The aim of this study was to explore the feasibility and utility of implementation of EGFR molecular testing from pleural effusions in non-small cell lung cancer in the clinical diagnostics workflow.// Patients and methods: This study included patients diagnosed with primary lung adenocarcinoma in the period July 2016 to June 2023. EGFR mutation testing was performed by qPCR (Cobas®) and dPCR. Testing was performed from 211 plasma samples when tissue was unavailable at diagnosis, and from 301 plasma samples and 18 pleural effusions at progression on first/second generation of EGFR TKIs. Descriptive methods of statistical analysis were used to summarize the sample data. Fisher's exact test, McNemar's test, Cohen's kappa tests were used for statistical analyses. Two-sided p-values <0.05 were considered statistically significant.// Results: A significantly higher detection rate of the T790M mutation in pleural effusion was obtained compared to blood (50% and 20%, p=0.047). When comparing the detection success rate of the resistant T790M mutation in pleural effusion and blood, a statistically significant difference was obtained in favor of pleural effusion (50% vs. 21.87%, p=0.01).// Conclusions: Superior performance of pleural effusions compared to blood plasma was shown both in the analysis of success rate and in the detection of the resistant T790M mutation, at progression on EGFR TKIs. Pleural effusion should be considered in this setting whenever available, especially in countries with limited health resources. date: 2023-11 date_type: published publisher: ELSEVIER SCIENCE INC official_url: https://doi.org/10.1016/j.tranon.2023.101772 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2082542 doi: 10.1016/j.tranon.2023.101772 medium: Print-Electronic pii: S1936-5233(23)00158-4 lyricists_name: Tanic, Miljana lyricists_id: MTANI82 actors_name: Tanic, Miljana actors_id: MTANI82 actors_role: owner funding_acknowledgements: 451-03-47/2023-01/200043 [Ministry of Science, Technological Development and Innovation of the Republic of Serbia]; 6060876 [Science Fund of the Republic of Serbia] full_text_status: public publication: Translational Oncology volume: 37 article_number: 101772 pages: 8 event_location: United States issn: 1936-5233 citation: Vukovic, Miodrag; Tanic, Miljana; Damjanovic, Ana; Pavlovic, Marijana; Stanojevic, Aleksandra; Zivic, Katarina; Karadzic, Valentina; ...
