Study Description

Brief Summary: This is an international, multicenter and randomized open-label phase III study designed to demonstrate, in patients with stage IIIC1 cervical cancer, whether para-aortic lymphadenectomy followed by tailored chemoradiation is associated with increased disease-free survival compared to patients staged with FDG-PET/CT only followed by chemoradiation. The planned sample size is 510; including 200 patients in France. In this trial, patients will be assigned in one of the two following treatments arms: * Arm A (control arm): Standard chemo-radiotherapy and brachytherapy according to EMBRACE II and ESGO/ESTRO recommendations. * Arm B (experimental arm): Pretherapeutic para-aortic lymphadenectomy followed by tailored chemo-radiotherapy and brachytherapy. Each patient will be followed up for 5 years. A cost-utility study will be performed in patients included in France. Other countries could be involved in this specific study. It will assess the incremental cost-utility ratio (cost per QALY gained) of para-aortic lymphadenectomy followed by tailored chemo-radiation in patients with positive PALN compared to patients staged with PET/CT only followed by chemo-radiation. This study also has ancillary objectives: * Biologic: To study T cell exhaustion, immune changes during chemoradiation, HPV ctDNA dynamic evolution, and the par-aortic lymph node as a premetastatic niche. * Radiomics: To study the contribution of radiomics and FDG-PET/CT metabolic parameters to predict para-aortic lymph node involvement and clinical outcome. * Senti-PAROLA: To evaluate the accuracy (Sensitivity, specificity, positive and negative predictive value) of the para-aortic sentinel lymph node (SPA) for PALN staging, and to evaluate the prognostic value of low volume metastasis of SPA.
