New approach to cancer treatment ‘could enhance radiotherapy’

3rd August 2009

A new approach to cancer treatment could radically increase the effectiveness of radiotherapy, a study has revealed.

Cancer Research UK says that its scientists have identified a new methodology regarding cancer treatment that improves the stability of blood vessels in tumours.

Scientists from the Cancer Research UK-MRC Gray Institute for Radiation Oncology and Biology at the University of Oxford treated mice with drugs that were found to improve the stability of the tumour blood vessels.

These vessels are usually badly developed as a result of the cancer.

It was discovered that by improving the blood vessels, a greater concentration of oxygen was available inside the tumour, boosting its sensitivity to radiotherapy.

Professor Gillies McKenna, director of the institute, said: “We are very excited to have uncovered this brand new approach to cancer treatment – where the drugs prime the cancer cells for radiotherapy.”

Dr Lesley Walker, Cancer Research UK’s director of cancer information, said: “Boosting the effects of radiotherapy and chemotherapy are very exciting developments.”
