Area of Science:

Surgical Oncology
Gastrointestinal Cancer Research

Context:

Lymph node metastasis is a primary prognostic indicator in gastric and esophageal cancers.
Early lymphatic spread is characteristic of these gastrointestinal malignancies.

Purpose:

To describe regional lymph node anatomy and define standard and extended lymphadenectomy.
To evaluate the role and benefits of lymph node dissection in gastric and esophageal cancer treatment.

Summary:

This review analyzes surgical literature to assess the impact of lymphadenectomy, especially extended types, on morbidity, mortality, loco-regional recurrence, and survival.
Evidence-based analysis guides practical treatment recommendations for lymph node management in these cancers.

Impact:

Provides evidence-based guidelines for optimizing lymphadenectomy strategies in gastric and esophageal cancer surgery.
Aims to improve patient outcomes by clarifying the benefits of thorough lymph node dissection.
