RESUMO

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.

RESUMO

INTRODUCTION: Men who have sex with men (MSM), especially those living with HIV, are at an increased risk of anal cancer. The prevalence and incidence of its precursor, anal high-grade squamous intraepithelial lesions (HSILs), among MSM who started antiretroviral therapy during acute HIV acquisition are yet to be explored. METHODS: Participants in an acute HIV acquisition cohort in Bangkok, Thailand, who agreed to take part in this study, were enrolled. All participants were diagnosed and started antiretroviral therapy during acute HIV acquisition. Human papillomavirus (HPV) genotyping and high-resolution anoscopy, followed by anal biopsy as indicated, were done at baseline and 6-monthly visits. RESULTS: A total of 89 MSM and four transgender women were included in the analyses. Median age at enrolment was 26 years. Baseline prevalence of histologic anal HSIL was 11.8%. With a total of 147.0 person-years of follow-up, the incidence of initial histologic anal HSIL was 19.7 per 100 person-years. Factors associated with incident anal HSIL were anal HPV 16 (adjusted hazards ratio [aHR] 4.33, 95% CI 1.03-18.18), anal HPV 18/45 (aHR 6.82, 95% CI 1.57-29.51), other anal high-risk HPV (aHR 4.23, 95% CI 1.27-14.14), syphilis infection (aHR 4.67, 95% CI 1.10-19.90) and CD4 count <350 cells/mm3 (aHR 3.09, 95% CI 1.28-7.48). CONCLUSIONS: With antiretroviral therapy initiation during acute HIV acquisition, we found the prevalence of anal HSIL among cisgender men and transgender women who have sex with men to be similar to those without HIV. Subsequent anal HSIL incidence, although lower than that of those with chronic HIV acquisition, was still higher than that of those without HIV. Screening for and management of anal HSIL should be a crucial part of long-term HIV care for all MSM.

RESUMO

Anal intraepithelial neoplasia (AIN) are precancerous lesions and are sequela of human papilloma virus (HPV) infection. AIN is classified as low-grade squamous intraepithelial lesion or high-grade squamous intraepithelial lesion. Screening with anal cytology and anoscopy should be considered for high-risk populations. Diagnosis is made through high resolution anaoscopy and biopsy. Options for treatment include ablation and several topical therapies; however, recurrence rates are high for all treatment options, and an ongoing surveillance is necessary to prevent progression to anal squamous cell carcinoma. HPV vaccination is recommended to prevent disease.

RESUMO

INTRODUCTION: High-resolution anoscopy (HRA) is the gold standard for detecting anal squamous cell carcinoma (ASCC) precursors. Preliminary studies on the application of artificial intelligence (AI) models to this modality have revealed promising results. However, the impact of staining techniques and anal manipulation on the effectiveness of these algorithms has not been evaluated. We aimed to develop a deep learning system for automatic differentiation of high-grade squamous intraepithelial lesion vs low-grade squamous intraepithelial lesion in HRA images in different subsets of patients (nonstained, acetic acid, lugol, and after manipulation). METHODS: A convolutional neural network was developed to detect and differentiate high-grade and low-grade anal squamous intraepithelial lesions based on 27,770 images from 103 HRA examinations performed in 88 patients. Subanalyses were performed to evaluate the algorithm's performance in subsets of images without staining, acetic acid, lugol, and after manipulation of the anal canal. The sensitivity, specificity, accuracy, positive and negative predictive values, and area under the curve were calculated. RESULTS: The convolutional neural network achieved an overall accuracy of 98.3%. The algorithm had a sensitivity and specificity of 97.4% and 99.2%, respectively. The accuracy of the algorithm for differentiating high-grade squamous intraepithelial lesion vs low-grade squamous intraepithelial lesion varied between 91.5% (postmanipulation) and 100% (lugol) for the categories at subanalysis. The area under the curve ranged between 0.95 and 1.00. DISCUSSION: The introduction of AI to HRA may provide an accurate detection and differentiation of ASCC precursors. Our algorithm showed excellent performance at different staining settings. This is extremely important because real-time AI models during HRA examinations can help guide local treatment or detect relapsing disease.

RESUMO

BACKGROUND: Anal squamous intraepithelial lesions (ASILs) correspond to premalignant changes preceding the development of anal squamous cell carcinoma. OBJECTIVE: To describe a new endoscopic technique to detect and remove ASILs in non-anesthetized patients and compare it with standard surgical treatment. METHODS: For endoscopic treatment, high resolution (HR) flexible endoscopes with a distal attachment were used. Underwater inspection of the anal canal was performed in near-focus mode with white light and narrow-band imaging. Detected lesions were resected with a diathermia snare after local injection of xylocaine/adrenaline. We did a retrospective comparison of all patients who underwent endoscopic or standard surgical treatment for ASILs at Ersta hospital in Stockholm between 2018 and 2020. Patient files were reviewed for number of lesions, treatments until macroscopic radicality, degree of dysplasia, bleeding, pain and other complications. RESULTS: Endoscopic (n = 37) and surgical (n = 43) treatment displayed comparable number of lesions per patient (p = .37). The number of procedures until macroscopic radicality was higher for endoscopy than surgery (p = .04). However, in endoscopic follow up of 12 of the surgically treated patients, residual ASIL was found in 10 cases. Post-procedural bleeding requiring healthcare occurred in two endoscopy patients and one surgically treated patient. CONCLUSIONS: Underwater resection using a HR flexible endoscope in non-anesthetized is a new, feasible and well tolerated method for ASILs treatment. Its efficacy and risk of complications seem comparable to standard surgical treatment while avoiding general anesthesia. However, minor lesions might be overlooked at surgery.

RESUMO

BACKGROUND: Ablation or surgical excision is the typical treatment of anal high-grade squamous intraepithelial lesions (HSIL). Recurrences are common due to the persistence of underlying human papillomavirus (HPV) infection. Additional well-tolerated and effective non-surgical options for HPV-associated anal disease are needed. METHODS: This 3+3 dose escalation Phase I clinical trial evaluated the safety and tolerability of artesunate suppositories in the treatment of patients with biopsy-proven HSIL. RESULTS: The maximal tolerated dose was 400 mg, administered in 3 cycles. All adverse events associated with the use 200- and 400-mg artesunate suppositories were Grade 1. At the 600-mg dose, patients experienced clinically significant nausea. CONCLUSION: Artesunate suppositories are a safe treatment option for anal HSIL.

RESUMO

BACKGROUND: The detection and continuous monitoring of low-grade squamous intraepithelial lesions (LSIL) within the endocervical canal pose considerable challenges, and the effectiveness of ablation treatment is also constrained. In this context, the potential efficacy of 5-aminolevulinic acid photodynamic therapy (5-ALA PDT) in targeting these concealed lesions merits exploration. The present study undertakes a comprehensive analysis of the clinical effectiveness and safety aspects associated with the utilization of 5-ALA PDT. METHODS: A retrospective analysis was conducted on a cohort of 13 patients who were diagnosed with LSIL within the endocervical canal, concomitant with high-risk human papillomavirus (hrHPV) infection. These patients were subjected to treatment with 5-ALA PDT and subsequently monitored over a period of 3-6 months following the intervention. RESULTS: The study cohort comprised 13 patients, among whom 4 presented with isolated lesions within the endocervical canal, 5 exhibited LSIL involving both the endocervical canal and the cervix vaginal portion, 3 displayed LSIL within the endocervical canal in conjunction with vaginal involvement, and 1 patient demonstrated lesions across all three of these anatomical sites. All identified lesions underwent therapeutic intervention via 5-ALA PDT. Before treatment initiation, 9 patients returned positive results in the liquid-based cytologic test (LBC), 4 displayed concurrent multiple hrHPV infections, and 5 manifested infections specifically with HPV 16/18. Subsequent to the application of 5-ALA PDT, regression was observed in the LBC results of all patients, with only 3 individuals retaining a singular type of hrHPV infection. Adverse reactions following treatment encompassed mild aberrant vaginal secretions and mild to moderately pronounced distending abdominal discomfort, all of which were remitted within a span of 7 days. CONCLUSIONS: Within the context of LSIL within the endocervical canal in association with hrHPV infection, the findings affirm the efficacy and safety of 5-ALA PDT as a viable therapeutic modality.

RESUMO

OBJECTIVES: To evaluate the clinical efficacy of thermocoagulation in women with biopsy-confirmed cervical low-grade squamous intraepithelial lesions (LSIL) or less after colposcopy referral. MATERIAL AND METHODS: A longitudinal study was performed. Women who were diagnosed with cervical LSIL or chronic cervicitis underwent scheduled follow-up examinations with cytology and human papilloma virus (HPV) genotyping for two years after the initial management with thermocoagulation or observation without treatment. All women underwent scheduled follow-up with combined cytology and HPV test at 6th months, 12th months, and 24th months after the initial management. Both HPV clearance and cytological regression were included in the analysis, with clinical cure defined as normal cytology and negative HPV results. RESULTS: A total of 221 women were included. The histopathological results identified 136 (61.54%) patients with LSIL and 85 (38.46%) with chronic cervicitis. Of these, 113 (51.13%) received thermocoagulation therapy, and 108 (48.87%) chose observation. The 2-year follow-up rate was 91.40%. Women who received thermocoagulation presented a significantly higher probability of cure for two years than those who chose observation (62.86% vs 39.18%, p < 0.001). This preponderance was not observed in the subgroup analysis regarding women with cervical cervicitis (54.17% vs 41.38%, p = 0.277) but was observed in women with LSILs (70.18% vs 38.24%, p < 0.001). CONCLUSIONS: Thermocoagulation may be indicated for patients with cervical LSILs as an effective outpatient procedure in clinical practice.

RESUMO

Objective: To investigate the natural regression and related factors of high-grade squamous intraepithelial lesion (HSIL) in the cervix of childbearing age women, and to evaluate the applicability of conservative management for future fertility needs. Methods: This study included 275 patients of reproductive age with fertility needs, who were diagnosed as HSIL by biopsy from April 30, 2015 to April 30, 2022, including 229 cases (83.3%) cervical intraepithelial neoplasia (CIN) Ⅱ and 46 cases (16.7%) CIN Ⅱ-Ⅲ. They were followed-up without immediate surgery in the First Affiliated Hospital of Nanjing Medical University. The median follow-up time was 12 months (range: 3-66 months). The regression, persistence and progression of lesions in patients with HSIL were analyzed during the follow-up period, the influencing factors related to regression and the time of regression were analyzed. Results: (1) Of the 275 HSIL patients, 213 cases (77.5%, 213/275) experienced regression of the lesion during the follow-up period. In 229 CIN Ⅱ patients, 180 cases (78.6%) regressed, 21 cases (9.2%) persisted, and 28 cases (12.2%) progressed. In 46 CIN Ⅱ-Ⅲ patients, 33 cases (71.7%) regressed, 12 cases (26.1%) persisted, and 1 case (2.2%) progressed to invasive squamous cell carcinoma stage Ⅰ a1. There was no significant difference in the regression rate between the two groups (χ2=1.03, P=0.309). (2) The average age at diagnosis, age <25 years old at diagnosis were independent influencing factor of HSIL regression in univariate analysis (all P<0.05). There was no significant difference between HSIL regression and pathological grading, the severity of screening results, human papillomavirus (HPV) genotype, colposcopy image characteristics, number of biopsies during follow-up and pregnancy experience (all P>0.05). (3) The median regression times for patients aged ≥25 years and <25 years at diagnosis were 15 and 12 months, respectively. Kaplan-Meier analysis showed that age ≥25 years at diagnosis significantly increased the median regression time compared to <25 years (χ2=6.02, P=0.014). Conclusions: For HSIL patients of childbearing age, conservative management without immediate surgical intervention is preferred if CINⅡ is fully evaluated through colposcopy examination. Age ≥25 years at diagnosis is a risk factor affecting the prognosis of HSIL patients.

RESUMO

Background: Stem cells exist in niches in the cervical tissue at squamocolumnar junction, which when infected with HR-Human Papilloma Virus undergo malignant transformation to cancer stem cells and have a role in carcinogenesis and metastasis. The expression of CD44, P16, and Ki67 in high-grade squamous intraepithelial lesion (HSIL) and squamous cell carcinoma (SCC) is assessed in this study. Materials and Methods: Twenty-six cases each of normal cervix, HSIL, and SCC of cervix cases were subjected to immunohistochemistry markers; p16, Ki-67, and CD44. The association of expression of these markers between normal, HSIL, SCC cervix, and clinic-pathological parameters was statistically analyzed. P < 0.05 was considered significant. Results: Of 26 cases of HSIL, 61.5%, 7.7%, and 30.8% cases were positive, ambiguous, and negative respectively for p16 expression. About 11.5%, 53.8%, and 34.6% of cases were strongly positive, positive, and weakly positive, respectively, for Ki-67 expression. About 42.3%, 42.3%, and 15.4% cases were strongly positive, positive, and weakly positive, respectively, for CD44 expression. Among 26 cases of SCC of the cervix 92.3% and 7.7% were positive and ambiguous respectively. About 73.1% and 26.9% of cases were strongly positive and positive, respectively, for Ki-67 expression. 65.4%, 30.8%, and 3.8% of cases were strongly positive, positive, and weakly positive, respectively, for CD44 expression. p16, Ki-67, and CD44 expression between the three groups were statistically significant. p16 expression versus FIGO stage including lymph node involvement and CD44 expression versus lymph node involvement in carcinoma cervix was statistically significant. Conclusion: Expression of p16, Ki-67, and CD44 increases as the lesion progress from normal to HSIL to carcinoma cervix. p16 and CD44 expression increase with lymph node involvement. P16 expression was maximum in Stage II than Stage III.

RESUMO

OBJECTIVES: The aim of the study is to determine whether a positive OncoE6 Anal Test result has statistically significant higher odds of being associated with high-grade squamous intraepithelial lesion (HSIL) and to calculate sensitivity and specificity of this test for predicting HSIL in adult men who have sex with men and are living with HIV (MSMLWH). MATERIALS AND METHODS: Men living with HIV 18 years or older having ≥atypical squamous cells of undetermined significance-grade anal cytology results were eligible to enroll in this cross-sectional study. Anal samples were collected just before the high-resolution anoscopy procedure. OncoE6 Anal Test results were compared with histology, the reference standard. Sensitivity, specificity, and odds ratio were calculated using HSIL as the threshold. RESULTS: Two hundred seventy-seven consented MSMLWH were enrolled between June 2017 and January 2022. Of these, 219 (79.1%) had biopsies obtained and histology performed; 81 of 219 participants (37%) had 1 or more biopsies with HSIL results while the remaining 138 of 219 (63%) had only low-grade squamous intraepithelial lesion or were negative for dysplasia. Anal samples from 7 participants (8.6%, 7/81) with HSIL and 3 (2.2%, 3/138) with low-grade squamous intraepithelial lesion had positive OncoE6 Anal Test results. Odds of having HSIL were 4.26 times higher among participants testing positive for HPV16/HPV18 E6 oncoprotein(s) (OR = 4.26, 95% CI = 1.07-16.95, p = .04). The OncoE6 Anal Test demonstrated excellent specificity, 97.83% (93.78-99.55), but poor sensitivity, 8.64% (3.55-17.0). CONCLUSIONS: In this highest-risk population for anal cancer, one could combine the OncoE6 Anal Test, having excellent specificity, with the anal Pap test, having higher sensitivity. Patients found having both an abnormal anal Pap and positive OncoE6 Anal Test result could be triaged for rapid scheduling of their high-resolution anoscopy.

RESUMO

PURPOSE: To determine whether treatment of anal high-grade squamous intraepithelial lesions (HSIL), vs active monitoring, is effective in reducing incidence of anal cancer in persons living with HIV, the US National Cancer Institute funded the Phase III ANal Cancer/HSIL Outcomes Research (ANCHOR) clinical trial. As no established patient-reported outcomes (PRO) tool exists for persons with anal HSIL, we sought to estimate the construct validity and responsiveness of the ANCHOR Health-Related Symptom Index (A-HRSI). METHODS: The construct validity phase enrolled ANCHOR participants who were within two weeks of randomization to complete A-HRSI and legacy PRO questionnaires at a single time point. The responsiveness phase enrolled a separate cohort of ANCHOR participants who were not yet randomized to complete A-HRSI at three time points: prior to randomization (T1), 14-70 (T2), and 71-112 (T3) days following randomization. RESULTS: Confirmatory factor analysis techniques established a three-factor model (i.e., physical symptoms, impact on physical functioning, impact on psychological functioning), with moderate evidence of convergent validity and strong evidence of discriminant validity in the construct validity phase (n = 303). We observed a significant moderate effect for changes in A-HRSI impact on physical functioning (standardized response mean = 0.52) and psychological symptoms (standardized response mean = 0.60) from T2 (n = 86) to T3 (n = 92), providing evidence of responsiveness. CONCLUSION: A-HRSI is a brief PRO index that captures health-related symptoms and impacts related to anal HSIL. This instrument may have broad applicability in other contexts assessing individuals with anal HSIL, which may ultimately help improve clinical care and assist providers and patients with medical decision-making.

RESUMO

Cervical cancer is the fourth most common female cancer worldwide and the fourth leading cause of cancer-related death in women. Nonetheless, it is also among the most successfully preventable and treatable types of cancer, provided it is early identified and properly managed. As such, the detection of pre-cancerous lesions is crucial. These lesions are detected in the squamous epithelium of the uterine cervix and are graded as low- or high-grade intraepithelial squamous lesions, known as LSIL and HSIL, respectively. Due to their complex nature, this classification can become very subjective. Therefore, the development of machine learning models, particularly directly on whole-slide images (WSI), can assist pathologists in this task. In this work, we propose a weakly-supervised methodology for grading cervical dysplasia, using different levels of training supervision, in an effort to gather a bigger dataset without the need of having all samples fully annotated. The framework comprises an epithelium segmentation step followed by a dysplasia classifier (non-neoplastic, LSIL, HSIL), making the slide assessment completely automatic, without the need for manual identification of epithelial areas. The proposed classification approach achieved a balanced accuracy of 71.07% and sensitivity of 72.18%, at the slide-level testing on 600 independent samples, which are publicly available upon reasonable request.

RESUMO

OBJECTIVE: The dilemma in treating cervical high-grade squamous intraepithelial lesion (HSIL) is how to achieve complete excision to minimize the risk of cervical cancer while sparing the anatomy of the cervix and its ability to function during pregnancy. The optimal management for positive margins after excisional treatment is still controversial. This study was conducted to determine the clinical and histologic predictors of residual/recurrent HSIL and assess the outcome of women with positive margin. MATERIALS AND METHODS: This retrospective cohort study included 386 women who had excisional treatment for HSIL during 1st January 2012 to 31st December 2015 in a university-affiliated hospital. RESULTS: Overall, 212 (54.9%) women had negative margins and 155 (40.2%) had positive margins. The cumulative rate of residual/recurrent HSIL at 2 and 5 years was 15.7% and 16.8% respectively in positive margins and 1.8% and 5.0% respectively in negative margins (p < 0.001). Of women who had residual/recurrent HSIL, significantly more women had positive margins compared to negative margins (74.1% vs 25.9%, p = 0.001). Positive margin was significantly associated with higher rate of subsequent abnormal cervical smear (48.2% vs 28.9%, p < 0.001), requiring further colposcopy (32.1% vs 14.4%, p < 0.001) and further treatment for SIL (7.5% vs 4.8%, p < 0.001) compared to negative margin. CONCLUSION: Most women (85%) with positive margin went without residual/recurrent HSIL, of which the option of close surveillance with cytology is reasonable. Repeat excision may be considered in selected women with positive margin, endocervical glandular involvement and those who are older or unable to comply with follow-up.

RESUMO

PURPOSE: Comparison of anal pre-cancer screening strategies in men who have sex with men (MSM). METHODS: MSM in the Multicenter AIDS Cohort Study underwent repeated anal cytology (aCyt), oncogenic human papillomavirus (oncHPV) testing. A subset received High-Resolution Anoscopy (HRA). We evaluated three screening strategies for their ability to predict anal histological High-Grade Squamous Intraepithelial lesion (HSIL): single aCyt, sequential aCyt, and oncHPV co-testing. Multivariable logistic regression models evaluated risk of HSIL among participants undergoing HRA within 5 years of screening. Sensitivity and specificity were estimated among participants with HRA, and results corrected for verification bias using weighted generalized estimating equations. RESULTS: There were 1426 MSM with aCyt screening (48% people with HIV [PWH]) and 428 that underwent HRA. Median age was 57 years, 14% of PWH had CD4< 350 cells/mm3. HSIL probability was higher in MSM with one (39%, p < 0.01) or two abnormal aCyt results (46%, p < 0.01), versus those with normal aCyt (23-24%). Among men with abnormal aCyt, men with oncHPV+ had significantly higher risk than those who were oncHPV- (47% vs. 16%, p < 0.01). Specificity was modest with single aCyt+ (50%) but increased with sequential aCyt+ (79%) or oncHPV+ (67%). Sensitivity was high with single oncHPV+ (88%), moderate with single aCyt+ (66%) and oncHPV+ co-testing (61%), and low with sequential aCyt+ (39%). After correcting for potential verification bias, specificity increased and sensitivity decreased, but inferences were similar. CONCLUSION: None of the screening strategies evaluated had both sufficient specificity and sensitivity to warrant routine widespread use.

RESUMO

OBJECTIVE: This study aimed to evaluate factors associated with anal high-grade intraepithelial lesions (HSIL) and anal carcinoma among young men who have sex with men (MSM) and transgender women (TW) with HIV in Atlanta, GA, to better inform screening guidelines and preventative measures. MATERIALS AND METHODS: Cross-sectional retrospective chart review was completed for cisgender MSM and TW with HIV aged 13-25 years at the Grady Ponce and Family Youth Clinic in Atlanta, GA, from 2009 to 2020. High-grade anal disease was defined as anal intraepithelial neoplasia (AIN) 2, 3, or anal carcinoma (AIN 2+). Associations between clinical and demographic factors with AIN 2+ were estimated using logistic regression. Adjusted odds ratios (aORs) and associated 90% CIs are reported. RESULTS: One hundred nine MSM and TW with HIV who underwent anoscopy were included. One hundred three participants received anal biopsies, and 62% had AIN 2+. Being incompletely or unvaccinated against human papillomavirus (HPV, 0-2 doses) relative to being fully vaccinated (3 doses; aOR = 5.85; 90% CI = 1.28-26.83; p = .06) and having ever received surgical treatment for anogenital HPV (aOR = 2.89; 90% CI = 1.10-7.65; p = .07) were associated with AIN 2+, controlling for age and CD4 T-cell count at time of biopsy. CONCLUSIONS: Our study found a high prevalence of anal HSIL among young MSM and TW with HIV. Those who had ever received surgical treatment for anogenital HPV and those who were incompletely or unvaccinated against HPV were more likely to have HSIL. Our data emphasize the urgent need to improve HPV vaccination efforts and to pursue larger surveillance studies of anal HSIL and carcinoma among young MSM and TW with HIV.

RESUMO

BACKGROUND: Targeted ablation of anal canal high-grade dysplasia results in high recurrence over time. Circumferential radiofrequency ablation might decrease recurrence. OBJECTIVE: This study aimed to determine the safety and efficacy of circumferential radiofrequency ablation for anal high-grade dysplasia. DESIGN: This was a dual-center, prospective trial of circumferential radiofrequency ablation with a 1-year follow-up with longer follow-up data abstracted from medical records of study patients returning after trial for surveillance. Ten participants from the identically conducted pilot circumferential radiofrequency ablation trial were included to improve sample size for longer-term analysis. SETTINGS: This study included 3 surgeons at 2 sites. PATIENTS: The study included 51 patients undergoing circumferential radiofrequency ablation for anal canal high-grade dysplasia. INTERVENTION: Circumferential radiofrequency ablation of anal canal high-grade dysplasia and targeted radiofrequency ablation of recurrence. MAIN OUTCOME MEASURES: The primary outcome measures were circumferential radiofrequency ablation efficacy and associated morbidity. RESULTS: Fifty-one participants underwent circumferential radiofrequency ablation but 48 participants returned for 1 or more postprocedure high-resolution anoscopy and were evaluable. The mean age of participants was 43 years, most were male (94%), 33% were living with HIV, and 58% had 3 or more high-grade dysplasias treated. Sixty percent had no recurrence, whereas 19% had 1 recurrence, 15% had 2 recurrences, and 6% had 3 recurrences. Most recurrences (66%) developed within the first 6 months. Kaplan-Meier probability of recurrence combining both series was 19% at 3 months, 30% at 6 months, and approximately 40% after 6 months out to 30 months. Most common morbidities were pain (85.4%) lasting for a median of 21 (range, 4-91) days and bleeding (91%) lasting for a median of 21 (range, 5-87) days. Of those with pain and bleeding, 65% and 85%, respectively, described it as mild. No patients developed fistulas, stricture, or incontinence. No serious adverse events related to circumferential radiofrequency ablation occurred. Having a previous recurrence was the only significant predictor of a subsequent recurrence (HR, 28.53) for recurrence at 9 months or before. LIMITATIONS: Enrollment ended prematurely, 10 participants from the pilot study were combined to increase the sample size, and longer-term follow-up was collected retrospectively were the limitations of this study. CONCLUSIONS: Circumferential radiofrequency ablation has improved efficacy over targeted ablation but with increased pain and bleeding. See Video Abstract at http://links.lww.com/DCR/B973 . ESTUDIO PROSPECTIVO BICNTRICO SOBRE LA ABLACIN POR RADIOFRECUENCIA CIRCUNFERENCIAL DE LESIONES ANALES INTRAEPITELIALES ESCAMOSAS DE ALTO GRADO DEMOSTRANDO MAYOR EFICACIA A LARGO PLAZO CON RELACIN A CONTROLES HISTRICOS DE ABLACIN DIRIGIDA: ANTECEDENTES:La ablación dirigida de la displasia de alto grado en el canal anal proporciona como resultados una alta recidiva a largo plazo. La ablación por radiofrecuencia circunferencial podría disminuir la reincidencia.OBJETIVO:Determinar la seguridad y eficacia de la ablación por radiofrecuencia circunferencial para la displasia anal de alto grado.DISEÑO:Estudio prospectivo bicéntrico de ablación por radiofrecuencia circunferencial con un seguimiento de 1 año, en base al monitoreo prolongado de datos, obtenidos de los registros medicos, de todos los pacientes incluidos en el estudio y que fueron controlados clinicamente. Diez participantes del estudio piloto de ablación por radiofrecuencia circunferencial realizada de manera idéntica, se combinaron para mejorar el análisis del tamaño de la muestra a largo plazo.PACIENTES:Se incluyeron 51 pacientes sometidos a la ablación por radiofrecuencia circunferencial de una lesion displásica de alto grado en el canal anal.AJUSTES:Tres cirujanos en 2 centros.INTERVENCIÓN:Ablación por radiofrecuencia circunferencial de la displasia de alto grado en el canal anal y ablación por radiofrecuencia dirigida de la recidiva.PRINCIPALES MEDIDAS DE RESULTADOS:Las medidas primarias fueron la eficacia de la ablación por radiofrecuencia circunferencial y la morbilidad asociada.RESULTADOS:Cincuenta y un participantes se sometieron a la ablación por radiofrecuencia circunferencial, de los cuales, 48 regresaron para ser evaluados con ≥1 anuscopias de alta resolución, después del procedimiento. La edad media de los participantes fue de 43 años, en su mayoría hombres (94%), el 33% eran portadores de VIH y el 58% tenía ≥3 lesiones displásicas de alto grado tratadas. El sesenta por ciento no tuvo recidiva, mientras que el 19%, 15% y 6% tuvieron 1, 2 o 3 recidivas. La mayoría de las recaídas (66%) se desarrollaron dentro de los primeros 6 meses. La probabilidad de recurrencia de Kaplan-Meier combinando ambas series fue del 19 % a los 3 meses, del 30 % a los 6 meses y aproximadamente del 40 % entre los 6 y 30 meses. Los indicadores de morbilidad más frecuentes fueron, el dolor (85,4%) con una mediana de duración de 21 días (rango, 4-91) y sangrado (91%) con una mediana de duración de 21días (rango, 5-87). Aquellos pacientes con dolor (65%) y sangrado (85%) respectivamente, los describieron como leves. Ningún paciente desarrolló fístula, estenosis o incontinencia. No se produjeron eventos adversos graves relacionados con la ablación por radiofrecuencia circunferencial. Tener una recurrencia previa fue el único factor predictivo importante de una recidiva ulterior (RH 28,53) en casos de recaída a los 9 meses o antes.LIMITACIONES:Como el registro finalizó prematuramente, se agregaron 10 participantes del estudio piloto para aumentar el tamaño de la muestra. El seguimiento a largo plazo fué recopilado retrospectivamente.CONCLUSIONES:La ablación por radiofrecuencia circunferencial ha mejorado la eficacia sobre la ablación dirigida pero con dolor y sangrado mas importantes.

RESUMO

OBJECTIVE: This study aimed to evaluate the influence of the excised canal length on relapse rates of cervical high-grade squamous intraepithelial lesion (HSIL) treated by loop electrosurgical excision procedure and to find a cut-off point, above which lower recurrence rates could be observed, with low probability of compromising future obstetric outcome, and the relationship with other individual factors related to HSIL recurrence. METHOD: This was a retrospective cohort study of 2,427 women diagnosed with cervical intraepithelial neoplasia CIN2+ who underwent cervical conization using the high-frequency loop electrosurgical excision procedure surgery technique, to analyze the role of endocervical canal length associated with individual factors in the recurrent disease after CIN2+ treatment and determine a cut-off point for the excised canal length needed to decrease the risk of disease relapse. RESULTS: In 2,427 cases, the relapse rate of HSIL treated was 12%. Compromised margins of conization, HIV+, and endocervical canal length were related directly to relapses ( p < .001). The cut-off point, by receiver operating characteristic curve, to calculate the endocervical canal length related to relapses was 1.25 cm of canal excised. Canal length of less than 1.25 cm increased the recurrence rate 2.5 times. Compromised margins and HIV+ increased recurrence rates by more than 5 times. CONCLUSION: Cervical HSIL recurrence was directly related to the endocervical canal length: excised canal length of 1.25 cm or more decreases recurrence rate; HIV and compromised margins increase the chance of recurrence by more than 5 times.

RESUMO

Objective: To investigate the natural regression and related factors of high-grade squamous intraepithelial lesion (HSIL) in the cervix of childbearing age women, and to evaluate the applicability of conservative management for future fertility needs. Methods: This study included 275 patients of reproductive age with fertility needs, who were diagnosed as HSIL by biopsy from April 30, 2015 to April 30, 2022, including 229 cases (83.3%) cervical intraepithelial neoplasia (CIN) Ⅱ and 46 cases (16.7%) CIN Ⅱ-Ⅲ. They were followed-up without immediate surgery in the First Affiliated Hospital of Nanjing Medical University. The median follow-up time was 12 months (range: 3-66 months). The regression, persistence and progression of lesions in patients with HSIL were analyzed during the follow-up period, the influencing factors related to regression and the time of regression were analyzed. Results: (1) Of the 275 HSIL patients, 213 cases (77.5%, 213/275) experienced regression of the lesion during the follow-up period. In 229 CIN Ⅱ patients, 180 cases (78.6%) regressed, 21 cases (9.2%) persisted, and 28 cases (12.2%) progressed. In 46 CIN Ⅱ-Ⅲ patients, 33 cases (71.7%) regressed, 12 cases (26.1%) persisted, and 1 case (2.2%) progressed to invasive squamous cell carcinoma stage Ⅰ a1. There was no significant difference in the regression rate between the two groups (χ2=1.03, P=0.309). (2) The average age at diagnosis, age <25 years old at diagnosis were independent influencing factor of HSIL regression in univariate analysis (all P<0.05). There was no significant difference between HSIL regression and pathological grading, the severity of screening results, human papillomavirus (HPV) genotype, colposcopy image characteristics, number of biopsies during follow-up and pregnancy experience (all P>0.05). (3) The median regression times for patients aged ≥25 years and <25 years at diagnosis were 15 and 12 months, respectively. Kaplan-Meier analysis showed that age ≥25 years at diagnosis significantly increased the median regression time compared to <25 years (χ2=6.02, P=0.014). Conclusions: For HSIL patients of childbearing age, conservative management without immediate surgical intervention is preferred if CINⅡ is fully evaluated through colposcopy examination. Age ≥25 years at diagnosis is a risk factor affecting the prognosis of HSIL patients.
