%X <B>UNASSIGNED: </B>To determine the appropriate treatment for patients with advanced/recurrent nonsquamous non‒small-cell lung cancer (NSCLC), a companion diagnostic was conducted to detect driver mutations through genetic testing. In Japan, Oncomine Dx Target Test (DxTT) using next-generation sequencing (NGS) that can comprehensively detect gene mutations or single-gene tests are conducted as companion diagnostics. Furthermore, cost-effectiveness analysis was conducted to compare the cost-effectiveness of Oncomine DxTT using NGS with that of single-gene test in Japan.<BR><B>UNASSIGNED: </B>The target population included patients with advanced/recurrent nonsquamous NSCLC. A model structure was constructed for the Oncomine DxTT strategy and three single-gene tests (i.e., epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK)/c-ros oncogene 1 (ROS1) rearrangements) with reference to previous studies and the Clinical Practice Guidelines of Lung Cancer 2022 in Japan. The model structure assumed that genetic testing would be conducted and first-line treatment used the drug most recommended in the 2022 Japanese Lung Cancer Clinical Practice Guidelines, depending on the driver mutation,. Model inputs were obtained from the literature and price list in Japan, and cost-utility analysis was conducted.<BR><B>UNASSIGNED: </B>For the Oncomine DxTT strategy, the expected incremental costs and effectiveness were estimated to be approximately JPY 172,361 (JPY 12,285,228 vs. JPY 12,112,867 for strategies A and B, respectively) and -0.51 quality-adjusted life-year (QALY) per patient (21.93 QALY vs. 22.44 QALY for strategies A and B). As a result, the costs increased but the effectiveness decreased. Therefore, the Oncomine DxTT strategy was dominated by the three single-gene tests. Sensitivity and scenario analyses revealed that the test success rate of Oncomine DxTT affected the results.<BR><B>UNASSIGNED: </B>The genetic test using Oncomine DxTT before the first-line treatment is not cost-effective compared with the three single-gene tests (EGFR/ALK/ROS1) for patients with advanced/recurrent nonsquamous NSCLC.
