摘要/Abstract

摘要：

宫颈癌作为妇科肿瘤中发病率最高的恶性肿瘤,临床诊断及分期精准化评估的要求也随着精准治疗模式的发展而不断提高。国内外对于宫颈癌指南的更新也发生了新的变化,2018年国际妇产科联盟（FIGO）更新了宫颈癌的分期标准,相较于之前单独的临床分期,首次提出影像及病理辅助分期,更加准确地评估肿瘤进展。在影像学评估方面,由于磁共振成像（MRI）无电离辐射,具有较好的软组织分辨率和较多的功能成像序列,2021年美国国立综合癌症网络（NCCN）宫颈癌临床实践指南推荐盆腔MRI增强检查作为宫颈癌局部病灶评估的影像学方法。随着MRI技术的临床推广应用及人工智能技术的探索,MRI在宫颈癌诊断的精准评估及治疗后随访都具有较大的应用潜力。根据宫颈癌FIGO分期的进展,探讨MRI在宫颈癌分期评估中的临床应用及研究进展。

Abstract:

Cervical cancer is the tumor with the highest incidence in gynecological malignancies. The requirements for accurate clinical diagnosis and staging evaluation are increasing with the development of precise treatment. New changes have taken place in the update of cervical cancer guidelines at home and abroad. In 2018, the International Federation of Gynecology and Obstetrics (FIGO) updated the surgical staging of cervical cancer, which proposed imaging and pathology-assisted staging for the first time to more accurately assess tumor progression compared to the previous clinical staging alone. In terms of imaging evaluation, since MRI has no ionizing radiation, better soft tissue resolution and more functional imaging sequences, the 2021 NCCN Clinical Practice Guidelines in Cervical Cancer recommends pelvic MRI as imaging for the evaluation of local disease extent. With the clinical application of MRI technology and the exploration of artificial intelligence technology, MRI has great application potential in the accurate assessment of cervical cancer diagnosis and follow-up after treatment. This article will discuss the recent progress and applications of MRI in cervical cancer staging assessment based on the updates of the FIGO staging of cervical cancer.
