背景与目的 凡德他尼是一种多靶点口服的小分子抑制剂,可同时作用于血管内皮生长因子受体、表皮生长因子受体、RET酪氨酸激酶转染中的重排,本研究旨在探讨凡德他尼治疗晚期复治肺腺癌患者的疗效和副反应.方法 患者经过化疗和特罗凯治疗失败后,给予凡德他尼300 mg每日1次口服.结果 5例患者中,2例(40％)最佳疗效达疾病稳定( stable disease,SD),3例(60％)疗效均为疾病进展(progressive disease,PD).随访40个月,1例患者目前仍在随访中.中位无疾病进展时间( progression free survival,PFS)为2个月,平均总生存期(overall survival,OS)为22.6个月.出现副反应包括皮疹(n=2)、皮肤改变(n=2)、甲沟炎(n=2)、无症状的心电图QTc延长(n=2)、ST-T改变(n=1)、腹泻(n=1)、转氨酶增高(n=1).结论 凡德他尼治疗晚期复治肺腺癌患者中位PFS为2个月,平均OS为22.6个月,具有较好的安全性,结果同相关文献报道类似.%Background and objective Vandetanib is a once-daily oral multi-target inhibitor of vascular endothe-lial growth factor receptor, epidermal growth factor receptor, and rearranged during transfection (RET) tyrosine kinases. The current study aimed to evaluate the effect and safety of vandetanib administered in refractory advanced lung adenocarcinoma patients. Methods Five patients who accepted chemotherapy and Tarceva therapy as first- and second-line treatments received vandetanib (300 mg, oral, once daily). Results The effects are stable disease on two patients (40%) and progressive disease on three patients (60%). With a median follow-up of 36 months, one patient remained on follow-up. The median progression free survival (PFS) is 2 months, and the mean overall survival is 22.6 months. The adverse events include rash (n=2), skin change (n=2), paronychia (n=2), asymptomatic QTc prolongation (n=2), ST-T change (n=l), diarrhea (n=l), and increased trans-aminase (n=l). Conclusion There were lower incidences of severe side effects with vandetanib therapy in refractory advanced lung adenocarcinoma patients. The results of effect and safety of vandetanib are similar with the related reviewed articles.
