- Abstract: Surgical resections are the most prevalent curative treatment for primary
liver cancer. Tumors located in critical positions are known to complexify
liver resections (LR). While experienced surgeons in specialized medical
centers may have the necessary expertise to accurately anticipate LR
complexity, and prepare accordingly, an objective method able to reproduce this
behavior would have the potential to improve the standard routine of care, and
avoid intra- and postoperative complications. In this article, we propose CoRe,
an automated medical image processing pipeline for the prediction of
postoperative LR complexity from preoperative CT scans, using imaging
biomarkers. The CoRe pipeline first segments the liver, lesions, and vessels
with two deep learning networks. The liver vasculature is then pruned based on
a topological criterion to define the hepatic central zone (HCZ), a convex
volume circumscribing the major liver vessels, from which a new imaging
biomarker, BHCZ is derived. Additional biomarkers are extracted and leveraged
to train and evaluate a LR complexity prediction model. An ablation study shows
the HCZ-based biomarker as the central feature in predicting LR complexity. The
best predictive model reaches an accuracy, F1, and AUC of 77.3, 75.4, and 84.1%
respectively.
