Predictive Ability of C-Reactive Protein in Detecting Short-Term Complications After Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: A Retrospective Cross-Sectional Study
Background: Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is a potentially curative treatment for peritoneal carcinomatosis. Objective: The aim of this study was to determine the predictive value of postoperative inflammatory biomarkers in assessing complications after CRS and HIPEC. Methods: A prospective database of 181 patients, who underwent CRS-HIPEC between March 2014 through April 2018 in the Erasmus MC, was retrospectively analyzed. Postoperative complications were defined according to the serious adverse event (SAE) grading system. Levels of C-reactive protein (CRP) and white blood cell (WBC) count were compared between patients with SAE grade < 3 and SAE grade ≥ 3. The area under the receiver operating characteristic curve (AUC) was calculated for CRP and WBC against SAE ≥ 3 and various intra-abdominal complications. Results: SAE ≥ 3 postoperative complications occurred in 50 patients. From the second until the fifth postoperative day (POD), CRP levels were significantly higher (p = 0.023, p < 0.001, p = 0.002, and p = 0.002, respectively) in these patients. CRP concentrations above 166 mg/L on POD3 (AUC 0.75) and 116 mg/L on POD4 (AUC 0.70) were associated with the highest risk of an SAE ≥ 3. Postoperative WBC levels were not significantly different between patients with SAE < 3 and SAE ≥ 3 complications. Conclusion: Data from our hospital suggest that CRP levels that continue to rise after POD2 or that are ≥ 166 mg/L at POD3 or ≥ 116 mg/L at POD4, indicate a considerable risk for developing high-grade SAEs. The cut-off values we found can potentially be used as a threshold for additional diagnostic interventions, after they have been validated in external data.
