- Abstract
Objective: To evaluate whether the introduction of tumor volume as newparameter in the MRI assessment could improve both concordance between preoperative and postoperative staging, and the identification of histological findings. Methods: A retrospective observational study with 127 patients with endometrial cancer (EC) identified between 2016 and 2021 at the Juan Ramon Jimenez University Hospital, Huelva (Spain) was carried out. Tumor volume was measured in three ways. Analyses of Receiver Operating Characteristic (ROC) curve and the area under the curve (AUC) were performed. Results: Although preoperative MRI had an 89.6% and 66.7% sensitivity for the detection of deep mucosal invasion and cervical stroma infiltration, preoperative assessment had an intraclass correlation coefficient of 0.517, underestimating tumor final stage in 12.6% of cases, with a poor agreement between preoperative MRI and postoperative staging (k=0.082) and low sensitivity (14.3%) for serosa infiltration. The cut-off values for all three volume parameters had good/excellent AUC(0.73-0.85), with high sensitivity (70-83%) and specificity (64-84%) values for all histopathological variables. Excellent/good agreement was found all volume parameters for the identification of deep myometrial invasion (0.71), cervical stromainfiltration (0.80), serosa infiltration (0.81), and lymph nodemetastases (0.81). Conclusion: Tumor volume measurements have good predictive capacity to detect histopathological findings that affect final tumor staging andmight play a crucial role in the preoperative assessment of patients with endometrial cancer in the future.
