术中放疗在直肠癌治疗中的应用

Intraoperative radiotherapy for rectal cancer

放疗与手术、化疗是治疗肿瘤的主要手段，术中放疗在直肠癌中的应用仍处于起步阶段。直肠癌患者接受术中放疗有术前或者术后放疗无法超越的优势，术中放疗可提高局部进展期直肠癌的局部控制率，可提高局部复发性直肠癌的总体生存率。总体而言，术中放疗是安全可行的，在直肠癌中的应用前景光明。

Radiotherapy, surgery and chemotherapy are the main treatments for cancer. Though intraoperative radiotherapy （IORT） for rectal cancer is still at its preliminary stage in China, patients carl get moro benefits from IORT than pre- or post-operative radiotherapy. IORT improves local control for locally advanced rectal cancer and improves overall survival rate of locally recurrent rectal cancer. In general, IORT is safe and feasible. It will be widely used for patients with rectal cancer in the future.
