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)
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)
At present, the only recognised prognostic factor for primary osteosarcoma is the histological response to preoperative chemotherapy.

A total of 54 patients under 20 years of age with primary osteosarcomas were studied while under treatment by the French(More)
