Abstract

Studies were performed with a semisolid agar culture system to determine the in vitro sensitivity of human ovarian carcinoma to human leukocyte interferon (IFN-alpha) and standard chemotherapeutic agents (adriamycin, cis-platinum, hexamethylmelamine, melphalan, and velban). Growth in culture occurred in 67% of samples derived from ascitic fluid and 71% of these exhibited reduction in tumor colony number by greater than or equal to 25% in response to 300 units interferon/ml. The responsiveness of the ascitic fluid samples to interferon ran parallel to the overall responsiveness to the other agents tested. Sensitivity to interferon was not related to the histology or grade of the tumor or to the stage of the disease. As compared with cell suspensions prepared from ascitic fluid samples, solid tumor samples had markedly lower viability, 39% vs 89%, and had more tumor cells, 81% vs 28%. Also, colonies derived from solid tumor samples were less sensitive to interferon and more sensitive to cis-platinum and adriamycin than were ascitic fluid-derived colonies. Three of four ascitic fluid samples showed a reduction in tumor colony number of greater than or equal to 25%, whereas none of the solid tumor samples obtained from the same don...Continue Reading
