Background

Treatments for early-stage mycosis fungoides (MF) include topical steroids, topical nitrogen mustard, topical bexarotene, narrowband ultraviolet B (NBUVB), psoralen plus ultraviolet A (PUVA), and local radiation. The relative cost-effectiveness of each treatment given the differences in treatment failure, disease progression, and therapy escalation is not established.

Objective

To compare the cost-effectiveness (CE) of treatment options for stage IA MF.

Methods

A state-transition model was constructed with health states of stage IA to stage IV disease, no MF, and death. Treatment-specific remission and relapse rates were obtained from the literature. Lifetime costs were calculated by accounting for medications, office visits, laboratory monitoring, related procedures, work absences, and travel.

Results

The order of CE of the study treatments was determined to be as follows: local radiation, $225,399 for 15.40 life-years (LYs); NBUVB, $344,728 for 15.17 LYs; PUVA, $371,741 for 15.07 LYs; topical corticosteroids, $469,354 for 14.65 LYs; topical nitrogen mustard, $951,662 for 14.29 LYs; and topical bexarotene, 11,892,496 for 13.55 LYs. Sensitivity analyses confirmed the CE rankings.

Limitations

We assumed a constant probability of response, relapse rates, and 3-month treatment intervals.

Conclusions

Local radiation is the most cost-effective treatment for limited local disease, whereas phototherapy (NBUVB or PUVA) is cost-effective for generalized disease. Our findings can serve to inform future studies and recommendations regarding selection of therapy for stage IA MF.
