Core Tip

Core Tip: Tumor microenvironment (TME) combined with neoadjuvant chemotherapy (NCRT) is the standard treatment for resectable stage II/III rectal cancer (RC). Multiple classes of molecular biomarkers have been studied as potential predictors for RC response but there is no sufficient evidence for any of them to be introduced into clinical practice. By retrospectively evaluating clinical stage II/III RC patients undergoing NCRT followed by standard TME, we found that the combination of NCRT carcinoembryonic antigen and carbohydrate antigen 19-9 levels could be a prognostic predictor for clinical stage II/III RC patients receiving NCRT, and the combined indexes had a stronger predictive effect than the index alone.
