Cancers are the 2nd cause of death, especially gastric and esophagus cancers are among the most fatal cancers in Iran. The aim of the present study is to estimate and compare the survival rates in patients with gastric and esophagus cancers. Materials and Methods: After extracting information of patients with gastric and esophagus cancers registered in cancer registry of Fars province, they followed by telephone contact. Data analysis was carried out by two statistical methods including Kaplan-Meier and Life-table. Results: There were 442 cases with gastric cancer and 161 cases with esophagus cancer. One and five-year overall survival rates using Kaplan-Meier method were 54 and 16 percent percent in gastric cancer and 53 and 9 percent in esophagus cancer patients, respectively. Also, using life-table method overall 1 and 5- year survival rates of gastric cancer were 57 and 16 percent and esophagus cancer were 58 and 10 percent. There was no significant difference between survival rates in above cancers. Conclusion: Results showed that there was no difference between survival rates in above cancers and only a few patients survive 5 years after diagnose of their disease. Therefore, accomplishment of measurements is necessary for improvement of patients’ lifetime.
