Analysis of cervico-vaginal (Papanicolaou) smears,in girls 18 years and under

This study was conducted retrospectively at the Queen Elizabeth Hospital and a private laboratory in Barbados to determine the types of epithelial abnormalities in cervico-vaginal Papanicolaou (Pap)-stained smears, and their clinical implications in Barbadian girls, 18 years and under, during the five-year period January 1995 to December 1999. Two hundred and sixty-five Pap smears from 236 patients were examined and the gynaecological history, initial and repeat Pap smear diagnoses, and histology reports of these patients were analyzed. Of the 236 first-visit smears, 94 (39.8%) were abnormal with 36 (15.3%) displaying cytologic features of squamous intra-epithelial lesions (SIL), (33 low grade and 3 high grade). A diagnosis of atypical squamous cells of undetermined significance (ASCUS) was reported in the remaining 58 (24.5%) abnormal smears, of which 35 (60.3%) were suspected to be related to human papillomavirus (HPV) infection. Twenty-two (23.4%) of these 94 patients, who had abnormal smears of either ASCUS or low grade squamous intra-epithelial lesions (LSIL) were re-evaluated within six to twelve months of the initial abnormal Pap smear diagnosis. Eight of these 22 patients (36.4%) had histological diagnosis of LSIL inclusive of cervical intra-epithelial neoplasia grade 1 (CIN 1) and condylomata. High-risk HPV DNA types were detected in two of these eight patients (25%). The study confirms that sexually active teenage girls are at risk of developing SIL and high-risk HPV infection. Screening of sexually active teenaged girls by Pap smears followed by other appropriate investigative procedures is recommended.     

Identifying women with cervical neoplasia: using human papillomavirus DNA testing for equivocal Papanicolaou results

CONTEXT: A Papanicolaou (Pap) test result of atypical squamous cells of undetermined significance (ASCUS) presents a clinical challenge. Only 5% to 10% of women with ASCUS harbor serious cervical disease, but more than one third of the high-grade squamous intraepithelial lesions (HSILs) in screening populations are identified from ASCUS Pap test results. OBJECTIVE: To determine whether human papillomavirus (HPV) DNA testing of residual material from liquid-based Pap tests and referral of cases found to be HPV-positive directly to colposcopy could provide sensitive detection of underlying HSILs in women with ASCUS Pap results, compared with repeat Pap testing. DESIGN AND SETTING: Natural history of women with ASCUS Pap smear results, all of whom had liquid-based cytology, HPV testing, and subsequent repeat Pap tests and colposcopy with histologic evaluation, conducted at 12 gynecology clinics in a large managed care organization between October 1995 and June 1996. PARTICIPANTS: From a cohort of 46009 women who had routine cervical examinations, 995 women with Pap test results of ASCUS who consented to participate were identified. MAIN OUTCOME MEASURES: Cervical histology, HPV test results, and repeat Pap smear results, and sensitivity of HPV testing to identify patients found to have HSIL+ histology. RESULTS: Of 995 participants with ASCUS Pap test results, 973 had both a definitive histologic diagnosis and HPV result. Sixty-five (6.7%) had histologic HSIL or cancer. For women with histologic HSIL+, the HPV test was positive in 89.2% (95% confidence interval [CI], 78.4%-95.2%), and the specificity was 64.1 % (95% CI, 60.9%-67.2%). The repeat Pap smear result was abnormal in 76.2% (95% CI, 63.5%-85.7%). Triage based on HPV testing only or on repeat Pap testing only would refer similar proportions (approximately 39%) to colposcopy. The sensitivity of HPV DNA testing for HSIL was equivalent to, if not greater than, that of the repeat Pap test. We further estimated that an HPV-based algorithm including the immediate colposcopy of HPV-positive women, and then repeat Pap testing of all others, would provide an overall sensitivity of 96.9% (95% CI, 88.3%-99.5%). CONCLUSIONS: For women with ASCUS Pap tests, HPV DNA testing of residual specimens collected for routine cervical cytology can help identify those who have underlying HSIL. By testing the specimen collected at initial screening, the majority of high-risk cases can be identified and referred for colposcopy based on a single screening.     

Correlation of cervical cytology with cervical histology

OBJECTIVE: To correlate cervical cytology with Cervical histology. METHODOLOGY: A hospital based prospective study was carried out in consecutive total forty-three patient attending oncology clinic of Kathmandu Medical College Teaching Hospital, Sinamangal, Nepal from 1st Bhadra 2061 to end of Falgun 2061 (18th August 2004-12th February 2005) during authors posting in this clinic. All patients who underwent cervical biopsy on either indication of clinically suspected lesions or abnormal cytology were correlated with Pap smear report. Pap smear was carried out in conventional technique using Ayre's spatula. Cervical biopsy was carried out with help of punch biopsy forceps in operation Theatre without the guidance of colposcopy. All pertinent information regarding patient profile in terms of their age, parity, age at marriage, age at 1st child birth, smoking habit, contraceptive use, and symptom of vaginal discharge was taken. Reports of Pap smear and cervical biopsy of these patients were collected from oncology clinic during their follow up visit and all these information and finding were entered in structured questionnaire. The reporting of Pap smear was done in Bethesda system. The average duration between performing Pap smear and biopsy was of one month. Statistical analysis was carried out by EPI-INFOS6 system. RESULT: Of forty three patients who underwent cervical cytology 22 cases were of Benign lesion, 8 cases of LSIL, 9 cases of HSIL, 3 cases of invasive carcinoma and 1 of ASCUS. Sensitivity, specificity, positive predictive value, negative predictive value, diagnostic accuracy and p-value in benign grade was 76%, 83.3%, 86.4%, 71.4%, 79.1%, 0.0004 respectively. Similarly sensitivity, specificity, positive predictive value, negative predictive value, diagnostic accuracy and p-value in LSIL was 60%, 93.9%, 75%, 88.6%, 86%,0 .0008 respectively. For HSIL it was 100%, 89.5%, 55.6%, 100%, 90.7 0.0001 respectively. Respectively for carcinoma it was 100% for sensitivity, specificity, positive predictive value, negative predictive value, diagnostic accuracy p-value was 0.00008. CONCLUSION: Pap smear significantly correlated with cervical histology.

Comparing the results of Pap smear and Direct Visual Inspection (DVI) with 5% acetic acid in cervical cancer screening

Background:

Cervical cancer is the most second common cancer among Iranian women. This study was carried out to compare the results of Pap smear method and Direct Visual Inspection (DVI) with 5% acetic acid in cervical cancer screening in Tabriz, Iran.

Material and Methods:

This cross-sectional study was carried out in Alzahra Therapeutic-Educational Centre, Tabriz, Iran in 2013 on 1000 women. First, Pap smear was done for all women, and then the cervix exposed with 5% acetic acid by cotton swab for 30 seconds and observed under adequate light. At the end, women with abnormal results in Pap smear or DVI method were referred to colposcopy and biopsy. Test''s sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV), LR+, LR- and confidence interval (CI) were determined (P < 0.05).

Results:

Nine-hundred and seventy-four (94.7%) cases were normal and had no abnormal findings and 26 (2.6%) participants had positive results in Pap smear or DVI test. Twelve women had abnormal Pap smear (nine women with atypical squamous cells of undetermined significance, ASCUS, three women with dysplasia, atypical endocervical, and low-grade squamous intraepithelial lesion, LSIL results) and 14 women had positive DVI (four women with human papillomavirus, HPV or koilocyte,) and one women with abnormality in both method had carcinoma in biopsy that referred to oncologist. In this study the sensitivity, specificity, PPV and NPV for DVI were 71.4%, 50%, 35.7%, and 81.8% respectively in comparison with 14.3%, 50%, 10%, and 60% for Pap smear.

Conclusion:

As the DVI method has higher sensitivity and positive predictive value than Pap smear, it could be used as a useful method beside the Pap smear.

Age-specific prevalence of human papillomavirus by grade of cervical cytology in Tibetan women

Background Human papillomavirus （HPV） is believed to be the most common sexually transmitted infection. However,little is known about the prevalence and distribution of HPV types in China. We aimed to assess the prevalence and the distribution of HPV types as well as risks for abnormal cervical cytology in women who reside in the Tibetan Autonomous Region of China.Methods A cross-sectional study was performed involving a sample of 3036 women. An epidemiological questionnaire was applied and cervical specimens were obtained for liquid-based cytology and HPV DNA detection. Statistical analysis included chi-square and Logistic regression model.Results In this population, 3.66% （111/3036） had atypical squamous cells of undetermined significance （ASCUS）,1.45% （44/3036） low-grade squamous intraepithelial lesions （LSIL） and 1.09% （33/3036） had high-grade squamous intraepithelial lesions （HSIL）. Tibetan women （5.74%, 137/2387） exhibited lower abnormal cytology rates than non-Tibetan women （8.01%, 52/649, P=0.03）. The overall prevalence of HPV infection was 9.19% （279/3036）. We failed to identify any differences in HPV prevalence by age. In the groups with normal, ASCUS, LSIL and HSIL, the overall HPV prevalences were 7.41% （211/2847）, 24.32% （27/111）, 56.82% （25/44） and 45.45% （15/33）, respectively. HPV 16 （1.52%,46/3036） was the most common type, and was also the most prevalent in women with ASCUS （8.11%, 9/111） and HSIL （15.15%, 5/33）. The most common HPV type for Tibetan women was HPV 16 （1.42%, 34/2387）, whereas for non-Tibetan individuals it was HPV 33 （2.31%, 15/649）. Of the 279 HPV-infected women, 40 individuals （14.34%） presented with multiple HPV positivity. Women who had two pregnancies were more likely to have abnormal cytology smear （OR=1.67;95% CI： 1.07-2.61）.Conclusions A low prevalence of HPV positivity was observed in women who reside in the Tibetan Autonomous Region of China. The prevalence of abnormal cervical cytology and HPV type distributions were different between Tibetan and non-Tibetan women.

目的：了解内蒙古中西部地区宫颈癌及宫颈癌前病变的发病情况及流行病学特征。方法：对内蒙古中西部地区66 981例妇女进行薄层液基细胞学技术检测,采用TBS细胞学分类诊断,将诊断意义不明的不典型鳞状上皮细胞（ASCUS）以上病变均列为阳性病例,并进行阴道镜下多点取材活检,以病理学结果为标准,将细胞学检测结果与活检结果作对比分析。分析各年龄组人群宫颈病变的发病规律及蒙汉族妇女宫颈病变的发病趋势。结果：薄层液基细胞学检测（TCT）法标本满意率为99.9%（66911/66981）,细胞阳性病例5466例,总检出率8.17%（5466/66911）。检出癌（CA）47例（占0.07%）;高度鳞状上皮内病变（HSIL）301例（占0.45%）;低度鳞状上皮内病变（LSIL）871例（占1.30%）;不除外高度鳞状上皮内病变的不典型鳞状细胞（ASC-H）635例（占0.95%）;ASCUS＋AGUS共3612例（占5.40%）。取其中5123例与阴道镜下活检结果比较,宫颈癌和癌前病变的病理阳性率和准确率分别是CA（100%,100%）;HSIL（97.83%,90.58%）;LSIL（93.07%,59.34%）;ASC-H（72.79%,40.18%）;ASCUS＋AGUS（37.69%,37.69%）。经比较蒙古族妇女宫颈病变的发病率高于汉族妇女。不同年龄妇女宫颈病变发病情况有所不同。结论：①TCT技术和TBS系统能较准确地反映宫颈癌和癌前病变。②TCT技术适用于宫颈病变的大规模筛查,3阶梯诊断能明显提高宫颈病变的检出率。③宫颈癌及癌前病变发病率于年龄呈正相关。④内蒙古中西部地区蒙古族妇女宫颈癌及癌前病变患病率高于汉族妇女。⑤筛查是预防和控制宫颈癌的主要手段。
