Morbidity and mortality of synchronous hepatectomy with cytoreductive surgery/hyperthermic intraperitoneal chemotherapy (CRS/HIPEC).

Abstract

BACKGROUND:

Liver resection in conjunction with partial colectomy for colon cancer is considered acceptable treatment for isolated metastasis to the liver. This method is unstudied in patients undergoing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for carcinomatosis due to colon cancer and high grade appendiceal cancer.

METHODS:

A retrospective chart review included patients from 2005 to 2016 undergoing CRS/HIPEC. Cancers other than colorectal adenocarcinoma and high grade appendiceal carcinoma were excluded. Patients were divided into hepatectomy and non-hepatectomy groups. Data was collected by chart review from electronic medical records to assess morbidity and mortality, as well as oncologic outcomes of included patients.

RESULTS:

The average patient age, length of stay, and sex were similar between groups. For those in the hepatectomy group, 80% underwent minor hepatectomy, and 20% underwent major hepatectomy. The comprehensive complication index (CCI) scores ranged from 0 (no complications), to 100 (death). The average CCI between study groups was similar (27.29 vs. 17.41, P=0.09). Hepatectomy was associated with a higher rate of Clavien-Dindo classifications (CDCs) of III or greater. Complications included pressor requirement, renal failure, blood transfusions, TPN, pleural effusions and leaks requiring drain placement, respiratory failure, UTI, new onset atrial fibrillation, wound infections, and death.

CONCLUSIONS:

Patients who underwent CRS/HIPEC and hepatectomy for colorectal and high grade appendiceal carcinomatosis had more severe complications at similar rates to non-hepatectomy patients. Complication rates should be considered when selecting patients for aggressive surgical intervention.
