Abstract:
Purpose:This study aimed to evaluate current morbidity rates following cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with colorectal cancer and peritoneal metastasis.
Methods:A total of 42 patients who underwent CRS and HIPEC for colorectal cancer with peritoneal metastasis at a single tertiary referral center between January 2022 and December 2022 were included. Perioperative outcomes and postoperative complications were prospectively assessed.
Results:The mean peritoneal cancer index (PCI) was 16.0. The distribution of PCI scores was as follows: <10, 33.3%; 10– 19, 26.2%; and ≥ 20, 40.5%. Completeness of the cytoreduction (CCR) scores were as follows: 57.1% of patients achieved CCR-0, 16.7% achieved CCR-1, 7.1% achieved CCR-2, and 19.0% achieved CCR-3. The mean operation time was 9.1 hours, and the median hospital stay was 17.0 days. Postoperative complications occurred within 30 days in 47.6% of cases and between 30 and 60 days in 11.9% of cases. Reoperation within 30 days was required in 5 cases, and 1 patient died within 30 days. The most common complications were pleural effusion (5 patients), anastomosis site leakage (3 patients), and pneumonia (3 patients). Patients with higher PCI scores were more likely to experience complications (P = 0.038).
Conclusion:Although CRS and HIPEC are still associated with high morbidity and mortality compared to other colorectal surgeries, outcomes have improved with increased experience. These results suggest that the procedure is becoming a more acceptable treatment option over time.
