摘要: This paper describes the construction, validation and use of a simple prognostic score suitable for predicting survival patients undergoing curative gastric resection. Using death from all causes as outcome, significance age, sex, tumour site, stage disease (nodal status wall invasion), surgical treatment histological type was investigated in set 213 recruited multi-centre clinical trial. A Weibull multiple regression model adopted to evaluate joint effect these variables on survival. From full model, containing variables, final parsimonious obtained by means backward selection procedure. The is based including four which are easily detected every institution: invasion, site tumour, nodal status. Three groups with different probabilities surviving 5 years surgery were identified: group I (survival probability ≥ 70%), II (30%–69%) III (
