The diagnosis of lung cancer is based on chest radiograph and computed tomography (CT) scans, and is confirmed by biopsy. Biopsy is usually performed via bronchoscopy or CT-guided biopsy. Treatment and prognosis depend upon the histological type of cancer, the stage, and the patient's performance status. Treatments include surgery, chemotherapy ...
In 1987, the UICC and AJCC staging systems were unified into the single TNM staging system. TNM is a notation system that describes the stage of a cancer, which originates from a solid tumor, using alphanumeric codes: T describes the size of the original (primary) tumor and whether it has invaded nearby tissue, N describes nearby (regional ...
Determining the extent to which a cancer has developed. Cancer staging is the process of determining the extent to which a cancer has grown and spread. A number from I to IV is assigned, with I being an isolated cancer and IV being a cancer that has metastasized and spread from its origin. The stage generally takes into account the size of a ...
Stage 0 is a pre-cancerous or marker condition, either ductal carcinoma in situ (DCIS) or lobular carcinoma in situ (LCIS). Stages 1–3 are within the breast or regional lymph nodes. Stage 4 is a metastatic cancer. Metastatic breast cancer has a less favorable prognosis. Receptor status.
Possibly, the overall Joint Committee stage is a shorter format of the TNM stage, and is usually quoted as a number I, II, III, IV derived from the TNM value grouped by prognosis; a higher number indicates a more advanced cancer and likely a worse outcome. Following is the eighth edition from 2017: Tumor (T) The T stages of bowel cancer
Euthyroid sick syndrome. Euthyroid sick syndrome ( ESS) is a state of adaptation or dysregulation of thyrotropic feedback control [1] wherein the levels of T3 and/or T4 are abnormal, but the thyroid gland does not appear to be dysfunctional. This condition may result from allostatic responses of hypothalamus-pituitary-thyroid feedback control ...
Ann Arbor staging is the staging system for lymphomas, both in Hodgkin's lymphoma (formerly designated Hodgkin's disease) and non-Hodgkin lymphoma (abbreviated NHL). It was initially developed for Hodgkin's, but has some use in NHL. It has roughly the same function as TNM staging in solid tumors. The stage depends on both the place where the ...
Tumor marker. A tumor marker is a biomarker that can be used to indicate the presence of cancer or the behavior of cancers (measure progression or response to therapy). They can be found in bodily fluids or tissue. Markers can help with assessing prognosis, surveilling patients after surgical removal of tumors, and even predicting drug-response ...
