Background/Aims: Mutations of the epidermal growth factor receptor (EGFR) and Kirsten rat
sarcoma viral oncogene (KRAS) are important in the pathogenesis of lung cancer, and …

Adenosquamous carcinoma (ADSQ) is uncommon in non-small cell lung cancer (NSCLC).
The frequency rate of ADSQ was 9.7% of 6990 primary lung cancers resected in our …

Purpose This study was designed to determine the relationship of cigarette smoking to the
frequency and qualitative differences among KRAS mutations in lung adenocarcinomas …

BACKGROUND. In western countries, the Kirsten ras oncogene homolog gene (KRAS)
mutation rate is high in patients with nonsmall cell lung cancer (NSCLC), especially in those …

Molecular genetic analysis of epidermal growth factor receptor (EGFR) and Kirsten rat
sarcoma viral oncogene (KRAS) mutations in lung adenocarcinoma has become an integral …

EGFR and KRAS mutation profile in non-small cell lung cancers (NSCLCs) shows wide
variations due to geographic and ethnic background. We aimed to determine the frequency …

Background The prognostic and predictive value of KRAS mutations in patients with lung
cancer is controversial. Biases in disease stage, treatment regimen, small-scale patient …

We examined the correlation between computed tomography (CT) findings and the
incidence of epidermal growth factor receptor (EGFR) and Kras mutations in lung …

The epidermal growth factor receptor (EGFR), and its family members play an important role
in the development and progression of lung cancers. It has been reported that somatic …

In primary lung adenocarcinoma, EGFR and KRAS mutations are found in approximately
10% to 20% and 20% to 30%, respectively. Few studies have investigated these mutations …
