Abstract:
Cytoreductive surgery (CRS) coupled with hyperthermic intraperitoneal chemotherapy (HIPEC) has become the standard of treatment for many cancers with peritoneal metastasis. Mitomycin-C (MMC), the most common chemotherapy utilized with HIPEC, is associated with neutropenia but the degree of hematologic toxicity is unclear when splenectomy is included as part of CRS with MMC. We present an interesting case of pancytopenia following treatment with HIPEC using MMC and comment on the possible role of splenectomy in exacerbating its cytotoxic effects. Our unique case highlights potential hematologic toxicity following MMC-HIPEC and splenectomy. It suggests that spleen removal may enhance toxicity profiles of chemotherapy such as MMC. Because MMC is the preferred agent of choice used in CRS-HIPEC, future studies should investigate optimal MMC dosing and patient selection when splenectomy is performed to balance survival benefit with hematologic toxicities.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
