title: [Evaluation of transcatheter hepatic segmental or subsegmental infusion of SMANCS for treatment of hepatocellular carcinoma].
abstract: A total of seventeen patients with hepatocellular carcinoma (HCC), nineteen HCCs, who underwent as an initial treatment transcatheter hepatic segmental or subsegmental arterial administration of SMANCS alone for hepatocellular carcinoma (HCC), were studied to evaluate the efficacy and complication of that treatment. The initial treatments provided CR in eight patients (47%), and repeat administrations of SMANCS achieved CR in an additional four patients (24%). The initial treatment provided a dense deposit of Lipiodol in the twelve tumors (63%), in five of which Lipiodol was thereafter washed out in some portions of the tumor. Complete necrosis was obtained in nine (75%) of fourteen hypervascular tumors, and in two (40%) of five intermediately vascular or hypovascular tumors. Segmental or subsegmental administration of SMANCS was well tolerated with self-controlled abdominal pain or fever well responding to medication. Ascites was seen in three cases, and atrophy of the segment infused occurred in five patients. Cholinesterase significantly reduced at one week and one month, then recovered to baseline two to three months after initial treatment. The cumulative survival rates were 77% at 1 year, 66% at 2 years, and 53% at 5 years in the whole patients. The survival rate was 100% at 5 years in the Child A group. In the patients who obtained CR using SMANCS alone, the survival rates were 89% at 1 year, 74% at 2 years and 56% at 5 years. Although this method may transiently deteriorate hepatic function, segmental or subsegmental administration of SMANCS may be an excellent therapeutic method for treatment of HCC and promising for use in properly selected patients.
