INTRODUCTION : Mycosis fungoides (MF) and Sézary syndrome (SS) are the most common subtypes of cutaneous T-cell lymphoma (CTCL). While MF generally follows an indolent course, a subset of patients will experience progressive and/or treatment-refractory disease. Sézary syndrome is an aggressive CTCL associated with high morbidity and mortality secondary to immune compromise and opportunistic infection. Although allogeneic hematopoietic cell transplant (allo-HCT) is currently the only available potentially curative treatment modality for MF/SS and is included in NCCN and ASTCT treatment guidelines, there is no published guidance regarding referral criteria, timing and allo-HCT approach to help guide clinicians caring for these patients.
METHODS : Delphi survey of 32 specialists in dermatology (n=9), transplant hematology/oncology (n=10), non-transplant hematology/oncology (n=8), and radiation oncology (n=5) from across the United States. Consensus required agreement of ≥75% of participants.
RESULTS : Sixteen consensus statements were generated on four topics: 1) criteria for referral for consideration for allo-HCT, 2) allo-HCT preparative regimens and procedures 3) disease status at the time of allo-HCT, and 4) multidisciplinary management in the pre- and post-transplant settings.
CONCLUSION : These clinical practice guidelines provide a framework for decision-making regarding allo-HCT for MF/SS and highlight areas for future prospective investigation.
