Based on the finding of higher incidence of VEGFR2 expression in pulmonary SCC cells and its adverse prognostic significance in the present study, it could be hypothesized that higher expression of VEGFR2 in tumor cells may be a predictor of the efficacy of antiangiogenic (or combination of docetaxel and antiangiogenic) therapy, especially in patients with SCC of the lung. Here, KDR is linked to neoplasm.
