BACKGROUND: The aim of this retrospective study was to compare the efficacy and safety of different phototherapeutic modalities in the treatment of cutaneous lichen planus (LP).
METHODS: We retrospectively analyzed the chart data of 53 patients with generalized LP who had been subjected to narrowband UVB (NB-UVB) or photochemotherapy (PUVA) between January 1997 and April 2020. Of these, 30 patients had received NB-UVB, 18 patients oral PUVA and 5 patients bath PUVA.
RESULTS: Fifty patients completed a full treatment course. The percentage of patients with a complete (>90% clearing) or good (51%-90% clearing) response was similar for NB-UVB versus PUVA (86.2% vs. 90.5%; P = 1.00). The number of exposures required for obtaining a complete or good response was also comparable for both treatment groups (NB-UVB: 28.9 ± 12.3 vs. PUVA: 25.4 ± 10.1; P = .209). Adverse events, in particular gastrointestinal upsets, were recorded in 26.1% of patients treated with oral PUVA while none were observed with NB-UVB.
CONCLUSION: The therapeutic outcome and the number of treatments required for achieving a complete or good response were comparable for NB-UVB and PUVA; however, PUVA therapy was associated with a substantially higher rate of moderate adverse events.
