ABSTRACT
<p><b>OBJECTIVE</b>To observe the local control rate, survival time and side effect of three-dimensional conformal radiation therapy combined with Tegafur for postoperative recurrent rectal carcinoma.</p><p><b>METHODS</b>Forty patients with postoperative recurrent rectal carcinoma received three-dimensional conformal radiation therapy, 1.8 - 2.0 Gy/once, 5 times every week and the total dose was 54 - 65 Gy. At the same time, the patients took Tegafur orally 40 mg/m(2) twice per day for consecutive 28 days, and one cycle lasted for 42 days. The chemotherapy was applied for 2 cycles after radiotherapy.</p><p><b>RESULTS</b>The total effective rate (CR + PR) was 70.0%, improvement rate was 90.0%, 1-year survival rate was 70.0%, and 1-year local control rate was 62.5%. There was only a little side effect.</p><p><b>CONCLUSIONS</b>Three-dimensional conformal radiation therapy combined with Tegafur for postoperative recurrent rectal carcinoma have definite effect, with a high local control rate, and patients well tolerance the treatment without serious side effect. It can apparently improve the life quality of the patients.</p>
