Efficacy and Side Effects of Narrowband-UVB in Early Stage Cutaneous T-Cell Lymphoma in Jordanian Patients.

Abstract

Background. Many studies, on light-skinned patients, suggested narrowband-UVB to be effective and safe for the treatment of early stage cutaneous T-cell lymphoma. Objectives. To evaluate the efficacy and side effects of narrowband-UVB in treatment of early stage cutaneous T-cell lymphoma in patients with skin phototypes III, IV, and V. Methods. A total of 27 patients with the diagnosis of early stage cutaneous T-cell lymphoma were involved in this prospective study. All patients received narrowband-UVB as monotherapy until clearance or a maximum of 42 sessions. Patients with complete clearance were followed for six months or relapse. Rate of clearance, number of sessions, and cumulative narrowband-UVB dose needed to achieve clearance, percentage of patients remaining in remission at 6 months, and side effects were analyzed. Results. Within 5-14 weeks (15-42 sessions), using cumulative narrowband-UVB dose ranging from 17.3 to 48.2 J/cm(2), complete remission was achieved in 76.4% of patients. The rest of the patients achieved partial remission. Six months after discontinuation of the treatment, 42.8% of patients with complete remission remained in remission. Transient erythema in 11.1% of patients and mild hyperpigmentation in 14.8% of patients were the only side effects encountered during this study. Conclusion. We conclude that narrowband-UVB phototherapy is safe and effective for the treatment of early stage cutaneous T-cell lymphoma in darker-skinned patients.
