To determine the cytologic and histologic correlation of atypical glandular cells of undetermined significance (AGUS) in Papanicolaou smears, a cytology file from January 1998 to May 1999 was reviewed. Surgical pathology files were searched to determine which patients received subsequent biopsies. One hundred thirty-two patients with AGUS were identified. Corresponding biopsies were available for 82 of these cases. AGUS has been sub-classified into 3 subtypes: 1) AGUS, favor reactive; 2) AGUS, not otherwise specified; and 3) AGUS, favor neoplasia. The pathologic findings for the respective Papanicolaou smears with the diagnosis of each subtype of AGUS through the follow-up period were as follows: benign lesions in 56.1%, 0%, and 1.2%; squamous intraepithelial lesions 2.4%, 0%, and 1.2%; glandular intraepithelial lesions 0%, 0%, and 17.1%; endometrial simple hyperplasia 1.2%, 0%, and 0%; and carcinoma 0%, 9.8%, and 11%, respectively. In conclusion, AGUS, on cervical cytologic screening, was correlated with significant pathologic findings in 41.5% of the patients (37.8% with preinvasive or invasive glandular lesions and 9.6% with combined squamous intraepithelial lesions). It is thought that intensive follow-up studies, including colposcopy, cervical biopsy, and curettage, should be recommended for complete evaluation of AGUS.

OBJECTIVETo determine the association between viral load of high risk human papillomavirus (HR-HPV) and cervical intraepithelial neoplasia (CIN).
METHODSCervical exfoliated cells were collected from 18 186 women aged 17 -59 from six urban areas and eight rural areas when they were screened in the cross-sectional population-based studies from 1999 to 2008. HR-HPV was detected by the Hybrid Capture 2 (hc2) system, and viral load was measured by the ratio of relative light units to standard positive control (RLU/PC). RLU/PC was categorized for analysis into four groups: negative [0, 1.00), low viral load [1.0, 10.00), moderate viral load [10.00, 100.00), and high viral load > or = 100.00. Cervical lesions were diagnosed by biopsies as normal, CIN 1, CIN 2, CIN 3 and squamous cervical cancer (SCC). Association between HR-HPV viral load and CIN was evaluated by unconditional multinomial logistic regression.
RESULTSThe HR-HPV infection rate of the population was 14.51% (2515/17334). 100.00% (29/29) of SCC, 97.63% (206/211) of CIN 3, 93.43% (199/213) of CIN 2, 75.04% (421/561) of CIN 1 and 10.17% (1660/16320) of normal women were positive for HR-HPV DNA. The median RLUs for the HR-HPV positive women with SCC, CIN 3, CIN 2, CIN 1 and normal were 320.85, 158.05, 143.70, 125.34 and 9.64, respectively. There were significant differences among the distributions of viral loads in each lesion (chi2 = 6190.40, P < 0.01). The severity of CIN increased with the viral load (chi2 = 5493.35, P <0.01). Compared with the risks of CINs in HR-HPV negative population, the risks of CINs in low, moderate and high viral loads were increased gradually [OR(95% CI) : CIN 1 : 9.01(6.31 - 12.87), 24.96(18.23 - 34.17) and 68.42(51.40 - 91.08); CIN 2 : 26.44(12.07 - 57.95), 98.53(49.54 - 195.98) and 322.88(168.62 - 618.27); CIN 3+ : 72.89(24.02-221.18); 343.58(121.81-969.09) and >999.99(473.38 - >999.99)], and there were obvious dose-response relationships (chi2trend was 3115.05, 2413.95 and 3098.57, respectively. P< 0.01). In each age group of the HR-HPV positive population,the risks of CIN 2 + in the women with moderate or high viral load were higher than the one with low viral load [OR(95% CI): <35 : 4.71(1.23 - 18.09) and 15.06(4.40 - 51.49); 35 -: 4.01 (1.62 -9.90) and 14.09(6.15 -32.28); 40 - : 3.06(1.52 -6.16) and 7.78(4.05 -14.95); > or =45: 3.50(1.36 -9. 01) and 7.57(3.13 - 18. 30)], and there was a positive correlation between the risk of CIN 2+ and the viral load (chi2trend was 51.33, 66.28, 53.64 and 51.00, respectively. P <0.01). The risk of CIN 2 + was highest among the women aged 40 - with high viral load [OR (95% CI) : 2.02 (1.15 - 3.52)].
CONCLUSIONThere is strong correlation between the HR-HPV viral load and the severity of CIN, and so is the correlation between the HR-HPV viral load and the risk of CIN 2 +. A moderate to high viral load of HR-HPV should be the major risk factor for the cervical cancer and CIN 2 and CIN 3, and there is a higher risk in the women aged 35 or older than the younger ones. Considering both the age and viral load could help the doctors to manage the screening women more effectively.

OBJECTIVETo evaluate the etiological significance of human papillomavirus (HPV) in cervical cancer and the clinical utility of HPV detection in cervical cancer screening.
METHODSHybrid capture II test was used to detect 13 high-risk HPV genotypes from cervical scrapes of 2636 women. Cervical cytology was also evaluated in 454 of them by ThinPrep Pap smear.
RESULTSAmong 2636 women, 699 (26.5%) were found to be high-risk HPV positive. The highest infection rate (59.4%) was found in the age group of < or = 20 years and the lowest infection rate in the age group of 41 approximately 50 years (21.0%). Significant differences in HPV infection rate were found between different cities in Guangdong province, such as those between Xinhui and Guangzhou, Xinhui and Shenzhen, Xinhui and Dongguan (P < 0.01). Fifteen out of 16 women (93.8%) with cervical carcinoma were infected with high-risk HPV versus 24 out of 125 women (19.2%) attending routine cervical cancer screening (P < 0.001). The HPV infection rate was 30.8% (142 out of 461) in women with cervical erosion, which was significantly lower than that in patients with cervical carcinoma (P < 0.001). HPV DNA were detected in 100% (2/2) of squamous cell carcinoma (SCC), 100% (12/12) high grade squamous intraepithelial lesion (HSIL), 88.9% (16/18) of low grade squamous intraepithelial lesion (LSIL) and 37.8% (28/74) of atypical squamous cells (ASC).
CONCLUSIONHigh-risk HPV genotypes are the major causes of cervical cancers and HPV detection is a reliable adjuvant tool for cervical cancer screening.

4.Detection and typing of human papillomavirus DNA by PCR using consensus primers in various cervical lesions of Korean women.
Journal of Korean Medical Science 1999;14(6):593-599
The association between cervical cancers and human papillomavirus (HPV) is now well established. To estimate the extent of infection with common HPVs among Korean women, we have examined 224 cervical scrapes of various cervical lesions. Detection and typing of HPVs were done by polymerase chain reaction (PCR) using consensus primers followed by restriction enzyme digestion and PCR using type-specific primers. The prevalence of total HPV infection in patients with cervical intraepithelial neoplasia (CIN) and cervical cancer were significantly higher than those in healthy women and patients with atypical squamous cells of undetermined significance (ASCUS). HPV typing in 41 invasive carcinomas of the cervix revealed the prevalence of HPV 16 in 15 cases, followed by HPV 58, 18, 33, 31, 52 and 35. The distribution pattern of HPV types in CIN were not much different from carcinomas. HPV types except HPV 18 had a tendency to show higher prevalence in high-grade squamous intraepithelial lesion (HSIL) than low-grade squamous intraepithelial lesions (LSIL), however, HPV 18 was detected in LSIL but not in HSIL. HPV 18 tended to have the worse clinical stage, although it was not statistically significant. These findings suggest the importance of HPV typing other than HPV 16 and 18 and a different clinicopathologic significance of HPV 18.

OBJECTIVETo evaluate the value of high-risk HPV (hrHPV) detection by Hybrid Capture II (HC2) in screening cervical intraepithelial neoplasm (CIN).
METHODSTotally 723 patients who had received a dual screening with thinprep cytologic test (TCT) and HC2 in our department were analyzed retrospectively. Among them, 350 patients received a triple examination with TCT, HC2, and colposcopic biopsy.
RESULTSAmong the 723 patients, the incidences of hrHPV infection with atypical squamous cell (ASC), low squamous intraepithelial lesion, and high squamous intraepithelial lesion were 70.7% (94/133), 88.9% (249/280), and 90.9% (90/99), respectively, significantly higher than 55.5% (117/211), the incidence of hrHPV infection with normal cytological results (P = 0.005, P < 0.001, P < 0.001, respectively). Among 350 cases who were received triple examination, the incidence of hrHPV infection with cervical intraepithelial neoplasia (CIN) 1 and CIN 2 were 88.9% (72/81) and 96.3% (52/54), significantly higher than 77.7% (153/197), the incidence of hrHPV infection with normal pathological results (P = 0.03, P = 0.002); The incidence of hrHPV infection with CIN 3 and squamous cancer were 91.7% (11/12) and 100.0% (6/6), also higher than normal cases. Among these 350 cases, the incidence of hrHPV infection with ASC was 79.3% (69/87). The incidence of CIN 2-3 with ASC and hrHPV infection was 38.0%, significantly higher than the incidence of CIN 2-3 with ASC and without hrHPV infection (5.9%) (P = 0.04).
CONCLUSIONhrHPV infection has a close relation with CIN, and the incidence of hrHPV infection increases along with the severity of CIN.
