D2 lymphadenectomy in the management of gastric cancer

Background Gastric carcinoma is a significant cause of death in Ireland. Surgery offers the best option of cure, but the five-year survival following resection remains dismal at 10–15%. Experience from Japan and from some Western units suggest that an extended (D2) lymphadenectomy in association with gastrectomy increases the prospect of cure, but concern about the morbidity and mortality of this operation and lack of evidence from randomised studies has limited its acceptance.
Aims This study reports the experience of a specialist upper gastrointestinal unit with D2 gastrectomy in a four-year audit.
Methods Sixty-two resections were performed for gastric cancer. Results Nineteen patients were deemed unsuitable for the D2 procedure and underwent a more limited lymphadenectomy (DO or D1). Forty-three patients underwent D2 resection, 12 with an oesophagogastrectomy, 22 with total gastrectomy and nine with a sub-total distal resection. Eight patients undergoing D2 resection had extended resections, five with splenectomy and three with a distal pancreatectomy. Post-operative complications occurred in 31% of patients. Thirty-day and 90-day mortality were zero. Median survival was 822 days in the D2 group (range 120–1,320).
Conclusions These results show that a D2 gastrectomy can be performed with a low morbidity and mortality and a median survival of greater than two years.
