This study aims to investigate the prognostic role of complete metabolic response (CMR) on interim 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) in patients with breast cancer (BC) receiving neoadjuvant chemotherapy (NAC) according to tumor subtypes and PET timing. ⋯ CMR indicated a significantly better outcome in BC and may serve as a favorable imaging prognosticator. The Oncologist 2017;22:526-534 IMPLICATIONS FOR PRACTICE: This study shows a significantly better outcome for breast cancer (BC) patients who achieved complete metabolic response (CMR) on 18F-fluorodeoxyglucose emission tomography/computed tomography (PET/CT) during neoadjuvant chemotherapy, especially for hormone receptor-positive tumors and triple negative BC. Moreover, PET/CT performed during an early- or mid-course neoadjuvant therapy is more predictive for long-term survival outcome than a late PET/CT. These findings support that CMR may serve as a favorable imaging prognosticator for BC and has potential for application to daily clinical practice.

Human epidermal growth receptor 2 (HER2) targeted therapies have survival benefit in adjuvant and metastatic HER2 positive breast cancer but are associated with cardiac dysfunction. Current U.S. Food and Drug Administration recommendations limit the use of HER2 targeted agents to patients with normal left ventricular (LV) systolic function. ⋯ LV dysfunction in patients with breast cancer poses cardiac and oncological challenges and limits the use of HER2 targeted therapies and its oncological benefits. Strategies to prevent cardiac dysfunction associated with HER2 targeted therapy have been limited to patients with normal LVEF, thus excluding patients who may receive the highest benefit from those strategies. SAFE-HEaRt is the first prospective pilot study of HER2 targeted therapies in patients with reduced LV function while on optimized cardiac treatment that can provide the basis for clinical practice changes. The Oncologist 2017;22:518-525 IMPLICATIONS FOR PRACTICE: Human epidermal growth receptor 2 (HER2) targeted therapies have survival benefit in adjuvant and metastatic HER2 positive breast cancer but are associated with cardiac dysfunction. To our knowledge, SAFE-HEaRt is the first clinical trial that prospectively tests the hypothesis that HER2 targeted therapies may be safely administered in patients with mildly reduced cardiac function in the setting of ongoing cardiac treatment and monitoring. The results of this study will provide cardiac safety data and inform consideration of clinical practice changes in patients with HER2 positive breast cancer and reduced cardiac function, as well as provide information regarding cardiovascular monitoring and treatment in this population.

On May 17, 2016, after an expedited priority review, the U. S. Food and Drug Administration granted accelerated approval to nivolumab for the treatment of patients with classical Hodgkin lymphoma (cHL) that has relapsed or progressed after autologous hematopoietic stem cell transplantation (HSCT) and post-transplantation brentuximab vedotin (BV). ⋯ Food and Drug Administration marketing application for a programmed cell death 1 inhibitor in hematologic malignancies. The use of immune checkpoint blockade in cHL represents a new treatment paradigm. The safety of allogeneic HSCT after nivolumab requires further evaluation, as does the safety of nivolumab after allogeneic HSCT.

No population-based longitudinal studies on end-of-life (EOL) expenditures were found for cancer decedents. ⋯ Taiwanese cancer decedents consumed considerable National Health Insurance disbursements at EOL, totaling more than was consumed in six developed non-U.S. countries surveyed in 2010. To slow increasing cost and improve EOL cancer care quality, interventions to ensure appropriate EOL care provision should target hospitals and clinicians less experienced in providing EOL care and those who tend to provide aggressive EOL care to high-risk patients. The Oncologist 2017;22:460-469Implications for Practice: Cancer-care costs are highest during the end-of-life (EOL) period for cancer decedents. This population-based study longitudinally examined EOL expenditures for cancer decedents. Mean annual EOL-care expenditures for Taiwanese cancer decedents increased from U.S. $49,591 to U.S. $68,773 from the year 2000 to 2010, with one third of spending in patients' last month and more than for six developed non-U.S. countries surveyed in 2010. To slow the increasing cost of EOL-cancer care, interventions should target hospitals/clinicians less experienced in providing EOL care, who tend to provide aggressive EOL care to high-risk patients, to avoid the physical suffering, emotional burden, and financial costs of aggressive EOL care.

Review Meta Analysis
Safety and Tolerability of PD-1/PD-L1 Inhibitors Compared with Chemotherapy in Patients with Advanced Cancer: A Meta-Analysis.
Compared with chemotherapy, significant improvement in survival outcomes with the programmed death receptor-1 (PD-1) inhibitors nivolumab and pembrolizumab and the programmed death-ligand 1 (PD-L1) inhibitor atezolizumab has been shown in several types of advanced solid tumors. We conducted a systematic review and meta-analysis to compare safety and tolerability between PD-1/PD-L1 inhibitors and chemotherapy. ⋯ PD-1/PD-L1 inhibitors are overall better tolerated than chemotherapy. Our results provide further evidence supporting the favorable risk/benefit ratio for PD-1/PD-L1 inhibitors. The Oncologist 2017;22:470-479 IMPLICATIONS FOR PRACTICE: We conducted a systematic review and meta-analysis to compare summary toxicity endpoints and clinically relevant adverse events between programmed death receptor-1 (PD-1)/programmed death-ligand 1 (PD-L1) inhibitors and chemotherapy. PD1/PD-L1 inhibitors were associated with a lower risk of treatment-related symptoms (fatigue, anorexia, nausea, diarrhea, constipation, and sensory neuropathy) but a higher risk of immune-related adverse events (AEs). Summary toxicity endpoints favor PD1/PD-L1 inhibitors (any all- and high-grade AEs and treatment discontinuation). PD1/PD-L1 inhibitors are overall better tolerated than chemotherapy. In addition to efficacy data from trials, our findings provide useful information for clinicians for well-balanced discussions with their patients on the risks and benefits of treatment options for advanced cancer.
