局部晚期宫颈癌癌灶动脉血管网特点及意义

Characteristics and significance of arterial vascular network in locally advanced cervical cancer

宫颈癌的诊断是基于妇科各种检查,在诊断上存在主观性强,难以精确诊断宫旁组织受侵程度以及膀胱直肠浸润程度等问题,尤其是局部晚期宫颈癌(locally advanced cervical cancer,LACC)。LACC还有较多的高危因素,预后不良,对治疗方式的选择一直以来争议较大。通过对LACC数字化三维动脉血管网的定性定量分析,可以判断宫颈癌灶的局部大小、浸润深度,通过供血动脉来源及血流特点来精确诊断癌灶侵犯阴道、宫体、宫旁及邻近器官的情况及范围。通过LACC数字化三维动脉血管网的分析,为选择合适的手术方式并评估手术难度及预后提供依据。

The diagnosis of cervical cancer is based on gynecological examinations.It is difficult to accurately diagnose the degree of invasion into parametrial tissue and the invasion into bladder and rectum,especially in locally advanced cervical cancer（LACC）.LACC also has many high risk factors and poor prognosis.The choice of treatment has always been controversial.By qualitative and quantitative analysis of LACC digital three-dimensional arterial network,the local size and depth of invasion in cervical cancer were judged,and the extent of invasion in vagina,uterine corpus,parametrium and adjacent organs were accurately diagnosed by the source of blood supply artery and characteristics of blood flow.The analysis of LACC digitized three-dimensional arterial network provides the basis for choosing the appropriate operation method and evaluating the difficulty and prognosis of the operation.
