About this trial
This study hypothesizes that patients who persist with cell-free human papillomavirus deoxyribonucleic acid (cfHPV-DNA) plasma expression at the end of standard treatment, can derive the benefit of using adjuvant chemotherapy in locally advanced cervical cancer (CC). After standard treatment based on concomitant chemoradiotherapy regime, a qualitative and quantitative research of cfHPV-DNA in plasma of patients will be conducted. Patients who have positive research for plasma cfHPV-DNA at the end of chemoradiotherapy treatment will be randomized to receive two additional cycles of adjuvant chemotherapy or observation. Patients will be followed with conduction of computed tomography (CT) scan of the thorax and magnetic resonance (MRI) of abdomen and pelvis and clinical and gynecological examination at every four months.

Treatment groups
Trial outcomes
Primary outcomes
Progression free survival
Progression-free survival will be calculated from the date of randomization until the date of progression, whether local or distant, or death.
Secondary outcomes
Overall survival
Pverall survival will be calculated from the date of randomization until death or last follow-up. Follow-up will be updated at each consultation and the following possibilities will be considered: living without disease, living with disease, death from cancer, death from another cause and loss of follow-up.
Overall response rate
Response assessment will be performed using RECIST 1.1 (2009) criteria through pelvic MRI. Thus, complete response (CR) will be considered the disappearance of all lesions. Partial response (PR), reduction (30%) in the sum of the largest diameters of target lesions, when compared to the initial examination. Disease progression (PD): increase (20%) in the sum of the largest diameters of the lesions, when compared to the initial examination or the appearance of new lesions. Stable disease: does not meet criteria for PR or PD.
Quality of life measures (EORTC QLQ-C30 and QLC-CX24)
Generic quality of life measures (EORTC QLQ-C30) will be assessed during medical consultations in this clinical study, considering that this questionnaire alone does not adequately assess specific treatment issues that affect the quality of life of women with cervical cancer, a QLQ-CX24 add-on module will also be applied. All questionnaires used in this study are self-administered, however, in those cases where the ability to understand, little education/illiteracy is considered low or when telephone monitoring is in force, the tests will be applied by the researchers, who will seek to read all the questions and help mark answers.
Toxicity according to the Common Terminology Criteria for Adverse Events v.5.0
Toxicity will be classified according to the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 (2017). Hematological (anemia, neutropenia, thrombocytopenia and febrile neutropenia), gastrointestinal (diarrhea, nausea and vomiting), renal (serum creatinine changes) and hepatic (AST and ALT changes) toxicities will be evaluated. Grade 1 and 2 toxicities, together, were considered mild and grade 3 and 4 toxicities were considered severe.
