Intraepithelial Lesions

Objective A vulvar squamous intraepithelial lesion is deemed to be a preceding lesion to vulvar cancer, especially in women aged under 40 years, holders of an acquired or idiopathic immunosuppression. Several treatments have been used to treat these lesions. One of the aesthetically acceptable therapeutic methods is the CO2 laser vaporization. Methods In a transversal study, 46 records of immunosuppressed women bearing a vulvar low grade and/or high grade squamous intraepithelial lesion were selected out of the retrospective analysis, computing age, date of record, date of vulvar lesion treatment with CO2 laser, the time elapsed between the first and the last visit (in months), the number of visits, the presence or absence of condylomatous lesions in other female lower genital tract sites and whether or not recurrences and persistence of intraepithelial lesions have been noticed during the follow-up. Results Patients bearing vulvar high-grade squamous intraepithelial lesion and immunosuppressed (serum positive for human immunodeficiency virus [HIV] or with solid organs transplantation) have shown a higher level of persistence of lesions and a higher chance of having other areas of the female lower genital tract involved. Conclusion While the CO2 laser vaporization is the most conservative method for the treatment of vulvar high-grade intraepithelial lesions, it is far from being the ideal method, due to the intrinsic infection features considered. The possibility of persistence, recurrences and spontaneous limited regression indicates that a closer surveillance in the long-term treated cases should be considered, in special for immunosuppressed patients.

Abstract Context.—Both conventional and ThinPrep Papanicolaou smears with high-grade squamous intraepithelial lesions that are frequently missed are known to have relatively few abnormal cells. Whether this is also true of cases of low-grade squamous intraepithelial lesion is not known. Objective.—To compare the cytologic features of cases of low-grade squamous intraepithelial lesion that perform poorly with the features of cases that perform well. Design.—The cytologic features of 10 ThinPrep Pap Test and conventional smear cases of low-grade squamous intraepithelial lesion that performed poorly in the College of American Pathologists Interlaboratory Comparison Program were compared with 46 ThinPrep Pap Test and conventional smear cases that performed extremely well. The numbers of abnormal cells were categorized into less than 50, 51 to 100, 101 to 250, 251 to 500, and more than 500. Results.—The median number of abnormal cells for cases that performed poorly was less than 50, whereas the median number of abnormal cells for cases that performed well was between 101 and 250. Overall, cases that performed poorly were significantly more likely to have less than 50, less than 100, and less than 250 abnormal cells than cases that performed well (P < .001, P < .001, and P = .009, respectively). A minority of cases performed well even with very few abnormal cells and groups. The same findings were present when conventional smears and ThinPrep specimens were analyzed separately. Conclusions.—ThinPrep Pap Test cases and conventional smears with a diagnosis of low-grade squamous intraepithelial lesion that perform poorly in this program have significantly fewer abnormal cells than those that perform well. The median number of abnormal cells in cases that performed well is lower than that of comparable high-grade cases in the program.

Background: ‘AgNOR’ represents Nucleolar Organiser Regions stained with silver which are related to cell proliferation rate and tumor malignant potential. The objective of this study was to evaluate the role of AgNOR in differentiating benign and precancerous lesions from cancerous lesions in both cervical smears and histology. Materials and Methods: This was a prospective study conducted at Manipal Teaching Hospital, from July 2005 to June 2007. Women of suspected cervical pathology and who underwent pap smears test followed by subsequent biopsy were included. There were 53 cases were included out of which 11 cases were of high grade squamous intraepithelial lesion and 12 cases of low grade squamous intraepithelial lesion, and 10 cases each of carcinoma, chronic cervicitis with and without squamous metaplasia. Results: In Low grade squamous intraepithelial lesion meanAgNOR dots was < (2.9 in pap smears and 1.9 in histology) in high grade lesion (3.45 in pap smears and 3.00 in histology). In carcinoma meanAgNOR dots was 5.18 and 4.05 in pap smears and histology respectively. Subjective AgNOR Pattern Assessment in pap smears and in histology was increasing with significant difference from intraepithelial lesions to carcinoma. Conclusion: In cervical pathology, the number and shape of AgNOR dots change from benign to precancerous to malignant tumors. Similarly, AgNOR Pattern Assessment is useful in differentiating benign to intraepithelial lesions to carcinoma cases. DOI: http://dx.doi.org/10.3126/jpn.v2i3.6017 JPN 2012; 2(3): 180-185

HPV infection is known to cause cervical cancer. This study aimed to identify the variant of HPV genotypes of cervical precancerous lesions from low grade squamous intraepithelial lesion  (LSIL) and high grade squamous intraepithelial lesion (HSIL). This was an explorative study using formalin fix paraffin embedded (FFPE) from cervical precancerous lesions at Dr. Soetomo Hospital, Surabaya. DNA was extracted from FFPE and hybridized for HPV genotyping using Ampliquality HPV Type Express kit (AB ANALITICA) by reverse line blot techniques. The results showed that there were variants of HPV genotype in LSIL. The variants were HPV16 (8/15), HPV18 (3/15), HPV52 (1/15), HPV6+31 (1/15), HPV6+18 (1/15), and HPV72+68 (1/15), and in HSIL which were HPV16 (4/10), HPV18 (2/10), HPV59 (1/10), HPV6+45 (1/10), HPV61+26 (1/10), and HPV16+31 (1/10). The characteristics of infection in LSIL were single infection of high-risk (hr) HPV and multiple infection of  low-risk (lr)+hr HPV, and in HSIL were single infection of HPVhr, multiple infection of HPVhr+hr and HPVlr+hr. In conclusion, HPV prevalence in cervical precancerous lesions is single infection by HPV16 (48%), HPV18 (20%), HPV52 (4%), HPV59 (4%), and multiple infection by HPV6+31, HPV6+18, HPV6+45, HPV16+31, HPV61+26, HPV72+68 is 4%.

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.

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.

Cytology Screening

Background: Clinicians commonly perform colposcopy directed biopsies on patients with low grade squamous intraepithelial lesion (LSIL) on PAP cytology even when not consistent with clinical guidelines. Objective: We study the association of PAP cytology screening results with cervical intra-epithelia neoplasia (CIN) 2-3 high-grade dysplasia, as confirmed by colposcopy-directed biopsy. Methods: A retrospective study of 263 women with an abnormality on the PAP smear. Multinomial logistic regression was performed with predictors of PAP cytology screening results with the outcome variable of colposcopy-directed biopsy. Results: High grade squamous intraepithelial lesion (HSIL) had significantly increased relative risk for CIN 2-3 (RR: 9.85, 95% CI: 1.84, 52.79, p=0.008). LSIL was not significantly associated with CIN 2-3. In the comparisons of negative with CIN-1, both HSIL and LSIL were not significantly associated with a negative biopsy. Conclusion: HSIL is associated with cervical dysplasia of CIN 2-3 while LSIL is not associated with cervical dysplasia of CIN 2-3. We do not recommend routine biopsies in patients with LSIL cytologic abnormalities unless additional compelling factors exist.

Diagnostic Concordance

Context.— Obtaining diagnostic concordance for squamous intraepithelial lesions in cytology can be challenging. Objective.— To determine diagnostic concordance for biopsy-proven low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion (HSIL) Papanicolaou test slides in the College of American Pathologists PAP Education program. Design.— We analyzed 121 059 responses from 4251 LSIL and HSIL slides for the interval 2004 to 2013 using a nonlinear mixed-model fit for reference diagnosis, preparation type, and participant type. We evaluated interactions between the reference diagnosis and the other 2 factors in addition to a repeated-measures component to adjust for slide-specific performance. Results.— There was a statistically significant difference between misclassification of LSIL (2.4%; 1384 of 57 664) and HSIL (4.4%; 2762 of 63 395). There was no performance difference between pathologists and cytotechnologists for LSIL, but cytotechnologists had a significantly higher HSIL misclassification rate than pathologists (5.5%; 1437 of 27 534 versus 4.0%; 1032 of 25 630; P = .01), and both were more likely to misrepresent HSIL as LSIL (P &lt; .001) than the reverse. ThinPrep LSIL slides were more likely to be misclassified as HSIL (2.4%; 920 of 38 582) than SurePath LSIL slides (1.5%; 198 of 13 196), but conventional slides were the most likely to be misclassified in both categories (4.5%; 266 of 5886 for LSIL, and 6.5%; 573 of 8825 for HSIL). Conclusions.— More participants undercalled HSIL as LSIL (false-negative) than overcalled LSIL as HSIL (false-positive) in the PAP Education program, with conventional slides more likely to be misclassified than ThinPrep or SurePath slides. Pathologists and cytotechnologists classify LSIL equally well, but cytotechnologists are significantly more likely to undercall HSIL as LSIL than are pathologists.

Adenoid basal carcinoma of the uterine cervix is a rare low-grade tumor and its cell origin is still obscure. Adenoid basal carcinoma can be confused with adenoid basal hyperplasia, adenoid cystic carcinoma, and basaloid squamous cell carcinoma of the cervix. We present here a case of a 59 year-old-female who initially presented with a high-grade squamous intraepithelial lesion on Pap smear. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. Histopathology revealed focal invasive adenoid basal carcinoma with extensive areas of a high-grade squamous intraepithelial lesion involving the endocervical gland. The immunohistochemical stain was positive for p16.

AbstractIntroductionHigh-risk human papilloma virus (HPV)-associated cervical cancer is the fourth most common cancer in women worldwide. Current treatments of high grade squamous intraepithelial lesion (HSIL) of the cervix are based on invasive surgical interventions, compromising cervical competence and functionality.ObjectiveAPRICITY is a multicentre, prospective, double-blind, randomised controlled Phase 3 study further evaluating the efficacy and safety of Cevira®, an integrated drug- and light-delivery device for hexaminolevulinate photodynamic therapy, which shows promise as a novel, non-invasive therapy for women with HSIL.Methods and analysisPatients with biopsy-confirmed HSIL histology are invited to participate in the study currently being conducted at 47 sites in China and 25 sites in Ukraine, Russia and European Union. The aim is to include at least 384 patients which will be randomised to either Cevira® or placebo group (2:1). All patients will be assessed 3 months after first treatment and a second treatment will be administered in patients who are HPV positive or have at least low grade squamous intraepithelial lesion (LSIL). Primary endpoint is the proportion of the responders at 6 months after first treatment. Secondary efficacy endpoints and safety endpoints will be assessed at 6 months, and data for secondary performance endpoints for Cevira® device will be collected at 3 months and 6 months, in case second treatment was administered. All patients in the Cevira® group will be enrolled in an open, long-term extension study following patients for further 6 months to collect additional efficacy and safety data (study extension endpoints).ConclusionDue to its non-invasiveness and convenient application, Cevira® may be a favourable alternative to surgical methods in treatment of patients with HSIL.Ethics and disseminationThe study was approved by the ethics committee of the Peking Union Medical College Hospital and Hannover Medical University, Germany. Findings will be disseminated through peer review publications and conference presentations.Trial registration numberclinicaltrials.govNCT04484415

<p>This study evaluates the statistical analysis of cervicovaginal smear results at postmenopausal period accompanied by literature. Cervicovaginal smear results of 894 postmenopausal women were evaluated retrospectively according to the 2001 Bethesda system (BS) in Adana Numune Training and Research Hospital of Obstetrics and Gynecology Clinic from 2007–2010. The study found, normal results on 287 patients (32.1%), benign findings on 556 patients (62.2%), abnormal epithelial cell changes on 48 patients (5.36%) and malignant changes on 3 patients (0.33%). The abnormal epithelial changes were observed to be atypical cells of undetermined significance (ASC-US) for 22 patients (2.46%), <a href="http://medical-dictionary.thefreedictionary.com/high-grade+squamous+intraepithelial+lesion">low-grade squamous intraepithelial lesion</a> (LSIL) for 11 patients (1.23%), <a href="http://medical-dictionary.thefreedictionary.com/high-grade+squamous+intraepithelial+lesion">high-grade squamous intraepithelial lesion</a> (HSIL) for 7 patients (0.78%), findings that cannot exclude a high-grade squamous intraepithelial lesion (ASC-H) for 6 patients (0.55%) and atypical glandular cells-not otherwise specified (AGC-NOS) for 2 patients (0.22%). Malignant results were 2 squamous cell carcinomas (SCC) (0.22%) and 1 adenocarcinoma (ACC) (0.11%). Cervical cancer screening programs should be expanded and Pap smear screening should be applied to all postmenopausal women. The longer time span involved from premalignant lesions to cancer improves our chance for the diagnosis and treatment. As the incidence of invasive cancer increases in menopausal period, gynecological smear examination and regular check-up are crucial. A high rate of abnormalities of epithelial cells was detected in this study.</p><p> </p>
