- description
- Best clinical response was determined according to the National Cancer Institute (NCI) Clinical and Clinical plus (+) Radiological evaluations by central response assessment. Assessment of response was performed according to the NCI revised guidelines for the diagnosis and treatment of chronic lymphocytic lymphoma (CLL) with additional computerized tomography (CT) scan evaluation of lymphadenopathy. Per NCI guidelines, CR requires all of the following criteria at least 2 months after the last treatment: no lymphadenopathy (Ly)/ hepatomegaly/ splenomegaly/constitutional symptoms; neutrophils greater than (\>)1500 per microliter (/µL), platelets (PL) \>100,000/µL, hemoglobin (Hb) \>11.0 grams per deciliter (g/dL), lymphocytes (LC) (less than) \<4000/µL, bone marrow (BM) sample must be normocellular for age, \<30% LC.
