BackgroundIfosfamide has recently used as the intravenous component of bidirectional intraoperative chemotherapy (BDIC) with hyperthermic intraperitoneal chemotherapy (HIPEC) using cisplatin plus doxorubicin. Little is known about the systemic toxicities of this BDIC regimen. Therefore, this study aimed to assess the toxicities of this treatment.MethodsA prospective, cohort study, of patients who underwent the BDIC using intravenous ifosfamide 1,300 mg/m2 and a HIPEC regimen of cisplatin 50 mg/m2 plus doxorubicin 15 mg/m2, at King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia. Incidences and severity of leukopenia, neutropenia, thrombocytopenia, and erythrocytopenia were assessed over 45 days after BDIC. Nephrotoxicity was assessed according to the RIFLE (Risk, Injury, Failure, Loss of kidney function, and End-stage kidney disease) classification system. Haemorrhagic cystitis was assessed by cystoscopy.ResultsA total of 18 patients were enrolled in the study. Grade 1 leukopenia developed in 11.1% of the patients, with 5.5% developed neutropenia. Thrombocytopenia developed in 61.1% of patients; it was grade 1 or 2 in most patients, but grade 3 in 1 (5.5%) patient. All patients developed erythrocytopenia after BDIC. Leukopenia, neutropenia, and thrombocytopenia resolved without treatment in all patients. Nephrotoxicity developed in 33.3% of the patients. One patient progressed to the End-stage kidney disease classification. No patient developed haemorrhagic cystitis.ConclusionsIntravenous ifosfamide combined with HIPEC using cisplatin plus doxorubicin yielded low rates of mild leukopenia. Mild thrombocytopenia was frequent, but severe suppression of platelets was uncommon. Nephrotoxicity developed in one-third of the patients, and haemorrhagic cystitis was absent.
