Etoposide as a single agent in the treatment of mycosis fungoides: A retrospective analysis

Abstract

Several chemotherapy agents have shown efficacy in the treatment of mycosis fungoides (MF). In the literature, there is limited data on the use of single agent etoposide for MF. We aimed to retrospectively review our experience with single agent etoposide in the treatment of advanced-stage or refractory early-stage MF with focus on analyzing its efficacy and safety. We included 13 MF patients who were treated with single agent etoposide. Patients were identified through the Cutaneous T Cell Lymphoma Database of Indiana University that involves patients treated from 2006 to 2016. Overall nine patients (69%) responded to treatment. No complete response was identified. Median time to response was 12.5 weeks (range: 6–25.4). Median duration of response was 43 weeks (range: 5–60) and median time to treatment failure was 31.3 weeks (range: 12.4–230). Hematological toxicity was observed in eight patients including two patients with grade 4 neutropenia and/or lymphopenia leading to sepsis. Higher doses of etoposide were significantly correlated with higher grades of anemia, neutropenia or lymphopenia (p < .05). Our study demonstrates that etoposide is an effective treatment for MF and may be considered in selected patients with progressive MF who have failed other treatments.
