阴道镜检查与宫颈电环锥切术在宫颈病变诊治中的应用

目的:探讨阴道镜检查与宫颈电环锥切术(LEEP)在宫颈鳞状上皮内病变(SIL)诊治中的应用价值。方法:回顾分析342例在我院经薄层液基细胞学技术(TCT)、高危型人乳头瘤病毒(HPV)检测和阴道镜检查综合初步诊断为宫颈SIL而行LEEP术患者的资料,采用自身对照法,以LEEP术组织病理学诊断为金标准,比较充分、不充分阴道镜检查组宫颈活检诊断宫颈病变与金标准诊断的符合率;比较充分阴道镜检查组镜下图像拟诊宫颈高级别鳞状上皮内病变(HSIL)、低级别鳞状上皮内病变(LSIL)与金标准诊断的符合率;并于术后定期随访,评价LEEP术诊治宫颈SIL的疗效。结果:充分阴道镜检查组宫颈活检诊断的宫颈病变与金标准诊断的符合率高于不充分阴道镜检查组活检诊断的符合率,差异有统计学意义(χ~2=87.27,P0.01);不充分阴道镜检查组宫颈活检诊断不足36例(50%),宫颈浸润癌漏诊4例(5.56%)。充分阴道镜检查组镜下图像拟诊HSIL与金标准诊断符合率高于拟诊LSIL的符合率,差异有统计学意义(χ~2=60.17,P0.01);另图像宫颈浸润癌漏诊2例。342例患者中除6例诊断为宫颈浸润癌者住院治疗外,另336例均于门诊随访,其中术后出血需处理者32例(9.36%),术后3个月复查TCT提示为意义不明的非典型鳞状上皮细胞(ASCUS)者3例(0.89%),术后6个月复查为高危型HPV阳性者2例(0.59%),LEEP术治愈331例,治愈率为98.51%。结论:充分阴道镜检查患者宫颈活检诊断宫颈病变准确率高,仍提倡对其采用传统"三阶梯"法诊治;不充分阴道镜检查患者宫颈活检诊断准确率低,充分阴道镜检查图像拟诊HSIL符合率高且易漏诊宫颈浸润癌,建议综合患者年龄、生育要求等因素考虑是否直接行LEEP术。两者联合应用,提高宫颈病变诊断准确率,防止过度诊治,减少患者就诊次数,减轻患者思想负担。     

宫颈低级别鳞状上皮内病变宫颈锥切术后病理升级的相关因素分析

目的 探讨宫颈低级别鳞状上皮内病变（LSIL）宫颈锥切术后病理升级的发生率及其相关影响因素。方法 纳入2014年1月至2022年4月于潍坊医学院附属医院因活检病理提示宫颈LSIL有指征行宫颈锥切的患者97例,分为病理升级组和病理未升级组进行分析。结果 97例患者中,54例（55.7%）宫颈锥切术后病理升级,两组一般资料、术前及术后人乳头瘤病毒（HPV）感染、宫颈液基细胞学（TCT）、阴道镜检查结果、累及腺体及锥体高度等比较,差异均无统计学意义（P>0.05）。将危险因素组合后行卡方检验显示,HPV16/18阳性伴TCT高级别鳞状上皮内病变（HSIL）/不排除高级别鳞状上皮内病变不典型鳞状细胞（ASC-H）或不典型腺上皮细胞（AGC）是宫颈锥切术后病理升级的危险因素（P=0.041）。结论 HPV16/18型阳性伴TCT>LSIL(HSIL/ASC-H/AGC)是影响活检LSIL术后病理升级的影响因素,对LSIL患者进行分流管理时需同时考虑患者术前HPV及TCT结果。LSIL宫颈锥切术后病理是否升级不影响患者术后HPV转归情况。

Usefulness of human papilloma virus testing in the screening of cervical cancer precursor lesions: a retrospective study in 314 cases

OBJECTIVE: To assess the usefulness of human papilloma virus (HPV) typing for predicting pre-malignant and malignant cervical lesions. STUDY DESIGN: 314 women, who underwent colposcopy, biopsies and high and low-risk HPV typing after a confirmed abnormal routine Pap test were studied. HPV-DNAs were typed by using PCR technique. RESULTS: We found a significant increasing rate of high-risk-HPV by the increasing severity of histology, ranging from 40% in negative cases to 86.9% in those with CIN3 lesions. The positive predictive value of high-risk-HPV ranged from 13.3% in patients with atypical squamous cells of undetermined significance (ASCUS) to 29.4% in those with HSIL. By contrast, negative predictive value was 96% in patients with ASCUS, 97.2% in low-grade squamous intraepithelial lesions (LSIL), and 71.4% in high-grade squamous intraepithelial lesions (HSIL). Sensitivity and specificity for detecting CIN2 or CIN3 was 86.0% and 41.3%, respectively. CONCLUSIONS: The high negative predictive value of high-risk HPV testing suggests that HPV negativity could be used for predicting the absence of important cervical lesions, and therefore avoiding unnecessary colposcopy in ASCUS and LSIL cases.     

CIN in pregnancy: antepartum and postpartum cytology and histology

OBJECTIVE: To determine the rates of antepartum and postpartum cervical intraepithelial neoplasia (CIN) 2 or worse in pregnant women with abnormal cervical cytology. STUDY DESIGN: A prospective, cohort study of 283 pregnant women referred for colposcopy between 1992 and 1999 for the evaluation of abnormal Pap smears. In this analysis, the population was stratified by severity of referral cytology (atypical squamous cells of undetermined significance [ASCUS] or low grade squamous intraepithelial lesion [LSIL] versus high grade squamous intraepithelial lesion [HSIL] and atypical glandular cells of undetermined significance [AGUS]). RESULTS: Sixty-seven women (24%) had ASCUS, 147 (52%) LSIL, 67 (24%) HSIL and 2 (0.7%) AGUS. As compared to women with HSIL or AGUS, women with ASCUS or LSIL were less likely to undergo antepartum biopsy (relative risk [RR] .34, 95% CI .23-.51) and if biopsied, less likely to have CIN 2 or worse (OR .49, 95% CI .24-.99). Women with antepartum ASCUS or LSIL were less likely to have postpartum HSIL (OR .29, 95% CI, .17-.52) and tended to have fewer histologically severe biopsies as compared to women with antepartum HSIL (OR .55, 95% CI .31-1.05). CONCLUSION: Among those biopsied, pregnant women with mildly abnormal cytology (ASCUS or LSIL), as compared to pregnant women with HSIL, were less likely to have either antepartum or postpartum CIN 2 or worse.     

Cervical intraepithelial neoplasia in adolescent women: incidence and treatment outcomes

OBJECTIVE: We sought to estimate the incidence of cervical intraepithelial neoplasia (CIN) and treatment outcomes in adolescents with abnormal cytology. METHODS: Adolescent women (ages 14-21 years) referred to colposcopy clinic for abnormal cytology from 1992 to 2004 were identified by computerized database. Only adolescents with biopsy-proven CIN were evaluated. Demographic and risk factor data were obtained from medical records. Referral cytology, histology on biopsy and loop electrosurgical excisional procedure (LEEP), and follow-up cytology were analyzed and compared. Statistical analysis was performed by chi(2) or Fisher exact test, Student t tests, and logistic regression. RESULTS: Of 1,678 adolescents, 517 had biopsy-proven CIN and follow-up. Seventy-seven patients were referred with atypical squamous cells of undetermined significance (ASCUS) cytology; 174 patients were referred with low-grade squamous intraepithelial lesions (LSIL), 258 with high-grade squamous intraepithelial lesions (HSIL) and eight with atypical glandular cells (AGC). The rate of CIN 2/3 in patients with ASCUS, LSIL, and HSIL was 35% (95% confidence interval 24-46%), 36% (29-43%), and 50% (44-56%), respectively. A total of 192 patients with biopsy-proven CIN 2/3 underwent a LEEP. No patients were diagnosed with cervical carcinoma. Fifty-five percent (95% confidence interval 48-62%) of patients had abnormal cytology on follow-up, suggesting recurrence or reinfection. CONCLUSION: Adolescents with abnormal cytology have a high incidence of CIN2/3 and high rates of abnormal cytology after LEEP. Cervical intraepithelial neoplasia 2/3 is common in adolescents with abnormal cytology, yet no cases of cancer were identified. Importantly, LEEP fails to meet its therapeutic goals given a high incidence of abnormal follow-up cytology and may represent overly aggressive therapy because the majority of human papillomavirus infections are transient with high regression rates.

宫颈巴氏涂片与LCT在低收入妇女妇科普查中的应用

目的探讨宫颈巴氏涂片与液基细胞学（LCT）在低收入已婚妇女宫颈癌筛查中的应用价值。方法2008年1月至6月上海市浦东新区妇幼保健院对所在社区6416例低收入已婚妇女（低收入组）采用宫颈巴氏涂片进行了宫颈癌筛查,其中322例同期行LCT,并与同期来上海市浦东新区妇幼保健院做宫颈癌筛查行LCT的294名妇女进行对照（对照组）。结果①宫颈刮片巴氏异常者（≥Ⅱb级）低收入组中22例（0．34％）,其中Ⅱb级12例（0．19％）,Ⅲ级10例（0．16％）,无Ⅳ级及Ⅴ级。15例（Ⅱb5例,其余Ⅲ级）行阴道镜下活检,病理结果CIN8例,其中CIN12例,CIN2和CIN3各3例;②低收入组同期行LCT的322例妇女中,细胞学≥ASCUS共41／322例（12．73％）,其中ASCUS15例,HSIL 1例,行阴道镜下活检病理结果CIN5例（CIN1和CIN2各2例,CIN31例）;HSIL1例为子宫颈鳞状细胞癌。对照组：细胞学≥ASCUS 22／294例（7．48％）。其中ASCUS 11例行阴道镜下活检。病理结果仅CIN 21例;2例LSIL;1例为CIN2。两组AGC各1例经阴道镜下活检均无异常;③低收入组中322例行宫颈刮片和LCT做自身对照：315例巴氏均为Ⅰ级,LCT正常;巴氏Ⅱb级2例,LCT均为ASCUS,病理分别为CIN1和CIN2;巴氏Ⅲ级3例,LCT检查,其中2例为ASCUS,阴道镜活检仅1例病理为CIN2。结论宫颈细胞学是筛查宫颈病变的有效手段,巴氏涂片法在基层对低收入人群仍可为主要筛查方法。有条件者可采用LCT,以提高宫颈疾病筛查的敏感性。     

液基薄层细胞学ASCUS发生宫颈高级别上皮内病变的高危因素分析

目的探讨宫颈细胞学不能明确意义的非典型鳞状细胞(ASCUS)发生宫颈高级别上皮内病变(HSIL)及以上的高危因素。方法选取2018年7月至2019年11月就诊于郑州大学人民医院妇科的1074例患者,患者宫颈液基细胞学为ASCUS、高危型人乳头瘤病毒(HPV)阳性,且均行阴道镜检查+宫颈活检术,统计分析患者的临床资料。结果1074例患者中,宫颈癌13例(1.21%),HSIL 180例(16.76%),LSIL 275例(25.61%),慢性炎症606例(56.42%)。单因素分析结果显示,≥HSIL组与≤LSIL组的高危型HPV16/18阳性、绝经、孕次及流产次数比较,差异均有统计学意义(P<0.05)。多因素分析结果显示,HPV16/18阳性、绝经、孕次>2次、流产次数≥2次均为ASCUS发生HSIL及以上的高危因素。结论HPV16/18阳性、绝经、孕次>2次、流产次数≥2次是ASCUS发生HSIL及以上的高危因素。     

Prospective follow-up suggests similar risk of subsequent cervical intraepithelial neoplasia grade 2 or 3 among women with cervical intraepithelial neoplasia grade 1 or negative colposcopy and directed biopsy

OBJECTIVE: The purpose of this study was to determine the risk of cumulative cervical intraepithelial neoplasia (CIN) grade 2 or 3 according to initial colposcopy and directed biopsy results among women with low-grade squamous intraepithelial lesions (LSIL) or human papillomavirus (HPV) DNA positive atypical squamous cells of undetermined significance (ASCUS). STUDY DESIGN: A 2-year follow-up of 897 cases of LSIL and 1193 cases of HPV DNA positive ASCUS from the ASCUS/LSIL Triage Study was used to simulate American Society for Colposcopy and Cervical Pathology Consensus Conference recommendations. Women with CIN grade 1 or less were followed up for 2 years by semiannual cytologic examination, with universal exit colposcopy. The clinical end point was a cumulative clinical center histologic diagnosis of CIN grade 2 or 3. RESULTS: The cumulative risk of CIN grade 2 or 3 was equivalent for LSIL (27.6%) and HPV positive ASCUS (26.7%). After excluding the women with a diagnosis of CIN grade 2 or 3 at initial colposcopy and directed biopsy (17.9%), the remaining women were at nearly identical risk for subsequent CIN grade 2 or 3 regardless of initial colposcopy result (completely negative colposcopy-11.3%; negative colposcopically directed biopsy-11.7%; and CIN grade 1 biopsy-13.0%). CONCLUSION: LSIL and HPV positive ASCUS are clinically equivalent. Initial colposcopic detection of obviously prevalent CIN grade 2 or 3 reduces risk. However, for the remaining women who have CIN grade 1 or less on colposcopy and directed biopsy, the risk for subsequent CIN grade 2 or 3 (whether missed, prevalent, or truly incident) is approximately 12% over 2 years. This risk does not vary meaningfully by initial distinction of histologic CIN grade 1 from negative colposcopy and biopsy.     

Situation analysis of atypical squamous cells of undetermined significance smears in Songklanagarind Hospital

OBJECTIVE: To review the incidence, management, follow-up rate and colposcopic diagnosis of atypical squamous cells of undetermined significance (ASCUS) detected on cervical smears in Songklanagarind Hospital, Thailand. METHODS: A retrospective study of ASCUS smears taken during January 2000 to March 2001 at Songklanagarind Hospital was performed. The type of management was classified and the follow-up rate was detected. Cases with colposcopy, tissue biopsy, endocervical curettage, conization and hysterectomy specimen were reviewed. In the cases without tissue biopsy, the final diagnoses were based on the colposcopic examination. RESULTS: Among the 25068 Pap smears examined, the incidence of ASCUS was 0.62%. Of these, only 56.13% received the further evaluation. The non-compliance rate was 18.71%. The incidences of cervical intraepithelial neoplasia (CIN) and invasive cancer among the cases who received colposcopy were 15.96% and 2.13%, respectively. The incidence of CIN or invasive cancer in ASCUS favor reactive and ASCUS favor neoplasia were not different statistically significant. CONCLUSIONS: Management of ASCUS smears by follow-up may be inappropriate. A practice guideline which consists of active management, intensive follow-up system and well-organized data management should be used to improve the situation.
