Area of Science:

  • Hepatopancreatobiliary surgery
  • Medical imaging analysis
  • Surgical oncology

Background:

  • Preoperative planning for pancreatic head cancer is challenging, demanding specialized expertise.
  • Assessing tumor resectability, particularly concerning vascular involvement, is critical for surgical success.
  • Existing methods may not fully capture the complexities of tumor anatomy and its relation to vital structures.

Purpose of the Study:

  • To evaluate the added value of 3D patient models and CAD algorithms in determining pancreatic head tumor resectability.
  • To compare the performance of experts using CT scans alone versus CT scans with 3D models and CAD.
  • To assess the impact on perceived preoperative needs, decision-making quality, and confidence.

Main Methods:

  • A pilot study involving 14 hepatopancreatobiliary experts from eight institutions.
  • A crossover design was used, with experts assessing resectable and borderline resectable cases.
  • Participants were divided into three groups: controls (CT scan), 3D group (CT scan and 3D models), and CAD group (CT scan, 3D models, and CAD).

Main Results:

  • The CAD group showed a significantly improved perceived ability to determine tumor-vessel contact degrees and length compared to controls.
  • Experts in the CAD group predicted lower degrees of tumor-vessel contact for borderline resectable tumors.
  • The 3D group demonstrated higher confidence in predicting the need for vascular resection across all cases.

Conclusions:

  • Computer-aided detection, incorporating 3D models, enhances experts' accuracy in assessing vessel involvement in pancreatic cancer.
  • These advanced visualization techniques support the development of improved diagnostic and therapeutic strategies for pancreatic cancer.
  • The findings suggest a potential role for CAD and 3D modeling in optimizing preoperative planning and surgical outcomes.
