IORT——术中放疗即在术中对无法切除的肿瘤、姑息手术后残留的肿瘤及根治手术后的肿瘤床给予单次剂量照射。它是一种较好的局部治疗方法,适用于远处转移率低而局部和区域复发率高的肿瘤。本院从1995.12～1996.2共进行了6例术中放疗,其中胃癌2例,直肠癌4例。术后恢复良好,5例已出院,1例将于近期出院。 IORT—Intraoperative radiotherapy involves the administration of a single dose of intraoperative radiation to unresectable tumors, residual tumors after palliative surgery, and tumor beds after radical surgery. It is a better topical treatment for tumors with low distant metastases and high local and regional recurrence rates. In this hospital, 6 cases of intraoperative radiotherapy were performed from 1995.12 to 1996.2, including 2 cases of gastric cancer and 4 cases of rectal cancer. Postoperative recovery was good. Five patients had been discharged and one patient was discharged in the near future.
