Conservative treatment of microinvasive squamous cell carcinoma of the cervix stage IA1: Defining conization height to an optimal oncological outcome. PLoS One 2021; 16:e0253998. [PMID: 34283862 PMCID: PMC8291715 DOI: 10.1371/journal.pone.0253998] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Accepted: 06/18/2021] [Indexed: 11/18/2022] Open
Abstract
OBJECTIVE This paper searches an ideal cone height for stage definition and safe treatment of cervical microinvasive squamous carcinoma stage IA1 (MIC IA1), avoiding excessive cervix resection, favoring a future pregnancy. METHODS A retrospective study was performed involving 562 women with MIC IA1, from 1985 to 2013, evaluating cone margin involvement, depth of stromal invasion, lymph vascular invasion, conization height, and residual uterine disease (RD). High-grade squamous lesions or worse detection was considered recurrence. Univariate and multivariate regression analyses were performed, including age, conization technique (CKC, cold-knife, or ETZ, excision of transformation zone), and pathological results. Conization height to provide negative margins and the risk of residual disease were analyzed. RESULTS Conization was indicated by biopsy CIN2/3 in 293 cases. Definitive treatments were hysterectomy (69.8%), CKC (20.5%), and ETZ (9.7%). Recurrence rate was 5.5%, more frequent in older women (p = 0.030), and less frequent in the hysterectomy group (p = 0.023). Age ≥40 years, ETZ and conization height are independent risk factors for margin involvement. For ages <40 years, 10 mm cone height was associated with 68.6% Negative Predictive Value (NPV) for positive margins, while for 15 mm and 25 mm, the NPV was 75.8% and 96.2%, respectively. With negative margins, the NPV for RD varied from 85.7-92.3% for up to 24 mm cone height and 100% from 25 mm. CONCLUSION Conization 10 mm height for women <40 years provided adequate staging for almost 70%, with 10% of RD and few recurrences. A personalized cone height and staging associated with conservative treatment are recommended.

Oncologic and obstetric outcomes after conization for adenocarcinoma in situ or stage IA1 cervical cancer. Sci Rep 2020; 10:19920. [PMID: 33199765 PMCID: PMC7669853 DOI: 10.1038/s41598-020-75512-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Accepted: 10/16/2020] [Indexed: 01/23/2023] Open
Abstract
This study aims to reveal the risk factors associated with recurrence or new-onset high-grade squamous intraepithelial lesions (HSILs) or more severe lesions (HSILs +) and analyze obstetrical outcomes in patients with adenocarcinoma in situ (AIS) or stage IA1 cervical cancer patients after conization. A retrospective cohort study was developed from January 1, 2002, and July 1, 2018, in a single center, where all patients with AIS or stage IA1 cervical cancer who accepted conization for primary surgery were reviewed and followed up until July 1, 2019, for the pathological findings of HSILs + and obstetric outcomes. Two hundred and seventeen patients were identified, including 114 cases of AIS, 76 cases of stage IA1 squamous cell carcinoma (SCC) and 27 cases of stage IA1 adenocarcinoma (ADC). A total of 88 (40.6%) patients had an intact uterus without radiotherapy. Five patients experienced HSIL+ recurrence. The cumulative 3-, 5- and 10-year incidence rates of HSILs + were 1.0%, 1.5% and 2.0%, respectively. No significant risk factors, including primary disease, margin status and hysterectomy, were associated with recurrence. Twenty (66.7%) of 30 patients who attempted pregnancy had 23 successful pregnancies, which result in 7 miscarriages, 16 live births and 5 preterm births. Age at conization was the only independent risk factor associated with pregnancy, live births and preterm births. In conclusion, conization is safe for young women with AIS, stage IA1 SCC and ADC who desire future fertility, and the associated HSIL recurrence rate is low. Increased age significantly lowered the conception or live birth rate.

Abstract
Pre-treatment survival prediction plays a key role in many diseases. We aimed to determine the prognostic value of pre-treatment Magnetic Resonance Imaging (MRI) based radiomic score for disease-free survival (DFS) in patients with early-stage (IB-IIA) cervical cancer. Methods: A total of 248 patients with early-stage cervical cancer underwent radical hysterectomy were included from two institutions between January 1, 2011 and December 31, 2017, whose MR imaging data, clinicopathological data and DFS data were collected. Patients data were randomly divided into the training cohort (n = 166) and the validation cohort (n=82). Radiomic features were extracted from the pre-treatment T2-weighted (T2w) and contrast-enhanced T1-weighted (CET1w) MR imagings for each patient. Least absolute shrinkage and selection operator (LASSO) regression and Cox proportional hazard model were applied to construct radiomic score (Rad-score). According to the cutoff of Rad-score, patients were divided into low- and high- risk groups. Pearson's correlation and Kaplan-Meier analysis were used to evaluate the association of Rad-score with DFS. A combined model incorporating Rad-score, lymph node metastasis (LNM) and lymphovascular space invasion (LVI) by multivariate Cox proportional hazard model was constructed to estimate DFS individually. Results: Higher Rad-scores were significantly associated with worse DFS in the training and validation cohorts (P<0.001 and P=0.011, respectively). The Rad-score demonstrated better prognostic performance in estimating DFS (C-index, 0.753; 95% CI: 0.696-0.805) than the clinicopathological features (C-index, 0.632; 95% CI: 0.567-0.700). However, the combined model showed no significant improvement (C-index, 0.714; 95%CI: 0.642-0.784). Conclusion: The results demonstrated that MRI-derived Rad-score can be used as a prognostic biomarker for patients with early-stage (IB-IIA) cervical cancer, which can facilitate clinical decision-making.

Abstract
OBJECTIVE The aim of this study was to evaluate the prognosis and recurrence of microinvasive squamous cervical (MIC) cancer stage IA1 in women treated conservatively or by hysterectomy, and followed-up to 20 years. METHODS It was studied in a cohort of 139 women with MIC, 41 definitively managed by conization and 98 by hysterectomy from January 1994 to December 2003 and followed-up until 2013. The definitive treatment, age, conization technique (loop electrosurgical excision procedure or cold knife conization), cone margin, residual disease in hysterectomy specimen, and the association with recurrence (intraepithelial cervical neoplasia grade 3/intraepithelial vaginal neoplasia grade 3 or worse, and microinvasive or worse) were analyzed. RESULTS There were 2.5 times more conservative treatment in younger women than older (>40 years), and high proportion of residual disease in hysterectomy specimens (67% of intraepithelial cervical neoplasia grade 3 or worse), more common if positive cone margin (74% vs 35%, P < 0.002). There were 2.3% (3/133) recurrences detected as microinvasive or worse, and 6% (8/133) recurrences detected as intraepithelial cervical neoplasia grade 3/intraepithelial vaginal neoplasia grade 3 or worse: 7.3% (3/41) in the conization group and 5.4% (5/92) in the hysterectomy group (P = 0.701). Almost all recurrences (88%, 7/8) were diagnosed until 36 months after treatment, and they were not associated with conization technique. There were no differences in risk of recurrence and overall disease-free survival time related to type of treatment. CONCLUSIONS This study demonstrates the good prognosis of MIC, regardless the treatment. When fertility is not a concern, hysterectomy should be considered as definitive treatment to avoid the risk of residual disease. Regular follow-up for a long period should be maintained.

Abstract
Background Accurate assessment of the depth of tumor invasion (DI) in microinvasive squamous cell carcinoma (MISCC) of the tongue is critical to prognosis. An arithmetic model is generated to determine a reliable method of measurement of DI and correlate this with the local recurrence. Material and Methods Tumor thickness (TT) and DI were measured in tissue sections of 14 cases of MISCC of the tongue, by manual ocular micrometer and digital image analysis at four reference points (A, B, C, and D). The comparison of TT and DI with relevant clinicopathologic parameters was assessed using Mann Whitney U test. Reliability of these methods and the values obtained were compared and correlated with the recurrence of tumors by Wilcoxon Signed Ranks Test. 3D reconstruction of the lesion was done on a Cartesian coordinate system. X face was on the YZ plane and Z face was on the XY plane of the coordinate system. Results Computer generated 3D model of oral mucosa in four cases that recurred showed increased DI in the Z coordinate compared to the XY coordinate. The median DI measurements between XY and Z coordinates in these cases showed no significant difference (Wilcoxon Signed Ranks Test, p = 0.068). Conclusions The assessment of DI in 3 dimensions is critical for accurate assessment of MISCC and precise DI allows complete removal of tumor. Key words:Depth of invasion, tumor thickness, microinvasive squamous cell carcinoma, tongue squamous cell carcinoma.

Abstract
ObjectiveTo define a subset of patients with early-stage cervical cancer at low risk for parametrial invasion through pathologic parameters of loop electrosurgical excision procedure (LEEP).Materials and MethodsA retrospective analysis of data from 131 patients who underwent LEEP before radical hysterectomy or radical trachelectomy for stage IA2 to IB1 cervical cancer was performed. Subgroup analysis was performed to define a group of patients at the lowest risk for parametrial invasion based on LEEP findings.ResultsOverall, 7 (5.3%) of 131 patients showed parametrial involvement, all of whom had residual tumors in hysterectomy specimens. Risk factors for residual disease included a tumor width greater than 30 mm and a positive endocervical or deep resection margin. A subgroup analysis demonstrated that LEEP parameters, including a depth of invasion of 5 mm or less and a negative endocervical resection margin, were able to define the subgroup of patients at low risk for parametrial invasion. In 24 patients (18.3%) who met these criteria, there was no evidence of parametrial spread as well as nodal metastasis.ConclusionA subgroup of patients with early-stage cervical cancer selected by the 2 LEEP variables, depth of invasion of 5 mm or less and a negative endocervical resection margin, demonstrated no risk for parametrial invasion.

Abstract
OBJECTIVE The purpose of this study was to evaluate colposcopic sensitivity in the diagnosis of microinvasive squamous carcinoma of the cervix. STUDY DESIGN We conducted a cross-sectional study in 151 patients from 1991-2008. The colposcopic findings of microinvasion suspicion were described by the International Federation for Cervical Pathology and Colposcopy in 2003. RESULTS There has been colposcopic suspicion of invasion in 35 patients, which represents a sensitivity of 23%. The major colposcopic findings that were observed in the transformation zone included acetowhite epithelium in 21% (32/151 patients), coarse punctuation in 19% (29/151 patients), coarse mosaic in 17% (26/151 patients), and atypical vessels in 3.9% (6/151 patients). Suspicion of microinvasion was found in 14.5% of unsatisfactory colposcopy and in 8.6% of satisfactory colposcopy. CONCLUSION The sensitivity of colposcopy in the diagnosis of microinvasive carcinoma of the cervix was low. Colposcopy plays an important role in directing the biopsy to the most suspicious area. The definitive diagnosis of microinvasive squamous carcinoma is established only by histologic study.

Abstract
Objective:This study was performed to evaluate the efficacy and feasibility of electrosurgical conization and cold coagulation as definitive treatments for patients with International Federation of Gynecology and Obstetrics stage IA1 squamous cell carcinoma of the cervix and a resection margin free from (micro)invasive carcinoma after conization.Methods:Patients with stage IA1 cervical squamous cell carcinoma without lymphovascular space invasion who had been treated by electrosurgical conization and cold coagulation and who wanted to preserve fertility (or only undertake conservative treatment) were followed up without further surgical intervention. Patients with invasive or microinvasive carcinoma at resection margins or positive endocervical resection margins were excluded from the study. Cervicovaginal smears and colposcopic examination were performed at regular intervals. Disease recurrence was defined as a histologic diagnosis of cervical intraepithelial neoplasia 2 or higher-grade lesions.Results:A total of 85 patients enrolled were deemed eligible to be involved in the study. The median follow-up period was 81.0 months (range, 13-127 months). Nineteen of the 85 patients had exocervical resection margins. There was one case of recurrence, which was node-positive invasive cancer recurrence (1.2%, 1/85), in patients with negative resection margins.Conclusions:These results suggest that electrosurgical conization with cold coagulation is a feasible treatment and could be used as a definitive therapy for patients with stage IA1 cervical squamous cell carcinoma without lymphovascular space invasion. In addition, patients having cervical intraepithelial neoplasias 2 and 3 at exocervical resection margins could be followed up carefully without further treatment after conization and cold coagulation.

Abstract
Objective:To assess the rate, the cumulative proportion, and the predictors of cervical intraepithelial neoplasia grades 2-3 (CIN 2-3) and invasive disease during the follow-up of patients conservatively treated for microinvasive (stage Ia1-2) squamous cell carcinoma (MIC) of the uterine cervix.Methods:Two hundred thirty women (median age, 37 years; range, 20-69 years) conservatively treated for MIC were followed up for 10 years and analyzed for cumulative proportion of CIN 2-3/invasive disease. The multivariate survival analysis was used to assess the clinicopathological features predicting the development of CIN 2-3/SCC.Results:Of the 230 patients primarily treated by cone, 76 (33%) underwent hysterectomy as the immediate retreatment, and 13 had a residual disease. The remaining 154 women were subjected to posttreatment follow-up. The depth of stromal invasion was strongly associated with the prevalence of positive lymph nodes and lymphovascular space invasion (LVSI). The detection rate of CIN 2-3/SCC was stable at the first 2 visits (6.5% and 6.9%) and dropped thereafter. The cumulative proportion of patients whose conditions were diagnosed as CIN 2-3/carcinoma was 0.07, 0.09, 0.15, and 0.19 at 6, 12, 36, and 120 months, respectively. In multivariate survival analysis, involvement of 4 quadrants (odds ratio [OR], 5.8), LVSI (OR, 4.5), and cone margin involvement (OR, 5.6) were significant independent predictors of CIN 2-3/SCC after treatment. The upper age tertile (42-69 years) was an independent protective factor (OR, 0.3; 95% confidence interval, 0.1-0.9).Conclusions:A close, long-term surveillance should be scheduled for the MIC patients conservatively treated. Cone margin involvement, LVSI, and the number of quadrants involved on colposcopy are independent risk factors for disease persistence and/or progression to SCC.

Abstract
OBJECTIVE The purpose of this study was to determine whether lymph-vascular space invasion (LVSI) that is discovered in cervical biopsy and excision specimens is associated with LVSI in the hysterectomy specimen of patients with cervical cancer. STUDY DESIGN A retrospective pathologic review to determine the presence of LVSI in cervical biopsy specimens, cold-knife cone biopsy (CKC biopsy), and loop electrical excision procedure (LEEP) specimens that contained cervical cancer was performed if subsequent hysterectomy results were available for review. Data were analyzed with chi-square analysis testing. RESULTS One hundred six patients were identified. The negative predictive value of the biopsy is lower at 0.45 than either the CKC biopsy (0.83) or LEEP (0.57); however, the positive predictive value (0.83) is higher than either CKC biopsy (0.50) or LEEP (0.75). LVSI, when present in cervical biopsy (odds ratio, 4.13; 95% CI, 0.414-98.446), CKC biopsy (odds ratio, 4.8; 95% CI, 0.542-46.280), and LEEP (odds ratio, 4.0; 95% CI, 0.439-43.793) specimens, is associated with a statistically insignificant increased risk of LVSI in the hysterectomy specimen. CONCLUSION Cervical biopsy and excision specimens lack sufficient negative predictive value for the detection of LVSI in the hysterectomy specimen.

Abstract
Background Nanog, nucleostemin (NS) and musashi1 (Msi1) are proteins that are highly expressed in undifferentiated embryonic stem (ES) cells and have been shown to be essential in maintaining the pluripotency and regulating the proliferation and asymmetric division of ES cells and several nervous system tumor cells. The roles of Nanog, NS and Msi1 in development and progression of cervical carcinoma have, until now, not been well documented. Methods In this study, expression of Nanog, NS and Msi1 was detected by immunohistochemistry analysis in 235 patients with various degrees of cervical epithelial lesions, including 49 with normal cervical epithelia, 31 with mild dysplasia (CIN I), 77 with moderate-severe dysplasia (CIN II-III) and 78 with squamous cervical carcinomas (SCCs). Associations with various clinical pathological prognostic variables were analyzed in 50 early-stage SCC patients. Results Nanog, NS and Msi1 expression levels were significantly higher in SCC patients compared with CIN patients, and were higher in CIN patients compared with those with normal cervical epithelia. Nanog expression levels showed significantly differences according to different tumor sizes (P < 0.05), whereas there were no differences in NS and Msi1 expression levels according to different clinical pathological parameters. Conclusion Our findings indicate that Nanog, NS and Msi1 may be involved in carcinogenesis of the cervix and progression of cervical carcinoma.

Abstract
Hairy and Enhancer-of-split homologues 1 and 5 (Hes1 and Hes5) are the basic helix-loop-helix transcriptional factors that negatively regulate the cell differentiation during embryogenesis. It has been reported that they may be involved in carcinogenesis in some tumors. The roles of Hes1 and Hes5 in development and progression of cervical carcinoma are not well documented todate. In the study, the expression of Hes1 and Hes5 were detected by immunohistochemistry in 295 cases with various degrees of cervical epithelial lesions, including 78 normal cervical epithelia, 31 mild dysplasia (CIN I), 77 moderate-severe dysplasia (CIN II–III), and 109 squamous cervical carcinomas (SCCs), and their association with various clinical pathologic prognostic variables were analyzed in 73 early-stage SCC patients who underwent surgery. Hes1 and Hes5 expression were found to be significantly higher in SCC compared with CIN as well as higher in CIN than normal cervical epithelia, and positively correlated with various prognostic factors in early-stage cervical carcinoma. Our findings suggest that Hes1 and Hes5 may be involved in carcinogenesis of the cervix and progression of cervical carcinoma. Hes1 and Hes5 overexpression are probably variables to predict poor prognosis of the patients with early-stage cervical carcinoma

Several authors have proposed the use of a less aggressive surgery (i.e. conization, trachelectomy plus laparoscopic lymphadenectomy, modified or type 2 radical hysterectomy) for patients affected by early stages invasive cervical carcinoma. Tumor size and pelvic nodal status are parameters that must be evaluated to better select a patient's population suitable of a less aggressive surgery, with the aim of sparing morbidity without jeopardizing cancer cure.
