Abstract
BACKGROUND Malignant peritoneal mesothelioma (MPM) is an aggressive neoplasm with a poor prognosis. Bidirectional intraoperative chemotherapy (BDIC) using concurrent intraperitoneal and intravenous chemotherapy in combination with cytoreductive surgery (CRS) is an emerging treatment option for selected cases of MPM. It is a locoregional treatment that involves intraoperative chemoperfusion of heated chemotherapy. The administration of systemic along with intraperitoneal chemotherapy allows for a bidirectional chemotherapy gradient in peritoneal tumor cells. The aim of this treatment is eradication of microscopic residual cancer cells after major removal of macroscopic tumor nodules. To date, there is no consensus on the chemotherapeutic regimen that can be used in BDIC to manage MPM in patients with severe renal impairment. Administering intravenous ifosfamide with hyperthermic intraperitoneal cisplatin and doxorubicin is a promising regimen in treating peritoneal mesothelioma. Nephrotoxicity is a dose-limiting adverse effect of cisplatin and ifosfamide. Therefore, dose adjustment is required in patients with renal impairment. CASE REPORT In this report, we describe a 46-year-old female patient with recurrent MPM and severe renal impairment. Her treatment was managed with hyperthermic intraperitoneal cisplatin and doxorubicin along with intravenous ifosfamide following CRS. The cisplatin dose was reduced to 50% and the ifosfamide dose was reduced by 25%. The patient tolerated the procedure well, without deterioration in her renal function. At her 9-month follow-up, she did not report experiencing chemotherapy-related adverse effects, and her kidney function remained stable. CONCLUSIONS Severe renal impairment might not be a contraindication to using potentially nephrotoxic chemotherapeutic agents in CRS-BDIC.
