Development and Validation of a Prediction Model for Acute Kidney Injury Following Cisplatin-Based HIPEC in Patients With Ovarian Cancer: a Multi-center Retrospective Cohort Study

Ovarian cancer is the most lethal malignant tumor of the female reproductive system. Cytoreduction surgery(CRS) combined with chemotherapy is the primary method for treating ovarian cancer, and complete tumor resection is an important means to improve prognosis. It has been demonstrated that the use of cisplatin for hyperthermic intraperitoneal chemotherapy (HIPEC) following CRS can significantly improve the prognosis of some patients with ovarian cancer. However, HIPEC with cisplatin can lead to acute kidney injury (AKI), a serious complication that can seriously affect the patient's short- and long-term prognosis. NCCN guidelines recommend the use of sodium thiosulfate in all patients receiving HIPEC. This study intends to retrospectively collect clinical characteristics of patients to establish a prediction model for kidney injury, with a view to screening those at high risk of kidney injury for use of sodium thiosulfate for nephrotoxicity rescue in cisplatin HIPEC.
