Objective: This study aimed to evaluate the association of axillary lymph node ratio (LNR) and number of positive lymph nodes (pN) with the risk of breast cancer recurrence and death.
Materials And Methods: A retrospective cohort study of node-positive stage II and III breast cancer patients diagnosed and treated between 2008 and 2009 at the Brazilian National Cancer Institute (INCA), Brazil. Overall and disease-free survival curves for number of positive lymph nodes (pN) and lymph node ratio (LNR) risk groups were constructed using the Kaplan-Meier method and compared by the log-rank test.
Objective: To analyze the association between four biomarkers and overall survival in patients with breast cancer (BC).
Methodology: This cohort study had a sample of 2374 women over the age of 18, diagnosed and treated in a single reference center for BC in Brazil, during the year 2008-2009. The following pretreatment indices were analyzed: neutrophil-lymphocyte ratio (NLR), a derived neutrophil-lymphocyte ratio (dNLR), absolute neutrophil count (ANC) and platelet-lymphocyte ratio (PLR).
Purpose. To assess the quality of life (QOL) as a predictor of volume reduction in women undergoing complex physical therapy (CPT) for lymphoedema following breast cancer. Methods.

Aim: Analyze the determinants of advanced staging in Brazilian women with breast cancer.
Methods: Crosssectional study, including women diagnosed with breast cancer in Brazil, between 2000 and 2009.
Background: Post-mastectomy pain syndrome is defined as a chronic pain that persists beyond the normal healing time of 3 months. It is considered a neuropathic condition that arises after surgery for breast cancer.
Aim: To evaluate the incidence and risk factors of pain syndromes in patients undergoing surgical treatment of breast cancer in the National Cancer Institute.
