ERBB2 and breast cancer: During the first, second and third years after surgery, the VEGF levels in the patients with all of the selected molecular subtypes of BC (Luminal A subtype 97.34 pg/mL; 83.83 pg/mL; 77.05 pg/mL; Luminal B subtype 84.12 pg/mL; 80.01 pg/mL; 83.49 pg/mL; Luminal B HER2 positive subtype 85.07 pg/mL; 97.98 pg/mL; 87.00 pg/mL) were significantly lower compared to the preoperative concentrations (Luminal A subtype p < 0.001; p < 0.001; p < 0.001; Luminal B subtype p = 0.001; p < 0.001; p = 0.005; Luminal B HER2 positive p < 0.001; p < 0.001; p = 0.001 respectively).
