    Abstract:
    The paper presents the results of experimental and clinical studies on the antitumor effect of larifan. A statistically significant inhibition of growth of some continuous mouse tumors by larifan in a dose of 2.5 mg/kg given for 5-6 days and by a combination of larifan with an immunomodulator, inosiplex, tested on hepatoma XXIIa which has a rather low sensitivity to larifan. The antitumor effect of larifan may be due to interferon production and immunomodulating effect. Treatment with 0.05% larifan ointment of patients with cervical dysplasia of moderate degree resulted in a significant increase of previously diminished production of alpha-interferon after 10-14 vaginal tampons and clinical cure in 88% of cases. A course of 8-10-day larifan monotherapy given before radial therapy resulted in a considerable improvement in patients with cervical cancer of II-III stages, and subsequently, for 1 1/2-month combined radial therapy, no significant changes in production of alpha-IF were observed. At the same time, in patients with cervical cancer treated by radial therapy alone a significant decrease of alpha-IF production by blood mononuclears was observed by the end of therapy.
