A Prospective Study on the Application of Para-aortic Lymph Node Metastasis Prediction Model in Locally Advanced Cervical Cancer and Its Effect on Prognosis
The goal of this prospective single-arm trial is to investigate the accuracy and feasibility of the para-aortic lymph node metastasis prediction model in locally advanced cervical cancer, as well as its impact on patients' prognosis. The main questions it aims to answer are: * Is the para-aortic lymph node metastasis prediction model accurate and feasible? * Whether the para-aortic lymph node metastasis prediction model can affect the prognosis of patients.
• In 2018, the International Federation of Obstetrics and Gynecology (FIGO) stage was Ib3 IIA2-IVA;
• It was treated initially without surgical and chemotherapy.
• Squamous cell carcinoma, adenocarcinoma and adeno-squamous cell carcinoma were confirmed by histopathology.
• Pelvic MRI ± abdominal CT or MRI or PET/CT were performed before treatment.
• ECOG score:0 \
• The expected survival time\>6 months;
• There is no absolute contraindication of surgery and and chemoradiotherapy and the patients with good compliance.
