- W4362506545 abstract "Laryngeal squamous cell carcinoma (LSCC) is a common malignant tumor of head and neck. Screening of target genes for malignant tumor therapy is one of the focuses of cancer research, with proto-oncogene and tumor suppressor gene as the breakthrough. It has become an urgent need to find the target gene related to the treatment and prognosis of LSCC.This study aims to explore the role of Lin28B and C-myc in LSCC by detecting the expressions of these two proteins and analyze the correlation between the expression of Lin28B and C-myc and clinicopathological features and prognosis of LSCC.We detected the expression of Lin28B and C-myc proteins in 102 specimens of LSCC and 90 specimens of adjacent tissues by immunochemistry, and analyzed the correlation between Lin28B and C-myc protein expressions in LSCC as well as the correlation between the expressions of the two proteins and the clinicopathological features of LSCC. At the same time, the Kaplan-Meier method was used to analyze the relation between Lin28B and C-myc protein levels with the postoperative survival rate of LSCC patients.The protein levels of Lin28B and C-myc in the LSCC tissnes were significantly higher than those in the adjacent tissues (both P<0.05),and there was a positive correlation between the expression of Lin28B and C-myc in LSCC (r=0.476, P<0.05). The expression of Lin28B protein was closely related to age, lymph node metastasis, clinical stage, tumor size, and pathological differentiation of LSCC patients (all P<0.05). while the expression of C-myc protein was closely related to lymph node metastasis, clinical stage, tumor size, and pathological differentiation of LSCC patients (all P<0.05). A relevant survival analysis showed that in patients with higher level of Lin28B (P=0.001) or C-myc protein (P<0.001), the postoperative survival rate was relatively low.Lin28B and C-myc proteins are highly expressed in LSCC with a positive correlation. Furthermore, they are closely related to lymph node metastasis, clinical stage, tumor size, pathological differentiation and prognosis, suggesting that both Lin28B and C-myc might be involved in the occurrence and development of LSCC.目的: 喉鳞癌是头颈部常见恶性肿瘤。将原癌基因与抑癌基因作为研究的突破口从而筛选恶性肿瘤治疗的靶基因是如今肿瘤研究焦点之一。寻找喉鳞癌治疗及预后相关的靶基因分子至关重要。本研究旨在检测Lin28B和C-myc蛋白在喉鳞癌及其对应癌旁组织中的表达,初步探讨其与喉鳞癌临床病理特征及预后的关系。方法: 采用免疫组织化学法检测102例喉鳞癌患者的癌组织及其对应的90例癌旁组织中Lin28B与C-myc蛋白的表达情况,分析Lin28B与C-myc蛋白在喉鳞癌中表达的相关性及其表达水平与喉鳞癌临床病理特征之间的关系。采用Kaplan-Meier法分析喉鳞癌患者术后生存率与Lin28B和C-myc蛋白表达水平之间的关系。结果: 与癌旁组织相比,Lin28B、C-myc蛋白的表达水平在喉鳞癌组织中均显著升高(均P<0.05)。且二者在喉鳞癌中表达存在正相关关系(r=0.476,P<0.05)。Lin28B蛋白的表达与喉鳞癌患者年龄、淋巴结转移情况、临床分期、肿瘤大小和病理分化程度密切相关(均 P<0.05)。C-myc蛋白的表达与喉鳞癌患者淋巴结转移情况、临床分期、肿瘤大小和病理分化程度密切相关(均P<0.05)。生存分析显示高表达Lin28B(P=0.001)或C-myc蛋白(P<0.001)的患者术后生存率较低,差异有统计学意义。结论: Lin28B及C-myc蛋白在喉鳞癌组织中高表达且呈正相关,两者均与患者的淋巴结转移情况、临床分期、肿瘤大小、病理分化程度及预后相关,提示Lin28B和C-myc可能都参与喉鳞癌的发生、发展。." @default.
