VEGF concentrations were higher in bronchial washings from patients with lung cancer after treatment with chemotherapy and irradiation, but none of included patients in this study received such treatment before.37 VEGF concentrations in bronchial secretions from affected side of the lung were not in correlation with any of the tumour features, what possibly reflects the effect of VEGF “washing” to the blood serum, which in contrast reflects such correlations. This evidence concerns the gene VEGFA and lung cancer.
