课件 | 前列腺癌大分割放射治疗
前列腺癌的α/β值为1~3Gy，低于邻近的正常组织，其中直肠和膀胱的α/β值约为3~5Gy）。从放射生物学角度，前列腺癌更适于大分割方案放疗。在接受同样分割剂量放疗时，前列腺癌具有更大的治疗获益比。
本文分享学习由中国人民解放军总医院放疗科曲宝林教授整理总结的前列腺癌大分割放射治疗。仅供各位老师学习参考。感谢曲宝林教授授课！（请注意本课件发布时间较早，其中信息可能已经发展或者有所改变）。

现有研究结果提示，中等剂量大分割及超大分割已成为局限性前列腺癌根治性治疗的标准治疗选择，大分割主体病灶同步局部加量是重要进展，术后放疗领域的研究已证实中等分割方案与常规分割具有相当的疗效和安全性，寡转移灶大分割放疗能有效控制病灶进展，还可显著延缓系统性治疗需求，而盆腔淋巴结预防性照射的大分割方案则仍需更多循证证据支持。

大分割放疗代表了前列腺癌放射治疗的重要发展方向，未来基于更多高级别证据的发表，大分割放疗有望为不同临床特征的前列腺癌提供更加精准和个性化的治疗选择，为更多患者带来获益。
