一、前言腹腔内恶性肿瘤采用常规的全腹照射,由于局部脏器的放射耐受性以及机体对放射治疗的严重反应,限制了用射线进行高剂量、大面积的照射,因而活存下来的肿瘤细胞将较多达不到消灭或控制肿瘤细胞的效应。治疗效果往往也不理想。但是采用移动条全腹照射——条形野重复连续照射,在短期内使某一局部有较高的剂量,以达到控制肿瘤发展乃至杀死癌细胞,同时又能为病人所耐受。近年来,此种照射技术已逐渐推广,特别用于晚期卵巢癌、腹腔广泛累及之淋巴瘤和睾丸精原细胞瘤腹腔转移之患者,文献报告很多,并取得一定的疗效,而国内尚未见介绍。307医院肿瘤科自1979年1月开始 I. INTRODUCTION Abdominal malignant tumors use conventional full abdominal irradiation. Due to the radiation resistance of local organs and the severe response of the body to radiation therapy, the use of radiation for high-dose, large-area irradiation is limited, and thus survives. The tumor cells will not achieve the effect of eliminating or controlling the tumor cells. The treatment effect is often not ideal. However, the use of the mobile bar full-abdomen irradiation - strip field repeated continuous irradiation, in a short period of time to make a local high dose, in order to control the development of tumors and even kill the cancer cells, but also for patients tolerated. In recent years, this kind of irradiation technology has been gradually promoted, especially for patients with advanced ovarian cancer, lymphomas that are extensively involved in the abdominal cavity, and abdominal cavity metastases of testicular seminoma. There are many reports in the literature and they have achieved certain curative effects, but they have not yet been introduced in China. . 307 Hospital Oncology Division began in January 1979
