Blueberry extract can assist in radiotherapy for cervical cancer

2018-01-04

Cervical cancer is one of the common malignant tumors in women, and blueberries are a common fruit. A new study in the United States shows that combining blueberry extract with radiation therapy can improve the effectiveness of cervical cancer treatment.
Radiation therapy, which uses high-energy X-rays and gamma rays, is one of the commonly used treatments for cervical cancer. Radiation sensitizers are non-toxic chemicals that can make cancer cells more sensitive to radiation therapy, thereby enhancing their killing power against cancer cells. Previous studies have shown that there is a compound called resveratrol in red grapes that can be used as a radiation sensitizer in the treatment of prostate cancer.
Blueberries not only contain resveratrol, but also flavonoids with antioxidant, anti-inflammatory, and antibacterial properties. Researchers from institutions such as the University of Missouri at Columbia reported in the Hungarian journal Pathology and Oncology Research that they used blueberry extract as a radiation sensitizer and simulated clinical radiation therapy using human cervical cancer cell lines. The results showed that cancer cell lines receiving radiation therapy alone decreased by about 20%, while cancer cell lines receiving radiation therapy and using blueberry extract decreased by about 70%.
The researchers stated that the next step will be to conduct animal experiments to verify the above experimental results.
