宫颈癌放射治疗

The radiotherapy of cervical cancer

宫颈癌是常见女性生殖道恶性肿瘤,主要治疗手段为手术治疗和放射治疗。其中放射治疗分为根治性放疗、辅助放疗与姑息性放疗。对于早期宫颈癌,根治性放疗可取得与手术相类似的生存率,后装治疗能提高总生存率。对于局部晚期宫颈癌,根治性放疗较手术治疗并发症少、生活质量高,可作为FIGO分期IIB期以上的局部晚期宫颈癌病例的首选。对于分期手术后有复发中高危因素的患者,可行辅助放疗,能提高生存率。对于晚期或复发的宫颈癌患者,可行姑息性放疗进行局部病灶控制。对于阴道大出血的患者,后装治疗有理想的止血效果。

Cervical cancer is the common cancer in female genital tract. Primary treatment is surgery or radiotherapy including radical radiotherapy, adjuvant radiotherapy and palliative radiotherapy. Radical radiotherapy can get a same survival rate as a surgery for early stage cervical cancer and brachytherapy as an important part of radical radiotherapy can improve overall survival. For locally advanced cervical cancer, radical radiotherapy can achieve a curative effect with less complications and higher quality of life compared with surgery. Radical radiotherapy is the first choice for stage IIb or more advanced patients. For patients with high risk factors of recurrence after staging-surgery, the survival rate can be improved by adjuvant radiotherapy. For patients with recurrent cervical cancer, palliative radiotherapy is feasible for the control of local lesions. For vaginal bleeding patients, brachytherapy has an ideal hemostatic effect. Radiotherapy is an important treatment for cervical cancer and is a preferred treatment for locally advanced patients.
