Early progression of disease as a predictor of survival in chronic lymphocytic leukemia

We studied the prognostic value of early POD in a cohort of patients with CLL enrolled between 2010 and 2014 in the Connect CLL Registry. Overall, 829 eligible patients receiving first-line therapy were categorized into 3 groups: early POD (progression
