Undetermined Significance

Context.—Previous work has reported that most high-grade cervical neoplasia is seen in patients with preceding Papanicolaou test results of atypical squamous cells of undetermined significance. This information was based on conventional test results and the Bethesda 1991 reporting system and was determined before the current treatment guidelines. Objective.—Our objective was to perform a retrospective review of all histologically confirmed, high-grade cervical neoplasia to determine the diagnosis of the preceding liquid-based Papanicolaou test. Design.—A total of 189 histologically confirmed, high-grade cervical intraepithelial neoplasia (CIN) cases grade 2 and greater were identified for a 1-year period. Results.—Of the 189 cases, 10 (5.3%) had a previous diagnosis of atypical squamous cells of undetermined significance; 55 (29.1%) had low-grade squamous intraepithelial lesions; 31 (16.4%) had low-grade squamous intraepithelial lesions, unable to rule out a high-grade squamous intraepithelial lesion; 21 (11.1%) had atypical squamous cells, unable to rule out a high-grade squamous intraepithelial lesion; 68 (36%) had high-grade squamous intraepithelial lesions; 1 (0.5%) had atypical glandular cells; 1 (0.5%) had adenocarcinoma in situ; and 2 (1%) had invasive carcinoma. Combined “low grade” Papanicolaou test results (atypical squamous cells of undetermined significance and low-grade squamous intraepithelial lesion) preceded 51 of 103 cases of CIN 2 (49.5%) and 14 of 103 cases (13.6%) of CIN 3/cancer, whereas “high grade” Papanicolaou test results (atypical squamous cells, unable to rule out a high-grade squamous intraepithelial lesion; low-grade squamous intraepithelial lesions, unable to rule out a high-grade squamous intraepithelial lesion; high-grade squamous intraepithelial lesions; atypical glandular cells; adenocarcinoma in situ; and invasive carcinoma) preceded 52 of 103 CIN 2 cases (50.5%) and 72 of 103 CIN 3/cancer cases (69.9%). Conclusions.—Our data show that we can now more-reliably predict high-grade dysplasia on routine Papanicolaou tests. Only a small fraction of histologically confirmed CIN 2/3 cases are found following a Papanicolaou test diagnosis of atypical squamous cells of undetermined significance.

Objective To evaluate the association of age at first sexual intercourse with the results of the cervicovaginal cytology. Study Design Observational analytical study about the prevalence of altered cervicovaginal cytology results in women aged between 18 and 34 years from a densely populated area in Brazil, during 10 years. The patients were stratified into 2 categories according to their age at first sexual intercourse (13–16 years and 17–24 years). Results From the total of 2,505,154 exams, 898,921 tests were in accordance with the inclusion criteria. Considering women with 4 years or less from the first sexual intercourse as a reference, those with 5 to 9 years and 10 years or more showed a higher prevalence of high-grade squamous intraepithelial lesions (HSILs). Women with an earlier onset of sexual intercourse (13–16 years) showed higher prevalence ratios for atypical squamous cells (ASC), low-grade squamous intraepithelial lesion (LSIL) and HSIL. The prevalence ratio for HSIL adjusted by age at diagnosis and by age at first sexual intercourse was higher only for women with an earlier onset of sexual intercourse. Conclusions The age of first sexual intercourse could be a variable that might qualify the selection among young women who are really at a higher risk for HSIL.

Abstract Background The effectiveness of surgery of high-grade squamous intraepithelial lesion in post-menopausal women needs to be investigated. This study evaluated the clinical significance of cold-knife conization in the diagnosis and surgery of cervical high-grade squamous intraepithelial lesions in post-menopausal women. Methods We conducted a retrospective analysis of post- and pre-menopausal patients with high-grade squamous intraepithelial lesion. All patients received cold-knife conization as the primary therapy. Results The satisfactory rate of colposcopy was significantly lower in the post-menopausal group than in the pre-menopausal group (38.33 vs. 71.25%; χ2 = 36.202, P < 0.001). The overall positive margin rate of cold-knife conization (25.83 vs 12.50%; χ2 = 10.106, P = 0.001) and rate of positive endocervical cone margins (16.67 vs. 4.58%; χ2 = 14.843, P < 0.001) were significantly higher in the post-menopausal group. Moreover, 49 post- and 60 pre-menopausal women underwent subsequent surgical treatment (40.83 vs. 25.00%). Residual rate of positive and negative margins in patients before and after menopause was significantly different (χ2 = 5.711, P = 0.017; χ2 = 12.726, P < 0.001, respectively). The recurrence rate in post-menopausal women remained 3.85%. Conclusions Cold-knife conization can be performed as a primary procedure for diagnosis and surgery of post-menopausal patients with high-grade squamous intraepithelial lesions. Sufficient deep excisions are necessary to avoid positive endocervical margins, which can reduce the residual and recurrence of postoperative lesions.

Abstract Context.—Conventional Papanicolaou (Pap) test slides of high-grade squamous intraepithelial lesions (HSILs) that are frequently misdiagnosed are known to have relatively few dysplastic cells. Whether this is true of cases of HSIL in ThinPrep Pap Test specimens is not known. Objective.—To determine if cases of HSIL in ThinPrep specimens that are frequently missed have relatively few dysplastic cells. Design.—The cytologic features of 16 ThinPrep cases of HSIL that performed poorly in the College of American Pathologists Interlaboratory Comparison Program were compared with 22 ThinPrep Pap Test cases that performed extremely well. Results.—Significantly more cases that performed poorly had fewer than 250 dysplastic cells (13/16) than cases that performed well (3/22) (P &lt; .001). Conclusion.—ThinPrep Pap Test cases with a diagnosis of HSIL that performed poorly in this program had significantly fewer dysplastic cells than those that performed well.

Objective: We aimed to assess potential associations between atypical squamous cell (ASC) subgroups: ASC-US (undetermined significance) and ASC-H (cannot exclude high-grade squamous intraepithelial lesion), regarding cytomorphological features, high-risk (HR) human papillomavirus (HPV) testing, and histological outcomes in a sample of Brazilian women. Study Design: Cross-sectional study which evaluated 1,346 liquid-based cytologies between January 2010 and July 2016 with ASC results. ASC-US and ASC-H were analyzed for frequency, diagnostic criteria, and cytological findings and compared with HR-HPV tests and histological outcomes. Results: Enlarged nucleus was the most frequent ASC-US criterion, but alternative criteria were present in 20% of the total cases. No ASC-US criteria were associated with histological outcomes or HR-HPV positivity. Parakeratosis, corneal pearl, giant cells, and binucleation were strongly associated with ASC-US while hyperkeratosis was associated with high-grade squamous intraepithelial lesions (HSIL) or a superior outcome. HR-HPV was positive in 64.39% of ASC-US and 65.38% of ASC-H. HSIL or superior outcomes also occurred in 13.33% of ASC-US and 64.71% of ASC-H cases. Conclusion: Alternative criteria for ASC-US were relatively frequent. Reactive cellular changes suggestive of atypias were more abundant in ASC-US. Although ASC-H is associated with worse histological outcomes, no differences in HPV positivity were found in comparison to ASC-US.

Abstract Context.—Liquid-based preparations (LBPs) and human papillomavirus testing have led to changes in cervical cytology practices. The College of American Pathologists attempts to track practice patterns using a supplemental questionnaire, which allows laboratories to report diagnostic practices. Objective.—To analyze the 2006 reporting practices and to compare the results with the 2003 survey data. Design.—Questionnaire was mailed to 1621 laboratories. Participants included laboratories enrolled in the 2006 College of American Pathologists Gynecologic Proficiency Testing Program or the educational Interlaboratory Comparison Program in Gynecologic Cytology. Results.—Of the 679 responding laboratories (response rate, 42%), most (97.8%; n  =  664) had implemented the Bethesda 2001 terminology. The median rate for all preparations with low-grade squamous intraepithelial lesions was 2.5% (2.9% for LBPs) compared with a 2003 median rate of 2.1%; the increase was confined to LBPs. Rates for high-grade squamous intraepithelial lesions (median, 0.5%) and atypical squamous cells have changed little. High-grade squamous intraepithelial lesions and unsatisfactory rates varied at statistically significant levels between types of LBPs. Most atypical squamous cell cases were subclassified as undetermined significance (median, 4.3%). The median ratio of atypical squamous cells to squamous intraepithelial lesions and carcinomas for all specimen types combined was 1.5, similar to the 2003 median ratio of 1.4. The median rates for findings of squamous cell abnormalities for 2006 were significantly higher for LBPs than for conventional smears. Conclusions.—Most responding laboratories have implemented the Bethesda 2001 terminology. There is an increase in LBP low-grade squamous intraepithelial lesion rates when compared with 2003 data. Liquid-based preparations have higher median squamous intraepithelial lesion and atypical squamous cell rates.

Background: Cervical cancer is an important public health problem. In Uganda, it ranks the most frequent cause of cancer among women aged between 15 to 44 years of age. Early detection and eradication of cervical cancer and its precursor lesions is the mainstay for control of this disease. The Pap smear method is the most cost-effective means of screening cervical pre-malignant, malignant processes and non-neoplastic lesions. Aim: To describe the cervical cytological abnormalities as detected byPap smear method and to determine the prevalence of such abnormalities Methodology: This was a prospective study, in which a total of 175 women were recruited from May to June, 2016. Cervical samples were collected from these women and stained according to the papanicolaou staining protocol. Results were reported using the 2014 Bethesda reporting system. Results: Out of 175 cases, 163 (93.1%) were reported as negative for intraepithelial lesion or malignancy [NILM]. Cervical intraepithelial lesions were reported in 12 (6.9%) cases which included atypical squamous cells of undetermined significance [ASCUS] in 4(2.3%) cases, atypical squamous cells cannot exclude high grade squamous intraepithelial lesions [ASCH] in 1(0.6%) case, low-grade squamous intraepithelial lesion [LSIL] in 5 (2.9%) cases, high-grade squamous intraepithelial lesion [HSIL] in 1(0.6%) case and atypical glandular cells [AGC] in 1(0.6%) case. Conclusion: Cervical cytology by Pap smear method should be used to screen women routinely because it is an effective method in detecting pre-malignant and malignant lesions of the cervix.

Abstract Objective.—To determine whether, on a national cytology proficiency test, a competent cytologist can consistently distinguish grades of squamous intraepithelial lesions. Design.—Results for low- and high-grade squamous intraepithelial lesion referenced slides from the College of American Pathologists Interlaboratory Comparison Program in Cervicovaginal Cytology for 1996 and 1997 were analyzed including educational, nongraded vs graded validated slides. Results.—The discrepant rate between low- and high- grade lesions ranged from 9.8% to 15% for cytotechnologist, pathologist, laboratory, and all responses. There was a statistically significant difference in performance on graded, validated slides vs educational slides with better performance on validated slides. Conclusion.—This significant interobserver variability in subclassification of squamous lesions should be considered in management guidelines for abnormal Papanicolaou test results and implementation of national cytology proficiency testing.
