Intraperitoneal hyperthermic chemotherapy: experience at Baylor University Medical Center.
BACKGROUND
Patients with peritoneal carcinomatosis have a dismal prognosis despite systemic chemotherapy or palliative surgery. A novel strategy of complete tumor debulking with intraoperative hyperthermia with chemotherapy has been proposed to provide prolonged survival.


OBJECTIVE
To retrospectively analyze the preliminary experience with this technique at Baylor University Medical Center.


METHODS
All patients underwent attempted tumor debulking followed by intraperitoneal hyperthermia with 40 mg mitomycin-C over 2 hours.


RESULTS
Patient diagnoses included nonmucinous colorectal carcinomatosis (n = 9), diffuse peritoneal adenomucinosis (n = 1), peritoneal mucinous carcinomatosis (n = 2), and gastric carcinomatosis (n = 3). Tumors in most patients (13/15) were resected to < or = 5 mm, and those in 10 of 15 were resected to no gross disease. Complications included ileus (n = 9), bowel leak (n = 2), infection (n = 1), and fistula (n = 1). One patient died of progressive gastric cancer at 1 month. Within a median follow-up of 4 months, 8 patients had no tumor by radiologic or tumor marker analysis.


CONCLUSIONS
Intraoperative hyperthermia with chemotherapy is a viable treatment for patients with isolated peritoneal carcinomatosis from colorectal or gastric origin.
