Radiation with the Strut-Adjusted Volume Implant (SAVI(tm)) controls cancer and could lessen the complications that accompany other types of brachytherapy.
The device concentrates dosage to the target tissue with minimum exposure of healthy surrounding tissue and organs.
"After almost two years, the patients showed that the treatment was well-tolerated without experiencing significant side effects. To date, the control rate of cancer is also very promising," said Catheryn Yashar, associate professor of radiation oncology at the UC San Diego School of Medicine and chief of breast and gynaecological radiation services at the Moores UCSD Cancer Center.
"This treatment allows us to provide internal radiation to the area without damaging the healthy tissue around the site, and minimizes radiation to a duration of only five days," explained Yashar.
"The traditional whole breast treatment usually takes approximately six weeks."
These findings are reported in the International Journal of Radiation Oncology, Biology and Physics.
