回顾了腔内治疗宫颈癌的历史,提出在后装腔内治疗中,应尽量采用分割方式治疗。分割方式腔内治疗的好处是可使正常组织在分割照射期间得到修复;另外由于在分割期间肿瘤不断消退,更有效地发挥了剂量分布与距离平方成反比的特点,有利于控制肿瘤,保护正常组织。作者特别强调在腔内治疗中要将治疗个别化;对局部Ⅱ期以上病变采用分割治疗方式;在由于肿瘤造成盆腔内解剖结构不对称时,不要过多依赖A点来计算剂量;在设计施用器时要特别注意避免直肠和膀胱的损伤。
The history of endocervical treatment of cervical cancer was reviewed and it was suggested that segmental treatment should be used as far as possible in posterior cavity endovascular treatment. The advantage of segmented intracavity therapy is that normal tissue can be repaired during segmentation; in addition, because the tumor continuously subsides during segmentation, the dose distribution is inversely proportional to the square of the distance, which is beneficial to tumor control and protection. organization. The authors emphasized in particular that the treatment should be individualized in endoluminal treatment; segmental treatment should be adopted for the local phase II or above lesions; when the pelvic anatomy is asymmetric due to tumor, do not rely too much on point A to calculate the dose; Special care should be taken to avoid damage to the rectum and bladder.
