Antitumor effects of human recombinant interferon-gamma and tumor necrosis factor on five cervical adenocarcinoma cell lines, in vivo and in vitro.
We examined the antitumor effects of recombinant interferon-gamma (IFN-gamma) and tumor necrosis factor (TNF) on cervical adenocarcinoma cell lines, in vitro and in vivo. Four of five cell lines showed a high sensitivity to IFN-gamma, in vitro. One of five cell lines showed a remarkable sensitivity to TNF, in vitro. Only one cell line resistant to both IFN and TNF was derived from a well-differentiated adenocarcinoma of endocervical type. Experiments using nude mice bearing transplanted tumors revealed that these cytokines were also effective against tumors in vivo. All these observations suggest that IFN-gamma or TNF can have positive effects in the treatment of patients with adenocarcinoma of the uterine cervix.
