BACKGROUND: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is increasingly used in peritoneal carcinomatosis (PC) management. This modality is criticized for its high morbidity and mortality. We evaluate the morbidity and mortality of patients undergoing this procedure in our institution. METHODS: A review of our institution's database was performed. All patients who underwent CRS/HIPEC between July 2011 and March 2018 were divided into three groups: no, low-grade, and high-grade complications. Prognostic factors were determined with Cox regression, while morbidity risk factors were analyzed using multinomial logistic regression. RESULTS: 225 consecutive patients underwent CRS/HIPEC. The most common primary cancer types were colorectal (35.1%), appendiceal (25.8%), and ovarian (22.2%). Median age was 55 years old (range 14-77), and patients were typically female (68.0%). 38.7% developed low-grade complications and 14.7% had high-grade complications. No 30-day mortality was observed. Different tumor origins are associated with significant differences in overall survival (p < 0.001). Patients without complications had significantly better survival than those with high-grade complications (HR 0.35, 95% CI 0.15-0.81, p < 0.001). Males were more likely to develop low-grade complications (OR 3.30, 95% CI 1.31-8.30, p = 0.011). Intra-operative blood loss was associated with greater odds of developing any post-operative complications (OR 1.001, 95% CI 1.0003-1.002, p = 0.007; and OR 1.002, 95% CI 1.001-1.002, p < 0.001, for low and high grade, respectively). CONCLUSION: Presence of high-grade complication was associated with poorer survival in patients after CRS/HIPEC. Pre-operative careful assessment of patients is pivotal to ensure favorable patient outcome following this complex procedure.
