Abstract
Introduction/Background Introduction: Endometrial cancer (EC) constitutes the fourth most common cancer among women in Europe, and in recent years its incidence has increased significantly. Despite good prognosis for patients with localized disease, about 20% of patients classified as low-risk at surgery, experience disease recurrence. Unfortunately, the therapeutic options for EC extrauterine disease are currently limited, likely related to the innate intra-tumoral heterogeneity (ITH). Consequently, there is an urgent need to identify more effective treatment options and accurate diagnostic methods to improve risk stratification and patient survival. Our consortium aims to generate an algorithm that combines clinicopathologic and molecular characteristics to accurately predict the risk of recurrence of EC and the therapeutic outcomes in high-risk EC.
Methodology Methodology: More than 300 samples, including both prospective samples (uterine aspirates (UA) or cfDNA by liquid biopsies) and retrospective tissue EC samples, have been characterized using immunohistochemistry and molecular techniques. Clinical data have been collected for all samples. This information has been utilized by machine learning and artificial intelligence strategies for decoding a novel predictive algorithm to better stratify the risk of recurrence of EC.
Results Results: Different bioinformatic tools have been used to analyze 198 UAs and 50 tumor samples so far in order to identify a predictive algorithm. This predictor, named ECLAI (personalized clinical management of Endometrial Cancer using Liquid biopsy, genomics and Artificial Intelligence), integrates the clinicopathologic, genomic and molecular tumor characteristics to better stratify the risk of recurrence of EC. Derived from this study we have identified specific molecular patterns that could help to correctly classify high-risk EC.
Conclusion Conclusions: The combined analysis of genetic alterations, clinicopathological features and liquid biopsy allows better stratification of EC post-surgery risk and represents a useful tool to improve the management of the disease.
