Osimertinib as Second- and ≥Third-Line Treatment in Advanced and Recurrence EGFR-Mutant NSCLC Patients Harboring Acquired T790M Mutation.
Article in Cancers, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
BACKGROUND/
objectivesOsimertinib is a standard sequential therapy for advanced and recurrent Epidermal Growth Factor Receptor (EGFR)-mutant non-small-cell lung cancer (NSCLC) patients with the T790M mutation, following treatment with first- or second-generation EGFR Tyrosine Kinase Inhibitors (TKIs). This study aims to investigate the differences in clinical outcomes between osimertinib as a 2nd-line treatment and as a ≥3rd-line treatment in this patient population.
methodsBetween September 2014 and March 2023, we enrolled advanced and recurrent T790M + NSCLC patients who had received osimertinib as sequential treatment for analysis. All patients had previously been treated with gefitinib, erlotinib, or afatinib as first-line therapy.
resultsA total of 158 patients who received osimertinib as sequential treatment were included in the final analysis. Of these, 99 patients (62.7%) received osimertinib as a 2nd-line treatment, while 59 patients (37.3%) were treated with osimertinib as ≥3rd-line therapy. The median progression-free survival (PFS) was 10.7 months for the 2nd-line group and 8.9 months for the ≥3rd-line group. The median overall survival (OS) from first-line treatment was 73.2 months in the 2nd-line group and 57.5 months in the ≥3rd-line group. No statistically significant differences in PFS or OS were observed between the two groups.
conclusionsOur research demonstrated that osimertinib is effective not only as a 2nd-line therapy but also as a ≥3rd-line treatment, offering promising clinical benefits for advanced and recurrent EGFR-mutant NSCLC patients with acquired T790M mutations who have developed resistance to first- and second-generation EGFR-TKI therapy.
