The proportion of CD8+ cells was significantly higher in LNs from adenocarcinoma patients without metastases when compared to LNs from adenocarcinoma patients with metastases (median value (p25–p75): B = 80% (60–80) versus A = 52.5% (50–60), p < 0.05); see Table 2. This evidence concerns the gene CD8A and adenocarcinoma.
