Association of current molecular subtypes in urothelial carcinoma with patterns of muscularis propria invasion.

Urothelial carcinoma is subdivided into luminal (L), basal (B), and p53-wild-type (WT) molecular subtypes, with basal and p53-WT groups showing more aggressive course and poor treatment response, respectively. The literature on molecular subtypes of UC includes a mixture of different stages. We investigated the molecular profile and outcome of pure cohort of muscle invasive bladder carcinoma (MIBC) considering two distinct patterns of muscularis propria (MP) invasion.

Atypical Small Acinar Proliferation: Repeat Biopsy and Detection of High Grade Prostate Cancer.

Purpose. Atypical small acinar proliferation (ASAP) is diagnosed in 1-2% of prostate biopsies. 30-40% of patients with ASAP may be diagnosed with prostate cancer (PCa) on repeat biopsy.

Can effect of finasteride on prostate-specific antigen be used to decrease repeat prostate biopsy?

Objectives: Patients often undergo multiple prostate biopsies for persistently elevated prostate-specific antigen (PSA) levels. Finasteride decreases serum PSA by approximately 50%. We performed a pilot study to examine the correlation among finasteride, PSA, and PSA density (PSAD) to identify patients who could be excluded from repeat prostate biopsy.
