Abstract
PURPOSE
Peritoneal metastasis (PM) is the life-threatening cause of colorectal cancer patients (CRC). Adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) plus cytoreductive surgery exhibited promising effects in preventing recurrence and increasing the survival of CRC patients. However, the outcomes of HIPEC on treating advanced CRC with risk of PM are still controversial. Here, we retrospectively examined the impact of HIPEC on preventing PM and its overall effects on patients with locally advanced CRC who underwent primary curative resection at our center.
METHODS
We retrospectively analyzed 45 patients diagnosed with locally advanced colorectal cancer (CRC) who underwent primary curative laparoscopic surgery with proactive hyperthermic intraperitoneal chemotherapy (HIPEC), in conjunction with adjuvant systemic chemotherapy at our center between 2019 and 2022. An additional 55 patients with locally advanced CRC who underwent similar surgery and received adjuvant systemic chemotherapy but did not undergo HIPEC during the same period were selected as the control group. Disease-free survival (DFS), overall survival (OS), and PM incidence were compared between patients with and without HIPEC.
RESULTS AND CONCLUSIONS
The cumulative PM incidence was 2.2% in the HIPEC group and 14.5% in the control group(P = 0.0347). No significant adverse effects were observed in the HIPEC group. Furthermore, Kaplan-Meier survival analysis showed that the HIPEC correlated to better DFS [hazard ratio (HR) 0.4670, 95% confidence interval (CI) 0.2305-0.9462; P = 0.0345] and extended the overall survival of CRC patients [hazard ratio (HR) 0.3978, 95% confidence interval (CI) 0.1684-0.9395; P = 0.0355]. Therefore, our data supports that adjuvant HIPEC can prevent peritoneal failure in CRC patients and improve both PFS and OS survival following primary curative resection.
