简要总结
The para-aortic lymph node involvement in the advanced stage of cervical cancer is a poor prognostic factor for overall survival. Concomitant chemo-radiotherapy has become the standard treatment for advanced cervical cancer. In case of para-aortic lymph node involvement, an extension of radiotherapy fields is recommended.
A prospective multicentre study shown that the survival rate of patients with node ≤ 5 mm and which benefited from the expansion of radiotherapy fields was identical to the survival of pN0 patients.
However, due to a specific disease, this technique should not be performed in all patients. It is necessary to reliably select patients with retroperitoneal lymph node involvement. For this, it is recommended that prior to the concurrent chemo-radiotherapy, nodal staging surgery with a definitive histological analysis.
So we propose to use molecular diagnostic test OSNA (One Step Nucleic Acid Amplification) to improve lymph node metastasis detection sensitivity to achieve ultra-staging compared to conventional histology.

So we suggest using molecular diagnostic test OSNA (One Step Nucleic Acid Amplification) to improve lymph node metastasis detection sensitivity to achieve ultra-staging compared to conventional histology.
We propose to consider a new concordance study to assess the feasibility of the technical OSNA in a new indication: cervical cancer.

结局指标
主要结局
compare the performance of OSNA for the detection of lymph node metastases in advanced cervical cancer
时间窗: 15 days between surgery and OSNA results
The main objective is to compare the performance of OSNA to both conventional methods and intensive histological analysis, for the detection of lymph node metastases in advanced cervical cancer. The evaluation criteria is : * Determination of number of lymph node metastases expressed in a size in mm for conventional and intensive histological analysis. * Determination of the number of lymph node metastases expressed in a number of copies in molecular biology.
