Newer Clinical Strategies for Combining Interferon and Cytotoxic Agents Against Solid Tumours and Hematological Malignancies

The role of interferons in the treatment of cancer continues to evolve. Despite limited single agent activity against solid tumours, interferons now appear to have an important role as modulators of the activity of a variety of cytotoxic drugs. Clinical benefits have been observed for combinations of interferons and alkylating agents against low grade lymphomas, interferons and dacarbazine against malignant melanoma, and interferons and 5-fluorouracil against gastrointestinal and genitourinary malignancies. Further progress will depend on a grealer understanding of the biology of the interaction.
