Article Synopsis
  • Aggressive end-of-life (EOL) care for cancer patients often results in more hospitalizations and a poorer quality of death, while effective goals of care (GOC) discussions can lead to fewer hospitalizations and increased hospice use.* -
  • A study at an academic cancer center found that less than half of patients had documented GOC discussions, despite those discussions being linked to higher rates of hospice enrollment and lower hospitalizations.* -
  • It’s suggested that hematology-oncology fellowship programs should enhance communication skills training to improve the quality of GOC documentation and EOL care for patients.*

Introduction: Definitive radiation therapy is considered standard therapy for medically inoperable early-stage NSCLC. Nevertheless, for patients with tumors located near structures such as the proximal tracheobronchial tree, esophagus, heart, spinal cord, and brachial plexus, the optimal management regimen is controversial. The objective was to develop expert multidisciplinary consensus guidelines on managing medically inoperable NSCLC located in a central or ultracentral location relative to critical organs at risk.

Navitoclax (ABT-263) is an oral BCL2 homology-3 mimetic that binds with high affinity to pro-survival BCL2 proteins, resulting in apoptosis. Sorafenib, an oral multi kinase inhibitor also promotes apoptosis and inhibits tumor angiogenesis. The efficacy of either agent alone is limited; however, preclinical studies demonstrate synergy with the combination of navitoclax and sorafenib.

Purpose: Delays initiating cancer therapy are increasingly common, impact outcomes, and have implications for health equity. However, it remains unclear (1) whether patients' beliefs regarding acceptable diagnostic to treatment intervals align with current guidelines, and (2) to what degree psychological factors contribute to longer intervals. We conducted a qualitative study with patients and cancer care team members ("providers").

Purpose: Current diagnostic methods to determine programmed death 1 (PD-1) receptor and its ligand (PD-L1)/PD-1 immunotherapy (immune checkpoint inhibitor [ICI]) efficacy in recurrent or metastatic non-small-cell lung carcinoma (rmNSCLC) are imprecise. Although previously shown that patients with high tumor PD-L1 (≥ 50%) demonstrate clinical benefit in the form of disease reduction and improved survival, patients with low PD-L1 (< 50%) sometimes benefit from treatment. Since the PD-L1/PD-1 pathway is dynamic, monitoring PD-L1 levels during treatment may be more accurate than a static baseline tumor biopsy; however, rebiopsying the primary or metastatic disease is rarely feasible.

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Small Cell Lung Cancer (SCLC) provide recommended management for patients with SCLC, including diagnosis, primary treatment, surveillance for relapse, and subsequent treatment. This selection for the journal focuses on metastatic (known as extensive-stage) SCLC, which is more common than limited-stage SCLC. Systemic therapy alone can palliate symptoms and prolong survival in most patients with extensive-stage disease.
