摘要
目的研究卵巢癌患者化疗后,紫杉醇(PTX)血药浓度与疗效及不良反应的相关性。方法75例卵巢癌患者接受PT方案(紫杉醇+卡铂)一线化疗。于每周期PTX静脉输注开始后(24±6)h采集静脉血2次,采用胶乳免疫比浊法检测PTX浓度。根据PTX血药浓度的平均值,将75例患者分为≤25 h组、(26~30)h组和≥31 h组,回顾性分析PTX血药浓度与疗效及与不良反应间的相关性。结果≤25 h组、(26~30)h组、≥31 h组PTX血药浓度分别为(22.54±2.04)h、(28.62±1.87)h、(33.01±2.84)h,差异有统计学意义(P<0.05)。随着PTX血药浓度的升高,化疗的不良反应发生率增多,程度加强(P<0.05)。(26~30)h组的有效率(31.25%)高于≤25 h组(20%)(P=0.02),与≥31 h组有效率(33.33%)相比差异无统计学意义(P=0.96)。结论卵巢癌采用紫杉醇PTX血药浓度在(26~30)h的患者疗效好,且不良反应稍低。
Objective To investigate the relationship between plasma concentration of paclitaxel（PTX） and the efficacy as well as toxic and side effects in the patients with ovarian cancer. Methods Seventy-five patients with ovarian cancer accepted PT（paclitaxel＋carboplatin） chemotherapy regimen as their first line treatment. The blood samples were taken twice at（24±6）h after continuous infusion of paclitaxel in each cycle and the plasma concentration of paclitaxel was detected by latex immuno-turdidimetry. The patients were randomly assigned into three groups according to the average plasma concentration of paclitaxel： group 1（plasma concentration paclitaxel≤25h）, group 2（26-30h） and group 3（≥31h）. The relationship between the drug plasma concentration, therapeutic efficacy and adverse reactions in different paclitaxel plasma concentration was analyzed retrospectively. Results The average plasma concentrations of paclitaxel of the three groups were（22.54±2.04）h,（28.62±1.87）h, 33.01±2.84）h, respectively（P〈0.05）. The incidence and extent of adverse reactions were significantly higher and stronger with the increasing plasma concentration of paclitaxel. The therapeutic efficacy of group 2（26-30）h was 31.25% which was better than that（20%） of group 1（≤25h）（P=0.02）, but had no significant difference with that（33.33%） of group 3（≥31h）（P=0.96）. Conclusion The ovarian cancer patients treated with paclitaxel-based chemotherapy with an average plasma concentration of paclitaxel between 26-30 h have a higher curative effect and lower toxic side effect.
