To evaluate the efficacy and toxicity of pre-operative radiotherapy (RT) combined with oral tegafur-uracil (UFUR) plus leucovorin (LV) in rectal cancer.
Sixty-five patients with rectal adenocarcinoma (clinical staged T2-4N0-2M0) received pelvic RT of 45 Gy in 20 fractions over 28 days. Concurrent chemotherapy consisted of UFUR (200 mg/m(2)/day) and LV (45 mg/day) on day 1-28. UFUR (250 mg/m(2)/day) and LV were continued on day 36-63. Surgery was performed on day 70.
Sixty-three patients completed the concurrent chemoradiotherapy (CCRT) and 56 received curative or palliative surgery. Among the 52 patients receiving curative resection, downstaging (DS) occurred in 39 (75%), pathological complete response in 13 (25%), and sphincter preservation was achieved in 16 of 29 (55%) with lower-seated tumors. With a median follow-up time of 33 months, local failure developed in 4 (8%) and distant metastases occurred in 7 (14%). The 3-year overall survival was 92% and disease-free survival 76%. For all 65 patients, grade 3-4 diarrhea developed in 6 (9%) and grade 3-4 leucopenia observed in 2 (3%).
Oral UFUR + LV administered with pre-operative RT are effective in tumor DS, pathological complete response, and sphincter preservation with tolerable toxicity in rectal cancer.
评估术前放疗(RT)联合口服替加氟尿嘧啶(UFUR)加亚叶酸钙(LV)治疗直肠癌的疗效和毒性。
65例直肠腺癌患者(临床分期为T2 - 4N0 - 2M0)接受盆腔放疗,28天内分20次给予45 Gy。同步化疗方案为第1 - 28天给予UFUR(200 mg/m²/天)和LV(45 mg/天)。第36 - 63天继续给予UFUR(250 mg/m²/天)和LV。第70天进行手术。
63例患者完成同步放化疗(CCRT),56例接受了根治性或姑息性手术。在52例接受根治性切除的患者中,39例(75%)出现降期(DS),13例(25%)达到病理完全缓解,29例低位肿瘤患者中有16例(55%)实现了括约肌保留。中位随访时间为33个月,4例(8%)出现局部复发,7例(14%)发生远处转移。3年总生存率为92%,无病生存率为76%。在所有65例患者中,6例(9%)出现3 - 4级腹泻,2例(3%)出现3 - 4级白细胞减少。
术前放疗联合口服UFUR + LV对直肠癌的肿瘤降期、病理完全缓解和括约肌保留有效,且毒性可耐受。
