简要总结
The objective of the trial is to evaluate if adjuvant (chemo)radiation is associated with a disease-free survival benefit after radical surgery in patients with intermediate risk cervical cancer. The primary endpoint of the study is the disease-free survival from the day of randomisation. A total of 514 patients are required to achieve 80% power on 5% significance level with non-inferiority margin of 5% to test the difference between the ARMs using Cox proportional hazards model. The maximal tolerated margin for non-inferiority in 2-year DFS is 5% (including expected drop-out rate of 10%).
详细描述
The role of adjuvant (chemo)radiotherapy in intermediate risk (IR) cervical cancer patients is controversial, supported by single randomised GOG 92 study performed more than 20 years ago. Intermediate-risk group is defined as lymph node negative but with a combination of negative prognostic factors (tumour size >2 cm, lymphovascular space invasion, deep stromal invasion >2/3). Recent retrospective studies showed excellent local control in intermediate risk group patients after radical surgery with no additional adjuvant treatment.
CERVANTES trial is designed to bring level A evidence on the role of adjuvant treatment in IR patients in an international, prospective, randomised study. Patients will be registered into the trial before surgery and randomised after the final pathology report has been received into ARM A, with no additional treatment, and ARM B, receiving adjuvant (chemo)radiotherapy. Quality assurance program will be in place for both, radical surgery and adjuvant treatment.

结局指标
主要结局
Disease-free survival
时间窗: Analysed 3 years after randomization of the last patient.
Calculated as an interval from the day of randomisation until diagnosis of recurrence: (a) unequivocal finding on imaging by subjective radiological assessment; b) suspicious recurrence on imaging either confirmed by biopsy or supported by other signs (disease progression on imaging or progression of symptoms); (c) physical examination supported by clinical evidence (i.e., symptoms or progression); or (d) death caused by disease or death of unknown cause.
次要结局
- Overall survival(Analysed 6 years after randomization of the last patient.)
- Health-related quality of life based questionnaire(Analysed 3 years after randomization of the last patient.)
- Pelvic disease-free survival(Analysed 3 years after randomization of the last patient.)
- Treatment-related adverse events based on Common Terminology Criteria for Adverse Events v5.0(Analysed 3 years after randomization of the last patient.)
