Platinum agents and mitomycin C-specific complications in cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC).

概要
BACKGROUND
Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been found to prolong survival in patients with peritoneal disease but is associated with significant morbidity. We evaluate the perioperative complications and the association with the chemotherapy agent used for HIPEC.
METHODS
Retrospective analysis of a prospectively collected database of CRS-HIPEC cases between April 2001 and February 2016 was performed. Patients were stratified by the chemotherapy used, and perioperative complications were compared.
RESULTS
Out of 214 CRS-HIPEC cases, 113 procedures used Mitomycin-C(MMC), 92 used cisplatin, 8 used oxaliplatin and the HIPEC regimen for one procedure was not recorded and excluded. 94 patients (44%) suffered low-grade complications (grade I-II), and 49 patients (23%) suffered high-grade complications (grade III-V). The frequency of low-grade complications for the cisplain, oxaliplatin and MMC groups were 49%, 50% and 40%, respectively, whereas that of high-grade complications were 24%, 50% and 20%, respectively. HIPEC with platinum agents was associated with a higher rate of acute renal impairment (ARI) compared to MMC (32% and 62% for cisplatin and oxaliplatin vs. 5.6% for MMC), whereas grade IV ARI requiring dialysis occurred only in the cisplatin group (5.6%). HIPEC with oxaliplatin was associated with higher rates of post-operative bleeding (25% vs. 1.1% and 0.88%). Rates of other complications did not differ significantly between the groups receiving different HIPEC regimens.
CONCLUSIONS
The overall complication rates do not significantly differ after HIPEC with MMC and platinum based agents. Renal impairment tends to be more common and of greater severity when a platinum agent is used, whereas oxaliplatin is associated with significant post-operative bleeding.
