Pelvic Exenteration with Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy (CRS plus HIPEC) for Rectal CancerCase Series with Review of Literature

Incidence of synchronous peritoneal metastases (PM) in colorectal cancer is approximately 5%, with another 5% of the patients develop metachronous PM. Colorectal PM has been hypothesized to be a loco-regional disease rather than a systemic spread, and cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has been considered as a viable treatment option. Pelvic exenteration is an established treatment option for locally advanced rectal cancer, but it is associated with significant morbidity. However, there are no studies evaluating the role of such procedure probably because the majority consider it as an exclusion criterion. Here, we present our experience with three cases of locally advanced rectal cancer with PM, treated successfully with pelvic exenteration and CRS-HIPEC.
