Special despatch of October 25 of www.xinhuanet.com Wuhan (reporter Li ChangZheng) In breast cancer radiotherapy, the ray will hurt organ and tissue around the neighbouring target region inevitably. Make heart make the mammary gland or wall of the chest shone by the capacity as well as a world difficult problem. The finding of Hubei tumour hospital, only narrow the area of wall ago the heart to the protection area of the heart, can base on the premise that tumour shines the dosage reduce the heart and receive radiation dosage effectively. This will be first proposition in the world " The area of wall ago the heart " Protect the protective area of heart of postoperative radiotherapy of milk as breast cancer. It has about coronary artery backbones and important branches which supplies the blood of heart that this area contains the front part of heart, coronary heart disease, atherosclerosis whom heart disease,etc. take place high to endanger the area, also accept the area where the high dosage shines at the time of the radiotherapy of breast cancer. The research of Hubei tumour hospital shows, the wall can make the heart shine the average dosage and reduce 20 under the international universal standard before protecting the heart, reduce patient's long-term heart death risk and invite 30 effectively. Studies have suggested, in the course of shining the mammary gland regionally, the left breast cancer patient close to the heart accepts heart disease caused by ray especially risk of coronary heart disease death are even higher than the breast cancer one 10 years or 20 years after radiotherapy Body. The radiotherapy centre director Hu DeSheng of tumour hospital in Hubei introduces, while the radiotherapy of breast cancer is planned to design, the doctor often protects the organ as jeopardizing of whole heart. But because the heart is relatively large in volume, make the mammary gland or wall of the chest is shone by the capacity and protects the heart well, it is very difficult, doctor and physical teacher often face the awkward choice while radiotherapy is planned to design. Hubei tumour hospital chooses 13 left breast cancer patients, we design 8 different accurate radiotherapy plans for each patient, the dosage shone in respectively different positions has got nearly 3 ten thousand data through monitoring the heart, analysing and researching these data carefully finds area this protects the area most effectively in the wall ago the heart.
