We as pathologists should know some basic information about HPV even though HPV testing might not be oerformed in your hospital, or the patients might not be able to pay for the test.
即使HPV检测在你们医院没有开展或病人没有经济能力支付这项检测。我们做为病理学医生应该知道一些关于HPV的基本知识。
USA FDA approved Roche HPV test can be used as the primary screening for the women 25 years and older. FDA approved it based on the clinial trial. But currently no clinical data demonstrate the safity of the approach.
In April 2014 US FDA approved cobas HPV test can be used as a primary screening test for women 25 and older.
Currently there are three optios for cervical cancer screening in the USA:
1. Pap test for women 21 or older, every three years
2. Cotesting (Pap+HPV) for women 30 and older, every five years
3. cobas HPV test for women 25 and older.

The U.S. Food and Drug Administration today approved the first FDA-approved HPV DNA test for women 25 and older that can be used alone to help a health care professional assess the need for a woman to undergo additional diagnostic testing for cervical cancer. The test also can provide information about the patient’s risk for developing cervical cancer in the future.
Using a sample of cervical cells, the cobas HPV Test detects DNA from 14 high-risk HPV types. The test specifically identifies HPV 16 and HPV 18, while concurrently detecting 12 other types of high-risk HPVs.
Based on results of the cobas HPV Test, women who test positive for HPV 16 or HPV 18 should have a colposcopy, an exam using a device that illuminates and magnifies the cervix so a physician can directly observe the cervical cells. Women testing positive for one or more of the 12 other high-risk HPV types should have a Pap test to determine the need for a colposcopy. Health care professionals should use the cobas HPV Test results together with other information, such as the patient screening history and risk factors, and current professional guidelines.
“Today’s approval offers women and physicians a new option for cervical cancer screening,” said Alberto Gutierrez, Ph.D., director of the Office of In Vitro Diagnostics and Radiological Health at the FDA’s Center for Devices and Radiological Health. “Roche Diagnostics conducted a well-designed study that provided the FDA with a reasonable assurance of the safety and effectiveness when used as a primary screening tool for cervical cancer.”
The FDA first approved the test, called the cobas HPV Test in 2011 for use in conjunction with or as a follow-up to a Pap test (cell cytology), which examines cervical cells for changes that might become cervical cancer.
Today’s approval expands the use of the test to include use as either a co-test or as a primary cervical cancer screening test, however; it does not change current medical practice guidelines for cervical cancer screening. These guidelines are developed, reviewed and modified by groups other than the FDA.
Genital HPVs are a group of more than 40 related viruses and, according to the Centers for Disease Control and Prevention (CDC), are the most common sexually transmitted infections. Approximately 14 “high-risk” HPV types are associated with cervical cancer.
In most cases, a high-risk HPV infection goes away on its own and does not cause any health problems. However, about 10 percent of women infected with high-risk HPV develop a persistent infection which may put them at risk of cancer. Virtually all cervical cancers are caused by HPV infections, with just two types, HPV 16 and HPV 18, responsible for approximately 70 percent of cervical cancers.
Data supporting the use of the cobas HPV Test as a primary screening test for cervical cancer included a study of more than 40,000 women 25 years and older undergoing routine cervical exams. Women who had a positive Pap test or whose cervical cells screened positive for HPV, as well as a subset of women whose Pap and HPV tests were both negative, underwent a colposcopy and cervical tissue biopsy. All biopsy results were compared to the Pap and cobas HPV Test results. Data from this study, which included three years of follow-up on women who went to colposcopy, showed that the cobas HPV Test is safe and effective for the new indication for use.
The cobas HPV Test is manufactured by Roche Molecular Systems, Incorporated, Pleasanton, Calif.
recently above short paper "commentary statment on HPV DNA test utilization" was published in several main pathology journals authourity guideline in the USA. I pasted the main points above for your reference. Basically the statement just repeat ed and highlighted the ASCCP guideline about HPV test. However they did not include some new study data. Many recent study results indicated that HPV DNA testing may be useful for women with ASC-H and AGC Pap. 以上是最近刊登在美国几家主要病理学杂志指导原则性的“关于HPV-DNA检测的应用的解释和说明”简报。我摘录主要内容供大家参考。基本上是基于ASCCP的指导原则上的重复声明。但是他们没有包括最新的研究数据。许多最新的研究是关于HPV-DNA检测在ASC-H和AGC的意义。

BACKGROUND: Primary cervical screening with both human papillomavirus (HPV) DNA testing and cytological examination of cervical cells with a Pap test (cytology) has been evaluated in randomized clinical trials. Because the vast majority of women with positive cytology are also HPV DNA positive, screening strategies that use HPV DNA testing as the primary screening test may be more effective. METHODS: We used the database from the intervention arm (n = 6,257 women) of a population-based randomized trial of double screening with cytology and HPV DNA testing to evaluate the efficacy of 11 possible cervical screening strategies that are based on HPV DNA testing alone, cytology alone, and HPV DNA testing combined with cytology among women aged 32-38 years. The main outcome measures were sensitivity for detection of cervical intraepithelial neoplasia grade 3 or worse (CIN3+) within 6 months of enrollment or at colposcopy for women with a persistent type-specific HPV infection and the number of screening tests and positive predictive value (PPV) for each screening strategy. All statistical tests were two-sided. RESULTS: Compared with screening by cytology alone, double testing with cytology and for type-specific HPV persistence resulted in a 35% (95% confidence interval [CI] = 15% to 60%) increase in sensitivity to detect CIN3+, without a statistically significant reduction in the PPV (relative PPV = 0.76, 95% CI = 0.52 to 1.10), but with more than twice as many screening tests needed. Several strategies that incorporated screening for high-risk HPV subtypes were explored, but they resulted in reduced PPV compared with cytology. Compared with cytology, primary screening with HPV DNA testing followed by cytological triage and repeat HPV DNA testing of HPV DNA-positive women with normal cytology increased the CIN3+ sensitivity by 30% (95% CI = 9% to 54%), maintained a high PPV (relative PPV = 0.87, 95% CI = 0.60 to 1.26), and resulted in a mere 12% increase in the number of screening tests (from 6,257 to 7,019 tests). CONCLUSIONS: Primary HPV DNA-based screening with cytology triage and repeat HPV DNA testing of cytology-negative women appears to be the most feasible cervical screening strategy.

HPV testing in combination with liquid-based cytology in primary cervical screening (ARTISTIC): a randomised controlled trial.
Conclusion: LBC combined with HPV testing resulted in a significantly lower detection rate of CIN3+ in the second round of screening compared with LBC screening alone, but the effect was small. Over the two screening rounds combined, co-testing did not detect a higher rate of CIN3+ or CIN2+ than LBC alone. Potential changes in screening methodology should be assessed over at least two screening rounds.
结论: 液基细胞学结合HPV检测同单用液基细胞检测比较应该在第二轮的筛查中大大降低CIN3+检出率,但是影响不大。在两轮筛查相结合,共同检测并没有发现率较高CIN3+或CIN2+比单独的液基细胞学。潜在的变化,在评估筛选方法至少应该进行两轮筛查。

BACKGROUND: A new test (careHPV; QIAGEN, Gaithersburg, MD, USA) has been developed to detect 14 high-risk types of carcinogenic human papillomavirus (HPV) in about 2.5 h, to screen women in developing regions for cervical intraepithelial neoplasia (CIN). We did a cross-sectional study to assess the clinical accuracy of careHPV as a rapid screening test in two county hospitals in rural China. METHODS: From May 10 to June 15, 2007, the careHPV test was done locally by use of self-obtained vaginal and provider-obtained cervical specimens from a screening population-based set of 2530 women aged 30 to 54 years in Shanxi province, China. All women were assessed by visual inspection with acetic acid (VIA), Digene High-Risk HPV HC2 DNA Test (HC2), liquid-based cytology, and colposcopy with directed biopsy and endocervical curettage as necessary. In 2388 women with complete data, 441 women with negative colposcopy, but unsatisfactory or abnormal cytology or who were positive on HC2 or the new careHPV test, were recalled for a second colposcopy, four-quadrant cervical biopsies, and endocervical curettage. An absence of independence between the tests was not adjusted for and the Bonferroni correction was used for multiple comparisons. FINDINGS: Complete data were available for 2388 (94.4%) women. 70 women had CIN2+ (moderate or severe CIN or cancer), of whom 23 had CIN3+. By use of CIN2+ as the reference standard and area-under-the-curve analysis with a two-sided alpha error level of 0.0083, the sensitivities and specificities of the careHPV test for a cut-off ratio cut-point of 0.5 relative light units, were 90.0% (95% CI 83.0-97.0) and 84.2% (82.7-85.7), respectively, on cervical specimens, and 81.4% (72.3-90.5) and 82.4% (80.8-83.9), respectively, on vaginal specimens (areas under the curve not significantly different, p=0.0596), compared with 41.4% (29.9-53.0) and 94.5% (93.6-95.4) for VIA (areas under the curve significantly different, p=0.0001 and p=0.0031, for cervical and vaginal-specimen comparisons for the careHPV test, respectively). The sensitivity and specificity of HC2 for cervical specimens were 97.1% (93.2-100) and 85.6% (84.2-87.1), respectively (areas under the curve not significantly different from the careHPV test on cervical specimens, p=0.0163). INTERPRETATION: The careHPV test is promising as a primary screening method for cervical-cancer prevention in low-resource regions.

BACKGROUND: In October 1999, we began to measure the effect of a single round of screening by testing for human papillomavirus (HPV), cytologic testing, or visual inspection of the cervix with acetic acid (VIA) on the incidence of cervical cancer and the associated rates of death in the Osmanabad district in India.
背景:1999年10月,在印度的Osmanabad区,我们开始衡量效果地进行单轮HPV筛查检测、细胞学检测、或直视下醋酸检查宫颈癌的发生率和与宫颈癌相关的死亡率。
METHODS: In this cluster-randomized trial, 52 clusters of villages, with a total of 131,746 healthy women between the ages of 30 and 59 years, were randomly assigned to four groups of 13 clusters each. The groups were randomly assigned to undergo screening by HPV testing (34,126 women), cytologic testing (32,058), or VIA (34,074) or to receive standard care (31,488, control group). Women who had positive results on screening underwent colposcopy and directed biopsies, and those with cervical precancerous lesions or cancer received appropriate treatment.
方法:本组随机分组实验,52个村庄进行分组,共有31746名年龄介于30到达9岁的健康女性,被随机分配到4个组,每组有13个村庄。分组随机指定接受HPV检测(34126名妇女)、细胞学检测(32058名妇女)、或直视下醋酸检查(VIA)(34074名妇女)或接受标准护理(31488名妇女,对照组)。对筛查结果为阳性进行阴道镜下活检。以及对那些有宫颈癌前病变和癌进行适当的治疗。
RESULTS: In the HPV-testing group, cervical cancer was diagnosed in 127 subjects (of whom 39 had stage II or higher), as compared with 118 subjects (of whom 82 had advanced disease) in the control group (hazard ratio for the detection of advanced cancer in the HPV-testing group, 0.47; 95% confidence interval [CI], 0.32 to 0.69). There were 34 deaths from cancer in the HPV-testing group, as compared with 64 in the control group (hazard ratio, 0.52; 95% CI, 0.33 to 0.83). No significant reductions in the numbers of advanced cancers or deaths were observed in the cytologic-testing group or in the VIA group, as compared with the control group. Mild adverse events were reported in 0.1% of screened women.
结果:在HPV检测组,被诊断为宫颈癌症127例(其中39例为STAGEII及以上);而相对于对照组[在HPV组检测晚期癌症的风险比:0.47;95%的可信区间(CI):0.32-0.69]为118例(其中82例有晚期的病变)。在HPV检测组中有34例死于癌症,而对照组有64例(风险比:0.52;95%的可信区间:0.38-0.83)。细胞学检测组或VIA组在晚期癌症或死亡病例的数据同对照组比较没有显著的减少。在筛查的妇女中被报道轻度不良反应为0.1%。
