Materials And Methods: A survey was conducted and sent by email to 3,412 contacts in the Argentine Mastology Society (Sociedad Argentina de Mastología, or SAM) database, with responses from 396 physicians.

Impact of immunohistochemical profile changes following neoadjuvant therapy in the treatment of breast cancer.

Introduction: Currently, the indication for neoadjuvant chemotherapy is increasing in the treatment of breast cancer. Variability in the expression of biomarkers following neoadjuvant treatment has been observed, which could be accompanied by changes in the adjuvant treatment.

Objectives: The primary objective was to evaluate the variability of biomarkers prior to and following neoadjuvant therapy.

Bilateral breast carcinoma: clinical characteristics and its impact on survival.

The higher incidence of breast cancer, the improvements in diagnosis and treatment, together with the growing life expectancy have brought about an increase in the number of patients at risk for bilateral breast carcinoma. The aim of this study is to describe the characteristics of patients suffering from bilateral breast carcinoma who underwent surgery at the Breast Pathology Service of the Buenos Aires British Hospital and to analyze impact on survival. Between January 1970 and May 2007, 4,085 cases of breast carcinoma in 3,864 patients were treated at the Breast Diseases Division of the Buenos Aires British Hospital.
