Background and objectives: A 1 cm Distal Resection Margin (DRM) was recommended. Controversy still exists if we can obtain DRM less than 1 cm who had preoperative Chemoradiotherarpy (CRT). Our study aimed to determine the clinical outcomes who had subcentimeter DRM. Methods: 740 patients with rectal cancer were assessed. 145 patients with rectal cancer underwent curative resection after preoperative CRT were included. The median follow-up time was 28 months. Results: 36 (24.8%) patients had DRM <1 cm. Local recurrence occurred in 27 patients (18.6%). Overall recurrence was significantly higher in patients with DRM ≤ 0.4 cm than DRM >0.4 cm (50% vs. 16.1%; p=0.015). Moreover, patients who had DRM ≤ 0.4 cm were significantly associated with higher local recurrence than systemic recurrenc.. Read More»
