间歇性与持续性雄激素阻断治疗晚期前列腺癌疗效比较

目的：比较间歇性与持续性雄激素阻断治疗晚期前列腺癌的疗效以及治疗产生的副作用。方法选取我科2012年1月-2013年1月收治的晚期前列腺癌患者76例，分为观察组（38例）及对照组（38例）。观察组38例行间歇性雄激素阻断治疗即药物去势加抗雄激素药物，对照组38例行持续性雄激素阻断治疗即手术去势加抗雄激素药物。比较两组患者的副反应发生率及治疗后的生活质量。结果观察组38例患者发生潮热症状者13例（34.21％）、乳房胀痛者12例（31.58％）。对照组23例患者发生潮热症状者26例（68.42％）、乳房胀痛者25例（65.79％）。比较两组潮热症状及乳房胀痛的发生率差异均有统计学意义（P＜0.05）。两组患者治疗后，观察组患者在肠道症状、性功能、尿路症状、骨痛、治疗相关症状方面都较对照组有明显的改善，生活质量大大提高，两组对比差异有统计学意义（P＜0.01）。结论间歇性联合雄激素阻断治疗可以明显降低患者治疗的副作用并且增加治疗后的生活质量，是晚期前列腺癌患者行雄激素阻断治疗的首选方案。

Efficacy comparison of intermittent and continuous androgen deprivation therapies for advanced prostate cancer

Objective To compare the efficacy and side effects of intermittent and continuous androgen deprivation therapies in the treatment of advanced prostate cancer. Methods Seventy-six patients with advanced prostate cancer treated in our department from January 2012 to January 2013 were selected and divided into the observation group （38 patients） and the control group （38 patients）. The observation group received intermittent androgen deprivation therapy, namely medical castration plus anti-androgen drugs; The control group received continuous androgen deprivation therapy, namely surgical castration plus anti-androgen drugs. The incidences of side effects and the post-treatment quality of life of the two groups were compared. Results In the observation group, 13 patients （34.21%） had hot flash symptom and 12 patients （31.58%） had breast distending pain. In the control group, 23 patients （68.42%） had hot flash symptom and 25 patients （65.79%） had breast distending pain. The two groups were significantly different in the hot flash symptom and the breast distending pain （P〈0.05）. After treatment, the observation group improved more significantly than the control group in the intestinal symptoms, sexual function, urinary symptoms, bone pain and treatment-related symptoms and the quality of life improved largely, with statistically significant differences between two groups （P〈0.01）. Conclusion Intermittent androgen deprivation therapy can significantly reduce the patients’ side effects and increase post-treatment quality of life, which is the first choice of patients with advanced prostate cancer receiving androgen deprivation therapy.
