When to add anti-angiogenesis drugs to EGFR-mutated metastatic non-small cell lung cancer patients: a real-world study from Taiwan.
Article in BMC cancer, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
backgroundThe addition of anti-angiogenesis drugs to epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) or chemotherapy in patients with EGFR-mutant non-small cell lung cancer (NSCLC) can improve disease control. We conducted a study to evaluate the efficacy of combination therapeutic strategies and identify patients who could benefit from combination therapy.
methodsThis study enrolled patients with stage IV EGFR-mutant NSCLC treated with first-line EGFR-TKIs between January 2014 and December 2020. We divided patients into three groups: patients who received an anti-angiogenesis drug as first-line combination therapy, those who received an anti-angiogenesis drug as further-line combination therapy, and those with no anti-angiogenesis therapy.
resultsA total of 204 patients were enrolled in the final analysis. Progression-free survival (PFS) in patients receiving first-line anti-angiogenesis plus EGFR-TKI combination therapy was longer (18.2 months) than those treated with first-line EGFR-TKI monotherapy (10.0 months for both, p < 0.001). No difference in overall survival (OS) was observed among these three groups (30.5 vs. 42.6 vs. 33.7 months, p = 0.326). Multivariate Cox regression analysis revealed L858R mutation, pleural, liver, and bone metastasis as independent prognostic factors for poor OS. However, the addition of anti-angiogenesis therapy to patients with these poor prognostic factors improved OS to levels similar to those without these poor prognostic factors.
conclusionFirst-line combination EGFR-TKI plus anti-angiogenesis therapy improves PFS in patients with stage IV EGFR-mutant NSCLC. Adding an anti-angiogenesis drug at any line to patients harboring L858R mutation with pleural, liver, or bone metastases can provide survival benefits.
