Racial and ethnic disparities in genomic testing among lung cancer patients: a systematic review.
Clare Meernik et al. J Natl Cancer Inst 2024 2
From the abstract: "We conducted a systemic review to examine racial and ethnic disparities in the use of genomic testing among lung cancer patients in the U.S. Two comprehensive searches in PubMed, Embase, and Scopus were conducted (September 2022, May 2023). Original studies that assessed rates of genomic testing by race or ethnicity were included. A majority of studies, though not all, observed racial and ethnic disparities in the use of genomic testing among patients with lung cancer. Heterogeneity of study results throughout a period of changing clinical guidelines suggests that minoritized populations—Black patients in particular—have faced additional barriers to genomic testing."
Concurrent Circulating Tumor DNA and Tissue Genotyping-Ready for Prime Time?
Benjamin A Bleiberg et al. JAMA Netw Open 2024 1 (1) e2351679
From the article: "Cell-free circulating tumor DNA (ctDNA) is shed by tumor cells into the systemic circulation and, thanks to advancements in next-generation sequencing (NGS) technologies, affords the opportunity to noninvasively detect cancer-specific somatic variants. The use of ctDNA-based molecular genotyping for tumor profiling and identification of patients eligible for targeted therapies has been integrated into clinical practice for a variety of tumor types. The prime example of this is in non–small cell lung cancer (NSCLC), where identifying actionable variants via genomic profiling is essential to determining the appropriate standard of care for patients.

Lung cancer in patients who have never smoked - an emerging disease.
Jaclyn LoPiccolo et al. Nat Rev Clin Oncol 2024 1
From the abstract: " New data have provided important insights into the molecular and genomic characteristics of LCINS, which are distinct from those of smoking-associated lung cancers and directly affect treatment decisions and outcomes. Herein, we review the emerging data regarding the aetiology and features of LCINS, particularly the genetic and environmental underpinnings of this disease as well as their implications for treatment.

Perioperative Durvalumab for Resectable Non-Small-Cell Lung Cancer.
John V Heymach et al. N Engl J Med 2023 10 (18) 1672-1684
From the abstract: "Neoadjuvant or adjuvant immunotherapy can improve outcomes in patients with resectable non–small-cell lung cancer (NSCLC). Perioperative regimens may combine benefits of both to improve long-term outcome. 802 patients were randomly assigned to receive durvalumab (400 patients) or placebo (402 patients). Perioperative durvalumab plus neoadjuvant chemotherapy was associated with significantly greater event-free survival and pathological complete response than neoadjuvant chemotherapy alone, with a safety profile that was consistent with the individual agents.
