Survival rate of breast cancer and its related factors in Hormozgan province

Determining the survival rate of cancer patients is a prerequisite for development of prevention and treatment services and implementation of cancer screening programs. The aim of this study was to determine the survival rate of breast cancer and to investigate the related factors.

In the Cancer Registration Center of Hormozgan Health Department, 212 people with initial diagnosis of breast cancer had been registered. The Kaplan-Meyer method was used to determine the survival rate and determine the related risk factors using Cox proportional hazard regression model. For all tests, the error rate was considered 5%. Data analysis was performed by SPSS software (version 19).

The results showed that the five-year survival rate in patients with breast cancer is 80.2%. The risk of death is lower in people diagnosed in the early stages of cancer than in those diagnosed in the advanced stages (CI = 0.482-0.482: HR = 0.22). Risk of death in people with education of 8 classes and less was 0.267 (HR= 0.27, CI: 0.097-0.664) and in people with education of more than eight classes it was 0.254 (HR= 0.36, CI: 0.097-0.664).

According to the results of this study, implementation of screening program and early diagnosis of breast cancer in women with low levels of education, especially in the first level of the health system, is highly needed. In addition, prompt and timely referral of suspects is necessary.
