Background: Provider experience, or clinical volume, is associated with improved outcomes in many complex healthcare settings. Despite increased complexity of anticancer therapies, studies evaluating physician-level experience and cancer treatment outcomes are lacking. Methods: A population-based study was conducted of older adults (aged ≥66 years) diagnosed with B-cell non-Hodgkin’s lymphoma in 2004 through 2011 using SEER-Medicare data. Analysis focused on outcomes in patients receiving rituximab, the first approved monoclonal anticancer immunotherapy. We hypothesized that lower physician experience using rituximab and managing its infusion-related reactions would be associated with early treatment discontinuation. A 12-month look-back from each initiation of rituximab was used to categorize physician volume (0, 1–2, or ≥3 initiations per year). Modified Poisson regression was used to account for provider-level correlation and estimated relative risk (RR) of early rituximab discontinuation (<3 cycles within 180 days of rituximab initiation). Cox proportional hazards were used to measure the impact of rituximab discontinuation on survival. Results: Among 15,110 patients who initiated rituximab with 2,684 physicians, 7.6% experienced early rituximab discontinuation. Approximately one-fourth of patients (26.1%) initiated rituximab with a physician who had no rituximab initiations during the preceding 12 months. Compared with patients treated by physicians who had ≥3 rituximab initiations in the prior year, those treated by physicians without initiations were 57% more likely to experience early discontinuation (adjusted RR [aRR], 1.57; 95% CI, 1.35–1.82; P<.001 for 0 vs ≥3, and aRR, 1.19; 95% CI, 1.03–1.37; P=.02 for 1–2 vs ≥3). Additionally, rituximab discontinuation was associated with higher risk of death (adjusted hazard ratio, 1.39; 95% CI, 1.28–1.52; P<.001). Conclusions: Lower oncologist experience with rituximab was associated with increased risk of early rituximab discontinuation in Medicare beneficiaries with non-Hodgkin’s lymphoma. Physician-level volume may be an important factor in providing high-quality cancer care in the modern era.

Background: Current guidelines recommend hydroxyurea (HU) as frontline therapy for patients with high-risk essential thrombocythemia (ET) to prevent thrombosis. However, little is known about the impact of HU on thrombosis or survival among these patients in the real-world setting. Patients and Methods: A retrospective cohort study was conducted of older adults (aged ≥66 years) diagnosed with ET from 2007 through 2013 using the linked SEER-Medicare database. Multivariable Cox proportional hazards regression models were used to assess the effect of HU on overall survival, and multivariable competing risk models were used to assess the effect of HU on the occurrence of thrombotic events. Results: Of 1,010 patients, 745 (73.8%) received HU. Treatment with HU was associated with a significantly lower risk of death (hazard ratio [HR], 0.52; 95% CI, 0.43–0.64; P<.01). Every 10% increase in HU proportion of days covered was associated with a 12% decreased risk of death (HR, 0.88; 95% CI, 0.86–0.91; P<.01). Compared with nonusers, HU users also had a significantly lower risk of thrombotic events (HR, 0.51; 95% CI, 0.41–0.64; P<.01). Conclusions: Although underused in our study population, HU was associated with a reduced incidence of thrombotic events and improved overall survival in older patients with ET.

The NCCN Guidelines for Palliative Care provide interdisciplinary recommendations on palliative care for patients with cancer. The NCCN Guidelines are intended to provide guidance to the primary oncology team on the integration of palliative care into oncology. The NCCN Palliative Care Panel's recommendations seek to ensure that each patient experiences the best quality of life possible throughout the illness trajectory. Accordingly, the NCCN Guidelines outline best practices for screening, assessment, palliative care interventions, reassessment, and after-death care.

Mutations in the RAS/RAF/MEK/ERK pathway leading to constitutive activation and uncontrolled cellular growth have been identified in various human malignancies, making this pathway a target for potential therapeutics. The activating BRAFV600E mutation is one well-characterized oncogenic mutation that has been described and targeted with clinical success in various malignancies, including melanoma and hairy cell leukemia. Although BRAF-directed treatments have yielded clinical benefit in a subset of tumor types, such as melanoma, thyroid cancer, and lung cancer, BRAF inhibition fails to confer a clinical benefit in colon cancer. Identification of patients for whom BRAF inhibition may produce clinically meaningful outcomes is imperative. The incidence of BRAF mutations in neuroendocrine carcinoma (NEC) is estimated to be 5% to 10%. A recent case series demonstrated benefit in targeting the BRAFV600E mutation in metastatic high-grade rectal NECs. Combination BRAF and MEK inhibition is known to yield improved outcomes compared with BRAF inhibition alone in melanoma. This report presents 2 patients with high-grade colorectal NECs who had different responses to treatment with combined BRAF/MEK inhibition after experiencing disease progression through first-line platinum-based chemotherapy. One patient experienced an excellent initial response to therapy before ultimately experiencing progression, and in the other patient initially had stable disease before eventually experiencing progression. These cases highlight the complicated role BRAF mutations play in gastrointestinal NECs, and the need for further research to identify not only patients who may benefit from BRAF-directed therapies but also strategies to avoid development of resistance.

The NCCN Guidelines for Palliative Care provide interdisciplinary recommendations on palliative care for patients with cancer. These NCCN Guidelines Insights summarize the NCCN panel’s discussions and guideline updates from 2013 and 2014. These include modifications/additions to palliative care screening and assessment protocols, new considerations for discussing the benefits and risks of anticancer therapy, and approaches to advance care planning. Recent updates focus on enhanced patient-centered care and seek to promote earlier integration of palliative care and advance care planning in oncology.

The NCCN Guidelines for Palliative Care provide interdisciplinary recommendations on palliative care for patients with cancer. These NCCN Guidelines Insights summarize and provide context for the updated guidelines recommendations regarding hospice and end-of-life (EOL) care. Updates for 2017 include revisions to and restructuring of the algorithms that address important EOL concerns. These recommendations were revised to provide clearer guidance for oncologists as they care for patients with cancer who are approaching the transition to EOL care. Recommendations for interventions and reassessment based on estimated life expectancy were streamlined and reprioritized to promote hospice referrals and improved EOL care.
