The Bruton tyrosine kinase (BTK) inhibitor ibrutinib is effective in patients with chronic lymphocytic leukemia (CLL). Reasons for discontinuing therapy with this drug and outcomes following discontinuation have not been evaluated outside of clinical trials with relatively short follow-up. ⋯ This single-institution experience with ibrutinib confirms it to be an effective therapy and identifies, for the first time, baseline factors associated with ibrutinib therapy discontinuation. Outcomes data show poor prognosis after discontinuation, especially for those patients with RT. Finally, sequencing data confirm initial reports associating mutations in BTK and PLCG2 with progression and clearly show that CLL progressions are associated with these mutations, while RT is likely not.

Association of Actual and Preferred Decision Roles With Patient-Reported Quality of Care: Shared Decision Making in Cancer Care.
Shared decision making is associated with improved patient-reported outcomes of cancer treatment, but not all patients prefer to participate in medical decisions. Results from studies of the effect of matching between actual and preferred medical decision roles on patients' perceptions of care quality have been conflicting. ⋯ Physician-controlled decisions regarding lung or colorectal cancer treatment were associated with lower ratings of care quality and physician communication. These effects were independent of patients' preferred decision roles, underscoring the importance of seeking to involve all patients in decision making about their treatment.

Substantial progress has been made in cancer diagnosis and treatment, resulting in a steady improvement in cancer survival. The degree of improvement by age, race, and sex remains unclear. ⋯ Younger patients experienced greater benefit from recent oncology advances than elderly patients. African Americans experienced poorer survival than whites for all cancers, and the racial difference decreased for prostate cancer but increased for ovarian cancer. Identifying factors associated with varied improvement in cancer survival can inform future improvements in cancer care for all.

Many men with indolent prostate cancer often opt for radical prostatectomy or radiotherapy treatment for their disease. These men may experience considerable detriments of quality of life owing to sexual, urinary, and/or rectal toxic effects associated with these treatments. Without a better understanding of the mutable agents and predictors of treatment types, diffusion of expectant management among these men will be slow. ⋯ There is increased use of radiotherapy among patients with indolent prostate cancer with limited to no correlation with tumor biology. Active surveillance was underused, and a significant proportion of the variance was unexplained. Further research into qualitatively describing the contributing factors that drive decision-making recommendations for prostate cancer patients is needed.
