Brief summary
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.
Detailed description
A prospective, randomized, multicenter, national, superiority, parallel, clinical trial, design to evaluate the use of adjuvant chemotherapy in patients with locally advanced cervical cancer selected by cfDNA-HPV biomarker. Patients will be randomized by stratified randomization process to belong to one of the groups: control (Group B) or intervention (Group C), emphasizing homogeneity of risk factors between them. A randomized list will be generated by using a suitable software, using variable size blocks (2 or 4), with stratification for site and staging. The confidentiality of the randomization list will be maintained through an automated, centralized, Internet-based randomization system, available 24 hours a day (RedCap). Selected patients must receive standard treatment based on concomitant chemoradiotherapy regime, with dose of radiation of 40-50 greys (Gy) (considering additional boost of 10-15 Gy in lymph nodes, radiologically or surgically, compromised) and brachytherapy of 30-40 Gy and cisplatin 40mg/m2 weekly. After four weeks of the end of treatment, a qualitative and quantitative research of cfHPV-DNA in plasma of patients will be conducted. Those with a negative qualitative research result will leave the study. Patients who have positive research for plasma 16, 18, 26, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 69, 73, 82 cfHPV-DNA at the end of chemoradiotherapy treatment will be randomized to receive two additional cycles of adjuvant chemotherapy or observation. In those cases in which the duration of radiochemotherapy treatment exceeds 84 days, patients must undergo imaging examination (chest, abdomen and pelvis CT) in order to exclude pre-randomization metastatic disease. 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.
Interventions
Two additional cycles of cisplatin-based adjuvant chemotherapy 50mg/m2 D1 and gemcitabine 1000mg/m2 D1 and D8 at every 21 days.
Patients will be followed with plasma cfDNA-HPV, computed tomography (CT) scan of the thorax and magnetic resonance (MRI) of abdomen and pelvis and clinical and gynecological examination at every four months.

Intervention model description
A prospective, randomized, multicenter, national, superiority, parallel, clinical trial, design to evaluate the use of adjuvant chemotherapy in patients with locally advanced cervical cancer, selected by cfDNA-HPV biomarker. Intervention arm will count on application of two additional cycles of cisplatin-based adjuvant chemotherapy 50mg/m2 D1 and gemcitabine 1000mg/m2 D1 and D8 at every 21 days. Randomization will be allocated 1:1. Participants will be followed at every 4 months, in person or by phone. Primary endpoint is progression-free survival time.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression free survival | 120 days | Progression-free survival will be calculated from the date of randomization until the date of progression, whether local or distant, or death. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall survival | 120 days | 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 | 120 days | 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) | 21 to 120 days | 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 | 7 to 120 days | 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. |
