卡铂术前不同分级盆腔动脉灌注化疗宫颈癌组织内铂离子浓度的对比研究

目的:对比术前超选择子宫动脉与髂内动脉前干灌注卡铂化疗宫颈癌癌组织内的铂离子浓度,为临床上选择合适的靶血管实施动脉化疗提供依据.方法:选择经病理检查证实为宫颈癌、且癌灶较大易于取材的患者14例,随机分为超选择子宫动脉灌注化疗组和髂内动脉前干灌注化疗组,以卡铂300 mg/m2一次性给药.在灌注后0、10、20分钟分别钳取宫颈癌组织,测定标本内铂离子浓度.结果:①峰值及曲线形态:两组癌组织内铂离子浓度的高峰值均出现在化疗结束后即刻,且随时间的延长而快速下降,呈一下降曲线.超选择子宫动脉灌注化疗组的峰值是251.00±119.39 ng/mg,髂内动脉前干灌注化疗组的峰值是186.73±110.66 ng/mg,差异无统计学意义(P>0.05).②浓度一时间曲线下面积(AUCo～20 min)值:超选择子宫动脉灌注化疗组化疗后0～20分钟的癌组织内铂离子浓度AUC0～20 min为3432.50±2099.94 ng.min/mg,髂内动脉前干灌注化疗组为2722.36±1474.34 ng.min/mg,差异无统计学意义(P>0.05).结论:超选择子宫动脉灌注与髂内动脉前干灌注化疗后癌组织内铂离子无论是峰浓度还是AUC0～20 min均无明显差别,但从减少动脉化疗并发症的角度,应根据宫颈癌的分期情况选择合适的靶血管管施动脉化疗.

Comparison of Platinum Concentration in Cervical Cancer Tissue through Different Levels of Pelvic Arteries Infusion Chemotherapy before Carboplatin Administration

Objective:To compare the platinum concentration in cervical cancer tissue via ultraselection uterine artery and anterior trunk of internal iliac artery infusion chemotherapy before carboplatin administration.Methods:Fourteen patients with advanced cervical cancer(large focus,easily taken) who had been proved by pathological examination were randomly divided into two groups:ultraselection uterine artery infusion group(group A,n=7) and anterior trunk of internal iliac artery infusion group(group B,n=7).Carbop...
