This autocrine loop provides essential cell survival signals to the pancreatic cancer cells. [4] Type IV collagen is expressed close to the cancer cells in vivo, forming basement membrane like structures on the cancer cell surface that colocalize with the integrin receptors. The interaction between type IV collagen produced by the cancer cell ...
The cell survival curve is a curve often used in radiobiology that represents the relationship between the amount of cells retaining reproductive capabilities and the absorbed dose of radiation from said cells.
Ki-67 is a nuclear antigen expressed in proliferating cells that is coded by the MKI67 gene on chromosome 10, and is expressed during the GI, S, G2, and M phases of the cell cycle. Cells are then stained with a Ki-67 antibody, and the number of stained nuclei is then expressed as a percentage of total tumor cells.
Small cell lung cancer has a five-year survival rate of 4% according to Cancer Centers of America's Website. [5] The American Cancer Society reports 5-year relative survival rates of over 70% for women with stage 0-III breast cancer with a 5-year relative survival rate close to 100% for women with stage 0 or stage I breast cancer.
T cells must replicate after arriving at the tumor site to effectively kill the cancer cells, survive hostile elements and migrate through the stroma to the cancer cells. This is affected by the tumor microenvironment. The draining lymph nodes are the likely location for cancer specific T cell replication, although this also occurs within the ...
Survival rate is a part of survival analysis.It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy.

An elevated mitotic index indicates more cells are dividing. In cancer cells, the mitotic index may be elevated compared to normal growth of tissues or cellular repair of the site of an injury. [2] The mitotic index is therefore an important prognostic factor predicting both overall survival and response to chemotherapy in most types of cancer ...
