Abstract

Indomethacin has been shown clinically to inhibit growth of SCCHN (Panje, 1981). This inhibition appears to be due to augmentation of cellular immunity. The inhibitory effect of indomethacin may act by limiting tumor associated prostaglandin E2 production, thereby allowing return of costimulatory cytokines by antigen presenting cells. This would have the net result of relief from host unresponsiveness and promotion of B-cell and CTL differentiation, allowing the individual to mount an effective response. The enhancement of tumor infiltrating lymphocytes in SCCHN seen with indomethacin administration could presumably be further augmented when given in combination with cytokine therapy. Future investigation may allow the biochemical staging of an individuals' tumor to determine the optimal combination of cytokine therapy and prostaglandin inhibition through selective use of NSAID's. The effect of NSAID manipulation of prostaglandin and leukotriene metabolism on prevention of metastatic disease in SCCHN has yet to be studied. Given that a preselected, potentially responsive subset of immunocytes exists within the tumor tissue and lymph nodes, the development of the LAK phenomenon in TIL's and tumor draining lymph nodes from surgic...Continue Reading
