| 1 | Incidence of human papilloma virus in esophageal squamous cell carcinoma in patients from the Lublin region显示文摘AIM:To assess the prevalence of human papilloma virus(HPV) in esophageal squamous cell carcinoma(ESCC) in the south-eastern region of Poland.METHODS:The study population consisted of 56 ESCC patients and 35 controls.The controls were patients referred to our department due to other nonesophageal and non-oncological disorders with no gross or microscopic esophageal pathology as confirmed by endoscopy and histopathology.In the ESCC patients,samples were taken from normal mucosa(56 mucosa samples) and from the tumor(56 tumor samples).Tissue samples from the controls were taken from normal mucosa of the middle esophagus(35 control samples).Quantitative determination of DNA was carried out using a spectrophotometric method.Genomic DNA was isolated using the QIAamp DNA Midi Kit.HPV infection was identified following PCR amplification of the HPV gene sequence,using primers MY09 and MY11 complementary to the genome sequence of at least 33 types of HPV.The sequencing results were computationally analyzed using the basic local alignment search tool database.RESULTS:In tumor samples,HPV DNA was identified in 28 of 56 patients(50%).High risk HPV phenotypes(16 or/and 18) were found in 5 of 56 patients(8.9%),low risk in 19 of 56 patients(33.9%) and other types of HPV(37,81,97,CP6108) in 4 of 56 patients(7.1%).In mucosa samples,HPV DNA was isolated in 21 of 56 patients(37.5%).High risk HPV DNA was confirmed in 3 of 56 patients(5.3%),low risk HPV DNA in 12 of 56 patients(21.4%),and other types of HPV in 6 of 56 patients(10.7%).In control samples,HPV DNA was identified in 4 of 35 patients(11.4%) with no high risk HPV.The occurrence of HPV in ESCC patients was significantly higher than in the controls [28 of 56(50%) vs 4 of 35(11.4%),P < 0.001].In esophageal cancer patients,both in tumor and mucosa samples,the predominant HPV phenotypes were low risk HPV,isolated 4 times more frequently than high risk phenotypes [19 of 56(33.9%) vs 5 of 56(8.9%),P < 0.001].A higher prevalence of HPV was identified in female patients(71.4% vs 46.9%).Accordingly,the high risk phenotypes were isolated more frequently in female patients and this difference reached statistical significance [3 of 7(42.9%) vs 2 of 49(4.1%),P < 0.05].Of the pathological characteristics,only an infiltrative pattern of macroscopic tumor type significantly correlated with the presence of HPV DNA in ESCC samples [20 of 27(74.1%) vs 8 of 29(27.6%) for ulcerative or protruding macroscopic type,P < 0.05].The occurrence of total HPV DNA and both HPV high or low risk phenotypes did not significantly differ with regard to particular grades of cellular differentiation,phases in depth of tumor infiltration,grades of nodal involvement and stages of tumor progression.CONCLUSION:Low risk HPV phenotypes could be one of the co-activators or/and co-carcinogens in complex,progressive,multifactorial and multistep esophageal carcinogenesis. | Andrzej Dabrowski Wojciech Kwasniewski Tomasz Skoczylas Wiesawa Bednarek Dorota Kuzma Anna Gozdzicka-Józefiak | 2012 | World Journal of Gastroenterology2012，18，40： | 55 |
| 2 | DF方案联合放疗治疗晚期食管癌的临床研究显示文摘目的:探讨放疗配合DF方案化疗能否提高治疗食管癌的疗效。方法:将76例食管癌患者随机分两组,每组38例。A组为单纯放疗组,B组为放疗化疗结合组。放疗均采用直线加速器高能X线常规照射,5次/周,2GY/次,DT60~70GY。B组患者在放疗先行1周期化疗,放疗结束1周再按计划每21天行1周期化疗,共给4周期。结果:1、2、3年生存率,A组分别为15例(39.5%)、10例(26.3%)、4例(10.5%);B组分别为22例(57.9%)、16例(42.1%)、11例(28.9%),B组1、2、3年生存率高于单放组(P<0.05),且无严重不良反应发生。结论:放疗配合DF方案化疗治疗食管癌的疗效优于单纯放疗。 | 吴立新 黄玉霞 赵伟 | 2010 | 吉林医学2010，31，36： | 5 |
| 3 | 通用引物巢式PCR法对哈萨克族食管鳞癌HPV感染的检测显示文摘目的:应用通用引物巢式PCR技术检测新疆哈萨克族食管鳞癌人乳头瘤病毒(HPV)的感染率,并探讨HPV与新疆哈萨克族食管鳞癌的关系.方法:提取新疆哈萨克族食管鳞癌及正常食管组织的DNA,应用通用引物HPV MY09/11及HPV G5+/6+进行巢式PCR,检测新疆哈萨克族食管鳞癌中HPV的感染率.结果:巢式PCR法扩增后检测到食管鳞癌中HPV感染率为66.67%,正常对照组为12.12%,两者差异有统计学意义(P<0.05).结论:本实验结果表明HPV可能是新疆哈萨克族食管癌发生的一个重要病因学因素,结合通用引物巢式PCR法可以更加方便可靠的检测HPV-DNA. | 陈卫刚 杨春梅 徐丽红 张宁 刘晓燕 马云贵 霍小玲 韩玉胜 田德安 郑勇 | 2012 | 世界华人消化杂志2012，20，12： | 4 |
| 4 | Relationships of early esophageal cancer with human papillomavirus and alcohol metabolism显示文摘BACKGROUND It is well known that an alcohol consumption habit together with inactive heterozygous aldehyde dehydrogenase-2(ALDH2)is an important risk factor for the development of esophageal squamous cell carcinoma(ESCC).It remains controversial whether human papillomavirus(HPV)infection contributes to the occurrence/development of ESCC.There has been no study in which the relationship between ESCC and HPV in addition to alcohol dehydrogenase-1B(ADH1B)and ALDH2 genotypes was evaluated.AIM To evaluate relationships between HPV infection and development of esophageal cancer,particularly early esophageal cancer,based on ADH1B/ALDH2 polymorphisms.METHODS We conducted an exploratory retrospective study using new specimens,and we enrolled 145 patients who underwent endoscopic resection for superficial ESCC and had been observed for more than two years by both physical examination and endoscopic examination in Hokkaido University Hospital.Saliva was collected to analyze genetic polymorphisms of ADH1B/ALDH2.We performed in situ hybridization for resected specimens to detect HPV by using an HPV type 16/18 probe.RESULTS HPV was detected in 15(10.3%)of the 145 patients with ESCC.HPV-positive rates in inactive ALDH2*1/*2 and ALDH2*1/*1+*2/*2 were 10.8%and 9.8%,respectively(P=1.00).HPV-positive rates in slow-metabolizing ADH1B*1/*1 and ADH1B*1/*2+*2/*2 were 12.0%and 10.0%,respectively(P=0.72).HPV-positive rates in the heavy or moderate alcohol consumption group and the light or rare consumption group were 11.1%and 8.7%,respectively(P=0.68).HPV-positive rates in the heavy smoking group and the light or no smoking group were 11.8%and 8.3%,respectively(P=0.59).The 3-year incidence rates of secondary ESCC or head and neck cancer after initial treatment in the HPV-positive and HPVnegative groups were 14.4%and 21.4%(P=0.22),respectively.CONCLUSION In the present situation,HPV status is considered to be less important than other risk factors,such as alcohol consumption,smoking habit,ADH1B/ALDH2 polymorphisms,and HPV status would therefore have no effect on ESCC risk management. | Masaki Inoue Yuichi Shimizu Marin Ishikawa Satoshi Abiko Yoshihiko Shimoda Ikko Tanaka Sayoko Kinowaki Masayoshi Ono Keiko Yamamoto Shoko Ono Naoya Sakamoto | 2020 | World Journal of Gastroenterology2020，26，39： | 2 |
