Evaluation of prostatic cancer prevalence in patients with prostatic-specific antigen between 4 and 10 and normal digital rectal examination.

Background: Prostate cancer is one of the most common male cancers. The prevalence of prostate cancer is different due to genetic and environmental factors. Diagnosis of prostate cancer is by biopsy due to prostate-specific antigen (PSA) and Digital Rectal Examination (DRE).

Prostate cancer: Relationship between vascular diameter, shape and density and Gleason score in needle biopsy specimens.

Background: Tumor growth requires expansion and development of vascular network. An increase in Gleason score is representative of an increase in tumor invasion and extent. In this study, the relationship between Gleason score and vascular characteristics of needle biopsy samples in prostate cancer patients has been evaluated.
