Furthermore, a high level of FOXD3-AS1 indicated a more advanced stage of LUAD (P=0.012) and LUSC (P=0.010), a greater probability of lymph metastasis in LUAD (P=0.025) and LUSC (P < 0.001), and a greater probability of distal metastasis in SCLC (P=0.032). This evidence concerns the gene FOXD3 and small cell lung carcinoma.
