Abstract:
瞄准:为了在食道的有鳞的房间癌(ESCC ) 检验人的乳头状瘤病毒(HPV ) 的存在,从哥伦比亚和智利收集的标本分别地在大陆的北、南部的结束定位了。方法:我们分别地从哥伦比亚和智利检验了 47 和 26 个修理福尔马林、嵌入石蜡的 ESCC 标本。HPV 为 PCR 用 GP5+/GP6+ 教材对被检测,并且由南部的污点分析证实了。定序 L1 区域碎片的分析被用来识别 HPV 遗传型。另外,所有标本染色的 P16 (INK4A ) 蛋白质免疫被进行。结果:HPV 在 21 个 ESCC 标本(29%) 被检测。定序 L1 区域碎片的分析在 6 个哥伦比亚的盒子(13%) 中并且在 5 个智利人盒子(19%) 中识别了 HPV-16 染色体。HPV-18 在哥伦比亚然而并非在任何智利人盒子中在 10 种情况(21%) 中被检测。自从智利人 ESCC ,盒子有 HPV-16 的更高的流行(没有统计意义),但是 HPV-18 的显著地更低的流行比在哥伦比亚的情况中( P = 0.011 )尽管二个国家有类似的 ESCC 发生率,HPV相关的 ESCC 的频率不能被影响 ESCC 的发生的风险因素强烈影响。HPV-16 染色体经常是更多在 p16 检测了积极的癌,尽管差别不是统计上重要的。HPV-18 察觉率没与 p16 表示显示出任何协会。区分得好的肿瘤趋于有 HPV-16 或 HPV-18,但是协会不是统计上重要的。除 HPV-16 以外的 HPV 遗传型或 18 没在任何一个土地被检测。结论:HPV-16 和 HPV-18 遗传型能在从二个南方美国人国家收集的 ESCC 标本被发现。在在 ESCC 的 HPV-16 存在和 p16 表示之间的关系上的进一步的研究将帮助在 ESCC 位于 HPV 的存在下面的机制的理解。Keywords:

AIM:To investigate the relation of human papillomavirus (HPV) and esophageal squamous cell carcinoma (ESCC) in Iranian patients as compared to normal controls. METHODS:Using MY09/MY11 consensus primers, we compared the prevalence of a HPV L1 gene in tumor tissues from 38 ESCC cases and biopsied tissues from 38 endoscopically normal Iranian individuals.We also compared the presence of HPV16 and HPV18 in the same samples using type-specific E6/E7 primers.RESULTS: Fourteen (36.8%) of the 38 ESCC samples but only 5 (13.2%) of the 38 control samples were positive for the HPV L1 gene (P = 0.02).Five (13.2%) of the ESCC samples but none of the control samples were positive for the HPV16 E6/E7 gene (P = 0.05).Three (7.9%) of the ESCC samples and 5 (13.2%) of the control samples were positive for the HPV18 E6/E7 gene (P = 0.71). CONCLUSION:Our data are consistent with HPV DNA studies conducted in other high-risk areas for ESCC.HPV should be considered as a potential factor contributing to the high incidence of ESCC in Iran and other high-incidence areas of the world.

本邦におけるHPV関連中咽頭癌の発生率やタイピング,臨床上の特徴などを明らかにするため,多施設による前向き研究を行った。2009年5月から症例の登録が開始され,倫理委員会の承認が得られた21の施設によって,中咽頭癌148例,コントロールの正常口蓋扁桃53例が登録された。PCRによるHPV検出は,中咽頭癌症例では76例(51.4%)に認められ,タイピングの結果はHPV16が69例(90.8%),HPV18:2例(2.6%),HPV58:2例(2.6%),その他HPV31,HPV35,HPV56が各1例(1.3%)であった。HPV陽性中咽頭癌は側壁に多く発生し,非喫煙者,非飲酒者に多い傾向が認められた。正常口蓋扁桃ではHPVの感染は認められなかった。ハイブリッドキャプチャー2法を用いたブラッシングによるHPVの検出はPCRと比較すると,感度90.7%,特異度97.1%であった。

HPV infection is known to cause cervical cancer. This study aimed to identify the variant of HPV genotypes of cervical precancerous lesions from low grade squamous intraepithelial lesion (LSIL) and high grade squamous intraepithelial lesion (HSIL). This was an explorative study using formalin fix paraffin embedded (FFPE) from cervical precancerous lesions at Dr. Soetomo Hospital, Surabaya. DNA was extracted from FFPE and hybridized for HPV genotyping using Ampliquality HPV Type Express kit (AB ANALITICA) by reverse line blot techniques. The results showed that there were variants of HPV genotype in LSIL. The variants were HPV16 (8/15), HPV18 (3/15), HPV52 (1/15), HPV6+31 (1/15), HPV6+18 (1/15), and HPV72+68 (1/15), and in HSIL which were HPV16 (4/10), HPV18 (2/10), HPV59 (1/10), HPV6+45 (1/10), HPV61+26 (1/10), and HPV16+31 (1/10). The characteristics of infection in LSIL were single infection of high-risk (hr) HPV and multiple infection of low-risk (lr)+hr HPV, and in HSIL were single infection of HPVhr, multiple infection of HPVhr+hr and HPVlr+hr. In conclusion, HPV prevalence in cervical precancerous lesions is single infection by HPV16 (48%), HPV18 (20%), HPV52 (4%), HPV59 (4%), and multiple infection by HPV6+31, HPV6+18, HPV6+45, HPV16+31, HPV61+26, HPV72+68 is 4%.

症例は,70歳,女性.1990年2月ごろよりの下血を主訴に同年5月15日当科初診す.肛門指診にて肛門縁より約3cm,6時方向に硬い腫瘤を触知し,注腸X線検査,大腸内視鏡検査にて2型の肛門管癌と診断,手術を施行したところ,病理検査所見はsquamous cell carcinoma pm n2(+)ly2 v0であった.また新鮮摘出標本の分子生物学的検査所見としてHPV-DNAアッセイ(HPV 6, 11, 16, 18, 31, 33, 35)が陽性であった.近年,HPV感染と悪性病変との関係が示唆され,なかでも肛門管癌とHPV感染の関係は,肛門管癌において肛門性交の既往のある男性同性愛者がhigh risk groupであると報告されて以来,とくに欧米において注目きれ,両者の関係を研究していくことが肛門管の発癌機構解明,ひいては発癌防止のためにも必要と考えられる.今回われわれは,文献検索上未だ本邦にて報告のないHPV感染を伴った肛門管癌の1例を経験したので報告する.

This study was undertaken to investigate the distribution of human papillomavirus (HPV) subtypes and cervical lesions in Busan.Furthermore, the cytological and histological findings of cervical lesions were compared to determine the usefulness of the currently released vaccines.HPV subtypes of 2,130 patients who visited Haeundae Paik Hospital between January 2013 and March 2016 were analyzed by the HPV 9G DNA chip.Liquid-based cytological examination was performed, and subtypes were classified according to the 2001 guidelines of The Bethesda System.Biopsy or hysterectomy specimens were subjected to hematoxylin and eosin staining for histological examinations.Of the total 2,130 cases, 1,254 (58.9%) were positive for HPV, and 876 (41.1%) were negative.Of these, 152 (7.1%), 97 (4.6%) and 80 (3.8%) were identified as HPV 16, 68 and 56, respectively.Of the 329 cases encompassing the above three HPV subtypes, histopathological analysis diagnosed 155 (47.1%) cases with CIN2 or higher grade.Notably, the occurrences of HPV subtypes 16, 68, 56, 58 and 51 were most frequently diagnosed in Busan.Further analysis revealed that administration of Gardasil Ⓡ 9, the currently available vaccine in the market, exerts no protection against subtypes 68, 59 and 51.This study aims to provide an important reference for future HPV vaccination programs in Busan.

中咽頭扁平上皮癌53例を対象にHPV感染と治療成績との関連について検討を行った。53例中14例(26%)がHPV陽性であったが,扁桃原発例に限れば19例中11例(58%)が陽性であった。HPV陽性14例中12例(86%)がHPV16陽性で,HPV18およびHPV58陽性が各1例みられた。疾患特異的5年生存率はHPV陽性例の方が陰性例に比べ有意に高い結果となった。放射線化学療法施行症例においてもHPV陽性例の方が陰性例に比べ有意に疾患特異的5年生存率は高い結果となり,HPV陽性例では11例全例局所は制御されたが,陰性例では22例中9(41%)が局所再発した。以上の結果から,中咽頭癌症例の治療成績の向上のためにはHPV感染の有無による層別化が必要であり,HPV陰性例では局所の制御が課題であると考えられた。

Background and Objective: Human papillomavirus (HPV) is one of the possible etiologic factors in development of esophageal squamous cell carcinoma (ESCC). In this study we aimed to study the role of HPV in ESCC. Patients and Methods: In this study, 140 cases of ESCC were analyzed for the HPV DNA by polymerase chain reaction (PCR) using GP5+/GP6+ primers for L1 open reading frame (ORF) to amplify a 150-bp segment of HPV L1 ORF. This region was subsequently sequenced to identify the type of HPV. Results: A total of 140 patients enrolled in our study. In this respect, 50.7% of them were females and 49.3% were males, aged between 20 and 81 years old. In addition, 33 tumor specimens (23.6%) and 12 (8.6%) non-involved tumor margins were HPV positive. In HPV positive tumor cases, 36% were also positive in tumor margins. The HPV positive cases were 21.7% males and 25.3% females. There was no correlation between the presence and types of HPV with patients’ sex and age. The frequency of HPV subtypes in tumoral regions were as follow: HPV-16: 60.6%, HPV-18: 30.3%, HPV-33: 6.1%, and HPV-31: 3 %. We found only HPV-16 in tumor margins. Conclusion: Our results support a causal association between HPV infection and ESCC which is consistent with HPV studies conducted in other high-risk areas.

人的乳头状瘤病毒(HPV ) 是包括感染皮肤、有粘液的有鳞的 epithelia 的一组小 DNA 病毒的最普通的性传播疾病之一。液体祷告 microarray 技术(LBMA ) 被用来评估 24 HPV 遗传型在证实了诺思中国的肥沃、不肥沃的男性以便有男不孕的精液参数和关系上的 HPV 感染的效果能被讨论。1138 个题目的一个总数在这研究被招募;142 是 HPV 积极的(12.48 %;) 。在 523 证实的肥沃的男性之中,仅仅 35 是 HPV 积极的(6.70 %;) ,并且他们中的二个有多重感染。在 615 不肥沃的男性之中, 107 是 HPV 积极的(17.4 %;) ,并且他们中的 29 个有多重感染。不肥沃的男性让相对高的 HPV 感染与证实的肥沃的男性相比评价。精子进步活动性(PR ) 和正常形态学率显著地在 HPV 积极的题目被减少。HPV-45, HPV-52, HPV-18, HPV-59 和 HPV-16 感染更经常在不肥沃的男性。因此, HPV 感染是仔细与将减少的男不孕有关精子 PR 和形态学。HPV-45, HPV-52, HPV-18, HPV-59 和 HPV-16 感染似乎是主要风险因素。
