Abstract:

Adult T-cell leukemia/lymphoma (ATL) cells are generally CD4+, CD8- and CCR4+. A 76-year-old man was diagnosed with a rare case of CD4-/CD8+ ATL in 2013. He was initially treated with the THP-COP regimen. The number of ATL cells in lymph nodes and peripheral blood (PB) and the level of soluble interleukin-2 receptor (sIL-2R) were decreased initially after chemotherapy but increased within 3 months and hypercalcemia appeared. Thus, the patient was diagnosed with ATL progression. Since CCR4 expression in CD4-/CD8+ ATL cells was confirmed by flow cytometry, the patient was treated with the newly developed CCR4 antibody mogamulizumab. Treatment significantly eradicated ATL cells in PB. To our knowledge, this is the first case of CD4- ATL treated with mogamulizumab.
