Venetoclax combination regimen achieved excellent efficacy and safety in the treatment of relapsed/refractory multiple myeloma with t(11;14) in this case. The treatment of patients with relapsed and refractory multiple myeloma with t(11;14) by venetoclax still needs to be confirmed by more clinical studies.
These findings suggest that t(11;14)-positive AL amyloidosis constitutes a distinct biological and clinical subtype characterized by delayed treatment response to daratumumab. Tailored therapeutic strategies targeting the unique biology of t(11;14)-positive AL amyloidosis is warranted.
