Conditions

Richter syndrome of chronic lymphocytic leukemia

Brief summary

The treatment will be considered effective if the combination enables the achievement of a minimum of 67% ORR at the end of the sixth cycle. Patients will be evaluated according to Lugano Criteria for aggressive lymphomas (Cheson et al. JCO, 2014). Residual underlying CLL may persist in node and/or marrow and still qualify as CR, denoting complete response of RT to treatment (Hallek M et al. IwCLL Criteria Blood 2008).
