To evaluate the efficacy and toxicity of prolonged oral etoposide as single agent chemotherapy in patients with advanced or recurrent carcinoma of the cervix.
Between May 1991 and February 1993, 44 patients with advanced or recurrent carcinoma of the cervix were entered onto this study. Patients were eligible if they had received no more than two prior cytotoxic regimens. The initial dose of etoposide was 37.5 mg/m2 administered orally on a daily basis on days 1-21 of a 28-day cycle. Subsequent doses were unchanged, reduced, escalated, or omitted according to toxicity. Patients were evaluated for response and toxicity using standard Gynecologic Oncology Group criteria.
Forty-four patients were evaluable for response and toxicity. The overall response rate was 9.1% (2 CR, 2 PR). In patients with no prior chemotherapy the response rate was 4/25 compared to 0/19 for those who had prior therapy. The mean response duration was 2.7 months and the median survival from treatment for all patients was 7.7 months. The major toxicity was granulocytopenia, with 11% of patients having grade 3 or 4 toxicity. Gastrointestinal toxicity of some degree occurred in 11% of patients, and alopecia was universal.
Prolonged oral etoposide has limited activity in advanced or recurrent carcinoma of the cervix. Its use as palliative therapy for this disease is not indicated.
评估口服依托泊苷作为单一药物化疗对晚期或复发性宫颈癌患者的疗效及毒性。
1991年5月至1993年2月期间,44例晚期或复发性宫颈癌患者纳入本研究。若患者之前接受的细胞毒性治疗方案不超过两种,则符合入选条件。依托泊苷初始剂量为37.5mg/m²,在28天周期的第1 - 21天每日口服给药。后续剂量根据毒性情况保持不变、减少、增加或停用。使用标准的妇科肿瘤学组标准评估患者的反应和毒性。
44例患者可评估反应和毒性。总缓解率为9.1%(2例完全缓解,2例部分缓解)。未接受过化疗的患者缓解率为4/25,而接受过先前治疗的患者缓解率为0/19。平均缓解持续时间为2.7个月,所有患者从治疗开始的中位生存期为7.7个月。主要毒性为粒细胞减少,11%的患者出现3级或4级毒性。11%的患者出现一定程度的胃肠道毒性,脱发普遍存在。
口服依托泊苷对晚期或复发性宫颈癌的活性有限。不建议将其用于该疾病的姑息治疗。
