Introduction: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) in patients with ovarian peritoneal carcinomatosis may be associated with a high postoperative morbidity. An early discrimination of postoperative complications is crucial for both improving clinical outcomes and proposing a safe discharge.
Material and methods: In a cohort of 122 patients with advanced ovarian cancer (FIGO III-IV), we analyzed the diagnostic performance of three systemic inflammatory markers (C-reactive protein, white blood cell count and systemic immune-inflammation index) between the 5th to 8th postoperative days to prediction postoperative infectious complications. An optimal cut-off value was established in order to discriminate between the group of patients who developed infectious complications or not during the postoperative period.
Results: The median peritoneal carcinomatosis index (PCI) was 15. The overall infectious morbidity was 25.4% (31 patients out of 122), of which, 32% (10 patients out of 31) had suffered severe postoperative complications (Dindo-Clavien III-IV). The most accurate results for detecting infectious complications were obtained by using C-reactive protein, which presented an excellent diagnostic performance, especially on the 7th and 8th postoperative days (AUC = 0,857 and 0,920; respectively).
Conclusions: These results support that it is safe to discharge patients with C-reactive protein concentrations lower than 88 mg/L and 130 mg/L, on the 7th and 8th postoperative days, respectively.
