Pulmonologists' Attitudes and Role in Precision Medicine Biomarker Testing for Non-Small Cell Lung Cancer.
Article in Chest, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDespite advances in precision medicine for non-small cell lung cancer (NSCLC), biomarker testing for these therapies remains frequently underused, delayed, and inequitable. Pulmonologists often play a critical role in the initial diagnostic steps for patients with lung cancer, and previous data show variability in their knowledge and practices regarding biomarker testing. The purpose of this study is to better understand how pulmonologists view their role in lung cancer care. RESEARCH QUESTION: With the increasing importance of biomarker testing and precision medicine, how do pulmonologists view their role in lung cancer care? STUDY
designAn electronic survey consisting of 31 items focused on attitudes and practices regarding diagnostic steps for NSCLC was randomly distributed to a sample of practicing pulmonologists in the American College of Chest Physicians (CHEST) analytics database. Inferential statistics were performed using χ
resultsA total of 401 pulmonologists responded to the survey. Most (92%) were general pulmonologists, and more than one-half (62%) indicated they order biomarker testing. Longer practice tenure, higher case volumes, and participation in a multidisciplinary tumor board were associated with ordering biomarkers (P < .05). Pulmonology was identified to have the leading responsibility for the initial diagnostic biopsy by most respondents (83%) and less often for staging (45%), leading discussions about biomarker testing with patients (28%), and for ordering biomarkers (22%). The most common reasons for not ordering biomarkers included the following: oncology was responsible (84%), it was not within their scope of practice (46%), or lack of the necessary knowledge (51%).
interpretationThis study shows that pulmonologists vary in their practices for ordering biomarkers, and many defer this responsibility to oncology. Despite the role of bronchoscopy and pulmonology societal guidelines for staging, many defer leadership of this process. Many pulmonologists lack the necessary resources and multidisciplinary infrastructure likely required to efficiently accomplish biomarker testing.
