Abstract: Objective The aim of this study was to analyze 10 years survival status of gastric cancer and its influencing factors in three cities of Liaoning province. Methods Four hundred cases of gastric cancer randomly selected from the tumor incidence report database in three cities of Liaoning province from 2000 to 2002 were actively followed up to obtain the diagnosis,treatment and survival status of the patients.The life table method was used to calculate the observed survival rate(OSR),and the Ederer II method was used to calculate the relative survival rate(RSR).The multivariate Cox model was used to analyze the factors affecting survival. Results The 10-year OSR,RSR and T50 of gastric cancer in the three cities of Liaoning province were 14.3%,19.1%,and 12.3 months,respectively.The 10-year OSR,RSR and T50(41.6%,53.7% and 69.0 months)of stage Ⅰ~Ⅱ cases were significantly higher than those of stage Ⅲ(9.1%,14.1% and 14.7 months)and stage Ⅳ(3.0%,4.1% and 6.1 months).The 10-year OSR,RSR and T50(20.8%,27.7% and 20.8 months)of patients treated with surgery were significantly higher than those of non-operative cases(2.6%,3.9% and 4.9 months).The 10-year OSR,RSR and T50(21.1%,23.2% and 14.0 months)in the 0~64 years old group were significantly higher than those in the 65+ years old group(8.9%,15.7% and 10.4 months).There were no significant differences in the 10-year OSR,RSR and T50 between males and females.The results of multivariate analysis showed that diagnosis staging,treatment methods and age had significant impact on the 10-year relative survival rate of gastric cancer. Conclusion The 10-year relative survival rate of gastric cancer(19.1%)in three cities of Liaoning province was lower than that of Europe and America(25.4%~30.7%)and Korea(48.7%)in the same period.The low rate of early diagnosis and standardized diagnosis and treatment may be the main reasons.
