To identify factors for predicting residual or recurrent cervical intraepithelial neoplasia (CIN) after cervical conization with negative margins. A total of 172 patients with histologically verified high‐grade squamous intraepithelial lesions who underwent conization with negative margins were recruited at the General Hospital of Tianjin Medical University from December 2006 to January 2016. Follow‐up comprised clinical examination, a liquid‐based cytology test, a human papillomavirus (HPV) DNA genotyping test, colposcopy assessment, and if indicated, colposcopy‐directed punch biopsy. The Kaplan‐Meier method was used to analyze the median recurrent time, whereas log‐rank tests and Cox regression models were used to determine the predictors of residual/recurrent CIN. Fourteen residual/recurrent cases (8.1%) were identified in 172 patients. In univariate analysis, cytologic abnormalities on follow‐up (P = .000), conization method (P = .017), HPV positivity at any visit (P = .000), persistent HPV infection postconization (P = .000), persistent infection with the same HPV genotype (P = .000), and HPV positivity at 18 months after conization (P = .000) were predictive factors of residual/recurrent CIN. The results of multivariate analysis further revealed that persistent HPV infection postconization (P = .035), HPV positivity at 18 months after conization (P = .017), and cytologic abnormalities on follow‐up (P = .000) had an increased risk of residual/recurrent CIN. During follow‐up, patients with persistent HPV infection or cytologic abnormalities were at high risk of residual/recurrent CIN and should be identified for close surveillance and monitoring. Meanwhile, patients with HPV who became negative within 18 months after treatment had a low risk of recurrence. 相似文献

To evaluate the prevalence of human papillomavirus (HPV) infection and its genotype among women with cervical lesions in Henan Province, central China. A total of 1317 cervical scrapes from patients with cervical intraepithelial neoplasia 1 (CIN1) (n = 91), CIN2/3 (n = 466), and cervical cancer (CC; n = 760) were collected from 2013 to 2018, and then tested for HPV genotypes using polymerase chain reaction followed by flow-through hybridization assay. The prevalence of HPV was 62.64% for patients with CIN1, 86.91% for patients with CIN2/3%, and 89.21% for patients with CC. In total, the HPV prevalence was 86.56%, and the most common HPV type was HPV16 (58.77%) followed by HPV58 (10.33%), 18 (7.67%), 52 (6.61%), and 33 (5.54%). In this study, the high-risk HPV cumulative attribution rate of nine-valent vaccine coverage was markedly higher than that of bivalent or quadrivalent vaccine coverage in each histopathological category or overall (P < .001). Single HPV infection was the main infection category in each histopathological diagnosis, and the total infection rate was 65.83% (867/1317; P < .001). The prevalence of HPV16 or single HPV infection increased with the severity of cervical lesions (P < .001). HPV16, 58, 18, 52, and 33 may be predominant high-risk factors for cervical lesions in Henan Province. The nine-valent prophylactic HPV vaccine is more effective than a bivalent or quadrivalent vaccine for protecting women from CC in the region. 相似文献

Infection with the human papillomavirus (HPV) is responsible for 99.7% of cervical cancers, the second most prevalent neoplasia in women worldwide and the fifth leading cause of death by cancer in this population. In Chile, the incidence rate is 14.4 cases per 100,000 women per year and it is considered a significant public health problem. The natural history of cervical cancer begins gradually from low-grade and high-grade squamous intraepithelial lesions to an invasive disease. In this study the frequency of HPV types was determined by HPV genotyping with reverse line blot hybridization in 200 cytobrushes of women with preneoplastic lesions in a high-risk population. HPV DNA was found in 89% of the lesions (83.3% of low-grade squamous intraepithelial lesions and 93.6% of high-grade squamous intraepithelial lesions). Multiple HPV infections were found in 14.4% and 15.5% of low- and high-grade lesions, respectively. HPV 16 was the most frequent genotype in single infections, followed by HPV 18. These results show that most of the preneoplastic lesions of the cervix (60%) were associated with HPV 16 and/or HPV 18, supporting the implementation of an HPV vaccination program in this high-risk population. 相似文献

In Iran, human papillomavirus (HPV) vaccination is not currently included in the national vaccination program and there are no comprehensive approaches to cervical screening program. Regional data on distribution of HPV types in women is important to predict the impact of current HPV vaccines. Although several studies on distribution of HPV types in cervical precancer and cancer have been conducted in Iran, in most of them HPV positive samples were subjected to specific‐primer genotyping (mainly 16 and 18), and leaving the other HPV genotypes almost undetermined. Therefore, the present study aimed to investigate the distribution of HPV types in cervical neoplasia from West and Northwest of Iran. A total of 112 women with atypia, cervical intraepithelial neoplasia, and invasive cervical cancer were included. A PCR assay was performed in all samples to detect the presence of the HPV genome using the GP5+/6+ L1 consensus primer set. All HPV positive samples were subjected for sequencing. In overall, HPV prevalence was 20% in atypica, 44.5% in cervical intraepithelial neoplasia I, 92.3% in cervical intraepithelial neoplasia II‐III, and 98.2% in invasive cervical cancer. The most frequent HPV type was HPV 16 (79.2%), which was followed by HPV types 18, 6, and 33 at the frequencies of 6.5%, 5.1%, and 2.7%, respectively. The least HPV types were found to be 31, 45, 53, 58, and 66. In conclusion, this study shows that the current HPV vaccines could have great impact to reduce the burden of cervical cancer in Iran. 相似文献

Macao is a densely populated city situated in East Asia where a relatively high prevalence of human papillomavirus (HPV) types 52 and 58 has been reported in women with invasive cervical cancer. To provide data for a population‐specific estimation on the impact of HPV vaccines, paraffin‐embedded tissues collected from women with invasive cervical cancer or cervical intrapeitheilal neoplasia grade 2 or 3 confirmed histologically were examined for HPV using the INNO‐LiPa kit. Of the 35 HPV‐positive patients with invasive cancer, one HPV type was detected in 68.6%, and 31.4% were co‐infected with more than one HPV type. Overall, HPV 16, HPV 18, HPV 52, and HPV 54 were the most common types found respectively in 57.1%, 17%, 11.4%, and 8.5% of patients with invasive cervical cancer. Among the 59 HPV‐positive patients with cervical intraepithelial neoplasia grade 2/3, 55.9% hardbored one HPV type, and 44.1% had co‐infections. The common HPV types found included HPV 16 (52.5%), HPV 52 (23.7%), HPV 58 (18.7%), and HPV 33 (17%). Although HPV 11 (a low‐risk type) was also found commonly in invasive cervical cancers (14.3%) and cervical intraepithelial neoplasia grade 2/3 (15.3%), the fact that they all existed as co‐infections with another high‐risk type suggested HPV 11 was not the cause of the lesion. The current vaccines targeting HPV 16/18 are expected to cover 62.9–74.3% of invasive cervical cancers and 32.2–55.9% of cervical intraepithelial neoplasia 2/3 in Macao. Widespread HPV vaccination is expected to reduce substantially the disease burden associated with cervical neoplasia in Macao. J. Med. Virol. 82:1600–1605, 2010. © 2010 Wiley‐Liss, Inc. 相似文献

A micronucleus is an additional small nucleus formed due to chromosomes or chromosomal fragments fail to be incorporated into the nucleus during cell division. In this study, we assessed the utility of micronucleus counting as a screening tool in cervical precancerous lesions in Thinprep cytological test smears under oil immersion. High risk HPV was also detected by hybrid capture-2 in Thinprep cytological test smears. Our results showed that micronucleus counting was significantly higher in high-grade squamous intraepithelial lesion (HSIL) and invasive carcinoma cases compared to low-grade squamous intraepithelial lesion (LSIL) and non-neoplastic cases. Receiver operating characteristic (ROC) curve analysis revealed that micronucleus counting possessed a high degree of sensitivity and specificity for identifying HSIL and invasive carcinoma. Cut-off of 7.5 for MN counting gave a sensitivity of 89.6% and a specificity of 66.7% (P = 0.024 and AUC = 0.892) for detecting HSIL and invasive carcinoma lesions. Multiple linear regression analysis showed that only HSIL and invasive cancer lesions not age, duration of marital life and number of pregnancy are significantly associated with MN counting. The positive rate of high risk HPV was distinctly higher in LSIL, HSIL and invasive cancer than that in non-neoplstic categories. In conclusions, MN evaluation may be viewed as an effective biomarker for cervical cancer screening. The combination of MN count with HPV DNA detection and TCT may serve as an effective means to screen precancerous cervical lesions in most developing nations. 相似文献
