  • Interleukin-2 and interferon-alpha are pleiotropic immuno-activating cytokines with clinical efficacy in malignant melanoma. The anti-melanoma activity of these cytokines is believed to result from the triggering of lymphocyte-mediated killing of tumour cells. In ongoing clinical trials, histamine dihydrochloride is used as an adjuvant to IL-2 and IFN-alpha with a view to protecting lymphocytes from oxidative inhibition induced by tumour-infiltrating monocyte/macrophages. In this study, we have serially monitored mononuclear cells in peripheral blood and tumour biopsies from 13 patients with metastatic malignant melanoma treated under a protocol comprising histamine, IFN-alpha and low-dose IL-2. One complete and 3 partial responses were observed, while 3 patients had stable disease and 6 progressed. A trend towards a gradual increase in the absolute number of circulating CD56+/CD3- NK cells in patients maintaining stable disease during therapy was noted. In tumour tissues, the extent of leukocyte infiltration prior to treatment correlated with tumour response. Additional infiltration by NK cells (CD56+) and monocytes during treatment was seen only in responding patients. Patients with progressive disease exhibited a low density of leukocytes infiltrating tumour tissues at the onset of treatment as compared to the surrounding tissues. Our data indicate that the degree and localization of mononuclear infiltration before and during immunotherapy under this protocol may determine therapeutic anti-tumour responses.
