Abstract

Our previous study reported the favorable short‑term outcome and good tolerance of integrating oxaliplatin into capecitabine‑based (XELOX regimen) preoperative chemoradiotherapy (CRT) for locally advanced rectal cancer (LARC). The present study reported the long‑term oncological outcome of this phase II study. A total of 47 patients with rectal adenocarcinoma (stage II or III) were enrolled and received radiotherapy (46 Gy in 23 fractions) in combination with capecitabine (1,000 mg/m2, twice daily, on days 1‑14 and 22‑35) and oxaliplatin (130 mg/m2 on days 1 and 22). Overall survival (OS) rate, disease‑free survival (DFS) rate and cumulative incidence of recurrences and long‑term complications were calculated or observed. As a result, 41 patients underwent surgery after preoperative CRT, and the cumulative OS rates at 1, 3 and 5 years for these patients were 100.0, 84.5 and 81.8%, respectively. For the 38 patients who received R0 resection, the cumulative OS rates at 1, 3 and 5 years were 100.0, 89.0 and 86.2%, respectively, while the cumulative DFS rates at 1, 3 and 5 years were 94.6, 75.3 and 69.7%, respectively. After follow‑up at 84 months, the cumulative incidence rates of local and distant recurrences at 5 years were 6.6 and 28.2%, respectively. Oxaliplatin‑associated long‑term complications were seldom observed. Overall, the addition of oxaliplatin to capecitabine‑based preoperative radiotherapy achieved favorable OS and DFS without increased long‑term complications in patients with LARC. Therefore, this preoperative CRT strategy is a feasible option for such patients.
