Recurrence as a small cell lung cancer transformation in a resected stage IIIA EGFR-mutated non-small cell lung cancer treated with adjuvant osimertinib: a case report.
Article in Translational lung cancer research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Based on improvements in recurrence-free and overall survival, osimertinib is now widely used as an adjuvant treatment in stage II-IIIA non-small cell lung cancer (NSCLC) presenting with a common epithelial growth factor receptor (EGFR) mutation. Histological transformation is a well-known resistance mechanism to osimertinib in EGFR-mutated metastatic NSCLC, but we currently have insufficient data on recurrence mechanisms in the adjuvant context. We present here the case of a patient treated with adjuvant osimertinib and presenting a small cell lung cancer (SCLC) transformation as a recurrence. Case Description: A 54-year-old man, never-smoker and with no previous medical history, underwent right superior lobectomy with lymph node resection for a pT3N1M0 [stage IIIA, tumor-node-metastasis (TNM) 8 Conclusions: this case report provides evidence of SCLC transformation while on adjuvant osimertinib, in a pT3N1 EGFR, RB1 and TP53-mutated pulmonary adenocarcinoma. This highlights the importance of biopsy on recurrence and the transformation potential of the EGFR, RB1 and TP53-mutated adenocarcinomas.
