Abstract

11044 Background: Social media has proven vital in the rapid dissemination of literature to medical professionals and the public. In recent years, seminal research articles have yielded breakthrough therapies for lung cancer, including targeted drugs and unique immunotherapy-based combinations. New metrics such as the Altmetric Attention score (AAS) and PlumX Impact score capture interactions through social media and other public forums and serve as swifter counterparts to citations, which can take years to accrue. In this study, we characterize and compare AAS, PlumX and traditional bibliometrics (citation count, impact factor [IF]) of the top 100 trending articles on lung cancer. Methods: The 100 articles with the highest AAS featuring the keywords “lung cancer” between 01/2019 and 12/2021 were identified via Altmetric explorer. AAS, open access status, article type, topic, year and continent of publication were collected. PlumX and citation count were identified via Scopus database. Analysis included Spearman correlation coefficients and ANOVA. Results: A majority of the 100 articles were original investigations, of which 40% were RCTs, 22% retrospective cohort, 14% prospective, 9% basic science, 8% cross-sectional and 6% genome-wide association studies. Most articles focused on NSCLC (59%) and were conducted in North America (44%); 13% were in Europe, 36% multi-continental and the remainder < 5% each. PlumX positively correlated with both citation count (p <.001, r =.765) and IF (p <.001, r =.581). AAS did not correlate with citation or IF. Articles on guidelines (p <.001) and screening (p <.001) were associated with higher AAS in comparison to other article types and topics, respectively. Basic science articles were associated with a higher PlumX (p <.001) in comparison to others article topics. Year and continent of publication did not impact PlumX or AAS. Open access status did not correlate with PlumX or AAS. Conclusions: In our study, PlumX scores strongly correlated with citations and IF for recently published articles on lung cancer; this mirrors trends in other specialties. PlumX may be predictive in terms of academic impact, making it valuable to the research community. Though AAS did not correlate with traditional bibliometrics, its association with guidelines and screening articles suggests AAS may reflect interactions amongst a broader community (oncologic and non-oncologic clinicians). With the growing use of social media, the continued exploration of alternative metrics will play a role in understanding readership and fields of interest in lung cancer and in anticipating academic impact.[Table: see text]
