Efficacy and safety of bevacizumab combined with chemotherapy in symptomatic brain metastases from lung adenocarcinoma: a retrospective analysis.
Article in Journal of thoracic disease, 2019. 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
backgroundCurrently, the treatment of symptomatic brain metastases from lung adenocarcinoma has remained difficult. Bevacizumab combined with chemotherapy is one of the standard treatments of lung adenocarcinoma. This study was designed to investigate the efficacy and safety of bevacizumab combined with chemotherapy in symptomatic brain metastases from lung adenocarcinoma that are not suitable for local treatments, and to explore the predictive value of baseline serum vascular endothelial growth factor (VEGF) for the treatment.
methodsWe retrospectively reviewed 14 consecutive patients, between Jan 2015 and Jul 2017, with brain metastases from lung adenocarcinoma who received bevacizumab and chemotherapy to determine efficacy and toxicity. Kaplan-Meier method was used to estimate survival curves, and univariate and multivariate analyses were performed by Cox proportional hazard model. The primary endpoints were objective response rate (ORR) and intracranial ORR (iORR). The secondary endpoints were progression-free survival (PFS), intracranial PFS (iPFS), overall survival (OS) and disease control rate (DCR).
resultsThe efficacy of 12 patient was evaluated. Overall ORR was 25% (3/12) and the iORR of brain lesions was 33.3% (4/12). DCR was 75% (9/12). The median OS was 18.3 months, the median PFS was 6.7 months, and the median iPFS was 12 months. After 2 cycles of bevacizumab, 10 patients showed improved symptoms of central nervous system (CNS), and the symptom control rate was 83.3% (10/12). Head MRI showed that edema in the brain was greatly reduced in 6 patients, resulting in the lessened usage of dexamethasone. iPFS was significantly shorter in high VEGF group (3.6
conclusionsThis study showed bevacizumab combined with chemotherapy could effectively control intracranial lesions, relieve symptoms, and improve the quality of life and survival of patients with brain metastases from lung adenocarcinoma. Serum baseline VEGF may be a predictor of efficacy of bevacizumab plus chemotherapy in the treatment of brain metastases from lung adenocarcinoma.
