Safety and feasibility of in-hospital early chemotherapy initiation after surgery in patients with stage II-IV colon cancer

Abstract

Although it is recommended to initiate postoperative chemotherapy for colon cancer within 8 weeks after surgery, the feasibility and impact of initiating chemotherapy before discharge after surgical resection has not been investigated.Patients with stage II-IV colon cancer who received postoperative chemotherapy were dichotomized into early (chemotherapy initiation before discharge) and control (chemotherapy initiation after discharge) groups. A multivariable logistic regression model was used to determine factors associated with delayed chemotherapy, defined as more than 6 or 8 weeks after surgery.From January 2004 to December 2012, of 729 patients with stage II-IV colon adenocarcinoma, 555 patients (76.1%) underwent postoperative chemotherapy. Of them, 181 (32.6%) patients were included in the early group. Time to initiation of chemotherapy was significantly shorter in the early group than in the control group (14.9 days vs 31.5 days, P.05).The strategy of initiating chemotherapy before discharge after surgery is safe and feasible and might reduce the potential delay in chemotherapy initiation in patients with colon cancer.
