Abstract 317P
Background
The biomarker testing to detect driver-mutations has been essential for selecting adequate treatment in non-small cell lung cancer (NSCLC). However, there are a certain number of patients with advanced or recurrent NSCLC in whom driver genes have not been sufficiently searched for before initial treatment. The purpose of this study was to investigate the actual status of biomarker testing and drug therapy, and to identify the problems in lung cancer treatment in the real-world setting.
Methods
This retrospective, multicenter study registered patients with advanced or recurrent NSCLC diagnosed between July 1, 2020 and June 30, 2021, in Japan. The primary endpoint was the actual status of biomarker testing. Treatment-related factors were also examined.
Results
1,500 pts were enrolled from 29 institutions. The multiplex gene testing was performed in 705/1,478 pts (48%), and OncomineDxTT was performed in 474/1,478 pts (32%). The implementation rate of biomarker testing was EGFR 84%, ALK 79%, ROS1 73%, BRAF 54%, MET 54%, and PD-L1 82%. The frequency of each driver mutation, EGFR, ALK, ROS1, BRAF, and MET were 25.6%, 3.9%, 2.3%, 1.7%, and 3.1%, respectively.
Conclusions
The implementation rate of multiplex gene testing was 48%. The positivity for each biomarker mutation was similar to that previously reported. We are currently collecting information on treatment and prognosis, and the rate of induction of systemic therapy and the proportion of patients receiving each targeted therapy drug based on each biomarker will be reported at this meeting. We hope that the results of this study would contribute to the establishment of a system where all patients with lung cancer can receive appropriate personalized medicine.
