High-frequency ultrasonography in objective evaluation of the efficacy of PUVA and UVA 1 phototherapy in mycosis fungoides.

Abstract

The aim of the present study was to assess the effectiveness of UVA1 and PUVA therapy in treating patients with mycosis fungoides (MF) and to evaluate high-frequency ultrasonography (HF-USG) to monitor the clinical response of these patients. A total of 18 patients diagnosed with MF (stages I-IIA) underwent phototherapy, either UVA1 (6 cases) or PUVA (12 cases). Clinical response was evaluated according to modified Severity Weighted Assessment Tool (mSWAT) criteria and HF-USG (20 MHz). In the PUVA group, 50% of patients (6/12) achieved complete remission (CR) versus 33% (2/6) of patients in the UVA1 group. Before treatment, all subjects (100%) presented a subepidermal low echogenic band (SLEB) on HF-USG in the lesional skin. After phototherapy, the SLEB decreased significantly in all cases, with complete disappearance in 66% of cases. SLEB thickness was associated with disease severity and was wider in stage IIA patients than in stage IA and IB. These findings demonstrate that skin ultrasonography can be used to monitor treatment response in these patients. Moreover, HF-USG can quantify response, thus providing an objective measure of response that closely corresponds to scoring systems such as mSWAT used in routine clinical practice.
