[摘要] 目的 评价希罗达(Xeloda)单药治疗复发转移乳癌的近期疗效和不良反应。方法 希罗达单药2510mg/m2/天,分早晚2次口服,连续服用2周,休息1周为一周期。每个病人至少进行1个周期的治疗。结果 22例可评价疗效和不良反应的患者中,无CR 患者,PR 8例(36.4 %),总有效率36.4 %。SD 10例(45.5 %),PD 4例(18.2 %),临床获益患者(CR PR SD)18例(81.8 %)。蒽环类及紫杉类失败患者的有效率为30.0%~33.3%。常见不良反应为手足综合征、皮肤色素沉着、恶心、呕吐、厌食、疲劳,少数患者口炎、头晕、腹泻、胸闷。36.4%的患者有轻~中度贫血和白细胞下降,1例IV度骨髓抑制,个别患者胆红素和谷丙转氨酶轻度升高。结论 希罗达是治疗复发转移乳癌有效的药物,尤其是对蒽环类及紫杉类失败患者仍有效;治疗过程中患者耐受好,不良反应轻。

[A tract] Objective To evaluate re o e rate and adverse reaction of xeloda in the treatment of patients with rela ed metastatic breast cancer. Methods Xeloda was administered orally at a dose of 2510mg/m2/day divided into two dose for 14 days, followed by seven days’ rest and received 1 cycle of treatment at least. Results 22 patients were evaluable for re o e and toxicity, no complete re o e, 8 partial re o e , overall re o e of 36.4% ,10 stable disease(45.5 %), 4 progre ion disease(18.2 %), clinical benefit re o e(CR PR SD)of 81.8 %. Re o e rate was 30.0%~33.3% for the patients failed to chemotherapy regime containing both taxanes and/or an anthracycline. The frequent treatment-related adverse events are hand-foot syndrome, skin pigmentation, nausea, vomiting, anorexia and fatigue. the minority of patients occurred stomatitis, dizzine , diarrhoea and chest distre . There were patients of 36.4% with mild-morderat anaemia and leukopenia, and One occurred IV degree myelosu re ion.. Total bilirubin and ALAT elevation slightly occurred in the few of patients. Conclusion Xeloda is an effective drug in tne treatment of patients with rela ed metastatic breast cancer, and e esilly for patients failed to chemotherapy containing both taxanes and/or an anthracycline . Xeloda is well tolerated and reported mild adverse reactio .

蒽环类及紫杉类药物已广泛应用于乳癌临床,但由此失败或耐药的患者也日益增多,成为临床棘手问题。近年国外基础和临床研究表明,希罗达(Xeloda)虽属5-氟尿嘧啶类药物,但因其独特的肿瘤细胞内激活机制,对这些病人尚有较好疗[1-4],且全身毒性和骨髓抑制轻,是一个有前途的口服抗肿瘤药。
三0七医院受国家药品监督管理局(批件编号L-99024)指定,参加由广州中山医科大学附属肿瘤医院管忠震教授牵头组织的希罗达进口前临床验证研究,现将我们医院的验证材料及该药上市后治疗的2例病人的结果一并报告如下:
材料和方法
1.根据全国多中心研究方案的要求,选择病理证实乳腺癌,有可测量或可评价病灶,既往化疗失败的晚期病人入组研究。
2.希罗达单药2510mg/m2/天,分早晚2次餐后30分钟口服。连续服用2周,休息1周为一周期。每个病人至少进行1个周期的治疗。在治疗过程中,发现病情进展(PD)的病人随时退出试验。其他病人完成4个周期治疗,并需停药4周后,再次复查,确认疗效。
结 果
1.一般情况
从1999.12~2001.2入选女性乳癌患者23例。 1例患者接受希罗达治疗7天后,因依从性差,自动退出试验; 22例可评价疗效和不良反应。患者年龄36~68岁,中位年龄49岁。绝经前4例(18.2%),绝经后18例(81.8%)。K 70~90分,中位K 80分。术前临床分期I 期3例(13.6%),II 期13例(59.1%),III期5例(22.7%),IV期1例(4.5%)。术后无病间期0~20年,中位无病间期5年。所有患者均接受过辅助和/或解救化疗。
2.治疗效果
3例患者接受希罗达1周期治疗,1例2周期,皆因PD而退出试验;其余17例患者都接受4周
