Pentoxifylline and vitamin E for treatment or prevention of radiation-induced fibrosis in patients with breast cancer.

Radiation therapy (RT) plays an important role in the management of breast cancer. Radiation-induced fibrosis is a side effect of radiation therapy and may occur in up to 13% of the cases in patients (Radiother Oncol, 2009;90:80), fortunately usually is modest/localized and not associated with marked symptoms. However, occasionally, fibrosis can be moderate-to-severe, and cause clinically-meaningful symptoms. The current review summarizes the use of pentoxifylline and vitamin E of treatment or prevention of radiation-induced fibrosis in breast cancer patients. Even though data are limited, this regimen may reduce RT-associated toxicity.
