Chronic lymphocytic leukaemia has a very heterogeneous disease evolution. Prognostic factors of B-CLL overall survival have been extensively studied. However, much less is known about prognostic factors that can identify patients who will never develop an indication for treatment, at the time of their initial diagnosis. In this study we give an overview of variables that have a predictive value for treatment free survival. Subsequently, we try to develop a novel prognostic index, to address the question ‘who will never need treatment for B-CLL?’.
