Background: The aim of this study was to evaluate the prognostic value of preoperative sarcopenia with regard to postoperative morbidity and long-term survival in patients with peritoneal metastasis from colorectal cancer treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Methods: A longitudinal cohort study was conducted on patients with peritoneal metastases of colorectal origin treated with CRS–HIPEC between 2008 and 2018. Data on patient demographics, body mass index, operative characteristics, perioperative morbidity and survivorship status and oncological follow-up were obtained from the hospital registry. Sarcopenia was assessed using preoperative computed tomography (CT) findings. Results: Sixty-five patients [mean (SD) age: 54.4 (13.4) years, 64.6% females] were included in the study. Sarcopenia was evident in 30.8% of patients, while mortality rate was 66.2% with median survival time of 33.6 months. Presence of sarcopenia was associated with older age (59.6 (9.2) vs. 52.1 (14.4) years, p = 0.038), higher likelihood of morbidity (70.0% vs. 35.6%, p = 0.015) and mortality (90.0% vs. 55.6%, p = 0.010) and shorter survival time (17.7 vs. 37.9 months, p = 0.005). Cox regression analysis revealed that the presence of sarcopenia (HR 2.245, 95% CI 0.996–5.067, p = 0.050) was a significant predictor of increased likelihood of mortality. Conclusions: Preoperative sarcopenia is an independent prognostic factor of postoperative morbidity and shorter survival in CRC peritoneal metastasis patients treated with CRS–HIPEC. Our findings support the importance of preoperative screening for sarcopenia as part of preoperative risk assessment for better selection of CRS–HIPEC candidates or treatment modifications in CRC patients with peritoneal metastasis.
