Journal of thoracic oncology : official publication of the International Association for the Study of Lung Cancer

The seventh edition of the tumor, node, metastasis Classification of Malignant Tumors is due to be published in 2009. The recommendations of International Association for the Study of Lung Cancer for changes to the T descriptors have been published. We combined this new parameter with other well-established prognostic factors and performed multivariate survival analyses to validate its value in Chinese stage I non-small cell lung cancer (NSCLC). ⋯ The tumor size is a significant independent prognostic factors in stage I NSCLC.

The majority of patients with non-small cell lung cancer (NSCLC) develop distant metastases. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors are capable of reducing brain and adrenal metastases. However, the EGFR status may be discordant between primary NSCLC and the corresponding metastases. ⋯ Because the molecular asset of EGFR may change during the metastatic progression of NSCLC to brain (but not to adrenal), the selection of patients with brain metastasis for specific targeted therapies by EGFR FISH analysis should be performed on metastatic lesions rather than on their corresponding primary tumors.
