Impact of the extent and duration of cytoreductive surgery on postoperative hematological toxicity after intraperitoneal chemohyperthermia for peritoneal carcinomatosis.

Background: Peritoneal carcinomatosis (PC) is a major disease, currently treated using complete cytoreductive surgery and intraperitoneal chemohyperthermia (IPCH). Morbidity is a significant limitation of this procedure, usually related to the extent of surgery, and hematological toxicity, which is considered as dependent upon the chemotherapy dosage alone. The aim of our study was to investigate whether surgery alone had an impact on the hematological toxicity associated with the standardized drug protocol that we routinely prescribed.
