Researchers have developed a deep learning framework to predict patient response to neoadjuvant chemotherapy for ovarian cancer using CT scans. The model analyzes 3D lesion masks derived from pre-treatment CT images, encoding slices and aggregating them into a volumetric representation. This approach combines classification loss with contrastive regularization and hard-negative mining to better distinguish between responders and non-responders. Tested on a cohort of 280 patients, the model achieved a ROC-AUC of 0.73, suggesting its potential as an imaging-based stratification tool. AI
