Pulmonary perspective: immunology in diagnosis and treatment of lung cancer.
The combination of the limits encountered with current therapies and the increased knowledge of immunology have opened perspectives for the use of immunomodulators in the management of lung cancer patients. Both humoral and cellular immunity are now evaluated in diagnosis and treatment of cancer. Monoclonal antibodies (MoAbs) against tumour-associated antigens are now tested with various imaging techniques to improve detection and staging of lung cancer. MoAbs are also used in therapeutic clinical trials as: 1) mediators of immune effector function; 2) carriers of cytotoxic agents; 3) agents to block tumour growth factor; or 4) anti-idiotype vaccines. Immune effector cells, such as natural killer (NK) cells, T- and B-lymphocytes, macrophages, dendritic cells and neutrophils, are present either within or around tumours and are likely to play a role in cancer. These cells, either alone or with cytokines, could provide new efficient therapeutic approaches, particularly if immunosuppression is involved in tumour progression. In this context, most recent studies using immune cells and molecular bioengineering, could provide additional antitumoral effects. Finally, the discovery of several tumour rejection antigens has revived the dream of designing tumour vaccines and active specific immunotherapy.
