Welcome Letter

Welcome to the 2023 Annual Report! 2023 was a year of growth for IASLC. We crossed a historic milestone as our membership surpassed the 10,000 mark, and more than 7,800 delegates met both in person and online at our various events this year. Our growth has led us to expand our committee structure, allowing us to put more resources into focusing on topics vital to our membership and their mission to diagnose, treat, and find a cure for thoracic cancers.

Alex Adjei

“JTO’s impact factor has more than quadrupled from 5.040 in 2015 to 20.4 in 2022. This is a notable achievement since we are a sub-specialty journal dealing with only thoracic oncology. There are no other sub-specialty journals among the top 20 oncology journals. More importantly, the impact factor of other journals in thoracic oncology or surgery fell in 2022. This achievement is a testament to the exemplary work of our editorial board and our managing editor, as well as the support of IASLC—its executives, office staff, membership, and above all, our reviewers, readers, and authors. JTO will continue its emphasis on multidisciplinary research to serve the broad community working in thoracic oncology.”

IASLC Foundation

Despite advances in research and early detection that are creating better outcomes and hope for lung cancer patients and their families, lung cancer claims more lives each year than breast, colon, and prostate cancers combined. Yet lung cancer receives disproportionately less government research funding per cancer death than other types of cancer. This makes the need for private support of lung cancer research critical.

In 2023, the IASLC Foundation awarded nine research grants totaling $750,000. This year’s grant recipients represent another diverse group of researchers from around the world. IASLC Foundation Research Grants are made possible by donations from individual donors, foundation partners and pharmaceutical companies and foundations.
