Summary
Surgical resection for gastric adenocarcinoma showed varying survival rates. Partial gastrectomy offered better 5-year survival for early-stage disease compared to total gastrectomy, especially in the prospective analysis.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Oncology
Context:
- Retrospective analysis of 196 gastric adenocarcinoma patients undergoing surgical resection between 1983-1997.
- Procedures included total gastrectomy (66%) and subtotal distal gastrectomy (36.2%) with incomplete lymphadenectomy.
- Evaluated postoperative morbidity and long-term survival based on surgical approach and disease stage.
Purpose:
- To compare the outcomes of total versus subtotal distal gastrectomy for gastric adenocarcinoma.
- To assess the impact of lymph node metastasis on survival rates.
- To analyze retrospective and prospective survival data.
Summary:
- Retrospective 5-year survival: Stage I/II - Total gastrectomy 75% (56% with nodes, 94% without); Partial gastrectomy 65% (57% with nodes, 73% without). Stage III/IV - Total gastrectomy 15%; Partial gastrectomy 50%.
- Prospective 5-year survival: Total standard gastrectomy 61%, extended total gastrectomy 76%, partial gastrectomy 91%.
- Overall 5-year survival for Stage I/II was 70% in the prospective study.
Impact:
- Partial gastrectomy demonstrated superior 5-year survival rates, particularly for early-stage gastric adenocarcinoma.
- Findings suggest that surgical approach significantly influences patient outcomes.
- Highlights the importance of staging and lymph node status in predicting survival for gastric cancer patients.
