Article Synopsis
  • Translating findings from lung cancer screening trials to real-world settings has been difficult, prompting the development of the Engaged Approach to Lung Cancer Screening (EA-LCS) framework to improve adherence and health outcomes.
  • The study used community-engaged research that involved interviews and surveys with LCS program staff and participants to identify effective strategies and principles that support adherence in lung cancer screening.
  • Key factors for improving adherence included personalized communication, reliable contact points, and organized operations, all centered around themes of respect, trust, and engagement, forming the basis for the EA-LCS framework.

Background: Patients with small cell lung cancer (SCLC) often respond to first-line chemoimmunotherapy. However, relapse is inevitable and is associated with a poor prognosis. Treatments for relapsed SCLC, such as lurbinectedin and topotecan, are limited by modest efficacy and significant hematologic adverse events, leaving a need for newer therapeutic agents or regimens.

Cachexia is a common complication of cancer and is associated with poor quality of life and a decrease in survival. Many patients with cancer cachexia suffer from inflammation associated with elevated cytokines, such as interleukin-1beta (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor (TNF). Single-agent trials to treat cancer cachexia have not led to substantial benefit as the type of cytokine which is elevated has rarely been specified and targeted.

Purpose: Platinum-based chemotherapy with or without immunotherapy is the mainstay of treatment for advanced stage non-small cell lung cancer (NSCLC) lacking a molecular driver alteration. Pre-clinical studies have reported that pharmacological ascorbate (P-AscH-) enhances NSCLC response to platinum-based therapy. We conducted a phase II clinical trial combining P-AscH- with carboplatin-paclitaxel chemotherapy.

Introduction: With the increased use of immune checkpoint inhibitors (ICI), it is essential to improve our understanding of immune-related adverse events (irAE). To date, most studies describing irAE have been performed in clinical trial populations, which may not be an accurate description of irAE in real-world populations. Also, identification of patients at increased risk of irAE is needed as early recognition may improve irAE outcomes.

Background: Informal family caregivers constitute an important and increasingly demanding role in the cancer healthcare system. This is especially true for caregivers of patients with primary malignant brain tumors based on the rapid progression of disease, including physical and cognitive debilitation. Informal social network resources such as friends and family can provide social support to caregivers, which lowers caregiver burden and improves overall quality of life.

After a diagnosis of cancer (or other serious disease), patients may be asked to consider joining a clinical trial. Because most people are unfamiliar with the scientific concepts that are necessary to the provision of meaningful informed consent, patient education is necessary. Increasing knowledge alone is not sufficient; understanding how clinical trial participation aligns with personal circumstances and knowledge is central to the decision-making process.

Cancer patients learn about research studies outside of the clinical environment, including websites, print and online advertisements, and interpersonal interactions. When cancer patients share credible information about clinical trials, they also frequently help clarify misunderstandings that may exist in their social networks. The present study investigated how an interactive tailored information aid on clinical trial participation motivated patients' information sharing behaviors.

Recent data and policy decisions have led to the availability of lung cancer screening (LCS) for individuals who are at increased risk of developing lung cancer. In establishing implementation policies, the US Preventive Services Task Force recommended and the Centers for Medicare and Medicaid Services required that individuals who meet eligibility criteria for LCS receive a patient counseling and shared decision-making consultation prior to LCS. This study evaluated the potential of a values clarification/preference elicitation exercise and brief educational intervention to reduce decisional conflict regarding LCS.
