Prostate Cancer, Treatment and Response of the Hematological System in Mexican Population

Abstract

Androgen deprivation therapy (ADT) is the basis for the control of prostate cancer. High levels of prostate-specific antigen (PSA) and high Gleason grade correlate, define the aggressiveness of the cancer in order to establish its treatment and prognosis. This work evaluated the response of 910 patients diagnosed with prostate cancer, separated into three groups according to their response to treatment by ADT: (1) sensitive (TSPC); (2) palliative and did not accept treatment, and (3) group with recurrence or treatment resistance (TRPC). All patients with prostate cancer treated with ADT, and regardless of whether or not they had undergone surgery or taken to radiotherapy, presented with anemia. The hematological response due to the leukocyte/lymphocyte index (L/L) is increased at the end of treatment, possibly due to inflammatory processes generated by cancer, and baseline overweight and obesity. Patients with biochemical relapse exhibit a higher platelet count, suggesting that these cells could participate in the recurrence process and in metastasis (78%) in these patients. The coagulation index (INR) could be an indicator of the platelet response to be considered during the treatment and monitoring of patients.
