Article Synopsis
  • This study investigates the effects of continuing osimertinib alongside platinum-pemetrexed chemotherapy for patients with EGFR mutant non-small cell lung cancer (NSCLC) who have had disease progression on osimertinib.
  • It analyzed data from 159 eligible patients out of 421 identified, comparing outcomes between two groups: one continuing osimertinib with chemotherapy and the other receiving chemotherapy alone.
  • Results showed that the group continuing osimertinib experienced a significant improvement in progression-free survival (9.0 months vs. 4.5 months), indicating a potential clinical benefit in this treatment strategy.

Article Synopsis
  • SARS-CoV-2 can spread from asymptomatic individuals, posing a greater risk to cancer patients who frequently visit healthcare facilities and are more vulnerable to severe COVID-19 outcomes.* -
  • A study of lung cancer patients revealed that over half of those with evidence of SARS-CoV-2 infection were asymptomatic at diagnosis, and a significant number were never clinically diagnosed.* -
  • The findings indicate that older patients and those with early-stage lung cancer are more likely to have asymptomatic infections, highlighting the need for continued preventive measures in high-risk populations.*

Lung cancer, the leading cause of cancer-related deaths globally, remains a pressing health issue despite significant medical advances. The New York Lung Cancer Foundation brought together experts from academia, the pharmaceutical and biotech industries as well as organizational leaders and patient advocates, to thoroughly examine the current state of lung cancer diagnosis, treatment, and research. The goal was to identify areas where our understanding is incomplete and to develop collaborative public health and scientific strategies to generate better patient outcomes, as highlighted in our "Calls to Action.

Article Synopsis
  • The RESILIENT trial compared the effectiveness of liposomal irinotecan and topotecan as second-line treatments for small cell lung cancer (SCLC) after initial chemotherapy.
  • No significant difference in overall survival (OS) was observed, with liposomal irinotecan showing a median OS of 7.9 months and topotecan at 8.3 months.
  • Liposomal irinotecan had a higher objective response rate (ORR) of 44.1% compared to 21.6% for topotecan, but both treatments had similar safety profiles with grade ≥3 adverse events.

Introduction: Acquired gene amplification, exon 14 skip mutations, or fusions can emerge as resistance mechanisms to tyrosine kinase inhibitors (TKIs) in patients with lung cancer. The efficacy and safety of combining MET TKIs (such as crizotinib, capmatinib, or tepotinib) with parent TKIs to target acquired MET resistance are not well characterized.

Methods: Multi-institutional retrospective chart review identified 83 patients with metastatic oncogene-driven NSCLC that were separated into the following two pairwise matched cohorts: (1) MET cohort (n = 41)-patients with acquired MET resistance continuing their parent TKI with a MET TKI added or (2) Chemotherapy cohort (n = 42)-patients without any actionable resistance continuing their parent TKI with a platinum-pemetrexed added.

Introduction: Pathologic response (PathR) by histopathologic assessment of resected specimens may be an early clinical end point associated with long-term outcomes with neoadjuvant therapy. Digital pathology may improve the efficiency and precision of PathR assessment. LCMC3 (NCT02927301) evaluated neoadjuvant atezolizumab in patients with resectable NSCLC and reported a 20% major PathR rate.

Patients diagnosed with lung cancer (LC) exhibit increased susceptibility to SARS-CoV-2 infection. Rodilla et al. monitor the levels of plasma anti-nucleocapsid antibodies within a cohort of fully vaccinated LC patients and reveal that the actual infection rate is nearly twice the documented rate, indicating a significant prevalence of unreported cases.

Introduction: Pathologic response has been proposed as an early clinical trial end point of survival after neoadjuvant treatment in clinical trials of NSCLC. The International Association for the Study of Lung Cancer (IASLC) published recommendations for pathologic evaluation of resected lung cancers after neoadjuvant therapy. The aim of this study was to assess pathologic response interobserver reproducibility using IASLC criteria.

Article Synopsis
  • - Bronchial squamous carcinoma in situ (CIS) is a precursor to invasive carcinoma, and a study from 1992 to 2016 examined its prevalence, molecular markers, and outcomes among affected individuals.
  • - Out of 31 CIS cases, 22 were found alongside invasive carcinomas, with some invasive tumors being undetectable through imaging; CIS can sometimes spread to other lung areas or transform into invasive cancer.
  • - Although isolated CIS can regress, it often accompanies invasive tumors, and genetic findings, such as TP53 mutations and chromosomal changes, may help understand the progression of these lesions in the airways.

Purpose: To compare the efficacy and toxicity of pemetrexed versus docetaxel in patients with advanced non-small-cell lung cancer (NSCLC) previously treated with chemotherapy.

Patients And Methods: Eligible patients had a performance status 0 to 2, previous treatment with one prior chemotherapy regimen for advanced NSCLC, and adequate organ function. Patients received pemetrexed 500 mg/m intravenously (IV) day 1 with vitamin B, folic acid, and dexamethasone or docetaxel 75 mg/m IV day 1 with dexamethasone every 21 days.

Article Synopsis
  • The study explores using tyrosine kinase inhibitors (TKIs) to treat patients with extensive brain metastases (BrM) from lung cancer, aiming to downstage their condition and avoid whole-brain radiotherapy.
  • Twelve patients with ALK, EGFR, and ROS1-driven non-small cell lung cancer (NSCLC) were treated with CNS-active TKIs, showing significant reductions in both the number and volume of BrMs.
  • Most patients experienced CNS progression after initial treatment, yet the overall survival rate from starting TKIs was promising, averaging 43.2 months.

Tyrosine kinase inhibitors (TKIs) targeting epidermal growth factor receptor (EGFR) are effective for many patients with lung cancer with EGFR mutations. However, not all patients are responsive to EGFR TKIs, including even those harboring EGFR-sensitizing mutations. In this study, we quantified the cells and cellular interaction features of the tumor microenvironment (TME) using routine H&E-stained biopsy sections.

Objective: Multimodality treatment for resectable non-small cell lung cancer has long remained at a therapeutic plateau. Immune checkpoint inhibitors are highly effective in advanced non-small cell lung cancer and promising preoperatively in small clinical trials for resectable non-small cell lung cancer. This large multicenter trial tested the safety and efficacy of neoadjuvant atezolizumab and surgery.

In an ongoing, open-label, single-arm phase II study ( NCT02927301 ), 181 patients with untreated, resectable, stage IB-IIIB non-small cell lung cancer received two doses of neoadjuvant atezolizumab monotherapy. The primary end point was major pathological response (MPR; ≤10% viable malignant cells) in resected tumors without EGFR or ALK alterations. Of the 143 patients in the primary end point analysis, the MPR was 20% (95% confidence interval, 14-28%).

Introduction: Survival benefit of immune checkpoint inhibitor (ICI) therapy in lung cancer is not fully understood.

Methods: PubMed-cataloged publications through February 14, 2022, were queried for randomized controlled trials of ICI in lung cancer, and identified publications were reviewed for inclusion. Reported Cox hazard ratios (HRs) for overall survival were transformed to Cox-TEL HR for ICI short-term survivors (ST-HR) and difference in proportions for patients with long-term survival (LT-DP).

Importance: Appropriate clinical decision-making relies on accurate data interpretation, which in turn relies on the use of suitable statistical models. Long tails and early crossover-2 features commonly observed in immune checkpoint inhibitor (ICI) survival curves-raise questions as to the suitability of Cox proportional hazards regression for ICI survival analysis. Cox proportional hazards-Taylor expansion adjustment for long-term survival data (Cox-TEL) adjustment may provide possible solutions in this setting.

The ADAURA adjuvant randomized trial demonstrated that osimertinib prolonged DFS. It has now been reported that health-related quality of life (HRQoL) was not adversely affected by adjuvant osimertinib. Does this mean that adjuvant osimertinib should now be standard as we await survival results? See related article by Majem et al.
