Background and Objective: Breast cancer is the most common cancer and the major cause of cancer death among women. The survival rate for breast cancer indicates the percentage of people that survive the disease for a specified period of time after diagnosis. The aim of this study was analyzing the survival rate of patients with breast cancer in East Azarbaijan province.

Materials and Methods: This study was a retrospective analysis. The statistical population included 79 breast cancer patients of East Azarbaijan province. Data such as age at diagnosis was obtained from the medical records and other data such as the status of survival/death was found out through telephone interview. For survival evaluation, the Kaplan-Meier method was used. The effect of covariates such as age at diagnosis on the survival duration was calculated with the Log - Rank (Mantel - Cox) method.

Results: The 1, 3 and 5 year-survival rate were calculated to be 98%, 88% and 82%, respectively. Age at the time of diagnosis affected the survival rate of patients; patients over 40 years at the time of diagnosis had a higher survival rate than patients under 40 years (p<0.05).

Conclusion: Survival rate analysis showed the similar or higher survival rate of breast cancer patients of East Azarbaijan in comparison with other regions in Iran. The survival rate in patients older than forty years at the time of diagnosis was significantly higher than patients younger than forty. However a study on more patients is recommended to obtain more clear results.
