| 1 | Comparison of the eighth version of the American Joint Committee on Cancer manual to the seventh version for colorectal cancer: A retrospective review of our data显示文摘AIM To analyze the survival trends in colorectal cancer(CRC) based on the different classifications recommended by the seventh and eighth editions of the American Joint Committee on Cancer staging system(AJCC-7^(th) and AJCC-8^(th)).METHODS The database from our institution was queried to identify patients with pathologically confirmed stage 0-Ⅳ CRC diagnosed between 2006 and 2012. Data from 2080 cases were collected and 1090 cases were evaluated through standardized inclusion and exclusion criteria. CRC was staged by AJCC-7^(th) and then restaged by AJCC-8^(th). Five-year disease-free survival(DFS) and overall survival(OS) were compared. SPSS 21.0 software was used for all data. DFS and OS were compared and analyzed by Kaplan-Meier and Log-rank test.RESULTS Linear regression and automatic linear regression showed lymph node positive functional equations by tumornode-metastasis staging from AJCC-7^(th) and tumornode-metastasis staging from AJCC-8^(th). Neurological invasion, venous infiltration, lymphatic infiltration, and tumor deposition put forward stricter requirements for pathological examination in AJCC-8^(th) compared to AJCC-7^(th). After re-analyzing our cohort with AJCC-8^(th),the percentage of stage ⅣB cases decreased from 2.8% to 0.8%. As a result 2% of the cases were classified under the new ⅣC staging. DFS and OS was significantly shorter(P = 0.012) in stage ⅣC patients compared to stage ⅣB patients.CONCLUSION The addition of stage ⅣC in AJCC-8^(th) has shown that peritoneal metastasis has a worse prognosis than distant organ metastasis in our institution's CRC cohort. Additional datasets should be analyzed to confirm these findings. | Guo-Jun Tong Gui-Yang Zhang Jian Liu Zhao-Zheng Zheng Yan Chen Ping-Ping Niu Xu-Ting Xu | 2018 | World Journal of Clinical Oncology2018，9，7： | 11 |
| 2 | Lack of CD44 variant 6 expression in rectal cancer invasive front associates with early recurrence显示文摘AIM: To investigate the prognostic value of CD44 variant 6 (CD44v6), a membranous adhesion molecule, in rectal cancer. METHODS: Altogether, 210 rectal cancer samples from 214 patients treated with short-course radiotherapy (RT, n = 90), long-course (chemo) RT (n = 53) or surgery alone (n = 71) were studied with immunohistochemistry for CD44v6. The extent and intensity of membranous and cytoplasmic CD44v6 staining, and the intratumoral membranous staining pattern, were analyzed.RESULTS: Membranous CD44v6 expression was seen in 84% and cytoplasmic expression in 81% of the cases. In 59% of the tumors with membranous CD44v6 expression, the staining pattern in the invasive front was determined as 'front-positive' and in 41% as 'front-negative'. The latter pattern was associated with narrower circumferential margin (P = 0.01), infiltrative growth pattern (P < 0.001), and shorter disease-free survival in univariate survival analysis (P = 0.022) when compared to the 'front-positive' tumors. CONCLUSION: The lack of membranous CD44v6 in the rectal cancer invasive front could be used as a method to identify patients at increased risk for recurrent disease. | Suvi Tuulia Avoranta Eija Annika Korkeila Kari Juhani Syrjnen Seppo Olavi Pyrhnen Jari Toivo Tapio Sundstrm | 2012 | World Journal of Gastroenterology2012，18，33： | 9 |
| 3 | Tumor budding as a potential histopathological biomarker in colorectal cancer:Hype or hope?显示文摘Colorectal cancer(CRC),the third most commonly diagnosed type of cancer in men and women worldwide is recognized as a complex multi-pathway disease,an observation sustained by the fact that histologically identical tumors may have different outcome,including various response to therapy.Therefore,particularly in early and intermediate stage(stages Ⅱ and Ⅲ,respectively) CRC,there is a compelling need for biomarkers helpful of selecting patients with aggressive disease that might benefit from adjuvant and targeted therapy.Histopathological examination shows that likely other solid tumors the development and progression of human CRC is not only determined by genetically abnormal cells,but also by intricate interactions between malignant cells and the surrounding microenvironment.This has led to reconsider the features of tumor microenvironment as potential predictive and prognostic biomarkers.Among the histopathological biomarkers,tumor budding(i.e.,the presence of individual cells and small clusters of tumor cells at the tumor invasive front) has received much recent attention,particularly in the setting of CRC.Although its acceptance as a reportable factor has been held back by a lack of uniformity with respect to qualitative and quantitative aspects,tumor budding is now considered as an independent adverse prognostic factor in CRC that may allow for stratification of patients into risk categories more meaningful than those defined by tumor-node-metastasis staging alone,and also potentially guide treatment decisions,especially in T2-T3 N0(stage Ⅱ) CRCs. | Fabio Grizzi Giuseppe Celesti Gianluca Basso Luigi Laghi | 2012 | World Journal of Gastroenterology2012，18，45： | 8 |
| 4 | CD133阳性/阴性肺癌细胞的分选、鉴定及差异基因的筛选显示文摘背景与目的研究表明多种实体肿瘤中存在肿瘤干细胞(cancer stem cells,CSCs),肿瘤干细胞与非肿瘤干细胞的生物学特性存在已有的明显差异,而CD133被认为是肿瘤干细胞的标记物,因此CD133阳性细胞与CD133阴性细胞可能存在明显差异。本研究通过分选人肺腺癌A549细胞中的CD133阳性及CD133阴性细胞,鉴定两组细胞的生物学特性并在人组织标本进行验证,利用基因芯片筛选转移相关差异基因。方法采用磁式分选(magnetic activated cell sorting,MACS)的方法对人肺腺癌A549中CD133阳性细胞、CD133阴性细胞进行分选,通过无血清条件培养、平板克隆、血清诱导分化及基因芯片等实验,比较两组细胞'sphere'形成、细胞增殖、细胞分化以及差异基因,并在人组织标本进行CD133表达与临床特性的验证分析。结果 CD133阳性细胞能在无血清培养基中悬浮生长并形成'sphere';其平均克隆形成率(57.1%)明显高于CD133阴性细胞(3.3%);CD133阳性细胞能被血清诱导分化、表达腺癌标志物CK7;两组细胞中的19个转移基因表达水平相差两倍或以上,差异最高达12倍;肺癌组织中CD133阳性细胞主要分布于癌巢周边,数量稀少,其表达与肿瘤组织学分型、分级及临床分期无关。结论 CD133阳性肺腺癌A549细胞具有CSCs特性;两组细胞在转移相关基因的表达存在明显差异,其中CD82可能在CD133阳性细胞的转移机制中起重要作用。 | 郑少秋 李书华 王红艳 谢晓斌 张雅洁 | 2015 | 中国肺癌杂志2015，18，3： | 6 |
| 5 | Twist在结直肠癌中的表达及在上皮间质转化中的作用显示文摘目的观察结直肠癌中Twist基因的表达以及与结直肠癌恶性生物学行为的相关性。方法采用免疫组化S-P法及逆转录-聚合酶链反应检测10例正常结直肠粘膜、25例结直肠癌癌灶中心及癌灶边缘组织、9例淋巴结转移灶中Twist、E-cadherin、Vimentin、N-cadherin表达水平。结果 Twist的表达与结直肠癌患者的性别、年龄、肿瘤原发部位、分化程度无统计学差异(P>0.05),与有无淋巴结转移、Dukes分期、TNM分期有统计学差异(P<0.05)。4种蛋白在以上4种组织中的表达差异有统计学意义(P<0.05)。Twist、Vimentin、N-cadherin在结直肠癌灶边缘组织和淋巴结转移灶中的表达高于正常结直肠粘膜和癌灶中心中的表达(P<0.05)。E-cadherin在正常结直肠粘膜和癌灶中心中的表达显著高于结直肠癌灶边缘组织和淋巴结转移灶中的表达(P<0.05)。Twist、E-cadherin、Vimentin、N-cadherin在4种组织中阳性表达率与其相应mRNA的表达水平呈显著正相关(P<0.05)。在结直肠癌及淋巴结转移灶中,E-cadherin表达水平与Twist呈负相关(r=-0.263,P<0.05;r=-0.605,P<0.05),Vimentin的表达水平与Twist呈正相关(r=0.214,P<0.05;r=0.470,P<0.05),N-cadherin的表达水平与Twist呈正相关(r=0.381,P<0.05;r=0.581,P<0.05),而E-cadherin表达水平与Vimentin呈负相关(r=-0.562,P<0.05;r=-0.591,P<0.01),E-cadherin表达水平与N-cadherin呈负相关(r=-0.267,P<0.05;r=-0.617,P<0.01)。结论 Twist可能通过调控上皮间质转化(epithelial-mesenchymail transition,EMT)从而参与了结直肠癌的浸润、转移等过程,所以结直肠癌中Twist的表达及EMT发生可能成为独立于TNM分期以外判断结直肠肿瘤预后及浸润转移的生物学指标。 | 任林飞 程勇 贾健锋 徐维 | 2011 | 第三军医大学学报2011，33，22： | 3 |

| 7 | Novel biomarkers for patient stratification in colorectal cancer:A review of definitions,emerging concepts,and data显示文摘Colorectal cancer(CRC) treatment has become more personalised,incorporating a combination of the individual patient risk assessment,gene testing,and chemotherapy with surgery for optimal care.The improvement of staging with high-resolution imaging has allowed more selective treatments,optimising survival outcomes.The next step is to identify biomarkers that can inform clinicians of expected prognosis and offer the most beneficial treatment,while reducing unnecessary morbidity for the patient.The search for biomarkers in CRC has been of significant interest,with questions remaining on their impact and applicability.The study of biomarkers can be broadly divided into metabolic,molecular,micro RNA,epithelial-to-mesenchymal-transition(EMT),and imaging classes.Although numerous molecules have claimed to impact prognosis and treatment,their clinical application has been limited.Furthermore,routine testing of prognostic markers with no demonstrable influence on response to treatment is a questionable practice,as it increases cost and can adversely affect expectations of treatment.In this review we focus on recent developments and emerging biomarkers with potential utility for clinical translation in CRC.We examine and critically appraise novel imaging and molecular-based approaches; evaluate the promising array of micro RNAs,analyze metabolic profiles,and highlight key findings for biomarker potential in the EMT pathway. | Manish Chand Deborah S Keller Reza Mirnezami Marc Bullock Aneel Bhangu Brendan Moran Paris P Tekkis Gina Brown Alex Mirnezami Mariana Berho | 2018 | World Journal of Gastrointestinal Oncology2018，10，7： | 2 |
