...152 rectal cancer patients...received chemoradiotherapy and surgical resection. The neoadjuvant chemotherapy regimens consisted of capecitabine, CapOX (capecitabine and oxaliplatin), FOLFOX, and 5-fluorouracil (5-FU). TACC3 expression significantly decreased sensitivity to chemoradiotherapy [risk ratio (RR) = 2.236, 95% confidence interval (CI): 1.447-3.456; P = 0.001] and thus the pathological complete response rate (P = 0.001).
