目的 分析早期结直肠癌内镜下治疗前行窄带成像结合放大内镜 (ME-NBI)和超声内镜技术的评估价值。方法 采用回顾性分析方法,以2021年1月— 2023 年 12月中山市第五人民医院收治的102例早期结直肠癌患者为观察对象,所有患者均接受内镜下黏膜切除术(EMR)或内镜黏膜下剥离术(ESD)治疗,根据内镜下治疗前是否进行ME-NBI和超声内镜检查分为研究组与对照组各51例。比较两组年龄、性别、肿瘤大小、直乙结肠占比及组织病理特征;比较两组治疗时间、ESD治疗后非治愈性切除发生率、治愈性切除率、并发症发生情况及再次ESD或外科手术治疗率。结果 两组年龄、性别、肿瘤大小、直乙结肠占比及组织病理比较差异均无统计学意义(P>0.05)。研究组中37例行ESD治疗,治疗时间为(120.6±140.3)min,12例行EMR治疗,治疗时间为(11.6±9.3)min,有2例不符合内镜下治疗指征,转外科手术治疗。对照组有38例行ESD治疗,治疗时间为(128.8±144.5)min,13例行EMR治疗,治疗时间为(12.5±9.5)min,两者治疗时间比较差异均无统计学意义(P>0.05)。研究组非治愈性切除率为7.84,低于对照组27.45;治愈性切除率为88.24,高于对照组72.55;研究组ESD手术并发症为8.11%,低于对照组31.58;ESD或外科手术率为6.12,低于对照组25.49(P<0.05),结论 ME-NBI和超声内镜对早期结直肠癌患者行内镜下治疗指征评估更准确,可提高治愈性切除率。
Objective To study the application value of magnifying endoscopy combined with narrow band imaging (ME-NBI)and ultrasonic endoscopy system before endoscopic treatment in patients with early colorectal cancer.Methods A retrospective analysis was carried out on 102 patients with early-stage colorectal cancer who were admitted to Zhongshan Fifth People’s Hospital from January 2021 to December 2023.All patients were treated with endoscopic mucosal resection(EMR)or endoscopic submucosal dissection(ESO).The patients were divided into study group(51 cases)and control group(51 cases)according to whether ME-NBI and ultrasonic endoscopy was performed before endoscopic treatment or not.The patient age,sex,volume of tumor,location of tumor and pathological result of the tumor were compared between two groups.Time for treatment,curative resection rate,non-curative resection rate and the complication incidence of ESD,incidences of second ESD or surgery were compared between the two groups.Results There were no statistical differences in age,sex,volume of tumor,location of tumor and pathological result of the tumor(P>0.05).In the study group,37 patients received ESD treatment,operation time was(120.6±140.3)minutes,and 12 patients received EMR treatment,operation time was(11.6±9.3)minutes,two cases were transferred to surgery due to endoscopic ultrasonography combined with magnifying endoscopy showed that they did not meet the indications for ESD treatment.In the control group,38 patients received ESD treatment,operation time was(128.8±144.5)minutes,13 patients received EMR treatment,operation time was(12.5±9.5)minutes.There was no significant difference in treatment duration between the two groups.The non-curative resection rate of the study group was 7.84%,which was significantly lower than that in the control group(27.45%),and the curative resection rate(88.24%)was significantly higher than that in the control group(72.55%).The complications of ESD surgery in the study group were 8.11%,lower than 31.58% in the control group.The rate of second ESD or surgery was 6.12%,lower than 25.49% in the control group(P<0.05).Conclusions ME-NBI and endoscopic ultrasound are more accurate in the evaluation of endoscopic indications for early colorectal cancer patients,and can improve the curative resection rate.
目的 分析贝伐珠单抗与化疗对晚期结直肠癌患者4种错配修复蛋白(MSH2、MLHI、MSH6、PMS2)水平影响。方法 选择2022年1月—2024年1月江苏省宿迁市中医院肿瘤科102例晚期结直肠癌患者,按抽签法分成两组,即化疗组及联合组,各51例。化疗组应用FOLFOX(亚叶酸钙+奥沙利铂+氟尿嘧啶)方案进行化疗,联合组采取贝伐珠单抗联合FOLFOX方案治疗。对比其肿瘤控制效果、免疫功能及MSH2、MLHI、MSH6和PMS2水平变化,并对比组间不良反应发生率。结果 联合组客观缓解率、疾病控制率高于化疗组(P<0.05);治疗后联合组患者CD4+ 、CD3+ 、CD8+ 、和CD4+ /CD8+数值高于化疗组,且两组治疗后均低于治疗前(P<0.05);治疗后两组患者MSH2、MLHI、MSH6和PMS2缺失率对比无统计学意义(P>0.05),但其阳性、阴性表达情况对比差异有统计学意义,联合组MSH2、MLHI、MSH6和PMS2阳性率低于化疗组(P<0.05);两组不良反应发生率对比差异无统计学意义(P>0.05)。结论 对晚期结直肠癌在化疗基础上增加贝伐珠单抗抗肿瘤效果显著,改善其免疫功能,虽无法改善患者错配修复蛋白缺损,但可辅助降低其阳性率,且不影响安全性。
Objective To analyze the effects of bevacizumab and chemotherapy on the levels of four mismatch repair proteins(MSH2,MLHI,MSH6,PMS2)in patients with advanced colorectal cancer.Methods A total of 102 patients with advanced colorectal cancer from the Oncology Department of Suqian Traditional Chinese Medicine Hospital in Jiangsu Province from January 2022 to January 2024 were selected,and were divided into two groups according to the drawing method,namely the chemotherapy group and the combination group,with 51 patients in each group.The chemotherapy group received FOLFOX(calcium folinate+oxaliplatin+fluorouracil)regimen for chemotherapy,while the combination group received bevacizumab combined with FOLFOX regimen for treatment.Tumor control effect,immune function,and changes in MSH2,MLHI,MSH6,and PMS2 levels,and its incidence of adverse reactions were compared.Results The objective remission rate and disease control rate of the combined group were higher than those of the chemotherapy group(P<0.05).After treatment,the CD4+ ,CD3+ ,CD8+ and CD4+ /CD8+ values in the combination group were higher than those in the chemotherapy group,and those after treatment were lower than those before treatment in both groups(P<0.05).After treatment,there were no significant differences in the deletion rates of MSH2,MLHI,MSH6,and PMS2 between the two groups of patients(P>0.05),but there was a significant difference in their positive and negative expression.The positive rates of MSH2,MLHI,MSH6,and PMS2 in the combination group were lower than those in the chemotherapy group(P<0.05).There was no significant difference in the incidence of adverse reactions between the two groups(P>0.05).Conclusions Adding bevacizumab on the basis of chemotherapy has a significant anti-tumor effect on advanced colorectal cancer,improving its immune function.Although it cannot improve the mismatch repair protein defect in patients,it can assist in reducing its positivity rate and has high safety.
结直肠癌(CRC)是全球第三大最常见的癌症,也是癌症相关死亡的第二大常见原因。结直肠癌肝转移(CRLM)是导致CRC患者死亡的主要原因,根治性肝切除术是目前有望治愈CRLM的唯一途径,但大部分患者不能进行根治性肝切除术。通过早期发现并进行针对性干预,能够改善患者的治疗效果及预后。文章通过综述CRLM的发病机制、诊疗现状及最新纳米诊疗方法,为深入探索高效诊疗方法提供思路。
Colorectal cancer(CRC)is the third most common cancer and the second most common cause of cancer-related death worldwide.Colorectal cancer liver metastases(CRLM)are the leading cause of death in patients with CRC.Radical hepatectomy is the only way to cure CRLM so far,while most patients cannot undergo radical hepatectomy.CRLM treatment efficacy and prognosis can be improved by early diagnosis and specialized intervention.This paper reviews the pathogenesis,diagnosis,and treatment status of CRLM and the latest nano-diagnosis and treatment methods so as to provide ideas for in-depth exploration of efficient diagnosis and treatment methods.
