摘要:
目的 探讨立体定向放射治疗(SBRT)序贯仑伐替尼治疗中晚期原发性肝癌的效果与安全性。 方法 选取2018年10月—2019年5月解放军总医院第五医学中心收治的18例中晚期原发性肝癌行SBRT联合仑伐替尼治疗患者。其中,BCLC B期4例,C期14例。给予计划靶区处方剂量48~55 Gy,中位值50 Gy,分6~10次,单次剂量中位值6(5~9)Gy/次。完成SBRT 1周后开始口服仑伐替尼治疗,用药中位时间为9.5(3.6~25.8)个月。治疗后前3个月,每月随访1次。治疗3个月后,每3个月随访1次。采用Kaplan-Meier法计算总生存、无进展生存、局部控制率,观察不良反应和并发症发生率。 结果 随访至2020年11月30日,共有8例患者死亡,其中3例因肝衰竭死亡,3例因肿瘤进展死亡,1例因胆囊穿孔死亡,1例因消化道出血死亡。治疗开始后3、6、9、12、18个月的总生存率分别为100%、94%、83%、72%、67%,无进展生存率分别为100%、67%、50%、22%、17%,局部控制率为100%、94%、94%、94%、94%,其中中位总生存期>18个月,中位无进展生存期为9个月。1例(6%)患者SBRT过程中出现3级不良反应,2例(11%)患者仑伐替尼治疗过程中出现3级不良反应,未发生致命性不良反应。 结论 初步证实SBRT序贯仑伐替尼是中晚期原发性肝癌有效、安全的治疗方法。 Abstract:Objective To investigate the efficacy and safety of sequential lenvatinib therapy after stereotactic body radiotherapy (SBRT) in the treatment of advanced primary liver cancer. Methods A total of 18 patients with advanced primary liver cancer who were admitted to The Fifth Medical Center of Chinese PLA General Hospital from October 2018 to May 2019 were enrolled, among whom there were 4 patients with BCLC stage B liver cancer and 14 patients with BCLC stage C liver cancer. The prescribed dose of planning target volume was 48-55 Gy (median 50 Gy) in 6-9 fractions, and the median of single dose was 6 (5-9) Gy per fraction. Oral administration of lenvatinib was given since 1 week after SBRT was finished, with a median medication time of 9.5 (3.6-25.8) months. Follow-up was performed once a month for the first 3 months after treatment and once every 3 months after 3 months of treatment. The Kaplan-Meier method was used to calculate overall survival (OS) rate, progression-free survival (PFS) rate, and local control (LC) rate, and the incidence rates of adverse reactions and complications were also observed. Results Up to the follow-up on November 30, 2020, a total of 8 patients died, among whom 3 died of liver failure, 3 died due to tumor progression, 1 died of perforation of gallbladder, and 1 died of gastrointestinal bleeding. At 3, 6, 9, 12, and 18 months of treatment, the OS rates were 100%, 94%, 83%, 72%, and 67%, respectively, the PFS rates were 100%, 67%, 50%, 22%, and 17%, respectively, and the LC rates were 100%, 94%, 94%, 94%, and 94%, respectively; the median OS time was > 18 months, and the median PFS time was 9 months. Of all patients, 1 (6%) had a grade 3 adverse reaction during SBRT and 2 (11%) experienced a grade 3 adverse reaction during lenvatinib treatment, and no fatal adverse reaction was observed. Conclusion It is preliminarily proved that sequential lenvatinib therapy after SBRT is an effective and safe treatment method for advanced primary liver cancer. -
