Significant activity has been demonstrated in AIDS-related Kaposi's sarcoma, ovarian carcinoma, bladder carcinoma, malignant glioma, non-Hodgkin's lymphoma, chronic granulocytic leukemia, the carcinoid syndrome and hairy cell leukemia. Although these leads are promising, the research has only just begun.
