Acute kidney injury after cytoreductive surgery and hyperthermic intraoperative cisplatin chemotherapy for malignant pleural mesothelioma

Abstract Objectives Cytoreductive surgery with hyperthermic intraoperative chemotherapy with cisplatin has been used successfully to treat malignant pleural mesothelioma, a highly aggressive malignancy that is rapidly fatal in most cases. We hypothesized that the combination of ischemic injury with nephrotoxic injury from cisplatin would result in high rates of acute kidney injury. Methods We conducted an observational study in 503 patients to study the risks and outcomes of acute kidney injury after surgical resection of malignant pleural mesothelioma. Eligible subjects underwent extrapleural pneumonectomy or pleurectomy/decortication with or without hyperthermic intraoperative chemotherapy. Acute kidney injury was defined as an increase in creatinine of 26.5 μmol/L or greater within 48 hours of surgery or a 50% or greater increase over 7 days. Results Acute kidney injury developed in 243 patients (48.3%). Severe acute kidney injury requiring renal replacement therapy developed in 16 patients (3.2%). Major significant predictors for acute kidney injury included male sex (odds ratio, 2.98; P  Conclusions Acute kidney injury is common after cytoreductive surgery with hyperthermic intraoperative chemotherapy with cisplatin and is associated with poor long-term outcomes. Strategies to prevent postoperative acute kidney injury are needed to improve multimodal treatment of malignant pleural mesothelioma.
