A new technique for radiotherapy said by researchers to be better that the one used , IMRT.

A New Technique May Prove A Better One

A sophisticated new radiotherapy technique has recently been found to possibly beat out the regular radiation methods used in treating mesothelioma patients.

The exciting new technique is called volumetric modulated arc therapy(VMAT) and is designed to deliver a well targeted radiation dose directly into the tumor. It gives the oncologist more control in giving a more targeted dose on the tumor itself and not the tissue surrounding the tumor. This spares the normal tissue around it. This also reduces the treatment time considerably. The VMAT technique also seems to be less affected by air cavities left behind after surgery that can cause issues.

At the Hiroshima University in Japan radiation oncologists did a study of 15 male mesothelioma patients. They were, following lung removing EPP surgery, treated with VMAT. They took several from a medium range of the age of 67. There were eight patients in earlier Stages I and II who were relatively free of involvement of the lymph nodes and seven who were in stage III.

During a year of follow-up after VMAT had been administered 55.7% had not experienced any new growth and 29% were found to be completely free of the disease. The best results were found in those patients with the most common form of the disease. Only three were effected by a serious side effect called pneumonitis.

One year ago a Swiss study that compared the two radiotherapies, IMRT and VMAT, found that the surrounding tissue and nearby organs got less radiation with the VMAT. And it showed to be more stable where the postsurgical air cavities were concerned. These cavities created in lung removal surgery cause problems with radiation therapy.

Because of the level of expertise needed to deliver this more precise and highly pin pointed treatment it is only available in the larger cancer facilities.
