2012-08-03 朱金 医学论坛网

  《临床肿瘤学》(Clinical Oncology)杂志近期发表的一项研究可能证明了调强放疗同步化疗用于治疗肛门癌有效且患者对其耐受性良好。   该研究纳入了78例在13个社区癌症中心接受调强放疗(IMRT)治疗的肛门癌患者。65例(83%)为T1~T2期,64%为N0期,9%为M1期;5例患者为HIV阳性。除1例患者外,所有患者均同步接受化疗。包括腹股沟淋巴结在内的骨盆的中位照射

  《临床肿瘤学》(Clinical Oncology)杂志近期发表的一项研究可能证明了调强放疗同步化疗用于治疗肛门癌有效且患者对其耐受性良好。

  该研究纳入了78例在13个社区癌症中心接受调强放疗(IMRT)治疗的肛门癌患者。65例(83%)为T1~T2期,64%为N0期,9%为M1期;5例患者为HIV阳性。除1例患者外,所有患者均同步接受化疗。包括腹股沟淋巴结在内的骨盆的中位照射剂量是45 Gy。原发部位和受累淋巴结的中位照射剂量被提高至55.8 Gy。

  结果显示,研究对整个队列中位随访16个月(范围:0~72 个月)。≥3级急性毒性反应包括胃肠道的27.7%和皮肤的29.0%。12.9%的患者发生了4级急性血液学毒性。64例(88.9%)患者完全缓解。2年无结肠造口术生存、总生存、无局部复发和无远处复发的概率分别是 81.2%、86.9%、83.6%和81.8%。

JAMA:调强放疗(IMRT)治疗前列腺癌的地位被认可

       据《美国医学会杂志》4月17日发表的对3种非转移性前列腺癌放疗方法的比较研究结果,虽然调强放疗(IMRT)比适形放疗(CRT)可导致较多患者出现勃起功能障碍,但仍支持IMRT广泛用于前列腺癌治疗。与IMRT相比,费用最高的最新质子治疗方法会产生较多的胃肠道副作用,且未见疗效优势(JAMA 2012;307:1611-1620)。
