Abstract
Disclosed are a tumor biomarker and application thereof, and a tumor detection kit. Patients suffering from non-small cell lung cancer, containing an EML4-ALK or SLC34A2-ROS1 fusion gene, have a specific circular RNA in blood. The base sequences of the circular RNA are represented by SEQ ID NOS. 1-6. The circular RNA is associated with non-small cell lung cancer, stably and constantly exists in plasma samples, and has high specificity and effectiveness, and thus can be used as a biomarker for tumor detection. Reagents such as primers and probes for detecting the circular RNA can be used for preparing the tumor detection kit.
