Lymph Node Dissection Strategies in Esophageal Cancer

Esophageal cancer frequently spreads to regional lymph nodes, and the extent of nodal clearance is a key determinant of long-term survival. Traditional approaches range from two-field lymphadenectomy, which encompasses mediastinal and abdominal stations, to three-field dissection that adds cervical nodes. Surgeons balance oncological benefit against procedural morbidity, with more extensive clearance offering improved staging accuracy and potential survival advantage at the cost of added risk. Tailored strategies now consider tumour location, histological subtype and patient fitness. Upper thoracic tumours often warrant inclusion of supraclavicular zones, whereas distal lesions may prioritise perigastric and lower mediastinal stations. Sentinel lymph node navigation aims to personalise the scope of dissection, reducing unnecessary clearance. Advances in imaging, artificial intelligence and robotic assistance seek to map lymphatic drainage intraoperatively and predict occult metastases preoperatively. Integration of neoadjuvant therapy with precise nodal staging has reshaped surgical planning, enabling selective dissection of metabolically active or radiologically suspicious nodes. Minimally invasive and robotic platforms facilitate fine dissection with reduced trauma. Globally, the emphasis is shifting towards evidence-based, anatomy-driven templates that optimise oncological control while preserving quality of life.
