[ Objective ] To grasp the level and the trend of medical exposure in the field of radiotherapy in Shanghai. [ Methods ] Based on the unified survey forms, the general status of a total of 29 hospitals performing radiotherapy was inquired, and the patient cases, prescribed doses, sex and age groups of patients in 2008 were further investigated among those hospitals. [ Results ] There were a total of 142 devices and 632 staffs engaged in radiotherapy in 2008 in Shanghai. The units of medical accelerators, X-knife and T-knife were 34, 9 and 2, respectively, and the numbers of physicians, medical physicists, technicians and nurses were 221,69, 197 and 145, respectively. The annual frequency of radiotherapy in 2008 was 1.26 per 1000 population, and it was as high as 1.64 per 1000 population of older than 40 years of age in Shanghai. Brain tumor, breast cancer, nasopharyngeal cancer and esophageal cancer were more common than other tumors undergoing radiotherapy, and the frequency of the male was 29% higher than that of the female. The total prescribed for target volume varied with different types of diseases, and the typical doses ranged from 20Gy to 70Gy. [ Conclusion ] In comparison with the frequency of radiotherapy in 1998, the frequency in 2008 increased in Shanghai. It is very important to strengthen the quality assurance of radiotherapy.
