Extended lymphadenectomy (D2) in patients with early gastric cancer

Abstract: Aims: To investigate the survival benefit of extended lymphadenectomy (D2) in EGC patients in one European Institution. Methods: A review was made of our prospective gastric database from January 1980 to December 2001. Of 527 patients with primary gastric adenocarcinomal 119 with EGC underwent potentially curative resection (R0) with D2 Lymphadenectomy. Results: There were two post-operative deaths. Of the 117 evaluable cases, 96 were classified as NO and 21 as N+, with metastases in the perigastric lymph nodes (level. 1) in 13, and beyond this site (level 2) in eight. Five-year survival was 85.9 and 83.0% in NO and N+ patients, respectively. During a median foltow-up of 90 months, five of the eight patients with level 2 metastases died of recurrent disease and three were alive. The estimated survival benefit for 119 patients with EGC was 2.5% (3/119 cases). Conclusions: In patients with EGC, metastases to level 2 are rare. Our results indicate that D2 lymphadenectomy has a limited survival benefit and that in these cases a less extensive Lymphadenectomy (D1) could be performed.
