摘要: Background: We hypothesize that among patients with lung cancers the KRAS / EGFR mutation profile and overall survival of collegiate smokers (former who smoked between 101 lifetime cigarettes 5 pack-years) are distinct from those never former 15 pack-years or more. Methods: collected age, sex, stage, survival, smoking history for evaluated 2004 to 2009 advanced stage known status. Mutation were compared using Fisher's exact test log-rank test, respectively. Results: Data available 852 advanced-stage status, which 6% smokers, 36% 30% The (15% mutations, 27% mutations) was ( p = 0.9). Median 25 months, 32 months 0.4), 33 0.48), 21 more 0.63). Conclusions: Collegiate represent a subgroup higher frequency mutations lower smokers. These observations reinforce recommendation routine testing all no degree tobacco exposure is safe.
