ReviewTherapeutic Approach to Patients with Chronic Lymphocytic Leukemia and Significant Comorbid Conditions.
Clinical trials in chronic lymphocytic leukemia (CLL) have focused mainly on younger fit patients until recently. However, CLL is a disease of elderly and many patients have significant comorbid conditions which together with advanced age preclude the use of aggressive regimens like FCR (fludarabine, cyclophosphamide, rituximab). Therefore, parameters such as performance status, renal function and number/severity of comorbidities together with clinical judgment should be used to guide the decision-making process regarding intensity of treatment. ⋯ Impressive efficacy of novel targeted small molecules interfering with B-cell receptor signaling, namely Bruton tyrosine kinase inhibitor ibrutinib and phosphatidylinositol-3 kinase delta inhibitor idelalisib, radically changed the treatment paradigms for relapsed/refractory CLL; relatively mild toxicity of these agents make them very good candidates for elderly/comorbid patients. Other options for relapsed/refractory disease include alemtuzumab, ofatumumab, high-dose glucocorticoids+rituximab and bendamustine+rituximab. This review summarizes the current knowledge on prognostication and therapy of elderly and comorbid patients with CLL.
