-
摘要:
目的 开发能预测骨肉瘤化疗耐药的评分系统,指导医生更好地选择合适的治疗方案。 方法 2014年1月至2017年12月在昆明医科大学第三附属医院119例经病理诊断为骨肉瘤并行新辅助化疗的患者纳入研究,收集其一般情况及血液指标、初诊表现、治疗模式、治疗疗效以及生存时间。 结果 (1)根据RECIST 1.1进行疗效评,119例患者78人评估为稳定(SD组),41评估为进(PD组);且转移对化疗疗效无明显影响,P > 0.05;(2)两组间进行比较结果发现分期、初诊时间、原发灶大小、化疗周期、化疗药物种类、化疗前淋巴细胞/白细胞比值、化疗前中性粒细胞/淋巴细胞比值、化疗前白蛋白、化疗前谷草转氨酶、化疗前尿酸、化疗后尿素氮、化疗后尿酸、化疗前低密度脂蛋白,差异有统计学意义(P < 0.05),且根据ROC曲线最佳截断值得出:分期≥III期、化疗周期≤2周期、化疗药物种类≤3种、化疗前淋巴细胞/白细胞≤0.32、化疗前中性粒细胞/淋巴细胞≤1.98、化疗前白蛋白≥48 g/L、化疗后尿素氮≥4.22 mmol/L、化疗后尿酸≥305 umol/L、TGF-β总得分≥8.5分是骨肉瘤患者发生化疗耐药的危险因素;(3)患者具有一次危险因素记为1分,0~3分列为1组;4~6分列为2组;7~9分列为3组。将1组,2组,3组三个组疗效进行比较,差异有统计学意义,P < 0.05。 结论 分期、化疗周期、化疗药物数量、化疗前淋巴细胞/白细胞、化疗前中性粒细胞/淋巴细胞、化疗前白蛋白、化疗后尿素氮、化疗后尿酸、TGF-β总得分是骨肉瘤化疗耐药相关临床因素,本研究为尽早评估出化疗耐药的患者的同时评估可能发生化疗耐药的程度提供了充足的理论依据。 Abstract:Objective The purpose of this study was to develop a scoring system to predict chemotherapy resistance of osteosarcoma, which could guide doctors to better choose the appropriate treatment. Methods 119 cases of osteosarcoma with neoadjuvant chemotherapy were diagnosed by pathology at the Third Affiliated Hospital of Kunming Medical University between January 2013 and December 2017 and the covariates including general situation, blood indexes, initial diagnosis, treatment mode, therapeutic effect and survival were analyzed. Results According to RECIST 1.1, 78 of 119 patients were evaluated as stable disease(SD group)and 41 as progressive disease(PD group); There was signifcant difference in staging, initial visit time, initial tumor size, neoadjuvant chemotherapy cycle, types of chemotherapy drugs, lymphocyte/leukocyte prechemotherapy, neutrophils/lymphocytes prechemotherapy, albumin prechemotherapy, ALP prechemotherapy, Uric acid prechemotherapy, BUN after the chemotherapy, uric acid after the chemotherapy, LDL prechemotherapy, TGF-β score, TCNR between SD group and PD group(P < 0.05). Metastasis had no significant effect on the efficacy of chemotherapy. According to the ROC curve, the best cut-off value showed staging≥III, neoadjuvant chemotherapy cycle≤3, Lymphocyte/leukocyte prechemotherapy≤0.32, neutrophils/lymphocytes ≤1.98, albumin prechemotherapy, ≥48 g/L, BUN after the chemotherapy≥4.22 mmol/L, uric acid after the chemotherapy≥305 umol/L. TGF-β score≥8.5 was the risk factor for chemotherapy resistance in patients with osteosarcoma.3. Patients with one risk factors add 1, and 0-3 were classified as group 1. 4-6 were listed as group 2; 7-9 were listed as group 3 and there was no statistically significant difference between the three groups. Conclusion This study explored the clinical factors related to chemotherapy resistance of osteosarcoma. -
