Severe Neutropenia After HIPEC Using Mitomycin-C

Mitomycin-C (MMC) is the most commonly used chemotherapeutic agent for hyperthermic intraperitoneal chemotherapy (HIPEC) after cytoreductive surgery (CRS) to treat colorectal cancer patients with peritoneal metastases. However, MMC has a side effect of myelosuppression. Particularly, severe neutropenia after CRS with HIPEC can be a life-threatening condition. Despite the postoperative risks of this side effect, the causes and risk factors for severe neutropenia after CRS followed by HIPEC is not identified so far. Therefore, in this study, we aimed to evaluate to evaluate clinical risk factors and pharmacologic properties after CRS with HIPEC using MMC in patients with colorectal cancer or appendiceal mucinous neoplasms with peritoneal metastases.
