## Natural cell-mediated cytotoxicity has been shown to be age-dependent in both rats and mice. The present study was undertaken to study age-related levels of natural cytotoxicity in humans. Mononuclear peripheral blood cells from over 200 normal volunteers were co-incubated with 51Cr-labeled K-5

β¦ Synopsis
The contribution of natural cell-mediated cytotoxicity (NCMC) to tumor-directed cytotoxicity is unknown. This study was undertaken to correlate changes in NCMC to a single target cell (K-562) with responses to therapy in patients with small cell carcinoma of the lung, resectable stage I non-small cell carcinoma of the lung, and stage I and H melanomas. Data from these studies suggested that these patients have depressed levels of NCMC to 1(-562 compared with a normal age-matched control population. However, NCMC levels appear to fluctuate with tumor burden, being highest in patients with large tumor masses and lowest in patients with no clinical evidence of tumor following a successful response to therapy.
