Production and approval of trastuzumab (Herceptin®) for the treatment of metastatic breast cancer (MBC) was a millstone in antibody-based targeted therapy in the cancer treatment. However, despite the early success in the clinical trials, trastuzumab failed to appreciate the initial attraction due to development of resistance to the drug. The majority of patients who benefit from the drug...

Objective(s): Drug-induced atrial fibrillation (AF) is considered an adverse effect of chemotherapeutic drugs. AF is a crucial risk factor for stroke, heart failure, myocardial infarction, and mortality. Pulmonary veins (PVs) are considered triggers inducing AF, and the sinoatrial node (SAN) may modulate PV activity and participate in AF genesis. AF was associated with...

Background: Trastuzumab in combination with chemotherapy has long been established as a standard treatment for HER2-positive patients in early stage breast cancer (BC). The present study aimed at assessing the effectiveness of trastuzumab adjuvant therapy in early stage BC in overall survival (OS) and disease-free survival (DFS).    Methods: A systematic review and meta-analysis was ...

Trastuzumab is a specific monoclonal antibody used for therapeutic of the human epidermal growth factor receptor 2 (HER-2) -positive metastatic breast cancer. But, resistance to trastuzumab is a major obstacle in clinical efficiency.  During the past years, several studies have been done to find the mechanisms contributing to trastuzumab resistance. Previous studies have highlighted that bone m...

background : in developed or developing countries, the most common cancer in women is breast cancer with a pick in 40–50 years in asia. herein, we compared the association between ihc with fish in her2-positive breast cancer patients and affection of trastuzumab on disease free survival and overall survival (os). subjects and methods: immunohistochemical (ihc) analysis of hormone receptors and ...
