Aim. To estimate vorinostat efficacy in patients with relapsed/refractory mycosis fungoides and Sezary syndrome.

Materials & Methods. The total of 21 patients with refractory and progressive mycosis fungoides and Sezary syndrome receiving vorinostat 400 mg once daily were followed up from 2014 to 2017. The median age was 62 years (range 34–79). The male to female ratio was 10/11. The median number of various regimens of pre-study systemic treatment was 4 (range 1–7). Progressive disease were observed in 85,7 % of patients before administration of vorinostat and after mono- and polychemotherapy.

Results. The study group included 15 patients with mycosis fungoides and 6 patients with Sezary syndrome. Early stages of primary cutaneous T-cell lymphoma were diagnosed in 4 patients, the advanced stages in 17 patients. Seventeen patients received vorinostat treatment in monoregime; 4 patients were administered with vorinostat in combination with methotrexate or α-interferon. The median duration of vorinostat therapy was 6 months (range 1–38). Stabilization of the disease was observed in 47.6 % of cases, response to treatment in 38.1 % of cases (with 5 cases of complete response and 3 cases of partial response), and 14.3 % of patients had progression of the disease. The decrease of skin itching was reported in 38.1 % of patients; skin itching completely resolved in 28.6 % of cases. The adverse events required the vorinostat dose adjustment in 3 cases and treatment discontinuation in 3 cases. The total of 9 patients continue to receive vorinostat.

Conclusion. Vorinostat treatment was shown to be effective in patients with refractory and advanced mycosis fungoides and Sezary syndrome not responding to various types of external, mono- and polychemotherapy. The therapy with vorinostat was associated with higher life expectancy and improved quality of life.
