Radical prostatectomy for high grade disease: a reevaluation 1994

Area of Science:

• Urology
• Oncology
• Surgical Pathology

Background:

• High-grade prostate cancer (Gleason score 8-10) traditionally excluded patients from radical prostatectomy due to poor prognosis.
• Advancements in cancer staging and surgical techniques warrant re-evaluation of radical prostatectomy for high-grade disease.

Purpose of the Study:

• To assess the clinical outcomes of radical prostatectomy in patients with clinically localized, high-grade prostate cancer.
• To determine the impact of lymph node status on long-term outcomes after radical prostatectomy for Gleason 8-10 tumors.

Main Methods:

• Retrospective analysis of 72 men with Gleason scores 8-10 and clinically localized prostate cancer.
• Evaluation of clinical outcomes, including serum prostate-specific antigen (PSA) levels and development of distant metastases.
• Surgical assessment included pelvic lymph node evaluation via frozen section and final pathology.

Main Results:

• Of 63 men who underwent radical prostatectomy, 32% had positive lymph nodes.
• The 5-year actuarial likelihood of undetectable PSA was 43% for men with negative lymph nodes and 45% for specimen-confined disease.
• Distant metastases developed in 9% of patients, all of whom had positive lymph nodes at surgery.

Conclusions:

• Pelvic lymph node evaluation is essential for men with high-grade prostate cancer undergoing radical prostatectomy.
• Radical prostatectomy may offer a chance for surgical cure in carefully selected patients with high-grade disease and negative lymph nodes.
