Combination of Hepatic Arterial Infusion Chemotherapy and Portal Vein Occlusion for Unresectable Hepatocellular Carcinoma

We tried a combination of percutaneous transhepatic portal vein embolization (PVE) or portal vein ligation (PVL) and hepatic arterial infusion chemotherapy (HAI, with or without a reservoir) or transcatheter arterial embolization (TAE) for five patients with hepatocellular carcinoma (HCC) in whom the tumors were not resected. The patients were from 50 to 70 years old, and all had cirrhosis. The tumors were classified as being in stage III or IV by the UICC classification. Three of the five patients underwent PVE and the other patients underwent PVL. Adriamycin (ADR), epi-Adriamycin (epi-ADR), mitomycin C (MMC), or mitoxantrone (MIT), or some combination was used during HAI. These combinations of therapy was effective for hepatic tumors in all patients, as judged by decreases in tumor size and serum levels of α-fetoprotein (AFP) after treatment. The combination of HAI and portal occlusion may be effective for unresectable HCC.

We investigated the usefulness of hepatic resection with preoperative transcatheter arterial embolization (TAE) and percutaneous transhepatic portal vein embolization (PVE) for advanced hepatocellular carcinoma (HCC) retrospectivel.Fifty-nine patients underwent hepatic resection and had portal thrombi (vp). Of the 59 patients, 28 underwent hepatic resection only (group N), 20 underwent hepatic resection with TAE (group A), and 11 underwent hepatic resection with TAEand PVE (group AP). The nonrecurrence survival rate for the patients in group AP was higher than in the other groups. Eight patients had vp in the first branch of the portal vein (vp3). Only two of these patients (both in group AP) survived long; in group AP, the vp was covered with the embolic material in the operative specimens. PVE seems to be useful not only as a preoperative treatment but also as one treatment for unresectable HCC.

巨大な門脈下大静脈短絡路を有する肝硬変併存肝細胞癌の切除例を経験した.経皮経肝門脈造影像上,傍食道静脈への側副血行路は存在しなかったが,拡張蛇行した下腸間膜静脈から下大静脈への側副血行路が確認され,大部分の門脈血は遠肝性に逆流していた.門脈圧は26cmH2Oで,ICGR15値32.6%,血中アンモニア値141μg/dlと高値を示していたが,肝性脳症の既往はなかった.術中,電磁流量計を用いて門脈および下腸間膜静脈の血流を測定するとともに,S5亜区域切除を施行したが,側副血行路の遮断は行わなかった.術後,血中アンモニア値は上昇せず,肝性脳症の発症および食道静脈瘤の進展もみていない.以上より,巨大な側副血行路を有する肝硬変併存肝細胞癌症例の手術に際して,シャント遮断による門脈圧の亢進ひいては他の側副血行路の増悪も考慮し,肝性脳症や消化管出血の既往がなければ,肝切除のみでもよいと考えられる.

症例は50歳,男性.発熱及び腹痛を主訴として当科受診.血清AFP値は62,100ng/mlと高値を呈し,各種画像診断法により脾転移および門脈本幹内腫瘍栓合併肝細胞癌と診断.oneshot動注療法を行ったが腫瘍の増大と脾静脈内腫瘍栓を認めたため,2回のTAEを施したところ著明な抗腫瘍効果が得られた.肝細胞癌の脾転移は稀であり,また脾静脈内腫瘍栓の報告例はない.原発巣のみならず転移巣においてもその輪出血管に腫瘍塞栓がみられたことは,腫瘍塞栓の形成機転を考える上で興味深い.またTAEが奏功したことより,脾転移巣および脾静脈内腫瘍栓は動脈により栄養されていると考えられた.進行肝癌に対するTAEの適応については論議のあるところであるが,本症例はその適応を考慮すれば,TAEが安全に且つ有効に行いうることを示唆するものと考えられる.
