Abstract

Background: BREAST CANCER comprises 28 percent of all cancers and is the most prevalent cancer in women. It is the second cause of mortality due to cancers in Iran. The objectives of this study were to find and compare risk factors, survival times as well as life expectancies for the different types of surgery in treating BREAST CANCER. Patients and Methods: This study was undertaken on 310 patients who were followed for a ten-year period. Cox and logistic regression models were used to analyze causes of death. The log rank tests were used to compare survival times of different groups while actuarial life table methods were used to find and compare life expectancies of different types of surgery. Results: Statistical analysis of the data showed that, stage (p<0.001), age (p<0.001), benign breast tumor (p<0.01) and family history (p<0.006) had a significant relation to death. The relative mortality risk in patients with a higher stage of disease was 20.5 times while it was 2.62 times in patients with a higher grade of disease. This figure was 4.15 times for patients with a history of benign tumor. The life expectancy for all patients was 10.03 years. This life expectancy was 10.06 and 8.35 years for patients that underwent mastectomy or lumpectomy, respectively. The differences between life expectancy of patients in the stage "early" and in the "locally advanced" and "advanced" stages were statistically significant (p<0.001). Conclusion: It can be concluded that age, stage, grade, family history and benign breast tumor were the most important risk factors related to death in BREAST CANCER.
