The study aims to evaluate the anti-tumor activity and toxicity of gemcitabine in patients with persistent or recurrent endometrial carcinoma.
Patients with advanced or recurrent carcinoma of the endometrium previously treated with one chemotherapy regimen were treated on a phase II trial conducted by the Gynecologic Oncology Group (GOG). Gemcitabine was administered as an intravenous infusion at a dose of 800 mg/m² over 30 min on days 1 and 8 every 21 days.
Twenty-four patients were entered by 11 GOG member institutions. One patient was ineligible due to wrong primary tumor. A total of ninety 21-day cycles of therapy were administered with 35% of patients receiving four or more cycles. All patients had been previously treated with a platinum-based regimen. One patient had a partial response (4%), nine had stable disease (39%), and twelve had increasing disease (52%). The median progression-free survival was 1.7 months. Treatment was generally well tolerated with only 22% of patients experiencing grade 3 or grade 4 hematologic toxicity. There was one treated-related death due to pulmonary toxicity.
Gemcitabine has minimal activity in the treatment of recurrent or persistent endometrial carcinoma at the dose and schedule tested.
本研究旨在评估吉西他滨治疗持续性或复发性子宫内膜癌患者的抗肿瘤活性和毒性。
妇科肿瘤学组(GOG)开展了一项 II 期临床试验,纳入了先前接受过一种化疗方案治疗的晚期或复发性子宫内膜癌患者。吉西他滨以 800mg/m² 的剂量静脉输注,持续 30 分钟,于第 1 天和第 8 天给药,每 21 天为一个周期。
11 个 GOG 成员机构共纳入了 24 例患者。由于原发肿瘤错误,1 例患者不符合入组条件。共进行了 90 个 21 天的治疗周期,35%的患者接受了 4 个或更多周期的治疗。所有患者均曾接受过基于铂类的治疗方案。1 例患者部分缓解(4%),9 例患者疾病稳定(39%),12 例患者疾病进展(52%)。中位无进展生存期为 1.7 个月。治疗总体耐受性良好,仅 22%的患者出现 3 级或 4 级血液学毒性。有 1 例治疗相关死亡,与肺毒性有关。
在该剂量和方案下,吉西他滨治疗复发性或持续性子宫内膜癌的活性有限。
