Prospective clinical study of capecitabine plus oxaliplatin concurrent chemoradiotherapy after radical resection of rectal cancer

摘要

To investigate the efficacy and safety of concurrent chemoradiotherapy with capecitabine or oxaliplatin in locally advanced (T3-4/N?+?M0) rectal cancer. 56 patients with rectal cancer after radical operation were randomly divided into CAPE-OX-CRT group: capecitabine?+?oxaliplatin concurrent chemoradiotherapy (30 cases), CAPE-CRT group: capecitabine concurrent chemoradiotherapy (control, 26 cases). The incidence of grade 1–2 acute toxicity in CAPE-OX-CRT group during concurrent CRT was significantly higher than that in control group, the difference was statistically significant (P 0.05). No grade 4 toxicity was found in both groups. The incidences of interrupted or suspend concurrent chemotherapy in both groups were 19.23% and 46.67%, respectively, P 0.05). The completion rate of adjuvant chemotherapy in control group was higher than that in CAPE-OX-CRT group, but the difference was not statistically significant (P?>?0.05). In postoperative adjuvant chemotherapy, the incidence of bone marrow suppression in CAPE-OX-CRT group was higher than that in control group (P?
