Table 1 Relationship between local invasion and gene mutation status

From: Relationship between EGFR gene mutation and local metastasis of resectable lung adenocarcinoma

Metastasis Mutated N = 64 Wild-type N = 39 P value (mutated vs. wild-type)
Exon 18 N = 2 exon 19 N = 36 exon 21 N = 26
Pleural invasion 1 22 20 17 p = 0.018
Lymph node metastasis 0 12 10 10 p > 0.05
Endobronchial metastasis 1 16 8 7 p = 0.005
