7%, 32.1%, and 3.2% for GG, GA, and AA, respectively. During the follow-up, the FGB -455 A + genotype did not associate with survival, nor was there any genotype-by-smoking interaction on poor outcome in the total study population. However, women aged 55-71 years who carried the FGB -455 A-allele showed worse survival regardless of smoking status compared to non-smoking FGB -455 GG homozygotes (non-smokers,
crude HR = 5.21, 95% CI: 1.38-19.7; smokers, crude HR = 7.03, 95% CI: 1.81-27.3). This association persisted in adjusted analyses. No such association was observed for women GS-7977 molecular weight in the oldest age-group, nor among men. Conclusion: The A + genotype of the FGB -455 G/A polymorphism associated with poor survival among 55-71 years old Caucasian women
in the Finnish stroke cohort.”
“Objective: Molecular diagnostics capable of prognosticating disease recurrence in stage I non-small cell lung cancer (NSCLC) patients have implications for improving survival. The objective of the present study was to develop a multianalyte serum algorithm predictive of disease recurrence in stage I NSCLC patients.\n\nMethods: The Luminex immunobead platform was used to evaluate 43 biomarkers against 79 patients with resectable NSCLC, with the following cohorts represented: stage I (T-1-T2N0M0) NSCLC without recurrence (n = 37), stage I (T-1-T2N0M0) NSCLC with recurrence Apoptosis Compound Library high throughput (n = 15), and node-positive (T-1-T2N1-N2M0) NSCLC (n = 27). Peripheral blood was collected before surgery, with all patients undergoing anatomic resection. Univariate statistical methods (receiver
operating characteristics curves and log-rank test) were used to evaluate each biomarker with respect to recurrence and outcome. Multivariate statistical methods were used to develop a prognostic classification panel for disease recurrence.\n\nResults: No relationship was found between recurrence and age, gender, smoking history, or histologic type. Analysis for all SB273005 stage I patients revealed 28 biomarkers significant for recurrence. Of these, the log-rank test identified 10 biomarkers that were strongly (P < .01) prognostic for recurrence. The Random Forest algorithm created a 6-analyte panel for preoperative classification that accurately predicted recurrence in 77% of stage I patients tested, with a sensitivity of 74% and specificity of 79%.\n\nConclusions: We report the development of a serum biomarker algorithm capable of preoperatively predicting disease recurrence in stage I NSCLC patients. Refinement of this panel might stratify patients for adjuvant therapy or aggressive recurrence monitoring to improve survival. (J Thorac Cardiovasc Surg 2012; 144:1344-51)”
