We retrospectively investigated the tolerability and adverse events of ACT for rectal cancer in patients with diverting ileostomy. Patients and Methods: Thirty-three patients who received ACT after curative resection with ileostomy construction for rectal cancer were analyzed. We assessed completion rate, the mean relative dose intensities, and the factors affecting the tolerability of ACT. Results: The completion rate of each chemotherapy regimen was 10 out of 16 patients in oral uracil-tegafur plus leucovorin (UFT/LV), 1 out of 3 patients in oral capecitabine (Capecitabine) and 2 out of 14 patients in capecitabine plus oxaliplatin (CAPOX). The mean relative dose intensities were 77% in UFT/LV, 48% in Capecitabine, and 57% of capecitabine and 42% of oxaliplatin in CAPOX. In multivariate analysis, laparoscopic surgery (Odds ratio=11.6, p=0.021) and receiving preoperative chemoradiotherapy (Odds ratio=32.4, p=0.021) were associated with treatment completion. Conclusion: Completion rate of ACT in patients with diverting ileostomy was lower than that of colorectal cancer patients in the previous studies. UFT/LV may be a more tolerable regimen than Capecitabine or CAPOX in colorectal cancer patients with diverting ileostomy. ER -
