Ten-year follow-up of neoadjuvant therapy with goserelin acetate and flutamide before radical prostatectomy for clinical T3 and T4 prostate cancer: update on Southwest Oncology Group Study 9109.

Objective: To update the results with 10-year data of a phase II prospective trial of neoadjuvant hormonal therapy with goserelin acetate and flutamide followed by radical prostatectomy for locally advanced prostate cancer (SWOG 9109). The optimal management for clinical stage T3 and T4 N0,M0 prostate cancer is uncertain.

Materials And Methods: Sixty-two patients with clinical stage T3 and T4 N0,M0 prostate cancer were enrolled.

Health-related quality of life results in pathologic stage C prostate cancer from a Southwest Oncology Group trial comparing radical prostatectomy alone with radical prostatectomy plus radiation therapy.

Purpose: To compare short- and long-term effects of adjuvant treatment versus observation after surgery on health-related quality of life (HRQL) of prostate cancer patients.

Patients And Methods: The Southwest Oncology Group (SWOG) intergroup trial compared radical prostatectomy (RP) plus observation versus RP plus adjuvant radiation therapy (RT). Two-hundred seventeen of 425 therapeutic trial patients were eligible and registered to the HRQL study.

Erectile function outcome reporting after clinically localized prostate cancer treatment.

Purpose: In conjunction with the assignment to update the Guidelines for Management of Clinically Localized Prostate Cancer, the American Urological Association Prostate Cancer Guideline Update Panel performed a side analysis of the reporting of erectile function outcomes in this clinical context as published in the medical literature.

Materials And Methods: Four National Library of Medicine PubMed(R) Services literature searches targeting articles published from 1991 through early 2004 were done to derive outcome reporting (efficacy or side effects) for the treatment of clinical stage T1 or T2 N0M0 prostate cancer. A database was constructed containing descriptions relating to erectile function as well as numerical frequency rates of complete erectile dysfunction, and partial and intact erectile function for various treatments.

Variation in the definition of biochemical recurrence in patients treated for localized prostate cancer: the American Urological Association Prostate Guidelines for Localized Prostate Cancer Update Panel report and recommendations for a standard in the reporting of surgical outcomes.

Purpose: The American Urological Association Prostate Guideline Update Panel was charged with updating the Guidelines for Clinically Localized Prostate Cancer. In assessing outcomes with treatment, it became apparent that a highly variable number of definitions exist with respect to biochemical recurrence. Herein, we review the variability in published definitions of biochemical recurrence and make recommendations directed toward improving this terminology by recommending a standard definition in patients treated with radical prostatectomy.

Chemoprevention of prostate cancer.

Prostate cancer is a common malignancy with multiple potential opportunities for cancer prevention. As the genetic basis of this malignancy is further understood, prevention strategies will be developed for individual patients based on specific risk factors and pathways of carcinogenesis. The PCPT has conclusively proven that prostate cancer prevention is possible.

Chemoprevention of prostate cancer with finasteride.

Prostate cancer is a significant cause of disease and death, making it an attractive target for chemoprevention. The association between lifetime exposure to dihydrotestosterone and risk of developing prostate cancer suggests that chemoprevention is possible with 5alpha-reductase inhibition. The recently completed Prostate Cancer Prevention Trial indicates that chemoprevention is possible with the 5alpha-reductase inhibitor finasteride.

Prostate cancer detection strategies.

Prostate cancer is the most common malignancy in men and, as a result, there has been a nationwide emphasis on screening and detection. With the widespread use of the prostate-specific antigen (PSA), prostate cancer screening effectively detects localized prostate cancer. However, recent reports have identified a significant proportion of prostate cancer in men with low PSA levels.

Mechanisms of disease: Prostate cancer--a model for cancer chemoprevention in clinical practice.

Prostate cancer is a significant cause of cancer death, making it an attractive target for chemoprevention. Epidemiologic studies and the Prostate Cancer Prevention Trial indicate that chemoprevention is possible. Strategies for prevention include hormonal manipulation and limiting accumulation of genetic damage with anti-inflammatory agents and/or dietary antioxidants.

Prognostic features in men who died of prostate cancer.

Purpose: Since the advent of widespread prostate specific antigen (PSA) based screening in the United States, the risk of over diagnosis as well as delayed diagnosis due to existing PSA thresholds has become a concern. Treatment decision planning is generally linked to prognostic variables, most notably PSA, clinical stage and Gleason grade. We examined these and other prognostic variables in a cohort of men who ultimately died of prostate cancer.

Local and systemic therapy for patients with metastatic prostate cancer: should the primary tumor be treated?

Data from well-designed, prospective clinical trials are lacking to support treatment of primary tumor in men diagnosed with metastatic prostate cancer. However, a growing body of evidence suggests that treatment of the primary tumor may enhance cancer control and survival in some men. This evidence is examined and recommendations are made for identifying patients with metastatic prostate cancer who may benefit from definitive treatment of the prostate tumor.
