Abstract

Background: This study sought to evaluate the efficacy of a novel intraoperative chemotherapy (IOC) regimen that consists of hydroxycamptothecin, tumor necrosis factor (TNF), 5-fluorouracil (5-FU), and calcium folinate (CF) on the outcomes of colorectal cancer (CRC).

Methods: In total, 551 CRC patients who had undergone surgical resection were evaluated. Among these patients, 247 were treated with postoperative adjuvant chemotherapy, and 193 were treated with intraoperative chemotherapy. Of the CRC patients who underwent chemotherapy, 52 were treated with both postoperative adjuvant chemotherapy and intraoperative chemotherapy. Patients' characteristics, including age, sex, stage, differentiation, lymph node metastasis, surgical-pathological staging, tumor location, tumor size, and relapse-free survival, were collected.

Results: IOC for CRC therapy was associated with a more favorable survival prognosis (HR, 0.30, 95%CI, 0.19-0.48, P<0.001) independent of other clinical covariates. CRC patients treated with IOC survived longer than patients who were not treated with IOC did during surgery (P<0.0001, Kaplan-Meier log rank). Meanwhile, a Kaplan-Meier analysis demonstrated that individuals who received both IOC and POC survived longer than patients who received only POC: for stage II and stage III patients (P=0.0001, Kaplan-Meier log rank), stage II patients alone (P=0.02, Kaplan-Meier log rank), and stage III patients alone (P=0.046, Kaplan-Meier log rank).

Conclusions: The therapeutic effects of colorectal cancer by intraoperative chemotherapy with a novel regimen were enhanced, which improved the prognosis of patients with CRC.

Keywords: colorectal cancer, intraoperative chemotherapy, prognosis, therapy
