Abstract |
The issue of overdiagnosis in low-dose computed tomography (LDCT)-screening trials could be addressed by the development of complementary biomarkers able to improve detection of aggressive disease. The mutation profile of LDCT screening-detected lung tumours is currently unknown. Targeted next-generation sequencing was performed in 94 LDCT screening-detected lung tumours. Associations with clinicopathologic features, survival and the risk profile of a plasma microRNA signature classifier (MSC) were analyzed. Mutational spectrum and frequency observed in screening-series was similar to that reported in public datasets although a larger number of tumours without mutations in driver genes was detected. The 5-year overall survival (OS) of patients with and without mutations in the tumours was 66% and 100%, respectively (P=0.015). By combining the mutational status with the MSC risk profile, patients were stratified into 3 groups with 5-year OS ranging from 42% to 97% (P<0.0001) and the prognostic value was significant after controlling for stage (P=0.02). Tumour mutational status along with a miRNA-based liquid biopsy can provide additional information in planning clinical follow-up in lung cancer LDCT-screening programs. |
