Controversy exists about the prognostic value of the histological classifications of gastric cancer commonly used. Recently Goseki proposed a new classifying system based on intracellular mucus production and the degree of tubular differentiation. The aim of this study was to compare Lauren and Goseki classifications with particular emphasis on their prognostic significance. Eighty-nine patients, who underwent potentially curative resections (RO) and radical lymphadenectomy for advanced gastric cancer from September 1988 to April 1996 were analysed. Cox regression model was used to evaluate the prognostic significance of Goseki classification, Lauren classification, age, sex, type of lymphadenectomy, depth of tumour invasion (T), node metastases (N) and number of metastatic nodes. A statistically significant correlation between the different Goseki grades and histology according to Lauren was found (p <0.001). By multivariate analysis the only parameters predictive of long term outcome were depth of tumour invasion, nodal status and histology according to the Lauren classification. Also after excluding the Lauren classification from the analysis, the Goseki histological grading system did not affect survival independently. This study on advanced gastric cancer patients identified depth of invasion, lymph node metastases and Lauren classification as significant independent pathological variables influencing survival. The classification proposed by Goseki did not add anything further to the prognostic informations provided by TNM staging and Lauren classification.
