| Gene polymorphisms of phase I (CYP1A1 and CYP2E of cytochrome P,) and phase II (GSTM1, GSTT1 and GSTP1 of glutathione-S-transferase,) enzymes and the TP53 tumor suppressor gene were studied as markers in a sample of 262 Brazilians of European descent, the sample consisting of 97 patients with non-small-cell lung cancer (NSCLC), 75 patients with chronic obstructive pulmonary disease (COPD) and 90 control individuals. For NSCLC, we found no significant relationship between any of the markers studied and susceptibility to this disease. With respect to COPD, although the distribution of the CYP1A1, GSTM1, GSTP1, GSTT1 and TP53 genotypes was similar to that of the controls the frequency of the CYP2E1*1A/*5B heterozygote was about 6 times higher in COPD patients... |

| Non-small-cell lung cancer (NSCLC) patients who experience brain metastases are usually associated with poor prognostic outcomes. This retrospective study proposed to assess whether bevacizumab or gefitinib can be used to improve the effectiveness of whole brain radiotherapy (WBRT) in managing patients with brain metastases. A total of 218 NSCLC patients with multiple brain metastases were retrospectively included in this study and were randomly allocated to bevacizumab-gefitinib-WBRT group (n=76), gefitinib-WBRT group (n=77) and WBRT group (n=75). Then, tumor responses were evaluated every 2 months based on Response Evaluation Criteria in Solid Tumors version 1.0. Karnofsky performance status and neurologic examination were documented every 6 months after... |
