1992年1月至1993年3月我科在我省首次开展对96例恶性肿瘤实施高剂量率近距离遥控后装放射治疗。其中宫颈癌38例,鼻咽癌27例,鼻腔癌15例、食管癌6例、恶性纤维组织细胞瘤4例、喉癌2例、口底癌2例、舌癌2例,均为病理学证实。治疗方法采用WD-HDR18型现代近距离控遥后装机高剂量率放射治疗,配合远距离Co-60γ射线外放射。施行腔、管、道对内放射和瘤体插植、敷贴。本方法的临床应用能弥补外放射及低剂量率近距离治疗的弊端,尤其失去手术和外放射机会实体瘤和残留肿瘤增加了新的治疗手段。放射损伤轻,近期疗效满意,远期疗效仍在观察中。
From January 1992 to March 1993, our department conducted the first time in our province to carry out high-dose rate remote-controlled remote control of 96 cases of malignant tumors. There were 38 cases of cervical cancer, 27 cases of nasopharyngeal carcinoma, 15 cases of nasal cancer, 6 cases of esophageal cancer, 4 cases of malignant fibrous histocytoma, 2 cases of laryngeal carcinoma, 2 cases of carcinoma of the floor, 2 cases of tongue cancer. Confirmed. The treatment method used the WD-HDR18 type modern near-distance controlled remote post-installation high-dose-rate radiotherapy combined with long-distance Co-60 gamma ray external radiation. Cavity, tube, and channel internal radiation and tumor implantation and application were performed. The clinical application of this method can make up for the shortcomings of external radiation and low-dose-rate brachytherapy, especially the loss of surgical and external radiation opportunities for solid tumors and residual tumors adds new treatments. The radiation damage is light and the short-term efficacy is satisfactory. The long-term efficacy is still under observation.
