[Effect of age, nutritional status and tumor extension on various immunologic parameters in cancer patients].

We studied cellular immune (total lymphocytes, lymphocytary populations and delay hypersensitivity skin tests) and humoral (immunoglobulins and complement) response, as well as nutritional status (anthropometric and biochemical para meters), antitumoral treatment. The effect of tumoral extension, nutritional status and age on immunity was assessed. We have demonstrated a poor relationship between the cellular immunological response and the extension of neoplasia, a moderate effect of age and a significant impact of nutritional status.
