Accurate esophageal cancer staging is crucial for survival and treatment. Endoscopic ultrasound with fine needle aspiration (EUS-FNA) is the most effective method for locoregional staging, improving patient management.

Area of Science:

  • Gastroenterology
  • Oncology
  • Radiology

Background:

  • Accurate staging of esophageal cancer is vital for patient survival and guides stage-dependent treatment algorithms.
  • Initial diagnosis is typically made via upper endoscopy and biopsy.
  • Computed tomography (CT) and positron emission tomography (PET) scans are valuable for detecting distant metastatic disease.

Purpose of the Study:

  • To evaluate the role of endoscopic ultrasound (EUS) in the locoregional staging of esophageal cancer.
  • To assess the efficacy of EUS-directed fine needle aspiration (FNA) for tissue diagnosis.
  • To determine optimal staging strategies combining EUS-FNA with imaging modalities.

Main Methods:

  • Endoscopic ultrasound (EUS) was utilized to visualize tumor and surrounding structures for locoregional staging (T and N).

  • EUS-directed fine needle aspiration (FNA) was employed to obtain tissue diagnoses from lymph nodes and liver metastases.
  • Comparison with CT and PET scans for detecting distant disease.

    • Main Results:

    • EUS is the most accurate technique for locoregional staging (T and N) of esophageal cancer.
    • EUS-FNA enables tissue diagnosis of lymph nodes and liver metastases.
    • Combined staging strategies using EUS-FNA with CT or PET scans are optimal.

    Conclusions:

    • Endoscopic ultrasound (EUS) is the gold standard for locoregional staging of esophageal cancer.
    • EUS-directed fine needle aspiration (EUS-FNA) significantly enhances diagnostic accuracy.
    • Integrating EUS-FNA with CT or PET imaging provides comprehensive staging for esophageal cancer management.
