观察非小细胞肺癌患者循环肿瘤细胞在治疗中的动态变化及与预后相关性的前瞻性研究(1)
【摘要】 目的:探究非小细胞肺癌患者循环肿瘤细胞在治疗中的动态变化及相关的预后前瞻性研究。方法:选取本院2014年1月-2017年1月收治的200例晚期非小细胞肺癌患者,在给予治疗后,采集患者一线、二线化疗前后外周血,采用多重mRNA原位分析法测定患者治疗前后循环肿瘤细胞(CTC)计数,采用相关性分析软件对CTC细胞数变化与无进展生存期(progression-free survival,PFS)、客观缓解率(objective response rate,ORR)、总生存期(overall survival,OS)的关系进行分析。结果:200例患者治疗后CTC细胞阳性率显著低于治疗前,差异有统计学意义(P<0.05);同时,患者的CTC表达同OS与ORR均呈负相关(P<0.05)。结论:非小细胞肺癌患者采用一线、二线化疗时通过捕捉检测患者外周血中痕量存在的CTC,采用多重mRNA原位分析法动态监测CTC细胞数,有助于评估临床疗效,且与预后具有相关性,有助于指导临床治疗,可进一步分析研究。

【Abstract】 Objective:To investigate the dynamic changes of circulating tumor cells in patients with non-small cell lung cancer (NSCLC) and to investigate the prognosis of the changes.Method:200 patients with advanced non-small cell lung cancer treated in our hospital from January 2014 to January 2017 were selected.Blood samples were collected before and after the first and second chemotherapy.Determination of circulating tumor cells (CTC) count before and after treatment by multiple mRNA in situ analysis,and correlation analysis software was used to analyze the relationship between CTC cell number and progression-free survival(PFS),objective response rate(ORR),overall survival(OS).Result:The positive rate of CTC cells in 200 patients after treatment was significantly lower than that before treatment(P<0.05).Meanwhile,the expression of CTC was negatively correlated with OS and ORR(P<0.05).Conclusion:Patients with non-small cell lung cancer use the first line and second line chemotherapy to detect the presence of trace CTC in the peripheral blood of the patients,the multiple mRNA in situ analysis is used to dynamically monitor the number of CTC cells,it is helpful to evaluate the clinical effect and be related to the prognosis,which helps to guide the clinical treatment and can be further analyzed.

肺癌是一種临床上常见的恶性肿瘤,近年来随着各种环境因素以及我国人均寿命的延长,我国肺癌发生率也随之上升。其中非小细胞肺癌(NSCLC)占到了肺癌患者的85%左右[1],并且大多数处于晚期,目前晚期非小细胞肺癌患者死亡率处于我国恶性肿瘤首位,在治疗上,传统的治疗方式主要是化疗[2],目前随着分子生物技术及药物的发展,出现了靶向治疗与免疫治疗,使晚期肺癌患者的生存期明显延长,在肺癌治疗中,一般采用影像学进行评价,但存在滞后性,并且无法进行生物学特点的检测。循环肿瘤细胞(CTC)泛指存在于人体外周血内各类肿瘤细胞的总称,此类细胞多由于自发性或诊疗性操作使其在原有实体病灶中脱落,而后进入人体外周血中,多数自行凋亡,仅少数进展为转移灶,对患者生命安全存在严重威胁。CTC能够准确反映患者的肿瘤基因信息,通过监测患者的CTC类型与数量可了解其肿瘤病灶动态变化情况,并且有助于评估治疗效果,辅助开展个体性治疗方案。同时,临床检测CTC具有良好的简便性,并且能够持续进行动态检测,从而实时给予反馈辅助医师及时给予治疗策略改变,更有助于提升临床治疗效果,延长患者生存时间。既往研究发现,将CTC用于肺癌患者治疗评估中效果理想,有助于评估患者预后并指导临床治疗,但不同的研究采用不同的方法界定CTC,且样本量偏少。本次研究本院主要对NSCLC患者治疗中循环肿瘤细胞动态变化做了记录分析,同时探讨了CTC同无进展生存期(progression-free survival,PFS)、客观缓解率(objective response rate,ORR)、总生存期(overall survival,OS)的关系,具体报道如下。, 百拇医药(黄韵坚 徐海鹏 黄诚)
