Signal transducer and activator of transcription？3 overexpression promotes lymph node micrometastasis in early‐stage non‐small cell lung cancer

Signal transducer and activator of transcription？3 (STAT3) is constitutively activated in several malignancies. Here, we define the correlation between STAT3 expression and lymph node micrometastasis of early‐stage non‐small cell lung cancer. Then we highlight some possibilities associated with developing a way to detect tumor micrometastasis and an anticancer drug that might therapeutically inhibit the STAT3 signaling pathway
