目的探讨2013年北京市宫颈癌免费筛查获得的宫颈细胞学阅片的质量控制情况,并进行相关分析。 方法自2013年在北京市16个区、县宫颈癌筛查机构接受宫颈癌免费筛查获取的286 781张宫颈涂片信息中,采用概率随机抽样法,随机抽取9 907张宫颈涂片进行质量控制结果分析。本研究以专家阅片结果作为宫颈细胞学诊断金标准,对传统巴氏涂片及液基细胞涂片的宫颈细胞学检出阳性率差异、各质量控制指标差异及涂片不满意率差异等进行统计学比较。 结果①液基细胞涂片的总检出阳性率、低度鳞状上皮内瘤变(LSIL)及高度鳞状上皮内瘤变(HSIL)的检出阳性率均较巴氏涂片高,且差异有统计学意义(2.41% vs 2.05%,χ2=39.885,P=0.000;0.58% vs 0.31%,χ2=113.772,P=0.000;0.14% vs 0.11%,χ2=4.464,P=0.035)。②抽取进行质量控制结果分析的涂片中,巴氏涂片与液基细胞涂片的假阴性率、特异度及符合率比较,差异均无统计学意义(P>0.05);巴氏涂片假阳性率较液基细胞涂片低,而其灵敏度较液基细胞涂片高,且差异均有统计学意义(0 vs 0.55%,χ2=18.342,P=0.000;100.00% vs 75.00%,χ2=98.980,P=0.000)。③本组宫颈涂片中,涂片不满意率为4.17%(413/9 907),首要原因为染色偏浅和(或)结构不清(54.24%);其次为细胞量不足(43.09%)。因细胞量不足导致的不满意率,巴氏涂片较液基细胞涂片高(2.45% vs 1.44%),而因染色偏浅和(或)结构不清导致的不满意率,则为液基细胞涂片较巴氏涂片高(3.34% vs 0.26%),且差异均有统计学意义(χ2=12.452,93.311;P=0.000)。 结论北京市宫颈癌免费筛查的宫颈细胞学检出阳性率有待进一步提高。建立完善的宫颈细胞学质量控制评价系统,对涂片的取材、制片及染色等环节加以控制,以提高涂片满意度及宫颈细胞学阅片质量。 相似文献

一百多年前,子宫颈糜烂被描述为因炎症导致宫颈表层上皮脱失的一种宫颈形态。近现代观为:子宫颈糜烂是指位于宫颈外口的原始柱状上皮或早-中期的化生上皮,因雌激素影响,宫颈管内柱状上皮延伸至宫颈管外口,形成临床所见宫颈异位或外翻的典型外观。子宫颈糜烂曾被视作宫颈浸润癌的高危因素。现公认高致癌型人乳头瘤病毒(human papilloma virus,HPV)感染是发生宫颈浸润癌的核心因素。子宫颈糜烂与子宫颈癌的发生无关,对其治疗属过度医疗行为,应予以制止。 相似文献

3 women with only mild changes in cervical smears were later found to be suffering from cervical adenocarcinoma. The first patient was 53 years old. Her smears repeatedly showed Pap 3 with moderately atypical glandular cells. After 3 colposcopic examinations with biopsies and 2 loop electrosurgical excision procedures of the cervix which showed no histological signs of malignancy, diagnostic conization revealed an adenocarcinoma of the endocervix. She underwent a radical hysterectomy and chemoradiation because of positive pelvic nodes. The second patient was 30 years old and had persistent vaginal discharge and an enlarged cervix, but no cytological abnormalities. Colposcopy was unsatisfactory and the tissue obtained by loop electrosurgical excision was normal. Adenocarcinoma was diagnosed after conization. She was treated with radical hysterectomy and radiotherapy but died after one year. The third patient, aged 26, had a long history of slightly abnormal Pap smears and vulvar condylomata, and was referred with vaginal discharge. A severe abnormal smear with glandular atypia was followed by colposcopical biopsies and conization, which revealed an endocervical adenocarcinoma. She underwent radical hysterectomy. Adenocarcinoma is a rare type of cervical cancer: III cases out of 584 patients with cervical cancer in 2003 in the Netherlands. This neoplasm is more difficult to detect than cervical squamous cell carcinoma. Cervical cytology is not an effective tool for screening and diagnosis. Due to the localization, multifocality and diversity in its presentation, the assessment of cytology has a high false-negative percentage. Screening may be enhanced by combining cytology with testing for high-risk HPV types, notably type 18. If cervical cytology shows persistent atypical glandular cells with no conclusive histological result, then due to the endocervical localisation of the lesions adenocarcinoma can only be excluded by conization. 相似文献

Recent Dutch and non-Dutch studies have shown that the absence of endocervical cells (ecc-) in an adequate cervical smear does not present an increased risk for the presence or occurrence of cervical cancer or premalignant abnormalities in a later phase. Based on these findings, the Coordination Committee Cervical Cancer Screening of the Dutch Health Insurance Council had advised dropping the repeat advice for non-abnormal ecc- smears by January 1st 2002. The National Health Insurance Council has agreed to this advice. The following measures have been taken: (a) no repeat advice for ecc- smears; in the case of negative findings the woman waits until the next five-yearly invitation from the screening programme; (b) whether the portio cervicis was seen has to be stated on the national request form; (c) the reporting of an ecc- in the cytology report and periodical feedback to general practitioners remains unchanged; (d) in the case of a non-abnormal ecc- smear with an uninspected portio or doubts as to whether the transformation zone was adequately scraped, either the smear will have to be repeated or the patient will have to be referred to the gynaecologist. 相似文献

Abstract: We established a culturally appropriate, community-based women's health service in Yuendumu, Northern Territory, to improve women's health and to remedy the low rate of cervical screening. During the 16 months of the program 419 cervical smears were taken, increasing coverage of the women eligible from 51 to 78 per cent Acceptance of the program was excellent, with only 2 per cent of the women approached refusing to have a smear. Over 70 per cent of the Pap smears were done by the nursing staff in the clinic; quality control was good, with 9 per cent of smears reported as having no endocervical cells. Sixty-four per cent of screened women had normal smears and 0.9 per cent showed evidence of cervical intraepithelial neoplasia (CIN). Three women were referred for treatment of CIN, two for CIN I and one for CIN III. The program illustrates how a combination of community involvement, staff stability, teamwork, and cross cultural understanding can achieve a comprehensive and successful cervical screening service in a remote Aboriginal community. 相似文献

BACKGROUND: Few data are available on factors associated with the quality of Papanicolaou smears performed in primary care. OBJECTIVE: To identify the patterns and proficiency of cervical cancer screening among different primary care specialties. MATERIALS AND METHODS: Clinical and cytologic data from 21,833 Papanicolaou smears, submitted to a single large commercial laboratory by 176 clinicians during a 7-month period, were correlated with individual clinician and specialty characteristics according to indexes of specimen quality. RESULTS: Obstetrician-gynecologists, nurse practitioners, and physician assistants provided screening to a younger population of women compared with family physicians, internists, and general practitioners. Factors positively associated with a greater probability of a "satisfactory" smear or the presence of endocervical cells (as a marker of adequate sampling) were increasing patient age, use of the cytobrush, and the specialty of the obstetrician-gynecologist. Satisfactory smears were not associated with any increased identification of cytologic abnormalities compared with "limited" smears. In contrast, smears with endocervical cells showed a higher proportion of abnormalities compared with specimens without such cells. CONCLUSIONS: Differences in the performance of obtaining Papanicolaou smears exist between primary care specialties, but need further clarification. The use of the cytobrush and the presence of endocervical cells are criteria that reflect clinician proficiency more realistically than the laboratory criterion of satisfactory smear. 相似文献

BACKGROUND. The Cervex-Brush (Rovers, The Netherlands; Unimar, Wilton, Conn) is a cervical cytologic sampling device used to simultaneously collect endocervical and ectocervical cells. The optimal method for using this device to collect cervical epithelial cells for a Papanicolaou smear has not been described in the medical literature. METHODS. Using the Cervex-Brush, Papanicolaou smears were collected from 516 women in a prospective randomized study to evaluate five different clockwise rotation techniques: 180 degrees rotation of the brush, 360 degrees, 720 degrees, 1080 degrees, and 1800 degrees. The Bethesda System of classifying Papanicolaou smears was used to report cytologic results. Endocervical cell presence as an indicator of smear adequacy was quantitated from 0 to 4+. RESULTS. As the number of rotations was increased, the number of endocervical cells collected also increased (P less than .05). Abnormal epithelial cells were found in 22.3% of the smears obtained by rotating the brush 1080 degrees and 1800 degrees. This was compared with abnormal cells found in 8.2%, 4.5%, and 11.5% of the smears collected by rotating the brush 180 degrees, 360 degrees, and 720 degrees, respectively (P less than .001). Two smears that identified high-grade squamous intraepithelial lesions were collected using the 1800 degrees rotation. Unsatisfactory smears were obtained in 39 (7.5%) of the 516 smears. The percentage of slides containing hemorrhagic artifact was greatest (16.4%) in the 1800 degrees rotation group, but the likelihood of the Papanicolaou smear being considered unsatisfactory was not increased (P less than .05). CONCLUSIONS. Using a clockwise 1800 degrees rotation of the Cervex-Brush to obtain a Papanicolaou smear maximized the collection of endocervical cells, detected the greatest percentage of abnormal cells, and did not statistically exceed the acceptable limit for hemorrhagic artifact. 相似文献
