Effecting observation of 3-dimensional conformal radiotherapy combined with chemotherapy for rectal cancer of postoperative local recurrence / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effects of 3-dimensional conformal radiation therapy combined with chemotherapy for rectal cancer of postoperative local recurrence.</p><p><b>METHODS</b>Fifty-six rectal cancer patients of postoperative local recurrence were treated with 3-dimensional conformal radiotherapy (66 approximately 68 Gy in 2 Gy daily fraction) combined with chemotherapy (5-Fu 0.75, Days 1 - 5 and Days 29 - 33; Cisplatin 40 mg, Days 1 - 3 and Days 29 - 31). Acute and late radioreactions and survival rates were observed. Kaplan-Meier method was used for survival analysis.</p><p><b>RESULTS</b>The 1, 2, 3 years local control rate was 87.5%, 66.1%, 38.2%, respectively. The 1, 2, 3 years disease-free survival and overall were 82.7%, 56.6%, 30.1% and 88.3%, 66.8%, 44.2%, respectively. The median survival was 25.3 months. Acute small enteritis were the most common but acceptable radioreactions Grade 1 approximately 2. No late radioreactions occurred.</p><p><b>CONCLUSIONS</b>3-dimensional conformal radiotherapy combined with chemotherapy can be considered as an effective and feasible approach to cancer patients of postoperative local recurrence.</p>
