Methods Chemotherapy of 42 patients were randomly divided into group A (n = 20) with continuously constant arterial infusion, and group B (n = 22) with arterial chrono-modulated infusion. And the toxic effects and efficacy of two groups were compared. Results A significant difference was found in the toxic effects of digestive system between the two groups. The treatment response was similar in the two groups. Conclusions Intra-arterial chrono-chemotherapy may decrease the toxic effects and improve the life quality of these patients.

目的:观察CPT-11(艾力)时辰给药对鼻咽癌裸鼠的疗效、毒副反应以及细胞周期分布的变化,为CPT-11时辰化疗提供实验基础和临床应用参考。方法:统一光照条件下(光照时间7:00～19:00),黑暗时间(19:00～7:00)饲养3周、50只鼻咽癌移植瘤裸鼠...目的:观察CPT-11(艾力)时辰给药对鼻咽癌裸鼠的疗效、毒副反应以及细胞周期分布的变化,为CPT-11时辰化疗提供实验基础和临床应用参考。方法:统一光照条件下(光照时间7:00～19:00),黑暗时间(19:00～7:00)饲养3周、50只鼻咽癌移植瘤裸鼠模型分为给药组和对照组。给药组荷瘤小鼠在3、9、15、21HALO(Hours After Light Onset设光后小时)腹腔注射CPT-11 66mg/kg;15天后处死所有小鼠,检测各组小鼠的WBC、HB、PLT,然后剥离肿瘤计算各组抑瘤率,制成单个细胞悬液,固定,染色后流式细胞仪测DNA细胞周期含量;并取盲肠组织光镜下观察肠粘膜组织结构。结果:CPT-11对鼻咽癌移植瘤裸鼠有显著性疗效(P<0.01),其中15HALO,抑瘤率最大(P<0.05);而21HALO抑瘤率最小(P<0.05)。15HALO给药组WBC、HB、PLT数均高于其他各组(P<0.05),体重增加明显(P<0.05),光镜下粘膜损伤分级显著降低(P<0.05),21HALO给药组血象、体重增加最少,粘膜损伤分级较高(P<0.05)。9HALO要优于3HALO(P<0.05)。21HALO,3HALO细胞主要分布在G_2期(54.1100±17.3374053.0300±20.79316)。其中15HALO与21HALO差异最明显(P<0.01)。结论:CPT-11对鼻咽癌移植瘤裸鼠有明显的抑制作用且疗效及毒副作用呈现时辰节律变化(15HALO最优,21HALO最差),为CPT-11时辰化疗的临床应用提供了参考。展开更多
