乳腺癌是女性常见的恶性肿瘤,虽然近半个世纪以来其综合治疗取得了重要进展,但每年仍约有30%以上的患者死于复发和转移,而淋巴道与血道转移是导致乳腺癌治疗失败的主要原因,乳腺癌的转移是一个多基因参与、多步骤完成的复杂过程,因此,在分子生物学水平,寻找和分析乳腺癌转移的? Breast cancer is a common malignant tumor in women. Although comprehensive treatment has made significant progress in nearly half a century, more than 30% of the patients still die of recurrence and metastasis each year. Lymphatic and hematogenous metastasis lead to breast cancer treatment The main reason for the failure of breast cancer metastasis is a multi-gene involved in the multi-step complex process, therefore, in the molecular biology level, to find and analyze breast cancer metastasis?
