To address this, we developed a deep-learning model capable of accurately delineating both CTV and PTV across multiple uterine malignancies using CT imaging.</p><p><strong>Materials and methods: </strong>We retrospectively collected 602 contrast-enhanced CT scans, comprising 302 cases (cervical and endometrial cancers) from our institution and an additional 300 cervical cancer scans from external centers.

The remaining 300 cervical cancer scans from external centers formed a second external testing cohort to assess model robustness across institutions.
