摘要
目的探索吉西他滨联合伽玛刀治疗局部晚期胰腺癌的最适剂量。方法采用"3+3"试验设计模式,患者接受伽玛刀和吉西他滨治疗,伽玛刀治疗计划52 Gy/13F,吉西他滨初始剂量700 mg/m2,每周1次,连续3周,剂量按照100 mg/m2依次递增,直至出现剂量限制性毒性反应。结果入组9例患者,700 mg/m2和800 mg/m2组完成治疗计划,当吉西他滨的剂量递增至900 mg/m2时出现剂量限制性的血液学毒性反应,试验中止。结论伽玛刀联合吉西他滨治疗局部晚期胰腺癌,吉西他滨的推荐剂量为800 mg/m2,每周1次,连续3周。
Objective To estimate the optimal dose of gemcitabine administered concurrently with gamma knife therapy in patients with locally advanced pancreatic cancer. Method “3＋3” model was measured in the study. Eligible patients had histologically confirmed pancreatic adenocarcinoma deemed locally unresectable. Patients received gamma knife therapy （52 Gy/13F） with concurrent infused weekly gemcitabine（dose escalated from 700 mg/m2 to 900 mg/m2 weekly） until dose-restricted toxicity. Results 9 patients were enrolled. Patients enrolled in gemcitabine 700 mg/m2 and 800 mg/m2 completed the plan.Ⅲ-Ⅳ degree hematology toxicity was seen in patients when gemcitabine dose escalated to 900 mg/m2. Conclutions The combination of gemcitabine and gamma knife therapy is well tolerated. The optimal dose of gemcitabine is 800 mg/m2 weekly.
