PG - 135-143 LID - 10.1002/cncr.31738 [doi] AB - BACKGROUND: Laboratory testing and treatments for chronic lymphocytic leukemia (CLL) have changed dramatically within the last decade. The authors evaluated changes in patterns of real-world testing and treatment over time by comparing 2 population-based cohorts. METHODS: The National Cancer Institute-sponsored Patterns of Care study was conducted among patients with CLL who were sampled from 14 Surveillance, Epidemiology, and End Results (SEER) program registries. Demographics, testing, and treatment data were abstracted from medical records within 24 months of diagnosis. RESULTS: A total of 1008 patients diagnosed in 2008 and 1367 patients diagnosed in 2014 were included. There was a significant increase in fluorescence in situ hybridization (FISH) testing, immunoglobulin heavy-chain variable region gene (IgV(H) ) mutation analyses, and lymph node biopsies between 2008 and 2014. FISH testing was performed in the majority of, but not all, treated patients (53% in 2008, which increased to 62% in 2014). Some differences in the receipt of FISH testing by age and insurance status were observed over time (older patients and Medicare patients without private insurance were less likely to be tested in 2014). There were contrasting testing patterns noted by practice type and year, with nonteaching hospitals more likely to perform bone marrow biopsies in 2008, and teaching hospitals more likely to perform FISH and IgV(H) testing in 2014. There also were differences in treatments over time, with the use of bendamustine and rituximab being more common in 2014, at the expense of fludarabine, cyclophosphamide, and rituximab. CONCLUSIONS: There have been rapidly changing practices in the testing and treatment patterns of patients with CLL within the last decade. CI - (c) 2018 American Cancer Society.
