Small-cell lung carcinoma (SCLC) has long been divided into two clinicopathological stages, termed limited stage (LS) and extensive stage (ES). [8] The stage is generally determined by the presence or absence of metastases, whether or not the tumor appears limited to the thorax, and whether or not the entire tumor burden within the chest can feasibly be encompassed within a single radiotherapy ...
Unlike extensive-stage small cell lung cancer, limited-stage small cell lung cancer is potentially curable. [4] In limited small cell lung cancer, the median overall survival time is approximately 12–16 months, with five year survival rate of approximately 26% and long-term survival rate of approximately 4–5%. [19]
Around 15% of cases are small-cell lung cancer (SCLC), and the remaining 85% (the non-small-cell lung cancers or NSCLC) are adenocarcinomas, squamous-cell carcinomas, and large-cell carcinomas. After diagnosis, further imaging and biopsies are done to determine the cancer's stage based on how far it has spread.
Combined small cell lung carcinoma (or c-SCLC) is a form of multiphasic lung cancer that is diagnosed by a pathologist when a malignant tumor, arising from transformed cells originating in lung tissue, contains a component of small cell lung carcinoma (SCLC) mixed with one or more components of any histological variant of non-small cell lung carcinoma (NSCLC) in any relative proportion.
Diagnosis: To find out whether an abnormality seen on a chest x-ray or CT scan is indeed lung cancer, and what histological type it is (small cell or non-small cell). Staging: To find out whether a structure, such as a lymph node in the mediastinum, has already been invaded by cancer or not.
Large-cell lung carcinoma (LCLC) is a heterogeneous group of undifferentiated malignant neoplasms originating from transformed epithelial cells in the lung. LCLCs have typically comprised around 10% of all NSCLC in the past, although newer diagnostic techniques seem to be reducing the incidence of diagnosis of "classic" LCLC in favor of more ...
