Combination treatment with extracorporeal photopheresis, interferon alfa and interleukin-2 in a patient with the Sézary syndrome.

Extracorporeal photopheresis is generally accepted as standard therapy for the leukaemic and erythrodermic variant of cutaneous T-cell lymphoma, the Sézary syndrome (SS). Because of the limited efficacy in some patients with SS, combination therapy is often necessary. We report a new combination therapy for an intensively treated 62-year-old woman with advanced SS (T4N1BM1, stage IVb). Previous treatment with PUVA, retinoids alone and in combination with photopheresis, chlorambucil, and chemotherapy using cyclophosphamide, doxorubicin, vincristine and prednisone failed and were associated with significant side-effects. Six cycles of combination therapy with extracorporeal photopheresis, low-dose interferon alfa and interleukin-2 resulted in fading of the erythroderma and in a decrease of Sézary cells in the white blood cell count. The CD4/CD8 ratio decreased from 66 to 6 and the proportion of CD4 + CD7 – cells from 47% to 11%. Only mild side-effects such as influenza-like symptoms, fever and nausea were observed. Two months after this therapy, the patient developed enlarged lymph nodes without erythroderma, and died 1 year later from the lymphoma. Combination therapy with extracorporeal photopheresis, interferon alfa and interleukin-2 might be useful in selected patients with SS. [ABSTRACT FROM AUTHOR]
