目的探讨HPV在宫颈高级别病变中的感染率及感染型别。方法采用导流杂交法分别检测CINII～Ⅲ30例和宫颈癌患者160例HPV基因型别,比较HPV感染与宫颈病变的关系。结果CINⅡ～III和宫颈癌患者HPV感染率均为90％,且以单型别感染为主,分别为70．37％（19／27）、81．94％（118／144）;在CIN II～Ⅲ中HPV58型、52型感染居多,宫颈癌则以HPV16型、18型感染最常见;无论宫颈鳞癌还是宫颈腺癌,以HPV16型检出率最高。结论HPV16型、18型是宫颈癌的主要致病型,不同病理类型并无HPV型别上的差异;宫颈上皮高级别内瘤变则以HPV58型、52型感染为主;对HPV58型、52型感染者应重视随访。     

Treatment of the patients with abnormal cervical cytology: a "see-and-treat" versus three-step strategy

Objective

To examine the correlation between cervical cytology and final histological results in patients who have undergone loop electrosurgical excision procedure (LEEP) with or without colposcopy-directed biopsy.

Methods

A retrospective review was performed of 829 patients who underwent LEEP for abnormal cervical cytology at Gangnam Severance Hospital between January 2004 and December 2008. Patients were classified to three groups according to cervical cytology and also divided into two groups based on the treatment they received: see-and-treat group and the standard three-step group. Final histological results were compared for the each study group.

Results

There were no differences in the final histological results between see-and-treat and three-step group in patients with high-grade squamous intraepithelial lesions (HSIL) cytology (N=523) (p=0.71). However, in patients with low-grade squamous intraepithelial lesions (LSIL)/atypical squamous cells of undetermined significance (ASCUS) (N=257) or normal cytology (N=49), the final histological results were significantly different between see-and-treat and three-step group (p<0.001) and the rate of overtreatment was significantly higher in the see-and-treat group (p<0.001).

Conclusion

A see-and-treat protocol may be a viable alternative only in patients with HSIL cytology if colposcopic impression is suggestive of cervical intraepithelial neoplasia (CIN) 2 or 3 lesions.     

Prevalence of cervical human papilloma virus infection among married women in Vietnam, 2011

The burden of cervical cancer is increasing in Vietnam in the recent years, infection with high risk HPV being the cause. This study aimed to examine the prevalence of HPV and the distribution of HPV specific types among the general population in 5 big cities in Vietnam. Totals of 1500 women in round 1 and 3000 in round 2 were interviewed and underwent gynecological examination. HPV infection status, and HPV genotyping test were performed for all participants. Results indicated that the prevalence of HPV infection in 5 cities ranged from 6.1% to 10.2% with Can Tho having highest prevalence. The most common HPV types in all 5 cities were HPV 16, 18 and 58. Most of the positive cases were infected with high risk HPV, especially in Hanoi and Can Tho where more than 90% positive cases were high risk HPV. Furthermore, in Can Tho more than 60% of women were infected with multiple HPV types. The information from this study can be used to provide updated data for planning preventive activities for cervical cancer in the studied cities.     

宫颈细胞学诊断低度鳞状上皮内病变不除外高度鳞状上皮内病变的临床意义

目的:对宫颈细胞学诊断为低度鳞状上皮内病变不除外高度鳞状上皮内病变(low-grade squamous intraepithelial lesion,cannot exclude high-grade squamous intraepithelial lesion,LSIL-H)与TBS-2001系统中的LSIL、非典型鳞状细胞不除外高度病变(atypical squamous cells,cannot rule out a high grade lesion,ASC-H)和高度鳞状上皮内病变(high-grade squamous intraepithelial lesion,HSIL)的组织病理学结果进行比较,评估LSIL-H的临床风险。方法:对细胞学诊断异常标本即未明确意义的非典型鳞状上皮细胞(atypical squamous cells of undetermined significance,ASC-US)、LSIL、ASC-H和HSIL,采用盲法重新进行回顾性诊断,分级为ASC-US、LSIL、LSIL-H、ASC-H和HSIL。同时追踪组织病理学诊断结果,并分析高危型人乳头瘤病毒(highrisk-HPV)阳性率。结果:总共49000例被纳入分析。重新诊断后,LSIL-H有88例(88/49000,0.17%)。重新分级诊断前,LSIL-H在各异常分级中所占的比例分别为:ASC-US为19.32%(17/88)、LSIL为43.18%(38/88)、ASC-H为34.09%(30/88)、HSIL为3.41%(3/88)。LSIL-H罹患高度病变CIN2/3的概率要高于LSIL,两者相比差异有统计学意义(P<0.01),但均低于HSIL(P<0.01)。LSIL-H与ASC-H的CIN2/3患病率相当(分别为39.47%和38.46%),差异无统计学意义。结论:LSIL-H组织病理学结果证实,其与高度病变之间的关系与ASC-H相近,建议采用与ASC-H同样的方法对这类患者进行临床管理。     

Detection of human papilloma virus type 16 E6 mRNA in laryngeal squamous cell carcinoma by in situ hybridization

Objective  

Laryngeal squamous cell carcinoma (LSCC) is a common malignant tumor in Northeast China and is frequently associated with well-established risk factors like smoking and alcohol abuse. Human papilloma virus (HPV) is an epitheliotropic oncogenic virus that has been detected in a variety of head and neck tumors including LSCC. This retrospective study was to investigate the prevalence of HPV infection in patients with LSCC.     

Psychological effect of cervical cancer screening when changing primary screening method from cytology to high-risk human papilloma virus testing

From 2015, Norway has implemented high-risk human papilloma virus (hrHPV) testing in primary screening for cervical cancer. Women aged 34–69 years, living in four counties, have been pseudo-randomly assigned (1:1 randomization) to either hrHPV testing every 5 years (followed by cytology if hrHPV is positive), or cytology testing every 3 years (followed by hrHPV testing if low-grade cytology is detected). We compared anxiety and depression scores among participants by screening arm and results. In total, 1,008 women answered a structured questionnaire that included the validated Patient Health Questionnaire-4 (PHQ-4). The Relative Risk Ratio (RRR) of mild vs. normal anxiety and depression scores, and moderate/severe vs. normal anxiety and depression scores, were estimated by multinomial logistic regression with 95% confidence intervals (95% CIs). Compared to women who were screened with cytology, women randomized to hrHPV testing were not more likely to have mild anxiety and depression scores (RRR 0.96, CI 0.70–1.31) nor more likely to have moderate/severe anxiety and depression scores (RRR 1.14, CI 0.65–2.02). Women with five different combinations of abnormal screening test results were not more likely to have mild or moderate/severe vs. normal anxiety and depression scores than women with normal screening results. The likelihood of having abnormal long-term (4–24 months after the screening) anxiety or depression scores among women 34 years and older was not affected by screening method or screening results. The results of our study suggest that a change to hrHPV testing in primary screening would not increase psychological distress among participants.     

Human papilloma virus positive oropharyngeal squamous cell carcinoma: A growing epidemic

The incidence of oropharyngeal squamous cell carcinoma (OPSCC) is increasing despite a decrease in tobacco use. Almost 20–30% of patients with OPSCC do not have the traditional risk factors of smoking and alcohol use and in a vast majority of these patients, the human papilloma virus (HPV) appears to drive the malignant transformation. HPV induced malignant transformation is attributed to two viral oncogenes and their non-structural protein products (E6 and E7). These two proteins appear to affect carcinogenesis by their inhibitory effects on p53 and retinoblastoma proteins (Rb). Patients with HPV mediated OPSCC seem to have a better prognosis compared to their non-HPV counterparts. However, in the absence of strong evidence, standard of care at this time for OPSCC does not differ based on HPV status. Current research is focused on the role of de-escalation of treatment and elucidation of prognostic markers in this unique population. This review focuses on the pathogenesis of HPV mediated OPSCC and details the current evidence in the management of these patients.
