Nonprostatic adenocarcinoma involving the prostate

Definition Metastatic adenocarcinomas to the prostate are secondary adenocarcinomas that have spread to the prostate gland via angiolymphatic invasion. More commonly, adenocarcinomas from contiguous organs (e.g., bladder and colorectum) directly invade the prostate. Clinical features Epidemiology Distant metastases to the…

Genetics and genomics in prostate cancer

Prostate cancer genetics Prostate carcinoma is a multifactorial disease influenced by both environmental and genetic factors. Positive family history is the strongest epidemiological risk factor after advancing age and ethnic background. Prostate carcinoma can be divided into three groups: hereditary,…

Prostate cancer staging in radical prostatectomy

Definition The objective of staging is to group malignancies with a similar prognosis and therapeutic approach to be able to compare clinicopathologic data on a homogeneous patient population. Staging involves determining the anatomic extent or spread of prostate cancer at…

Cryoablation therapy-induced changes

Definition Cryosurgical ablation refers to rapid deep freezing of the prostate gland. Multiple cryoprobe needles filled with circulating liquid nitrogen transform the prostate into an ice ball. Cryoablation results in substantial tissue destruction and death of benign and malignant cells.…

Hormonal ablation-induced changes

Definition Androgen deprivation therapy is a popular form of treatment for prostate cancer. Androgen deprivation can be achieved with multiple methods: Orchiectomy Estrogen Gonadotropin-releasing hormone antagonists (luteinizing hormone–releasing hormone [LH-RH] agonists) Anti-androgen 5α-reductase inhibitors Agents are used for preoperative tumor…

Radiation-induced changes

Definition The primary effect of radiation therapy is the damage of endothelial cells, which causes ischemia that leads to atrophy. Radiation-induced changes on prostatic tissue are variable, more severe, and durable when delivered as interstitial seed implants (brachytherapy) than by…
