单纯经尿道切除(TUR)治疗表浅性膀胱癌复发率较高。针对TUR有发生残余癌及术中肿瘤细胞种植、扩散的问题,在TUR结束时,立即进行体外放疗,减少了术后癌的复发率。 1984～1991年TUR治疗初发的原发膀胱癌72例,其中56例为表浅性移行上皮癌(77.8%),对其中46例低分级(G_1、G_2)癌(63.9%),电切后立即行放疗。方法:术前先去放疗室确定膀胱区照射区域,在TUR时,对癌肿周1cm区域行充分电切,TUR结束后立即送放疗室进行膀胱区前后两个部位的体外照射,照射量1次5Gy,以后每周放疗2次,共4次,总量20Gy。
Transurethral resection (TUR) treatment of superficial bladder cancer recurrence rate is higher. In response to the occurrence of residual cancer in TUR and the implantation and spread of intraoperative tumor cells, in vitro radiotherapy was performed immediately after the end of TUR, reducing the recurrence rate of postoperative cancer. From 1984 to 1991, 72 cases of primary bladder cancer were initially treated with TUR, of which 56 cases were superficial transitional epithelial carcinoma (77.8%), 46 of them were low-grade (G 1 and G 2 ) cancers (63.9%). Immediately after radiotherapy. Methods: Before the operation, the radiotherapy room was used to determine the irradiation area in the bladder region. During the TUR, a full electrotomy was performed on the 1cm area of the tumor. After the TUR, the radiotherapy room was immediately sent to the outside of the bladder area for external irradiation. 5Gy, 2 times a week after radiotherapy, a total of 4 times, the total 20Gy.
