宫颈癌腹主动脉旁淋巴引流区预防性放疗的研究现状

Research status of prophylactic irradiation to para-aortic lymph nodes in cervical cancer

接受盆腔同步放化疗的宫颈癌患者腹主动脉旁淋巴结复发率高约10%,严重影响宫颈癌患者的预后。有研究提出对局部晚期宫颈癌的高危患者在盆腔放化疗的基础上行腹主动脉旁淋巴引流区预防性放疗。本文分析了腹主动脉旁淋巴引流区预防性放疗的疗效、适用人群、靶区上界、预防剂量及不良反应。

The recurrence rate of para-aortic lymph nodes in patients with cervical cancer un(.lergoing concurrent|)elvic chemoradiotherapy is approximately 10%,which seriously affects the prognosis of patients with cei^ical cancer.Some researchers suggest that high-risk patients with locally advanced cervical cancer undergo prophylactic irradiation to the para-aortic lymph nodes based on pelvic chemoradiotherapy.In this article,the clinical efficacy,the applicable population,the upper margin of the target volume,the preventive dose and the side effects of prophylactic irradiation to the para-aortic lymphatic nodes were analyzed.
