In addition, a statistically significant positive correlation (Spearman’s correlation test) was found between POSTN expression in cancer cells (Table S4)/in tumor stroma and VEGF-A expression across the entire group of patients with NSCLC (r = 0.36, p < 0.001; Figure 10A), as well as in the individual histological subtypes: AC (r = 0.36, p < 0.001; Figure 10B), SCC (r = 0.33, p < 0.001; Figure 10C), and LCC (r = 0.39, p = 0.015; Figure 10D). This evidence concerns the gene VEGFA and non-small cell lung carcinoma.
