| Description | Novel small molecule inhibitors have revolutionized the treatment of chronic lymphocytic leukemia (CLL). Indeed, BTK (BTKi) and BCL2 inhibitors (BCL2i) alone or in combination with each other or other compounds have proven superior to chemoimmunotherapy (CIT) in both the frontline and the relapsed/refractory (R/R) setting.1 ERIC, the European Research Initiative on CLL, conducted this international multicenter retrospective study focused on the era of CIT, aiming to (i) reveal the treatment patterns in the “real world” and (ii) assess the outcomes of patients who received frontline treatment between 2000 and 2016. Overall, 7382 patients with CLL (7134, 96.6%) or SLL (248, 3.4%) from 76 centers in 25 countries in five continents were included. The median age at diagnosis was 64 (interquartile range [IQR]: 56–71) years and the median age at first treatment was 66 (IQR: 58–74) years. The median follow-up was 7.33 (IQR: 4.56–10.81) years from diagnosis and 5.27 (IQR: 3.04–7.99) from first treatment. The vast majority of patients (6873/7134, 93.2%) received at least one line of chemotherapy or CIT; only 197/7134 (2.7%) received exclusively novel agents. Baseline characteristics and disease-specific biomarkers are listed in Supporting Information Material. The most common first-line regimen was FCR (2609, 35.3%), mostly in young patients (median age at first treatment: 60 years, IQR: 54–66), followed by chlorambucil monotherapy (1293, 17.5%), mostly in older patients (median age at first treatment: 74 years, IQR: 65–80). BTKis as first-line treatment were used in 149/7134 (2%) patients who either participated in clinical trials and/or had TP53 aberrations; 20/7134 (0.3%) received frontline venetoclax-based regimens, all in the context of clinical trials (Figure 1). Detailed outcomes for the most common frontline regimens are provided in Supporting Information Material. |
