目的:检测不同分子病理特征的乳腺癌患者血清血管内皮生长因子(VEGF)水平,探讨其与新辅助化疗疗效的相关性。方法:通过ELISA方法对75例实施新辅助化疗的患者分别于化疗前、化疗3周期后检测血清VEGF水平,同时通过临床测量、超声检查、核磁共振等方法评估化疗疗效。结果:在腋窝淋巴结转移≥4个的乳腺癌患者中,血清VEGF水平明显高于淋巴结转移<4个的乳腺癌患者[(307.31±101.42) pg/mL vs.(170.16±73.07)pg/mL, P =0.017];在 HER-2(+)乳腺癌中,血清 VEGF 水平较 HER-2(-)患者显著增高[(235.15±88.42) pg/mL vs.(179.82±69.90) pg/mL,P =0.024];不同病理类型、绝经前后及不同激素受体表达状态患者间血清VEGF水平未见明显差异。在新辅助化疗cCR及cPR的患者中,化疗前血清 VEGF 水平分别为(205.75±78.12) pg/mL 和(226.04±89.04) pg/mL,化疗3周期后为(145.15±67.08) pg/mL及(161.27±93.57) pg/mL,两者差异显著(P =0.009,0.014),而在疗效评估为无效(SD+PD)的患者中,化疗前后血清VEGF水平未见明显变化(P =0.577)。结论:血清VEGF水平与乳腺癌的淋巴结转移及HER-2基因表达具有相关性,新辅助化疗可降低乳腺癌患者血清VEGF的水平,能否作为新辅助化疗的疗效判定指标有待进一步研究。
目的:檢測不同分子病理特徵的乳腺癌患者血清血管內皮生長因子(VEGF)水平,探討其與新輔助化療療效的相關性。方法:通過ELISA方法對75例實施新輔助化療的患者分彆于化療前、化療3週期後檢測血清VEGF水平,同時通過臨床測量、超聲檢查、覈磁共振等方法評估化療療效。結果:在腋窩淋巴結轉移≥4箇的乳腺癌患者中,血清VEGF水平明顯高于淋巴結轉移<4箇的乳腺癌患者[(307.31±101.42) pg/mL vs.(170.16±73.07)pg/mL, P =0.017];在 HER-2(+)乳腺癌中,血清 VEGF 水平較 HER-2(-)患者顯著增高[(235.15±88.42) pg/mL vs.(179.82±69.90) pg/mL,P =0.024];不同病理類型、絕經前後及不同激素受體錶達狀態患者間血清VEGF水平未見明顯差異。在新輔助化療cCR及cPR的患者中,化療前血清 VEGF 水平分彆為(205.75±78.12) pg/mL 和(226.04±89.04) pg/mL,化療3週期後為(145.15±67.08) pg/mL及(161.27±93.57) pg/mL,兩者差異顯著(P =0.009,0.014),而在療效評估為無效(SD+PD)的患者中,化療前後血清VEGF水平未見明顯變化(P =0.577)。結論:血清VEGF水平與乳腺癌的淋巴結轉移及HER-2基因錶達具有相關性,新輔助化療可降低乳腺癌患者血清VEGF的水平,能否作為新輔助化療的療效判定指標有待進一步研究。

Objective To observe the levels of serum VEGF in different molecular subtypes of breast cancer and explore its relationship with response to neoadjuvant chemotherapy. Methods Levels of serum VEGF in 110 cases with breast cancer underwent neoadjuvant chemotherapy were detected by ELISA prior to and after 3 cycles of neoadjuvant chemotherapy. Clinical response to neoadjuvant chemotherapy was evaluated by physical examination and ultrasonography. Results Levels of serum VEGF were significantly increased in breast cancer patients with≥4 lymph node metastasis than those with < 4 lymph node[(307.31 ± 101.42) pg/mL vs. (170.16 ± 73.07) pg/mL,P = 0.017]. Patients with positive HER-2 status had significantly higher levels of serum VEGF than those with HER-2 negative status [(235.15 ± 88.42 ) pg/mL vs. (179.82 ± 69.90) pg/mL, P = 0.024]. No significant difference was observed among age , menopausal status and hormone status. In patients with neoadjuvant chemotherapy of cCR and Cpr,the mean levels of serum VEGF were (205.75 ± 78.12) pg/mL and (226.04 ± 89.04) pg/mL, respectively. After 3 cycles of chemotherapy, levels of serum VEGF decreased to (145.15 ± 67.08) pg/mL and (161.27 ± 93.57) pg/mL. There was significant difference between two groups (P=0.009,0.014). In patients with SD or PD response, no significant difference was observed between levels of serum VEGF before and after chemotherapy (P = 0.577). Conclusions Levels of serum VEGF in breast cancer correlate with lymph nodes metastasis and HER-2 status and may decrease after neoadjuvant chemotherapy. However,whether or not the levels of serum VEGF can be used as a biomarker for response to neoadjuvant chemotherapy needs more further studies.
