Figure 2. Relationship between TMPRSS2 expression and clinicopathological parameters of lung cancer patients. TMPRSS2 expression was assessed in (A) male and female LUAD (normal, n = 59; male, n = 238; female, n = 276) and LUSC (normal, n = 52; male, n = 366; female, n = 128) patients, (B) patients with different stages of LUAD (normal, n = 59; stage 1, n = 277; stage 2, n = 125, stage 3, n = 85; stage 4, n = 28) and LUSC (normal, n = 52; stage 1, n = 243; stage 2, n = 157, stage 3, n = 85; stage 4, n = 7), (C) patients with different nodal metastasis statuses of LUAD (normal, n = 59; N0, n = 331; N1, n = 96, N2, n = 74; N3, n = 2) and LUSC (normal, n = 52; N0, n = 320; N1, n = 131, N2, n = 40; N3, n = 5). *p < 0.05, **p < 0.01, ***p < 0.001.
