There are few reports on the pharmacokinetics of paclitaxel combined with carboplatin or on the dose schedule of carboplatin in combination use during hemodialysis in patients with ovarian cancer.
A 40-year-old woman with chronic renal failure on hemodialysis who had FIGO stage III ovarian cancer was treated with debulking surgery and carboplatin/paclitaxel combination chemotherapy. Paclitaxal was administered at 150 mg/m(2) as a 3-h intravenous infusion followed by a 30-min infusion of carboplatin on a nondialysis day. The carboplatin dose was chosen to produce a target area under the concentration/time curve (AUC) of 5.0 microg-min/ml according to the Calvert formula. The pharmacokinetic study showed that the AUCs of free platinum and paclitaxel were 4.43 microg-min/ml and 15.9 microg-h/ml, respectively. Dosing of carboplatin based on the AUC produced an acceptable degree of thrombocytopenia and neutropenia. After the completion of five cycles of the combination chemotherapy, the tumor showed complete response, and the patient remained disease free for 8 months.
Paclitaxel and carboplatin combination chemotherapy can be given to patients undergoing hemodialysis, with dialysis performed 16 h after the administration and with a dose adjustment of carboplatin to reach a target AUC. In these conditions, tumor response can be obtained.
关于卵巢癌患者血液透析期间紫杉醇联合卡铂的药代动力学或卡铂联合使用剂量方案的报道较少。
一名40岁接受血液透析的慢性肾衰竭女性,患有国际妇产科联盟(FIGO)III期卵巢癌,接受了肿瘤细胞减灭术及卡铂/紫杉醇联合化疗。在非透析日,紫杉醇以150mg/m²的剂量静脉输注3小时,随后输注卡铂30分钟。根据卡尔弗特公式选择卡铂剂量,以使浓度/时间曲线下面积(AUC)达到5.0μg·min/ml的目标值。药代动力学研究表明,游离铂和紫杉醇的AUC分别为4.43μg·min/ml和15.9μg·h/ml。基于AUC给药的卡铂产生了可接受程度的血小板减少和中性粒细胞减少。在完成五个周期的联合化疗后,肿瘤显示完全缓解,患者无病生存8个月。
对于接受血液透析的患者,可以给予紫杉醇和卡铂联合化疗,在给药后16小时进行透析,并调整卡铂剂量以达到目标AUC。在这些条件下,可以获得肿瘤反应。
