Moving Breast Cancer Therapy up a Notch.

Breast cancer is the second most common malignancy, worldwide. Treatment decisions are based on tumor stage, histological subtype, and receptor expression and include combinations of surgery, radiotherapy, and systemic treatment. These, together with earlier diagnosis, have resulted in increased survival.

The role of hypoxia inducible factor-1alpha in gynecological cancer.

Understanding the mechanisms of carcinogenesis and progression of gynecological tumors is important as these insights might lead to improved diagnostic tools for the pathologist, improved prediction of prognosis, response to therapy, and eventually better biology-based disease management, thereby improving prognosis and quality of life for the individual patient. Hypoxia is an important event in carcinogenesis because it renders a more aggressive phenotype with increased invasiveness and proliferation, formation of metastases and poorer survival. Although selecting patients with hypoxic tumors may therefore be clinically important, there is no consensus as to the method best suited for routine assessment of hypoxia.
