A decision analysis that modeled three treatment strategies was used to model the impact of initial therapy on outcomes for men with localized prostatic carcinoma who were 60- 75 years of age. The results concerning radical prostatectomy external-beam radiation therapy and watchful waiting are discussed. The relationship between vasectomy and prostate cancer was examined. Study results suggest that a vasectomy increases one's chances of acquiring prostate cancer. The relationship between vasectomy and prostate cancer was examined.
Results suggest that a vasectomy does increase one's risk of acquiring prostate cancer.
Various treatment modalities involving monotherapy alone have been associated with dismal results. Radical treatment for prostate cancer aims at complete eradication of tumor. This review of published data makes clear that the goal is less frequently achieved than commonly presumed. Local regrowth is associated with a poorer prognosis. A substantial proportion of patients whose prostate glands are rebiopsied more than 18 months after radiation therapy also have residual tumor.
