Cytoreductive surgery for hepatocellular carcinoma.

A prospective study was conducted on 26 patients for cytoreductive surgery of inoperable hepatocellular carcinoma. These patients underwent cytoreduction with liver resection, cryosurgery, microwave tissue coagulation and/or absolute alcohol injection. In-hospital mortality was 7.7%. The symptomatic relief and quality of survival were excellent. The median survival of patients after cytoreduction was 10.0 months and the survival was much better than those of 26 patients matched by sex, age, tumour size, Child-Pugh grading and Karnofsky scores who received systemic chemotherapy during the same period of the study (log rank test, P = 0.0001). There was no statistical difference between the survival curves of those patients who received (19 patients) and those who did not receive (7 patients) additional treatment by chemotherapy or selective internal radiation therapy after cytoreduction. This suggests that the gained survival benefit could have been derived mainly from the cytoreductive surgery rather than the additional treatments.
