[摘要] 目的 回顧性分析低劑量阿帕替尼治療晚期胃癌的臨床療效及不良反應(yīng)。 方法 收集51例應(yīng)用阿帕替尼治療三線及三線以上晚期胃癌患者,早餐后口服500 mg/d,觀察不良反應(yīng),定期復(fù)查評價療效,隨訪記錄生存時間。 結(jié)果 CR 患者0例,PR患者4例(6.67%),SD患者18例(35.29%),PD患者29例(56.87%),ORR為7.84%(4/51),DCR為43.13%(22/51)。單因素分析ECOG PS 評分0~1分患者有效率高于2分患者(P=0.001),合并手足綜合征、高血壓和蛋白尿,其治療有效率高于無相應(yīng)不良反應(yīng)者(均P<0.05),多因素Logistic回歸分析顯示:ECOG PS、合并手足綜合征、高血壓是療效獨立預(yù)測因素(均P<0.05)。患者mPFS 3.43個月(95% CI,3.19~3.68),mOS 4.36個月(95% CI 3.84~4.90),亞組分析顯示:DCR組mOS顯著長于PD組(6.32個月vs 2.90個月,P<0.05)。 結(jié)論 低劑量阿帕替尼(500 mg/d)治療三線及三線以上晚期胃癌療效確切,安全性良好,不良反應(yīng)可控。

[Abstract] Objective To retrospectively analyze the clinical efficacy and adverse reactions of low-dose apatinib in the treatment of advanced gastric cancer. Methods 51 patients with third-line or more advanced gastric cancer were treated with apatinib, oral 500mg/d after breakfast. Adverse reactions were observed, and the efficacy was evaluated regularly. The survival time was followed up. Results There was 0 patient with CR, 4 patients with pulmonary disease (6.67%), 18 patients with SD (35.29%) and 29 patients with PD (56.87%). The percentage of ORR and DCR was 7.84% (4/51) and 43.13%(22/51). Univariate analysis showed that the efficacy was higher in ECOG PS score 0-1 points patients than that in patients with more than 2 points (P=0.001). And the efficacy was higher in patients combined with hand-foot syndrome, hypertension and proteinuria in patients with no corresponding adverse reactions(all P<0.05). Multivariate Logistic regression analysis showed that ECOG PS, combined with hand-foot syndrome and hypertension were independent predictors of efficacy (all P<0.05). The mPFS and the mOS of patients was 3.43 months (95% CI, 3.19 to 3.68) and 4.36 months(95% CI 3.84 to 4.90). Subgroup analysis showed that mOS was significantly longer in the DCR group than that in the PD group (6.32 months vs 2.90 months, P<0.05). Conclusion Low-dose apafitinib (500 mg/d) is effective in the treatment of third-line or more advanced gastric cancer, with good safety and controllable adverse reactions.

胃癌在我國是重點防控的惡性腫瘤之一,造成沉重的醫(yī)療衛(wèi)生負(fù)擔(dān)[1]。2012年中國胃癌的新增病例和死亡人數(shù)均占全球的約42%[2-3],胃癌占我國惡性腫瘤發(fā)病率第二位,惡性腫瘤死亡率第3位[4]。胃癌發(fā)病年齡以40~60歲最常見,男女比例為2.67:1,確診時多已進(jìn)展為晚期胃癌[5]。阿帕替尼(Apatinib,YN968D1),是我國首個完全自主研發(fā)的1.1類抗腫瘤新藥,也是全球第一個在晚期胃癌患者中被證實為安全有效的小分子血管內(nèi)皮細(xì)胞生長因子受體2(vascularendothelial growth factor receptor 2,VEGFR-2)酪氨酸激酶抑制劑[6]。目前阿帕替尼推薦劑量為850 mg/d,但對美國東部腫瘤協(xié)作組(eastern cooperative oncology group,ECOG)體力狀況(performance status,PS)評分>2分、多線化療以后、胃內(nèi)原發(fā)癌灶沒有切除、骨髓功能儲備差、年老體弱等患者,直接應(yīng)用治療劑量850 mg/d多數(shù)患者不能耐受,為了確?;颊叩陌踩院鸵缽男裕梢赃m當(dāng)降低治療劑量[7],本研究收集的晚期胃癌患者以阿帕替尼500 mg/d為治療劑量,回顧性分析阿帕替尼治療療效及安全性。
