BACKGROUND
Borrmann type IV gastric carcinoma carries a poor prognosis, even if curatively resected. The benefit of a lymphadenectomy is unknown.
STUDY DESIGN
A retrospective study was designed to evaluate whether improvements have been made in the treatment of type IV gastric carcinoma over the past decade. The 345 patients with type IV carcinoma who underwent laparotomy within a recent 16-year period were split into two groups: one group of patients who underwent laparotomy between 1977 and 1985, and the other between 1986 and 1992. Survival data were compared between these two groups and prognostic factors for type IV gastric carcinoma were assessed by multivariate analysis.
RESULTS
A significant difference in survival was observed between the groups, both of which underwent curative resection, despite a lack of difference in background factors. The improvement was more prominent among patients with nodal metastases and insignificant among patients without nodal metastases. Multivariate analysis identified nodal metastasis as a major independent prognostic factor.
CONCLUSIONS
An improvement in outcome was presumably achieved through extended lymphadenectomy. However, the survival rate remains unsatisfactory, and further advances in the treatment of this disease are needed.
