Treatment options for ATLL are limited and often depend on the subtype of the disease. Conventional chemotherapy regimens, such as CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone), are commonly used but have limited success. Antiviral therapies like zidovudine in combination with interferon-alpha have shown some efficacy. In some cases, allogeneic stem cell transplantation offers a potential cure but comes with significant risks.
