Radiation therapy for pancreatic carcinoma / 中华肝胆外科杂志

Surgery is the treatment of choice for pancreatic carcinoma.However,only 20％ of patients are eligible for surgery,and local control of disease and survival are not good.Although non-surgical treatments result in poor outcome,chemotherapy has been shown to be an effective treatment.The role of irradiation has not been well-established.Modern irradiation technology has shown promising results but there is still lack of strong prospective research evidence to support its widespread use.Irradiation brings along problems which need to be resolved,including target motion,definition of irradiation target,optimal fractionation,total treatment time and the treatment sequence of surgery,chemotherapy and radiation therapy.
