Interferon-alpha, interferon-gamma and sizofiran in the adjuvant therapy in ovarian cancer--a preliminary trial.

The study included 24 cases of negative second-look laparotomy (SLL) after operation on ovarian cancer. 12 cases were treated with sizofiran and recombinant interferon-gamma before and after SLL and then with human lymphoblastoid interferon-alpha. The remaining 12 cases (controls) were followed up without any drug therapy after SLL. There were no recurrences in the treated group, but in 3 cases of the control group. Also significant difference in survival was noted in the treated group.
