Background:
Cancer is a non-communicable disease that is considered deadly in many cases. In recent years, the mortality rates from breast cancer have increased with increasing incidences. The present study was conducted to determine five year survival of women with breast cancer in Yazd, in the central region of Iran.
Materials And Methods:
In a prospective study, data were obtained from the patient's medical records with breast cancer that were referred to the Shahid Sadoughi hospital and radiotherapy center from 2002-2007 and followed up for 5 years. The data collected were analyzed by SPSS/16 and Kaplan-Meyer test and log-rank test and Cox proportional hazard model was used.
Results:
The mean age of breast cancer diagnosis was 48.3±11.7 years. The 1-, 2-, 3-, 4- and 5-year cumulative survivals for breast cancer patients were 95%, 86%, 82%, 76% and 70%, respectively. There were significant differences with age distribution (p=0.006). A significant decrease in the 5-year survival in patients with involvement of lymph nodes was lso observed.
Conclusions:
Education for early diagnosis in women must be considered and these findings support the need for breast cancer screening programs.
