For example, tumor markers like Ki-67 can be used to choose form of treatment or in prognostics but are not useful to give a diagnosis, while other tumor markers have the opposite functionality. Therefore it's important to follow the guidelines of the specific tumor marker. Tumor markers are mainly used in clinical medicine to support a ...
For example, Notch has been found to promote the expression of cyclin D3 and Cdk4/6 in human T-cells, thereby promoting the phosphorylation of Rb and facilitating the G1/S transition, implicating its role in cancer as several gain-of-function mutations in NOTCH1 have been identified in human acute T-cell lymphoblastic leukemias and lymphomas.

This test is intended for women with early-stage (Stage I or II), node-negative, estrogen receptor-positive (ER+) invasive breast cancer who will be treated with hormone therapy. Oncotype DX looks at a panel of 21 genes in cells taken during tumor biopsy. The results of the test are given in the form of a recurrence score that indicates ...
In addition to these common markers, there are prognostic markers specific to different cancer types. For example estrogen level, progesterone and HER2 are markers specific to breast cancer patients. There is evidence showing that genes behaving as tumor suppressors or carcinogens could act as prognostic markers due to altered gene expression ...
More recently, JAG1 expression changes have been implicated in many types of cancer. Specifically, up regulation of JAG1 has been correlated with both poor overall breast cancer survival rates and an enhancement of tumor proliferation in adrenocortical carcinoma patients. [13] [27] [28] [29]
CA 27.29 (aka BR 27.29) and CA 15-3 measure different epitopes of the same protein antigen product of the MUC1 gene seen in breast cancer. CA 27.29 has enhanced sensitivity and specificity compared to CA 15-3 and is elevated in 30% of patients with low-stage disease and 60 to 70% of patients with advanced-stage breast cancer.
