These difficulties are the biggest problems for patients with breast cancer and make it very important to know the issues related to this population. The state of Pará is the second largest territory in Brazil and has a profound inequality in health services. The amazon region presents several barriers, from the great distances from the places to the treatment centers to the few specialists in oncology. ![]() In the northern region of the country, BC is the second most incident form of tumor (19.21/100 thousand) following cervical cancer. However, due to difficulties in accessing health services, misdiagnosis or delay in diagnosis can occur. In Brazil, according to the Guidelines for the Early Detection of Breast Cancer, mammography is routinely recommended for women aged 50 to 69, once every two years. In Brazil, 15,403 deaths occurred due to BC in 2015 and it is estimated that 59,700 new cases occurred in the period 2018–2019, reaching an estimated risk rate of 56 cases per 100,000 women. The incidence and mortality rate related to BC continue to increase in both developing and developed countries. These findings can contribute to the development of regional strategies for early detection of breast cancer, reducing the incidence and mortality rates and increasing survival time.īreast cancer (BC) is the most prevalent malignancy and the leading cause of cancer death among women globally, accounting for 14.7% of all cancer-related deaths. Radiotherapy and hormone therapy were associated with increased survival. In the multivariate analysis, referral from the public health care system, advanced clinical stage, lymph node involvement and metastasis were associated with worse prognosis and lower survival rate. Mean survival time was 51.71 (± 17.22) months, with an estimated overall survival of 79.4%. Survival analysis involved the Kaplan-Meier statistical method and Cox regression analysis was performed. Sociodemographic, clinical/tumor, and treatment variables were obtained from the records at the Ophir Loyola Hospital. A retrospective hospital-based cohort study was conducted (2007–2013). ![]() The aim of this study was to analyze the five-year survival rate and prognostic factors in women treated for breast cancer in the city of Belém in northern Brazil. In Brazil, survival rates vary according to the region and few studies have been conducted on breast cancer survival in less developed areas, such as the Amazon region. Breast cancer is the most prevalent malignant neoplasm and the leading cause cancer of death among women globally.
