| Sumario: | Objective: Esophageal cancer is a very common disease in north of Iran. There is no information regarding the survival rates in this area. This study determined 5-year survival rate in patients with esophageal cancer referred to Shahid Rajaii radiotherapy center in Babolsar. Methods: A descriptive-analytical (Historical cohort) study has been conducted on the basis of information that presented in medical files of 230 patients with esophageal cancer at this center (1992-1997), using nonrandom convenient sampling method. The survival analysis was performed by nonparametric Kaplan-Meier method. Findings: The results show that 59.1% of patients were male. The mean age of patients was 62.2 years. In both sexes, the frequency of esophageal cancer in the age range of 60-69 years has been more than other age groups. The survival rate at 1 and 5 year has been 42% and 8% respectively. There was a significant difference in survival rates in terms of the age and sex (P=0.02, P<0.01, respectively) females and patients under 50 years had better survival rate. There was no significant difference on the basis of the histologic findings, anatomical location and the type of treatment of tumor in the survival rate. Conclusion: The results indicated that esophageal cancer has poor prognosis. In this study, 5-year survival rates in patients with esophageal cancer are consistent with the remarked statistical information that was studied in European countries and north America, but it has poorer survival rates in comparison to remarked statistical information that was studied in China and Japan. |
