Promising signals across observational studies. Looking forward to seeing how the prospective data evolves.

So proud of @SamaddarMD for spearheading this interesting project- compiling data from various sources and making complex comprehensive analyses to identify environmental risk factors for lung cancer coupled with an outstanding poster presentation (the prettiest in my opinion)

⭐️ABSTRACT 8010: Air Pollution and Risk of Lung Cancer 📔The seminal 2023 @Nature paper showed a significant association in environmental particulate matter measuring ≤2.5 μm (PM2.5) and risk for #EGFR #NSCLC. 1⃣This large NCDB analysis (>1 million pts) suggests chronic PM₂.₅ exposure is associated with more advanced lung cancer findings 2⃣Key findings: - Each standard deviation increase in PM₂.₅ → ~5% higher odds of stage III/IV disease -In multipollutant models, PM₂.₅ remained significant (OR = 1.062, 95% CI: 1.047–1.076; p , 0.001), with combined pollution burden linked to a 3.1% increase in odds (95% CI: 1.5–4.7%; p , 0.001). 3⃣Caveats: -The study cannot distinguish if air pollution accelerates tumor progression (plausible) OR if air pollution here is linked with other determinants of care (smoking prevalence, occupational exposure, health care access) -No smoking pack year data? I understand the problems and recall biases associated with getting smoking level data, but seems like it would be important. -Ecologic exposure fallacy (county-level pollution ≠ individual exposure or risk) 📋KEY POINT: Emerging and ongoing population level data suggests link between air pollution and lung cancer risk. 😡RANT: We need more investment into these type of studies, to truly parse out these signals. This can only happen with funding. Sadly we are lacking vision, competence, and expertise from our elected officials and from our health care administration.

Fascinating oral ASCO abstract asking a key question: how do environmental and lifestyle factors contribute to carcinogenesis? Interesting work exploring whether physiologic burden may be one pathway to early-onset cancers. asco.org/abstracts-presentat… #ASCO2026 @ravi_b_parikh

What environmental factors may contribute to lung cancer risk beyond smoking? Looking forward to presenting our #ASCO26 poster on ambient carbon tetrachloride exposure and lung cancer incidence in the U.S. Abstract: asco.org/abstracts-presentat… @NagashreeSeeth1 @NorthwellHealth

The Gut Onc Lab happy hour at #GI26! Cheers to a great year of great science and collaborations. To many more 🥂 @deevyaparekh @GIMedOnc @TimothyJBrownMD @Deebacca @BRoseMDMPH @pjdisano
