RESUMO
Objective: To investigate the effects of cervical cold knife conization (CKC) on preterm delivery, other pregnancy complications and neonatal outcomes, and explore the relationship between preterm delivery risk and the depth and volume of conization. Methods: The clinical data and pregnancy outcomes of 272 women who underwent CKC in Peking Union Medical College Hospital from January 2002 to March 2018 (conization group) and 1 647 pregnant women who gave birth in Peking Union Medical College Hospital during January to December 2019 (control group) were collected. The preterm delivery, premature rupture of membranes, other pregnancy complications and neonatal outcomes of the two groups were compared, and the relationship between the depth and volume of conization and the risk of preterm delivery in postoperative singleton pregnancy was analyzed. Results: (1) There were no significant differences between the two groups in delivery age, parity, proportion of singleton pregnancy, proportion of assisted reproductive technology (all P>0.05). (2) The rate of preterm delivery in the conization group was significantly higher than that in the control group [14.8% (39/264) vs 5.7% (91/1 589); χ2=28.397, P<0.001]. There were still significant differences in preterm delivery rates between the two groups at <34 weeks and 34-37 weeks (all P<0.01). There was no significant difference in the incidence of premature rupture of membrane between the two groups [23.5% (62/264) vs 23.4% (372/1 589); χ2=0.001, P=0.979], but the incidence of preterm premature rupture of membrane in the conization group was significantly higher than that in the control group [11.4% (30/264) vs 2.2% (35/1 589); χ2=56.132, P<0.001]. (3) The rate of cesarean section in the conization group was higher than that in the control group [59.6% (162/272) vs 38.8% (639/1 647); χ2=41.377, P<0.001]. The birth weight of preterm infants in the conization group was significantly higher than that in the control group [(2 409±680) vs (2 150±684) g; t=2.184, P=0.030]. However, there were no statistically significant differences in the incidence of gestational diabetes mellitus, hypertensive disorders in pregnancy, the birth weight of full-term infants, incidence of small for gestational age infant and neonatal intensive care unit admission rate between the two groups (all P>0.05). (4) The preterm delivery rates of coning depth >15 mm, cone size ≥2 cm3 and cone size <2 cm3 were higher than that in the control group (all P<0.05). When the coning depth ≤15 mm, the preterm delivery rate in the conization group was higher than that in the control group, but there was no significant difference (P=0.620). The rate of preterm delivery of pregnant women with coning depth >15 mm was significantly higher than those with coning depth ≤15 mm (RR=3.084, 95%CI: 1.474-6.453; P=0.001). There was no significant difference in the preterm delivery rate between pregnant women with cone size >2 cm3 and those with cone size ≥2 cm3 (RR=1.700, 95%CI: 0.935-3.092; P=0.077). Conclusion: The risk of preterm delivery and preterm premature rupture of membranes in subsequent pregnancies are increased after cervical CKC, and the risk of preterm delivery is positively correlated with the depth of cervical coning.

BACKGROUND: Cervical cancer continues to disproportionately burden women in low/middle-income countries like Ghana. We examined treatment patterns and histopathological outcomes among women screened using visual inspection with acetic acid (VIA) and/or mobile colposcopy who subsequently underwent thermal ablation, large loop excision of the transformation zone (LLETZ), or cold knife conization at the Cervical Cancer Prevention and Training Centre, Battor. We also assessed the prevalence of cervical intraepithelial neoplasia 2+ (CIN2+) or micro-invasive disease and their associated factors for women who underwent excisional treatments. The treatment choices for cervical precancerous lesions suitable for resource-limited settings have also been described from the perspective of a center that manages a heterogenous population. METHODS: We conducted an analysis of secondary data collected between June 2016 and June 2023 among women with positive findings on VIA or mobile colposcopy who subsequently underwent thermal ablation or large loop excision of the transformation zone (LLETZ). The prevalence of histopathology outcomes, including no dysplasia, CIN1 - 3, and micro-invasive disease, were estimated with 95% confidence intervals (CIs). Factors associated with histopathological findings were modeled using multinomial logistic regression. RESULTS: For the study period, 14 (10.6%) of the total 132 participants underwent cervical lesion treatment at outreach locations, all via thermal ablation. The remaining 118 (89.4%) were treated at the Catholic Hospital, Battor using LLETZ (n = 66, 55.9%), thermal ablation (n = 51, 43.2%), and cold knife conization (n = 1, 0.9%). Among 65 women with histopathology reports, the most frequent histopathological finding was no dysplasia (47.7%; 95% CI, 35.1 - 60.5), followed by CIN2 and CIN3 (20.0%; 95% CI, 11.1 - 31.8 each), CIN1 (7.7%; 95% CI, 2.5 - 17.0) and micro-invasion (4.6%; 95% CI, 1.0 - 12.9). Those with micro-invasive disease were significantly older than those with CIN1, CIN2, and CIN3 (p = 0.036, 0.022, 0.009, respectively), but not significantly older than those who showed no dysplasia (p = 0.088). For each unit increase in age, the likelihood of CIN3 was relatively significantly reduced compared to no dysplasia (crude relative risk ratio [RRR] = 0.93; 95% CI, 0.86 - 0.99). This association was neither observed with the remaining histopathological groups nor for parity and persisted after controlling for parity (adjusted RRR = 0.92; 95% CI, 0.85 - 0.99; p = 0.025). CONCLUSION: This paper largely demonstrates treatment options available to women and practitioners in LMICs. The high combined prevalence of high-grade precancerous lesions and micro-invasive disease underscores the need to increase cervical cancer awareness that would enhance screening attendance and hasten efforts at moving from opportunistic to organized screening in Ghana. This will enhance early cervical lesion detection and treatment, while simultaneously re-evaluating and cutting down on unnecessary treatment.

INTRODUCTION: Active surveillance for cervical intraepithelial neoplasia grade 2 (CIN2) has been implemented recently in many countries, including the Nordic countries. In Denmark, the only eligibility criterion for active surveillance for CIN2 is that the woman should be of reproductive age. With this study, we aimed to evaluate clinical and socioeconomic characteristics in women with CIN2 managed by active surveillance or large loop excision of the transformation zone (LLETZ) and to evaluate temporal changes in the clinical management of CIN2. MATERIAL AND METHODS: We conducted a Danish nationwide study using data from healthcare registries. All female residents aged 18-40 years, diagnosed with incident CIN2 from January 1, 1998, to February 29, 2020, were included. We collected data on age, index cytology result, year of CIN2 diagnosis, region of residence, civil status, HPV vaccination status, and socioeconomic position indicators. The variables were tabulated overall and by management group (active surveillance vs. LLETZ). To evaluate time trends, we used joinpoint regression to calculate the annual percentage change (APC), including 95% confidence intervals (CI). RESULTS: Of the 27 536 women with CIN2 included, 12 500 (45.4%) underwent active surveillance, and 15 036 (54.6%) underwent a LLETZ. Women undergoing active surveillance were younger, more often HPV-vaccinated, and more likely to have a normal/low-grade index cytology result than women undergoing LLETZ. Socioeconomic position indicators did not differ. Over time, the proportion of women undergoing active surveillance increased from 21.7% in 2004 to 73.6% in 2019 (APC 9.7, 95% CI 8.1-11.4). The proportion of women undergoing active surveillance aged <30 declined over time (APC -2.2, 95% CI -2.9 to -1.5). The proportion of women with normal/low-grade index cytology increased slightly to 51.6% in 2019 (APC 0.8, 95% CI 0.4-1.3). CONCLUSIONS: The use of active surveillance for CIN2 has increased over the past two decades in Denmark. Observed differences in characteristics between women undergoing active surveillance vs LLETZ are likely related to indications for clinical management.

Background and Objectives: Cervical cancer (CC) represents a significant health concern worldwide, particularly for younger women. Cold knife (CK) conization and carbon dioxide (CO2) laser conization are two techniques commonly used to remove pre-invasive lesions, offering a potential curative intent in cases of incidental diagnosis of CC. This study aimed to assess the clinical implications and pathological outcomes of CK vs. CO2 laser conization for pre-invasive lesions. Materials and Methods: We retrospectively analyzed women who underwent CO2 or CK conization for high-grade preinvasive lesions (CIN2/3, CIS and AIS) between 2010 and 2022. Patient demographics, surgical details and pathological outcomes were collected. Pregnancy outcomes, including composite adverse obstetric rates, and oncological follow-up data, were also obtained. Results: In all, 1270 women were included; of them, 1225 (96.5%) underwent CO2, and 45 (3.5%) underwent CK conization. Overall, the rate of positive endocervical or deep margins was lower with CO2 laser compared to CK (4.3% vs. 13.3%, p = 0.015). Incidental CC was diagnosed in 56 (4.4%) patients, with 35 (62.5%) squamous and 21 (46.6%) adenocarcinomas. In a multivariate regression model, the relative risk for positive endocervical or deep margins is significantly greater in cases of incidental diagnosis of CC (p < 0.01). In cases of incidental diagnosis of CC, we found that the probabilities of having either positive endocervical or deep margins after CO2 laser or CK conization are similar, with a higher risk in case of adenocarcinoma lesion. Among women with CC, 42 (75%) opted for radical treatment, while 14 (25%) underwent a follow-up. Only one woman (7.1%) in the follow-up group, who had undergone CK conization, experienced a composite adverse obstetric outcome. No recurrences were observed after a median follow-up of 53 months. Conclusions: CO2 laser conization achieved a lower positive margin rate overall. CK and CO2 conization appear to be equivalent oncological options for incidental CC.

OBJECTIVE: This study aimed to evaluate whether severity changes with colposcopic lesion size, regardless of age. METHODS: This retrospective comparative study reviewed the records of 428 women with altered cytopathology reports who were directed by primary health care. Only those women with colposcopic alterations were evaluated (n=411). Histopathological analyses were restricted to patients who underwent excisional treatment (n=345). According to their age, they were grouped into the following: <21, 21-24, 25-35, and >35 years, and also, ≤24 and ≥25 years. The cytopathological, colposcopic, and histopathological findings were grouped according to severity. Lesion size was subjectively assessed from the colposcopic drawing recorded in the chart and according to the number of quadrants of the total cervical surface affected by colposcopic alterations in the transformation zone. Statistical significance was set at p<0.05. RESULTS: The evaluations suggested that the lesion size was directly related to the severity of the cytopathology, colposcopy, and histopathology reports for the age groups ≤24 or ≥25 years. We observed associations between lesion size and severity of the cytopathology (≤24 years, p=0.037) and histopathology (≥25 years, p=0.003) findings. CONCLUSION: The size of the lesion was directly related to the severity of the histopathological lesion in patients aged ≥25 years and cytopathological in patients aged ≤24 years.

AIM: There is currently no protocol for classifying patients with HPV persistence and preoperative stenosis of the cervical canal. This has a significant impact on cytology results, colposcopy results and the possibility of obtaining reliable cervical histology outcomes. Our analysis clearly shows that colposcopy and cytology underestimate the histological results in patients with limited visibility due to the presence of a type 3 transformation zone (TZ). Our analysis revealed a significant discrepancy between the colposcopy and cytology results and the histological outcomes. Insufficient colposcopy led to the underdiagnosis of dysplastic lesions in patients with a type 3 TZ and cervical stenosis. In the case of repeated cytological abnormalities and inadequate colposcopy examination, it is crucial to perform a diagnostic conization to exclude high-grade dysplastic changes and cervical carcinoma. METHODS: We conducted a retrospective analysis of 1,021 conizations performed in tertiary care hospital in Wolfsburg, Germany between 2014 and 2020. Of these surgical procedures, 89 were diagnostic conizations. In our analysis, we defined diagnostic conization as a procedure performed when there is HPV persistence and repeated cytologic abnormalities in combination with a type 3 TZ, and when it is not possible to retrieve a relevant cervical histology sample. RESULTS: In this period, 8.7% of all conizations were diagnostic excisions. We found histological abnormalities in 48 of 89 patients (53.9%). The histological examination of the excised cone revealed high-grade cervical intraepithelial neoplasia (CIN/HSIL) in 9 patients (10.1%) and CIN 2+ (HSIL) in 23 out of the 89 patients (25.8%). Two cases of early-stage cervical carcinoma (FIGO IA1 and FIGO IA2) were confirmed (2.3%). CONCLUSION: Patients with cervical stenosis, high-risk HPV persistence and repeated cytological abnormalities are at high risk of undetected high-grade cervical dysplasia. Histologic confirmation must be ensured in this patient consultation and this can be achieved by performing diagnostic excisions.

OBJECTIVES: This study aims to analyze factors associated with positive surgical margins following cold knife conization (CKC) in patients with cervical high-grade squamous intraepithelial lesion (HSIL) and to develop a machine-learning-based risk prediction model. METHOD: We conducted a retrospective analysis of 3,343 patients who underwent CKC for HSIL at our institution. Logistic regression was employed to examine the relationship between demographic and pathological characteristics and the occurrence of positive surgical margins. Various machine learning methods were then applied to construct and evaluate the performance of the risk prediction model. RESULTS: The overall rate of positive surgical margins was 12.9%. Independent risk factors identified included glandular involvement (OR = 1.716, 95% CI: 1.345-2.189), transformation zone III (OR = 2.838, 95% CI: 2.258-3.568), HPV16/18 infection (OR = 2.863, 95% CI: 2.247-3.648), multiple HR-HPV infections (OR = 1.930, 95% CI: 1.537-2.425), TCT ≥ ASC-H (OR = 3.251, 95% CI: 2.584-4.091), and lesions covering ≥ 3 quadrants (OR = 3.264, 95% CI: 2.593-4.110). Logistic regression demonstrated the best prediction performance, with an accuracy of 74.7%, sensitivity of 76.7%, specificity of 74.4%, and AUC of 0.826. CONCLUSION: Independent risk factors for positive margins after CKC include HPV16/18 infection, multiple HR-HPV infections, glandular involvement, extensive lesion coverage, high TCT grades, and involvement of transformation zone III. The logistic regression model provides a robust and clinically valuable tool for predicting the risk of positive margins, guiding clinical decisions and patient management post-CKC.

The purpose of this study was to thoroughly evaluate the clinical features and surgical options for high-grade squamous intraepithelial lesions (HSIL) in postmenopausal women. A total of 308 patients diagnosed with HSIL through colposcopic cervical biopsy and endocervical curettage were included. Their clinical characteristics, surgical treatments, and postoperative pathology were analyzed. Key findings include: 1. Patients with positive preoperative thinprep cytologic test (TCT) results and postoperative pathology indicating HSIL or squamous cell carcinoma (≥HSIL) were significantly more frequent than those with negative preoperative TCT results (Pâ <â .05). 2. Univariate analysis indicated significant impacts of TCT, human papillomavirus (HPV) type, transformation zone (TZ) location, and surgical technique on postoperative pathology (Pâ <â .05). 3. Logistic regression analysis confirmed significant influences of TCT, HPV type, TZ location, and surgical method on postoperative pathology outcomes (Pâ <â .05), showing that each unit increase in TZ raised the probability of ≥HSIL in postoperative pathology by 49.7%. In surgical comparisons, cold knife conization (CKC) and extrafascial hysterectomy resulted in 8.379 and 4.427 times higher probabilities of ≥HSIL in postoperative pathology, respectively, compared to loop electrosurgical excision procedure (LEEP). 4. Surgical methods significantly influenced margin results (Pâ <â .05). After LEEP, 17.5% of cases had positive margins, compared to 9.4% after CKC, and 3.7% after extrafascial hysterectomy, indicating the highest rate of positive surgical margins occurred with LEEP. 1. Combined TCT and HPV screening is crucial for cervical cancer prevention, early detection, and management in postmenopausal women. Women with positive results for both TCT and HPV should undergo colposcopic cervical biopsy and endocervical curettage. 2. For patients with TZ3, CKC is the recommended surgical option. 3. CKC is the preferred treatment for postmenopausal women with HSIL, as it effectively diagnoses and treats the lesion, showing superior outcomes in managing postmenopausal HSIL.

BACKGROUND: The purpose of this study was to predict the risk factors for residual lesions in patients with high-grade cervical intraepithelial neoplasia who underwent total hysterectomy. METHODS: This retrospective study included 212 patients with histologically confirmed high-grade cervical intraepithelial neoplasia (CIN2-3) who underwent hysterectomy within 6 months after loop electrosurgical excision procedure (LEEP). Clinical data (e.g., age, menopausal status, HPV type, and Liquid-based cytology test(LCT) type), as well as pathological data affiliated with endocervical curettage (ECC), colposcopy, LEEP and hysterectomy, were retrieved from medical records. A logistic regression model was applied to estimate the relationship between the variables and risk of residual lesions after hysterectomy. RESULTS: Overall, 75 (35.4%) patients had residual lesions after hysterectomy. Univariate analyses revealed that positive margin (p = 0.003), glandular involvement (p = 0.017), positive ECC (p < 0.01), HPV16/18 infection (p = 0.032) and vaginal intraepithelial neoplasia (VaIN) I-III (p = 0.014) were factors related to the presence of residual lesions after hysterectomy. Conversely, postmenopausal status, age ≥ 50 years, ≤ 30 days from LEEP to hysterectomy, and LCT type were not risk factors for residual lesions. A positive margin (p = 0.025) and positive ECC (HSIL) (p < 0.001) were identified as independent risk factors for residual lesions in multivariate analysis. CONCLUSIONS: Our study revealed that positive incisal margins and ECC (≥ CIN2) were risk factors for residual lesions, while glandular involvement and VaIN were protective factors. In later clinical work, colposcopic pathology revealed that glandular involvement was associated with a reduced risk of residual uterine lesions. 60% of the patients with residual uterine lesions were menopausal patients, and all patients with carcinoma in situ in this study were menopausal patients. Therefore, total hysterectomy may be a better choice for treating CIN in menopausal patients with positive margins and positive ECC.

BACKGROUND: Early diagnosis and treatment of HPV persistent infection and cervical intraepithelial neoplasia, which have yet to be thoroughly characterized in Guangxi, Southwestern China, are the key preventative measures for the development of cervical cancer in women, particularly in HIV-infected women. METHODS: A retrospective study of 181 patients with HPV infection or cervical intraepithelial neoplasia who received surgical excision of lesions and were prospectively enrolled at the Fourth People's Hospital of Nanning between January 2018 and February 2023 was performed. HPV-infected patients were divided into two subgroups: HIV-infected and HIV/HPV-coinfected patients and compare differences between these groups. RESULTS: HPV16, 18, 52, and 58 were the most prevalent HPV genotypes. High-risk HPV was significantly co-infected with multiple genotypes (P = 0.0332). HIV-infected women were predisposed to HPV infection (P < 0.0001), and the development of cervical cancer at a young age (P = 0.0336) compared to HIV-uninfected women and the loop electrosurgical excision procedure (P = 0.0480) is preferred for the treatment. CONCLUSIONS: HIV infection may increase HPV prevalence and lead to cervical cancer development at a young age. The loop electrosurgical excision procedure is an efficient evaluation and treatment strategy for HIV-infected women suffering from cervical intraepithelial neoplasia.

OBJECTIVE: Investigate the association between p16/Ki-67 dual stain cytology test (DST) results, obtained prior to- and 6 months after LLETZ surgery for treatment of CIN, and the follow-up regimen three years after treatment. METHODS: Secondary analysis of a prospective cohort study. Cervical cytology samples were obtained just prior to- and 6 months after LLETZ and underwent conventional liquid-based cytology (LBC) and p16/Ki-67 dual staining, as well as high-risk HPV genotyping. Clinical management after the LLETZ was according to Belgian national guidelines, with clinicians being blinded to DST results at both time points. Case records were reviewed in 01/2023 to document the follow-up regimen on average three years afterwards: women had either been advised to return to routine screening (i.e., three-annual LBC testing according to the Belgian guideline at that time), or were still subject to more frequent posttreatment surveillance (i.e., more frequent visits because of persistent hrHPV infection or absence of cytological regression). RESULTS: The follow-up regimen was recorded in 79/110 women originally recruited (72%). The need for continued intense posttreatment surveillance was associated with hrHPV infection 6 months after treatment (79.3% vs. 18.0%, p < 0.001), a positive DST result at baseline and follow-up (41.4% vs. 84.0%, p < 0.001-55.2% vs. 16.0%, p < 0.001), and persistent cytological anomalies at 6 months (at an ASCUS or worse threshold, 37.9% vs. 16.0%, p = 0.028). In multivariable logistic regression analysis, a positive DST at baseline (aOR 20.1, 95%CI 2.03-199.1) was independently associated with the need for intense post-treatment surveillance multiple years after treatment. CONCLUSION: This exploratory study suggests a possible role of dual-stain cytology in predicting treatment outcome multiple years after LLETZ surgery.

OBJECTIVE: To identify the risk factors of cervical high-grade squamous intraepithelial lesion(HSIL) complicated with occult cervical cancer and standardize the management of initial treatment for HSIL. METHOD: The clinical data of patients who underwent total hysterectomy directly due to HSIL in the obstetrics and gynecology department of two tertiary hospitals and three secondary hospitals from 2018 to 2023 were collected. Their general characteristics, pathological parameters and survival status were analyzed. Logistic regression model was used to analyze the correlation between clinical parameters and postoperative pathological upgrading. RESULT: 1. Among the 314 patients with HSIL who underwent total hysterectomy directly, 73.2% were from primary hospitals. 2. 25 patients (7.9%) were pathologically upgraded to cervical cancer, all of which were early invasive cancer. 3. Up to now, there was no recurrence or death in the 25 patients with early-stage invasive cancer, and the median follow-up period was 21 months(range 2-59 months). 4. Glandular involvement(OR 3.968; 95%CI 1.244-12.662) and lesion range ≥ 3 quadrants (OR 6.527; 95% CI 1.78-23.931), HPV 16/18 infection (OR 5.382; 95%CI 1.947-14.872), TCT ≥ ASC-H (OR 4.719; 95%CI 1.892-11.766) were independent risk factors that affected the upgrading of postoperative pathology. 5. The area under the curve (AUC) calculated by the Logistic regression model was 0.840, indicating that the predictive value was good. CONCLUSION: There is a risk of occult cervical cancer in patients with HSIL. Glandular involvement, Lesion range ≥ 3 quadrants, HPV 16/18 infection and TCT ≥ ASC-H are independent risk factors for HSIL combined with occult cervical cancer. The prognosis of biopsy-proved HSIL patients who underwent extrafascial hysterectomy and unexpected early invasive cancer was later identified on specimen may be good.

OBJECTIVES: To investigate the relationship between preoperative inflammatory markers and recurrence of CIN after loop electrosurgical excision procedure (LEEP). METHODS: A retrospective historical cohort study was conducted at gynecologic oncology unit, Bhumibol Adulyadej Hospital, Royal Thai Air Force, Thailand. Data was collected from medical records of CIN cases from year 2016 to 2021. Inclusion criteria were subjects who were diagnosed of CIN and underwent LEEP with pathologic confirmation and followed up for two years (at 6 months, 1 year, and 2 years). Preoperative complete blood count (CBC) was obtained within one month for calculation as systemic inflammatory values. RESULTS: One hundred and ten cases of CIN were enrolled. Mean age of participants was 48.1 years old. Three-fourths (83/110) of the participants had histological confirmation as CIN2/3. Sixteen (18/110) and twenty (22/110) percentage of cases had recurrence of disease at 1 and 2 years, respectively. Monocytes /lymphocytes ratio (MLR) and systemic inflammation response index (SIRI) could predict recurrence of CIN within 2 years. MLR more than 0.16 and SIRI more than 0.57 gave the sensitivity and negative predictive value (NPV) at percentage of 77.3/ 81.8 and 91.8/ 90.2, respectively. Combination of MLR and SIRI had sensitivity and NPV at 90.5 and 95.4 percent, respectively. MLR and SIRI could not predict marginal involvement, glandular involvement, and LEEP confirmed CIN 2/3. CONCLUSION: Pretreatment MLR and SIRI were statistically significant in predicting the recurrence in CIN after post LEEP procedure within 2 years follow up.

BACKGROUND: The prevention of cervical cancer can be achieved by treating high-grade cervical precancerous lesions. Treatment options for cervical precancer include excisional procedures, and ablation treatments. Despite the long pre-invasive course of the disease, literature addressing sexual function post-treatment for cervical pre-invasive lesions is scarce. This study aims to bridge this gap and assess the sexual function and the acceptability, efficacy, safety, and complications of loop electrosurgical excision procedure (LEEP) versus thermal ablation. METHODS: The prospective open-label randomized controlled trial recruited women aged 22-55 with histologically confirmed Cervical Intraepithelial Neoplasia (CIN) 2 and 3 lesions. Participants were randomly allocated to either thermal ablation or LEEP. All cases were followed up with a Pap smear at three- and six-months post treatment. Sexual health assessments were conducted using a questionnaire at baseline and 3 months post-procedure. Secondary outcome measures included comparison of acceptability, pain, and side effects between the two treatment measures. RESULTS: Out of 1356 screened cases, 60 were included in the study and randomized in two groups. The groups had similar baseline characteristics. Duration of LEEP was longer than thermal ablation (25.33 vs. 20.67 minutes), with higher pain reported 10 minutes post-procedure in the LEEP group. Three months post-procedure, both groups showed comparable acceptability and symptom relief. Sexual function parameters significantly improved in the thermal ablation group compared to LEEP, including satisfaction, desire, lubrication, flexibility, and ability to reach climax. CONCLUSION: LEEP and thermal ablation are effective treatments for CIN with similar efficacy at 6 months. Thermal ablation demonstrated advantages in procedure time and post-procedural pain but exhibited varying effects on sexual function, improving satisfaction and desire. In contrast, LEEP showed a decrease in satisfaction and potential alterations in lubrication and flexibility. Larger-sample, longer-term studies are recommended for further insights.

OBJECTIVE: Cervical conization is an effective treatment for precancerous lesions. However, in cases where no high-grade lesion is identified in the surgical specimen, managing these patients may be challenging due to the absence of established follow-up protocols for negative conizations. This study aimed to assess the negative conization rates at our institution by histopathological review, identify diagnostic errors, possible risk and recurrence factors and propose follow-up strategies for this group of patients. METHODS: A retrospective study from January-2010 to December-2020 analyzed patients with negative conization including all surgical techniques and procedure indications. Biopsy and cervical conizations slides were reviewed and patients who kept a negative result underwent deeper levels sectioning of the paraffin blocks with immunohistochemical stains application: p16, Ki-67 and geminin. Data were compared with a control group composed by 29 women with CIN3. RESULTS: Out of 1022 conizations, 186 were negative (18.1%), with 151 cases selected for the study after excluding 35 patients. Following pathology review, 4 patients were excluded due to false-positive cervical biopsy results, 16 for false-negative conization results and 9 for hidden dysplasia identified after deeper sectioning. The remaining 122 patients were considered truly negative cones (11.9%) and exhibited IHC staining with p16 positive in 20.4% of cases, low Ki-67 expression, and low geminin score in most cases. Specimens with CIN 1 had higher prevalence of p16 staining, Ki-67 expression and geminin score when compared to absence of neoplasia, nevertheless geminin had no statistical difference. Older age, higher parity and IHC pattern with negative p16, low Ki-67 and geminin expressions were identified as risk factors for negative cones (p<0.05). Only 10 patients recurred for high-grade lesions, with no statistically significant risk factors identified. CONCLUSIONS: The negative conization rate was 11.9%, with diagnostic errors identified across pre-surgical biopsy, cone specimen, and deeper levels. Risk factors included older age, higher parity, low expression of p16, Ki-67 and geminin (p<0.05). Recurrence represented 8.1% of the negative cones, without identification of statistically significant risk factors. Pathological review with deeper level sections and 2-year follow-up are recommended for patients with negative conizations.

BACKGROUND: Both the traditional loop electrosurgical excision procedure (LEEP) and the newly developed 5-aminolevulinic acid photodynamic therapy (ALA-PDT) are used to treat high-grade squamous intraepithelial lesions. However, the clinical efficacy and safety of these two therapies have rarely been compared. Thus, this study aimed to compare the clinical efficacy and safety of the two treatment regimens. METHODS: One hundred and twenty patients in two groups (60 + 60) with grade 2 cervical intraepithelial neoplasia (CIN2) were voluntary treated with photodynamic therapy or LEEP between June 2020 and December 2022. Follow-up was conducted at 3, 4-6, and 7-12 months after treatment. RESULTS: Although the total effective rate of LEEP was higher during the first 6 months after treatment, both the total effective rate of lesion degradation and the double-negative rate of high-risk HPV16/18 and liquid-based cervical cytology by ALA-PDT treatment increased with time and finally exceeded those of LEEP at 7-12 months. CONCLUSIONS: ALA-PDT may be more promising than LEEP for treating patients with CIN2 because of the better CIN2 degradation and high-risk HPV negativity, less damage, and greater fertility conservation, especially after 6 months.

OBJECTIVE: To compare the cost-effectiveness of different treatments for cervical intraepithelial neoplasia (CIN). DESIGN: A cost-effectiveness analysis based on data available in the literature and expert opinion. SETTING: England. POPULATION: Women treated for CIN. METHODS: We developed a decision-analytic model to simulate the clinical course of 1000 women who received local treatment for CIN and were followed up for 10 years after treatment. In the model we considered surgical complications as well as oncological and reproductive outcomes over the 10-year period. The costs calculated were those incurred by the National Health Service (NHS) of England. MAIN OUTCOME MEASURES: Cost per one CIN2+ recurrence averted (oncological outcome); cost per one preterm birth averted (reproductive outcome); overall cost per one adverse oncological or reproductive outcome averted. RESULTS: For young women of reproductive age, large loop excision of the transformation zone (LLETZ) was the most cost-effective treatment overall at all willingness-to-pay thresholds. For postmenopausal women, LLETZ remained the most cost-effective treatment up to a threshold of £31,500, but laser conisation became the most cost-effective treatment above that threshold. CONCLUSIONS: LLETZ is the most cost-effective treatment for both younger and older women. However, for older women, more radical excision with laser conisation could also be considered if the NHS is willing to spend more than £31,500 to avert one CIN2+ recurrence.

INTRODUCTION: The role of multiple high-risk human papillomavirus (HR-HPV) infections on the occurrence of persistence/recurrence of high-grade squamous intraepithelial lesion (HSIL) after conization/surgery for cervical intraepithelial neoplasia was evaluated. MATERIAL AND METHODS: A systematic search of Pubmed/Medine, Scopus, Cochrane databases from inception to June 30, 2023 was performed. Three reviewers independently screened the abstracts of the selected studies and extracted data from full-text articles. The data were subsequently tabulated and compared for consistency. The bias associated with each included study was evaluated according to the OSQE method. PROSPERO registration number CRD42023433022. RESULTS: Out of 1606 records screened, 22 full text articles met the inclusion criteria. A total of 8321 subjects treated (loop electrosurgical excision, laser or surgery) because of HSIL were followed-up and included in the meta-analysis. The pooled prevalence of overall persistence and/or recurrence was 17.6 (95% CI: 12.3-23.5) in multiple and 14.3 (95% CI: 10.1-19.2) in single HR-HPV infections detected shortly before or at surgery. The pooled rate of multiple HR-HPV infections was 25% (95% CI: 20.4-30). The odds ratio of histologically confirmed HSIL persistence and/or recurrence was significantly higher (OR: 1.38, 95% CI:1.08-1.75, p = 0.01, heterogeneity = 39%) among multiple than single HR-HPV infections. Increased risk of HSIL persistence/recurrence was more marked among studies with multiple HR-HPVs prevalence ≥25% (12 studies, N = 3476) (OR: 1.47, 95% CI: 1.18-1.84, heterogeneity = 0%) and in those evaluating true histologically confirmed recurrence after at least 6 months of negative follow-up (9 studies, N = 5073) (OR: 1.67, 95% CI: 1.17-2.37, heterogeneity = 37%). Multiple HR-HPVs infection detected during follow-up visits had no effect on the risk of recurrence although the number of included studies was small (4 studies, N = 1248) (OR: 0.98, 95% CI: 0.68-1.39, heterogeneity = 0%). The risk of bias was rated as high in 10 and low-moderate in 12 studies, respectively. In subgroup analysis, the risk of bias of the included studies (low/moderate vs. high), had a small, although not significant effect on the odds ratios of persistence/recurrence of HSIL (OR: 1.57, 95% CI: 1.23-2 for low-moderate risk of bias and OR: 1.06, 95% CI: 0.65-1.75 for high risk of bias; p-value for subgroup differences = 0.17). CONCLUSIONS: Multiple HR-HPVs infections at the time of standard treatment of HSIL entail a small but significant increased risk of persistence/recurrence of HSIL and should be taken into account in the follow-up plan.

OBJECTIVE: The present study aims to evaluate the efficacy and effect of localized delivery of drugs in the treatment of high-grade squamous intraepithelial lesion (HSIL) based on a meta-analysis. STUDY DESIGN: Databases including Cochrane Library, PubMed, Embase, Scopus, CNKI, and Wanfang were searched from their inception till August 2022. Randomized controlled trials (RCTs) that compared the efficacy of drugs and surgery in the treatment of HSIL were collected. A meta-analysis was performed using the software of Review Manager (version 5.4.1). RESULTS: Eight RCTs involving 523 patients were included in the meta-analysis. For HSIL, the rate of cervical lesions histological regression was 69.85 % in the surgery group and 59.88 % in the drug group, there was no significant difference between the two groups [OR = 0.45, 95 % CI (0.07, 3.03), P = 0.41]. The histological regression rate of cervical lesions in the placebo group was 37.76 %, and the difference between the drug group and the placebo group was statistically significant [OR = 4.94, 95 % CI (2.65, 9.20), P < 0.00001]. CONCLUSION: A total of four drugs were involved in the eight RCTS included in this study, which were imiquimod, 5-fluorouracil (5-FU), cidofovir and interferon. The results showed that although drug administration was effective in the histological regression of HSIL, the efficacy was less than about 10% of surgical treatment. Considering the recurrence of the disease after surgery and the problems of abortion, premature delivery and premature rupture of membranes after cervical conization in reproductive women, drug therapy can be used as a supplement to surgery or conservative treatment to promote the histological regression of cervical lesions in patients with HSIL.

BACKGROUND: HPV is detected in up to 47% of CIN and up to 70% of cervical cancers. It can cause intraepithelial neoplasia, which can eventually progress to invasive carcinoma. Almost all cervical cancers are caused by HPV. Therefore, it is especially important to treat high-risk HPV. For patients who have undergone LEEP surgery, this procedure can effectively treat CIN. However, it has not been studied in a meta-analysis whether HPV remains after the surgery and whether residual HPV increases the recurrence risk of CIN. To address this gap, our study collected all relevant literature to investigate the residual rate of HPV and its potential influence on the recurrence rate of CIN. We aim to provide valuable recommendations for clinicians and patients. METHODS: The Cochrane Library, EMBASE, and PubMed databases were searched from the establishment of the database until October 2023. Stata 12.0 software was used for the statistical analysis. RESULTS: Twelve studies were included, with a total sample size of 1192 cases. The meta-analysis found that the recurrence rate of CIN was quite low [95% CI = 0.5% (0.001, 0.012); P = 0.006] when the margins were negative after LEEP and there was no residual HPV. When HPV was present, the recurrence rate of CIN was significantly higher [95% CI = 18% (0.089, 0.291), P = 0.000], even if the margins were negative. The recurrence rate of CIN with residual HPV was 3.6 times higher than the recurrence rate of CIN without residual HPV. The residual rate of HPV after LEEP with negative margins was 22.7% [95% CI (0.167, 0.294), P = 0.000], which remained relatively high. CONCLUSION: This meta-analysis found that the recurrence rate of CIN without residual HPV and with negative margins after LEEP was quite low, at 0.5%. However, when HPV was residual, the recurrence rate of CIN significantly increased to 18%, even if the margins were negative. The residual rate of HPV was 22.7%, even when the margins were negative after LEEP.
