasm. ...

This study reports a positive association between saturated fat intake and carcinoid tumors of the small intestine. Small intestinal cancer arises from various cell types; ∼35% tend to be carcinoids, 30% to 40% adenocarcinomas, 15% to 20% lymphomas, and 10% to 15% sarcomas ( 15). In agreement with previous findings from case-control studies ( 16), the cases in this prospective study were mainly adenocarcinomas of the duodenum and jejunum and carcinoids of the ileum. Previous studies have suggested that risk factors for this malignancy may differ according to histologic subtype ( 14), yet no previous dietary study has had the power to investigate risks within the subtype of incident carcinoid tumors.. The association between meat intake and cancer has been investigated for various anatomic sites, with the majority of studies focusing on subsites within the gastrointestinal tract. The evidence supporting red meat and processed meat as risk factors for colorectal cancer is increasingly consistent ...

A 54-year-old man who had an appearance strongly suggestive of Cushings syndrome, collapsed after the removal of a carcinoid tumour of the thymus. The clinical suspicion of acute adrenal insufficiency was supported by invasive haemodynamic data and the diagnosis was subsequently confirmed biochemically. These post-operative events were subsequently ignored and a further crisis was probably prevented by tumour recurrence (and hence resumption of adrenocorticotropic hormone (ACTH) production). The ectopic production of ACTH from a carcinoid tumour of the thymus is recognised but a report of acute adrenal insufficiency from its removal is probably unique.. ...

5-HIAA (5-Hydroxyindoleacetic acid) is the major urinary metabolite of serotonin, an ubiquitous bioactive amine. Serotonin, and consequently 5-HIAA, are produced in excess by most carcinoid tumors, especially those producing the carcinoid syndrome. Quantification of urinary 5-HIAA is therefore intended to test for carcinoid ...
Donna Angelo knew something was wrong inside her body. She could feel it. Despite dismissals by doctors saying it was nothing and one misdiagnosis after another, she knew no one had discovered the truth. Something was terribly wrong inside her body and it was something out of the ordinary. Today, Angelo knows the truth. She had one of the rarest forms of cancer - malignant neuroendocrine tumors, which account for less than 1 percent of all malignant disorders in the United States. Most physicians are not even familiar with the disease. Angelo said she is sharing her story because the nightmare of knowing something is wrong, but not knowing what it is, can be a harrowing ordeal. It can also happen to anyone unless the public and physicians raise their awareness about this rare cancer. Angelo and her husband, Bobby, were a Rhode Island couple who moved to Florida where she worked as a marketing rep for a pharmaceutical company until Feb. 2011. I had always had digestive issues, she confessed. ...

Im not happy with this product at all becuase I dont think that its safe. Theres too many people online screaming about how great 5-htp is but please read this article and try to see things from another angle. I sujest everyone including myself to do a research before taking anything inside the body. It has been shown that excessive 5-HTP can cause heart valve damage much in the same scenario as the naturally occurring carcinoid syndrome. Carcinoid syndrome is a disorder that develops when a tumor releases 5-HTP. The tumor is usually located in the last section of the small intestine but may also be located in the rectum, appendix, lungs or pancreas. Quote: In a 2005 issue of Circulation, Bjorn Gustafsson, M.D., and coauthors reported on research designed to determine if rats given 5-HTP would develop changes like those seen in carcinoid syndrome. Ten rats that received injections of serotonin once a day for three months developed a deficiency of platelets, as well as diarrhea and ...

Most people who have an uncomplicated skin abscess should not use antibiotics.[4] Antibiotics in addition to standard incision and drainage is recommended in persons with severe abscesses, many sites of infection, rapid disease progression, the presence of cellulitis, symptoms indicating bacterial illness throughout the body, or a health condition causing immunosuppression.[1] People who are very young or very old may also need antibiotics.[1] If the abscess does not heal only with incision and drainage, or if the abscess is in a place that is difficult to drain such as the face, hands, or genitals, then antibiotics may be indicated.[1] In those cases of abscess which do require antibiotic treatment, Staphylococcus aureus bacteria is a common cause and an anti-staphylococcus antibiotic such as flucloxacillin or dicloxacillin is used. The Infectious Diseases Society of America advises that the draining of an abscess is not enough to address community-acquired methicillin-resistant Staphylococcus ...

... (MC), sometimes called water warts, is a viral infection of the skin that results in small, raised, pink lesions with a dimple in the center.[1] They may occasionally be itchy or sore.[1] They may occur singularly or in groups.[1] Any area of the skin may be affected, with abdomen, legs, arms, neck, genital area, and face being most common.[1] Onset of the lesions is around 7 weeks after infection.[3] It usually goes away within a year without scarring.[1] MC is caused by a poxvirus called the molluscum contagiosum virus (MCV).[1] The virus is spread either by direct contact including sexual activity or via contaminated objects such as towels.[4] The condition can also be spread to other areas of the body by the person themselves.[4] Risk factors include a weak immune system, atopic dermatitis, and crowded living conditions.[2] Following one infection, it is possible to get reinfected.[9] Diagnosis is typically based on the appearance.[3] Prevention includes hand washing ...

In terms of pathology, the first signs of the condition may be observed within the dermis. The changes that may take place at this level may include edema, vascular dilatation, and cellular infiltration. It is common for lymphocytes and eosinophils to be seen. The bullae found in the skin affected by dermatitis herpetiformis are subepidermal and have rounded lateral borders. When looked at under the microscope, the skin affected by dermatitis herpetiformis presents a collection of neutrophils. They have an increased prevalence in the areas where the dermis is closest to the epidermis. Direct IMF studies of uninvolved skin show IgA in the dermal papillae and patchy granular IgA along the basement membrane. The jejunal mucosa may show partial villous atrophy, but the changes tend to be milder than in coeliac disease.[18] Immunological studies revealed findings that are similar to those of coeliac disease in terms of autoantigens.
