All EGFR mutations are (not) created equal: focus on uncommon EGFR mutations.
Article in Journal of cancer research and clinical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
purposeMost common EGFR mutations in NSCLC include del19 and exon 21 L858R. Approximately 10% of patients have uncommon EGFR mutations (indels, missense mutations involving G719, L861 and S768 codons, and exon 20 insertions) that do not respond to TKIs.
methodsOf 490 EGFR mutated NSCLC samples, 60 cases harboring uncommon/compound EGFR mutations were reviewed retrospectively, and 44 were included for survival analysis.
resultsSixty (12.2%) patients with a median age of 63 years (25-84 years) had uncommon/compound EGFR mutations. Majority had no history of smoking (52; 86.7%). Most common major uncommon mutations (G719X in exon 18, L861Q in exon 21 and S768I in exon 20) were identified in 19 (31.7%) patients. 17 (28.3%) cases demonstrated exon 20 insertions. De novo T790M was observed in 7 (11.7%) cases and 9 cases exhibited compound/dual mutations. Among the 12 patients who received first-line EGFR TKI, 7 received afatinib. Median progression-free survival of patients following first-line afatinib was 8.13 months, irrespective of mutation type exhibited. Overall response rate to first-line afatinib therapy was 57.1%.
conclusionThe current study highlighted that rare/dual EGFR mutations are heterogeneous with distinct clinical features in a large Indian cohort of EGFR mutated patients with NSCLC.
