Gonadotropin-releasing hormone agonists (GnRHa) are associated with greater risk of coronary heart disease and myocardial infarction in men with prostate cancer, but little is known about their potential effects on cardiovascular mortality. We assessed the relationship between duration of GnRHa therapy and cardiovascular mortality in a large randomized trial of men treated with short-term versus longer-term adjuvant goserelin and radiation therapy (RT) for locally advanced prostate cancer.


From 1992 to 1995, 1554 men with locally advanced prostate cancer (T2c-4, prostate-specific antigen [PSA] <150 ng/ml) received RT and 4 mo of goserelin and then were randomized to no additional therapy (arm 1) or 24 mo adjuvant goserelin (arm 2) in a phase 3 trial (Radiation Therapy Oncology Group [RTOG] 92-02). Cox regression analyses were performed to evaluate the relationship between treatment arm and cardiovascular mortality. Covariates included age, prevalent cardiovascular disease (CVD), hypertension, diabetes (DM), race, PSA, Gleason score, and stage.


After median follow-up of 8.1 yr, 185 cardiovascular-related deaths had occurred. No increase in cardiovascular mortality occurred for men receiving a longer duration of goserelin. At 5 yr, cardiovascular mortality for men receiving longer-term adjuvant goserelin was 5.9% versus 4.8% with short-term goserelin (Gray's p=0.16). In multivariate analyses, treatment arm was not significantly associated with increased risk of cardiovascular mortality (adjusted hazard ratio [HR]=1.09; 95% confidence interval [CI], 0.81-1.47; p=0.58; when censoring at time of salvage goserelin, HR=1.02, 95%CI, 0.73-1.43; p=0.9). Traditional cardiac risk factors, including age, prevalent CVD, and DM, were significantly associated with greater cardiovascular mortality.


Longer duration of adjuvant GnRHa therapy does not appear to increase cardiovascular mortality in men with locally advanced prostate cancer.
