Neuro Endocrine Features In Small Cell Lung Cancer
What is life expectancy of small cell neuroendrocrine carcinoma that metastizied to the brain (35 tumors) and spinal fluid (3 tumors)?
Metastatic brain ca: Poor prognosis. 6-8 months or less especially if more than one. ...Read more
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Tuberous sclerosis have a large percentage of which of the following tumors? 1-renal cell carcenoma 2-adenoma 3-angiomyolipoma 3-oncocytoma 4-sarcoma
Yes: Small cell carcinomas may arise in many organs. They typically show evidence of differentiation toward certain glandular structures, called 'neuroendocrine' differentiation. Small cell cancers tend to be rapidly proliferating tumors, and thus may be treated initially with chemotherapy. ...Read moreSee 2 more doctor answers
In fine needle biopsy cancer cells r seen in group & single.benign ductal cells also seen.conclusion is carcinoma of breast.but y benign cells r seen?
Would small cell lung cancer in a mediastinal lymph node be classed as cancer of unknown primary if lung was clear on imaging.
SCLC arises next: to the bronchi and may not be visible on CT imaging in spite of the fact that it has already spread to a lymph node. Very rarely this same type of tumor arises in the prostate, cervix or gastrointestinal tract. Perhaps a sophisticated imaging technique such as PET scanning could detect the primary tumor in the lung, though knowing the type of tumor already can guide their treatment effectively. ...Read more
Mesothelioma biopsy says 'portions of fibrous tissue infiltrated by malignant cells forming nests. tumor cells +'ve for CK7 and calretinin. prognosis?
Marker not prognosis: CK7 and calretinin are used to verify that the tumor is mesothelial in origin (versus adenocarcinoma of the lung). It does not provide information about prognosis. Factors associated with pleural mesothelioma prognosis include: functional status, blood counts, histology (epithelial best vs fibrosarcomatous poorest), and tumor size (degree of involvement of pleural cavity). Several new trials. ...Read more
3mm hypodense liver lesion in caudate lobe & two 3mm hypodense pancreatic head lesions on CT in setting of carcinoid workup. Can these be tumors?
May or may not be: It takes time and follow up CT scans to see if these tumors are growing in size. if they are not tumors(cancer) it will remain unchanged in size over a period of 3-6 months. A biopsy may be required to confirm it in case these lesions are increasing in size(growing bigger). They are too small to do a biopsy now, need to be at least 1Cm or bigger. ...Read more
Colon biopsy:huge tubulovillous adenoma with marked atypia, multi foci adenocarcinoma in situ &one tiny focus suggestive of micro invasion.Is it cancer?
Not directly: Ecog ps (performance status) refers to the functional status of patients with cancer (any type, not just small cell). Ps 2 describes pts that " are ambulatory and capable of all selfcare but unable to carry out any work activities. Up and about more than 50% of waking hours" ps scores are used to decide how intense of treatment cancer patients should undergo. ...Read moreSee 1 more doctor answer
Occasionally: Secondary cancer. Wilms tumor survivors have a small risk of developing another type of cancer within 15 years after wilms tumor was first diagnosed. The most important risk factors are whether treatment included radiation therapy and doxorubicin. Wilms tumor in children can also spread or metastasis thru the bloodstream to the brain, lungs or lymph nodes occasionally in children. ...Read moreSee 1 more doctor answer
Different cell types: lsmall cell cancer of the ung is a neuroendocrine tumor responding to chemo such as the adriamycins (doxorubicin). Non small cell cancer represents the adenocarcinomas and squamous cell cancers requiring a different groujp of drugs that usually include the platinums and the newer monoclonal antibodies. ...Read more

Lung nodules in 3 lobes of smoker. 9mm does not enhance ; no calcificat. Does this suggest small cell or large cell cancer? Needle biopsy scheduled.
Limited: Most with this diagnosis have less than 2 years of survival, unless found when small and peripheral so it can be removed! ...Read more
With regard that carcinoid tumor produce excessive amount of serotonin, does enlarged pituitary gland go hand in hand with carcinoid tumor?
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
