Lidocaine treatment inhibited the cell migration of the lung cancer cells. A549 and H1299 cells were treated with 4 mM lidocaine, and cell migration was detected by wound healing and transwell assays. The wound healing (A) and transwell (B) assays were performed to determine the cell migration ability of the lung cancer cells after lidocaine treatment. **P < 0.01 vs. Control group.
