ESTRO 2021 Abstract Book
eHR that captures the patient’s data before the diagnosis and then, through Natural Language Processing (NLP), analysis and categorization of all data to transform source information into structured data has been performed. Thereafter, an Artificial Intelligence method was developed to support the clinical staff in their decision with regards to tumor staging and to help them identifying the most complex cases where deeper analysis and discussion were required (e. g. conflicting information from different exams) (Figure 1).
Results In the first round, the system has been used to retrieve all the eHR for the 96 patients with LACC. This was the training set of the study, with validated 2009 FIGO staging classification ranging from I B2 to IV A as output. For these patients, available eHR included MR, EUA, and PET-CT diagnostic reports. The system has been able to classify all patients belonging to the training set and - through the NLP procedures - the clinical features were analyzed and classified for each patient. A second important result was the setup of a predictive model to evaluate the patient’s staging. Our approach has led to predict patient’s staging within an accuracy of 94%. Lastly we created a user-oriented operational tool targeting the MTB who are confronted with the challenge of large volumes of patients to be diagnosed in the most accurate way. The resulting decision support system is summarized in Figure 1. Furthermore, the MTB Smart DA was tested in a 13 LACC patients validation cohort showing an accuracy of 93%, in line with the training set performances. Conclusion This is the first proof of concept concerning the possibility of creating a smart virtual assistant for the MTB. A significant benefit could come from the integration of these automated methods in the collaborative, crucial decision stages.

Our objective was to describe patterns of 0.35T-MRgRT utilization in Europe and Asia among early adopters of this novel technology. Materials and Methods
