This study aims to assess first, whether mutations in the epidermal
growth factor receptor (EGFR) and Kirsten rat sarcoma (kRAS) genes
are associated with overall survival (OS) in patients who present
with symptomatic bone metastases from non-small cell lung cancer
(NSCLC) and secondly, whether mutation status should be incorporated into
prognostic models that are used when deciding on the appropriate
palliative treatment for symptomatic bone metastases. We studied 139 patients with NSCLC treated between 2007 and 2014
for symptomatic bone metastases and whose mutation status was known.
The association between mutation status and overall survival was
analysed and the results applied to a recently published prognostic
model to determine whether including the mutation status would improve
its discriminatory power.Aims
