Breakthrough in Treating Severe Mycosis Fungoides and Sezary Syndrome with Allogeneic HSCT

Introduction: A groundbreaking case study has demonstrated the successful treatment of severe mycosis fungoides (MF) and Sezary Syndrome (SS) using allogeneic hematopoietic stem cell transplantation (HSCT) with a Flu-Bu regimen. This rare achievement highlights the potential for long-term remission in patients with refractory MF/SS. Visit https://www.hspioa.org/ for more cutting-edge research in hematology and oncology.

A Promising Treatment for MF/SS Mycosis fungoides and Sezary Syndrome are rare and aggressive forms of cutaneous T-cell lymphomas. Traditional treatments, such as electron beam therapy, interferon, and methotrexate, often provide only partial remission. However, a recent case study has reported complete remission following allogeneic HSCT in a 25-year-old female patient.

Key Findings from the Case Study:

• The patient presented with extensive cutaneous involvement and was unresponsive to conventional therapies.
• She underwent a conditioning regimen with busulfan (Bu9.6), fludarabine (Flu150), and rabbit anti-thymocyte immune globulin (rATG-F) before transplantation from an unrelated male donor.
• Chimerism levels were 90% on day 30 and 99% by days 100 and 180 post-transplant.
• By day 100, all cutaneous lesions disappeared, and Sezary cells were no longer detectable in peripheral blood.
• The patient remained in complete remission three years post-transplant without graft-versus-host disease.

External Medical Insights on HSCT for Cutaneous Lymphomas The American Society of Hematology (ASH) emphasizes the importance of individualized treatment approaches for T-cell lymphomas, recognizing HSCT as a viable option for high-risk patients.

Future Implications for Treatment This case reinforces the effectiveness of allogeneic HSCT in treating aggressive MF/SS. While myeloablative conditioning remains debated, reduced-intensity regimens show promise in achieving remission with lower transplant-related mortality risks. Further clinical trials are needed to establish standardized protocols.
