Abstract

Background and purpose EGFR TKIs alone have demonstrated activity against intracranial disease in EGFR mutant non-small cell lung cancer (NSCLC). This study aimed to determine if upfront cranial radiotherapy improves intracranial disease control and survival outcomes in EGFR mutant NSCLC with brain metastases relative to TKIs alone.Materials and methods We searched MEDLINE and various conference proceedings from 2008 to July 2014 for eligible studies where patients received upfront cranial radiotherapy or TKIs alone. Outcomes of interest were overall intracranial disease response rate (ORR), four-month intracranial disease progression-free survival (PFS), two-year overall survival (OS) and neurological adverse events (AE). We used random effects models to pool outcomes across studies and compared them using interaction tests.Results We found 12 non-comparative observational studies (n=363) with severe methodological limitations. Upfront cranial radiotherapy results in similar intracranial disease ORR (relative risk (RR) 0.93, 95% confidence interval (CI) 0.82-1.06; interaction p value (p)=0.53), improved four-month intracranial disease PFS (RR 1.06, 95% CI 1.00-1.12; p=0.03), improved two-year OS (RR 1.33, 95% CI 1.00-1.77; p=0.05) but caused more neurological AEs than TKIs alone.Conclusion There is evidence, albeit of low quality, that upfront cranial radiotherapy may improve intracranial disease control and survival outcomes compared with TKI alone.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
