Randomized Controlled Trial Multicenter Study Comparative Study
Bosutinib Versus Imatinib for Newly Diagnosed Chronic Myeloid Leukemia: Results From the Randomized BFORE Trial.
Purpose Bosutinib is a potent dual SRC/ABL kinase inhibitor approved for adults with Philadelphia chromosome-positive chronic myeloid leukemia (CML) resistant and /or intolerant to prior therapy. We assessed the efficacy and safety of bosutinib versus imatinib for first-line treatment of chronic-phase CML. Methods In this ongoing, multinational, phase III study, 536 patients with newly diagnosed chronic-phase CML were randomly assigned 1:1 to receive 400 mg of bosutinib once daily (n = 268) or imatinib (n = 268). ⋯ Conclusion Patients who received bosutinib had significantly higher rates of MMR and CCyR and achieved responses faster than those who received imatinib. Consistent with the known safety profile, GI events and transaminase elevations were more common with bosutinib. Results indicate bosutinib may be an effective first-line treatment for chronic-phase CML.

Phase II Study of BGJ398 in Patients With FGFR-Altered Advanced Cholangiocarcinoma.
Purpose No standard treatment exists for patients with cholangiocarcinoma for whom first-line gemcitabine-based therapy fails. Fibroblast growth factor receptor 2 ( FGFR2) fusions/translocations are present in 13% to 17% of intrahepatic cholangiocarcinomas. BGJ398, an orally bioavailable, selective pan-FGFR kinase inhibitor, has shown preliminary clinical activity against tumors with FGFR alterations. ⋯ Grade 3 or 4 treatment-related adverse events occurred in 25 patients (41%) and included hyperphosphatemia (16.4%), stomatitis (6.6%), and palmar-plantar erythrodysesthesia (4.9%). Conclusion BGJ398 is a first-in-class FGFR kinase inhibitor with manageable toxicities that shows meaningful clinical activity against chemotherapy-refractory cholangiocarcinoma containing FGFR2 fusions. This promising antitumor activity supports continued development of BGJ398 in this highly selected patient population.

Soft tissue and bone sarcomas are malignancies of mesenchymal origin, and more than 50 subtypes are defined. For most sarcomas, locally advanced or unresectable disease is still treated with cytotoxic chemotherapy. Recently, our understanding of subtype-specific cancer biology has expanded, and it has revealed distinct molecular alterations responsible for tumor initiation and progression. ⋯ Although a subset of sarcomas appears inflamed and responsive to immune checkpoint blockade with programmed death 1 (PD-1) targeted agents, novel immunotherapies and combinations likely will be needed for most subtypes. A variety of approaches-including targeting immune checkpoints other than PD-1; modulating tumor-associated macrophage phenotype from tumor-promoting to tumor-suppressive status; using cellular-based therapies, such as chimeric antigen and high-affinity T-cell receptors to deepen the adaptive immune response; and reinvigorating older approaches, such as vaccines and oncolytic virus-based treatments-are being investigated. The goal of these new approaches is to harness subtype-specific insights into cancer and immune biology to bring more effective and less toxic treatments to the clinic for the benefit of patients with sarcoma.

Role of Patient Coping Strategies in Understanding the Effects of Early Palliative Care on Quality of Life and Mood.
Purpose The early integration of oncology and palliative care (EIPC) improves quality of life (QOL) and mood for patients with advanced cancer. However, the mechanisms by which EIPC benefits these outcomes remain unclear. We therefore examined whether EIPC improved patients' coping strategies and if changes in coping accounted for intervention effects on QOL and depressive symptoms. ⋯ The positive changes in approach-oriented coping, but not avoidant coping, significantly mediated the effects of EIPC on QOL (indirect effect, 1.27; 95% CI, 0.33 to 2.86) and depressive symptoms (indirect effect, -0.39; 95% CI, -0.87 to -0.08). Conclusion Patients with incurable cancer who received EIPC showed increased use of approach-oriented coping, which was associated with higher QOL and reduced depressive symptoms. Palliative care may improve these outcomes by providing patients with the skills to cope effectively with life-threatening illness.

Purpose Racial/ethnic disparities in cancer survival in the United States are well documented, but the underlying causes are not well understood. We quantified the contribution of tumor, treatment, hospital, sociodemographic, and neighborhood factors to racial/ethnic survival disparities in California. Materials and Methods California Cancer Registry data were used to estimate population-based cancer-specific survival for patients diagnosed with breast, prostate, colorectal, or lung cancer between 2000 and 2013 for each racial/ethnic group (non-Hispanic black, Hispanic, Asian American and Pacific Islander, and separately each for Chinese, Japanese, and Filipino) compared with non-Hispanic whites. ⋯ Conclusion Overall reductions in racial/ethnic survival disparities were driven largely by reductions for black compared with white patients. Stage at diagnosis had the largest effect on racial/ethnic survival disparities, but earlier detection would not entirely eliminate them. The influences of neighborhood socioeconomic status and marital status suggest that social determinants, support mechanisms, and access to health care are important contributing factors.
