In a proportion of patients with chronic lymphocytic leukemia (CLL), resistance to Bruton tyrosine kinase (BTK) inhibitors (BTKi) is attributed to acquired BTK/phospholipase C gamma 2 (PLCG2) mutations. However, knowledge regarding additional genetic lesions associated with BTK/PLCG2 mutations, and gene mutations in patients lacking BTK/PLCG2 mutations, is limited. ⋯ Longitudinal, targeted, multigene deep sequencing is informative for the clinical monitoring of mutational evolution in patients with CLL who are receiving BTKi.

Surgical and medical androgen deprivation therapy (ADT) strategies are comparable in their ability to suppress serum testosterone levels as treatment in patients with metastatic prostate cancer but differ with regard to cost and impact on quality of life. Medical ADT is associated with better long-term quality of life due to the flexibility of possible therapy interruption but comes with a higher cumulative cost. In the current study, the authors examined whether surgical ADT (ie, bilateral orchiectomy) was used differentially by race/ethnicity and other social factors. ⋯ Race/ethnicity, neighborhood SES, and insurance status appear to be significantly associated with receipt of surgical ADT. Future research will need to characterize other differences in initial treatments among men with advanced prostate cancer based on race/ethnicity and aim to better understand what factors drive the association between surgical ADT among men of Hispanic origin or those from areas with low neighborhood SES.
