Negative repeat transurethral resection of prostate fails to identify patients with stage A1 prostatic carcinoma at lower risk of progression: a long-term study.
Stage A1 (low-grade and low-volume) adenocarcinoma is associated with a low likelihood of progression. Repeat transurethral resection has been used to identify patients at increased risk (residual cancer noted) as well as those at low risk of progression (no residual cancer noted). We recently evaluated the ability of this technique to define a low-risk patient population. We reviewed the records of 24 patients who underwent repeat transurethral resection after they were identified as having Stage A1 prostatic cancer on initial resection (Gleason score < 5, tumor volume comprising < 5% of the resection specimen). Despite no evidence of residual carcinoma on repeat resection, 3 patients (13%) progressed at a mean follow-up of seven years (2 locally, 1 locally and distantly). We conclude that repeat resection does not effectively evaluate the risk of progression and that other techniques including transrectal ultrasonography and serial prostate-specific antigen measurements should be similarly evaluated.
