Wang J, Wang C, Su T. Risk factors for residual lesions after total hysterectomy in patients with high-grade cervical intraepithelial neoplasia. BMC Womens Health 2024; 24:369. [PMID: 38915002 PMCID: PMC11194937 DOI: 10.1186/s12905-024-03212-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Accepted: 06/18/2024] [Indexed: 06/26/2024] Open
Abstract
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.

[PMID: 37869677 PMCID: PMC10587556 DOI: 10.3389/fmicb.2023.1266254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 09/22/2023] [Indexed: 10/24/2023] Open
Abstract
Introduction Persistent human papillomavirus infection is an important factor in the development of cervical cancer, which is usually a long process evolving from the development of squamous intraepithelial lesions (SIL), also referred to as cervical intraepithelial neoplasia (CIN). Local treatment of advanced squamous intraepithelial lesions, also regarded as High-Grade Squamous Intraepithelial Lesion, may be effective in preventing cancer. Objective To promptly identify high-risk patients with a tendency to recurrence. Methods We retrospectively analyzed the clinical data of 300 patients with high-grade squamous intraepithelial lesions of the cervix admitted to the Second Affiliated Hospital of Dalian Medical University from 2019 to 2020 to investigate the relationship between recurrence of cervical lesions and postoperative regression of HPV infection, as well as other related risk factors. Results We found that the HPV-negative rates were 81.81, 85.71, and 90.91% at 6, 12, and 24 months, respectively, and the average lesion recurrence rate was 8.16%, with a median time to recurrence of 14 months in patients undergoing CKC for HSIL. The risk of cervical squamous intraepithelial lesions was highest in patients with HPV16. Patients over 61 years of age had the lowest postoperative HPV-negative rate. The conversion rate was significantly lower in patients with multiple HPV genotypes than in those with single HPV infection (p < 0.05). The probability of recurrence was higher in patients with the same HPV infection genotype before and after surgery than in patients with different infection genotypes before and after surgery (p < 0.05). Conclusion Combined with the literature review, we believe that patients aged ≥50 years, with ≥3 pregnancies and births, a history of smoking, and consistent genotypes of preoperative and postoperative HPV infection in cervical conization have more HPV re-infection or persistent infection, and that these factors may be high-risk factors for lesion recurrence. For patients with possible potential high-risk factors, we need to carry out individualized follow-up and focused management, take timely and effective management measures, optimize the treatment plan, reduce the recurrence rate, prevent HSIL and cervical cancer, improve the quality of patient's survival, and improve the prognosis.

Extensive lesions and a positive cone margin are strong predictors of residual disease in subsequent hysterectomy following conization for squamous intraepithelial lesion grade 2 or 3 study design. BMC Womens Health 2023; 23:454. [PMID: 37641051 PMCID: PMC10464471 DOI: 10.1186/s12905-023-02568-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Accepted: 07/24/2023] [Indexed: 08/31/2023] Open
Abstract
BACKGROUND This study aimed to determine the predictive factors for post-conization of residual disease in subsequent hysterectomy for cervical intraepithelial neoplasia grade 2 or 3. METHODS This retrospective study included 267 patients with histologically confirmed cervical intraepithelial neoplasia grade 2 or 3 who underwent hysterectomy within 7 months after conization. Clinical data (e.g., age, menopausal status, gravidity, parity, type of transformation zone, conization method) as well as pathological data pertaining to conization and hysterectomy were collected from medical records. A logistic regression model was used to analyze the relationship between the variables and risk of residual lesions in hysterectomy samples. RESULTS Overall, 70 (26.2%) patients had residual lesions in their hysterectomy specimens. Univariate analyses revealed that age ≥ 50 years (p=0.019), endocervical gland involvement(p=0.013), positive margin(p < 0.001), and involvement of 3-4 quadrants(p < 0.001) were risk factors for residual lesions. Conversely, postmenopausal status, gravidity ≥ 3, parity ≥ 2, loop electrosurgical excision procedure, and type III transformation zone were not risk factors for residual lesions. A positive margin(p < 0.001) and multiple-quadrant involvement(p < 0.001) were identified as independent risk factors for residual lesions on multivariate analysis. CONCLUSIONS Multiple-quadrant involvement and a positive cone margin were reliable predictive factors for residual disease. Total hysterectomy or repeated cervical conization should be considered for patients with these two risk factors. The identification of high-risk patients with extensive lesions by colposcopic examination before conization is indispensable, as it will enable surgeons to perform conization with consideration of risk factors and possibly improve the approach used for the excisional procedure. For high-risk patients, colposcope-guided cold-knife conization is preferred when resources permit.

Abstract
OBJECTIVE Pathological involvement of cervical conization margins is a risk factor for recurrence, although management of these patients is controversial. We aimed to define risk factors for positive margins and compare recurrence following additional surgical intervention compared to conservative management. METHODS A retrospective study of all conizations at our center between 2010 and 2019. Univariate analysis identified characteristics associated with positive margins. Women were stratified by mode of management comparing three groups (surveillance, repeat conization or hysterectomy) then two groups (surveillance vs. additional surgery). Kaplan Meyer survival curves compared cumulative recurrence stratified by mode of management. Pathological results of subsequent surgical procedures were examined for residual disease. RESULTS Of 448 conizations performed, 131 (29.2%) had positive margins which were associated with menopause, high-grade cytology and endocervical gland involvement. Women who underwent surveillance (n = 45) were more likely to be nulliparous, with low-grade histology and less endocervical gland involvement. Women who underwent hysterectomy (n = 61) were more likely to be postmenopausal and parous. Recurrence did not differ significantly in the three-group (p = 0.073) or two-group model (6.4% vs. 7.1% p = 0.869). Kaplan Meyer survival curves depicting cumulative recurrence did not differ significantly in either model (log rank test p = 0.642 for the three-group model, and p = 0.868 for the two-group model). Residual disease was found in 51.6% of hysterectomy specimens and 52.6% of repeat conizations. CONCLUSION Surveillance is non-inferior to additional surgery in cases with positive conization margins and constitutes a valid option specifically for younger women at risk of future obstetric complications and those susceptible post-hysterectomy complications.

Abstract
To explore the optimal way to manage patients with high-grade squamous intraepithelial lesion (HSIL) and positive margin by identifying the risk factors for its recurrence and residue.A retrospective study was conducted on 267 cases of a pathologically confirmed HSIL with positive margin following conization by loop electrosurgical excisional procedure (LEEP) between January 2010 and December 2015. One hundred two cases were selected for regular follow-up every 6 months, and 165 cases were selected for a second surgery (repeat cervical conization or hysterectomy) within 3 months of initial LEEP. We analyzed the association between recurrent or residual diseases and these factors: age, menopausal status, ThinPrep cytologic test (TCT) results, high-risk human papillomavirus (HR-HPV) infection, pathological grades of the margin, number of involved margins, and glandular involvement.The recurrence rate among 102 cases who underwent follow-up was 17.6% (18/102). The factors: atypical squamous cells of undetermined significance cannot exclude HSIL (ASC-H) or higher lesions in the pre-LEEP TCT (P = .038), persistent HR-HPV infection at the 6th month post-LEEP (P = .03), HSIL-positive margin (P = .003), and multifocal-involved margin (P = .002) were significantly associated with recurrent disease, while age, menopause, and pre-LEEP HR-HPV infection were not associated with recurrent disease (P > .05). The residual rate among 165 patients who underwent a second surgery was 45.5% (75/165), of which 15 cases were residual cervical cancer. The factors: menopause (P = .02), ≥ASC-H in pre-LEEP TCT (P = .04), pre-LEEP HR-HPV infection (P = .04), ≥HSIL-positive margin (P < .001), and multifocal-involved margin (P < .001) significantly increased the risk of residual disease. No correlation existed between residual disease and age or glandular involvement (P > .05).For patients with a positive margin after LEEP, regular follow-up or second surgery should be selected according to fertility requirement and pathological characteristics of the positive margin, as well as TCT and HR-HPV infection condition.

Abstract
Objective The Japan Society of Obstetrics and Gynecology conducted a retrospective multi-institutional survey of patients who underwent cervical conization in Japan. This study aimed to determine the predictive factors for positive surgical margins in cervical intraepithelial neoplasia grade 3 (CIN 3) patients after therapeutic cervical conization and those for positive margins in patients who did not experience recurrence and did not undergo additional treatment. Methods In 2009 and 2013, 14,832 patients underwent cervical conization at 205 institutions in Japan. Of these, 8856 patients who underwent therapeutic conization fulfilled the inclusion criteria. Their histologic findings and clinical outcomes were evaluated based on standard statistical procedures and clinical and demographic characteristics. Results Negative and positive margins were observed in 7,585 and 1,271 (14.4%) patients, respectively. The predictors of positive margins were menopausal status (p<0.001), loop electrosurgical excision procedure (p<0.001), and Shimodaira-Taniguchi (S-T) conization (p<0.001). Of 1,271 patients with positive margins, 1,060 underwent no additional treatment; among those 1,060 patients, 129 (12.2%) experienced recurrence. The predictors of positive margins in patients who did not undergo additional treatment and did not experience recurrence were age, parity, gravidity, S-T conization, and laser scalpel conization. Conclusion Menopausal status and treatment procedures were associated with positive margins after therapeutic conization of CIN 3. It is important to understand the characteristics of treatment procedures and select an appropriate procedure for each case. For elderly or menopausal patients with positive margins, immediate additional treatment is recommended.

Abstract
BACKGROUND 20-25% of women with high-grade cervical intraepithelial neoplasias (HSIL) have residual lesions after conization. The state of the margin is generally considered to be a risk factor for recurrence or persistent lesions. Predictors of positive margins and residual lesions need to be identified. A design for postoperative management and avoidance of overtreatment needs to be provided, especially for women of child-bearing age. METHODS This study was a retrospective analysis of 1309 women of child-bearing age with HSIL, who underwent cold knife conization (CKC). Age, gravidity, parity, human papillomavirus (HPV) species, cytology, transformation zone type, results of endocervical curettage (ECC), quadrant involvement, glandular involvement, and Cervical Intraepithelial Neoplasia (CIN) grade were analyzed. Among those with positive margins, 245 patients underwent secondary surgery within three months, including CKC, a loop electrosurgical excision procedure, and total hysterectomy. Risk factors for positive margins and residual lesions were assessed. RESULTS There was no significant difference in age, gravidity, parity, glandular involvement, and CIN grade between the two groups (P > 0.3). There was a significant difference in HPV species, cytology, ECC results, and quadrant involvement (P < 0.002). Multivariate analysis showed a major cytology abnormality, high-risk HPV infection, type III transformation zone, positive ECC result, and multiple quadrant involvement were independent risk factors for positive margins and residual lesions (P < 0.02). Age > 35 years was also a risk factor for residual lesions (P < 0.03). CONCLUSION High-risk women should be treated appropriately considering fertility. Patients with positive margins should be managed uniquely. Surgery for women without fertility may be appropriate. Close follow-up is necessary for women who have fertility requirements or are unwilling to undergo subsequent surgery if they have no risk factors, especially women < 35 years.

Int J Gen Med 2020; 13:1067-1074. [PMID: 33204141 PMCID: PMC7667014 DOI: 10.2147/ijgm.s280576] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Accepted: 10/20/2020] [Indexed: 12/03/2022] Open
Abstract
Background Post-menopausal patients with cervical intraepithelial neoplasia (CIN) have a high rate of residual or recurrent lesions after treatment, and their risk for cervical cancer later in life is higher than the general population. Hence, management for this specific group of post-menopausal patients needs more attention. Objective The study aimed to identify risk factors associated with the presence of residual disease in hysterectomy specimens in post-menopausal patients with cervical intraepithelial neoplasia grade 3 (CIN 3). Methods This study was a retrospective analysis of data from post-menopausal women who had undergone hysterectomy following conization for CIN 3 from 2012 to 2018 at Fujian Maternity and Child Health Hospital. Factors extracted from the database included age, parity, Thinprep cytology results, human papillomavirus (HPV) genotype, biopsy results, pre-cone endocervical curettage (ECC) results, conization method, operating surgeon, cone dimension, margin status and glandular involvement. Univariate and multivariate analyses were performed to identify risk factors associated with residual disease in hysterectomy specimens. Results Analysis of data from 129 women was performed. The proportion of residual disease was 43.41% overall. A higher grade according to colposcopy biopsy, abnormal pre-cone ECC results, the cone method (LEEP vs CKC), a cone volume >1.57 cm3, and positive margins in conization specimens were found to be significantly associated with residual lesions on univariable analysis. After multivariate analysis, only an abnormal pre-cone ECC result (odds ratio 3.99; 95% confidence interval (CI) 1.41–11.33; p = 0.009) remained significant. Conclusion The rate of residual lesions in uterine specimens was high regardless of the cone margin status in post-menopausal women with CIN 3. Risk-based strategies are needed to identify patients who have abnormal pre-cone ECC results, and definitive treatment with hysterectomy should be considered in post-menopausal patients with an elevated risk for residual lesions.
