Core Tip
Core Tip: This retrospective single-center study demonstrates that prophylactic sodium thiosulfate (ST) markedly reduces both the incidence and severity of acute kidney injury in patients undergoing cytoreductive surgery with oxaliplatin-based hyperthermic intraperitoneal chemotherapy for colorectal peritoneal carcinomatosis. Patients receiving ST showed significantly lower postoperative creatinine levels and fewer kidney injuries without an increased risk of other postoperative complications. These findings indicate a clear nephroprotective benefit in this setting and support consideration of ST in oxaliplatin-based hyperthermic intraperitoneal chemotherapy protocols, although future prospective studies are warranted to confirm these results.
