Accurately diagnosing esophageal cancer invasion depth preoperatively is crucial. A novel method using Lipiodol Ultra Fluid and calculated ratios achieved 85.7% diagnostic accuracy, aiding treatment decisions.

Area of Science:

  • Gastroenterology
  • Oncology
  • Radiology

Background:

  • Preoperative diagnosis of esophageal cancer penetration is vital for effective treatment planning.
  • Accurate staging guides surgical and therapeutic interventions.

Purpose of the Study:

  • To develop and evaluate a novel preoperative diagnostic method for esophageal cancer invasion depth.
  • To assess the accuracy of this new method compared to histological examination.

Main Methods:

  • Lipiodol Ultra Fluid was injected into the oral side of the lesion.
  • Calculation of 'transfer ratio' and 'section ratio' based on contrast medium spread.
  • Classification of invasion depth into four categories: A0(sm), A0(pm), A1-2, and A3.

Main Results:

  • The developed method achieved an overall diagnostic accuracy of 85.7%.
  • Specific accuracies included A0(sm): 100%, A0(pm): 75%, A1-2: 91.7%, and A3: 80%.
  • The method demonstrated good correlation with histological findings.

Conclusions:

  • The novel method using Lipiodol Ultra Fluid provides a reliable preoperative assessment of esophageal cancer invasion depth.
  • This technique offers a valuable tool for improving treatment strategies and patient outcomes.
