ReviewTargeting B Cell Signaling in Chronic Lymphocytic Leukemia.
In recent years, a revolution in the management of chronic lymphocytic leukemia (CLL) has centered on the targeting of the B cell receptor (BCR) signaling pathway. Our improved understanding of the biology of cell signaling in CLL and the development of oral kinase inhibitors directed at the BCR pathway has led to the approval of two new agents and has the potential to radically change the treatment of CLL in both the relapsed/refractory and upfront settings. In this review, we will describe the underlying biology of the BCR signaling pathway. ⋯ We will highlight ongoing trials that are evaluating the use of combinations of these agents with standard chemotherapy. We will evaluate some of the emerging data regarding toxicity, potential off-target effects, and mechanisms of resistance to BCR signaling pathway blockade. Finally, we will highlight some of the next-generation BCR pathway inhibitors currently in development.

ReviewCardiac Imaging: Multimodality Advances and Surveillance Strategies in Detection of Cardiotoxicity.
Contemporary cancer management has increased the overall number of cancer survivors, but cardiotoxicity remains a subject of concern, which is a major cause of noncancer mortality among survivors. Among the potential cardiovascular complications, left ventricular (LV) systolic dysfunction is a poor prognostic factor. ⋯ However, the LVEF, as a diagnostic and predictive parameter, has significant limitations, which calls for more effective multimodality imaging strategies. This approach requires further study, but there is increasing available data in the literature, encouraging the combination of multimodality imaging parameters and techniques for early cancer therapeutic-related cardiac dysfunction (CTRCD) detection.

ReviewTelemedicine and Palliative Care: an Increasing Role in Supportive Oncology.
With the emergence of telemedicine as a routine form of care in various venues, the opportunities to use technology to care for the most vulnerable, most ill cancer patients are extremely appealing. Increasingly, evidence supports early integration of palliative care with standard oncologic care, supported by recent NCCN guidelines to increase and improve access to palliative care. ⋯ One barrier to use of telemedicine is the concerns with technology and technology-related complications in population that is often elderly, frail and not always comfortable with non-face-to-face physician care. There remain significant opportunities to explore this intersection of supportive care and telemedicine.

Improvements in early diagnosis and cancer treatments have contributed to high survival rates for many cancer patients. However, these patients often die of cardiovascular disease rather than recurrence of their cancer. ⋯ Estimating cardiovascular risk by using advanced imaging and monitoring of the cardiac biomarkers can be used for early detection and treatment of subclinical cardiac injury. Better knowledge of these early and late cardiac effects in cancer patients will enable adoption of both primary and secondary prevention measures of long-term treatment complications in cancer survivors.

ReviewThe Evolving Role of the Estrogen Receptor Mutations in Endocrine Therapy-Resistant Breast Cancer.
Recurrent ligand-binding domain ESR1 mutations have recently been detected in a substantial number of patients with metastatic ER+ breast cancer and evolve under the selective pressure of endocrine treatments. In this review, we evaluate the current understanding of the biological and clinical significance of these mutations. ⋯ Currently, we are lacking prospective studies to confirm these results and to determine the optimal treatment combinations for patients with the ESR1 mutations. In addition, the clinical development of novel agents to overcome resistance engendered by these mutations is also needed.
