Introduction: We examined patient characteristics, treatments, and outcomes of patients with transformed mycosis fungoides (tMF) from COMPLETE: a large, multicenter, prospective cohort study of peripheral T-cell lymphoma patients in the United States. Methods: Patients with tMF were enrolled in COMPLETE at the time of transformation. For this analysis, we identified patients with tMF with completed baseline, treatment, and follow-up records. Median survival was assessed using Kaplan-Meier methodology. Results: Of the 499 patients enrolled in COMPLETE, 17 had tMF. Median age was 61; 53% were male, 9 had elevated lactate dehydrogenase, and 9 had lymph node involvement. Approximately one-quarter of the patients were African American and 47% had CD30+ disease. Median time to transformation was 53 months. All patients received systemic therapy, with 19% receiving concomitant radiotherapy. Most patients (87%) received single agents, including liposomal doxorubicin, pralatrexate, and gemcitabine. Eight patients (50%) had reported responses to therapy. Median survival was 18 months. One- and 2-year survival rates were 56% and 44%, respectively. Conclusions: tMF often expresses CD30 and presents with lymph node involvement. Responses have been seen with single agents, but survival remains poor. Novel treatment approaches are urgently needed to improve outcomes.
