Surgical results of spontaneously ruptured hepatocellular carcinoma.
Seventeen patients with ruptured hepatocellular carcinoma (HCC) underwent a hepatic resection from 1985 to 1992 at either Kyushu University Hospital or Iizuka Hospital in Japan. They all underwent elective surgical procedures except for one patient who experienced a repeated rupture during hospitalization. A comparative study between the patients with ruptured HCC and non-ruptured large HCC measuring more than 6 cm in size (n = 29) revealed that the 3-year disease-free survival rate of the ruptured HCC group was 14.5% which was worse than that of the non-ruptured group at 39.9%. There was no difference in the rates of peritoneal dissemination, distant metastasis or intrahepatic recurrence between the two groups. Regarding the intrahepatic recurrence pattern, widespread multinodular recurrence frequently occured in the ruptured patients, which was thought to be caused by the high incidence of venous invasion in the primary tumor. The intratumor pressure of the ruptured HCC appeared to be elevated and is considered to be one of the main reasons for the high incidence of venous invasion.
