宫颈癌是常见的妇科恶性肿瘤,发病率位居第2位,仅次于女性乳腺癌[1]。大多数宫颈癌患者主要死于宫颈癌的复发或转移侵润其它远处组织而引起的一系列临床继发症状,而肿瘤临床治疗的难题也正是肿瘤的浸润与转移。医学界研究认为多种生物因子在宫颈恶性肿瘤的外部浸润转移过程中,起了很大作用,因此明确这些因子的生物学基础,对以后宫颈癌预后的判断有重要的价 Cervical cancer is a common gynecological malignancy, the incidence rate ranked No. 2, second only to female breast cancer [1]. Most cervical cancer patients die of cervical cancer recurrence or metastasis infiltration of other distant tissues caused by a series of clinical symptoms, and clinical treatment of tumor problems is precisely the tumor invasion and metastasis. Medical research that a variety of biological factors in the external invasion and metastasis of cervical cancer played a significant role, so clear the biological basis of these factors, the prognosis of cervical cancer after an important price
