兆伏级放射治疗对各种情况的鳞状上皮细胞食道癌有良效。阿尔伯塔大学放射学教授皮尔逊在美国癌症学会在旧金山举行的全国放射肿瘤学会议上说,对食道下段进行照射,放射治疗比手术优越,因可增加早期存活机会并保护正常的贲门和胃部。如果癌瘤在食道中段,在增加短期和长期存活机会和保护正常的胃方面,放射治疗的效果也比较好。如果癌瘤位于食道上段,放射治疗的优越性在于有较好的存活机会和保护正常的喉部。皮尔逊对近四十年来爱丁堡医学中心食道癌的治疗进行了研究。这个时期对这种癌症的治疗是徘徊在手术与放射治疗之间。从 Mega-volume radiation therapy has good effect on squamous cell esophageal cancer in various conditions. University of Alberta professor of radiology Pearson said at the American Cancer Society’s National Conference on Radiation Oncology in San Francisco that radiation therapy is superior to surgery in the lower esophagus, because it can increase early chances of survival and protect the normal heart and stomach. unit. If the cancer is in the middle of the esophagus, radiotherapy is also effective in increasing short-term and long-term survival and protecting the normal stomach. If the cancer is located in the upper esophagus, the advantage of radiation therapy is better survival and protection of the normal larynx. Pearson has studied the treatment of esophageal cancer in Edinburgh Medical Center for nearly four decades. The treatment of this cancer during this period is between surgery and radiation therapy.
