A 62-year-old man was found to have recurrent hepatocellular carcinoma (HCC) 2 cm in diameter in the left lobe in June 1990. After right lobectomy of the liver which contained the tumors of S6 2 cm and S8 3 cm in diameter 7 months before, the patient was treated with hepatic arterial embolization (TAE) combined with infusion of anti-cancer drug (ADM, CDDP) four times since June 1990. HCFU 300 mg per day was administered orally since June 1990. Since the 3rd TAE in December, 1990, the tumor stain in the left lobe disappeared for 10 months till October, 1991. No remarkable side effect of HCFU was noticed during this period. HCFU administration combined with TAE effectively prevented post-surgical recurrence of HCC in this case.

We established risk factors for high post-resectional recurrence in patients with hepatocellular carcinoma (HCC). They included: (1)Vp (+), (2)IM (+), (3)more than 5 cm in diameter of the main tumor, and (4)gross type except single nodular tumor. Seventy HCC patients in this category were divided into two groups. In group 1, 11 patients prophylactically underwent hepatic arterial infusion chemotherapy after liver resection. Chemotherapeutic agents (MMC, 5-FU, ADM, CDDP) with Lipiodol were administered 4 times a year via Infuse-A-port. The remaining 59 cases served as the control without prophylactic infusion. Two-year survival rate was better in prophylactic group (75%) than in the control (46%, p = 0.063). The two-year disease-free survival was significantly improved in group 1 (40%) compared with that in group 2 (26%, p = 0.019). Based on our data, we suggest that prophylactic arterial infusion chemotherapy can be efficacious in alleviating hepatoma recurrence after liver resection.

We formulated a new lipiodol-Adriamycin suspension (ADM/lipiodol, 50 mg/10 ml) that remained stable for 48 h (half-life, 25 +/- 3 days). In five cases of hepatocellular carcinoma (HCC) resected after intra-arterial infusion of this agent, the ADM concentration in the tumor was quite high and the tumor necrosis rate was more than 80% on histological examination. Over a 5-year period, 180 patients with unresectable HCC underwent transcatheter arterial embolization therapy (TAE) in the presence or absence of this agent. The regimens consisted of suspension injection alone (A, n = 54), suspension injection + TAE using gelatin sponge (B, n = 29), TAE followed by suspension injection (C, n = 34), and TAE alone (D, n = 63). The estimated 1-year survival values determined for patients treated with these regimens were 70%, 73%, 43%, and 39% respectively, and the corresponding 3-year survival values were 27%, 31%, 15%, and 10%. The survival achieved using suspension injection was thus superior to that obtained using conventional TAE, and combined therapy with suspension injection followed by TAE seemed to enhance survival, although there were some biases in tumor size and in the stage of tumor progression. For patients with tumors measuring 5 cm or more in diameter, the survival obtained using regimen A was lower than that achieved using regimen D, but the combination of TAE and suspension injection improved the 1-year survival value obtained using regimen D from 34% to 52%. For patients with tumors measuring less than 5 cm in diameter, the survival achieved using regimen A was markedly better than that obtained using regimen D, although no difference was found between the survival value achieved using regimen A and that obtained using regimens B and C. On the basis of these results, our newly formulated ADM-lipiodol suspension was surmised to be effective by itself against relatively small HCC tumors, whereas it enhanced the efficacy of conventional TAE in large lesions.

A 63-year-old male with four intrahepatic recurrences of surgically resected hepatocellular carcinoma was admitted to our hospital in June 1985. He underwent lateral segmentectomy of the liver in November 1983. Pathologic finding of Edmondson II with liver cirrhosis had been confirmed by the operative specimen. Sizes of four recurrent tumors were assessed by CT as 3.5 x 2.2 cm, 2.6 x 2.2 cm, 2.2 x 2.2 cm and 2.2 x 2.2 cm, respectively. During five years until July 1990, the patient was treated with hepatic arterial infusion of Lipiodol-anticancer drug suspension eight times (total 5-FU 900 mg, ADM 77 mg, MMC 73 mg, and Lipiodol 36 ml) and hepatic arterial chemoembolization of MMC microcapsules one time. In addition, two hepatic arterial infusions of CDDP (total 70 mg) were given and 5-FU (total 10 g) was administered intravenously. Partial response (PR) was obtained for 19 months. Hepatic arterial infusion of Lipiodol-anticancer drug suspension was given only once every 6 months, and he maintained a good quality of life for over four and half years. The man died in July 1990. In general, multiple intrahepatic recurrence of surgical resected hepatocellular carcinoma has a poor prognosis. Therefore it was considered that hepatic arterial infusion of this drug brought about the relatively long survival of more than five years.

The effect of postoperative arterial infusion therapy using implanted reservoir was evaluated in 28 cases of resected hepatocellular carcinoma which showed at least one of those findings as Vp (+), Vv (+), IM (+) and more than 5 cm in tumor diameter. Ten of them underwent arterial infusion therapy with combination ADM and CDDP after hepatic resection (IA group) and the rest underwent no regional chemotherapy (control group). The one-, two- and three-year cumulative disease-free survival rates between control group and IA group were 55.6% against 80.0%, 25.4% against 70.0%, and 16.9% against 37.3%, respectively. The one-, two- and three-year cumulative survival rates between control group and IA group were 71.8% against 90.0%, 51.8% against 70.0% and 41.5% against 56.0%, respectively, a difference that was not statistically significant. We suggest this therapy can prevent intrahepatic recurrence, although it does not improve prognosis. To achieve a better prognosis, a new arterial infusion chemotherapy more effective than this one must be developed.

Combination therapy with hyperthermia and immuno-targeting chemotherapy was studied using conjugate of anti-AFP-antibody and adriamycin on AFP producing hepatocellular carcinoma (HC-4) in nude mice. Experimental groups were designed as follows; A. Control B. Adriamycin alone C. Conjugate alone D. Hyperthermia alone E. Adriamycin and hyperthermia F. Conjugate and hyperthermia. Hyperthermia was performed immediately after administration of ADM-conjugate (8.0 mg/kg as ADM) or ADM alone (8.0 mg/kg). Heating in the water bath was continued for 30 minutes at 42 degrees C or 40 degrees C and drug was injected intraperitoneally. Hyperthermic therapy at 42 degrees C along with ADM-conjugate completely inhibited the tumor growth compared with others. The serum AFP was undetectable level. The effectiveness of this treatment was also histologically confirmed. Tumor concentration of ADM remained at a significantly higher level for a prolonged period comparing other groups. Growth of HC-4 was completely suppressed by the combination therapy of hyperthermia and immuno-targeting chemotherapy. One of the probable causes of this antitumor effect may be due to prolonged and high level of ADM concentration in the tumor.

Pharmacokinetic and imaging studies in 19 patients receiving liposome-entrapped adriamycin (L-ADM) were carried out within the framework of a Phase I clinical trial (Gabizon et al., 1989a). The formulation of L-ADM tested consisted of 0.2 microM-extruded multilamellar vesicles composed of egg phosphatidylcholine, egg-derived phosphatidyl-glycerol (PG), cholesterol, and ADM intercalated in the fluid lipid bilayer. Plasma clearance of total drug extracted from the plasma after L-ADM infusion followed a biexponential curve with a pattern similar to that reported for free ADM. The plasma concentration of drug circulating in liposome-associated from was also measured in a subgroup of seven patients. Liposome-associated drug was found to be rapidly cleared from plasma. Its ratio to non-liposome-associated drug appeared to correlate with liver reserve, with highest ratios in patients with normal liver function. Liposome clearance, as measured by the plasma concentration of PG in three patients was slower than the clearance of liposome-associated ADM, suggesting that liposomes lose part of their drug payload during circulation. To learn about the liposome organ distribution, imaging studies were carried out with 111Indium-deferoxamine labelled liposomes of the same composition. Liposomes were cleared predominantly by liver and spleen and to a lesser extent by bone marrow in seven out of nine patients. In two patients with active hepatitis and severe liver dysfunction, there was minimal liver uptake and increased spleen and bone marrow uptake. Except for one hepatoma patient, intrahepatic and extrahepatic tumours were not imaged by liposomes, suggesting that liposome uptake is restricted to cells of the reticulo-endothelial system (RES).(ABSTRACT TRUNCATED AT 250 WORDS)

Transcatheter embolization of the hepatic artery for hepatomas was performed with the use of Gelfoam and Lipiodol-ADM in 98 patients (Gelfoam 63 patients; Lipiodol-ADM 35 patients). The cumulative one-year survival rate was 52.9% for the Gelfoam group and 28% for the Lipiodol-ADM group. Response to hepatic embolization was most remarkable in the nodular type; CR was obtained in five patients and PR in 31 patients (response rate: CR + PR = 57.1%) in the Gelfoam group, with no CR and six PRs (response rate, 17.6%) in the Lipiodol-ADM group. Alfa-feto protein (AFP) decrease of more than 50% was observed in 78.1% of the Gelfoam group and 40% of the Lipiodol-ADM group. The side effects were transient and controlled with conservative treatment. Gelfoam seemed to be more effective in the treatment of hepatoma, but the damage to normal tissue was more severe with this embolic material.

Six cases of unresectable hepatic cancer in infant were treated with intra-arterial infusion therapy. The histological types were hepatoblastoma and hepatocellular carcinoma, 3 cases respectively. The clinical stages were 1 recurrent case in I, 1 in IIIA, 2 in IIIB and 2 in IV. Seldinger method and cannulation at laparotomy were employed in 4 cases and 2 cases, respectively. In the eldest case, a catheter with dual lumen reservoir developed in our department was inserted, making it possible to infuse drugs into hepatic artery and cutting off hepatic arterial blood flow temporarily. The anticancer drug used was ADM, CDDP, 5-FU, THP-ADM, and MMC; antiAFP-anticancer drug conjugate missile therapy was employed in 4 cases. According to image diagnosis, reduction or necrosis of tumor was observed in 5 cases. In all cases, AFP scores decreased. In 5 dead cases, 4 cases died of tumor enlargement (average survival time 16.3 months); 1 case died of DIC during chemotherapy. The other case could eventually undergo complete resection and is now alive. Intra-arterial infusion therapy seemed to be useful for patients of infant unresectable hepatic cancer.

Antitumor effect and reduction of tumor size by some cytokines as Biological Response Modifier have been demonstrated by various studies. Endogenous tumor necrosis factor is produced from macrophage. To increase the antitumor effect of transcatheter arterial embolization (TAE) in hepatocellular carcinoma (HCC), we treated 7 HCC patients with endogenous tumor necrosis factor (ETNF) which was induced by hepatic arterial injection of gamma-IFN (1.0-3.0 X 10(6) IU) as priming agent and OK-432 (2-5 KE) as triggering agent. TAE was performed with Lipiodol, ADM and gelatin sponge on 3-10 days after the induction of ETNF. TNF activity was detected in 2 cases and suspected to depend on the dose of gamma-IFN and OK-432. Serum alpha-Fetoprotein levels after the injection of ETNF began to decrease from 3-30 days in 5 patients and remained unchanged in 2 cases. Serum alpha-Fetoprotein levels after TAE with the induction of ETNF were decreased 1-5 months in 5 cases. Reduced size and low-density area on CT scan in 3 advanced cases after these procedures were no different from those of HCC patients treated with TAE alone. In one of two inoperable cases with a single mass lesion in the liver, CT scan after one more added TAE following these procedures showed a low-density area around the Lipiodol uptaking tumor, indicating obstruction of the peripheral portal vein. CT scan of another case revealed low density around Lipiodol in the tumor, which showed complete necrotic change. In all cases, middle-grade fever and hypotension were seen transiently, but these subsided by symptomatic treatment. The antitumor effect of TAE in HCC might be enhanced with ETNF induced by hepatic arterial injection of a low dose of gamma-INF and OK-432.
