title: Cardiovascular complications associated with biological therapies for breast cancer.
abstract: BACKGROUND
  With increasing number of breast cancer survivors, treatment-associated toxicities are gaining importance because they may decrease quality of life and shorten expected survival. Biological treatment strategies are less toxic than conventional chemotherapy. However, practically all biological therapies for breast cancer induce cardiovascular complications. In the case of targeted therapies mechanisms of cardiotoxicity and strategies to manage cardiovascular disorders have not been completely defined.
  
  
  METHODS
  Articles were found by searching PubMed and abstract databases of several oncological meetings. This review summarizes the risks and mechanisms of cardiovascular complications associated with biological agents used in treatment of breast cancer.
  
  
  CONCLUSIONS
  Introduction of biological therapies has resulted in reduction of morbidity and mortality of breast cancer patients in recent years. However, all biological strategies bring a risk of cardiotoxicity and despite progress in the knowledge and management of cardiovascular complications there are still many unaswered questions.
