小剂量阿帕替尼联合化疗治疗晚期恶性肿瘤的临床研究

Clinical study of the combination of low-dose apatinib and lowintensity chemotherapy in the treatment of advanced malignant cancer

目的探讨小剂量阿帕替尼联合化疗在经过三线或以上化疗的晚期肿瘤的治疗中的疗效及安全性。方法回顾我院2015年7月~2017年7月经过三线或以上化疗后仍在进展的晚期肿瘤患者47例,包括胃癌、肺癌、肝癌、鼻咽癌、卵巢癌、乳腺癌及结直肠癌,随机分成两组,对照组使用常规剂量阿帕替尼0.75g一次/d,实验组使用小剂量阿帕替尼0.25g一次/d,联合低强度化疗,对疗效及不良反应进行分析。结果两组均无CR病例,对照组无PR病例,SD 9例,PD 16例,实验组PR 4例,SD 6例,PD 12例,对照组组与实验组的ORR和DCR分别是(0 vs 18.2%)、(36.0%vs 45.5%),不良反应主要是乏力、纳差、口腔炎、声嘶、手足综合征、骨髓抑制、蛋白尿及高血压,两组耐受性均良好。结论小剂量阿帕替尼联合低强度化疗对于经过多线治疗的晚期肿瘤患者,客观有效率高,使用方便,费用低,不良反应可控,是经过多线抗肿瘤治疗的晚期肿瘤患者一个合理的选择。

Objective To investigate the efficacy and safety of the combination of low-dose apatinib and lowintensity chemotherapy in the treatment of advanced malignant cancer after three or more line of chemotherapy. Methods From July 2015 to July 2017, 47 advanced cancer patients who still progresses after three or more line of chemotherapy in our hospital, including gastric cancer, lung cancer, liver cancer, nasopharyngeal carcinoma, ovarian cancer, breast cancer and colorectal cancer, were retrospectively analyzed and randomly divided into two groups. The control group was treated with conventional dose of apatinib, 0.75 g once a day, the experimental group was treated with low-dose of apatinib, 0.25 g once a day, combined with low intensity chemotherapy. The efficacy and adverse reactions of the two groups were analyzed. Results There were no CR cases in both groups. There were no PR cases, SD 9 cases and PD 16 cases in control group, PR 4 cases, SD 6 cases and PD 12 cases in experimental group. ORR and DCR in control group and experimental group were（0 vs. 18.2%） and（36.0% vs. 45.5%） respectively. Adverse reactions were mainly fatigue, decreased appetite, stomatitis, hoarseness, hand-foot syndrome, myelosuppression, proteinuria and hypertension. Both groups were well tolerated. Conclusion Low-dose apatinib combined with lowintensity chemotherapy is a reasonable choice for advanced cancer patients who have undergone multi-line therapy because of its high objective efficiency, convenient use, low cost and controllable adverse reactions.
