Clinical analysis of 314 patients with high-grade squamous intraepithelial lesion who underwent total hysterectomy directly: a multi-center, retrospective cohort study.

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.

Reevaluation of negative cervical conizations: Frequency, diagnostic errors, risk factors and management.

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.

The role of multiple high-risk human papillomavirus infection on the persistence recurrence of high-grade cervical lesions after standard treatment: A systematic review and a meta-analysis.

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.

Factors associated with the persistence of human papillomavirus after surgery in patients with cervical cancer.

OBJECTIVE: To determine the rate of human papillomavirus (HPV) persistence after surgery in patients with cervical cancer, and to analyze the factors associated with HPV persistence and viral load after surgery. METHODS: Medical records of women who underwent surgery for treatment of cervical cancer between 1 January 2018 and 30 June 2019 at Obstetrics and Gynecology Hospital of Fudan University in Shanghai, China, were retrospectively analyzed. Patients with persistent HPV infection after 2 years of follow-up were identified. Univariate and multivariate analyses were employed to determine the impact of various factors including patient age, menopausal status, parity, and surgical margin status on HPV persistence. The Wilcoxon test was used to analyze the factors that influenced postoperative HPV viral load. RESULTS: Altogether, 607 women were eligible for the final analysis. The persistence rates of HPV at 6 months, 1 year, and 2 years after surgery were 17.3, 13.7, and 10.2 %, respectively. In univariate analysis, the factors that were predictive of the persistence of HPV infection were old age, postmenopausal status, and positive vaginal incision margin with cancer. In multivariate analysis, the significant independent predictive factors were postmenopausal status and positive vaginal incision margin with cancer (P < 0.05, odds ratio (OR) = 2.289, 95 % confidence interval (CI): 1.262-4.150 and OR = 3.271, 95 % CI: 1.253-8.537, respectively). A vaginal lesion with cancer or squamous intraepithelial lesion (SIL) and positive vaginal incision margin influenced HPV viral load at 6 months after surgery (P < 0.05). CONCLUSIONS: Postmenopausal patients and those with positive vaginal incision margin with cancer are at an increased risk of HPV persistence after surgical treatment for cervical cancer. Vaginal lesions with cancer or SILs and positive vaginal incision margin are risk factors for high HPV viral load after surgery.

Adenocarcinoma In Situ of the Uterine Cervix (AIS) Treated by Loop Electrosurgical Excision Procedure Strategy: An Observational Study.

OBJECTIVES: Evaluation of the results of treatment of adenocarcinoma in situ by loop electrosurgical excision procedure and the safety of a conservative strategy. METHODS: Identification of all cases of adenocarcinoma in situ treated by loop electrosurgical excision procedure at our institution and follow-up by a conservative strategy. Completeness of the identification of all cases was secured by data from the National Pathology Registry. The treatment strategy was based on cytologic follow-up performed by a general practitioner and, irrespective of margin status of the cone, only the results of the postoperative surveillance were indicative of further treatment. RESULTS: A total of 224 patients were identified. The overall recurrence rate with a mean follow-up time of 87.8 months was 7.6% (17/224). The recurrence rate in patients with involved margins was significantly higher than in patients with uninvolved margins, 15.7% vs 5.2%, respectively. Six recurrences were diagnosed at first examination 6 months postconization in patients with involved margins. They were treated with hysterectomy in 4 cases and reconization in 1 case. If involvement of margins alone had been an indication of further therapy (hysterectomy or reconization) immediately after conization, the conservative management strategy prevented 46 surgical procedures. Two cases of invasive cancer were diagnosed during follow-up, 150 months and 196 months after primary treatment, and after normal follow-up examinations. These 2 cases must be considered de novo cases and cannot be considered treatment failures. CONCLUSION: The conservative management strategy thus seems safe, and unnecessary surgical procedures were avoided.

Aesthetic Outcome and Psychosexual Distress After Treatment for Vulvar High-Grade Squamous Intraepithelial Lesions.

OBJECTIVES: This study compared aesthetic outcome, psychosexual distress, and treatment satisfaction between women receiving surgical treatment or medical treatment with imiquimod for vulvar high-grade squamous intraepithelial lesion. MATERIALS AND METHODS: This is an extended analysis of the multicenter, randomized noninferiority trial "topical imiquimod versus surgery for vulvar intraepithelial neoplasia." Patients were randomized to primary topical treatment or surgery and stratified by unifocal or multifocal disease. Digital photos of vulvar appearance were subsequently assessed for aesthetic outcome by 3 investigators blinded to group allocation. Psychosexual distress and treatment satisfaction were assessed with the Cervical Dysplasia Distress Questionnaire, the Sexual Activity Questionnaire, and the Client Satisfaction Questionnaire at baseline and follow-up. RESULTS: One hundred ten patients aged between 19 and 82 years were enrolled. Per-protocol analysis showed complete clinical response in 80% (37/46) using imiquimod, compared with 79% (41/52) after one surgical intervention. Photodocumentation at baseline and 6-month follow-up was available for 84 of these patients (44 imiquimod, 40 surgery). Blinded reviewer assessments of lesion size and lesion severity showed improvement from baseline to follow-up, with no differences between treatment groups. Sexual pleasure, discomfort, and distress remained stable from baseline to follow-up in both groups. CONCLUSIONS: Good aesthetic outcome of vulvar high-grade squamous intraepithelial lesion treatment can be achieved with imiquimod and surgery, consisting of ablation or local excision. Treatment satisfaction and stable psychosexual health may not be dependent on chosen treatment modality, but rather on counseling in accordance with patients' preferences.

Margin status after loop electrosurgical excision procedure (LEEP) and laser excision in patients with high-grade cervical neoplasia.

INTRODUCTION: Early management of high-grade cervical intraepithelial neoplasia is one of the key steps in cervical cancer prevention after vaccination and screening. It relies on lesion removal by surgical excision, and the French National Cancer Institute (INCa) in 2016 recommend using a loop electro excision procedure (LEEP). However, the laser excision method seems to be as effective with similar rates of negative excision margins and postoperative clearance of HPV. OBJECTIVE: The main objective of our study was to compare the laser excision method to LEEP by evaluating the quality of the surgical margins. We also studied factors associated with the status of the margins and the depth of cones. METHODS: We conducted a retrospective unicentric study between 2009 and 2017. RESULTS: Two hundred and thirty-one patients were included: 154 laser excisions and 77 LEEP. Negative surgical margin was achieved in 69.5 % of laser excisions and 72.7 % of LEEP (p = 0.649). Concerning factors predicting margin status, only a greater cone depth was associated with negative margins (OR: 0.91 (95 %CI: 0.84, 0.89); p = 0.02). The surgical technique was not found to be associated with the status of the margins (OR: 0.85 (95 %CI: 0.46,1.56); p = 0.61). Concerning factors predicting cone depth, only the LEEP was associated with a shorter cone depth (OR: 0.24 (95 %CI: 0.08, 0.69); p 0.008). Significant results are based on univariate analysis. CONCLUSION: No difference was found between the two technics concerning the rate of negative margins. However, LEEP seems to be associated with shorter cone depth in this study.

HPV-related lesions after hysterectomy for high-grade cervical intraepithelial neoplasia and early-stage cervical cancer: A focus on the potential role of vaccination.

OBJECTIVE: To date, no data supports the execution of vaccination after hysterectomy for high-grade cervical intraepithelial neoplasia (CIN2+) and early-stage cervical cancer. We aim to evaluate the potential effect of vaccination after hysterectomy for high-grade cervical intraepithelial neoplasia and early-stage cervical cancer. METHODS: This is a multi-center retrospective study evaluating data of women who develop lower genital tract dysplasia (including anal, vulvar and vaginal intra-epithelial neoplasia) after having hysterectomy for CIN2+ and FIGO stage IA1- IB1 cervical cancer. RESULTS: Overall, charts for 77 patients who developed lower genital tract dysplasia were collected. The study population included 62 (80.5%) and 15 (19.5%) patients with CIN2+ and early-stage cervical cancer, respectively. The median (range) time between hysterectomy and diagnosis of develop lower genital tract dysplasia was 38 (range, 14-62) months. HPV types covered by the nonavalent HPV vaccination would potentially cover 94.8% of the development of lower genital tract dysplasia. Restricting the analysis to the 18 patients with available HPV data at the time of hysterectomy, the beneficial effect of nonvalent vaccination was 89%. However, considering that patients with persistent HPV types (with the same HPV types at the time of hysterectomy and who developed lower genital tract dysplasia) would not benefit from vaccination, we estimated the potential protective effect of vaccination to be 67% (12 out of 18 patients; four patients had a persistent infection for the same HPV type(s)). CONCLUSIONS: Our retrospective analysis supported the adoption of HPV vaccination in patients having treatment for HPV-related disease. Even in the absence of the uterine cervix, HPV vaccination would protect against develop lower genital tract dysplasia. Further prospective studies have to confirm our preliminary research.

Correlation Between Persistent HPV Infection and Vaginal Microecological Imbalance After Treatment of Cervical High-Grade Squamous Intraepithelial Lesion.

Objective: To analyze the association between persistent human papillomavirus (HPV) infection and vaginal microecological imbalance after surgical treatment of cervical high-grade squamous intraepithelial lesion (HSIL). Methods: This is a retrospective study, 180 cervical HSIL patients admitted to our hospital from May 2019 to May 2021 were selected, of these, 84 were treated with loop electrosurgical excision procedure (LEEP) and 96 with cold knife conization (CKC). Patients were followed up for HPV infection 1 year after surgery. There is a division into a persistent infection group (positive group) and a negative group based on the presence or absence of HPV, the detection technique was PCR amplification. The two groups were compared regarding preoperative HPV infection, vaginal micro-ecological indicators 1 year after surgery, and the correlation between persistent HPV infection and vaginal microecological imbalance. Results: At 1 year after surgery, among 180 cervical HSIL patients, 64 (35.56%) were persistently infected with HPV, with an age of (40.20 ± 4.85) years, including 36 (56.25%) with cervical intraepithelial neoplasia (CIN) grade II, 28 (43.75%) with cervical intraepithelial neoplasia (CIN) grade III, 116 (64.44%) with HPV negative, with an age of (40.22 ± 5.15) years, including 67 (57.76%) with CIN grade II and 49 (42.24%) with CIN grade III, the differences in age and CIN classification between the two groups were not statistically significant (P > .05). Preoperatively, 53 people (82.81%) with HPV viral load >100 RLU/CO in the HPV persistent infection group and 76 people (65.52%) with HPV viral load >100 RLU/CO in the HPV negative group, with statistically significant differences between the two groups (P < .05); The difference in HPV virus typing and HPV infection type between the two groups was not statistically significant (P > .05). At 1 year after surgery, the composition ratio of flora density class IV and flora diversity class IV were significantly higher in the HPV persistent infection group than in the HPV negative group, and the dominant bacteria were mainly gram-positive large bacillus, accounting for 83.33%, the difference between the two groups was statistically significant (P < .05); The differences in Nugent scores and pH values between the two groups were not statistically significant (P > .05). Logistic regression analysis showed that flora density, flora diversity, and dominant bacteria were all independent risk factors for persistent HPV infection after treatment in patients with HSIL (P < .05). Conclusion: After treatment of HSIL patients, clinical attention should be paid to monitoring of HPV infection but also to the changes in vaginal microecology, as timely correction of vaginal microecology can facilitate HPV regression and improve the patient's prognosis.

A Comprehensive Program to Improve Treatment of Precancerous Cervical Lesions in the Rio Grande Valley of Texas.

OBJECTIVE: To assess the impact of a multicomponent intervention in women with cervical dysplasia who were treated with loop electrosurgical excision procedure (LEEP), as well as the time between colposcopy and treatment. DESIGN: Retrospective cohort study. INTERVENTION: Clinic participation in a multicomponent cervical cancer prevention program that included community outreach, patient in-reach, and navigation, as well as provider capacity building with in-person training and ongoing telementoring through Project ECHO. MAIN OUTCOME MEASURES: Medical records were reviewed to evaluate women with cervical dysplasia undergoing treatment with LEEP within 90 days of colposcopy, as well as time between colposcopy and treatment. Baseline data from year 1 were compared with each subsequent year of implementation. Additional variables examined included patient's age, history of abnormal screening results, and percentage of families living below poverty line based on county of residence, parity, and clinic site. We performed logistic regression and multiple linear regression analyses to assess the programmatic impact in the outcomes of interest by year of program implementation. RESULTS: A total of 290 women were included in the study. The proportion of women undergoing treatment within 90 days of colposcopy increased from 76.2% at baseline to 91.3% in year 3 and 92.9% in year 4 of program implementation. The odds of undergoing treatment within 90 days were 5.11 times higher in year 4 of program implementation than at baseline. The mean time between colposcopy and LEEP decreased from 62 days at baseline to 45 days by year 4 of program implementation. CONCLUSIONS: Implementation of our multicomponent cervical cancer prevention program increased the proportion of women undergoing LEEP within 90 days of colposcopy and decreased the time between colposcopy and LEEP. This program has the potential to support cervical cancer prevention efforts and could be implemented in other low-resource settings.

HPV E6/E7 mRNA combined with thin-prep cytology test for the diagnosis of residual/recurrence after loop electrosurgical excision procedure in patients with cervical intraepithelial neoplasia.

To evaluate the diagnostic value of combining HPV E6/E7 mRNA testing with Thin-Prep cytology (TCT) for residual/recurrence detection, a total of 289 patients who underwent loop electrosurgical excision procedure (LEEP) for high-grade cervical lesions were included. Patients were followed up at different time points, and residual/recurrent lesions were confirmed through vaginoscopy. TCT, HPV-DNA, and HPV E6/E7 mRNA tests were conducted. Diagnostic performance, including sensitivity, specificity, positive predictive value, negative predictive value, and accuracy, was assessed. Among the patients, 76 cases showed residual lesions/recurrence, while 213 cases showed no residual/recurrence. Positive margins in the cervical-vaginal and cervical canal areas were associated with a higher risk of residual/recurrence. The combined HPV E6/E7 mRNA and TCT test showed higher diagnostic efficacy than individual tests at 6-, 12-, and 24-months follow-up. The combined test consistently demonstrated higher specificity and sensitivity, with significantly larger area under the curve (AUC) values compared to the individual tests.

Handheld vital microscopy for the identification of microcirculatory alterations in cervical intraepithelial neoplasia and cervical cancer.

BACKGROUND: Ninety percent of cervical cancer (CC) diagnoses and deaths occur in low and middle-income countries (LMICs). Especially in these countries, where human and material resources are limited, there is a need for real-time screening methods that enable immediate treatment decisions (i.e., 'see and treat'). OBJECTIVE: To evaluate whether handheld vital microscopy (HVM) enables real-time detection of microvascular alterations associated with cervical intraepithelial neoplasia (CIN) and CC. METHODS: A cross-sectional study was conducted in an oncologic hospital and outpatient clinic, and included ten healthy controls, ten women with CIN, and ten women with CC. The microvasculature was assessed in four quadrants of the uterine cervix using HVM. The primary outcome was the presence of abnormal angioarchitecture (AA). Secondary outcomes included capillary loop density (CD), total vessel density (TVD), functional capillary density (FCD), and the proportion of perfused vessels (PPV). RESULTS: 198 image sequences of the cervical microvasculature were recorded. Compared to healthy controls, significantly more abnormal image sequences were observed in women with high-grade CIN (11 % vs. 44 %, P < 0.001) and women with CC (11 % vs. 69 %, P < 0.001). TVD, FCD, and PPV were lower in women with CIN and CC. CONCLUSIONS: HVM enables easy, real-time, non-invasive assessment of cervical lesions through the detection of microvascular alterations. Thereby, HVM potentially provides an opportunity for point-of-care screening, which may enable immediate treatment decisions (see and treat) and reduce the number of unnecessary surgical interventions.

Abnormal Vaginal Cytology after Total Laparoscopic Hysterectomy in Patients with Cervical Intraepithelial Neoplasia.

To explore the incidence of abnormal vaginal cytology after total laparoscopic hysterectomy for the treatment of cervical intraepithelial neoplasia 3, we retrospectively analyzed the medical records of patients treated at NHO Shikoku Cancer Center (Japan) in 2014-2019. The cases of 99 patients who underwent a laparoscopic (n=36) or open (n=63) hysterectomy and postoperative follow-up were examined. Abnormal vaginal cytology was detected in 13.9% (5/36) of the laparoscopic-surgery (LS) group and 14.3% (9/63) of the open-surgery (OS) group. A vaginal biopsy was performed at the physicians' discretion; one LS patient and six OS patients were diagnosed with vaginal intraepithelial neoplasia. The cumulative incidence of abnormal vaginal cytology at 3 years post-hysterectomy was 21.4% (LS group) and 20.5% (OS group), a nonsignificant difference. A multivariate analysis showed that age > 50 years was the only independent risk factor for abnormal vaginal cytology among the covariates examined including age; body mass index; histories of vaginal delivery, abdominal surgery, and smoking; and surgical approach (hazard ratio 8.11; 95% confidence interval 1.73-37.98; p=0.01). These results suggest that the occurrence of abnormal vaginal cytology after a hysterectomy may not be influenced by the laparoscopic procedure but is associated with older age.

Emergency hysterectomy following iatrogenic injury to the descending branch of the uterine artery during colposcopy.

Large loop excision of the transformation zone is an extremely common procedure routinely carried out in a gynaecology or colposcopy outpatient setting under local anaesthetic. Here, we present a rare case resulting in emergency hysterectomy. A healthy para 3, who had been diagnosed with microscopic cancer of the cervix, attended colposcopy for repeat excision. The colposcopy revealed a normal cervix, and diathermy loop excision was performed. During the procedure, heavy bleeding from the anterior cutting edge was noted. Despite the best attempts to manage the haemorrhage conservatively in outpatients, the bleeding persisted, and the patient was transferred to theatres. Examination under anaesthesia revealed an injury to the descending branch of the uterine artery, and emergency hysterectomy was performed. Immediate recognition of an extremely rare complication, fast decision-making and a cross-disciplinary approach led to a satisfactory outcome.

Comparison of acceptability & efficacy of thermal ablation (thermocoagulation) & cryotherapy in VIA positive cervical lesions: A pilot study.

BACKGROUND OBJECTIVES: The World Health Organization (WHO) has endorsed thermal ablation (thermocoagulation) as an efficient and safe modality for treatment of cervical pre-cancer lesions. More evidence is being looked up by WHO through rigorous studies for health delivery models using screen-and-treat strategies incorporating thermal ablation and studies comparing it against the conventional standard modality cryotherapy. The objective of this study was to assess the acceptability of thermal ablation both among the providers and clients and compare the same with cryotherapy. METHODS: A randomized control trial was conducted for one year from September 2019 to October 2020 after obtaining ethics approval. Computer-generated random number table was used for randomization, and eligible candidates were divided into two groups following informed consent. Women with visual inspection with acetic acid (VIA) positive cervical lesions in Group A received cryotherapy and Group B received thermal ablation. After the procedure, the acceptability of the provider and the client were assessed using the International Agency for Research on Cancer-validated questionnaire for both the procedures. Immediate side effects and problems at six weeks and at six months were assessed as well. Efficacy was decided by the absence of VIA positivity at six months. RESULTS: The overall VIA positivity in this study was 11.8 per cent. Thermal ablation (thermocoagulation) had better provision and client acceptability than cryotherapy (significant difference). The efficacy of thermal ablation was 97.6 per cent, while, it was 92 per cent for cryotherapy (not significant). INTERPRETATION CONCLUSIONS: In the context of screen-and-treat programme in settings such as India, thermal ablation appears to be a better method of treatment than cryotherapy for cervical pre-cancerous lesions particularly in terms of better provision and client acceptability.

How to make a LLETZ simulator: LLETZ Simulator.

Large loop excision of the transformation zone (LLETZ) of the uterine cervix is a surgical procedure very frequently performed. Simulation of LLETZ under colposcopic guidance has a major role in training practitioners. The objective was to present an ex vivo model of LLETZ.

Efficacy of recombinant bovine basic fibroblast growth factor to reduce hemorrhage after cervical loop electrosurgical excision procedure.

OBJECTIVE: It has been reported that recombinant bovine basic fibroblast growth factor (rbFGF) may possess possible biological functions in promoting the process of wound healing. Consequently, our study aimed to investigate the hemostatic effect of topically applied rbFGF in patients who underwent a loop electrosurgical excision procedure (LEEP). METHODS: In this retrospective analysis, we meticulously examined clinicopathologic data from a cohort of 90 patients who underwent LEEP at our institution between 2020 and 2021. Subsequently, we conducted inquiries with the patients to ascertain the degree of vaginal bleeding experienced during the postoperative periods of 3 and 6 weeks, comparing it to their preoperative menstrual flow. The magnitude of the menstrual volume alteration was then quantified using a menstrual volume multiplier(MVM). The primary endpoints of our investigation were to assess the hemostatic effect of rbFGF by means of evaluating the MVM. Additionally, the secondary endpoints encompassed the assessment of treatment-related side effects of such as infection and dysmenorrhea. RESULTS: Our findings demonstrated a significant reduction in hemorrhage following cervical LEEP. Specifically, in the per-protocol analysis, the study group exhibited a statistically significantly decrease in MVM after 3 weeks (0 [0-0] vs. 1 [0-1], respectively; p < 0.001) and after 6 weeks (1 [1] vs. 2 [1-3], respectively; p < 0.001) of the procedure. No notable disparities were observed in the remaining outcomes between the two groups. Moreover, a logistic regression analysis was employed to explore the relationship between significant bleeding and rbFGF treatment (p < 0.001, OR = -2.47, 95% CI -4.07 ~-1.21), while controlling for confounding factors such as age, BMI, and surgical specimen. CONCLUSIONS: In conclusion, our study findings highlight that the application of recombinant bovine basic fibroblast growth factorcan effectively mitigate hemorrhage subsequent to cervical loop electrosurgical excision procedure.

Non-Excisional therapeutic modalities in vaginal intraepithelial neoplasia.

Vaginal intraepithelial neoplasia is an uncommon Human Papilloma Virus-related premalignant lesion of the lower genital tract. There is still no consensus regarding its management. Therapeutic modalities include observation, laser ablation, topical agents, radiation and surgical approach. Due to the current increasing adherence to minimally invasive therapies the aim of this study is to identify and characterize non-excisional treatment modalities. Expectant management is the first therapeutical option in low-grade lesions management. Up to 81% of lesions through an expectant approach regressed spontaneously and most of them were low-grade lesions. In contrast, high-grade lesions, due to its higher potential to invasion progression and low regression rate, require treatment, which should be selected depending on its characteristics and the patient's preference. Laser ablation is suitable for multifocal lesions in sexually active young women with a cure rate up to 90% and recurrence rate up to 6.3%. Brachytherapy can be 71.4%-90% efficient with a maximum of 5.8% and 20% of persistence rate and recurrence rate, respectively. However, due to its toxicity, it should be reserved for selected cases only. Topical modalities for multifocal lesions, such as Imiquimod 5% and 5-Flouorouracil, have a good therapeutic effect, low pharmacological morbidity, and 25%-98% cure rate, 11.1%-75% persistence rate and 5.6%-94.4% recurrence rate.
