Combined therapy of psoralen plus ultraviolet A followed by narrow band ultraviolet B photochemotherapy for early stage mycosis fungoides / 中华肿瘤杂志

ABSTRACT

<p><b>OBJECTIVE</b>Only a few clinical reports in the treatment of early mycosis fungoides (MF)(IA, IB, IIA stage) are available in the literature. The purpose of this study was to compare the efficacy and safety of narrow-band UVB and psoralen plus ultraviolet A (PUVA) photochemoterapy in 24 patients with early-stage MF, and explore a new approach for the treatment of early mycosis fungoides.</p><p><b>METHODS</b>A total of 24 identified early mycosis fungoides patients received PUVA, NB-UVB and a combined therapy of PUVA followed by NB-UVB (n = 9/6/9) irradiation. A retrospective study was carried out to analyze the sex, age of onset, TNM stage, treatment, and duration of treatment, and times of treatment, duration of maintenance treatment, effective and recurrence in these patients. The data were analyzed using SPSS 17.0 and a two-sided test at the α = 0.05 level of significance was conducted.</p><p><b>RESULTS</b>Of the 24 patients studied, the average treatment was 104.5 (95% CI, 75.71-133.29) times. The average duration of treatment was 12.88 (95% CI, 9.90-15.85) months. The average maintenance treatment time was 11.08 (95% CI, 2.13-20.04) months. The effective rate (CR+PR) of PUVA treatment was 88.9%, recurrence rate was 11.1% (n = 9). In the NB-UVB treatment group, the effective rate was 100.0%, and the recurrence rate was 33.3% (n = 6). In the PUVA followed by NB-UVB (combination therapy) treatment group, the effective rate was 77.8% and the recurrence rate was 55.6% (n = 9). There were no significant differences among the three groups in terms of number of treatments, treatment duration, maintenance treatment duration, effective rate and recurrence rate (P > 0.05).</p><p><b>CONCLUSIONS</b>PUVA and NB-UVB are effective and safe in the targeted therapy of early stage mycosis fungoides. The combined therapy of PUVA followed by NB-UVB can reduce the total PUVA dose and risk of developing skin cancer.</p>
