Capecitabine Plus Aromatase Inhibitor as First Line Therapy for Hormone Receptor Positive, HER2 Negative Metastatic Breast Cancer.

(1) Background: recent evidence suggests that long low-dose capecitabine regimens have a synergistic effect with endocrine therapy as aromatase inhibitors (AIs), and might increase overall survival for hormone-receptor-positive, HER2-negative, metastatic breast cancer compared to both treatments. We performed a retrospective study to confirm the efficacy and expand the safety data for capecitabine plus AI (a combination henceforth named XELIA) for this indication. (2) We conducted a single-center retrospective cohort study of 163 hormone receptor-positive metastatic breast cancer patients who received either the XELIA regimen, capecitabine, or an aromatase inhibitor (AI) as single agents in first-line treatment.

Ga-DTPA Anti-HER2 positron emission tomography/CT successfully predicts the overexpression of human epidermal growth factor receptor in lung metastases from breast cancer.

Molecular identification of a metastatic tumour without the inconvenience of a biopsy and the time required for pathological characterization is possible using molecular imaging. Here, we present the case of a patient with breast cancer in whom Ga-diethylenetriamine pentaacetic acid anti-human epidermal growth factor receptor 2 positron emission tomography-CT was successfully employed to characterize the expression of human epidermal growth factor receptor 2 in metastatic sites.

Recent progress in medical knowledge has indicated that both clinical and biological markers will determine the response to different medical treatments: age, gender and genetics will determine the success of treatment. Genetic variability in this respect is fundamental and determines efficiency and safety of drugs, as well as susceptibility and illness' development. Fortunately, personalized medicine now offers individually tailored treatment strategies for each patient's needs.

Thalidomide combined with neoadjuvant chemotherapy in angiosarcoma of the breast with complete pathologic response: case report and review of literature.

Background: Primary angiosarcoma of the breast is a rare malignancy.

Case Report: We report on a 41-year-old female patient who initially presented with locally advanced disease. Core biopsy showed angiosarcoma of the breast, grade 1, CD31-positive.

[Evaluation of breast cancer treatment at a tertiary-level institution with Popular Health Insurance in Mexico].

Background: In our country breast cancer represents a major health problem. Only 45% of all population has access to health services, the consequence is delay in diagnosis and treatment. In Mexico, 66% of all new cases of breast cancer are diagnosed in locally advanced stages.
