Combination TS-1 plus EGFR-tyrosine kinase inhibitors (TKIs) for the treatment of non-small cell lung cancer after progression on first-line or further EGFR-TKIs: A phase II, single-arm trial.
Trial report in Thoracic cancer, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundEGFR-tyrosine kinase inhibitors (TKIs) combined with TS-1 might overcome EGFR-TKI resistance, which has been indicated by several preclinical studies. We investigated the synergistic efficacy and safety of the combination therapy of EGFR-TKIs and TS-1 in non-small cell lung cancer (NSCLC) patients with acquired resistance to previous EGFR-TKI therapy.
methodsThis was a phase II, single-arm and single-center prospective study. Stage IIIB-IV NSCLC patients with acquired resistance to prior EGFR-TKI treatment were enrolled. All patients were administered combination therapy of TS-1 and continuing EGFR-TKIs in this study. The primary endpoints were progression-free survival (PFS), while overall survival (OS), disease control rate (DCR), and safety were secondary endpoints.
resultsA total of 42 patients with acquired resistance to EGFR-TKIs were eligible for this study. The median PFS for all patients was five months (95% confidence interval [CI] 3.6-5.4). The OS and DCR were 31.9 (95% CI 17.8-46.0) months and 69.0% (29/42), respectively. No grade 4 toxicity or grade 3 hematologic toxicity was observed in this study. One patient (2%) experienced grade 3 elevated total serum bilirubin.
conclusionThe combination treatment of TS-1 and EGFR-TKIs was effective and well tolerated by patients who had experienced prior EGFR-TKI treatment failure. Our results need to be validated by larger prospective clinical trials.
