This volume reviews advances in the field of human tumour immunology, particularly in relation to the potential for immune intervention in preventing or treating tumours. The editors and contributors, all leading workers in the field, survey advances in the understanding of the relationship between the cancer cell and the immune response. Chapters review in depth the function of immune surveillance and mechanisms of tumour immunity, the role of T lymphocytes and oncogenes in the immune response to cancer, and the potential for immunotherapy of cancer. New areas of tumour immunology are presented, including recent progress in the development of tumour vaccines with particular reference to melanoma. Up-to-date and authoritative, volumes in this series are intended for a wide audience of clinicians and researchers with an interest in the applications of biomedical science to the understanding and management of cancer.
