Abstract

Background: Gastric cancer remains as one of the leading causes of death worldwide. In
patients with gastric cancer, the survival rate after diagnosis is relatively low. The present study
aimed to evaluate the impact of demographic factors in estimation of survival rate in patients with
gastric cancer in order to develop updated documents in these patients.
Materials and Methods: All gastric cancer patients registered in Fars cancer registry were
entered in the study. Vital status of the patients was asked by telephone contact. Survival rates were
estimated using Kaplan-Meier method and compared by Log-rank test. All calculations were
performed using STATA (v.8) software. The p value<0.05 was considered as statistically
significant.
Results: Mean and median of survival time was 21.49 and 12.60 months, respectively. A
statistically significant difference was seen in survival rates between age groups and type of first
treatment. Also, no significant variation was observed in estimation of survival function between
other factors (P>0.05).
Conclusion: Our results showed that the survival rates of gastric cancer patients in our study
were relatively low. Late diagnosis and delayed therapy are important reasons for low survival in
these patients. Therefore, improving public education about primary symptoms of gastric cancer by
media is recommended.
