    Abstract:
    In vivo studies aimed at therapy of spontaneous human tumor metastases have been hampered by the lack of practical experimental models. The LOX amelanotic melanoma model described here represents a transplantation model which rapidly and reproducibly results in spontaneous pulmonary metastasis following s.c. inoculation into athymic mice. Pulmonary lesions can be detected using a simple bioassay procedure which is useful for estimation of metastatic cell killing. Using this model we demonstrate that systemic therapy with cyclophosphamide or dacarbazine can produce metastatic cell killing consistent with complete eradication of established pulmonary metastases. This model may also prove useful for future experimental therapeutic studies aimed at prevention of metastases by manipulating tumor staging interval and treatment schedule.
