Adjuvant Chemotherapy in cfHPV-DNA Plasma Positive Patients: A Biomarker In Locally Advanced Cervical Cancer

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.
