Alterations of Rb pathway (Rb-p16INK4-cyclin D1) in preinvasive bronchial lesions. (1/530)

Lung cancer results from a stepwise accumulation of genetic and molecular abnormalities with unknown temporal relationships to precursor bronchial lesions. In a search for biomarkers of malignant progression, we analyzed the expression of the tumor suppressor gene Rb and of the proteins regulating its phosphorylation and function in G1 arrest, p16INK4A and cyclin D1, in preinvasive bronchial lesions accompanying cancer in 75 patients, in comparison with similar lesions in 22 patients with no cancer history. Rb was constantly expressed in preinvasive lesions, including carcinoma in situ (CIS). In contrast, p16 expression was lost in moderate dysplasia (12%) and in CIS (30%) in patients with lung cancer. p16 loss occurred exclusively in patients who displayed loss of p16 expression in their related invasive carcinoma. Loss of p16 expression was not seen in nine patients with dysplasia but no cancer progression. Cyclin D1 overexpression was seen in hyperplasia and metaplasia (6%), mild dysplasia (17%), moderate dysplasia (46%), and CIS (38%) in patients with cancer but was lost in 5% of the patients during the process of invasion; it was also observed in patients with no cancer progression (14%). Our results indicate that Rb protein function can be invalidated before invasion through alteration of the Rb phosphorylation pathway, by p16 inhibition, and/or by cyclin D1 overexpression and suggest a role for p16 and cyclin D1 deregulation in progression of preinvasive bronchial lesions to invasive carcinoma.  (+info)

Differential responses of normal, premalignant, and malignant human bronchial epithelial cells to receptor-selective retinoids. (2/530)

Using an in vitro lung carcinogenesis model consisting of normal, premalignant, and malignant human bronchial epithelial (HBE) cells, we analyzed the growth inhibitory effects of 26 novel synthetic retinoic acid receptor (RAR)- and retinoid X receptor (RXR)-selective retinoids. RAR-selective retinoids such as CD271, CD437, CD2325, and SR11364 showed potent activity in inhibiting the growth of either normal or premalignant and malignant HBE cells (IC50s mostly <1 microM) and were much more potent than RXR-selective retinoids. Nonetheless, the combination of RAR- and RXR-selective retinoids exhibited additive effects in HBE cells. As the HBE cells became progressively more malignant, they exhibited decreased or lost sensitivity to many retinoids. The activity of the RAR-selective retinoids, with the exception of the most potent retinoid, CD437, could be suppressed by an RAR panantagonist. These results suggest that: (a) RAR/RXR heterodimers play an important role in mediating the growth inhibitory effects of most retinoids in HBE cells; (b) CD437 may act through an RAR-independent pathway; (c) some of the RAR-selective retinoids may have the potential to be used in the clinic as chemopreventive and chemotherapeutic agents for lung cancer; and (d) early stages of lung carcinogenesis may be responsive targets for chemoprevention by retinoids, as opposed to later stages.  (+info)

Cyclin D1 proteolysis: a retinoid chemoprevention signal in normal, immortalized, and transformed human bronchial epithelial cells. (3/530)

BACKGROUND: Retinoids (derivatives of vitamin A) are reported to reduce the occurrence of some second primary cancers, including aerodigestive tract tumors. In contrast, beta-carotene does not reduce the occurrence of primary aerodigestive tract cancers. Mechanisms explaining these effective retinoid and ineffective carotenoid chemoprevention results are poorly defined. Recently, the all-trans-retinoic acid (RA)-induced proteolysis of cyclin D1 that leads to the arrest of cells in G1 phase of the cell cycle was described in human bronchial epithelial cells and is a promising candidate for such a mechanism. In this study, we have investigated this proteolysis as a common signal used by carotenoids or receptor-selective and receptor-nonselective retinoids. METHODS: We treated cultured normal human bronchial epithelial cells, immortalized human bronchial epithelial cells (BEAS-2B), and transformed human bronchial epithelial cells (BEAS-2BNNK) with receptor-selective or receptor-nonselective retinoids or with carotenoids and studied the effects on cell proliferation by means of tritiated thymidine incorporation and on cyclin D1 expression by means of immunoblot analysis. We also examined whether calpain inhibitor I, an inhibitor of the 26S proteasome degradation pathway, affected the decline (i.e., proteolysis) of cyclin D1. RESULTS: Receptor-nonselective retinoids were superior to the carotenoids studied in mediating the decline in cyclin D1 expression and in suppressing the growth of bronchial epithelial cells. Retinoids that activated retinoic acid receptor beta or retinoid X receptor pathways preferentially led to a decrease in the amount of cyclin D1 protein and a corresponding decline in growth. The retinoid-mediated degradation of cyclin D1 was blocked by cotreatment with calpain inhibitor I. CONCLUSIONS: Retinoid-dependent cyclin D1 proteolysis is a common chemoprevention signal in normal and neoplastic human bronchial epithelial cells. In contrast, carotenoids did not affect cyclin D1 expression. Thus, the degradation of cyclin D1 is a candidate intermediate marker for effective retinoid-mediated cancer chemoprevention in the aerodigestive tract.  (+info)

Survey of outpatient sputum cytology: influence of written instructions on sample quality and who benefits from investigation. (4/530)

OBJECTIVES: To evaluated quality of outpatient sputum cytology and whether written instructions to patients improve sample quality and to identify variables that predict satisfactory samples. DESIGN: Prospective randomised study. SETTING: Outpatient department of a district general hospital. PATIENTS: 224 patients recruited over 18 months whenever their clinicians requested sputum cytology, randomized to receive oral or oral and written advice. INTERVENTIONS: Oral advice from nurse on producing a sputum sample (114 patients); oral advice plus written instructions (110). MAIN MEASURES: Percentages of satisfactory sputum samples and of patients who produced more than one satisfactory sample; clinical or radiological features identified from subsequent review of patients' notes and radiographs associated with satisfactory samples; final diagnosis of bronchial cancer. RESULTS: 588 sputum samples were requested and 477 received. Patients in the group receiving additional written instructions produced 75(34%) satisfactory samples and 43(39%) of them one or more sets of satisfactory samples. Corresponding figures for the group receiving only oral advice (80(31%) and 46(40%) respectively)were not significantly different. Logistic regression showed that radiological evidence of collapse or consolidation (p<0.01) and hilar mass (p<0.05) were significant predictors of the production of satisfactory samples. Sputum cytology confirmed the diagnosis in only 9(17%) patients with bronchial carcinoma. CONCLUSIONS: The quality of outpatients' sputum samples was poor and was not improved by written instructions. Sputum cytology should be limited to patients with probable bronchial cancer unsuitable for surgery. IMPLICATIONS: Collection of samples and requests for sputum cytology should be reviewed in other hospitals.  (+info)

Sex-related differences in bronchial epithelial changes associated with tobacco smoking. (5/530)

BACKGROUND: Lung cancer is the most common cause of cancer death in North American women. Because smoking-related changes in the bronchial epithelium and in lung function have not been studied in detail in women, we used fluorescence bronchoscopy-directed biopsy to determine the prevalence of high-grade preinvasive lesions in former and current smokers of both sexes. METHODS: Spirometry, white-light bronchoscopy, and fluorescence bronchoscopy were performed in 189 women and 212 men older than 40 years of age who had smoked 20 pack-years or more (pack-years = number of packs of cigarettes smoked per day x number of years of smoking). RESULTS: Carcinoma in situ was found in 1.8% of the subjects, severe dysplasia was found in 6.5%, and moderate dysplasia was found in 14% (all preinvasive lesions). Compared with men, women had a lower prevalence of high-grade preinvasive lesions in the observed airways (14% versus 31%; odds ratio = 0.18; 95% confidence interval = 0.04-0.88), and women with preinvasive lesions had fewer such lesions (two-sided P = .048). The prevalence of preinvasive lesions did not change substantially for more than 10 years after cessation of smoking. Lung function was associated with the prevalence of preinvasive lesions, but the association was weaker in women than in men. If the presence of airflow obstruction was defined by an FEV1/FVC (forced expiratory volume in 1 second/forced vital capacity) value of 70% or less, only 56% of the men and 44% of the women with preinvasive lesions had abnormal lung function. CONCLUSION: In developing strategies for chemoprevention or early detection of lung cancer in high-risk populations, it is important to consider the effect of sex and arbitrarily chosen lung function values on the prevalence of preinvasive airway lesions.  (+info)

Malignant tumors of the liver and lungs in an area with a PVC industry. (6/530)

The incidence of malignant tumors of the lung and bronchus and of cytologically confirmed primary malignant tumor of the liver was analyzed for a 4-yr period in a city with several factories, including a PVC industry. Prior to the study two cases of angio-sarcoma of the liver were diagnosed in workers employed in PVC production. The total incidence of analyzed tumors was only slightly higher than predicted. The tumors of the liver recorded did not show any dependence on place of work or residence. During the period of observation, malignant tumors of the bronchus (lung) were not recorded in the PVC industry. Their rate in the area in which the PVC industry is situated was approximately the same as that for the entire city area. The study does not indicate that the occurrence of malignant tumors other than angiosarcoma is associated with exposure to vinyl chloride.  (+info)

Overexpression of cyclins D1 and E is frequent in bronchial preneoplasia and precedes squamous cell carcinoma development. (7/530)

Increased protein expression of the G1 cyclins D1 and E is reported in invasive non-small cell lung carcinoma. However, during transformation of the bronchial epithelium, overexpression of these species occurs, and their relationship to aberrant expression of p53 and retinoblastoma (Rb) has not been described previously. To determine the expression of these cell cycle regulators during the development of invasive squamous cell carcinoma (SCC) of the lung, the immunohistochemical expression patterns in normal bronchial epithelium (n = 36), squamous metaplasia (SM; n = 28), and epithelial atypia (n = 34) were compared with that in low-grade dysplasia (LGD; n = 17), high-grade bronchial dysplasia (HGD; n = 30), and SCC (n = 36). Monoclonal anti-p53 Pab1801, polyclonal anti-cyclin D1 DCS6, monoclonal anti-cyclin E HE12, and monoclonal anti-Rb OP-66 antibodies were used. Cyclin D1 was not expressed in normal bronchial epithelium but was detected in 7% of SMs, 15% of atypias; 18% of LGDs, 47% of HGDs, and 42% of SCCs. Cyclin E was not detected in normal epithelium (n = 24), SM (n = 16), or LGD (n = 12), but it was found in 9% of atypias (2 of 22), 33% of HGDs (7 of 21), and 54% of SCCs (13 of 24). p53 was not expressed in normal epithelium, SM, and LGD, but it was overexpressed in 6% of atypias, 53% of HGDs, and 61% of SCCs. Abnormal Rb expression was found only in 2 of 36 cases of SCC. A total of 91% of HGDs and 92% of SCCs exhibited overexpression of at least one of the p53, cyclin D1, or cyclin E species. However, no link was observed between overexpression of p53 and the overexpressed G1 cyclins in preneoplastic lesions. Overexpression of cyclin D1, cyclin E, and p53 occurs frequently and independently in pulmonary SCC and is detected in lesions before the development of invasive carcinoma. In contrast, altered Rb expression is a late and infrequent event in squamous cell carcinogenesis.  (+info)

Bronchial capillary hemangioma in adults. (8/530)

Two cases with capillary hemangioma of the trachea and the left upper lobe bronchus are presented. The adult patients were referred to the hospital because of hemoptysis and cough. The chest radiographs were normal in both cases. The bronchoscopic examination revealed circumscribed lesions with a capillarized surface protruding into the lumen of the trachea and the left upper lobe bronchus, respectively. The lesions were excised in toto with flexible bronchoscopic forceps. The specimens contained typical capillary hemangiomas without any signs of malignancy. Capillary hemangioma in the bronchial tree is an extremely rare benign lesion in adults. Nevertheless, it should be considered as a possible cause of hemoptysis and cough.  (+info)

Endobronchial tumors cannot be visualized on standard two-view chest radiographs. The tumor is often associated with other phenomena, such as postobstructive pneumonia, atelectasis, and adenopathy. Chest CT scans may demonstrate a mass or adenopathy. In the present case, no mediastinal or hilar adenopathies were noted.6,7 Although there is a better chance of visualizing an endobronchial tumor by means of a CT scan than by means of a standard radiograph, endobronchial tumors can remain elusive on CT scans.1,7 Three-dimensional computer reconstruction (eg, virtual bronchoscopy) may be helpful in visualizing elusive tumors before invasive imaging becomes necessary. Virtual bronchoscopy uses CT images and various computer graphic systems to create a computerized graphic image of the endobronchial tree.8,9 The role of virtual bronchoscopy has yet to be fully defined with data to support its use in diagnosing endobronchial lesions.8,9 The preferable method for diagnosing an endobronchial tumor is ...

We have previously demonstrated that vascular count significantly increases in the preneoplastic lesions of the bronchial tree, starting from very low levels in the normal epithelium to a significantly higher number of microvessels in moderate dysplastic lesions and in situ carcinomas. Vascular endothelial growth factor (VEGF) protein expression has shown to be strictly associated with neovascularization both in human cancer and in various type of preinvasive lesions. A number of studies have demonstrated that mutant p53 is involved in the regulation of angiogenesis, and immunohistochemical detection of the p53 protein is associated with p53 gene mutations. In this study we looked for possible correlation between p53 protein detection, VEGF expression and vascular count in a series of preneoplastic and neoplastic lesions of the bronchial tree in order to investigate the angiogenic pattern and its genetic control in the early steps of bronchial cancer development. Twenty-four retrospective ...
CSÁNKY Eszter. [Despite decades of smoking cessation programs, and lung cancer screening programs, mortality due to bronchial cancer leads the mortality statistics among cancer deaths worldwide. Platinum-based chemotherapy has not fundamentally altered the effectiveness of treating non-small cell lung cancer (NSCLC). One of the newest approaches to the use of immunotherapeutic treatments in recent years is the so-called. use of immune checkpoint blocking agents. PD-1 and PD-L1 blockers of this type have been subjected to a large number of clinical trials in lung cancer and were reported by the tumor III.b / IV. stage.

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.
Results. The m/f rate was 0.6, the average age 42.5 years and the smokers percentage 42.8. The patients were symptomatic in 88.6% of cases. The carcinoid was located in the right lung in 17 patients (48.5%) and central in 29 patients (82.8%). Surgical treatment included pneumonectomy (6), lobectomy (17), bilobectomy (3), sleeve lobectomy (2), sleeve bilobectomy (1), sleeve resection of main bronchus (1), bronchotomy and tumorectomy (3) and wedge parenchymal resection (2). Thirty patients (85.7%) presented a typical carcinoid and five (14.3%) atypical carcinoid. Peribron-chial and/or hilar lymphonodal metastases were present at surgery in 2 cases (5.7%), both centrally located and atypical. The typical carcinoids showed a real 5 years survival rate of 95.8% (with only one death, not related to the neoplasm), while that of the atypical carcinoids was 80% (one patient died of multiple metastases ...

Hamartomas are benign tumor-like malformations which was originally described by Albrecht.1 Hamartomas of the lung can be pulmonary or endobronchially. A 37-year-old female was admitted to our hospital with a 3-month history of progressive dyspnea. She had a 20 pack-year smoking history. Physical examination revealed decreased respiratory sounds in the left lung field. The chest X-ray showed atelectasis of the left lower lobe (Fig. 1a). Computed tomography revealed a 2cm×3cm×1.5cm homogeneous mass, obstructing the left lower bronchus. Rigid bronchocopy was done for diagnosis and treatment to maintain airway safety. A vegetating, pedunculated lesion covered with a normal bronchial epithelium was observed obstructing the entrance of the left main bronchus (Fig. 1c). Distal bronchus was observed to be patent. The tumor was extracted with the snare prob and cryotherapy was applied to the base of the tumor (Fig. 1d). Postoperatively, the dyspnea subsided and the atelectasis in the left lower lobe ...
Here, we report the successful treatment of a 40-year-old man with mucoepidermoid carcinoma that originated in the proximal end of the left main bronchus close to the carina. He underwent wide and deep airway wedge resection, including the distal trachea and part of the carina via left postero-lateral thoracotomy. He has demonstrated neither anatomic complications nor disease recurrence 2 years after the operation.
Etiology of bronchial obstruction: a) spasm; b) mucous odema; c) hypersecretion; d) scar narrowing: e) endobronchial tumor; f) external pressuring of bronchus. Surgical procedure is typically useful for COPD in chosen cases. A bullectomy is the surgical elimination of a bulla, a large air-stuffed space that can squash the encircling, more normal lung. Lung volume reduction surgery is similar; parts of the lung which might be significantly broken by emphysema are eliminated permitting the remaining, relatively good lung to increase and work better. Lung transplantation is sometimes carried out for extreme COPD, significantly in youthful people..

Introduction: Bronchial carcinoids (BC) are rare neuroendocrine tumors. Surgery is not feasible for infiltrating and metastatic disease. Medical therapy is often tried but is represented by chemotherapy and radiation, while somatostatin analogues are employed for symptomatic control. It is necessary to identify new molecules capable of providing medical treatment in cases for which surgical removal is not feasible. EGF, TGFα are growth factors which were demonstrated to be important in neuroendocrine tumors. EGF and TGFα bind to the EGF receptor and lead to the transcription of genes that regulate cell proliferation ...

Excluding those cases that merits surgical treatment, endoscopic mechanical debulking in conjunction with other techniques actually are the preferred method of treatment as it results in complete resection and preserve lung parenchyma.1 These tumors are poorly vascularized and patients rarely present with hemoptysis, and if that is the case, it has been mainly attributed to post obstructive pneumonia or bronchiectasis rather than the tumor itself.2 With all of this in mind, we recently decided to resect a previously histologically confirmed endobronchial pedunculated lipoma which obstructs the intermediary bronchus (Fig. 1A) from a 69-year old never smoker man who has a history of recurrent right lower pneumonia and with the aid of a cold snare device (Fig. 1B) intended for percutaneous endoscopic gastrostomy (Cook Medical). In a similar way as described by other authors ...
TY - JOUR. T1 - Bilobectomy for Bronchogenic Carcinoma. AU - Keller, Steven M.. AU - Kaiser, Larry R.. AU - Martini, Nael. PY - 1988/1/1. Y1 - 1988/1/1. N2 - During a 12-year period, bilobectomy was performed on 166 patients for the treatment of primary lung carcinoma: 108 patients (65%) underwent right upper and middle lobectomy, while 58 patients (35%) underwent right middle and lower lobectomy. Indications for bilobectomy were tumor extending across a fissure (45%), absent fissure (21%), endobronchial tumor (14%), extrinsic tumor or nodal invasion of bronchus intermedius (10%), and vascular invasion (5%). Thirty-one patients (19%) suffered 41 perioperative complications, and 7 patients (4.2%) died. Upper and middle lobectomies were not associated with a significantly different morbidity (p , 0.10) or mortality (p , 0.10) when compared with middle and lower lobectomy. The postoperative chest roentgenograms of all patients demonstrated ipsilateral volume loss, and 31 patients were found to have ...
TY - JOUR. T1 - Natural history of bronchial preinvasive lesions. AU - Ishizumi, Taichiro. AU - McWilliams, Annette. AU - MacAulay, Calum. AU - Gazdar, Adi. AU - Lam, Stephen. PY - 2010/3. Y1 - 2010/3. N2 - Preinvasive bronchial lesions defined as dysplasia and carcinoma in situ (CIS) have been considered as precursors of squamous cell carcinoma of the lung. The risk and rate of progression of preinvasive lesions to invasive squamous cell carcinoma as well as the mechanism of progression or regression are incompletely understood. While the evidence for the multistage, stepwise progression model is weak with relatively few documented lesions that progress through various grades of dysplasia to CIS and then to invasive carcinoma, the concept of field carcinogenesis is strongly supported. The presence of high-grade dysplasia or CIS is a risk marker for lung cancer both in the central airways and peripheral lung. Genetic alterations such as loss of heterozygosity in chromosome 3p or chromosomal ...
Tracheobronchial foreign body (TFB) aspiration is a common occurrence in children compared with adults. Long-standing cases of TFB aspiration during childhood presenting in an adult have rarely been reported. We report the unique case of an endobronchial Playmobil traffic cone that went undetected for 40 years and presented as a suspected bronchogenic carcinoma. This was subsequently removed successfully with flexible bronchoscopy. To our knowledge this is the first case of a TFB that was overlooked this length of time. ...
Purpose: To assess various volume based PET quantification metrics including: metabolic tumor volume (MTV) and total lesion glycolysis (TLG) with different thresholds as well as background activity based PET metrics (Background Subtracted Lesion activity (BSL) and Volume (BSV)) as prognostic markers for progression free and overall survival (PFS, OS) in early stage I and II non-small cell lung cancer (NSCLC) after resection. Patients and Methods: 133 patients received an adequate FDG PET/CT scan prior to surgery between January 2003 and December 2010. All PET activity metrics showed a skewed distribution and were log-transformed before calculating the Pearson correlation coefficients (PCC). Survival tree analysis was used to discriminate between high and low risk patients and to select the most important prognostic markers. Akaike information criterion (AIC) was used to compare two uni-variate models. Results: Within the study time 36 patients died from NSCLC and 26 patients from other causes. ...
The protein encoded by this gene acts as receptor for arginine vasopressin. This receptor belongs to the subfamily of G-protein coupled receptors which includes AVPR1A, V2R and OXT receptors. Its activity is mediated by G proteins which stimulate a phosphatidylinositol-calcium second messenger system. The receptor is primarily located in the anterior pituitary, where it stimulates ACTH release. It is expressed at high levels in ACTH-secreting pituitary adenomas as well as in bronchial carcinoids responsible for the ectopic ACTH syndrome. A spliced antisense transcript of this gene has been reported but its function is not known. [provided by RefSeq, Jul 2008 ...
Co-led by Drs. Olopade (UChicago) and Jagai (UIC). The Air, Water and Soil Pollutants (AWSP) focus group will address exposures that may drive the high rates of diabetes, cardiovascular disease, asthma, chronic obstructive lung disease (COPD) as well as a variety of cancers including lung and bronchial cancer found in Chicago.. While causes for disparities in incidence of these diseases across Chicago communities are multifactorial, disproportionate exposure to pollutants in air, water, soil and workplaces are likely contributors. Of the Top 50 polluters in Cook County in 2015, 60% are located near residences of AAs and Latinos. People living in the Chicago area face some of the nations highest risks for lung disease, cancers and other health problems linked to particulates, metals, and volatile organics from stationary and mobile sources of air pollution. Similarly, water quality in Chicago is a major concern. Members of this AWSP focus group have identified persistent organic pollutants ...

Introduction: Typical and atypical bronchial carcinoids (TBC and ABC) are well-differentiated neuroendocrine neoplasms (NEN). Metastatic BC having low to moderate mitotic count may still be treated with somatostatin analogues and mTOR inhibitors; however, TBC and ABC have been reported to respond very differently to therapy and an effective treatment algorithm is still lacking. TGF-β is known for its ability to activate mTOR pathway and induce epithelial mesenchymal transition, affecting cell pathophysiological capabilities such as proliferation, migration and tissue invasiveness ...

A 55-year-old man was referred to our hospital due to intolerant severe short of breathing and persistent cough for two hours. He had similar attacks in the past two years which were treated with bronchodilators. Computed tomography revealed endobronchial mass, which was endoscopically resected by laser. Histology revealed benign squamous papilloma. In this paper we will deal with the various nonspecific clinical presentations, etiopathology, predisposing factors, and diagnosing tests of these benign tumors, especially the important role of computed tomography.

We placed a DXM-eluting, polyurethane-covered, self-expanding metallic stent (drug stent, DS) and a polyurethane-covered, self-expanding metallic stent (control stent, CS) alternately in each left main bronchus and left lower lobe bronchus in 12 dogs. The stents were 20 mm in diameter and length when fully expanded. The dose of DXM was approximately 36.7 mg in each DS, but was absent in the CS. The dogs were euthanased 1 week ...
The third case of a culturally and histologically proven candidosis of the prostate in the world literature available to us is reported. Autopsy of a 59-year-old man with metastasizing bronchial carcinoma as predisposing primary disease revealed a local candidosis of the prostate in the left lobe of the prostate, without evidence of a Candida sepsis. Parallel and different aspects in comparison with the other two cases are described.

Carcinoid tumors of the lung are a fascinating but uncommon group of pulmonary neoplasms. In the past, these tumors were grouped with benign or less aggressive malignant pulmonary tumors.
Endobronchial cancer are characterized by small size, slow growth and usually misdiagnosed as asthma or chronic bronchitis due to their common symptoms.This research report analyzes this market on the basis of its market segments, major geographies, and current market trends.
For operable patients with NSCLC in whom tumour growth is limited to one lobe, lobectomy is the treatment of choice. Intentionally curative radiotherapy is a good alternative if the surgical risk is determined to be (too) high.. Patients in whom lung function is so limited that lobectomy is not possible may be considered for segment resection (preferred) or wedge excision if complete resection using this method is possible.. In principle, if the lung tumour has spread from one lobe to another, a lobectomy plus a wedge resection of the other lobe should be performed. For central tumours, bilobectomy or pneumonectomy may be an option.. If a conventional lobectomy is not possible due to tumour growth up to or past the level of the bronchial ostium, a sleeve lobectomy is advisable because complete resection is possible with this technique even when lung function precludes pneumonectomy.. A sleeve resection of the pulmonary artery should be performed only if the patient cannot tolerate pneumonectomy ...
