Is there a role for radical esophagectomy

Area of Science:

• Surgical Oncology
• Gastrointestinal Surgery
• Esophageal Cancer Treatment

Background:

• The primary goal of surgery for esophageal and gastroesophageal junction (GEJ) cancer is cure, necessitating complete tumor removal (R0 resection).
• The extent of lymph node dissection, particularly cervical lymph node dissection (third field), remains a controversial aspect of surgical treatment.

Purpose of the Study:

• To evaluate the benefits of extended lymphadenectomy, including the third field, in esophageal and GEJ cancer surgery.
• To assess the impact of extensive lymph node dissection on staging, tumor control, and cure rates.

Main Methods:

• Review of available data and published reports on lymphadenectomy extent in esophageal and GEJ cancer surgery.
• Analysis of outcomes including staging accuracy, locoregional recurrence rates, metastasis, and survival benefits.

Main Results:

• Unforeseen cervical lymph node involvement is found in up to 30% of patients after three-field lymphadenectomy, even in GEJ tumors (up to 20% in T3N+).
• Radical esophagectomy with extensive lymphadenectomy has been associated with locoregional recurrence rates below 10% and delayed onset of recurrence and metastasis.
• Studies indicate a survival benefit with radical esophagectomy and extensive lymphadenectomy, suggesting it offers the best chance for cure.

Conclusions:

• Radical surgery with extensive lymphadenectomy, including the cervical field, provides optimal staging, prolonged tumor control, and improved cure rates for esophageal and GEJ cancer.
• This approach can be performed without increasing hospital mortality or morbidity.
• Survival figures from radical surgery serve as a benchmark for evaluating other treatment modalities.
