Twenty-six patients were enrolled, all of whom were diagnosed with adenocarcinoma with EGFR mutations (19del: 16, L858R: 10) except one (squamous cell carcinoma with 19del).

Plasma DNA samples from 73 patients with stage IIIB to IV adenocarcinoma were analyzed for EGFR mutations in exons 19 (deletion mutation) and 21 (L858R mutation) using direct DNA sequencing, DHPLC and Scorpions ARMS.

Pulmonary adenocarcinoma tissue from 20 previously genotyped specimens was prepared for immunohistochemical staining by two antibodies that recognise products of in-frame deletions in exon 19 (E746_A750del) and a point mutation that replaces leucine with arginine at codon 858 in exon 21 (L858R) of the EGFR gene.

In this prospective study, EGFR exon 19 deletion or L858R mutations in adenocarcinoma were the best predictors for longer TTF in stage IIIB/IV chemotherapy-naive NSCLC patients receiving first-line gefitinib monotherapy.

In particular, 3 of 4 adenocarcinomas with EGFR mutations (all L858R point mutations in women, never or former smokers) had a concomitant and identical mutation in AAH, and 2 of 4 adenocarcinomas with K-ras mutations (both at codon 12 in women, a never and a current smoker) showed the same mutation in concomitant AAH.All cases were wild-type for HER2.

Herein, we report a case of 2 synchronous lung adenocarcinomas composed of 2 distinct pathological subtypes with different EGFR mutations: homozygous deletion in exon 19 in the papillary subtype of adenocarcinoma and a point mutation of L858R in exon 21 in the tubular adenocarcinoma.

Two weeks after induction with doxycycline, mice that express the EGFR(L858R) allele show diffuse lung cancer highly reminiscent of human bronchioloalveolar carcinoma and later develop interspersed multifocal adenocarcinomas.

The L858R mutation was significantly correlated with gender (women versus men, P < 0.0001), Brinkman index (600 < or = versus 600, P = 0.001), pathologic subtypes (adenocarcinoma versus nonadenocarcinoma, P = 0.007), and differentiation status of the lung cancers (well versus moderately or poorly, P = 0.0439), whereas the deletion mutants were not.
