Nineteen Zambian and 22 American patients with hepatocellular carcinoma were treated with Adriamycin every three weeks in intravenous doses ranging from 20-75 mg/m2 (depending upon their initial serum bilirubin levels). Four of 16 (25%) "good risk" Zambian and American patients who received 75 mg/m2 had objective responses, while in five additional patients there was evidence of either transient tumor regression or disease stabilization. In contrast three of 25 "poor risk" patients who received 20-60 mg/m2 had objective responses. Even in this latter group, however, transient, objective signs of tumor regression were noted in four patients. The results of the present study confirm previous reports suggesting anti-tumor activity for high doses of Adriamycin in hepatocellular carcinoma. Since those responses seen were generally incomplete and transient, further clinical trials of this agent used in combination or sequentially with other agents are indicated.

We investigated the effect of camptothecin and adriamycin on [3H]TTP incorporation and bleomycin-stimulated [3H]TTP incorporation in host liver and hepatoma nuclei of rats. Camptothecin neither stimulated nor inhibited incorporation in the regular nuclear incorporating system. Bleomycin stimulated incorporation to a much greater extent in host liver nuclei and slow-growing hepatomas than it did in the fast-growing hepatoma 7777. Addition of camptothecin to bleomycin stimulated incorporation of [3H]TTP even further. This camptothecin stimulation was slightly greater in hepatoma nuclei than it was in host liver nuclei. Adriamycin inhibited [3H]TTP incorporation in the regular system as well as the bleomycin-induced incorporation. Hepatoma nuclei were more sensitive to this inhibition than were host liver nuclei. Sucrose density gradients indicated that camptothecin caused DNA strand scissions in addition to those produced by bleomycin. Camptothecin alone produced some single-strand but no double-strand scissions. The action of bleomycin was dependent on sulfhydryl-reducing agents. Camptothecin could partially substitute for this requirement. Adriamycin did not produce DNA breaks as determined by neutral or alkaline sucrose density gradients. Despite complete inhibition of bleomycin-induced [3H]TTP incorporation, adriamycin did not prevent bleomycin-induced DNA breaks. The inhibitory effect of adriamycin might have been on the repair system.

Five permanent tumor cell lines derived originally from either a solid or an ascites biopsy of rat hepatoma exhibited differential sensitivities to bleomycin, Adriamycin, 1-beta-D-arabinofuranosylcytosine, hydroxyurea, 1-trans-(2)-chloroethyl)-3-(4-methoylcyclohexyl)-1-nitrosourea, and 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea. The cells were least sensitive to hydroxyurea and 1-beta-D-arabinofurano-sylcytosine, with some cell lines being almost totally resistant to these drugs. However, from 25- to 700-fold differences in survival were obtained between cell lines treated with either bleomycin or Adriamycin.

Eighty one patients (59 females, 22 males) with advanced solid tumors were treated with Adriamycin in doses of 40 mg/m2 body surgace daily, in two days cycles, with resting periods of 3 weeks. Overall response rate was 46% (37/81). In breast cancer response rate was 56% (13/23) and in ovarian cancer 48% (13/27). In various other tumors remission was observed in soft tissue sarcomas (3/8), thyroid cancer (1/7), osteogenic sarcoma (1/4), oesophageal cancer (2/4), lung cancer (2/4), bladder cancer (1/2) and hepatoma (1/2). In breast cancer patients, 2-7 month remission duration was observed (M equal to 4.5 month) and in ovarian cancer 1.5-5 month (M equal to 3.2 month). Adriamycin was also applied intrapleurally in 31 patients with malignant pleural effusions with a low response rate (26%). This modified schedule of Adriamycin administration showed a high antitumor activity in breast and ovarian cancer and in soft tissue sarcomas. Squamous cell carcinoma of the esophagus was also sensitive to Adriamycin therapy. The very low rate of myelosuppression and oral ulceration showed the decreased toxicity of this Adriamycin administration schedule.

In a Phase II clinical trial, 14 patients with histologically proven primary hepatocellular carcinoma were treated with adriamycin administered intravenously at a dose of 75 mg/m2 every 3 weeks. All 11 evaluable patients responded with 3 exhibiting complete tumor regression after two, three, and five courses of adriamycin respectively. The remission durations for these 3 were 3, 6, and 7 months, and their survivals were 8, 9, and 13 months, respectively. The median survival of the evaluable patients is 8 months (range 1-13 months). The side effects encountered included myelosuppression, anorexia, nausea, vomiting, and alopecia. Adriamycin seems to be an effective agent in hepatocellular carcinoma. Further trials are underway to test its true efficacy both singly and in combination with other drugs in the management of this tumor.

This study was designed to determine the effects of several antitimor anthracyclines, including Adriamycin and its analogs, carminomycin and marcellomycin, on the ultrastructure of nucleoli of Novikoff hepatoma cells. Adriamycin and carminomycin, which are structurally related, induce nucleolar segregation following the formation of conspicuous fibrillar centers. Marcellomycin did not induce formation of nucleolar fibrillar centers. Instead, numerous microspherules formed following treatment with marcellomycin; later complete nucleolar segregation developed. The microspherules were observed to be in various stages of extrusion from the nucleolar body. This microspherule "migration" appeared to be both time and drug concentration dependent. These results show that the rate and extent of nucleolar ultrastructural aberration may be related to structural differences of the various anthracyclines.

Four patients received intraarterial (ia) hepatic infusion and 10 received intravenous (iv) adriamycin for hepatocellular carcinoma. Four of each group are evaluable. The remaining 6 patients died within 14 days of intravenous therapy and are, therefore, considered nonevaluable. Patients received 2 to 9 courses of adriamycin every 3 weeks. One half of each group of evaluable patients had partial responses (pr). The group had pr for 22.5 weeks (range 8 to 37). The iv group had pr 27.2 weeks (range: 16 to 38.5). Mean survival was 21 weeks for nonresponders, and 43 weeks for responders. Intraarterial infusion did not protect patients from adriamycin toxicity. Cardiac and liver toxicity were not seen, but marrow and gastrointestinal toxicity developed at 1.2 X 10(-7)M adriamycin serum level. Adriamycin disappearance curves after ia and iv therapy were similar for similar bilirubin levels, and prolonged with hyperbilirubinemia. Ascites fluid did not accumulate detectable adriamycin. Pharmacokinetics are described in this report.

Line 10 guinea pig hepatoma cells are resistant to killing by antibody plus guinea pig complement but not by antibody plus human complement. Agents that increase (metabolic inhibitors) or decrease (hormones) the sensitivity of the cells to killing by antibody plus complement were examined for their effects on the chemical, physical, and enzymic composition of the cells. The effects of these agents on the chemical and enzymic characteristics of isolated plasma membrane and intracellular fractions of these cells were also measured. Adriamycin treatment resulted in a decrease in the amount of ribonucleoprotein and smooth endoplasmic reticulum isolated from the cells as compared to untreated cells. Hormone (insulin or hydrocortisone)-treated cells were enhanced in their yield of this fraction but were decreased in their yield of mitochondria as compared to controls. Generally, the drug-treated cells were decreased, whereas hormone-treated cells were enhanced, in protein, lipid phosphate, and total phosphate content, as compared to untreated controls. This pattern was also noted in the plasma membrane fraction of the cells and, in several cases, in intracellular membrane fractions. These data suggest that the protein, lipid phosphate, and total phosphate content of the plasma membrane and intracellular membranes of these cells may correlate with their ability to resist humoral immune attack.

A randomized, controlled clinical trial comparing the use of lipiodol-transcatheter arterial embolization (L-TAE) in the presence versus the absence of Adriamycin (ADR) for the treatment of hepatocellular carcinoma was conducted from August 1988 through September 1989. In all, 125 Japanese hospitals participated in this study and 289 patients were entered in the trial. The patients were randomly allocated into group A (L-TAE) or group B (L-TAE + ADR) by telephone registration. There was no significant difference in background factors between group A and group B. Additional treatment, including repeated TAE or hepatic resection, was given to 189 patients. Among the four endpoints analyzed, the rate of tumor reduction and lipiodol accumulation in the tumor did not significantly differ between the two groups. The 3-year survival values for groups A and B were 33.6% and 34.9%, respectively; the difference was not significant. The serum alpha-fetoprotein level, however, decreased to a significantly greater extent in the group that received ADR than in the group that did not (P < 0.05). This result suggests that ADR has some favorable additional effect in L-TAE for the treatment of hepatocellular carcinoma.

Dibutyryl cyclic AMP was administered to 7 cases with hepatocellular carcinoma and its tumor thrombosis in portal vein, combined with intraarterial infusion of Mitomycin C or Adriamycin with implanted reservoir. Among these cases, tumor regressed in 5 cases, and therapeutic effect on tumor thrombosis was observed in 4 cases. The median survival time after initial treatment was about 5 months in 5 cases of Vp3, and more than 18 months in 2 cases of Vp2. Reduction of liver dysfunction by cholinesterase and hepaplastin test was found in most cases, and no severe side effects were observed. It is suggested that dibutyryl cyclic AMP has an antitumor effect on hepatocellular carcinoma, especially on its tumor thrombosis in portal vein, and also may assist in recovery from liver dysfunction.
