Prognostic and predictive biomarkers in metastatic castration-resistant prostate cancer.
نویسنده
چکیده
AJA Biomarkers are any manifestation of a biological process, particularly in patients, that can be measured quantitatively. They can reflect either normal (physiologic) or disease (pathophysiologic) processes. Biomarkers are used in various contexts in prostate cancer. Prognostic biomarkers are related to the natural history of a disease over time, whereas predictive biomarkers are linked to the benefit of specific therapies. Surrogate biomarkers are intermediate outcomes that are associated with gold standard outcomes, such as improved survival. Surrogate biomarkers can relay information on whether a treatment is benefitting a patient. Other biomarkers commonly applied in oncology are pharmacokinetic biomarkers, which measure the effect of the host (patient) on drug metabolism and disposition, and pharmacodynamic biomarkers, which measure the effect of a treatment on a tumor or patient. The biomarkers that are most relevant to this discussion are prognostic and predictive biomarkers because they help us identify patients in need of therapy, and they also help us select patients for the specific treatments that are most likely to be beneficial.

Advances in our understanding of the mechanisms driving castration-resistant prostate cancer have promoted the development of several new drugs including androgen receptor-directed therapy and chemotherapy. Concomitant docetaxel treatment at the beginning of hormonal therapy for metastatic prostate cancer has resulted in longer overall survival than with hormonal therapy alone. Elucidating an a...

The Iranian Society of Nuclear Medicine practical guideline on radioligand therapy in metastatic castration-resistant prostate cancer using 177Lu-PSMA
Prostate-specific membrane antigen (PSMA) is a type II transmembrane protein, which is anchored in the cell membrane of prostate epithelial cells. It is highly expressed on prostate epithelial cells and strongly up-regulated in prostate cancer. Although, 177Lu-PSMA has been recently introduced for radionuclide therapy of metastatic castration-resistant prostate cancer (mCRPC) with co...

BACKGROUND Men with prostate cancer will not die of the disease until it progresses to the metastatic castration resistant stage. At that stage, the median survival is 9 to 30 months. METHODS Recently approved and emerging treatments for metastatic castration-resistant prostate cancer (mCRPC) were reviewed based on their mechanisms of action, as well as sequencing and combining these treatmen...

PURPOSE Circulating tumor cells (CTC) have been recently accepted by the Food and Drug Administration of the United States as a prognostic tool in advanced prostate cancer. However, a number of questions remain about the use of the test. The optimal clinical cut-off has never been determined. Also, the predictive value of CTCs in the setting of low-burden advanced prostate cancer has not been e...
