Genetically modified tumour cells producing cytokines such as IL-12 are potent activators of antitumour immune responses and a promising therapeutic modality when combined with chemotherapy. We examined whether IL-12-producing cellular vaccines can augment chemotherapy of HPV 16-associated murine tumours with cytostatic agent gemcitabine (GEM). Peritumoral administration of IL-12-producing tumour vaccines enhanced the effect of cytoreductive therapy with GEM in non-metastasizing murine carcinoma TC-1 and in metastasizing murine carcinoma MK16. Lung metastases in mice were substantially decreased. In surgical minimal residual tumour disease IL-12-producing tumour vaccine and GEM after MK16 tumour surgery also reduced tumour recurrences and metastases. Tumour inhibitory effects of GEM plus IL-12 were associated with high production of interferon-γ by splenocytes. IL-12-producing vaccine can thus enhance the effect of GEM chemotherapy in some HPV16-associated murine tumour models.
