Abstract
OBJECTIVE The main outcome of this study was the evaluation of clinical characteristics, comorbidities, and therapeutic approaches in patients with vulvar lichen sclerosus (VLS) aged from childhood to perimenopause. Secondly, it was intended to compare these characteristics according to the menarchal status. METHODS Patients less than 45 years of age with a diagnosis of VLS from January 2002 to June 2022 in 10 referral centers were included in this retrospective longitudinal study. The univariate analysis compared the dependent variables according to menarchal status. RESULTS One hundred eighty-six patients met the inclusion criteria. At diagnosis, between 25% and 40% of premenarchal patients reported signs related to subepithelial hemorrhage. A significantly greater presence of bleeding (p < .005), easy bruising (p = .028), fissures (p = .008), petechiae/splinter hemorrhages (p < .001), and bleeding/blistering or open sores (p = .011) was observed in premenarchal patients with respect to the postmenarchal group. The perineum (p = .013) and the perianal region (p < .001) were significantly more involved in the premenarchal group. Topical calcineurin inhibitors were more used in the premenarchal population (p = .004), whereas vitamin E oil and moisturizers were more used in the postmenarchal population (p = .047). CONCLUSIONS Vulvar lichen sclerosus is a chronic condition that can cause vulvar changes that result in severe morbidity and affects sexual function and quality of life, even before menopause. Vulvar lichen sclerosus continues to be misdiagnosed in this population. This may lead to an average delay from symptom onset to diagnosis. Evaluating clinical manifestations of VLS in premenarchal and postmenarchal age allowed us to find different clinical characteristics between the 2 periods suggestive of the diagnosis.

Atypical Endometrial Hyperplasia and Concurrent Cancer: A Comprehensive Overview on a Challenging Clinical Condition. Cancers (Basel) 2024; 16:914. [PMID: 38473276 DOI: 10.3390/cancers16050914] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 02/18/2024] [Accepted: 02/21/2024] [Indexed: 03/14/2024] Open
Abstract
The present review regarding atypical endometrial hyperplasia (AEH) focused on the main debated factors regarding this challenging clinical condition: (i) predictive variables of occult endometrial cancer (EC); (ii) the rate of EC underestimation according to different endometrial sampling methods; and (iii) the appropriateness of lymph node status assessment. When cancer is detected, approximately 90% of cases include low-risk EC, although intermediate/high-risk cases have been found in 10-13% of women with cancer. Older age, diabetes, high BMI, and increased endometrial thickness are the most recurrent factors in women with EC. However, the predictive power of these independent variables measured on internal validation sets showed disappointing results. Relative to endometrial sampling methods, hysteroscopic endometrial resection (Hys-res) provided the lowest EC underestimation, ranging between 6 and 11%. Further studies, including larger sample sizes of women undergoing Hys-res, are needed to confirm these findings. These data are urgently needed, especially for female candidates for conservative treatment. Finally, the evaluation of lymph node status measured on 660 of over 20,000 women showed a lymph node positivity of 2.3%. Although there has been an increase in the use of this procedure in AEH in recent years, the present data cannot recommend this option in AEH based on a cost/risk/benefit ratio.

Raf kinase inhibitor protein expression in smooth muscle tumours of the uterus: a diagnostic marker for leiomyosarcoma? Reprod Biomed Online 2024; 48:103816. [PMID: 38608337 DOI: 10.1016/j.rbmo.2024.103816] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 01/04/2024] [Accepted: 01/08/2024] [Indexed: 04/14/2024]
Abstract
RESEARCH QUESTION What is the expression pattern of Raf kinase inhibitory protein (RKIP) in different subtypes of leiomyoma (usual type, cellular, apoplectic or haemorrhagic leiomyoma, leiomyoma with bizarre nuclei and lipoleiomyoma) and leiomyosarcoma specimens, and what is its biological role in leiomyosarcoma cells? DESIGN Leiomyoma and leiomyosarcoma specimens underwent immunohistochemistry staining. Leiomyosarcoma SK-LMS-1 cell line was RKIP knocked down and RKIP overexpressed, and cell viability, wound healing migration and clonogenicity assays were carried out. RESULTS A higher immunohistochemical expression of RKIP was observed in bizarre leiomyomas, than in usual-type leiomyomas. Decreased expression was also found in cellular leiomyoma, with generally absent staining in leiomyosarcomas. Upon RKIP expression manipulation in SK-LMS-1 cell line, no major differences were observed in cell viability and migration capacity over time. RKIP knockout, however, resulted in a significant increase in the cell's ability to form colonies (P = 0.011). CONCLUSION RKIP distinct expression pattern among leiomyoma histotype and leiomyosarcoma, and its effect on leiomyosarcoma cells on colony formation, encourages further studies of RKIP in uterine smooth muscle disorders.

Concurrent Endometrial Cancer in Women with Atypical Endometrial Hyperplasia: What Is the Predictive Value of Patient Characteristics? Cancers (Basel) 2023; 16:172. [PMID: 38201599 PMCID: PMC10778118 DOI: 10.3390/cancers16010172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 12/20/2023] [Accepted: 12/27/2023] [Indexed: 01/12/2024] Open
Abstract
BACKGROUND The rate of concurrent endometrial cancer (EC) in atypical endometrial hyperplasia (AEH) can be as high as 40%. Some patient characteristics showed associations with this occurrence. However, their real predictive power with related validation has yet to be discovered. The present study aimed to assess the performance of various models based on patient characteristics in predicting EC in women with AEH. METHODS This is a retrospective multi-institutional study including women with AEH undergoing definitive surgery. The women were divided according to the final histology (EC vs. no-EC). The available cases were divided into a training and validation set. Using k-fold cross-validation, we built many predictive models, including regressions and artificial neural networks (ANN). RESULTS A total of 193/629 women (30.7%) showed EC at hysterectomy. A total of 26/193 (13.4%) women showed high-risk EC. Regression and ANN models showed a prediction performance with a mean area under the curve of 0.65 and 0.75 on the validation set, respectively. Among the best prediction models, the most recurrent patient characteristics were age, body mass index, Lynch syndrome, diabetes, and previous breast cancer. None of these independent variables showed associations with high-risk diseases in women with EC. CONCLUSIONS Patient characteristics did not show satisfactory performance in predicting EC in AEH. Risk stratification in AEH based mainly on patient characteristics may be clinically unsuitable.

A survey on the current practice of indicating an elective cesarean after a previous myomectomy. Ann Med 2023; 55:2197292. [PMID: 37043241 PMCID: PMC10101679 DOI: 10.1080/07853890.2023.2197292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 04/13/2023] Open
Abstract
OBJECTIVE The objective of this study was to evaluate the attitude of obstetricians/gynecologists toward indicating an elective cesarean delivery in pregnant patients with a previous myomectomy. MATERIALS AND METHODS Web-based multiple-choice questions survey evaluating the attitude to indicate a cesarean with a composite summated score (range 56-280) from a 56-item Likert scale: score 56-112: weak attitude, 113-168: moderate, 169-224: strong, and 225-280: very strong. The reliability of the score (internal consistency) was evaluated with Cronbach's alpha coefficient. The association between the score and participants' characteristics was determined with a bivariate analysis followed by linear regression analysis. The "global importance" of each risk factor was defined as the prevalence of the answers: "moderately important", "very important", and "extremely important" on the Likert scale. Factors with a "global importance" >75% were considered "crucial" in influencing the choice to indicate a cesarean. RESULTS One-hundred-twenty obstetricians/gynecologists responded (response rate 70.6%). The mean ± SD composite summated score was 137 ± 31; 30 (25.0%) participants presented a "weak attitude to cesarean", 68 (56.7%) a "moderate attitude", 22 (18.3%) a "strong attitude", and none a "very strong attitude". The Cronbach's alpha was 0.934 (high internal consistency). A self-reported number of myomectomies performed per year >50 was associated with a lower score (-25 points, 95% CI -50 to -1, p = 0.04). Eight criteria resulted "crucial" in indicating a cesarean: opening of the endometrial cavity, monopolar electrosurgery, time surgery-pregnancy <6 months, 2+ previous myomectomies, hematoma formation in the surgical wound, 3+ removed fibroids, and a FIGO4 or FIGO3 removed fibroid. CONCLUSIONS Obstetricians/gynecologists are cautious to indicate a cesarean in pregnant patients with a previous myomectomy, except for cases at hypothetic high-risk for uterine rupture, mainly supported by weak evidence. Information to patients and among clinicians is crucial to avoid inappropriate cesarean indications.KEY MESSAGESObstetricians/gynecologists are cautious to indicate a cesarean in pregnant patients with a previous myomectomy.Information to patients and among clinicians is crucial to avoid inappropriate cesarean indications in pregnant patients with a previous myomectomy.

Homozygous C677T Methylenetetrahydrofolate Reductase (MTHFR) Polymorphism as a Risk Factor for Endometriosis: A Retrospective Case-Control Study. Int J Mol Sci 2023; 24:15404. [PMID: 37895084 PMCID: PMC10607746 DOI: 10.3390/ijms242015404] [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: 09/05/2023] [Revised: 10/10/2023] [Accepted: 10/13/2023] [Indexed: 10/29/2023] Open
Abstract
This study was conducted to evaluate the role of methylenetetrahydrofolate reductase (MTHFR) C677T homozygous polymorphism as a risk factor for endometriosis. A retrospective case-control study was conducted from January 2020 to December 2022 on all patients attending the gynecological outpatient clinic of our institution who had performed an MTHFR polymorphisms test. Patients with endometriosis were considered cases, while those without endometriosis were considered controls. The presence of an MTHFR C677T homozygous polymorphism was defined as exposure. Risk factors for endometriosis were considered confounders in a binomial logistic regression, with endometriosis diagnosis as the dependent variable. Among the 409 included patients, 106 (25.9%) cases and 303 (74.1%) controls were identified. A higher rate of MTHFR C677T homozygous polymorphism was found in patients with endometriosis (24.5% vs. 15.8%, p = 0.0453), with an adOR of 1.889 (95% CI 1.076-3.318, p = 0.0269) at the binomial logistic regression. A history of no previous pregnancy was associated with an endometriosis diagnosis (adOR 2.191, 95% CI 1.295-3.708, p = 0.0035). An MTHFR C677T homozygous polymorphism could be considered a risk factor for endometriosis. Epigenetic modifications may be the most important mechanism explaining the observed association through the processes of altered DNA methylation and reduced activity of antioxidant systems.

Inter-rater agreement of CDC criteria and ASEPSIS score in assessing surgical site infections after cesarean section: a prospective observational study. Front Surg 2023; 10:1123193. [PMID: 37675248 PMCID: PMC10477579 DOI: 10.3389/fsurg.2023.1123193] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Accepted: 08/07/2023] [Indexed: 09/08/2023] Open
Abstract
Objective To assess and compare the inter-rater agreement of the CDC criteria and the ASEPSIS score in identifying surgical site infections after cesarean section. Methods Prospective observational study including 110 patients subjected to a cesarean section at our institution. Surgical wounds were managed according to standard care and were photographed on the third, seventh, and thirtieth postoperative day or during any evaluation in case of complications. Three expert surgeons reviewed the prospectively gathered data and photographs and classified each wound using CDC criteria and the ASEPSIS score. The inter-rater agreements of CDC criteria and ASEPSIS score were determined with Krippendorff's Alpha with linear weights and compared with a confidence interval approach. Results The weighted α coefficient for CDC criteria was 0.587 (95%CI, 0.411-0.763, p < 0.001, "moderate" agreement according to Altman's interpretation of weighted agreement coefficient), while the weighted α coefficient for the ASEPSIS score was 0.856 (95%CI, 0.733-0.980, p < 0.001, "very good" agreement). Conclusion ASEPSIS score presents a "very good" inter-rater agreement for surgical site infections identification after cesarean, resulting in a more objective method than CDC criteria ("moderate" inter-rater agreement). ASEPSIS score could represent an objective tool for managing and monitoring surgical site infections after cesarean section, also by photographic evaluation.

High levels of hypusinated eIF5A in leiomyoma and leiomyosarcoma pathologies: a possible novel therapeutic target. Reprod Biomed Online 2023; 47:15-25. [PMID: 37137790 DOI: 10.1016/j.rbmo.2023.03.017] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 03/03/2023] [Accepted: 03/21/2023] [Indexed: 03/29/2023]
Abstract
RESEARCH QUESTION Is the hypusinated form of the eukaryotic translation initiation factor 5A (EIF5A) present in human myometrium, leiomyoma and leiomyosarcoma, and does it regulate cell proliferation and fibrosis? DESIGN The hypusination status of eIF5A in myometrial and leiomyoma patient-matched tissues was evaluated by immunohistochemistry and Western blotting as well as in leiomyosarcoma tissues by immunohistochemistry. Myometrial, leiomyoma and leiomyosarcoma cell lines were treated with N1-guanyl-1,7-diaminoheptane (GC-7), responsible for the inhibition of the first step of eIF5A hypunization, and the proliferation rate was determined by MTT assay; fibronectin expression was analysed by Western blotting. Finally, expression of fibronectin in leiomyosarcoma tissues was detected by immunohistochemistry. RESULTS The hypusinated form of eIF5A was present in all tissues examined, with an increasing trend of hypusinated eIF5A levels from normal myometrium to neoplastic benign leiomyoma up to neoplastic malignant leiomyosarcoma. The higher levels in leiomyoma compared with myometrium were confirmed by Western blotting (P = 0.0046). The inhibition of eIF5A hypusination, with GC-7 treatment at 100 nM, reduced the cell proliferation in myometrium (P = 0.0429), leiomyoma (P = 0.0030) and leiomyosarcoma (P = 0.0044) cell lines and reduced the expression of fibronectin in leiomyoma (P = 0.0077) and leiomyosarcoma (P = 0.0280) cells. The immunohistochemical staining of leiomyosarcoma tissue revealed that fibronectin was highly expressed in the malignant aggressive (central) part of the leiomyosarcoma lesion, where hypusinated eIF5A was also highly represented. CONCLUSIONS These data support the hypothesis that eIF5A may be involved in the pathogenesis of myometrial benign and malignant pathologies.

Abstract
Leiomyosarcoma is an aggressive soft tissue sarcoma derived from the smooth muscle cells of the uterus. We tested the effect of Romina strawberry extract treatment on three-dimensional cultured uterine leiomyosarcoma cells. We established 3D cultures in agarose gel, where the cells seeded were able to form spheroids. We performed the observation and counting of the spheroids with a phase-contrast optical microscope, finding a decrease in the number of spheroids formed in the plates after 24 and 48 h treatment with 250 µg/mL of cultivar Romina strawberry extract. We also characterized the spheroids morphology by DNA binding fluorescent-stain observation, hematoxylin and eosin stain, and Masson's trichrome stain. Finally, the real-time PCR showed a reduced expression of extracellular matrix genes after strawberry treatment. Overall, our data suggest that the fruit extract of this strawberry cultivar may be a useful therapeutic adjuvant for the management of uterine leiomyosarcoma.

Abstract
It is unknown whether human papillomavirus (HPV) status impacts the prognosis of early stage cervical glandular lesions. This study assessed the recurrence and survival rates of in situ/microinvasive adenocarcinomas (AC) according to HPV status during a 5-year follow-up. The data were retrospectively analyzed in women with available HPV testing before treatment. One hundred and forty-eight consecutive women were analyzed. The number of HPV-negative cases was 24 (16.2%). The survival rate was 100% in all participants. The recurrence rate was 7.4% (11 cases, including four invasive lesions (2.7%)). Cox proportional hazards regression showed no difference in recurrence rate between HPV-positive and HPV-negative cases (p = 0.148). HPV genotyping, available for 76 women and including 9/11 recurrences, showed a higher relapse rate for HPV-18 than HPV-45 and HPV-16 (28.5%, 16.6%, and 9.52%, p = 0.046). In addition, 60% and 75% of in situ and invasive recurrences, respectively, were HPV-18 related. The present study showed that most ACs were positive for high-risk HPV, and the recurrence rate was unaffected by HPV status. More extensive studies could help evaluate whether HPV genotyping may be considered for recurrence risk stratification in HPV-positive cases.

Should attention be paid to the cone depth in the fully visible transformation zone? Retrospective analysis of 517 patients with cervical intraepithelial neoplasia grade 3. Int J Gynaecol Obstet 2023; 161:137-143. [PMID: 36263898 DOI: 10.1002/ijgo.14520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2022] [Revised: 10/13/2022] [Accepted: 10/13/2022] [Indexed: 11/08/2022]
Abstract
OBJECTIVE The predictors of positive endocervical margin (EM) and a cone-depth cutoff value are not established in the fully visible transformation zone (TZ). The present study aimed to assess the independent variables associated with positive EM in women with high-grade cervical intraepithelial neoplasia (CIN) and fully visible TZ. METHODS The current investigation was a retrospective study including women with fully visible TZ and CIN 3 cone histology between 2014 and 2019. The sample was divided into women with positive versus those with negative EM. Univariate and multivariate analyses were performed. Finally, receiver operating characteristic curve analysis was also used. RESULTS A total of 123 of 517 women (23.8%) showed positive EM at conization. Multivariate analysis found a positive association with type 2 TZ (odds ratio [OR], 2.17 [95% confidence interval (CI), 1.19-3.94]) and lesion extension ≥2 cervical quadrants (OR, 35.57 [95% CI, 17.96-70.45]). Cone depth was inversely related to positive EM (OR, 0.71 [95% CI, 0.63-0.80]). In women with type 2 TZ and lesion extension ≥2 cervical quadrants, the cutoff value was achieved at 8-mm cone depth (area under the curve, 0.79 [95% CI, 0.67-0.90]). CONCLUSION In women with high-grade CIN and fully visible TZ undergoing conization, the lesion extension and the TZ subtype (1 or 2) should be considered. A no less than 9-mm cone depth provided a fair predictive value in achieving free EM.

Abstract
The human microbiota comprises all microorganisms, such as bacteria, fungi, and viruses, found within a specific environment that live on our bodies and inside us. The last few years have witnessed an explosion of information related to the role of microbiota changes in health and disease. Even though the gut microbiota is considered the most important in maintaining our health, other regions of the human body, such as the oral cavity, lungs, vagina, and skin, possess their own microbiota. Recent work suggests a correlation between the microbiota present during pregnancy and pregnancy complications. The aim of our literature review was to provide a broad overview of this growing and important topic. We focused on the most significant changes in the microbiota in the four more common obstetric diseases affecting women's health. Thus, our attention will be focused on hypertensive disorders, gestational diabetes mellitus, preterm birth, and recurrent miscarriage. Pregnancy is a unique period in a woman's life since the body undergoes different adaptations to provide an optimal environment for fetal growth. Such changes also involve all the microorganisms, which vary in composition and quantity during the three trimesters of gestation. In addition, special attention will be devoted to the potential and fundamental advances in developing clinical applications to prevent and treat those disorders by modulating the microbiota to develop personalized therapies for disease prevention and tailored treatments.

Abstract
The aim of the present study was to evaluate the incidence of concomitant vulvar cancers or premalignant lesions in women surgically treated for extramammary Paget's disease of the vulva (EMPDV) through a multicenter case series. The medical records of all women diagnosed with and treated for EMPDV from January 2010 to December 2020 were retrospectively analyzed. Women with EMPDV and synchronous vulvar cancer, vulvar intraepithelial neoplasia (VIN) and/or lichen sclerosus (LS) at the histology report were included in the study. A total of 69 women eligible for the present study were considered. Concomitant vulvar lesions occurred in 22 cases (31.9%). A total of 11 cases of synchronous VIN (50%) and 14 cases (63.6%) of concomitant LS were observed. One patient (4.5%) had synchronous vulvar SCC (FIGO stage 1B). Women with EMPDV and concomitant premalignant/malignant vulvar lesions had a significantly higher rate of invasive EMPDV and wider lesions with an extravulvar involvement. The specific meaning of the association between EMPDV, VIN, SCC and LS remains unclear. The potential overlapping features between different vulvar lesions highlight the importance of dedicated gynecologists and pathologists in referral centers.

Abstract
OBJECTIVE To evaluate the impact of healthcare reorganization during the severe acute respiratory syndrome coronavirus 2 pandemic on Italian colposcopy clinic activities, focusing on cervical excision procedures, follow-ups for conservative management of low-grade lesions, and follow-ups post cervical excision. METHODS Retrospective study conducted in 14 Italian colposcopy clinics. The number and clinical characteristics of cervical excisions, follow-ups for conservative management of low-grade lesions, and follow-ups after cervical excision were compared between the period March 1, 2019 to February 29, 2020 (pre-pandemic) and March 1, 2020 to February 28, 2021 (pandemic) with a Poisson regression analysis. RESULTS In the pandemic period, the number of cervical excisions was reduced by 8.8% (95% confidence interval [CI]=-15.6% to -2%; p=0.011). Excisions were less frequently performed in the operating room (-35.1%; 95% CI=-47.6% to -22.6%; p<0.001), the number of patients from spontaneous screening was reduced by -14.0% (95% CI=-23.4% to -4.6%; p=0.003), and the CO2-laser technique was used less frequently (-30%; 95% CI=-45.1% to -15.0%; p<0.001). As compared to the pre-pandemic period, the number of follow-ups for conservative management of low-grade lesions was reduced by -26.7% (95% CI=-39.0% to -14.4%; p<0.001), and the follow-up appointments after cervical excision were reduced by -51.0% (95% CI=-58.1% to -43.9%; p<0.001). CONCLUSION The most significant impact of the healthcare reorganization during the coronavirus disease 2019 pandemic was on follow-ups after cervical excision. The resumption of disrupted activities should follow a risk-based prioritization, starting from women in follow-up after cervical excision. It is advisable that the trend of performing cervical excision as an outpatient procedure is maintained in the post-pandemic period.

Endometrial Cancer Individualized Scoring System (ECISS): A machine learning-based prediction model of endometrial cancer prognosis. Int J Gynaecol Obstet 2022; 161:760-768. [PMID: 36572053 DOI: 10.1002/ijgo.14639] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 12/02/2022] [Accepted: 12/16/2022] [Indexed: 12/28/2022]
Abstract
OBJECTIVE To establish a prognostic model for endometrial cancer (EC) that individualizes a risk and management plan per patient and disease characteristics. METHODS A multicenter retrospective study conducted in nine European gynecologic cancer centers. Women with confirmed EC between January 2008 to December 2015 were included. Demographics, disease characteristics, management, and follow-up information were collected. Cancer-specific survival (CSS) and disease-free survival (DFS) at 3 and 5 years comprise the primary outcomes of the study. Machine learning algorithms were applied to patient and disease characteristics. Model I: pretreatment model. Calculated probability was added to management variables (model II: treatment model), and the second calculated probability was added to perioperative and postoperative variables (model III). RESULTS Of 1150 women, 1144 were eligible for 3-year survival analysis and 860 for 5-year survival analysis. Model I, II, and III accuracies of prediction of 5-year CSS were 84.88%/85.47% (in train and test sets), 85.47%/84.88%, and 87.35%/86.05%, respectively. Model I predicted 3-year CSS at an accuracy of 91.34%/87.02%. Accuracies of models I, II, and III in predicting 5-year DFS were 74.63%/76.72%, 77.03%/76.72%, and 80.61%/77.78%, respectively. CONCLUSION The Endometrial Cancer Individualized Scoring System (ECISS) is a novel machine learning tool assessing patient-specific survival probability with high accuracy.

Hysterectomy for cervical intraepithelial neoplasia: A retrospective observational multi-institutional study. Int J Gynaecol Obstet 2022; 159:679-688. [PMID: 35474511 PMCID: PMC9790541 DOI: 10.1002/ijgo.14233] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2022] [Revised: 04/04/2022] [Accepted: 04/21/2022] [Indexed: 12/30/2022]
Abstract
OBJECTIVE To analyze the clinical management, the outcomes, and the trend in hysterectomy rates (HR) in patients who underwent this procedure for cervical intraepithelial neoplasia (CIN). METHODS Multicentric retrospective observational study conducted on 242 patients who underwent hysterectomy for CIN between 2010 and 2020 in nine Italian institutions. Hysterectomy for invasive or micro-invasive neoplasia, sub-total hysterectomy, or trachelectomy were excluded. RESULTS A significant increase in the trend of HR for CIN was recorded (P = 0.002, r = 0.81; C.I. 95%: 0.415-0.949); HR increased from 0.46% in the year 2010 to 3.32% in 2020. The mortality rate was 0.4%, and 5% had operative complications. On definitive histopathology examination, a CIN of any grade was recorded in 71.5% of cases, and an occult invasive cancer in 1.24%. No pathology or CIN1 was found in 26.8% of cases, suggesting over treatment. During follow-up, a vaginal lesion was recorded in 5% of cases. CONCLUSION A significant increase in the number of hysterectomies performed for CIN in the last 10 years was recorded. Hysterectomy for CIN can lead to complications, risk of the onset of vaginal lesions, and risk of overtreatment, and remains, in the first instance, an unacceptable treatment, to be proposed only after adequate counseling.

Effect of the mode of delivery on the risk of endometriosis recurrence: a retrospective cohort study. Fertil Steril 2022; 118:1080-1087. [PMID: 36243596 DOI: 10.1016/j.fertnstert.2022.08.849] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Revised: 08/18/2022] [Accepted: 08/19/2022] [Indexed: 01/13/2023]
Abstract
OBJECTIVE To evaluate the risk of endometriosis recurrence according to the mode of delivery (cesarean section vs. vaginal birth) in patients who had become pregnant with a live birth after surgery for endometriosis. DESIGN A retrospective cohort study. A Cox proportional-hazards regression was performed to evaluate the risk factors for endometriosis recurrence at 36 months of follow-up after the last pregnancy. SETTING Academic hospital. PATIENT(S) Patients who have had ≥1 pregnancy with a live birth following conservative surgery for ovarian endometriosis performed from January 2009 to December 2016 at our institution. INTERVENTION(S) Patients who underwent ≥1 cesarean section after surgery for endometriosis. MAIN OUTCOME MEASURES The recurrence rate of endometriosis after live-birth pregnancies obtained after the first surgery for endometriosis. RESULTS Patients with a history of ≥1 cesarean section after surgery for endometriosis have a higher risk of endometriosis recurrence than the patients who have had a vaginal birth, with an adjusted hazard ratio of 2.25 (95% confidence interval, 1.27-3.96). CONCLUSION A cesarean section after surgery for endometriosis is associated with a twofold high risk of endometriosis recurrence with respect to vaginal birth. A different follow-up approach may be needed in those patients, and avoiding inappropriate indications for cesarean sections in pregnant patients with a history of surgery for endometriosis is necessary.

Abstract
Cervical cancer is the fourth most common cancer in women. It is the leading cause of female deaths in developing countries. Most of these cervical neoplasms are represented by squamous lesions. Cervical adenocarcinoma causes about a quarter of cervical cancers. In contrast to squamous lesions, cervical glandular disease is HPV-negative in about 15-20% of cases. HPV-negative cervical adenocarcinomas typically present in advanced stages at clinical evaluation, resulting in a poorer prognosis. The overall and disease-free survival of glandular lesions is lower than that of squamous lesions. Treatment options require definitive treatments, as fertility-sparing is not recommended. Moreover, the impact of HPV vaccination and primary HPV screening is likely to affect these lesions less; hence, the interest in this challenging topic for clinical practice. An updated review focusing on clinical and molecular characterization, prognostic factors, and therapeutic options may be helpful for properly managing such cervical lesions.

Pathogenic Role of the Sphingosine 1-Phosphate (S1P) Pathway in Common Gynecologic Disorders (GDs): A Possible Novel Therapeutic Target. Int J Mol Sci 2022; 23:ijms232113538. [PMID: 36362323 PMCID: PMC9658294 DOI: 10.3390/ijms232113538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 10/21/2022] [Accepted: 11/01/2022] [Indexed: 11/09/2022] Open
Abstract
Sphingosine 1-phosphate (S1P) is a bioactive sphingolipid, noteworthy for its involvement both in the modulation of various biological processes and in the development of many diseases. S1P signaling can be either pro or anti-inflammatory, and the sphingosine kinase (SphK)–S1P–S1P receptor (S1PR) axis is a factor in accelerating the growth of several cells, including endometriotic cells and fibrosis. Gynecologic disorders, including endometriosis, adenomyosis, and uterine fibroids are characterized by inflammation and fibrosis. S1P signaling and metabolism have been shown to be dysregulated in those disorders and they are likely implicated in their pathogenesis and pathophysiology. Enzymes responsible for inactivating S1P are the most affected by the dysregulation of S1P balanced levels, thus causing accumulation of sphingolipids within these cells and tissues. The present review highlights the past and latest evidence on the role played by the S1P pathways in common gynecologic disorders (GDs). Furthermore, it discusses potential future approaches in the regulation of this signaling pathway that could represent an innovative and promising therapeutical target, also for ovarian cancer treatment.

Preeclampsia Correlates with an Increase in Cannabinoid Receptor 1 Levels Leading to Macromolecular Alterations in Chorionic Villi of Term Placenta. Int J Mol Sci 2022; 23:12931. [PMID: 36361721 PMCID: PMC9656520 DOI: 10.3390/ijms232112931] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 10/21/2022] [Accepted: 10/25/2022] [Indexed: 09/06/2023] Open
Abstract
Preeclampsia is a human pregnancy-specific disease characterized by abnormal placentation that usually presents with maternal hypertension and proteinuria. The main hallmark of preeclampsia, impaired trophoblast migration, and the subsequent disruption of uterine arteries remodeling lead to several molecular alterations in the placental compartments with those occurring in the chorionic villi being of the utmost importance. Given the essential role of the endocannabinoid system during preimplantation and trophoblast migration, we have combined the histological and hyperspectral imaging analyses to shed light on the involvement of two cannabinoid receptors in the macromolecular alterations related to preeclampsia. The results obtained by immunohistochemistry showed a significant increase in the protein levels of cannabinoid receptor 1 (CB1) in the preeclamptic chorionic villi. However, no changes were reported regarding transient receptor potential vanilloid 1 (TRPV-1) levels either in the bulk placental samples or chorionic villi when comparing control and preeclamptic patients. Histological analysis and Fourier-transform infrared spectroscopy (FTIRI) showed an increase in collagen deposition together with higher levels of lipid peroxidation and phosphorylated compounds in the pathological villi. Since CB1 enhancement has been described as promoting fibrosis and oxidative stress in several tissues, we proposed that the higher receptor abundance in preeclampsia could be triggering similar molecular effects in preeclamptic term placentas.

Abstract
OBJECTIVE To analyze the histopathological findings in postmenopausal women who underwent hysterectomy for postsurgical cervical stenosis, evaluating the incidental findings of preinvasive or invasive uterine and cervical disease. METHODS Retrospective case series of postmenopausal women who underwent hysterectomy for postsurgical cervical stenosis at Gynecological Oncology Unit of Istituto di Ricovero e Cura a Carattere Scientifico Centro di Riferimento Oncologico Aviano-National Cancer Institute from January 2014 to January 2021. RESULTS During the study period, 36 women underwent hysterectomy for postsurgical cervical stenosis at our institution. Cervical stenosis occurred 10.2 ± 5.6 years from the onset of menopause. In particular, 26 (72.2%) patients underwent a single loop electrosurgical excision procedure or carbon dioxide (CO2)-laser conization before the onset of stenosis. The remaining 10 (27.8%) women had multiple surgical excision before the onset of stenosis. At the final histopathological analysis, 17 (47.2%) patients had a preinvasive or invasive gynecological disease. In particular, 9 cases of cervical disease (including 1 case of endocervical squamous cell carcinoma pT1a) and 6 cases of endometrial hyperplasia emerged. Also, 2 cases of tubo-ovarian diseases were found. CONCLUSIONS Postsurgical cervical stenosis is a challenging clinical condition, especially in women treated for cervical intraepithelial neoplasia or microinvasive cervical cancer. As shown, cervical stenosis can prevent an adequate gynecological follow-up and a prompt diagnosis of malignancies. Therefore, postmenopausal women with cervical stenosis should be carefully counseled, and hysterectomy could be a reasonable option, especially in those cases in which a conservative approach is not feasible, failed, or is not accepted by the patient.

Uterine leiomyoma as useful model to unveil morphometric and macromolecular collagen state and impairment in fibrotic diseases: An ex-vivo human study. Biochim Biophys Acta Mol Basis Dis 2022; 1868:166494. [PMID: 35850176 DOI: 10.1016/j.bbadis.2022.166494] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Revised: 07/07/2022] [Accepted: 07/11/2022] [Indexed: 10/18/2022]
Abstract
Collagen is one of the main components of the extracellular matrix (ECM), involved, among all, in the maintenance of the structural support of tissues. In fibrotic diseases, collagen is overexpressed, and its production determines the formation of a significantly stiffer ECM. The cross-linking of high-resolution analytical tools, able to investigate both the tridimensional organization and the secondary structure of collagen in fibrotic diseases, could be useful to identify defined markers correlating the status of this protein with specific pathological conditions. To this purpose, an innovative multidisciplinary approach based on Phase-Contrast MicroComputed Tomography, Transmission Electron Microscopy, and Fourier Transform Infrared Imaging Spectroscopy was exploited on leiomyoma samples and adjacent myometrium to characterize microstructural collagen features. Uterine leiomyoma is a common gynecological disorder affecting women in fertile age. It is characterized by a massive collagen production due to the repairing processes occurring at myometrium level, and, hence, it represents a valuable model to investigate collagen self-organization in a pathological condition. Moreover, to evaluate the sensitivity of this multidisciplinary approach, the effects of eicosapentaenoic (EPA) and docosahexaenoic (DHA) omega-3 fatty acids in collagen reduction were also investigated.

Abstract
The appearance of severe vulvovaginal varicosities (VVs) is challenging in pregnancy. The management of VVs may require a multidisciplinary approach, including radiologists, vascular surgeons, and obstetricians. We report a rare case of enormous VVs and pubic varicosities and summarize similar cases in the literature. A woman in her 20s with a full-term pregnancy visited our hospital for severe VVs and pubic varicosities. She had been in a spoke maternity unit where a cesarean section was scheduled. After a multidisciplinary evaluation, we offered her the chance to have a vaginal delivery (VD). The woman had an uneventful VD, and VVs disappeared after 40 days. A comprehensive literature search on this topic showed 11 cases of VVs during pregnancy (five VDs and six cesarean sections). The presence of VVs represented the indication for surgery in 70% of cases. Severe complications occurred in 20% of VDs vs. 50% of CSs. In pregnant women with VVs, the risk-benefit ratio suggests a chance of having VD.

Abstract
Background: This study aimed to systematically review the existing literature on uterine smooth muscle tumor of uncertain malignant potential (STUMP) to provide information about characteristics and outcomes of patients and the risk factors for recurrence over a period of 60 years (1960−2021). Methods: According to PRISMA guidelines, we searched for "uterine smooth muscle tumor of uncertain malignant potential" in PubMed (all fields) and Scopus (Title/Abstract/Keywords) databases (accessed on 1 January 2022). Relevant articles were obtained in full-text format and screened for additional references. The only filter used was the English language. Studies including full case description of patients with histopathological diagnosis of STUMP in accordance with Stanford criteria were included. Results: Thirty-four studies, including 189 cases, were included. The median age was 43 years, and in 21.5% of cases there was a recurrence of the disease. Bivariate analysis showed a significant association between use of morcellation without bag and risk of recurrence (p = 0.001). Unprotected morcellation during demolitive or conservative surgery was independently associated with a higher risk of disease recurrence with a relative risk of 2.94 (p < 0.001). A significant progressive decrease in the recurrence rate was observed over time (r = −0.671, p = 0.008). The percentage of patients who underwent surgery followed by in-bag protected morcellation significantly increased after the publication of the U.S. Food and Drug Administration alert about the risk linked to this procedure (p = 0.01). Conclusions: Unprotected morcellation of the lesion is associated with the relapse of the disease. However, this clinical condition showed a drastic decrease over time. This could likely be due to the increased awareness by surgeons of the importance of customizing surgical treatment.

Factors influencing intraoperative blood loss and hemoglobin drop during laparoscopic myomectomy: a tailored approach is possible? J OBSTET GYNAECOL 2021; 42:1404-1409.

Abstract
A retrospective study was conducted on patients subjected to laparoscopic myomectomy at our institution from January 2017 to December 2018 to identify predictive factors of blood loss. Two multiple regression models were run to predict intraoperative blood loss and haemoglobin drop. Predictors of an increased intraoperative blood loss and haemoglobin drop were the presence of three-four fibroids at ultrasound (+47 ml, p = .01; +0.58 g/dl, p = .05) and increased operative time (r = 0.57, p = .01; r = 0.01, p < .01), while predictors of a reduced intraoperative blood loss and haemoglobin drop were epinephrine injection (-50 ml, p < .01; -0.42 g/dl, p < .01), FIGO7 (-87 ml, p < .01; -0.85, p = .01), and FIGO6 (-35 ml, p < .01; -0.44, p = .02) fibroids at the ultrasound. Preoperative ultrasound evaluation is crucial in identifying patients at higher risk for blood loss, which could benefit from optimising haemoglobin values. The injection of diluted epinephrine could be proposed in selected high-risk patients. In the clinical practice, a tailored approach based on fibroids' ultrasonographic characteristics should be implemented to optimise preoperative Hb values and evaluate the use of diluted epinephrine in selected cases, reducing blood loss and the potential related complications.Impact statementWhat is already known on this subject? Laparoscopic myomectomy is the conservative surgical treatment of choice for symptomatic uterine fibroids. Still, it could represent a challenging procedure even for an experienced surgeon, with the risk of excessive blood loss, need of transfusions, prolonged operative time, and prolonged hospital stay. The knowledge of the predictive factors of blood loss is essential for patient preparation and surgical planning to reduce intraoperative and postoperative complications.What do the results of this study add? The results of the present study focus on the importance of presurgical evaluation to identify predictive factors of intraoperative blood loss and Hb drop such as the number of fibroids and the FIGO classification (at preoperative ultrasound), as well as intraoperative factors like operative time and the intramyometrial injection of diluted epinephrine.What are the implications of these findings for clinical practice and/or further research? A tailored approach based on the ultrasonographic characteristics of fibroids should be implemented to optimise preoperative haemoblobin levels.

Abstract
Objective Coronavirus disease 2019 (COVID-19) outbreak has correlated with the disruption of screening activities and diagnostic assessments. Endometrial cancer (EC) is one of the most common gynecological malignancies and it is often detected at an early stage, because it frequently produces symptoms. Here, we aim to investigate the impact of COVID-19 outbreak on patterns of presentation and treatment of EC patients. Methods This is a retrospective study involving 54 centers in Italy. We evaluated patterns of presentation and treatment of EC patients before (period 1: March 1, 2019 to February 29, 2020) and during (period 2: April 1, 2020 to March 31, 2021) the COVID-19 outbreak. Results Medical records of 5,164 EC patients have been retrieved: 2,718 and 2,446 women treated in period 1 and period 2, respectively. Surgery was the mainstay of treatment in both periods (p=0.356). Nodal assessment was omitted in 689 (27.3%) and 484 (21.2%) patients treated in period 1 and 2, respectively (p<0.001). While, the prevalence of patients undergoing sentinel node mapping (with or without backup lymphadenectomy) has increased during the COVID-19 pandemic (46.7% in period 1 vs. 52.8% in period 2; p<0.001). Overall, 1,280 (50.4%) and 1,021 (44.7%) patients had no adjuvant therapy in period 1 and 2, respectively (p<0.001). Adjuvant therapy use has increased during COVID-19 pandemic (p<0.001). Conclusion Our data suggest that the COVID-19 pandemic had a significant impact on the characteristics and patterns of care of EC patients. These findings highlight the need to implement healthcare services during the pandemic. The prevalence of patients with early-stage endometrial cancer (EC) has been lower during coronavirus disease 2019 (COVID-19) pandemic than before its onset. Further evidence is needed to assess the impact of COVID-19 pandemic on survival outcomes of EC patients.

Abstract
OBJECTIVE To evaluate the risk factors for recurrence of high-grade disease after cervical excision in women living with HIV (WLWH), with a specific interest in the role of high-risk (HR-) HPV positivity. METHODS Multicentric retrospective study conducted on WLWH who underwent cervical excision between January 1987 and June 2017 in six Italian institutions. The rate of high-grade recurrence was determined. Risk factors for recurrence and HR-HPV positivity were determined with the Log-rank test and Cox proportional hazards regression models. RESULTS A total of 271 WLWH were included in the final analysis. A high-grade recurrence was found in 58 (21.4%) patients. Age 41 years or more at inclusion and HR-HPV positivity during follow up were independently associated with a higher risk of disease recurrence with relative risks of 4.15 (95% confidence interval [CI] 2.01-8.58, P < 0.001) and 5.18 (95% CI 2.12-12.67, P < 0.01), respectively. Age 41 years or more (relative risk 1.75, 95% CI 1.01-3.04, P = 0.047) resulted as a risk factor for HR-HPV positivity during follow up. CONCLUSION HR-HPV positivity is a risk factor for recurrence after cervical excision in WLWH. Women older than 41 years may benefit from a long-term yearly follow up. Future studies regarding HPV vaccination after treatment in WLWH may be useful, considering the protective role of the higher probability of HPV negativity in vaccinated women.

Foetal ductus arteriosus constriction unrelated to non-steroidal anti-Inflammatory drugs: a case report and literature review. Ann Med 2021; 53:860-873.

Abstract
Foetal ductus arteriosus (DA) constriction can be found in complex foetal heart malformations, but rarely as an isolated defect. Although many cases of DA constriction are usually related to Non-steroidal Anti-Inflammatory Drugs (NSAIDs) maternal intake, other causes remain without an established aetiology and are referred to as idiopathic. Recently, a wide range of risks factors or substances (polyphenol-rich foods intake, naphazoline, fluoxetine, caffeine and pesticides) showed a definitive effect upon the pathway of inflammation, causing DA constriction. We report a case of a premature DA constriction in a woman whose possible risk factor was identified in her maternal occupational exposure to solvents and a comprehensive literature review of 176 cases of NSAID-unrelated DA constriction. A 30-year-old Asian woman was referred to our institution at 33 gestational weeks and 0 days because of suspicion of premature DA constriction. The woman had no history of medication intake, including NSAIDs, alcohol, tobacco or polyphenol-rich-food consumption during pregnancy. A detailed foetal echocardiography revealed a normal cardiac anatomy with hypertrophic, hypokinetic and a dilated right ventricle due to right pressure overload, holosystolic tricuspid regurgitation, and, at the level of the DA, high systolic and diastolic velocities, indicating premature ductal restriction. The right outflow showed dilatation of the pulmonary artery with narrow DA. An urgent caesarean section was performed at 33 gestational weeks and 4 days due to worsening of DA PI and signs of right pressure overload, despite the interruption of exposure to solvents. We assume a relationship exists between premature DA constriction and a maternal occupational exposure to solvents. This hypothesis is reinforced by the presence of associated foetal malformations in in two of the patient's children. Further research is needed to confirm the role of exposure to solvents and toxic chemicals in the pathogenesis of DA constriction, also with experimental animal models.KEY MESSAGESMany cases of DA constriction are usually related to Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) maternal intake.A wide range of risks factors or substances (polyphenol-rich foods intake, naphazoline, fluoxetine, caffeine and pesticides) can cause foetal DA constriction.Further investigation are needed to confirm the role of maternal exposure to solvents in the pathogenesis of DA constriction.

Phytoprogestins: Unexplored Food Compounds with Potential Preventive and Therapeutic Effects in Female Diseases. Nutrients 2021; 13:nu13124326. [PMID: 34959877 PMCID: PMC8705436 DOI: 10.3390/nu13124326] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Revised: 11/25/2021] [Accepted: 11/29/2021] [Indexed: 12/12/2022] Open
Abstract
In recent years, there has been an increasing interest in natural therapies to prevent or treat female diseases. In particular, many studies have focused on searching natural compounds with less side effects than standard hormonal therapies. While phytoestrogen-based therapies have been extensively studied, treatments with phytoprogestins reported in the literature are very rare. In this review, we focused on compounds of natural origin, which have progestin effects and that could be good candidates for preventing and treating female diseases. We identified the following phytoprogestins: kaempferol, apigenin, luteolin, and naringenin. In vitro studies showed promising results such as the antitumoral effects of kaempferol, apigenin and luteolin, and the anti-fibrotic effects of naringenin. Although limited data are available, it seems that phytoprogestins could be a promising tool for preventing and treating hormone-dependent diseases.

An online survey on emotions, impact on everyday life, and educational needs of women with HPV positivity or abnormal Pap smear result. Medicine (Baltimore) 2021; 100:e27177. [PMID: 34766557 PMCID: PMC8589238 DOI: 10.1097/md.0000000000027177] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Accepted: 08/20/2021] [Indexed: 01/05/2023] Open
Abstract
This study aimed to evaluate the emotional path, impact on everyday life, and adequacy of patient education throughout the diagnostic and therapeutic journey of women who received a positive human papillomavirus (HPV) test or Pap smear result.An online survey was designed to determine the demographic characteristics, dominant feelings throughout the diagnostic and therapeutic procedures, major lifestyle changes, impact on social life, and perceived adequacy of patient information in Italian women with a positive HPV test or abnormal cervical cytology result. In this study, the phases of the "patient's journey" included the initial test, waiting for colposcopy or biopsy, waiting for surgery, and follow-up.Anxiety, worry, and fear were the most frequently cited emotions during the initial tests and intervals between procedures. Anxiety and fear gradually decreased during the journey until surgery, and higher levels of optimism were observed postsurgery. The most frequently reported lifestyle changes were attempts to boost the immune system, increased precautions in sexual practices, and dietary changes. Social life is affected by changes in sexual and intimate relationships with partners. Women reported receiving insufficient patient education on the diagnosis and its implications, progression, management, personal care, and resolution.Significant attention should be given to the psychosocial aspects of the entire patient journey after receiving a positive HPV test or an abnormal Pap smear result. It is essential to establish a good rapport between patients and healthcare professionals, and to educate women regarding the condition by minimizing the gap between the perceived and desired adequacy of information.

Hop and artichoke extracts inhibit expression of extracellular matrix components in uterine leiomyoma cells. F&S SCIENCE 2021; 2:407-418. [PMID: 35559863 DOI: 10.1016/j.xfss.2021.09.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 08/24/2021] [Accepted: 09/01/2021] [Indexed: 06/15/2023]
Abstract
OBJECTIVE To screen 14 different plant extracts for their antifibrotic effect on human primary leiomyoma and healthy myometrial cells. DESIGN Preclinical study. SETTING University research laboratory. PATIENT(S) Human uterine leiomyoma and matched myometrial tissues were obtained from Caucasian premenopausal women with symptomatic uterine fibroids at the time of hysterectomy. INTERVENTION(S) Primary human leiomyoma and myometrial cells were cultured in the absence or presence of the plant extracts. MAIN OUTCOME MEASURE(S) Quantification of the expression of extracellular matrix components, such as fibronectin 1 (FN1), collagen type I alpha 1 (COL1A1), and versican (VCAN), and the profibrotic growth factor activin A or inhibin beta A subunit (INHBA). RESULT(S) The cells were treated with the 14 extracts for 48 hours, and we measured FN1 messenger RNA (mRNA) expression. Of the 14 extracts, about (ABO) ABO-2 (hop) and ABO-9 (artichoke) significantly reduced FN1 expression in both the cell types. Next, we evaluated the effect of fractions of these 2 extracts on the mRNA expression of FN1 and other extracellular matrix components, such as COL1A1, VCAN, and INHBA, in leiomyoma and myometrial cells. We found that ABO-2 (hop) and ABO-9 (artichoke) as well as their fractions, ABO-AR-2016-015 (fraction of ABO-2) and ABO-AR-2014-168 (fraction of ABO-9), reduced the mRNA expression of FN1, COL1A1, VCAN, and INHBA in primary leiomyoma cells. In primary myometrial cells, the mRNA expression of FN1, COL1A1, VCAN, and INHBA was not greatly affected. CONCLUSION(S) These results suggest that the hop and artichoke extracts possess antifibrotic properties and support additional evaluation using in vivo models.

Trend of HPV 16/18 Genotypes in Cervical Intraepithelial Neoplasia Grade 3: Data for 2007-2018. Infect Drug Resist 2021; 14:3763-3771. [PMID: 34557001 PMCID: PMC8453441 DOI: 10.2147/idr.s326851] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Accepted: 08/31/2021] [Indexed: 11/23/2022] Open
Abstract
Aim In the post-vaccination era, the starting age and time intervals of cervical screening could change (older age and longer screening intervals). This scenario may be achieved by significantly reducing human papillomavirus (HPV) 16/18 prevalence (genotypes included in the current vaccines). In this regard, assessing the trend over time of these HPV infections in high-grade cervical lesions can provide information on the objective. The present study aimed to evaluate the trend of HPV 16/18 over the years 2007–2018 in women with cervical intraepithelial neoplasia (CIN) grade 3. Methods This is a retrospective multi-institutional study including HPV genotyped and unvaccinated women under 30 with CIN3. The sample was divided into the following periods: 2007–2010, 2011–2014, 2015–2018. HPV genotypes were grouped in genotypes 16/18, genotypes 31/33/35/52/58/67 (genetically related to HPV16), genotypes 39/45/59/68/70 (genetically related to HPV18), genotypes 31/33/45/52/58 (high-risk types included in the nonavalent vaccine), possibly carcinogenic HPV (genotypes 26/30/53/67/70/73/82/85), low-risk HPV (genotypes 6/11/40/42/43/44/54/55/61). The trend between periods and HPV genotypes was measured using the Cochran–Armitage test for trend. Results The final analysis included 474 participants. HPV 16/18 prevalence decreased significantly over the years (77.8% vs 68.9% vs 66.0%, respectively, Ptrend=0.027). Possibly carcinogenic HPV (genotypes 26/30/53/67/70/73/82/85) showed a significant negative prevalence trend over time (4.9% vs 1.1% vs 1.3%, respectively, Ptrend=0.046). Finally, there was a significant positive trend over the years for high-risk HPV genotypes 31/33/45/52/58 in women under 25 (9.9% vs 17.0% vs 24.0%, respectively, Ptrend=0.048). Conclusion The prevalence of CIN3 lesions related to HPV 16/18 genotypes decreased over time from 2007 to 2018. These data highlight a herd effect of the HPV vaccine. However, fifteen years after HPV vaccine introduction, we are still a long way from herd immunity. The increase in high-risk types 31/33/45/52/58 will need to be reassessed when the nonavalent vaccine impact will be more reliable.

Abstract
Uterine fibroids are the most common cause of solid pelvic tumours, occurring in 20-30% of fertile women and presenting clinical complications that seriously affect women's health. They commonly cause severe symptoms, such as heavy, prolonged menstrual bleeding and anaemia. The study of microscopic and macroscopic vascular aspects of uterine fibroids is important for understanding the clinical manifestations of uterine fibroids, for predicting the effectiveness of alternative treatments to surgery, i.e. uterine artery embolization, for improving surgery outcomes and for carrying out a differential diagnosis with other benign conditions, e.g. adenomyosis, or malignancy, e.g. leiomyosarcoma, and to develop new therapeutic approaches. In this review, current knowledge of how the vascular network and angiogenesis are implied in the formation of uterine fibroids and in the pathogenesis of related symptoms is explored, and evidence on the role of ultrasound in evaluating fibroid vascularization is summarized. This review combines anatomical, morphological and biomolecular information related to angiogenic mechanisms with diagnostic and clinical information, highlighting the various interconnections. Uterine and fibroid vascularization need further investigation to gain a deeper understanding of the pathogenetic elements that lead to the formation of uterine fibroids and their clinical manifestations.

The Impact of 9-Valent HPV Vaccination on Couple Infertility Prevention: A Comprehensive Review. Front Med (Lausanne) 2021; 8:700792.

Abstract
A comprehensive literature review was performed to determine the relationship between HPV infection and infertility and the eventual role of the 9-valent vaccine for infertility prevention. The search was extended from January 1997 through July 2021. Data collected from selected articles focused on three main topics: statistical associations between HPV prevalence and assisted reproductive technology (ART) outcome, association between HPV and characteristics of semen, and associations between HPV and miscarriage. Articles that identified HPV genotypes were selected for this review to study the possible role of the 9-valent vaccine in infertility prevention. To date, there is no agreement on the implication HPV female infection has on the fertility and miscarriage rate. Although it can be stated that HPV prevalence among couples with infertility undergoing ART treatment is consistent, it does not seem to affect the performance of oocytes. Otherwise, HPV infection affects sperm parameters, in particular spermatozoa motility. When an association can be found, most cases of HR-HPV involved are those included in the 9-valent vaccine. The correlation between HPV male infection both with asthenozoospermia and increased risk of pregnancy loss could recommend the extension of anti-HPV vaccination to adolescent males along with cancer prevention. Despite the fact that the relation between 9-valent HPV genotypes involved in female infection and miscarriage/infertility is not clear, the impact of this virus on health reproduction is evident. Considering this, the importance of HPV vaccination in adolescent females is confirmed. A vaccine efficacy study could be useful to confirm the importance of primary prevention for couple reproductive health.

Malignant Transformation of Postmenopausal Endometriosis: A Systematic Review of the Literature. Cancers (Basel) 2021; 13:4026. [PMID: 34439184 PMCID: PMC8394809 DOI: 10.3390/cancers13164026] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 08/08/2021] [Accepted: 08/09/2021] [Indexed: 11/16/2022] Open
Abstract
Objective: This study aimed to systematically review the existing literature on malignant transformation of postmenopausal endometriosis to provide information about patient characteristics, hormonal replacement therapy (HRT) use, and outcomes over a period of 52 years (1969-2021). Methods: According to PRISMA guidelines, we searched for (endometriosis OR endometriotic) AND (cancer OR malignancy OR malignant transformation) AND (menopause OR menopausal OR postmenopause OR postmenopausal) in Pubmed (all fields) (accessed on 12 February 2021) and Scopus (Title/Abstract/Keywords) (accessed on 12 February 2021) databases. The only filter used was the English language. Relevant articles were obtained in full-text format and screened for additional references. Eligibility/inclusion criteria: studies including full case description of malignant transformation of endometriosis-related lesions in postmenopause. Results: 75 studies, including 90 cases, were retrieved. The mean age was 55.8 ± 8.5 years. Overall, about 65% of women had a positive personal history of endometriosis/adenomyosis, and 64% of women underwent previous hysterectomy ± bilateral salpingo-oophorectomy. Forty-nine of 74 women used HRT (66.2%). Among the women who used HRT, estrogen-only treatment was taken by approximately 75%. Duration of HRT was longer than five years in 63.3% of cases. About 70% of subjects had histology of endometrioid adenocarcinoma or clear cell carcinoma. Follow-up outcome, available for 61 women, showed a survival rate of 78.7%, recurrence of 9.8%, death of 11.5%. The duration of follow-up had a median of 12 months (interquartile range, 6.75-25 months). Interestingly, over the years of case publication there was a significant inverse correlation with previous history of endometriosis (r = -0.28, p = 0.007), HRT use (r = -0.31, p = 0.006), and previous definitive surgery (r = -0.42, p < 0.001). Conclusions: In the malignant transformation of postmenopausal endometriosis, there are some recurrent clinical conditions: previous endometriosis, major definitive surgery before menopause, and estrogen-only HRT for a relatively long time. However, these clinical conditions have shown a drastic decrease over time. This could likely be the consequence of different attitudes and management of gynecologists linked to up-to-date scientific evidence about the use of major surgery in gynecological pathologies. Malignant transformation of postmenopausal endometriosis is a clinical challenge to be explored further.

Abstract
BACKGROUND/AIM Clear cell carcinoma of the abdominal wall is a sporadic event. To date, about thirty cases have been reported in the literature. This article provides a case report and literature review of an infrequent occurrence with poor prognosis. CASE REPORT A 45-year-old woman with pelvic pain and an abdominal mass came to our attention. Her medical history was notable for two previous cesarean sections. Physical examination revealed a smooth, multilocular mass measuring about 20 cm, arising from the previous surgical scar. Histology revealed clear-cell carcinoma resulting from the transformation of abdominal wall endometriosis. Given the disease extent, the patient underwent front-line chemotherapy. After several and multiple chemotherapy regimens, there was a disease progression that resulted in the death of the patient in 7 months. The literature review showed that a previous cesarean section was present in 91% of cases. Besides, approximately 26.5% of women died within 12 months of being diagnosed. The mean age of women was 45.88 years, while the average size of the lesion was 11 cm. CONCLUSION Clear cell carcinoma is a rare but occurring event. Middle-aged women showing an abdominal wall mass in close relation with a surgical scar from a previous cesarean section must be promptly investigated. Treatment options usually include surgery and chemotherapy with poor results.

Macrophages and Immune Responses in Uterine Fibroids. Cells 2021; 10:cells10050982.

Abstract
Uterine fibroids represent the most common benign tumors of the uterus. They are considered a typical fibrotic disorder. In fact, the extracellular matrix (ECM) proteins—above all, collagen 1A1, fibronectin and versican—are upregulated in this pathology. The uterine fibroids etiology has not yet been clarified, and this represents an important matter about their resolution. A model has been proposed according to which the formation of an altered ECM could be the result of an excessive wound healing, in turn driven by a dysregulated inflammation process. A lot of molecules act in the complex inflammatory response. Macrophages have a great flexibility since they can assume different phenotypes leading to the tissue repair process. The dysregulation of macrophage proliferation, accumulation and infiltration could lead to an uncontrolled tissue repair and to the consequent pathological fibrosis. In addition, molecules such as monocyte chemoattractant protein-1 (MCP-1), granulocyte macrophage-colony-stimulating factor (GM-CSF), transforming growth factor-beta (TGF-β), activin A and tumor necrosis factor-alfa (TNF-α) were demonstrated to play an important role in the macrophage action within the uncontrolled tissue repair that contributes to the pathological fibrosis that represents a typical feature of the uterine fibroids.

Cervical Cancer Screening Guidelines in the Postvaccination Era: Review of the Literature. JOURNAL OF ONCOLOGY 2020; 2020:8887672. [PMID: 33204265 PMCID: PMC7661145 DOI: 10.1155/2020/8887672] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Revised: 10/09/2020] [Accepted: 10/24/2020] [Indexed: 12/15/2022]
Abstract
Cervical cancer is relatively rare in high-income countries, where organized screening programs are in place, as well as opportunistic ones. As the human papillomavirus (HPV) vaccination rates increase, the prevalence of cervical precancers and cancers is going to decrease rapidly very soon, even if, in the most optimistic scenario, it is unlikely that optimal vaccination coverage will be achieved. Then, the optimal screening paradigm for cervical cancer prevention in the postvaccination era is still debated. Screening guidelines are being developed with the aim of reducing the number of tests a woman needs during her lifetime, in order to receive the maximum benefit from screening, while decreasing potential harms that may result with the use of a screening strategy (overdiagnosis, overtreatment, anxiety, and costs). With this purpose in mind, new management guidelines for cervical cancer screening abnormalities are recommendations based on risks, not on results. This review aims to summarize the process that led to the introduction of the HPV DNA test in screening programs and the different screening strategies. Moreover, it aims to introduce the new risk-based guidelines for the future, where full HPV genotyping can resize the risk on the basis of specific high-risk genotypes. In the same way, the data regarding HPV vaccination could be introduced as soon as women vaccinated with the nonavalent vaccine reach the screening age, with the recommendation of a prolonged screening interval.

Abstract
AIM The present study aimed to perform an initial validation of the Thymic-Thoracic Ratio as a sonographic marker of conotruncal defects in non-syndromic fetuses and to assess the possible correlation between the grade of thymic hypoplasia and the severity of conotruncal defects. METHODS The study was conducted between January and June 2018 on singleton pregnant women who underwent fetal echocardiography at our institution. Fetuses with a diagnosis of conotruncal defects without 22q11.2 deletion composed the study group, while healthy appropriate for gestational age fetuses composed the control group. The Thymic-Thoracic Ratio was measured in all included fetuses and compared between the study and control group. A ROC curve analysis to evaluate the diagnostic performance of Thymic-Thoracic Ratio toward the diagnosis of conotruncal defects was performed, with determination of sensitivity, specificity, PPV, NPV, positive likelihood ratio, and negative likelihood ratio. The severity of conotruncal defects was defined with the Aristotle score in each newborn who underwent a surgical operation. The correlation between Thymic-Thoracic Ratio and Aristotle score was assessed. RESULTS During the study period, 23 fetuses with conotruncal defects without 22q11.2 deletion constituted the study group, and 67 healthy appropriate for gestational age fetuses were included in the control group. The T-T ratio of the study group was significantly lower than the control group (0.32 ± 0.08 vs. 0.41 ± 0.08, p < .001). The ROC curve analysis showed an AUC of 0.80 (95% CI, 0.71-0.89, p < .001) and a T-T ratio cutoff value of 0.35 for the identification of a CTD, with a sensibility of 73.9% (95% CI: 51.6-89.8%), a specificity of 79.1% (95% CI: 67.4-88.1%) a PPV of 54.8% (95% CI: 41.8-67.3%), a NPV of 89.8% (95% CI: 81.5-94.7), a positive likelihood ratio of 3.54 (95% CI 2.09-5.98), and a negative likelihood ratio of 0.33 (95% CI 0.16-0.66). A negative correlation between Aristotle score and T-T ratio was found, with a Kendall-Tau coefficient of -0.41, p = .04. CONCLUSION T-T ratio measurement could be useful to identify fetuses at higher risk of conotruncal heart diseases, even without chromosomic deletion, with a cutoff of 0.35. Since a lower T-T ratio seems to be related to a worse surgical neonatal prognosis, it could be possible to provide effective counseling and refer patients to high-specialized centers for fetal echocardiography and cardiac surgery.

Abstract
Background: Up to 40% of women with atypical endometrial hyperplasia (AEH) can reveal endometrial cancer (EC) at hysterectomy. The pre-operative endometrial sampling method (ESM) and some independent cancer predictors may affect this outcome. The present study aimed to compare the rate of EC at hysterectomy in women with AEH undergoing dilation and curettage (D&C), hysteroscopically-guided biopsy (HSC-bio), or hysteroscopic endometrial resection (HSC-res). The secondary outcome was to compare the reliability of ESMs in women showing independent variables associated with EC. Methods: Two-hundred-and-eight consecutive women with AEH and undergoing hysterectomy between January 2000 and December 2017 were analyzed retrospectively. Based on pre- and post-test probability analysis for EC, three ESMs were compared: D&C, HSC-bio, and HSC-res. Univariate and multivariate analyses were performed to assess risk factors predicting cancer on final histology. Finally, the patient’s characteristics were compared between the three ESM groups. Results: D&C and HSC-bio included 75 women in each group, while HSC-res included 58 women. Forty-nine women (23.6%) revealed cancer at hysterectomy (pre-test probability). Post-test probability analysis showed that HSC-res had the lowest percentage of EC underestimation: HSC-res = 11.6%; HSC-bio = 19.5%; D&C = 35.3%. Patient characteristics showed no significant differences between the three ESMs. Multivariate analysis showed that body mass index ≥40 (Odds Ratio (OR) = 19.75; Confidence Intervals (CI) 2.193–177.829), and age (criterion > 60 years) (OR = 1.055, CI 1.002–1.111) associated significantly with EC. In women with one or both risk factors, post-test probability analysis showed that HSC-res was the only method with a lower EC rate at hysterectomy compared to a pre-test probability of 44.2%: HSC-res = 19.96%; HSC-bio = 53.81%; D&C = 63.12%. Conclusions: HSC-res provided the lowest rate of EC underestimation in AEH, also in women showing EC predictors. These data may be considered for better diagnostic and therapeutic planning of AEH.

Expert consensus from the Italian Society for Colposcopy and Cervico-Vaginal Pathology (SICPCV) for colposcopy and outpatient surgery of the lower genital tract during the COVID-19 pandemic. Int J Gynaecol Obstet 2020; 149:269-272. [PMID: 32270477 PMCID: PMC9087780 DOI: 10.1002/ijgo.13158] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Revised: 04/05/2020] [Accepted: 04/06/2020] [Indexed: 11/08/2022]
Abstract
In the context of the COVID-19 pandemic, patients need to be evaluated within 2-4 weeks in the following cases: cytology result of "squamous cell carcinoma," "atypical glandular cells, favor neoplastic," "endocervical adenocarcinoma in situ," or "adenocarcinoma"; histopathological diagnosis of suspected invasion from cervical/vaginal biopsy, or invasive disease after a cervical excision procedure, vaginal excision, or vulvar biopsy/excision; sudden onset of strongly suggestive symptoms for malignancy. Digital imaging technologies represent an important opportunity during the COVID-19 pandemic to share colposcopic images with reference centers, with the aim of avoiding any concentration of patients. All patients must undergo screening for COVID-19 exposure and should wear a surgical mask. A high-efficiency filter smoke evacuation system is mandatory to remove surgical smoke. Electrosurgical instruments should be set at the lowest possible power and not be used for long continuous periods to reduce the amount of surgical smoke. The following personal protective equipment should be used: sterile fluid-repellant surgical gloves, an underlying pair of gloves, eye protection, FFP3 mask, surgical cap, and gown. The colposcope should be protected by a disposable transparent cover. A protective lens that must be disinfected after each use should be applied. The use of a video colposcope should be preferred.

Quercetin and indole-3-carbinol inhibit extracellular matrix expression in human primary uterine leiomyoma cells. Reprod Biomed Online 2020; 40:593-602. [PMID: 32276890 DOI: 10.1016/j.rbmo.2020.01.006] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Revised: 12/19/2019] [Accepted: 01/10/2020] [Indexed: 01/03/2023]
Abstract
RESEARCH QUESTION What is the effect of quercetin and indole-3-carbinol (I3C) on extracellular matrix expression, cell migration and proliferation in human myometrial and uterine leiomyoma cells. DESIGN Myometrial and leiomyoma cells were treated with quercetin or I3C at different concentrations (10 µg/ml; 50 µg/ml; 100 µg/ml; and 250 µg/ml) for 48 h to measure mRNA and protein expressions of extracellular matrix (collagen 1A1, fibronectin and versican), as well as cell migration and the proliferation rate. RESULTS Quercetin decreased mRNA levels of collagen 1A1 in myometrial (P < 0.0001) and leiomyoma cells (P < 0.0001). Quercetin reduced mRNA and protein levels of fibronectin in myometrial cells (P < 0.05) and fibronectin protein in leiomyoma cells (P < 0.05). I3C reduced collagen 1A1 mRNA levels in myometrial (P < 0.05) and leiomyoma cells at higher dose (P < 0.05). The protein levels of fibronectin were also reduced in both myometrial and leiomyoma cells with highest dose of I3C (P < 0.05), although mRNA levels were not affected in leiomyoma cells. Neither quercetin nor I3C treatment altered versican mRNA levels in both cell types. A significant reduction of the migration of both myometrial and leiomyoma cells in response to quercetin was observed (P < 0.05) and I3C (P < 0.05 for myometrial and P < 0.01 for leiomyoma cells) treatment. Both quercetin and I3C significantly reduced myometrial cell proliferation (P < 0.05). CONCLUSIONS The in-vitro anti-fibrotic, anti-migratory and anti-proliferative effects of quercetin and I3C form the scientific basis for developing new therapeutic, preventive agents, or both, for uterine leiomyomas.

Comparison of uterine fibroids' growth pattern during pregnancy according to fetal sex: an observational study. Biol Sex Differ 2019; 10:53. [PMID: 31775886 PMCID: PMC6880545 DOI: 10.1186/s13293-019-0266-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2019] [Accepted: 10/01/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND To investigate the effect of fetal sex on fibroids' growth during pregnancy according to the hCG serum levels METHODS: Observational study conducted from January 2007 to December 2016 on women with ultrasound identification of uterine fibroids who had a pregnancy within 1 year from diagnosis. The fibroids diameter was determined during the pre-pregnancy ultrasound, early first trimester (5-7 weeks), late first trimester (11-13 weeks), second trimester (19-21 weeks), and third trimester (31-33 weeks). The diameter growth was calculated in each interval between two ultrasounds. The hCG serum levels were determined both in early and late first trimester. The correlation between hCG levels and fibroid diameter was evaluated. Obstetric outcomes collected were gestational weeks at birth and the rate of cesarean section. Neonatal outcomes were birthweight and Apgar score at 1 min. RESULTS Eighty-seven of the included women had a male fetus, and 70 had a female fetus. A progressive increase of fibroid diameter was observed from pre-pregnancy to second trimester for both fetal sexes. In third trimester, the mean ± SD fibroid diameter of female fetuses showed a slowdown, while the mean ± SD fibroid diameter of male fetuses continued to grow. Women carrying a female fetus presented a higher fibroid diameter in early first trimester (33.5 ± 13.3 mm vs 27.4 ± 11.0 mm, p < 0.01), late first trimester (40.2 ± 13.9 mm vs 34.6 ± 11.7 mm, p < 0.01), and second trimester (40.5 ± 14.9 mm vs 34.7 ± 10.3 mm, p < 0.01). The hCG serum levels resulted higher in women with a female fetus: 61406 (50554-71760) mU/ml vs 46016 (37160-56744) mU/ml (p < 0.01). A positive correlation between hCG levels and fibroid diameter was found both for male and female fetuses (male r = 0.77, 95% CI 0.71-0.82, p < 0.01 and female r = 0.82, 95% CI 0.76-0.86, p < 0.01). CONCLUSION Women with female fetus seem to have a higher growth of fibroids up to second trimester of pregnancy. This process may be mediated by the higher serum hCG levels found in women expecting a female fetus.

Adenocarcinoma in situ of the uterine cervix: Clinical practice guidelines from the Italian society of colposcopy and cervical pathology (SICPCV). Eur J Obstet Gynecol Reprod Biol 2019; 240:273-277. [PMID: 31352128 DOI: 10.1016/j.ejogrb.2019.07.014] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2019] [Revised: 07/10/2019] [Accepted: 07/12/2019] [Indexed: 10/26/2022]
Abstract
OBJECTIVE to provide a practical tool for the evidenced-based management of adenocarcinoma in situ (AIS) of the uterine cervix, a challenging diagnosis encountered by colposcopists in their daily practice. METHODS the proposed recommendations were drafted by the Italian Society of Colposcopy and Cervical Pathology (SICPCV) based on comprehensive reviews of previous guidelines, large uncontrolled studies, metanalysis, and sytematic reviews. The quality Level and the strength of the recommendations were graded and respectively expressed in Roman numbers (I-VI) and letters (A-E). RESULTS Women with all subcategories of abnormal glandular cells and AIS on cervical citology should be offered colposcopy with endocervical sampling (Strength of recommendation: A). In women with cytological AIS and negative colposcopy or endocervical curettage, an excisional treatment under colposcopic guidance is recommended (Strength of recommendation: A). If immediate post-conization endocervical sampling is positive, further conization is indicated (Strength of recommendation: C). In women who desire to preserve fertility with positive cone margins, further conization should be performed (Strength of recommendation: B). If colposcopy is adequate, a cylindrical excision that includes the whole transformation zone and at least 1-1.5 cm of endocervix beyond the squamous-columnar junction should be performed (Strength of recommendation: B). If colposcopy is inadequate, it is recommended that conization includes the whole transformation zone with a depth of 20-25 mm (Strength of recommendation: B). Hysterectomy is the standard definitive treatment for AIS in women who do not wish to preserve fertility (Strength of recommendation: B). CONCLUSION the proposed recommendations should enable clinicians to correctly diagnose, treat and follow AIS patients, avoiding mismanagement.

The association between childbirth, breastfeeding, and uterine fibroids: an observational study. Sci Rep 2019; 9:10117. [PMID: 31300699 PMCID: PMC6626014 DOI: 10.1038/s41598-019-46513-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2019] [Accepted: 06/21/2019] [Indexed: 12/14/2022] Open
Abstract
The aim of this study was to investigate the effect of childbirth and breastfeeding on uterine fibroids and to identify the factors associated with size variations. This was a monocenter observational study carried on women with a sonographic diagnosis of uterine fibroids from January 2007 to December 2016, with no indication for immediate treatment, and who became pregnant within one year from diagnosis. All patients were re-evaluated six months after delivery. Fibroid diameters were compared between pre-pregnancy period, first, second, third trimester and post-delivery. The rate of "regressed" (growth of diameter <-40%), "unchanged" (growth of diameter between -40% and +40%) or "increased" (growth of diameter >+40%) fibroids at the post-delivery evaluation with respect to the pre-pregnancy state was calculated. One-hundred fifty-seven women were included in the final analysis. At the post-delivery ultrasound, a significant reduction of the fibroid diameter with respect to all previous examinations was observed, and there was no evidence of 67 (37.2%) fibroids. Ongoing breastfeeding was positively associated with an "unchanged" or "regressed" fibroid diameter (adOR 3.23, 95%CI: 1.35-7.70, p < 0.01). Smaller pre-gravidic fibroids were more likely to return to pre-pregnancy dimensions or to regress, with a cut-off of 32 mm for lactating women and of 26 mm for non-lactating women. In conclusion, fibroids seem to return to pre-pregnancy dimensions or to regress in the post-partum period. This process may be sustained by uterine involution and hormonal variations, with an additional role of breastfeeding.

Abstract
OBJECTIVE To evaluate the risk of progression to high-grade squamous intraepithelial lesion (HSIL) (CIN2-3) or invasive cancer in women with histopathological diagnosis of low-grade squamous intraepithelial lesion (LSIL) (CIN1), managed in a long-term observational approach up to 5 years. DESIGN Retrospective cohort study. SETTING Four tertiary referral hospital. PARTICIPANTS 434 women with adequate colposcopy and complete colposcopic charts were included in the present analysis. Women with glandular lesions on the referral cytology or previous diagnosis of cervical dysplasia or invasive cervical cancer or with synchronous vaginal, or with HIV infection or immunodepression were excluded. PRIMARY AND SECONDARY OUTCOME MEASURES The main study outcome was the rate of progression to histopathological HSIL (CIN2-3) or invasive cancer at any time during 5 years of follow-up. The possible risk factors were also evaluated. As secondary outcome, we analysed the possible risk factors at the 24-month evaluation for histopathological HSIL (CIN2-3) or invasive cancer progression between 2 and 5 years from initial diagnosis. RESULTS A progression to histopathological HSIL (CIN2-3) was found in a total of 32 (7.4%) cases during 5 years of follow-up. A histopathological diagnosis of HSIL (CIN3) was found in four patients (0.9%) and no case of invasive cancer was detected. High-grade cytology at inclusion and the presence of a positive high-risk human papillomavirus (HR-HPV) DNA test at 2 years from inclusion maintained a significant correlation with the risk of histopathological progression to HSIL (CIN2-3). CONCLUSIONS The results of our study showed a low rate (7.4%) of histopathological progression to HSIL (CIN2-3) in women with LSIL (CIN1) diagnosis during long-term follow-up up to 5 years. In case of positive HR-HPV DNA test at the 2 years evaluation an excisional treatment could be the preferred choice to prevent progression to HSIL (CIN2-3) in the following years, preferring a continuation of follow-up in case of HR-HPV DNA negative result.
