abstract = {Patients with non-small cell lung cancer (NSCLC) harboring
activating mutations in the Epidermal Growth Factor Receptor
(EGFR) benefit from targeted therapies. A synonymous
polymorphism (rs1050171, p.Q787Q) was shown to be associated
with improved overall survival (OS) in colorectal cancer
patients. As data in NSCLC are limited, we retrospectively
analyzed associations of p.Q787Q with clinicopathological
parameters including clinical response and outcome in
patients with lung adenocarcinoma (ADC) who received
tyrosine kinase inhibitor (TKI) therapy. Of 642 ADC patients
whose tumors were profiled by next generation sequencing,
102 $(15.9\%)$ carried EGFR mutations targetable by TKIs
$(30.4\%$ male patients, median age 65.1 y, $19.6\%$ smokers
with 12.8 median pack years). Seventy-nine patients
$(77.5\%)$ received TKI therapy either as a first- or
second-line therapy. Of the 102 EGFR-mutant tumors, 72
$(70.6\%)$ exhibited the p.Q787Q polymorphism and another 12
$(11.8\%)$ cases with p.Q787Q harbored an additional TKI
insensitive mutation (p.T790M). The polymorphism was neither
associated with classic clinicopathological parameters nor
with overall survival (21.1 months vs. 20.1 months;
P-value = 0.91) or clinical response
(P-value = 0.122). The patients with p.T790M had worse
survival compared to EGFR activating mutation carriers with
and without p.Q787Q when analyzed as a separate group (27.5
months, P-value = 0.02). In conclusion, p.Q787Q is
neither a suitable prognostic nor predictive biomarker for
ADC patients receiving anti-EGFR therapy in first- or
second-line of therapy. © 2016 Wiley Periodicals, Inc.},
