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.

Serum carcinoembryonic antigen (CEA) concentration was found to be raised in 503 of 550 patients (91%) with bladder cancer, lymphoma of intestine, hepatocellular carcinoma, bronchogenic carcinoma, prostate cancer, cirrhosis of liver and bilharziasis. The degree of elevation was moderate in all patients except in 189 patients in whom values more than 20 ng/ml were recorded, of which 53 patients with bladder cancer and 118 patients with bilharziasis. The mean CEA value in the patients with cirrhosis in the non-tumorous liver was slightly higher than that in those without cirrhosis, but the difference did not reach statistical significance (P greater than 0.01). There was no correlation between serum CEA and alph-fetoprotein (AFP) levels in all patients except in patients with bladder carcinoma, hepatoma and bilharziasis.

In order to estimate end effects of chronic prolonged gammairradiation of dogs, an exposure of 80 animals to irradiation was terminated and they were followed up closely. Out of 80 animals 30 dogs (1st series) were irradiated for 3 years and 50 dogs (II series) for 6 years. The dogs were exposed to irradiation at doses of 21 to 190 rad per year. Out of the total number of animals 22 dogs died. Post-mortem examinations showed neoformations in 13 animals (7 malignant and 12 benign neoformations). The highest number of tumors developed in dogs of the II series (10 out of 11) one-two years after irradiation (6 malignant tumors--malignant pheochromocytoma of adrenals; malignant adenoma of the hypophysis: polymorphocellular sarcoma of the liver; leucomyosarcoma of the uterus; bladder cancer; breast cancer; and 10 benign tumors--pancreatic adenoma; liver angioma; 2 papillary adenomas of the prostate; 3 renal adenomas; lipoma; polyps of the gall-bladder). Animals of the 1st series displayed 3 neoformations (1 malignant tumor--bladder tumor and 2 benign tumorsliver hepatoma and spleen angioma) 4--5 years after irradiation.

The present experiment was undertaken to study what types of human cancers are responsive to the antiproliferative effects of suramin. The human malignant cells used were as follows: cervical cancer (HeLa), mammary cancer (MCF-7), bladder cancer (EJ), hepatoma (HuH-7, PLC/PRF/5), embryonal carcinoma (PA-1), in vitro transformed fibroblasts (KMST-6, SUSM-1, VA-13), five myeloma cell lines (KMM-1, KMS-5, KMS-11, KMS-12, RPMI 8226), Burkitt's lymphoma (Raji), acute promyelocytic leukemia (HL-60), chronic myelocytic leukemia (K562), Epstein-Barr virus nuclear antigen positive lymphoblastoid cells (KMS-9). The cells were treated with 25 to 100 micrograms/ml suramin for 72h. Proliferation of HuH-7 and two human myeloma cells (KMS-11 and KMS-12) was remarkably inhibited, and that of PA-1, PLC/PRF/5, KMST-6, two other myeloma cell lines (KMM-1 and KMS-5), Raji and HL-60, was moderately inhibited. In order to confirm part of the results obtained from in vitro experiments, in vivo experiments were also undertaken. The growth of HuH-7 cells transplanted subcutaneously into nude mice was significantly suppressed by intravenous injection of suramin. We discussed the possibility that certain types of human cancers, the growth of which seemed to be more or less dependent on polypeptide growth factors, might be sensitive to the antiproliferative effects of suramin.

Suramin, a polyanionic compound used clinically for the treatment of African trypanosomiosis and onchocerciasis, has been shown to inhibit the action of various growth factors such as platelet-derived growth factor, epidermal growth factor, fibroblast growth factor and transforming growth factor-beta to stimulate DNA synthesis of cells. Therefore, we investigated effects of suramin on cell proliferation of various types of human malignant cells in culture. Cell lines used were as follows: cervical cancer (HeLa), mammary cancer (MCF-7), bladder cancer (EJ), hepatoma (HuH-7, PLC/PRF/5), embryonal carcinoma (PA-1), and three in vitro transformed human fibroblast lines (KMST-6, SUSM-1, and VA-13). A serum-free defined medium, ASF103, was used when the effect of suramin on proliferation of cells was investigated. This culture medium contains only bovine serum albumin (0.1%), transferrin (5 micrograms/ml) and insulin (5 micrograms/ml) as peptide factors. On day 1, the drug was added to culture medium at the concentration of 25-100 micrograms/ml and 72-96 hr later, the number of cells was counted. The growth inhibition was expressed as the percentage of cells surviving after treatment of cells with suramin, with survival in the control condition representing 100 percent. Proliferation of HuH-7 cells was prominently inhibited and those of PA-1, PLC/PRF/5 and KMST-6 were moderately inhibited under the same conditions of treatment. On the other hand, other five cell lines were not responsive to up to 100 micrograms/ml suramin.

Two-dimensional echocardiography was used to study malignant metastatic neoplasms of the heart and great vessels in 20 patients, 13 males and seven females, whose ages ranged from 15 to 72 years. Five patients had lung cancer; two each had breast cancer, malignant melanoma, hepatoma and one each had gastric cancer, urinary bladder cancer, adrenocortical carcinoma, malignant lymphoma, angiosarcoma, fibrosarcoma, leiomyosarcoma; and two had cancers with unknown primaries. Tumor invasion was demonstrated echocardiographically in the left atrium in one each with breast cancer, fibrosarcoma and gastric cancer; in the right atrium in two with hepatomas; in the right atrium and right ventricle in one patient with adrenocortical carcinoma; in the left ventricle in one with lung cancer; and in the pulmonary artery in one with malignant melanoma. Massive pericardial effusion was observed in 11 of 20 patients; two with pericardial tumors including malignant lymphoma and lung cancer. We conjectured that metastatic tumors in the right cardiac cavities came through the inferior vena cava, and other tumors in the left atrium, left ventricle and pericardium developed from direct extension of the primary lesions. There was an 80% mortality of the patients during the observation period, and the average survival period after the diagnosis of cardiac metastases was 5.5 months. However, one patient was still living after two years of radiation therapy and chemotherapy. Echocardiography proved a useful, non-invasive means for the detection and follow-up observation of metastatic cardiac tumors.

Acute myeloblastic leukemia (AML) was diagnosed in a 54-year-old male, a chronic hepatitis B surface antigen (HBsAg) carrier, in June, 1983. Prompt remission was achieved, and maintenance and intensification chemotherapy were given for five years. He was readmitted in March, 1988 because of a mass in the liver and was diagnosed as having hepatocellular carcinoma (HCC). Curative right segmentectomy was performed in May, 1988. In December, 1988, transitional cell carcinoma of the bladder was discovered, and resected transurethrally. These secondary neoplasms, HCC and bladder cancer, were thought to be associated with the long-term chemotherapy given for the AML.

Four murine MoAbs, KM191(IgM), KM206(IgM), KM230(IgG1) and KM231(IgG1), against human gastric cancer were generated using mice which underwent tolerance treatment to stomach tissues. They exhibited very similar high reactivities to stomach adenocarcinoma cells and low reactivities to normal cells in both membrane binding assay and immunohistochemical analysis. Their antigens were neuraminidase and protease sensitive and existed as macromolecules (1,000Kd) in body fluids. Binding of each antibody was inhibited by the others and KM231 showed the highest binding avidity. When they were used to detect the antigens shed in ascitic fluids and pleural effusions of cancer patients, KM231 allowed the most efficient detection of the antigen. The above results indicated that the four MoAbs bound to closely related epitopes on the same antigen and that the nature of its high binding avidity enabled KM231 to show the greatest efficiency in the detection of the antigen in body fluids. KM231 was applied to serum diagnosis and gave high positive percentages in pancreatic cancer(86%), hepatocarcinoma(87%), gall bladder cancer(50%), and gastric cancer(34%), whereas in healthy persons (0%) and benign diseases except for hepatitis(29%) the percentages were low. KM231 was similar to NS19-9, but quite different from NS19-9 in the high positive percentages of hepatocarcinoma in serum diagnosis.

Two mouse monoclonal antibodies (MoAbs), KM-93 raised against human lung adenocarcinoma and KM-231 raised against human gastric cancer, were useful in serum diagnosis of several human cancer. KM-93 and KM-231 recognize sialyl Lex epitope and sialyl Lea epitope, respectively, expressed on glycoprotein and glycolipid. We established a new "cocktail" sandwich enzyme-linked immunosorbent assay system using the two MoAbs and the advantage of this assay system, which can simultaneously detect sialyl Lex and sialyl Lea antigens, is assessed in the present study. The new assay system is composed of a mixture of KM-93 and KM-231 as 1st antibodies and a mixture of biotinylated two MoAbs as 2nd antibodies. We evaluated the concentration of MoAbs and optimized it to gain high cancer-positivity. This assay system covered sialyl Lex positive and/or sialyl Lea-positive sera and gave a high rate of positive results in lung adenocarcinoma (62.3%), gastric cancer (32.5%), colon cancer (37.5%), pancreatic cancer (83.3%), bile duct and gall bladder cancer (66.7%) and hepatoma (76.9%), whereas positive results in healthy adults remained low. Positive results in benign diseases of lung (12.5%), pancreas (10.8%), gall bladder and bile duct (9.1%) were very low, but were higher in liver cirrhosis (33.3%), hepatitis and liver injury (34.8%). Simultaneous detection of two carbohydrate antigens, sialyl Lex and sialyl Lea was clearly superior to single detection.

In order to evaluate the combination therapy for liver and bile tract cancer, the effects of anticancer drugs and hyperthermia were observed using cultured human cancer cell lines. In the case of gall bladder cancer cell line (NOZ), combination of adriamycin and hyperthermia showed more effective inhibition for cell proliferation than MMC + hyperthermia and 5-FU + hyperthermia. Hepatocellular carcinoma cell line (JHH-4) showed remarkable inhibition of cell growth and secretion of albumin by combination treatment of adriamycin and hyperthermia. Morphologically, JHH-4 cells were enlarged and the nucleus was also enlarged with combination adriamycin and hyperthermia by phase contrast microscopy. Cytoskeleton of JHH-4 cells became irregular and intercellular borderline was unclear by plasma polymerization replica method (PPRM). The effects of BRM (OK-432 and TNF) on HCC cell lines was also investigated. OK-432 directly inhibited proliferation of JHH-4 cells. We observed internalization of OK-432 by JHH-4 cells with TEM and 16-mm movie. TNF showed various effects on human HCC cell lines. Proliferation of two cell lines was inhibited, and one tended to be enhanced after the addition of TNF to the medium. Hyperthermia influenced the effects of TNF to HCC cell lines. We think that this paper is a very significant study for improving the therapy for hepato-biliary cancers.
