Eur J Obstet Gynecol Reprod Biol 2023; 280:78-82. [PMID: 36434824 DOI: 10.1016/j.ejogrb.2022.11.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 11/02/2022] [Accepted: 11/18/2022] [Indexed: 11/22/2022]
Abstract
OBJECTIVE To detect factors related to overtreatment with the "Screen-and-treat" approach (S&T) in women with suspicious cervical precancerous lesions. STUDY DESIGN A retrospective observational study of 524 women with high-grade squamous intraepithelial lesions (HSIL) or more severe (HSIL+) in cytology, treated by the Large Loop Excision of the Transformation Zone (LLETZ): 161 without a previous biopsy (S&T group) and 363 with a previous biopsy (biopsy group) from January 2017 to July 2020. The main outcome was a diagnosis of LLETZ: negative (negative or low-grade squamous intraepithlelial lesion LSIL) or HSIL+. A negative diagnosis was interpreted as "overtreatment." Results were analyzed as a function of the S&T approach (whether previous biopsy or not). Variables were obtained from medical records, and were compared with Chi-square or Fisher's exact test (p, p-value), to estimate the chances of a logistic regression analysis (Odds Ratio, OR, or admitting a Confidence Interval (CI) of 95 %). RESULTS No differences were observed in groups regarding menopausal status, smoking, hormonal contraceptive use, colposcopy findings, LLETZ diagnosis, and recurrence. Comparing biopsy vs S&T groups, the frequency of women over 40 years was 28.4 % vs 39.7 % (p = 0.011), and transformation zone type 3 was 12.2 vs 26.8 % (p < 0.001), respectively. In women managed by S&T, when compared to a LLETZ diagnosis, an HSIL+ result was more frequent in women presenting with TZ 1 (93.1 % TZ1 vs 78.5 % TZ2 vs 73.8 % TZ3, p = 0.008) and in women with abnormal colposcopy (92.9 % abnormal vs 38.1 % negative, p < 0.001). Multiple regression analysis found that women with negative colposcopic findings presented a higher risk for negative LLETZ diagnosis (LSIL/Negative final histology) (18.6; 6.18-56.02). CONCLUSIONS No difference was observed in the LLETZ diagnosis in women who did or did not use the S&T approach: it was adequate for women referred by cytological HSIL along with high-grade colposcopic findings.

CIN extension at colposcopy: relation to treatment and blood parameters. JOURNAL OF OBSTETRICS AND GYNAECOLOGY CANADA 2021; 44:255-260. [PMID: 34718148 DOI: 10.1016/j.jogc.2021.10.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Revised: 10/14/2021] [Accepted: 10/14/2021] [Indexed: 11/22/2022]
Abstract
OBJECTIVE To determine the colposcopic lesion size that predicts the presence of residual lesion in patients with cervical intraepithelial neoplasia (CIN) 2/3, to aid gynaecologists in selecting conservative management. METHODS Data from 51 patients with low- and high-grade squamous intraepithelial lesions were evaluated. Colposcopic images were captured and lesion areas were calculated. Polymerase chain reaction (PCR) for human papillomavirus was performed. Laboratory parameters were evaluated. Receiver operating characteristic (ROC) curves were used to obtain cut-off values for lesion area. The performance of PCR in the detection of high-grade CIN was assessed. A flowchart was created to compare the costs of related procedures in the Brazilian health system. RESULTS For CIN 2/3 treated with excisional surgery, the best cut-off value for lesion area below which no residual lesion was present was 21 019 pixels2 (58.87 mm2). The cut-off value that predicted compromised surgical margins was 155 577.65 pixels2 (435.75 mm2). Among all patients with CIN, lesion area correlated inversely with neutrophil/lymphocyte ratio (NLR; r = -0.446, P = 0.001), platelet/lymphocyte ratio (PLR; r = -0.438, P = 0.001), and absolute number of leukocytes (r = -0.351, P = 0.011). Conservative clinical management with semi-annual clinical follow-up was found to reduce direct costs to the Brazilian Health System by R $909.82 (US $169.42). CONCLUSION CIN reflects systemic alteration, leading to altered NLRs, PLRs, and absolute numbers of leukocytes. Patients with high-grade CIN and colposcopic lesion areas <21 019 pixels2 could benefit from conservative management, which would result in cost savings for the Brazilian health system.

Abstract
Cervical cancer is a major worldwide health problem. Therefore, regular cervical screening in order to make an early diagnosis can help to prevent cervical cancer, through identifying and treating preinvasive cervical lesions. The aim of this review is to evaluate the correlation between the cytological screening result and the final gold standard histological outcome in the diagnosis of cervical lesions. More specifically, the correlation between high-grade intraepithelial lesion (HSIL) on cytology and histological cervical intraepithelial neoplasia grade 2 or higher (CIN2+) was intended, by calculating the positive predictive value (PPV). PPV is an important value from a clinical point of view. An electronic search was carried out in the electronic databases MEDLINE (through PubMed) and the Cochrane Library (last searched beginning of December 2017), supplemented with the related article feature in PubMed and snowballing. Article selection (predefined inclusion and exclusion criteria) and data extraction were evaluated by two independent reviewers (N.K. and A.V.L.). After identifying 1,146 articles, 27 articles were finally included in this systematic review, representing 28,783 cytological HSIL diagnoses in total. The PPV of HSIL was 77.5% (range: 45.4-95.2%) for the histological diagnosis of CIN2+ and 55.4% (range: 36.4-67.6%) for the diagnosis of CIN3+. In this systematic review, 77.5% of the HSIL-positive women eventually had a CIN2+ diagnosis. The diagnostic value of a cytological HSIL result (conventional or liquid-based cytology) in the diagnosis of CIN2+ lesions is good, but a combination of tests could raise this value.

Colposcopy Evaluation at the Time of Loop Electrosurgical Excision Procedure May Avoid Unnecessary Treatment. J Low Genit Tract Dis 2018; 22:367-374.

Abstract
OBJECTIVE The aim of the study was to assess the accuracy of colposcopy evaluation at the time of the loop electrosurgical excision procedure (LEEP) to identify women with a previous confirmatory diagnosis of squamous intraepithelial lesion/cervical intraepithelial neoplasia (SIL/CIN) with low probability of dysplasia in the LEEP specimen. MATERIALS AND METHODS We prospectively recruited a cohort of 162 women undergoing LEEP for histological high-grade SIL/CIN 2-3 or low-grade SIL/CIN 1 with high-grade SIL cytology showing a fully visible squamocolumnar junction in the colposcopy evaluation at the time of LEEP. At the referral visit cervical cytology, human papillomavirus and genotype detection, digital colposcopy, colposcopical lesion measurement, and 1 or more biopsies of the transformation zone were obtained. The uterine cervix was colposcopically evaluated intraoperatively. RESULTS Thirty-four women (21.0%) had a normal colposcopy evaluation at the time of the LEEP, whereas the remaining 128 women showed abnormal findings. Absence of SIL/CIN in the LEEP specimen was confirmed in 28 (82.3%) of the 34 women with a normal colposcopy at the time of LEEP group and 8 (3.1%) of the 128 women showing abnormal colposcopy at the time of LEEP group (p < .001). A normal colposcopic evaluation at the time of LEEP was associated with an increase in the risk of absence of lesion in the cone specimen compared with cases presenting an abnormal colposcopy (95% CI = 33.8-1,555.1, p < .001). The colposcopy evaluation at the time of LEEP had a positive predictive value of 82.3% (95% CI = 66.5-91.5) and a negative predictive value of 96.9% (95% CI = 92.2-98.8) to predict low probability of SIL/CIN in the specimen. CONCLUSIONS Colposcopic evaluation at the time of LEEP seems to be accurate to identify SIL/CIN postbiopsy regression; thus, its performance would be considered at the time of the treatment.

Abstract
OBJECTIVE To evaluate whether colposcopic measurement of the lesion size at diagnosis and/or human papillomavirus (HPV) genotyping can predict the absence of dysplasia in a large loop excision of the transformation zone (LLETZ) specimen in women treated for squamous intraepithelial lesions/cervical intraepithelial neoplasia (SIL/CIN). DESIGN Prospective observational study. SETTING Tertiary university hospital. POPULATION A cohort of 116 women who underwent LLETZ because of biopsy-proven low-grade SIL/CIN that had persisted for 2 years, or because of a high-grade SIL/CIN diagnosed in the referral visit and squamocolumnar junction completely visible (types 1 or 2, according to the International Federation of Cervical Pathology and Colposcopy, IFCPC). METHODS After LLETZ the women were classified by histology into the study group (absence of SIL/CIN in the surgical specimen, 28/116, 24.1%) and the control group (SIL/CIN in the LLETZ specimen, 88/116, 75.9%). MAIN OUTCOME MEASURES The size of the lesion determined in the diagnostic colposcopy and the HPV genotype were evaluated in all women. RESULTS The lesion size was significantly smaller in the study group (25.7 ± 37.8 versus 84.5 ± 81.7 mm2 ; P < 0.001). A lesion size of ≤12 mm2 and HPV types other than 16 or 18 were associated with an absence of SIL/CIN in the LLETZ specimen (P < 0.001 and P = 0.016, respectively). On multivariate analysis only a lesion size of ≤12 mm2 predicted the absence of SIL/CIN (odds ratio, OR 10.6; 95% confidence interval, 95% CI 3.6-30.6; P < 0.001). A lesion size of ≤12 mm2 had a specificity of 90.9% (95% CI 83.0-95.3%) and a negative predictive value of 86.0% (95% CI 77.5-91.6%) to predict the absence of SIL/CIN in the surgical specimen. CONCLUSIONS Small lesion size in diagnostic colposcopy could predict the absence of SIL/CIN in the LLETZ specimen. Colposcopy measurement of lesion size prior to LLETZ may avoid unnecessary treatment. TWEETABLE ABSTRACT Small lesion size in colposcopic evaluation might predict the absence of SIL/CIN in an LLETZ specimen.

Abstract
Cervical cytology remains the principal screening method to detect pre-invasive and invasive cervical lesions. Management of abnormal cervical cytology depends on the risk of encountering a significant cervical lesion or high-grade cervical disease. These risks may vary in different areas across the country. Thus, determining the rate of significant cervical lesion associated with each type of abnormal cervical cytology in each area is of critical importance for designing area-specific management approach. This review was conducted to evaluate the rate of high-grade cervical disease among Thai women with abnormal cervical cytology. A relatively high incidence of underlying significant lesions including invasive disease was demonstrated even in those having only minimal smear abnormality. This baseline information is crucial and must be taken into consideration in management of women with abnormal cytological screening to achieve the goals of comprehensive cervical cancer control in Thailand.

Abstract
AIM Cervical large loop excision of the transformation zone (LLETZ) specimens are performed both to treat and to diagnose or exclude cervical pre-neoplasia. Examination of these specimens forms a significant part of the routine histological work load of the pathologist, yet histological confirmation of squamous intraepithelial lesion (SIL) or completeness of excision, does not alter the treatment of SIL. When the LLETZ procedure is done, the treatment is complete, the dysplasia having been subject to excision as well as diathermy during the procedure. METHOD In this study, records of 1139 women who underwent LLETZ treatment for SIL were examined. The grade of SIL present and the margin status were extracted from histology reports and linked to post-LLETZ follow-up cytology and histology, for a period of 2 years. RESULTS SIL recurrence in women with high grade (HG-SIL), low grade SIL (LG-SIL) and normal LLETZ biopsy results was not significantly different. There was no significant difference between the recurrence rates of HG-SIL and LG-SIL with SIL at margins compared to SIL clear of margins. DISCUSSION Pathologists spend significant time examining multiple levels of LLETZ biopsies, grading SIL, determining margins and trying to find SIL in 'normal' LLETZ biopsies. None of this affects the subsequent follow-up. The most useful data the pathologist can provide is whether invasion is present or not. Pathological effort should be directed to examining multiple levels of those with HG-SIL to find invasion, rather than spending time looking at multiple levels of normal or LG-SIL LLETZ biopsies.

Abstract
OBJECTIVE Absence of dysplasia in the excised specimen following loop electrosurgical excision procedure (LEEP) for treatment of cervical intraepithelial neoplasia (CIN) 2/3 is an occasional finding of uncertain clinical significance. We evaluated several factors including age, liquid-based Pap (LBP) test, human papillomavirus (HPV) load before treatment, and HPV typing as predictors for absence of dysplasia. Absence of dysplasia in LEEP specimens was analyzed in terms of factors for recurrent disease after LEEP conization METHODS In total, 192 women (mean age, 39.3+/-8.4 years; range, 24 to 70 years) with biopsy-proven CIN 2/3 were treated by LEEP conization. Age, LBP test, histological grade, HPV load, and HPV DNA typing were evaluated as possible predictors of the absence of residual dysplasia or recurrent disease. RESULTS Of the LEEP specimens, 34 (17.7%) showed no dysplasia in preoperative biopsies from patients with proven CIN 2/3. Low HPV load (<100 relative light units [RLU]) was significantly related to the absence of dysplasia in LEEP specimens, using logistic regression. Margin involvement and high HPV load (>/=400 RLU) were significant factors for recurrence. CONCLUSION Absence of dysplasia in LEEP specimens occurred in 17.7% of our specimens. Prediction of the absence of dysplasia in LEEP specimens was associated with low HPV load. Residual/recurrent disease after LEEP was associated with a positive resection margin and high viral load, and was not associated with absence of dysplasia in LEEP specimens. Even if there is no dysplasia in conization specimens, close follow-up for residual/recurrent disease is needed.

Abstract
The aim of this study was to determine the extension of cervical intraepithelial neoplasia grade III (CIN III) into endocervical canal and depth of endocervical crypts involvement by CIN with the regard to patients' age and parity. Correlation between the area of CIN involvement and the extension into endocervical canal was estimated. A total of 218 cervical cone specimens with histologically proven CIN III were included in this study. Extension of CIN into the endocervical canal, depth of involved crypts and ectocervical area affected by CIN were histologically analyzed. The average endocervical crypt involvement was at 1.2 mm of depth. The excision of >4 mm (1.2 mm x 3S.D.) in depth removes >99% of CIN. With the cone length of 15 mm (nulliparous patients) and 18 mm (multiparous patients), no endocervical cone margins were affected with CIN. Since the cone length is the most important determining factor for fertility preservation, the measurement of cervical cone could be essential for future pregnancies.

Abstract
OBJECTIVE The study's subject was to examine the correlation between histologic findings in patients with high-grade squamous intraepithelial lesion (HGSIL) who have undergone loop electrosurgical excisional procedure (LEEP) with and without prior colposcopically directed biopsy. STUDY DESIGN This retrospective study included 144 patients with cytologic HGSIL, of which 62 were treated by a three-step protocol, in which LEEP was performed only if the colposcopically directed cervical biopsies were positive (CIN II-III), and 82 women who were treated by "see and treat" protocol, in which LEEP was immediately performed if colposcopy was suggestive of CIN II or III lesions. RESULTS There were no differences in the final histological findings between the groups. CONCLUSIONS The colposcopically directed LEEP after a HGSIL on PAP-smear may reduce the time interval between diagnosis and treatment with a similar accuracy of diagnosis compared to the standard three-step protocol.

Abstract
Management of cervical preneoplasia starts with an abnormal smear result. The use of the Bethesda system is recommended. The management of patients with low-grade abnormal smear results varies around the world. Patients with atypical squamous cells on cytology are recommended to be subclassified into atypical squamous cells of undetermined significance (ASCUS) and atypical squamous cells where high-grade squamous intra-epithelial lesions (HSIL) cannot be excluded (ASCH) groups. While patients with ASCUS can be followed with cytology or colposcopy, the risk of having cervical intra-epithelial neoplasia (CIN) is higher in patients with ASCH. Such patients, as well as those with low-grade squamous intra-epithelial lesions on cytology, should be referred for colposcopy to ensure that diagnosis and treatment in CIN is detected. Patients with HSIL should be referred promptly for colposcopic assessment. This should, usually at the same clinic visit, be followed by large loop excision of the transformation zone (LLETZ). Although this is effective treatment, around 15% of patients will have persistent/recurrent disease on cytological follow-up. Patients with positive human papillomavirus DNA tests at follow-up seem to have a considerably higher risk of recurrent preneoplasia than those who have negative tests. Patients over 50 years of age have much higher recurrence risks than younger patients. These factors impact on second-line treatment and follow-up schedules. An important benefit of conservative treatment for CIN with LLETZ is retention of fertility. LLETZ is associated with an increased risk of preterm prelabour rupture of membranes and preterm birth, but not with other adverse pregnancy outcome measures. Conservative excisional management of adenocarcinoma in situ by LLETZ or cold knife cone biopsy is not reported to be as effective as that of CIN, with high risk of residual and recurrent disease at follow-up. Conversely, LLETZ may be acceptable treatment for micro-invasive squamous carcinoma if the excision margins are free of disease and there is no evidence of lymphovascular involvement. The ability to detect and treat premalignant lesions on the cervix reversed the natural history of cervical cancer. Methods of conservative treatment that evolved over decades have been proven safe and effective, allowing retention of fertility. Good clinical guidelines have been developed for most clinical scenarios while some uncertainties persist for other scenarios.
