Abstract

Gynaecological cancers are frequent, with more than 16,000 cases per year in France for 6500 deaths. Few improvements in diagnostic methods, prognostic tools, and therapeutic strategies have occurred in the last two decades. Tumour genomic analyses from, at least in part, the Cancer Genome Atlas have identified some of the molecular alterations involved in gynaecological tumours growth and spreading. However, these data remain incomplete and have not led to dramatic changes in the clinical management of our patients. Moreover, they require invasive samples that are not suitable to objectives like screening/early diagnosis, assessment of treatment efficacy, monitoring of residual disease or early diagnosis of relapse. In the last years, the analysis of circulating tumour biomarkers (also called "liquid biopsies") based on tumour cells (circulating tumour cells) or tumour nucleotides (circulating DNA or RNA) has been massively explored through various indications, platforms, objectives; data related to circulating tumour DNA being the most important in terms of number of publications and interest for clinical practice. This review aims to describe the methods of analysis as well as the observations from the analysis of circulating tumour DNA in gynaecological tumours, from screening/early diagnosis to the adaptation of treatment for advanced stages, through choice of treatments and monitoring of subclinical disease.
