  • Consideration of laparoscopic staging as an adjunct in select cases.

    • Main Results:

    • CT scan is effective for initial detection of local invasion and distant metastases.
    • Endoscopic ultrasound (EUS) offers high accuracy for local tumor staging (T and N categories).
    • Laparoscopic staging may be beneficial in specific patient subgroups.

    Conclusions:

    • CT scan and EUS serve complementary roles in the multidisciplinary approach to gastric cancer staging.
    • Further advancements in imaging techniques are expected to enhance staging accuracy.
    • Improved staging will facilitate personalized treatment strategies and better patient outcomes.
