Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
Surgical removal of the pancreas. (Dorland, 28th ed)
Death resulting from the presence of a disease in an individual, as shown by a single case report or a limited number of patients. This should be differentiated from DEATH, the physiological cessation of life and from MORTALITY, an epidemiological or statistical concept.

A malignant neoplasm characterized by the formation of numerous, irregular, finger-like projections of fibrous stroma that is covered with a surface layer of neoplastic epithelial cells. (Stedman, 25th ed)
A family of small, non-enveloped DNA viruses infecting birds and most mammals, especially humans. They are grouped into multiple genera, but the viruses are highly host-species specific and tissue-restricted. They are commonly divided into hundreds of papillomavirus "types", each with specific gene function and gene control regions, despite sequence homology. Human papillomaviruses are found in the genera ALPHAPAPILLOMAVIRUS; BETAPAPILLOMAVIRUS; GAMMAPAPILLOMAVIRUS; and MUPAPILLOMAVIRUS.

Two major conformational groups have been characterized, alpha-keratin, whose peptide backbone forms a coiled-coil alpha helical structure consisting of TYPE I KERATIN and a TYPE II KERATIN, and beta-keratin, whose backbone forms a zigzag or pleated sheet structure. alpha-Keratins have been classified into at least 20 subtypes. In addition multiple isoforms of subtypes have been found which may be due to GENE DUPLICATION.
A malignant skin neoplasm that seldom metastasizes but has potentialities for local invasion and destruction. Clinically it is divided into types: nodular, cicatricial, morphaic, and erythematoid (pagetoid). They develop on hair-bearing skin, most commonly on sun-exposed areas. Approximately 85% are found on the head and neck area and the remaining 15% on the trunk and limbs. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1471)

Human papillomavirus DNA in adenosquamous carcinoma of the lung. (1/236)

AIM: To investigate the presence of human papillomavirus (HPV) DNA in adenosquamous carcinoma of the lung--which is relatively common in Okinawa but not in mainland Japan--and examine its histological features. METHODS: Of 207 cases where primary lung cancers were surgically removed between January 1995 and June 1997 in Okinawa, 23 were adenosquamous carcinoma. HPV was detected by non-isotopic in situ hybridisation (NISH) and polymerase chain reaction (PCR) amplification with primers specific for E6 and E7 regions of the HPV genome. PCR products were analysed by Southern blotting. Immunohistochemical determination of high molecular weight cytokeratin (HMC) and involucrin was also carried out. RESULTS: 18 cases were positive for HPV DNA by PCR and NISH. HPV types 6, 11, 16, and 18 were found. Seven cases were dual positive for different types of HPV. Using NISH, HPV was also found in the squamous cell components and in neighbouring enlarged adenocarcinoma cells. The HMC and involucrin were demonstrated immunohistochemically in the same areas. CONCLUSIONS: HPV DNA was found in a high proportion (78.3%) of adenosquamous carcinomas in Okinawa, a region where HPV has previously been shown to be prevalent in squamous cell carcinoma of the lung. The adenocarcinoma cells adjacent to the squamous cell carcinoma component were enlarged and positive for HPV, HMC, and involucrin. This is thought to indicate the transition from adenocarcinoma to squamous cell carcinoma.  (+info)

Randomized comparison of fluorouracil plus cisplatin versus hydroxyurea as an adjunct to radiation therapy in stage IIB-IVA carcinoma of the cervix with negative para-aortic lymph nodes: a Gynecologic Oncology Group and Southwest Oncology Group study. (2/236)

PURPOSE: In 1986, a protocol comparing primary radiation therapy (RT) plus hydroxyurea (HU) to irradiation plus fluorouracil (5-FU) and cisplatin (CF) was activated by the Gynecologic Oncology Group (GOG) for the treatment of patients with locally advanced cervical carcinoma. The goals were to determine the superior chemoradiation regimen and to quantitate the relative toxicities. METHODS: All patients had biopsy-proven invasive squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma of the uterine cervix. Patients underwent standard clinical staging studies and their tumors were found to be International Federation of Gynaecology and Obstetrics stages IIB, III, or IVA. Negative cytologic washings and para-aortic lymph nodes were required for entry. Patients were randomized to receive either standard whole pelvic RT with concurrent 5-FU infusion and bolus CF or the same RT plus oral HU. RESULTS: Of 388 randomized patients, 368 were eligible; 177 were randomized to CF and 191 to HU. Adverse effects were predominantly hematologic or gastrointestinal in both regimens. Severe or life-threatening leukopenia was more common in the HU group (24%) than in the CF group (4%). The difference in progression-free survival (PFS) was statistically significant in favor of the CF group (P = .033). The sites of progression in the two treatment groups were not substantially different. Survival was significantly better for the patients randomized to CF (P = .018). CONCLUSION: This study demonstrates that for patients with locally advanced carcinoma of the cervix, the combination of 5-FU and CF with RT offers patients better PFS and overall survival than HU, and with manageable toxicity.  (+info)

Haematogenous cytokeratin 20 mRNA as a predictive marker for recurrence in oral cancer patients. (3/236)

We examined the expression of cytokeratin 20 (CK20) mRNA in the peripheral blood of oral squamous cell carcinoma (SCC) patients by reverse transcriptase polymerase chain reaction (RT-PCR). Eleven out of 12 oral SCC patients showed positive RT-PCR results. However, there is no clear relationship between the haematogenous CK20 mRNA and the metastasis. After initial treatment, all of the tumour-free survivors tested showed negative RT-PCR results. CK20 mRNA in peripheral blood can be used as a marker for tumour recurrence but not not for metastasis in oral SCC patients.  (+info)

A population-based survey of the management of women with cancer of the cervix. (4/236)

The aim of this study was to investigate the influence of diagnostic throughput on survival outcome for women with cancer of the cervix. We conducted a case note review of 359 women in Lancashire and Greater Manchester diagnosed with cancer of the cervix during 1990, identified from records held by the North Western Regional Cancer Registry. Univariate and multivariate survival analyses were undertaken to investigate the influence on survival of woman, disease and treatment related factors. Following adjustment for woman- and disease-related factors there was no evidence of a statistically significant association between diagnostic throughput and survival. The findings of this study do not support the need for any change in the referral patterns to gynaecologists of women with symptoms suggestive of cancer of the cervix.  (+info)

Overexpression of cyclooxygenase-2 in carcinoma of the pancreas. (5/236)

The level of cyclooxygenase (COX)-2 has been investigated recently in various human carcinomas. In the present study, we examined the distribution and extent of COX-2 protein in human pancreatic tumors using immunohistochemistry. A strong expression of COX-2 protein was present in 23 of 52 (44%) pancreatic carcinomas, a moderate expression was present in 24 of 52 (46%) pancreatic carcinomas, and a weak expression was present in 5 of 52 (10%) pancreatic carcinomas. In contrast, benign tumors showed weak expression or no expression of COX-2, and only islet cells displayed COX-2 expression in normal pancreatic tissues. Overexpression of COX-2 in carcinoma tissues was also confirmed by Western blot analysis. Furthermore, consistent with the results at protein levels, reverse transcription-PCR analyses indicated that COX-2 mRNA was overexpressed in 7 of 13 (54%) carcinomas, but in none of 3 benign tumors. Our findings suggest that COX-2 inhibitors might be potentially effective against pancreatic carcinomas and that COX-2 may be involved in certain biological processes in pancreatic islets.  (+info)

Adenosquamous carcinoma of the prostate. (6/236)

An unusual adenosquamous carcinoma originating in the prostate of a 73-year-old man is described. The histological finding showed a well differentiated squamous cell carcinoma admixed in an adenocarcinomatous area. A transitional area of 2 carcinomatous elements was also noted. Seven months prior to the development of this lesion, a diagnosis of adenocarcinoma had been established by transurethral resection of the prostate and the patient had been treated with bilateral orchiectomy. This is the first case of adenosquamous carcinoma of the prostate reported in Korea. The pathogenesis and previous reports of this lesion will be discussed.  (+info)

Carbonic anhydrase IX antigen differentiates between preneoplastic malignant lesions in non-small cell lung carcinoma. (7/236)

The MaTu interval (MN)/carbonic anhydrase (CA) IX tumour-associated antigen is a protein that is normally expressed in the gut and belongs to the carbonic anhydrase enzyme family (CA IX). It has been detected in tumour cell lines and in some solid tumours including cervical, oesophageal and clear cell renal carcinoma. This study determined MN/CA IX expression in 65 primary non-small cell lung cancer resected with curative intent and in 38 bronchial preneoplastic lesions, carcinoma in situ or microinvasive carcinoma as well as in normal bronchial tissue. The presence of MN/CA IX was detected using immunohistochemistry and Western blot analysis, whenever frozen material was available. Immunostaining was positive in 52/65 (80%) of the tumour samples. The staining was more often focal than diffuse. The percentage of stained cells in positive tumours was highly variable, ranging 1-85%. The pattern of immunostaining was predominantly cytoplasmic with a membranous reinforcement (87%). The intensity was mainly strong (69%). The presence of the protein in the tumour was confirmed by Western blot analysis in the eight samples tested. All the morphologically normal epithelia, except in close vicinity of tumours in some cases, as well as the preneoplastic bronchial lesions (basal cell hyperplasia, metaplasia and dysplasia) were immunonegative for MN/CA IX expression. In contrast, carcinoma in situ and microinvasive epithelioma showed the presence of MN-immunopositive tumoural cells in 5/7 and 4/5 of the samples, respectively. These data suggest that MN/CA IX is a useful marker for the differentiation between preneoplastic lesions and bronchial non-small cell lung cancer in the lung.  (+info)

Inhibitory effects of combined administration of antibiotics and anti-inflammatory drugs on lung tumor development initiated by N-nitrosobis(2-hydroxypropyl)amine in rats. (8/236)

The effects of antibiotics and anti-inflammatory drugs on the promotion stage of lung carcinogenesis initiated with N-nitrosobis(2-hydroxypropyl)amine (BHP) in rats were investigated in two experiments with a similar protocol. In experiment 1, rats received tap water containing 2000 p.p.m. BHP for 12 weeks followed by basal diet or basal diet containing 0.02% erythromycin (EM), 0. 04% ampicillin (ABPC), 1.5% sho-saiko-to, 0.02% EM plus 1.5% sho-saiko-to or 0.04% ABPC plus 1.5% sho-saiko-to for 8 weeks after BHP administration. The development of adenocarcinomas (AC), squamous cell carcinomas (SqC) and adenosquamous carcinomas (ASqC) was completely inhibited in rats given ABPC plus sho-saiko-to and the numbers of lung lesions including alveolar hyperplasias, adenomas and carcinomas were decreased in rats given EM plus sho-saiko-to or ABPC plus sho-saiko-to. Neutrophil and macrophage infiltration into alveolar spaces of the lung were also markedly suppressed. In experiment 2, rats received BHP in the same manner as in experiment 1 and basal diet or basal diet containing 0.04% ABPC, 0.006% piroxicam, 0.04% ABPC plus 0.006% piroxicam and 0.04% ABPC plus 0.75% ougon for 8 weeks. The incidence and number of carcinomas, including ACs, SqCs and ASqCs were decreased in rats given ABPC plus piroxicam or ABPC plus ougon. Bacteria, mainly Escherichia coli, were detected in broncho-alveolar lavage of rats receiving BHP. The results suggest that chronic inflammation might be involved in the progression of lung carcinogenesis by BHP in rats and its suppression may therefore be useful as a chemopreventive strategy in lung cancer clinics.  (+info)

Adenosquamous carcinoma is a rare type of cancer that contains two types of cells: glandular (adeno) and squamous. This mixed composition leads to a unique microscopic appearance and more aggressive behavior compared to other types of carcinomas. Adenosquamous carcinoma can occur in various organs, such as the lung, pancreas, cervix, and skin.

The glandular (adeno) component is made up of columnar epithelial cells that form glands or tubular structures. These cells produce mucus or other secretions. The squamous component consists of flat, scale-like cells that resemble the cells found in the outer layer of the skin.

The presence of both adeno and squamous components in a single tumor can lead to more rapid growth, increased likelihood of metastasis (spreading to other parts of the body), and poorer prognosis compared to carcinomas with only one cell type. Treatment typically involves surgical resection, radiation therapy, chemotherapy, or a combination of these approaches, depending on the location and stage of the cancer.

Carcinoma is a type of cancer that develops from epithelial cells, which are the cells that line the inner and outer surfaces of the body. These cells cover organs, glands, and other structures within the body. Carcinomas can occur in various parts of the body, including the skin, lungs, breasts, prostate, colon, and pancreas. They are often characterized by the uncontrolled growth and division of abnormal cells that can invade surrounding tissues and spread to other parts of the body through a process called metastasis. Carcinomas can be further classified based on their appearance under a microscope, such as adenocarcinoma, squamous cell carcinoma, and basal cell carcinoma.

Squamous cell carcinoma is a type of skin cancer that begins in the squamous cells, which are flat, thin cells that form the outer layer of the skin (epidermis). It commonly occurs on sun-exposed areas such as the face, ears, lips, and backs of the hands. Squamous cell carcinoma can also develop in other areas of the body including the mouth, lungs, and cervix.

This type of cancer usually develops slowly and may appear as a rough or scaly patch of skin, a red, firm nodule, or a sore or ulcer that doesn't heal. While squamous cell carcinoma is not as aggressive as some other types of cancer, it can metastasize (spread) to other parts of the body if left untreated, making early detection and treatment important.

Risk factors for developing squamous cell carcinoma include prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds, fair skin, a history of sunburns, a weakened immune system, and older age. Prevention measures include protecting your skin from the sun by wearing protective clothing, using a broad-spectrum sunscreen with an SPF of at least 30, avoiding tanning beds, and getting regular skin examinations.

Adenocarcinoma is a type of cancer that arises from glandular epithelial cells. These cells line the inside of many internal organs, including the breasts, prostate, colon, and lungs. Adenocarcinomas can occur in any of these organs, as well as in other locations where glands are present.

The term "adenocarcinoma" is used to describe a cancer that has features of glandular tissue, such as mucus-secreting cells or cells that produce hormones. These cancers often form glandular structures within the tumor mass and may produce mucus or other substances.

Adenocarcinomas are typically slow-growing and tend to spread (metastasize) to other parts of the body through the lymphatic system or bloodstream. They can be treated with surgery, radiation therapy, chemotherapy, targeted therapy, or a combination of these treatments. The prognosis for adenocarcinoma depends on several factors, including the location and stage of the cancer, as well as the patient's overall health and age.

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer in adults. It originates from the hepatocytes, which are the main functional cells of the liver. This type of cancer is often associated with chronic liver diseases such as cirrhosis caused by hepatitis B or C virus infection, alcohol abuse, non-alcoholic fatty liver disease (NAFLD), and aflatoxin exposure.

The symptoms of HCC can vary but may include unexplained weight loss, lack of appetite, abdominal pain or swelling, jaundice, and fatigue. The diagnosis of HCC typically involves imaging tests such as ultrasound, CT scan, or MRI, as well as blood tests to measure alpha-fetoprotein (AFP) levels. Treatment options for Hepatocellular carcinoma depend on the stage and extent of the cancer, as well as the patient's overall health and liver function. Treatment options may include surgery, radiation therapy, chemotherapy, targeted therapy, or liver transplantation.

Uterine cervical neoplasms, also known as cervical cancer or cervical dysplasia, refer to abnormal growths or lesions on the lining of the cervix that have the potential to become cancerous. These growths are usually caused by human papillomavirus (HPV) infection and can be detected through routine Pap smears.

Cervical neoplasms are classified into different grades based on their level of severity, ranging from mild dysplasia (CIN I) to severe dysplasia or carcinoma in situ (CIN III). In some cases, cervical neoplasms may progress to invasive cancer if left untreated.

Risk factors for developing cervical neoplasms include early sexual activity, multiple sexual partners, smoking, and a weakened immune system. Regular Pap smears and HPV testing are recommended for early detection and prevention of cervical cancer.

Lung neoplasms refer to abnormal growths or tumors in the lung tissue. These tumors can be benign (non-cancerous) or malignant (cancerous). Malignant lung neoplasms are further classified into two main types: small cell lung carcinoma and non-small cell lung carcinoma. Lung neoplasms can cause symptoms such as cough, chest pain, shortness of breath, and weight loss. They are often caused by smoking or exposure to secondhand smoke, but can also occur due to genetic factors, radiation exposure, and other environmental carcinogens. Early detection and treatment of lung neoplasms is crucial for improving outcomes and survival rates.

Plutonium is not a medical term, but it is a chemical element with the symbol Pu and atomic number 94. It is a dense, silvery-red, transuranic radioactive metal that occurs in minute quantities naturally as an intermediate product of uranium decay, or can be produced by neutron capture in uranium-238.

Plutonium is highly toxic and radioactive, and it has been classified as a Category II carcinogen by the International Agency for Research on Cancer (IARC). It is mainly used in the production of nuclear weapons and as fuel in nuclear reactors. Medical uses of plutonium are limited due to its high radioactivity and toxicity.

In medicine, plutonium-210 has been used in some cancer therapies, such as brachytherapy, where a small amount of the isotope is implanted directly into the tumor. However, due to its high radioactivity and potential for causing radiation damage to surrounding tissues, its use in medicine is highly regulated and relatively rare.

Lacrimal apparatus diseases refer to conditions that affect the structure and function of the lacrimal system, which is responsible for producing, storing, and draining tears. The lacrimal apparatus includes the lacrimal glands, lacrimal canaliculi, lacrimal sac, and nasolacrimal duct.

Diseases of the lacrimal apparatus can cause a range of symptoms, including watery eyes, redness, pain, swelling, and discharge. Some common conditions that affect the lacrimal apparatus include:

1. Dry eye syndrome: A condition in which the lacrimal glands do not produce enough tears or the tears are of poor quality, leading to dryness, irritation, and inflammation of the eyes.
2. Dacryocystitis: An infection of the lacrimal sac that can cause pain, swelling, redness, and discharge from the eye.
3. Nasolacrimal duct obstruction: A blockage in the nasolacrimal duct that can cause watery eyes, discharge, and recurrent infections.
4. Epiphora: Excessive tearing or watering of the eyes due to overflow of tears from the eye because of blocked tear ducts or increased production of tears.
5. Canaliculitis: An infection of the lacrimal canaliculi that can cause swelling, redness, and discharge from the eye.
6. Lacrimal gland tumors: Rare tumors that can affect the lacrimal glands and cause symptoms such as pain, swelling, and protrusion of the eyeball.

Treatment for lacrimal apparatus diseases depends on the specific condition and its severity. Treatment options may include medications, surgery, or a combination of both.

Gallbladder neoplasms refer to abnormal growths in the tissue of the gallbladder, which can be benign or malignant. Benign neoplasms are non-cancerous and typically do not spread to other parts of the body. Malignant neoplasms, also known as gallbladder cancer, can invade nearby tissues and organs and may metastasize (spread) to distant parts of the body. Gallbladder neoplasms can cause symptoms such as abdominal pain, jaundice, and nausea, but they are often asymptomatic until they have advanced to an advanced stage. The exact causes of gallbladder neoplasms are not fully understood, but risk factors include gallstones, chronic inflammation of the gallbladder, and certain inherited genetic conditions.

Immunohistochemistry (IHC) is a technique used in pathology and laboratory medicine to identify specific proteins or antigens in tissue sections. It combines the principles of immunology and histology to detect the presence and location of these target molecules within cells and tissues. This technique utilizes antibodies that are specific to the protein or antigen of interest, which are then tagged with a detection system such as a chromogen or fluorophore. The stained tissue sections can be examined under a microscope, allowing for the visualization and analysis of the distribution and expression patterns of the target molecule in the context of the tissue architecture. Immunohistochemistry is widely used in diagnostic pathology to help identify various diseases, including cancer, infectious diseases, and immune-mediated disorders.

Duodenogastric reflux (DGR) is a medical condition in which the contents of the duodenum, the first part of the small intestine, flow backward into the stomach. This occurs when the pyloric sphincter, a muscle that separates the stomach and duodenum, fails to function properly, allowing the reflux of duodenal juice into the stomach.

Duodenogastric refluxate typically contains bile acids, digestive enzymes, and other stomach-irritating substances. Chronic DGR can lead to gastritis (inflammation of the stomach lining), ulcers, and other gastrointestinal complications. Symptoms may include abdominal pain, bloating, nausea, vomiting, heartburn, and indigestion. Treatment usually involves medications that reduce acid production or neutralize stomach acid, as well as lifestyle modifications to minimize reflux triggers.

Carcinoma in situ is a medical term used to describe the earliest stage of cancer, specifically a type of cancer that begins in the epithelial tissue, which is the tissue that lines the outer surfaces of organs and body structures. In this stage, the cancer cells are confined to the layer of cells where they first developed and have not spread beyond that layer into the surrounding tissues or organs.

Carcinoma in situ can occur in various parts of the body, including the skin, cervix, breast, lung, prostate, bladder, and other areas. It is often detected through routine screening tests, such as Pap smears for cervical cancer or mammograms for breast cancer.

While carcinoma in situ is not invasive, it can still be a serious condition because it has the potential to develop into an invasive cancer if left untreated. Treatment options for carcinoma in situ may include surgery, radiation therapy, or other forms of treatment, depending on the location and type of cancer. It is important to consult with a healthcare provider to determine the best course of action for each individual case.

Pancreatic neoplasms refer to abnormal growths in the pancreas that can be benign or malignant. The pancreas is a gland located behind the stomach that produces hormones and digestive enzymes. Pancreatic neoplasms can interfere with the normal functioning of the pancreas, leading to various health complications.

Benign pancreatic neoplasms are non-cancerous growths that do not spread to other parts of the body. They are usually removed through surgery to prevent any potential complications, such as blocking the bile duct or causing pain.

Malignant pancreatic neoplasms, also known as pancreatic cancer, are cancerous growths that can invade and destroy surrounding tissues and organs. They can also spread (metastasize) to other parts of the body, such as the liver, lungs, or bones. Pancreatic cancer is often aggressive and difficult to treat, with a poor prognosis.

There are several types of pancreatic neoplasms, including adenocarcinomas, neuroendocrine tumors, solid pseudopapillary neoplasms, and cystic neoplasms. The specific type of neoplasm is determined through various diagnostic tests, such as imaging studies, biopsies, and blood tests. Treatment options depend on the type, stage, and location of the neoplasm, as well as the patient's overall health and preferences.

A pancreatectomy is a surgical procedure in which all or part of the pancreas is removed. There are several types of pancreatectomies, including:

* **Total pancreatectomy:** Removal of the entire pancreas, as well as the spleen and nearby lymph nodes. This type of pancreatectomy is usually done for patients with cancer that has spread throughout the pancreas or for those who have had multiple surgeries to remove pancreatic tumors.
* **Distal pancreatectomy:** Removal of the body and tail of the pancreas, as well as nearby lymph nodes. This type of pancreatectomy is often done for patients with tumors in the body or tail of the pancreas.
* **Partial (or segmental) pancreatectomy:** Removal of a portion of the head or body of the pancreas, as well as nearby lymph nodes. This type of pancreatectomy is often done for patients with tumors in the head or body of the pancreas that can be removed without removing the entire organ.
* **Pylorus-preserving pancreaticoduodenectomy (PPPD):** A type of surgery used to treat tumors in the head of the pancreas, as well as other conditions such as chronic pancreatitis. In this procedure, the head of the pancreas, duodenum, gallbladder, and bile duct are removed, but the stomach and lower portion of the esophagus (pylorus) are left in place.

After a pancreatectomy, patients may experience problems with digestion and blood sugar regulation, as the pancreas plays an important role in these functions. Patients may need to take enzyme supplements to help with digestion and may require insulin therapy to manage their blood sugar levels.

A fatal outcome is a term used in medical context to describe a situation where a disease, injury, or illness results in the death of an individual. It is the most severe and unfortunate possible outcome of any medical condition, and is often used as a measure of the severity and prognosis of various diseases and injuries. In clinical trials and research, fatal outcome may be used as an endpoint to evaluate the effectiveness and safety of different treatments or interventions.

Prognosis is a medical term that refers to the prediction of the likely outcome or course of a disease, including the chances of recovery or recurrence, based on the patient's symptoms, medical history, physical examination, and diagnostic tests. It is an important aspect of clinical decision-making and patient communication, as it helps doctors and patients make informed decisions about treatment options, set realistic expectations, and plan for future care.

Prognosis can be expressed in various ways, such as percentages, categories (e.g., good, fair, poor), or survival rates, depending on the nature of the disease and the available evidence. However, it is important to note that prognosis is not an exact science and may vary depending on individual factors, such as age, overall health status, and response to treatment. Therefore, it should be used as a guide rather than a definitive forecast.

Neoplasm staging is a systematic process used in medicine to describe the extent of spread of a cancer, including the size and location of the original (primary) tumor and whether it has metastasized (spread) to other parts of the body. The most widely accepted system for this purpose is the TNM classification system developed by the American Joint Committee on Cancer (AJCC) and the Union for International Cancer Control (UICC).

In this system, T stands for tumor, and it describes the size and extent of the primary tumor. N stands for nodes, and it indicates whether the cancer has spread to nearby lymph nodes. M stands for metastasis, and it shows whether the cancer has spread to distant parts of the body.

Each letter is followed by a number that provides more details about the extent of the disease. For example, a T1N0M0 cancer means that the primary tumor is small and has not spread to nearby lymph nodes or distant sites. The higher the numbers, the more advanced the cancer.

Staging helps doctors determine the most appropriate treatment for each patient and estimate the patient's prognosis. It is an essential tool for communication among members of the healthcare team and for comparing outcomes of treatments in clinical trials.

Tumor markers are substances that can be found in the body and their presence can indicate the presence of certain types of cancer or other conditions. Biological tumor markers refer to those substances that are produced by cancer cells or by other cells in response to cancer or certain benign (non-cancerous) conditions. These markers can be found in various bodily fluids such as blood, urine, or tissue samples.

Examples of biological tumor markers include:

1. Proteins: Some tumor markers are proteins that are produced by cancer cells or by other cells in response to the presence of cancer. For example, prostate-specific antigen (PSA) is a protein produced by normal prostate cells and in higher amounts by prostate cancer cells.
2. Genetic material: Tumor markers can also include genetic material such as DNA, RNA, or microRNA that are shed by cancer cells into bodily fluids. For example, circulating tumor DNA (ctDNA) is genetic material from cancer cells that can be found in the bloodstream.
3. Metabolites: Tumor markers can also include metabolic products produced by cancer cells or by other cells in response to cancer. For example, lactate dehydrogenase (LDH) is an enzyme that is released into the bloodstream when cancer cells break down glucose for energy.

It's important to note that tumor markers are not specific to cancer and can be elevated in non-cancerous conditions as well. Therefore, they should not be used alone to diagnose cancer but rather as a tool in conjunction with other diagnostic tests and clinical evaluations.

Carcinoma, papillary is a type of cancer that begins in the cells that line the glandular structures or the lining of organs. In a papillary carcinoma, the cancerous cells grow and form small finger-like projections, called papillae, within the tumor. This type of cancer most commonly occurs in the thyroid gland, but can also be found in other organs such as the lung, breast, and kidney. Papillary carcinoma of the thyroid gland is usually slow-growing and has a good prognosis, especially when it is diagnosed at an early stage.

Papillomaviridae is a family of small, non-enveloped DNA viruses that primarily infect the epithelial cells of mammals, birds, and reptiles. The name "papillomavirus" comes from the Latin word "papilla," which means nipple or small projection, reflecting the characteristic wart-like growths (papillomas) that these viruses can cause in infected host tissues.

The family Papillomaviridae includes more than 200 distinct papillomavirus types, with each type being defined by its specific DNA sequence. Human papillomaviruses (HPVs), which are the most well-studied members of this family, are associated with a range of diseases, from benign warts and lesions to malignant cancers such as cervical, anal, penile, vulvar, and oropharyngeal cancers.

Papillomaviruses have a circular, double-stranded DNA genome that is approximately 8 kbp in size. The viral genome encodes several early (E) proteins involved in viral replication and oncogenesis, as well as late (L) proteins that form the viral capsid. The life cycle of papillomaviruses is tightly linked to the differentiation program of their host epithelial cells, with productive infection occurring primarily in the differentiated layers of the epithelium.

In summary, Papillomaviridae is a family of DNA viruses that infect epithelial cells and can cause a variety of benign and malignant diseases. Human papillomaviruses are a significant public health concern due to their association with several cancer types.

Medical survival rate is a statistical measure used to determine the percentage of patients who are still alive for a specific period of time after their diagnosis or treatment for a certain condition or disease. It is often expressed as a five-year survival rate, which refers to the proportion of people who are alive five years after their diagnosis. Survival rates can be affected by many factors, including the stage of the disease at diagnosis, the patient's age and overall health, the effectiveness of treatment, and other health conditions that the patient may have. It is important to note that survival rates are statistical estimates and do not necessarily predict an individual patient's prognosis.

Liver neoplasms refer to abnormal growths in the liver that can be benign or malignant. Benign liver neoplasms are non-cancerous tumors that do not spread to other parts of the body, while malignant liver neoplasms are cancerous tumors that can invade and destroy surrounding tissue and spread to other organs.

Liver neoplasms can be primary, meaning they originate in the liver, or secondary, meaning they have metastasized (spread) to the liver from another part of the body. Primary liver neoplasms can be further classified into different types based on their cell of origin and behavior, including hepatocellular carcinoma, cholangiocarcinoma, and hepatic hemangioma.

The diagnosis of liver neoplasms typically involves a combination of imaging studies, such as ultrasound, CT scan, or MRI, and biopsy to confirm the type and stage of the tumor. Treatment options depend on the type and extent of the neoplasm and may include surgery, radiation therapy, chemotherapy, or liver transplantation.

Microdissection is a surgical technique that involves the use of a microscope to allow for precise, minimalistic dissection of tissue. It is often used in research and clinical settings to isolate specific cells, tissues or structures while minimizing damage to surrounding areas. This technique can be performed using various methods such as laser capture microdissection (LCM) or manual microdissection with microsurgical tools. The size and scale of the dissection required will determine the specific method used. In general, microdissection allows for the examination and analysis of very small and delicate structures that would otherwise be difficult to access and study.

Carcinoma, ductal, breast is a type of breast cancer that begins in the milk ducts (the tubes that carry milk from the lobules of the breast to the nipple). It is called "ductal" because it starts in the cells that line the milk ducts. Ductal carcinoma can be further classified as either non-invasive or invasive, based on whether the cancer cells are confined to the ducts or have spread beyond them into the surrounding breast tissue.

Non-invasive ductal carcinoma (also known as intraductal carcinoma or ductal carcinoma in situ) is a condition where abnormal cells have been found in the lining of the milk ducts, but they have not spread outside of the ducts. These cells have the potential to become invasive and spread to other parts of the breast or body if left untreated.

Invasive ductal carcinoma (IDC) is a type of breast cancer that starts in a milk duct and then grows into the surrounding breast tissue. From there, it can spread to other parts of the body through the bloodstream and lymphatic system. IDC is the most common form of breast cancer, accounting for about 80% of all cases.

Symptoms of ductal carcinoma may include a lump or thickening in the breast, changes in the size or shape of the breast, dimpling or puckering of the skin on the breast, nipple discharge (especially if it is clear or bloody), and/or redness or scaling of the nipple or breast skin. However, many cases of ductal carcinoma are detected through mammography before any symptoms develop.

Treatment for ductal carcinoma depends on several factors, including the stage and grade of the cancer, as well as the patient's overall health and personal preferences. Treatment options may include surgery (such as a lumpectomy or mastectomy), radiation therapy, chemotherapy, hormone therapy, and/or targeted therapies.

Keratins are a type of fibrous structural proteins that constitute the main component of the integumentary system, which includes the hair, nails, and skin of vertebrates. They are also found in other tissues such as horns, hooves, feathers, and reptilian scales. Keratins are insoluble proteins that provide strength, rigidity, and protection to these structures.

Keratins are classified into two types: soft keratins (Type I) and hard keratins (Type II). Soft keratins are found in the skin and simple epithelial tissues, while hard keratins are present in structures like hair, nails, horns, and hooves.

Keratin proteins have a complex structure consisting of several domains, including an alpha-helical domain, beta-pleated sheet domain, and a non-repetitive domain. These domains provide keratin with its unique properties, such as resistance to heat, chemicals, and mechanical stress.

In summary, keratins are fibrous structural proteins that play a crucial role in providing strength, rigidity, and protection to various tissues in the body.

Carcinoma, basal cell is a type of skin cancer that arises from the basal cells, which are located in the lower part of the epidermis (the outermost layer of the skin). It is also known as basal cell carcinoma (BCC) and is the most common form of skin cancer.

BCC typically appears as a small, shiny, pearly bump or nodule on the skin, often in sun-exposed areas such as the face, ears, neck, hands, and arms. It may also appear as a scar-like area that is white, yellow, or waxy. BCCs are usually slow growing and rarely spread (metastasize) to other parts of the body. However, they can be locally invasive and destroy surrounding tissue if left untreated.

The exact cause of BCC is not known, but it is thought to be related to a combination of genetic and environmental factors, including exposure to ultraviolet (UV) radiation from the sun or tanning beds. People with fair skin, light hair, and blue or green eyes are at increased risk of developing BCC.

Treatment for BCC typically involves surgical removal of the tumor, along with a margin of healthy tissue. Other treatment options may include radiation therapy, topical chemotherapy, or photodynamic therapy. Prevention measures include protecting your skin from UV radiation by wearing protective clothing, using sunscreen, and avoiding tanning beds.

Carcinoma, non-small-cell lung (NSCLC) is a type of lung cancer that includes several subtypes of malignant tumors arising from the epithelial cells of the lung. These subtypes are classified based on the appearance of the cancer cells under a microscope and include adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. NSCLC accounts for about 85% of all lung cancers and tends to grow and spread more slowly than small-cell lung cancer (SCLC).

NSCLC is often asymptomatic in its early stages, but as the tumor grows, symptoms such as coughing, chest pain, shortness of breath, hoarseness, and weight loss may develop. Treatment options for NSCLC depend on the stage and location of the cancer, as well as the patient's overall health and lung function. Common treatments include surgery, radiation therapy, chemotherapy, targeted therapy, or a combination of these approaches.

Lymphatic metastasis is the spread of cancer cells from a primary tumor to distant lymph nodes through the lymphatic system. It occurs when malignant cells break away from the original tumor, enter the lymphatic vessels, and travel to nearby or remote lymph nodes. Once there, these cancer cells can multiply and form new tumors, leading to further progression of the disease. Lymphatic metastasis is a common way for many types of cancer to spread and can have significant implications for prognosis and treatment strategies.

Retrospective studies, also known as retrospective research or looking back studies, are a type of observational study that examines data from the past to draw conclusions about possible causal relationships between risk factors and outcomes. In these studies, researchers analyze existing records, medical charts, or previously collected data to test a hypothesis or answer a specific research question.

Retrospective studies can be useful for generating hypotheses and identifying trends, but they have limitations compared to prospective studies, which follow participants forward in time from exposure to outcome. Retrospective studies are subject to biases such as recall bias, selection bias, and information bias, which can affect the validity of the results. Therefore, retrospective studies should be interpreted with caution and used primarily to generate hypotheses for further testing in prospective studies.

Papillomavirus infections are a group of diseases caused by various types of human papillomaviruses (HPVs). These viruses infect the skin and mucous membranes, and can cause benign growths such as warts or papillomas, as well as malignant growths like cervical cancer.

There are more than 100 different types of HPVs, and they can be classified into low-risk and high-risk types based on their potential to cause cancer. Low-risk HPV types, such as HPV-6 and HPV-11, commonly cause benign genital warts and respiratory papillomas. High-risk HPV types, such as HPV-16 and HPV-18, are associated with an increased risk of developing cancer, including cervical, anal, penile, vulvar, and oropharyngeal cancers.

HPV infections are typically transmitted through sexual contact, and most sexually active individuals will acquire at least one HPV infection during their lifetime. In many cases, the immune system is able to clear the virus without any symptoms or long-term consequences. However, persistent high-risk HPV infections can lead to the development of cancer over time.

Prevention measures for HPV infections include vaccination against high-risk HPV types, safe sex practices, and regular screening for cervical cancer in women. The HPV vaccine is recommended for both boys and girls aged 11-12 years old, and can also be given to older individuals up to age 45 who have not previously been vaccinated or who have not completed the full series of shots.

Pancreaticoduodenectomy, also known as the Whipple procedure, is a complex surgical operation that involves the removal of the head of the pancreas, the duodenum (the first part of the small intestine), the gallbladder, and the distal common bile duct. In some cases, a portion of the stomach may also be removed. The remaining parts of the pancreas, bile duct, and intestines are then reconnected to allow for the digestion of food and drainage of bile.

This procedure is typically performed as a treatment for various conditions affecting the pancreas, such as tumors (including pancreatic cancer), chronic pancreatitis, or traumatic injuries. It is a major surgical operation that requires significant expertise and experience to perform safely and effectively.

The Epidermal Growth Factor Receptor (EGFR) is a type of receptor found on the surface of many cells in the body, including those of the epidermis or outer layer of the skin. It is a transmembrane protein that has an extracellular ligand-binding domain and an intracellular tyrosine kinase domain.

EGFR plays a crucial role in various cellular processes such as proliferation, differentiation, migration, and survival. When EGF (Epidermal Growth Factor) or other ligands bind to the extracellular domain of EGFR, it causes the receptor to dimerize and activate its intrinsic tyrosine kinase activity. This leads to the autophosphorylation of specific tyrosine residues on the receptor, which in turn recruits and activates various downstream signaling molecules, resulting in a cascade of intracellular signaling events that ultimately regulate gene expression and cell behavior.

Abnormal activation of EGFR has been implicated in several human diseases, including cancer. Overexpression or mutation of EGFR can lead to uncontrolled cell growth and division, angiogenesis, and metastasis, making it an important target for cancer therapy.

A mutation is a permanent change in the DNA sequence of an organism's genome. Mutations can occur spontaneously or be caused by environmental factors such as exposure to radiation, chemicals, or viruses. They may have various effects on the organism, ranging from benign to harmful, depending on where they occur and whether they alter the function of essential proteins. In some cases, mutations can increase an individual's susceptibility to certain diseases or disorders, while in others, they may confer a survival advantage. Mutations are the driving force behind evolution, as they introduce new genetic variability into populations, which can then be acted upon by natural selection.

Transitional cell carcinoma (TCC) is a type of cancer that develops in the transitional epithelium, which is the tissue that lines the inner surface of the urinary tract. This includes the renal pelvis, ureters, bladder, and urethra. Transitional cell carcinoma is the most common type of bladder cancer and can also occur in other parts of the urinary system.

Transitional cells are specialized epithelial cells that can stretch and change shape as the organs they line expand or contract. These cells normally have a flat, squamous appearance when at rest but become more cuboidal and columnar when the organ is full. Transitional cell carcinomas typically start in the urothelium, which is the innermost lining of the urinary tract.

Transitional cell carcinoma can be classified as non-invasive (also called papillary or superficial), invasive, or both. Non-invasive TCCs are confined to the urothelium and have not grown into the underlying connective tissue. Invasive TCCs have grown through the urothelium and invaded the lamina propria (a layer of connective tissue beneath the urothelium) or the muscle wall of the bladder.

Transitional cell carcinoma can also be categorized as low-grade or high-grade, depending on how abnormal the cancer cells look under a microscope and how likely they are to grow and spread. Low-grade TCCs tend to have a better prognosis than high-grade TCCs.

Treatment for transitional cell carcinoma depends on the stage and grade of the cancer, as well as other factors such as the patient's overall health. Treatment options may include surgery, radiation therapy, chemotherapy, or immunotherapy.

Morbidity, in medical terms, refers to the state or condition of being diseased or unhealthy. It is used to describe the incidence or prevalence of a particular disease or health condition within a population, or the presence of multiple diseases or health conditions in an individual. Morbidity can also refer to the complications or symptoms associated with a disease or injury. In clinical settings, morbidity may be used to assess a patient's overall health status and their response to treatment.

DNA Mutational Analysis is a laboratory test used to identify genetic variations or changes (mutations) in the DNA sequence of a gene. This type of analysis can be used to diagnose genetic disorders, predict the risk of developing certain diseases, determine the most effective treatment for cancer, or assess the likelihood of passing on an inherited condition to offspring.

The test involves extracting DNA from a patient's sample (such as blood, saliva, or tissue), amplifying specific regions of interest using polymerase chain reaction (PCR), and then sequencing those regions to determine the precise order of nucleotide bases in the DNA molecule. The resulting sequence is then compared to reference sequences to identify any variations or mutations that may be present.

DNA Mutational Analysis can detect a wide range of genetic changes, including single-nucleotide polymorphisms (SNPs), insertions, deletions, duplications, and rearrangements. The test is often used in conjunction with other diagnostic tests and clinical evaluations to provide a comprehensive assessment of a patient's genetic profile.

It is important to note that not all mutations are pathogenic or associated with disease, and the interpretation of DNA Mutational Analysis results requires careful consideration of the patient's medical history, family history, and other relevant factors.
