In 1975 we started a prospective study on oral methoxsalen photochemotherapy (PUVA) in cutaneous T cell lymphoma (CTCL). The first short-term follow-up of nineteen patients (1978) showed that PUVA may induce long-lasting remission in early stages, and that eventual relapses respond comparably well when PUVA is resumed. We now present the follow-up data of the original nineteen patients, covering a period of up to 7 years, and of an additional twenty-five patients who have entered the trial since April, 1977. Similar to earlier reports, all patients with eczematoid and plaque lesions (stages IA and IB) cleared. Likewise, eczematoid and plaque lesions in patients with early tumors (stage IIB) were cleared. During a mean follow-up of 44 months, 55% of stage IA patients and 39% of stage IB patients remained free of disease. In patients who experienced relapses, the mean disease-free interval was 20 months for stage IA and 17 months for stage IB. All patients with stage IIB experienced multiple relapses and only three of seven were alive after 6 years, despite additional x-ray or cytotoxic therapy. The observation in this study that five of nine stage IA patients and ten of twenty-six stage IB patients have remained in continuous remission after a single PUVA course for up to 79 months indicates that PUVA may induce long-lasting disease-free intervals if used in the early stage of disease. However, the observation period still does not prove whether permanent cure can be achieved in some cases or not.
