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.

Interferon alpha (INF-alpha)--In systemic diseases, most indications for INF-alpha result from its effect on haematological or hepatological manifestations. The spectacular effect of INF-alpha in chronic myeloid leukemia has led to its use for the treatment of hypereosinophilia syndrome and systemic mastocytosis. Over the last 6 years, we have treated 7 patients with the hypereosinophilia syndrome who were resistant to corticotherapy and had markers of myeloproliferation. Although both hydroxyurea and INF-alpha can be effective alone, their combination led to a decrease in the eosinophilia count to 1,000/ml, a decrease which was long-lasting in most cases. INF-alpha is also used in histiocytosis X alone or in combination with retinoids or with etoposide and has been found effective in several observations. In carcinoid syndromes whether treated priorly or not with a 5-fluoro-uracil-streptozoticin combination, INF-alpha leads to an objective response in two-thirds of the patients. Several multicentric protocols are currently assessing the efficacity of INF-alpha in mixed cryoglobulinaemias. In most observations these cryoglobulinaemias are seen in patients with markers of hepatitis C (mainly HCV) and the early results are encouraging. Temporary improvement has been reported in discoid or subacute lupus in 8 out of 10 cases. Haemangiomas of the infant, when life-threatening and corticoresistant, may be a good indication for INF-alpha. Thus 20 newborns or infants (including 4 with Kasabach-Merrit syndrome) have been treated with good results in 18. Interferon gamma (INF-gamma).(ABSTRACT TRUNCATED AT 250 WORDS)
