ASTRO 2016:极大分割放疗和常规放疗治疗前列腺癌,毒性相当

ASTRO年会上的一项随机、开放标签、3期试验的早期毒性分析数据显示:对于中危前列腺癌患者,极大分割放疗与常规放疗相比,2年后的不良事件发生情况相似。

来自瑞典Umeå大学的Anders Widmark博士和同事们对1200例中度风险前列腺癌患者进行了研究,关于极大分割放疗和常规放疗的非劣效性试验。

患者被随机分到常规分次放疗(中位数78 Gy),超过8周的时间,7次疗程;或者极大分割放疗(中位数42.7 Gy),在超过2.5周时间里,每个一个工作日,共计39次疗程。

所有患者不能接受雄激素剥夺治疗。

为期2年的中期分析数据来自866例患者,总患者人群的平均随访时间为4.2年。

极大分割放疗与常规放疗相比,第2年,2级或更严重的泌尿系统毒性(5.4% vs. 4.6%)或肠道毒性(2.2% vs. 3.7%)没有组间差异。对于放疗结束后的急性泌尿系统毒性也没有组间差异(27.6% vs. 22.8%),但是极大分割放疗组患者的放疗结束后急性肠道毒性发生率更高(9.4% vs. 5.3%; P = .023)。

2年后,两组患者的阳痿率为34%,与基线相比,增加了16%。

病人报告结果显示,极大分割放疗组患者1年后,四项排尿功能更糟糕(P = .001),这些患者在放疗后的10项肠道功能也更差(P < .001);但是这种差异的持续时间没有超过3个月和6个月。

第2年,患者报告的排尿和肠功能没有显着不同;任何时间节点上的性功能也没有差异。

研究表明,对于中危前列腺癌患者,极大分割放疗与常规放疗相比,具有等同的晚期毒性。
