BACKGROUND There is scarce data available about epidermal growth factor receptor (EGFR) mutations other than common exon 19 deletions and exon 21 (L858R) mutations. PATIENTS AND METHODS EGFR exon 18 and/or exon 20 mutations were collected from 10 117 non-small-cell lung cancer (NSCLC) samples analysed at 15 French National Cancer Institute(More)
The epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) erlotinib improves survival of lung cancer as second- or third-line therapy. However, after an initial response, most patients will recur, particularly within the central nervous system. The present study reports the case of a 27-yr-old nonsmoking male presenting with a metastatic(More)
INTRODUCTION Coexistence of pulmonary nodules in operable non small cell lung cancer (NSCLC) may influence the therapeutic indication. The aim of this study was to evaluate prospectively the prevalence and the probability of malignancy of pulmonary nodules in operable lung cancer. METHODS From a prospective database, all surgically treated patients(More)
Non-small cell lung cancers (NSCLC), in particular adenocarcinoma, are often mixed with normal cells. Therefore, low sensitivity of direct sequencing used for K-Ras mutation analysis could be inadequate in some cases. Our study focused on the possibility to increase the detection of K-Ras mutations in cases of low tumour cellularity. Besides direct(More)
Epidermal growth factor receptor (EGFR) is a cell membrane tyrosine kinase receptor. Activating mutations at exon 19 and 21 of the EGFR gene are associated with the occurrence and development of lung adenocarcinoma. These gain of function mutations predict responsiveness to EGFR tyrosine kinase inhibitors (TKis), erlotinib or gefitinib and are also a(More)
AIDS was the cause of the majority of deaths from HIV infection before 1996 but since the introduction of antiretroviral therapies the causes of mortality have changed considerably. In 2010, 75 % of deaths were due to diseases other than AIDS, the majority being cancers. Lung cancer is the most common in terms of both incidence and mortality. It shows(More)
In France, the number of tobacco-related deaths is estimated at 73,000 per year, including 44,000 from cancer and more than 20,000 from lung cancer (LC). Smoking cessation is the most effective measure to reduce the epidemic of LC, but it is also important in the management of patients with LC regardless on stage. In localized cancers, continuing to smoke(More)
INTRODUCTION Sonic Hedgehog (Shh) pathway is physiologically activated during embryogenesis and development. It plays a role in idiopathic lung fibrosis and is also activated in several solid cancers. STATE OF THE ART Shh pathway is reactivated in thoracic cancers, as small cell lung carcinoma, non-small cell lung carcinoma and malignant pleural(More)
MET is a cell membrane tyrosine kinase receptor for its ligand the hepatocyte growth factor (HGF), also called scatter factor (SF). MET conveys mitogenic, motogenic and proangiogenic signals, important during embryonic development and during the development of cancer. Activation of the HGF-MET pathway seems to be associated with a poor prognosis in lung(More)
Lung cancer (LC) is a major public health issue because of its frequency, but especially because of the severity of this disease. The epidemiology has changed with an increased incidence in non-smokers and women. The ATS/ERS/IASLC classification of adenocarcinomas was modified in 2011, and they are now the most frequent histological subtype. More than half(More)
