CNN-based tumor progression prediction after thermal ablation with CT imaging

In person: 23 February 2022 • 5:30 PM - 7:00 PM PST

Abstract

For patients with advanced colorectal cancer, liver metastasis is the most common kind of distant spread. Resection of the metastasis is often not possible due to tumor size and location. As a result thermal ablation is now part of international guidelines. However, a significant number of patients experience regrowth. This is currently only identified 4 months after treatment (at the earliest). We have trained a CNN model that can predict regrowth using CT scans at baseline and directly after ablation therapy, which achieves an area under the receiver operating characteristic curve of 0.72 from a dataset containing 120 lesions.
