NCIC-CTG BR.10 Trial
Patients’ tumor and normal lung tissue collected in a paraffin block and frozen tumor bank and analysed for presence or absence of ras gene mutation
Clinical question: Could vinorelbine and cisplatinum have adjuvant benefits for survival in stage IB and II NSCLC patients?
Molecular pathology question: Could we identify molecular markers in the tumor tissue of these patients that can predict improvement in survival with or without adjuvant chemotherapy?
7
NCIC-CTG BR.10 Trial
Early stage I and II NSCLC patients have an overall 5-year survival rate of 50%.
Phase II results suggested that in advanced NSCLC, vinorelbine plus cis-platinum yielded a 25-40% response rate.
A phase III prospective randomized study of adjuvant chemotherapy with
vinorelbine(长春瑞滨) and cisplatin(顺铂) in completely resected non-small cell lung cancer
