OBJECTIVETo detect and type human papilloma virus (HPV) in the warts of oral mucosa from HIV-positive patients, and better understand the biological characters of these oral warts.

METHODSPolymerase chain reaction (PCR) was used to detect and type HPV infection by consensus HPV primers Gp5+/Gp6+ and specific HPV primers (HPV6/11, 16, 18, 31, 33) in 34 cases of oral mucosa warts from HIV-positive patients.

RESULTSThe HPV infection rate was 88.2% by consensus HPV primers Gp5+/Gp6+; the HPV infection rate of HPV6/11, 16, 18, 31 was respectively 47.06%, 11.67%; 2.94%, and 5.88% by specific HPV primers.

CONCLUSIONMost lesions of oral warts from HIV-positive patients are associated with the infection of HPV. The low risk HPV6/11 infection is more common than the high risk HPV16, 18, 31.

OBJECTIVETo analyze the relationship between the prognosis of patients with oropharyngeal squamous cell carcinoma (OSCC) and human papillomavirus (HPV) infection in OSCC.

METHODSSixty-six patients with oropharyngeal carcinoma who met the enrollment criteria during the period from January 1999 to December 2009 were retrospectively reviewed. The presence or absence of HPV oncogenic types in OSCC specimen was determined by multiplex polymerase chain reaction (PCR). Overall survival (OS) and disease specific survival (DSS) for HPV-positive and HPV-negative patients were estimated by Kaplan-Meier analysis. Cox regression model was used for multivariate analysis.

RESULTSHPV-DNA was detected in 11(16.7%) of all specimens. Among them, 7 were positive for HPV-16, 1 for HPV-16/11, 1 for HPV-35, 1 for HPV-58/52, and 1 for HPV-33/52/54. With the follow-up of 3-78 months (a median of 24.5 months), patients with HPV-positive tumors had significantly better overall survival (χ2=5.792, P=0.016) and disease specific survival (χ2=4.721, P=0.030), the 3-year OS and DSS were 90.0% vs 52.4% and 90.0% vs 56.4%, respectively. Multivariate analysis by Cox regression model showed that HPV infection and nodal status were both independent prognostic factors for patients with OSCC (P<0.05).

CONCLUSIONSPatients with HPV-positive OSCC have significantly better prognosis than patients with HPV-negative tumors. HPV infection is an independent prognostic factor.

OBJECTIVEDiscussion of the relationship between cervical cytology and high-risk HPV test and lesions in the cervical tissue.

METHODThe 254 infertile patients were graded into 4 groups based on the results of cervical cytology and high-risk HPV test. The patients in group A were the cervical cytology -positive and HPV-positive. The cervical cytology -positive and HPV-negative patients were in group B. The cervical cytology -negative and HPV-positive patients were in group C and cervical cytology -negative and HPV-negative in group D. Retrospective analysis was used in the relationship between the results and lesions in the cervical tissue.

RESULTSThe incidence of CIN II and higher grade than CIN II was significant higher in group A than in group B (P < 0.01). The incidence of CIN I was no difference among A, B and C group (P > 0.05). The sensitivity was 100.0% and the specificity was 46.74% when cervical cytology was used to test the CIN II grade. But the sensitivity changed to 97.22% and the specificity 87.16% when both of the cervical cytology and HPV test were used.

CONCLUSIONThe cervical cytology is the first choice in cervical examination. And the accuracy will significant higher when the HPV test is used simultaneously.

OBJECTIVETo detect the high-risk human papillomavirus (HPV) infectious condition in women with abnormal cytology and evaluate its values in the screening of high grade squamous intraepithelial lesion.

METHODSWe used hybrid capture 2 (hc2) method to examine 949 patients with abnormal cervical cytology results [ > or =atypical squamous cells of undetermined significance (ASC-US) according to the 2001 The Bethesda System diagnosis criteria]. All subjects also received colposcopy for tissue studies.

RESULTSAmong 949 patients with abnormal cytology, the diagnoses of atypical squamous cells (ASC), low grade squamous intraepithelial lesion (LSIL), and high grade squamous intraepithelial lesion (HSIL) were made in 432, 310, and 207 patients, respectively. The high-risk HPV positive rate in ASC, LSIL, and HSIL were 40.3%, 44.8%, and 89.4%, respectively. The numbers of patients with pathologically confirmed results of negative intraepithelial lesion or malignancy (NILM), cervical intraepithelial neoplasia 1, 2, 3 (CIN 1, 2, 3), and squamous cell carcinoma (SCC) were 335, 388, 118, 101, and 7, and the high-risk HPV positive rate was 17.3%, 66.2%, 92.4%, 97.0%, and 100%, respectively. Among patients with atypical squamous cells of undetermined significance (ASC-US), rate of HSIL in high-risk HPV positive group and negative group were 10.2% and 0.8%, respectively (P < 0.01). In screening HSIL, the sensitivities of cytology [ > or = ASC cannot exclude HSIL (ASC-H)] and cytology ( > or = ASC-H) plus high-risk HPV testing were 0.925 and 0.991, and the specificities were 0.510 and 0.748, respectively (P < 0.01). Sensitivitives of cytology ( > or = LSIL) and cytology (> or = LSIL) plus high risk HPV in detecting HSIL were 0.898 and 0.982, respectively, while the specificitives were 0. 567 and 0.779, respectively (P < 0.01).

CONCLUSIONSThe positive rate of high-risk HPV increases with the gravity of cervical lesions. In patients with abnormal cervical cytology, high-risk HPV testing can improve the sensitivity and specificity in the screening of HSIL.

BACKGROUND: We evaluated the performance of various commercial assays for the molecular detection of human papillomavirus (HPV); the recently developed AdvanSure HPV Screening real-time PCR assay (AdvanSure PCR) and the Abbott RealTime High Risk HPV PCR assay (Abbott PCR) were compared with the Hybrid Capture 2 HPV DNA Test (HC2). METHODS: All 3 tests were performed on 177 samples, and any sample that showed a discrepancy in any of the 3 tests was genotyped using INNO-LiPA HPV genotyping and/or sequencing. On the basis of these results, we obtained a consensus HPV result, and the performance of each test was evaluated. We also evaluated high-risk HPV 16/18 detection by using the 2 real-time PCR assays. RESULTS: Among the 177 samples, 65 were negative and 75 were positive in all 3 assays; however, the results of the 3 assays with 37 samples were discrepant. Compared with the consensus HPV result, the sensitivities and specificities of HC2, AdvanSure PCR, and Abbott PCR were 97.6%, 91.7%, and 86.9% and 83.9%, 98.8%, and 100.0%, respectively. For HPV type 16/18 detection, the concordance rate between the AdvanSure PCR and Abbott PCR assays was 98.3%; however, 3 samples were discrepant (positive in AdvanSure PCR and negative in Abbott PCR) and were confirmed as HPV type 16 by INNO-LiPA genotyping and/or sequencing. CONCLUSIONS: For HPV detection, the AdvanSure HPV Screening real-time PCR assay and the Abbott PCR assay are less sensitive but more specific than the HC2 assay, but can simultaneously differentiate type 16/18 HPV from other types.

OBJECTIVETo study the relationship between thinprep cytologic test and the types of human papilloma virus (HPV) infection in cervical precancerous lesion screening.

METHODSTo perform high-risk HPV types test in 1375 samples. Choose 256 positive samples to take thinprep cytologic test (TCT) and directed biopsies under colposcopy. Adopting two-channels real time PCR to genotype and quantify eight high risk HPV DNA (high risk types: HPV 16, 18, 45, 31; intermediate risk types: HPV 33, 52, 58, 67).

RESULTSThere are 256 positive samples in High risk HPV DNA test (18.62%). WNL rate for TCT is 16.41% (42/256), ASCUS and above rate for TCT is 83.59% (214/256). There is no statistically significant difference in the viral loads of HPV infection rate between the TCT negative patients and positive patients (P > 0.5). Positive correspondence rate for TCT and biopsy are 92.86% (39/42), 81.36% (48/59), 85.19% (23/27) and 9/10.

CONCLUSIONHigh-risk HPV types checking combined with TCT and biopsy can raise positive rate significantly. It should be used as a reliable method for early diagnosis in cervical cancer and CIN screening.

Human papillomavirus (HPV) infection is an essential cause of cervical cancer. HPV testing therefore may maximize the clinical benefits of cervical screening and abnormal cervical cytology management. A negative HPV test in combination with a normal Pap test result in women age 30 years or older allows the safe extension of the cervical screening interval to 3 years. However, because HPV infection is common in young women and is usually transient, HPV testing is not recommended as part of primary cervical screening for women younger than 30 years. HPV testing is recommended for women of any age as a triage test with atypical squamous cells of undetermined significance (ASC-US) results and as an option for follow-up of women with HPV-positive ASC-US, atypical squamous cells "cannot rule out high-grade", low-grade squamous intraepithelial lesions, or atypical granular cells not found to have CIN 2/3. HPV testing is also recommended as an alternative to colposcopy and/or cytology for follow-up of treated cases. Proper use of HPV testing improves the management of women with cytologic abnormalities.

OBJECTIVETo detect the human papillomavirus (HPV) infectious condition in women with abnormal cytology and evaluate its values in the screening of high grade cervical intraepithelial lesion.

METHOD101 patients who underwent thinprep cell test(TCT) with abnormal cervical cytology were selected to undergo HPV test, all subjects also received tissue biopsy at the same time.

RESULTS(1) Among the 101 patients,the incidence rates of high risk HPV infection of those with ASCUS, LSIL, HSIL and squamous cell carcinoma were 84.2%, 88.6%, 100.0% and 2/2 respectively. (2) Among the patients with abnormal cytology,the number of patients with pathologically confirmed results of CIN I and CIN II or worse were 20 and 81, the incidence rates of high risk HPV infection of those with CIN I and CIN II or worse were 60.0% and 97.5% respectively. (3) In the ASCUS group, the incidence rates of CIN II or worse with high risk HPV infection were 87.5% and the incidence rates of CIN II or worse without high risk HPV infection were 16.7%. (4) The prevalence of high risk HPV types from highest to lowest order were follow: HPV16 (39.6%), 58 (17.8%), 52 (16.8%), 18 (9.9%), 33 (9.9%).

CONCLUSIONSThe infection rate of high risk HPV was positively correlated with the levels of cervical lesions. HPV test is a good triage approach for the patients with ASCUS. HPV16, 58, 52, 18, 33 are the most common in the patients of cervical lesions.

OBJECTIVETo investigate the significance of human papillomavirus test in triage of patients with atypical squamous cell of undetermined significance (ASCUS) diagnosed by cervical cytology.

METHODSHuman papillomavirus test,colposcope and cervical biopsy were performed in 184 patients with a referral diagnosis of ASCUS by cervical cytology.

RESULTSConfirmed by pathological diagnosis of cervical biopsy, 112 cases were chronic inflammation (60.87%), 33 CIN I (17.93%), 17 CIN II (9.24%), 8 CIN III (4.35%), 4 cervical squamous carcinoma (2.17%) and 10 condyloma (5.43%). Of the 184 women with cytological ASCUS, 124 (67.39%) cases were positive in high-risk HPV test among which 66 cases were histologically confirmed as chronic inflammation (53.23%), 22 as CIN I (17.74%), 16 as CIN II (12.90%), 8 as CIN III (6.45%), 4 as cervical squamous carcinoma (3.23%) and 8 as condyloma (6.45%). The positive rate of HPV in groups of ASCUS were higher than those with negative HPV (P < 0.003).

CONCLUSIONWomen with ASCUS should be tested for HPV. Cervical biopsy under colposcopy is recommended for women with HR-HPV infection.
