Prognostic Significance of Neoadjuvant Rectal Score and Indication for Postoperative Adjuvant Therapy in Rectal Cancer Patients After Neoadjuvant Chemoradiotherapy

The relapse-free survival subdivided by a combination of NAR score and postoperative adjuvant chemotherapy. The prognosis was significantly (p=0.038) better in the patients who received postoperative adjuvant therapy in the low NAR group (Figure 1A). Whereas, no difference existed between postoperative adjuvant therapy and survival in the high NAR group (Figure 1B). No correlation was observed between regimen and survival, based on the types of adjuvant chemotherapy regimen (Figure 1C, D).
