Popis: This study was planned to evaluate the efficacy and safety of preoperative capecitabine and oxaliplatin (XELOX) without radiation in patients with locally advanced lower rectal cancer.Patients with clinical stage II/III lower rectal cancer underwent three cycles of XELOX followed by radical surgery. The primary end-point was the R0 resection rate.Thirty-one patients were recruited between February 2012 and August 2014. The completion rate of neoadjuvant chemotherapy was 96.5% among the 29 patients who received it; the remaining two refused chemotherapy and underwent immediate surgery. Grade 3-4 adverse events occurred in nine patients (31%). All 29 patients who received chemotherapy underwent radical resection. The R0 resection rate was 96.5% among these 29 patients. Pathological complete responses were achieved in three patients (10.3%) and downstaging occurred in 13 (44.8%).This pilot study found that neoadjuvant XELOX for locally advanced lower rectal cancer is feasible and safe. This neoadjuvant treatment improved resection margin status.
