Multiple Myeloma (MM) is the second most common hematological malignancy worldwide and the third most common in China. It originates from plasma cells in the bone marrow, which are "immune warriors" that normally synthesize antibodies to fight infection. When these cells become malignant, they proliferate uncontrollably, crowding out healthy cells and destroying bone and kidney functions. Due to its insidious onset and diverse symptoms, the misdiagnosis rate is as high as 50%

Recently, the international hematology journal Blood Advances published a prospective clinical study by Lu Daopei Medical Team, titled "Efficacy and safety of BCMA nanobody CAR T-cell therapy in relapsed or refractory plasma cell myeloma," reporting breakthrough clinical results of BCMA-targeted nanobody-based CAR-T cell therapy in heavily pretreated refractory/relapsed plasma cell neoplasms.
