Real-world clinical and economic outcomes for patients with advanced non-small cell lung cancer enrolled in a clinical trial following comprehensive genomic profiling via liquid biopsy.

Background: Oncology clinical trial enrollment is strongly recommended for patients with cancer who are not eligible for established and approved therapies. Many trials are specific to biomarker-targeted therapies, which are typically managed as specialty pharmacy services. Comprehensive genomic profiling (CGP) of advanced cancers has been shown to detect biomarkers, guide targeted treatment, improve outcomes, and result in the clinical trial enrollment of patients, which is modeled to offset pharmacy costs experienced by US payers, yet payer policy coverage remains inconsistent.

Trametinib sensitizes KRAS-mutant lung adenocarcinoma tumors to PD-1/PD-L1 axis blockade via Id1 downregulation.

Background: The identification of novel therapeutic strategies to overcome resistance to the MEK inhibitor trametinib in mutant KRAS lung adenocarcinoma (LUAD) is a challenge. This study analyzes the effects of trametinib on Id1 protein, a key factor involved in the KRAS oncogenic pathway, and investigates the role of Id1 in the acquired resistance to trametinib as well as the synergistic anticancer effect of trametinib combined with immunotherapy in KRAS-mutant LUAD.

Methods: We evaluated the effects of trametinib on KRAS-mutant LUAD by Western blot, RNA-seq and different syngeneic mouse models.

Patients And Methods: NSCLC tumors (N = 16,896) were analyzed by next-generation sequencing (DNA-Seq/592 genes).

Effectiveness and safety of the bevacizumab and erlotinib combination erlotinib alone in EGFR mutant metastatic non-small-cell lung cancer: systematic review and meta-analysis.

Background: The EGFR gene encodes a protein that stimulates molecular pathways that allow the growth and development of the tumor microenvironment. The current preferred tyrosine kinase inhibitor (TKI) for the first-line treatment of EGFRm metastatic non-small cell lung cancer (NSCLC) is osimertinib. However, the combination of angiogenesis inhibitors and TKI has produced discordant results.

Molecular Targeting of the BRAF Proto-Oncogene/Mitogen-Activated Protein Kinase (MAPK) Pathway across Cancers.

The mitogen-activated protein kinase (MAPK) pathway is essential for cellular proliferation, growth, and survival. Constitutive activation of this pathway by BRAF mutations can cause downstream activation of kinases, leading to uncontrolled cellular growth and carcinogenesis. Therefore, inhibition of BRAF and the downstream substrate MEK has been shown to be effective in controlling tumor growth and proliferation.

Diversity and Disparities in Lung Cancer Outcomes Among Minorities.

Because of diversities and disparities, lung cancer incidence and mortality rates among minorities are disproportionate compared with non-Hispanic White (NHW) populations. This review focuses on the disparities in lung cancer screening, diagnosis, treatment, and outcomes that minorities, mainly Hispanic and Black, experience compared with NHW populations. Despite efforts such as improving the eligibility criteria for screening to improve lung cancer survival rates, disparities persist, particularly among minority populations.

Importance of gene fusions in non-small cell lung cancer.

Targeted therapy has become one of the standards of care for advanced lung cancer. More than 10 genetic aberrations have been discovered that are actionable and several tyrosine kinase inhibitors (TKIs) have been approved to target each of them. Among several genetic aberrations that are actionable in non-small cell lung cancer (NSCLC), translocations also known as gene fusion proteins, are found in only 1%-2% of the patient population.

Case report: Osimertinib administration during pregnancy in a woman with advanced EGFR-mutant non-small cell lung cancer.

Lung cancer (LC) is one of the most common causes of death worldwide. The identification of oncogene-addicted driving mutations suitable for targeted therapy has improved clinical outcomes in advanced diseases. Clinical trials, on the other hand, rarely involve vulnerable groups such as pregnant women.

Genomic Landscape of Primary Resistance to Osimertinib Among Hispanic Patients with EGFR-Mutant Non-Small Cell Lung Cancer (NSCLC): Results of an Observational Longitudinal Cohort Study.

Background: Epidermal growth factor receptor (EGFR) mutations (EGFRm) represent one of the most common genomic alterations identified among patients with non-small cell lung cancer (NSCLC). Several targeted agents for patients with EGFRm have been proven safe and effective, including the third-generation tyrosine kinase inhibitor (TKI) osimertinib. Nonetheless, some patients will present with or develop EGFR-TKI resistance mechanisms.

Crizotinib and entrectinib have been approved to treat fusion-positive (ROS1) non-small-cell lung cancer. However, unmet needs remain, including treatment of patients with resistance mutations, efficacy in brain metastasis and avoidance of neurological side effects. Taletrectinib was designed to: improve efficacy; overcome resistance to first-generation ROS1 inhibitors; and address brain metastasis while conferring fewer neurological adverse events.

Liquid Biopsy Versus Tissue Biopsy to Determine Front Line Therapy in Metastatic Non-Small Cell Lung Cancer (NSCLC).

In the last decade, non-small-cell lung cancer (NSCLC) treatment has improved with the approval of multiple therapies to target specific genetic alterations. Though, next generation sequencing (NGS) has traditionally been conducted from tissue biopsy samples, developing data supports the use of plasma-based circulating tumor DNA (ctDNA), also known as "liquid biopsy," to complement tissue biopsy approaches in guiding front-line therapy. This study is a retrospective analysis of 170 new NSCLC patients treated at 2 cancer centers within a 5-year period who received both tissue and liquid biopsy NGS as standard of care.
