Cervical Cancer
Conditions
Brief summary
The importance of radioresistance in cervical cancer treatment failure indicates that certain biomarkers may be useful for cervical cancer treatment individualization. However, to date, no study has analyzed the role of the gene expression signature of the three RNA species (ANXA2-NDRG1-STAT1) to predict radiosensitivity/resistance in cervical cancer patients undergoing exclusive CTRT. The previously validated three-gene signature may enable stratification in LACC patients treated with the current standard of care, represented by exclusive CTRT.
Detailed description
The importance of radioresistance in cervical cancer treatment failure indicates that certain biomarkers may be useful for cervical cancer treatment individualization. Several biomarkers of cervical cancer radioresistance have been previously studied and proposed; however, none of these has been the subject to further clinical studies and implemented into clinical practice. Recently, a panel of three protein coding genes (ANXA2-NDRG1-STAT1) differently expressed in radiosensitive LACC patients compared with the radioresistant ones, has been proposed by our institution. The population of LACC patients included in a previous study was treated with neo-adjuvant CTRT followed by radical surgery. However, to date, no study has analyzed the role of the gene expression signature of the three RNA species (ANXA2-NDRG1-STAT1) to predict radiosensitivity/resistance in cervical cancer patients undergoing exclusive CTRT. The previously validated three-gene signature may enable stratification in LACC patients treated with the current standard of care, represented by exclusive CTRT.
Interventions
PROCEDURETumor tissue
Each newly diagnosed patient with LACC who meets the inclusion criteria will undergo cervical cancer biopsy either during the outpatient clinical examination or during examination during anesthetic. Part of the biopsy will be sent for histopathological analysis, while the remaining tissue will be embedded in OCT compound and immediately frozen at -80°C prior to transfer to biobank for subsequent analysis.
PROCEDUREBlood sample
Every patient will undergo a peripheral venous blood sample which will be processed to analyze the presence of the proteins codified by three RNA species (ANXA2-NDRG1-STAT1). This blood sample will be performed before starting the treatment with exclusive CTRT.
