Interventions/Control_1
Patients are p.o. administrated a 300 mg/m2 dose of bexarotene once daily for 8 weeks.
Interventions/Control_2
Patients are p.o. administrated a 300 mg/m2 dose of bexarotene once daily for 8 weeks.
Patients are treated with psoralen baths preceding treatment with UVA radiation 5 times weekly. The initial dose of UVA was 0.5 J/cm2, dose increment of 0.5 J/cm2 each radiation. The maximum dose was 4.0 J/cm2.
The initial dose of narrowband UVB administered is 50-70% of the MPD or 0.5-0.7 J/cm2. The dose of NB-UVB for the subsequent NB-UVB sessions is elevated 20% increments with each successive treatment session. The maximum dose is 2.0 J/cm2.

Results
We conducted the comparative study on the efficacy and safety between the Targretin monotherapy and the Targretin/phototherapy combination therapy for CTCL. In the efficacy, no difference was observed in the therapeutic effect of the two therapies evaluated by mSWAT and PGA at 8 weeks, but the two therapies have been shown to have therapeutic effects. In the combination therapy, 4 subjects were diagnosed to be the complete response, and it was suggested that the combination therapy may have a high effect.

Baseline Characteristics
A total of 46 subjects (29 males and 17 females) were enrolled, and 7 subjects were excluded. Twenty-four subjects (15 males and 9 females) and 22 subjects (14 males and 8 females) were assigned to the Targretin monotherapy group and the Targretin + phototherapy combination therapy group, respectively. The mean age was 69.3 years. The mean duration of cutaneous T-cell lymphoma (CTCL) was 2.06 years. No significant difference was observed between the two groups in terms of CTCL type or any other baseline characteristics.

Adverse events
The adverse events (AEs) that were reported during the research treatment and follow-up period of this study were 120 cases in 24 subjects of the Targretin monotherapy group and 111 cases in 22 subjects of the Targretin + phototherapy combination therapy group, respectively. Of the AEs, 5 serious adverse events were reported in 5 subjects, respectively (hypertriglyceridemia, type 2 diabetes, acute cholecystitis, rhabdomyolysis and interstitial lung disease). In addition, adverse drug reaction were also reported in 87 cases in 24 subjects of the Targretin monotherapy group and 77 cases in 22 subjects of the Targretin + phototherapy combination therapy group, respectively. The serious adverse drug reactions were reported in 3 cases in 3 subjects, respectively (hypertriglyceridemia, rhabdomyolysis and interstitial lung disease).
Outcome measures
No significant difference was observed between the two groups in the response rate by mSWAT evaluation or any the PGA evaluation after 8 weeks, which are the primary endpoints of this study. No difference was observed between the groups regarding the time to response period based on the mSWAT evaluation, which was a secondary endpoint. In both the groups, mSWAT scores were decreased over time until the time of evaluation at 8 weeks, indicating a therapeutic effect on CTCL. In the mSWAT evaluation, the rate of the decreases from baseline at 8 weeks tended to be greater in the Targretin + phototherapy combination therapy group. There was a difference in the rate of change in mSWAT between the research institutions. In Nagoya City University Hospital, the decrease from baseline was observed in both the groups. However, in Osaka City University Hospital, but the decrease was not observed in any of the groups.
