JBR.10 JBR.10 -- ObjectivesObjectives
• Prospective, randomized controlled trial designed to determine whether adjuvant vinorelbine and cisplatin is superior to observation alone, in terms of overall survival, in patients who have undergone complete resection of early stage (IB and II) Non Small Cell Lung Cancer
• Secondary Endpoints– Recurrence free survival– Evaluate Toxicity of the Regimen– Health related Quality of Life Analysis– Explore the prognostic significance of ras mutations

JBR.10 JBR.10 -- ConclusionsConclusions• Vinorelbine and Cisplatin can be administered
safely post resection of NSCLC
• Impact on QoL was limited and generally reversiblewith the exception of neurotoxicity
• Adjuvant treatment with this 3rd generation chemotherapy combination significantly improves disease free and overall survival as compared to observation alone post complete resection of Stage IB and Stage II Non Small Cell Lung Cancer
