Changing the treatment method, including withdrawal from surgery, can help avoid unnecessary treatment, but on the other hand, may potentially reduce the patient's chances of survival by depriving them of the possibility of radical treatment.

Non-small cell lung cancer (NSCLC) accounts for more than 80% of lung cancer. CircRNA is a new type of non-coding RNA. CircRNA was found to be deeply involved in the regulation of NSCLC cells. However, the principle of CircRNA regulating NSCLC cells needs to be further explored. The relative mRNA expression levels of CircRNA_103993, miR-1271 and ERG were detected by quantificational real-time polymerase chain reaction (qRT-PCR) in NSCLC cells and human bronchial epithelial cell line HBE. Cell proliferation was detected by the Cell Counting Kit (CCK8) when NSCLC cells were transfected with si-CircRNA_103993, si-NC, miR-1271 mimics, miR-NC, LV-ERG, respectively. The apoptotic rate of NSCLC cells was measured by apoptotic assay and flow Cytometry. The relative mRNA and protein expression levels of PCNA and caspase-3 were detected by Western blot and qRT-PCR. CircRNA_103993 and ERG were significantly up-regulated while miR-1271 was significantly down-regulated in NSCLC cells. Knockdown of CircRNA_103993 andR-1271. The CircRNA_103993 /miR-1271/ ERG axis had an important effect on the proliferation and apoptosis of NSCLC cells. Therefore, CircRNA_103993 may be a target for treating lung cancer. CircRNA_103993 was highly expressed in NSCLC cells. CircRNA_103993 regulated proliferation and apoptosis o
