Adherence to follow-up in women with cervical intraepithelial neoplasia grade 1

ObjectivesAdherence to follow-up is crucial for cervical intraepithelial neoplasia grade 1 (CIN1) because these women have a chance of progression to high-grade premalignant cervical lesions and cervical cancer. This study aimed to evaluate the rate of adherence to follow-up in women who were initially diagnosed with CIN 1 over a period of 24 months and to evaluate the regression and progression rate of CIN 1.Material and methodsOf 1050 women who visited a colposcopy clinic from October 2013 through March 2017, 138 with histologically proven as CIN 1 were recruited. Adherence to follow-up, the regression and progression rate of CIN 1 were retrospectively assessed.ResultsOf the 138 women, 86 (62.3%) followed regularly until the study endpoint at 24 months. During the study period, 10 women received ablative treatment. The regression rate in women who had surveillance with cervical cytology was 69.7%, persistent disease of 18.4%, and progression to CIN 2–3 of 11.8%. In contrast, 80% of women who received ablative treatment had regression, 20% of them had persistent disease but none had progression.ConclusionsNearly 40% of women with CIN 1 were lost to follow-up at 24 months. Adherence to the follow-up should be emphasized to all women. Intensive interventions to improve adherence and clinical outcome might be an option, particularly among women with poor compliance.

Smoking cessation counseling in women with genital intraepithelial neoplasia

Objective

Cigarette smoking is a risk factor for cervical, vaginal, vulvar, and anal dysplasia. We will study the prevalence of cigarette smoking in patients with genital dysplasia and effect of counseling on smoking cessation.

Methods

All patients with genital dysplasia were screened for smoking history. One clinician provided smoking cessation counseling using the US Department of Health 5 A's technique: ask patients about their smoking status, advise smokers to quit, assess their readiness to quit, assist with their smoking cessation effort, and arrange for follow-up visits. Patients were informed on how smoking may cause worsening of genital dysplasia and increased risk of progression to cancer. Each patient received 2 counseling sessions, but no pharmacological or psychological interventions. Smoking cessation was evaluated by patient self-report via phone or during clinic visits.

Results

From January 2007 to December 2010, 344 patients were referred to our gynecologic oncology clinic for evaluation of genital dysplasia. Patients who were smokers (n = 125, 36%) were counseled to cease smoking in 2 counseling sessions, with 100% compliance for attendance. At study analysis (July 2011), 83 patients still smoke and 40 patients quit smoking (smoking cessation rate of 32%). Caucasian patients (P = .0013) and patients with vulvar dyplasia (P = .411) seemed to smoke more than other races and patients with cervical/vaginal dysplasia respectively.

Conclusion

Smoking cessation counseling for the genital dysplasia patients who smoked was associated with smoking cessation in 32% of the patients.     

宫颈上皮内瘤样病变Ⅲ级治疗与预后分析

目的探讨宫颈上皮内瘤样病变Ⅲ级(CINⅢ)的治疗方法。方法对1972年至1998年在我院治疗的宫颈原位癌48例和宫颈重度不典型增生28例进行回顾性分析。结果原位癌患者中,行次广泛全子宫切除术的29例和全子宫切除术的11例,术后均无复发;6例行宫颈锥形切除术,1例术后14年再次发生原位癌;重度不典型增生的患者,行子宫切除术和锥切术患者均无复发。结论宫颈CINⅢ发病年龄出现年轻化趋势,全子宫切除术与次广泛全子宫切除术预后相近,全子宫切除术可作为原位癌患者的首选治疗方法;单纯宫颈锥切术有术后复发可能,术后应严密随访;重度不典型增生可行宫颈锥切术或LEEP手术,术后应定期随诊。     

Apoptosis-related proteins and cervical intraepithelial neoplasia in human immunodeficiency virus-seropositive women

OBJECTIVE: To evaluate the expression of bcl-2, p-53, Ki-67, and apoptosis as evidenced by nuclear DNA fragmentation in cervical biopsies obtained from human immunodeficiency virus (HIV)-seropositive and HIV-seronegative women with a history of intravenous drug abuse. METHODS: We investigated 109 consecutive cervical biopsies (73 from HIV seropositive and 36 from HIV seronegative patients), including 86 cervical intraepithelial neoplasia (CIN) lesions and 23 normal cervical epithelium. The markers of apoptosis and proliferation were detected using immunostaining methods on paraffin sections. The associations between HIV status and the intensities of immunostaining were tested by univariate and multivariable methods. RESULTS: The severity of CIN correlated directly with the intensities of p-53 (Spearman Rho = 0.19; P = 0.05) and Ki-67 immunostaining (Spearman Rho = 0.46, P < 0.001) and with apoptosis and Bcl-2 expression (chi-square for trend = 10.6 and 3.91 , P < 0.001 and P = 0.048, respectively).After adjustment, by logistic regression analysis, for the potential confounding effect of severity of CIN and Human Papillomavirus (HPV) infection, apoptosis was five times more common in cervical biopsies of HIV seropositive compared to HIV seronegative patients (27 out of 73 as compared to 4 out of 36, adjusted Odds Ratio = 5.0; 95% confidence intervals = 1.56-16.33, P = 0.007). The adjusted odds ratio of increasing p53 immunodetection was significantly higher in biopsies obtained from HIV-seropositive patients compared to HIV seronegative controls (OR = 8.7; 95% confidence intervals = 2.97-25.3, P < 0.0001). CONCLUSION: Markers of apoptosis such as nuclear DNA fragmentation and p-53 immunoreactivity are more intensely expressed in cervical biopsies of normal and dysplastic epithelium of HIV-seropositive compared to HIV-seronegative women.     

Pregnancy outcome in patients treated with cervical conization for cervical intraepithelial neoplasia

Objective

To examine the causal contribution of conization to premature delivery.

Methods

This was a retrospective, case-control, multicenter study of women who underwent conization in 5 hospitals in the Basque Country (Spain) from 1998 to 2007. Three study groups were established: group A, post-conization infant deliveries; control group B, pre-conization infant deliveries; and control group C, infant deliveries without conization.

Results

Comparing group A with group C, there was a higher rate of preterm delivery before 35 weeks (5.3% versus 1.6%), a lower mean birth weight (3156.2 g versus 3328.5 g), and a greater prevalence of infants under 2500 g (10.6% versus 3.7%). There were no significant differences between group A and group B: preterm delivery before 35 weeks (5.3% versus 4.8%), mean birth weight (3156.2 g versus 3119.4 g), and prevalence of infants under 2500 g (10.6% versus 10.6%).

Conclusion

Pregnancy in women post-conization was associated with a risk of preterm delivery. However, there were no significant differences between women who underwent conization before and those who underwent conization after delivery. Cervical conization does not necessarily increase the risk of preterm delivery in subsequent pregnancy. Conization should be considered an indicator of such risk because it is associated with pregnancy complications arising from socio-epidemiologic factors present in women requiring conization that are also present in women who have premature delivery.     

Factors associated with positive margins in patients with cervical intraepithelial neoplasia grade 3 and postconization management

Objective

To evaluate the risk factors for positive margins in cervical intraepithelial neoplasia (CIN) grade 3 and the outcomes of postconization management.

Methods

A retrospective review of the records of 1113 women who underwent conization for CIN 3 between 2000 and 2008.

Results

Positive margins occurred in the following: 104 (10.7%) women with severe dysplasia versus 37 (26.2%) with carcinoma in situ; 32 (4.8%) treated with cold knife conization versus 109 (24.1%) treated with the loop electrosurgical excision procedure (LEEP); and 124 (11.6%) premenopausal versus 17 (35.4%) postmenopausal women. None of the women with severe dysplasia had invasive disease in the repeat excision specimen, whereas 3 (8.6%) women with carcinoma in situ had residual microinvasive carcinoma.

Conclusion

LEEP, carcinoma in situ, menopausal status, and larger area of lesion are risk factors for positive margins. For women with CIN 3 and positive margins, follow-up at an interval of 6 months or repeat excision are treatment options. However, when repeat excision is technically impossible, whether simple hysterectomy or radical surgery is a rational treatment option requires further investigation.

宫颈冷刀锥切治疗宫颈上皮内瘤样病变Ⅲ级的评价

目的 探讨阴道镜下多点活检与宫颈冷刀锥切对于宫颈上皮内瘤样病变Ⅲ级（CINⅢ）病理诊断的符合情况。方法 1995—2005年间对北京大学人民医院92例阴道镜下多点活检病理诊断为CINⅢ的患者进行宫颈冷刀锥切治疗，比较阴道镜下多点活检与宫颈冷刀锥切的病理结果之间的差异。结果 92例中有52例多点活检与冷刀锥切的病理结果一致，符合率为56．5％，40例多点活检与冷刀锥切的结果不同，其中11例多点活检诊断为CINⅡ／Ⅲ，而冷刀锥切诊断为微小浸润癌。结论 宫颈锥切是宫颈上皮内瘤样病变的一种重要诊断与治疗方法。阴道镜下多点活检病理提示宫颈上皮内瘤样病变Ⅲ级并伴随腺体受累可能是存在宫颈浸润癌的一个高危因素。人乳头瘤病毒（HPV）感染与宫颈病变有关，但未发现HPV高危型检测数值高低与患者病理级别之间的联系。     

子宫颈锥切术在子宫颈上皮内瘤变诊断和治疗中的价值

目的 明确宫颈锥切术能否被阴道镜下多点活组织检查（活检）代替以及探讨宫颈锥切术在宫颈上皮内瘤变（CIN）诊断与治疗中的价值。方法 回顾性分析近5年来,因宫颈病变同时行宫颈细胞学检查、阴道镜下多点活检和宫颈锥切术的患者54例,采用自身对照法,对比研究宫颈锥切术和阴道镜下多点活检的病理检查结果。结果 宫颈锥切术与阴道镜下多点活检的病理检查结果完全符合者22例（40.7%),不符合者32例（59.3%)。在因除外浸润癌而行宫颈锥切术的31例中,与阴道镜下多点活检的病理检查结果一致者仅13例（41.9%)。宫颈锥切术后,因发现早期浸润部,行广泛子宫切除术者2例（3.7%);因CINⅢ级（CINⅢ）或微小逮润癌行全子宫切除术者13例（24.1%)。39例（73.2%)患者宫颈锥切术后密切随诊,保留了生育功能,在平均为18.3个月的随诊期内,无一例出现宫颈细胞学检查异常,其中3例妊娠并已分娩,宫颈锥切术主要的并发症是术后出血。结论 宫颈锥切术在CIN治疗中具有举足轻重的重要价值。它不能被阴道镜下多点活检所取代,对于患者CINⅢ又要保留生育功能的年轻患者,宫颈锥切术是较为适当的治疗方法。     

Asymptomatic vasculitis of the uterine cervix in presence of cervical intraepithelial neoplasia grade III

Case report A 34-year-old woman was diagnosed to have a high-grade cervical intraepithelial neoplasia and was treated by large loop excision of the transformation zone. Histology of the excised cone confirmed the diagnosis but also showed evidence of vasculitis of medium-sized vessels of the cervix. The woman was referred to a physician to rule out underlying systemic disease. Extensive laboratory and clinical screening was negative.Discussion The clinical significance and management of asymptomatic isolated vasculitis of the uterine cervix are discussed.     

Risk factors for human papillomavirus persistence among women undergoing cold-knife conization for treatment of high-grade cervical intraepithelial neoplasia

Objective

To investigate the risk factors potentially associated with high-risk human papillomavirus (HPV) persistence in women undergoing cold-knife conization (CKC) for treatment of high-grade cervical intraepithelial neoplasia (CIN).

Methods

Medical records of women who underwent CKC for treatment of CIN 2/3 between 2007 and 2012 at a tertiary hospital in Ankara, Turkey, were retrospectively analyzed. Cases involving persistent HPV infection after 1 year of follow-up were identified. Using univariate and multivariate analyses, the impact of various factors such as patient age, menopausal status, parity, high-risk HPV type, excised cone dimensions (width, height, and depth), and surgical margin status on high-risk HPV persistence was assessed.

Results

A total of 292 women underwent CKC for treatment of CIN 2/3 within the study period. After women with a subsequent diagnosis of cervical cancer, subsequent total hysterectomy, and inadequate follow-up data were eliminated, 113 women were eligible for final analysis. High-risk HPV persistence was detected in 24 (21.2%) women, and multivariate analysis revealed that patient age and cone depth were significant independent predictors (P < 0.05).

Conclusion

High-risk HPV persistence may be encountered after CKC procedures. It is important to evaluate persistent HPV infections after treatment because affected women are at increased risk for disease persistence, recurrence, and progression.     

Digital camera assessment for detection of cervical intraepithelial neoplasia in rural El Salvador.

OBJECTIVE: To explore the feasibility of digital photography for primary cervical cancer screening in a low-resource setting in El Salvador. METHODS: Three independent examiners performed Pap test, visual inspection, digital camera assessment and colposcopy on each subject. RESULTS: Lesions were detected in 99 of 504 patients (20%) by visual inspection, 72/504 (14%) by DART and 90/504 (18%) by colposcopic impression. Seven of 504 patients (1.3%) had CIN on histology. Pap detected 2 of 7 subjects (29% sensitivity) (C.I. 4%, 56%), visual inspection detected 5 of 7 (71% sensitivity, C.I. 34%, 95%), digital assessment detected 6 of 7 (86% sensitivity C. I. 45%, 99%), and colposcopic impression detected 5 of 7 (71% sensitivity, C.I. 34%, 95%). CONCLUSION: This small pilot trial demonstrates the potential value and feasibility of performing digital camera assessment of the reproductive tract on women in a developing country setting.
