Abstract Background The purpose of this study was to compare short-course radiotherapy (SC) or neoadjuvant long-course chemoradiotherapy (LC) treatment for locally advanced rectal cancer patients. Methods Patients with a diagnosis of locally advanced rectal cancer (LARC) who had undergone neoadjuvant radiotherapy before surgery between 2013 and 2018 at the medical center in China were included in this study. All patients’ MRI confirmed T2N+M0 or T3-4N0-3M0 clinical stages. Patients in the SC group received pelvic radiotherapy with a dose of 5 × 5 Gy (with or without chemotherapy at any time), followed by immediate or delayed surgery. Patients in the LC group received a dose of 50–50.4 Gy in 25–28 fractions, concomitantly with FOLFOX or capecitabine-based chemotherapy, followed by surgery 4–6 weeks later. All clinical data were retrospectively collected, and long-term follow-up was completed and recorded at the same time. Results A total of 170 were eligible to participate in this study, 32 patients in the SC group, and 138 in the LC group. The median follow-up time of living patients was 39 months. The disease-free survival (DFS) and overall survival (OS) rates in the SC group and LC group at 3 years, were, 84.9% versus 72.4% (P = 0.273) and 96.2% versus 87.2% (P = 0.510), respectively. The complete pathological response (pCR) rates in the SC group and LC group were, 25% versus 18.1% (the difference was not statistically significant, P = 0.375), respectively. However, the SC group had better node(N) downstaging compared to the LC group (P = 0.011). Conclusions There were no differences observed in DFS and OS between short-course radiotherapy and long-course chemoradiation, and both can be used as treatment options for patients with locally advanced rectal cancer.

Neoadjuvant radiation therapy is integral in the management of patients with localized rectal cancer. In parts of Europe, patients with operable rectal cancer are treated with short-course radiation therapy delivered in five daily, 5 Gy fractions to a total dose of 25 Gy, followed by surgery within 1 week. In the US, the standard for locally advanced rectal cancer is neoadjuvant chemoradiotherapy. This approach is principally based on the results of the German Rectal Cancer Study Group trial evaluating preoperative compared with postoperative chemoradiation. Surgery is typically performed at 4–8 weeks following completion of long-course chemoradiotherapy, facilitating tumor downstaging, and potential sphincter sparing surgery. No significant difference in clinical outcomes has been observed between these two approaches in two randomized clinical trials; however, further follow-up of these studies and new results from ongoing trials are anticipated to further clarify the optimal neoadjuvant treatment strategy.
