Photochemotherapy (PUVA) in the pretumour stage of mycosis fungoides: a report from the Scandinavian Mycosis Fungoides Study Group.

Fifty-one patients with mycosis fungoides of pretumour stage were treated with oral 8-MOP and UVA photochemotherapy (PUVA). Complete remission was induced within 2--3 months in 58% of the cases. Twenty-seven patients are still in remission on maintenance therapy 9--53 months after starting treatment. In 9 cases PUVA treatment was stopped due to therapeutic failure and in another 15 cases due to various side effects. Maintenance therapy was given weekly, monthly, or at even longer intervals. Maintenance at long intervals seems preferable.
