RESUMO
INTRODUCTION: Ovarian cancer (OC) represent nearly 4% of gynecologic malignancies and it is often diagnosed at advanced stage. Diaphragmatic surgery, a fundamental step of advanced stage ovarian cancer (ASOC) debulking surgery, is associated with a high post-operative complication incidence, which is supposedly reduced with thoracostomy tube placement. We assessed the role of intra-operative thoracostomy tube placement, as a prevention measure for post-operative complications, after diaphragmatic resection. METHODS: This was a single center prospective randomized trial. Ovarian cancer patients, who underwent mono-lateral diaphragmatic resection, were randomized 1:1 into two arms. Arm A included patients receiving intra-operative thoracostomy tube placement (TP); Arm B patients did not receive thoracostomy tube placement (NTP). After surgery, all patients underwent seriate chest x-ray and ultrasound to record thoracic complications. Statistical analysis included uni- and multivariable logistic regression model (proportional odds model). RESULTS: Three hundred seventy-one patients were screened and 88 patients were enrolled: 44 in arm A and B, respectively. No statistically significant differences for intra-operative (p = 0.291) and any grade of post-operative complication (p = 0.072) were detected, while 6.8% of patients in arm A and 22.7% in arm B experienced severe respiratory symptoms (p = 0.035); 18.2% of patients in arm A had a moderate/large pleural effusion versus 65.9% in arm B (p < 0.0001). At multivariable analysis, results confirmed that the NTP-group had a higher risk to receive post-operative thoracostomy tube placement due to pleural effusion than the TP-group (odds ratio [95% Confidence Interval] = 14.5 [3.7-57.4]). CONCLUSIONS: Thoracostomy intra-operative tube placement after diaphragmatic resection is effective to prevent post-operative thoracic complications. The extension of resection does not influence outcomes and the risk of post-operative thoracentesis or TP remain elevated.

PURPOSE: Chemoradiation (CT/RT) followed by radical surgery (RS) may play a role in locally advanced cervical cancer (LACC) patients with suboptimal response to CT/RT or in low-income countries with limited access to radiotherapy. Our aim is to evaluate oncological and surgical outcomes of minimally invasive radical surgery (MI-RS) compared with open radical surgery (O-RS). PATIENTS AND METHODS: Data for stage IB2-IVA cervical cancer patients managed by CT/RT and RS were retrospectively analyzed. RESULTS: Beginning with 686 patients, propensity score matching resulted in 462 cases (231 per group), balanced for FIGO stage, lymph node status, histotype, tumor grade, and clinical response to CT/RT. The 5-year disease-free survival (DFS) was 73.7% in the O-RS patients and 73.0% in the MI-RS patients (HR 1.034, 95% CI 0.708-1.512, p = 0.861). The 5-year locoregional recurrence rate was 12.5% (O-RS) versus 15.2% (MI-RS) (HR 1.174, 95% CI 0.656-2.104, p = 0.588). The 5-year disease-specific survival (DSS) was 80.4% in O-RS patients and 85.3% in the MI-RS group (HR 0.731, 95% CI 0.438-1.220, p = 0.228). Estimated blood loss was lower in the MI-RS group (p < 0.001), as was length of hospital stay (p < 0.001). Early postoperative complications occurred in 77 patients (33.3%) in the O-RS group versus 88 patients (38.1%) in the MI-RS group (p = 0.331). Fifty-six (24.2%) patients experienced late postoperative complications in the O-RS group, versus 61 patients (26.4%) in the MI-RS group (p = 0.668). CONCLUSION: MI-RS and O-RS are associated with similar rates of recurrence and death in LACC patients managed by surgery after CT/RT. No difference in early or late complications was reported.

PURPOSE: To analyze the follow-up results of patients suffering from symptomatic early-stage endometriosis after a consistent laparoscopic peritoneal stripping of the altered peritoneum (peritoneal endometriosis and surrounding inflamed tissue) was performed. This type of endometriosis is resistant to medical therapy and/or impairs fertility. METHODS: Using our prospectively maintained database, we were able to identify all symptomatic women with the suspicion of only peritoneal endometriosis who underwent laparoscopy at our endometriosis center over a period of 5 years. All procedures were carried out in a standardized fashion by one single surgeon, who is highly experienced in minimal invasive surgery, and included a suspended hormonal pretreatment for 2 months. Postoperative outcomes including complications, fertility and recurrence rates were analysed. RESULTS: Laparoscopic peritonectomy was performed on 94 women. Follow-up data were available in 87% of these cases. At the time of surgery, almost all patients tested showed signs of stage I or II endometriosis (44.7 and 48.9%, respectively). More than three-quarters of the women reported pain relief, inter alia, due to the post-surgical hormonal therapy. About one-third of the patients wanted to have children after the procedure. 62% of them became pregnant and the majority did so without the need for assisted reproductive therapy. In seven women a re-operation was performed. CONCLUSION: According to our data, a consistent excision of altered peritoneum followed by adjuvant hormonal therapy and multimodal concepts results in better outcomes for the patient, particularly in regards to pregnancy and recurrence rates.

OBJECTIVE: To determine the factors related with diverting ileostomy performance after colorectal resection and anastomosis, in advanced ovarian cancer cytoreductive surgery. METHODS: We have previously demonstrated the risk factors associated with anastomotic leak after colorectal anastomosis: Advanced age at surgery, low serum albumin level, additional bowel resections, manual anastomosis and distance of the anastomosis from the anal verge. However, use of diverting ileostomy is strongly variable and depends on individual surgeon preferences and training. Eight hospitals participated in this retrospective study. Data of 695 patients operated for ovarian cancer with primary colorectal anastomosis were included (January 2010-June 2018). Fourteen pre-/intraoperatively defined variables were identified and analysed as justification factors for use of diverting ileostomy. RESULTS: The rate of diverting ileostomy in the entire cohort was 19.13% (133/695; range within individual centers 4.6-24.32%). Previous treatment with bevacizumab [OR 2.8 (1.3-6.1); p=0.01]; additional bowel resections [OR 3.0 (1.8-5.1); p<0.001]; extended operating time [OR 1.005 (1.003-1.006); p<0.001] and intra-operative red blood transfusion [OR 2.7 (1.4-5.3); p<0.001] were found to be independently associated with diverting ileostomy performance. Assuming a 7% AL rate cut-off, up to 51.8% of DI presented an AL risk below 7% and might have been spared. CONCLUSIONS: The risk factors that drive the gynecologic oncology surgeons to perform a diverting ileostomy, seem to differ from the actual risk factors that we have identified to be associated with postoperative anastomotic leak. Broader awareness of the risk factors that contribute to a higher perioperative risk profile, will facilitate a better risk stratification process and possibly avoid unnecessary stoma formation in ovarian cancer patients.

OBJECTIVE: To determine pre-/intraoperative risk factors for anastomotic leak after modified posterior pelvic exenteration (MPE) or colorectal resection in ovarian cancer and to create a practical instrument for predicting anastomotic leak risk. BACKGROUND: In advanced ovarian cancer surgery, there is rather limited published evidence, drawn from a small sample, providing information about risk factors for anastomotic leak. METHODS: Eight hospitals participated in this retrospective study. Data on 695 patients operated for ovarian cancer with primary anastomosis were included (January 2010-June 2018). Twelve pre-/intraoperative variables were analysed as potential independent risk factors for anastomotic leak. A predictive model was created to stablish the risk of anastomotic leak for a given patient. RESULTS: The anastomotic leak rate was 6.6% (46/695; range 1.7%-12.5%). A total of 457 patients were included in the final multivariate analysis. The following variables were found to be independently associated with anastomotic leakage: age at surgery (OR 1.046, 95% CI 1.013-1.080, pâ¯=â¯0.005), serum albumin level (OR 0.621, 95% CI 0.407-0.948, pâ¯=â¯0.027), one or more additional small bowel resections (OR 3.544, 95% CI 1.228-10.23, pâ¯=â¯0.019), manual anastomosis (OR 8.356, 95% CI 1.777-39.301, pâ¯=â¯0.007) and distance of the anastomosis from the anal verge (OR 0.839, 95% CI 0.726-0.971, pâ¯=â¯0.018). CONCLUSIONS: Due to the low incidence of AL in ovarian cancer patients, a restrictive stoma policy based on the presence of risk factors should be the actual recommendation. Hand-sewn anastomosis should be avoided.

PURPOSE: To evaluate the practice patterns among centers and physicians worldwide regarding sentinel lymph node biopsies (SLNB) in cervical cancer (CC) patients. METHOD: A validated 35-item questionnaire regarding SLNB in CC supported by the Gynecologic Cancer Intergroup (GCIG), and sponsored by the North-Eastern German Society of Gynaecologic-Oncology (NOGGO) was sent to all major gynecological cancer societies across the globe for further distribution from October 2015 and continued for a period of 7 months. RESULTS: One hundred and sixty-one institutions from around the world participated. One hundred and six (66%) of the participants were from university centers and 111 (69%) were gynecologic oncologists. One hundred and fifty-two (97%) performed lymphadenectomy (LNE) and 147 (94%) did so systematically; 97 (60%) used SLNB, due to lower morbidity (73%), reliability (55%) and time-saving (27%). In cases of positive SLNB (pN+), 39% of respondents stopped the operation and sent the patient for chemoradiation (CRT), 45% completed pelvic and paraaortic LNE, whereas 26% went on to perform a radical hysterectomy (RH) and systematic pelvic and paraaortic LNE. In case of negative SLNB (pN0), 39% of institutions still performed a systematic pelvic and paraaortic LNE. CONCLUSION: In this survey worldwide, SLNB adoption is an encouraging 60%, yet ample differences exist regarding strategy, and to a lower extent the techniques used. Lack of experience is the most common reason SLNB is not performed. Efforts to increase surgical education on SLNB technique and multicenter prospective trials providing evidence-based guidelines are warranted.

STUDY HYPOTHESIS: Loss of protein BAF250a (ARID1A) expression is present in women with rectovaginal deep-infiltrating endometriosis (DIE) and endometriosis affecting the pelvic sentinel lymph nodes (PSLN). STUDY FINDING: Partial loss of protein BAF250a was found in some of our patient samples, comprising all endometriosis entities, including rectovaginal DIE and endometriosis affecting the PSLN. WHAT IS KNOWN ALREADY: Loss of BAF250a (BRG-associated factor 250a)/ARIDIA (AT-rich interactive domain 1A) protein expression was identified among endometriosis-associated ovarian carcinomas and ovarian endometriosis, and this phenomenon was described as a possible early event in the transformation of endometriosis into cancer. DIE affecting the bowel/rectovaginal site is the most aggressive presentation of endometriosis and its 'risk' of malignant transformation has not been studied so far. STUDY DESIGN, SAMPLES/MATERIALS, METHODS: We evaluated the immunohistochemical expression of BAF250a protein in 70 samples from patients enrolled in this study who were surgically treated at a tertiary center, university Hospital. The samples submitted to investigation were from rectovaginal DIE (n= 25/30), endometriosis affecting the PSLN (n= 5/7), ovarian endometriosis (n= 20/20) and endometrium from patients without endometriosis used as controls (n= 20/20). MAIN RESULTS AND THE ROLE OF CHANCE: Partial loss (i.e. in one tissue section some cells stained positive for BAF250a while other cells, usually an adjacent group, were negative) of BAF250a protein was identified in 36% (9/25) of rectovaginal DIE samples, 40% (2/5) of endometriosis lesions involving the PSLN, 30% (6/20) of endometriomas, and also in 25% (5/20) of endometrium from controls. We found no statistical correlation between occurrence of partial loss of BAF250a protein and the use or not of hormone medications (P = 0.106), cycle phase (P = 0.917) and stage of disease (P = 0.717). LIMITATIONS, REASONS FOR CAUTION: We only found partial loss of BAF250a protein expression, and in a small population of women, with relatively high frequency in all benign tissues assessed in the present analysis. Therefore, this finding alone should not be correlated directly with the risk of malignant transformation in these lesions. WIDER IMPLICATIONS OF THE FINDINGS: The occurrence of partial loss of BAF250a protein expression in women with rectovaginal DIE and endometriosis affecting the PSLN is described for the first time. The value of this finding as a predictor of malignant transformation in endometriosis must still be clarified and further studied in association with other molecular events, such as PTEN (phosphatase and tensin homolog) deletion and PIK3CA (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha) mutation. We might then be able to identify in the future which patients with endometriosis are at higher risk of cancer. STUDY FUNDING AND COMPETING INTERESTS: This study was supported by an internal Charité grant to the Endometriosis Research Center and the authors declare no conflicts of interest.

OBJECTIVES: Recurrence of disease represents a clinical challenge in cervical cancer patients, especially when all available treatment modalities have been used in the primary setting. The aim of this study was to analyze the patterns of recurrence and their association with clinical outcome in locally advanced cervical cancer (LACC) patients submitted to primary chemoradiation (CTRT) followed by radical surgery (RS). METHODS: This study was conducted on 364 LACC patients treated with CTRT plus RS since January 1996 to July 2012. For each relapse, information on date of clinical/pathological recurrence, and pattern of disease presentation were retrieved. Post-relapse survival (PRS) was recorded from the date of recurrence to the date of death for disease or last seen. Survival probabilities were compared by the log rank test. Cox's regression model with stepwise variable selection was used for multivariate prognostic analysis for PRS. RESULTS: Within a median follow-up of 42months, 75 recurrences (20.6%) and 54 disease-associated deaths (14.8%) were recorded. By analysing the pattern of relapse, most of the recurrences were outside the irradiated field (n=43, 57.3%) and the most frequently observed site was visceral (n=16, 21.3%). Among the parameters of the recurrence associated with PRS including the pattern of recurrence, the size of recurrence, SCC-Ag serum levels at recurrence, and secondary radical surgery, only the last one retained an independent predictive role in reducing the risk of death (p=0.037). CONCLUSIONS: The feasibility of secondary radical resection positively impacts on PRS of LACC patients submitted to multimodality primary treatments.

OBJECTIVE: To analyze the feasibility of total mesometrial resection by laparoscopy (L-TMMR) in a multicentric series of early stage cervical cancer. METHOD: We prospectively evaluated a consecutive series of cervical cancer patients with pre-operative FIGO stages IA2-IB1 at the Catholic University in Rome and in Campobasso and the Charitè University in Berlin. All cases were assessed at pre-operative MRI scan and clinically confirmed by investigation under anesthesia, adhering strictly to the FIGO criteria. The surgical and post-surgical data were collected. RESULTS: 104 women with cervical cancer were admitted between July 2013 and August 2014 and among them 71 patients with pre-operative FIGO stages IA2-IB1 were treated with L-TMMR. One laparotomic conversion was registered. The median operative time was 260min (120-670min), estimated blood loss was 100cm(3) (25-900cm(3)), and the median length of hospital stay was 6days (2-26days). We observed 8 intra-operative complications including a vascular injury of the left internal iliac vein that caused conversion, 6 vesical injuries and 1 ureteral injury managed laparoscopically. Two vescico-vaginal fistula and one hemoperitoneum were observed as major post-operative complications (4.2%). CONCLUSION: L-TMMR can be safely performed in selected cervical cancer patients. Further larger prospective trials are needed to evaluate the oncological outcome of patients undergoing this surgical procedure.

OBJECTIVE: To develop an updated laparoscopy-based model to predict incomplete cytoreduction (RT>0) in advanced epithelial ovarian cancer (AEOC), after the introduction of upper abdominal surgery (UAS). PATIENTS AND METHODS: The presence of omental cake, peritoneal extensive carcinomatosis, diaphragmatic confluent carcinomatosis, bowel infiltration, stomach and/or spleen and/or lesser omentum infiltration, and superficial liver metastases was evaluated by staging laparoscopy (S-LPS) in a consecutive series of 234 women with newly diagnosed AEOC, receiving laparotomic PDS after S-LPS. Parameters showing a specificity≥75%, PPV≥50%, and NPV≥50% received 1 point score, with an additional one point in the presence of an accuracy of ≥60% in predicting incomplete cytoreduction. The overall discriminating performance of the LPS-PI was finally estimated by ROC curve analysis. RESULTS: No-gross residual disease at PDS was achieved in 135 cases (57.5%). Among them, UAS was required in 72 cases (53.3%) for a total of 112 procedures, and around 25% of these patients received bowel resection, excluding recto-sigmoid resection. We observed a very high overall agreement between S-LPS and laparotomic findings, which ranged from 74.7% for omental cake to 94.8% for stomach infiltration. At a LPS-PIV≥10 the chance of achieving complete PDS was 0, and the risk of unnecessary laparotomy was 33.2%. Discriminating performance of LPS-PI was very high (AUC=0.885). CONCLUSIONS: S-LPS is confirmed as an accurate tool in the prediction of complete PDS in women with AEOC. The updated LPS-PI showed improved discriminating performance, with a lower rate of inappropriate laparotomic explorations at the established cut-off value of 10.

OBJECTIVE: To analyze the feasibility of laparoscopic/robotic secondary cytoreductive surgery and hyperthermic intraperitoneal intra-operative chemotherapy (SCS+HIPEC) in a retrospective series of isolated platinum sensitive recurrent ovarian cancer. METHODS: We retrospectively evaluated a consecutive series of ovarian cancer patients with isolated platinum sensitive relapse. Isolated relapse was defined as the presence of a single nodule, in a single anatomic site. In all cases the presence of isolated relapse was assessed at pre-operative FDG-PET/CT scan, and confirmed with staging laparoscopy performed immediately before SCS+HIPEC. RESULTS: 84 women with platinum sensitive relapse received SCS+HIPEC during a 4-year period. Among them, 10 cases (11.9%) showed isolated relapse and were treated with laparoscopic/robotic SCS+HIPEC. In all cases complete debulking was achieved. In HIPEC treatment, 9 women received cisplatin at 75 mg/m(2), and the remaining patient oxaliplatin 460 mg/m(2). In 7 patients SCS was performed through the laparoscopic route, and in 3 cases with a robotic approach. The median operative time from skin incision to the end of cytoreductive surgery was 122 min (95-140), estimated blood loss was 50 cm(3) (50-100), and the median length of hospital stay was 4 days (3-7). The interval from surgery to adjuvant chemotherapy was 21 days (19-32). No grade 3/4 surgical, metabolic, or hematologic complications occurred. In all cases post-operative FDG-PET/CT scan was negative, and after a median time of 10 months (6-37) from SCS+HIPEC no secondary recurrence was observed. CONCLUSIONS: Minimally invasive SCS+HIPEC can be safely performed in selected ovarian cancer patients with platinum sensitive isolated relapse.

OBJECTIVE: The aim of this study is to analyze the safety, adequacy, perioperative and survival figures in a large series of laparoscopic staging of patients with apparent early stage ovarian malignancies (ESOM). PATIENTS AND METHODS: Retrospective data from seven gynecologic oncology service databases were searched for ESOM patients undergoing immediate laparoscopic staging or delayed laparoscopic staging after an incidental diagnosis of ESOM. Between May 2000 and February 2014, 300 patients were selected: 150 had been submitted to immediate laparoscopic staging (Group 1), while 150 had undergone delayed laparoscopic staging (Group 2) of ESOM. All surgical, pathologic, and oncologic outcome data were analyzed in each group and a comparison between the two was carried out. RESULTS: Longer operative time, higher blood loss, more frequently spillage/rupture of ovarian capsule and conversion to laparotomy occurred in Group 1. No significant differences of post-operative complications were observed between the two groups. Histological data revealed more frequently serous tumors (0.06), Grade 3 (p=0.0007) and final up-staging (p=0.001) in Group 1. Recurrence and death of disease were documented in 25 (8.3%), and 10 patients (3.3%%), respectively. The 3-year disease free survival (DFS) and overall survival (OS) rates were 85.1%, and 93.6%, respectively in the whole series. There was no difference between Group 1 and Group 2 in terms of DFS (p value=0.39) and OS (p value=0.27). CONCLUSION: In this very large multi-institutional study, it appears that patients with apparent ESOM can safely undergo laparoscopic surgical management.

Clear cell adenocarcinoma (CCAC) of the uterine cervix is a rare variant of cervical adenocarcinoma accounting for approximately 4-9% of this disease. Given the rarity of this pathological entity, the optimal treatment management is far from being defined. Earlier evidence suggested that the prognosis of patients bearing cervical CCAC is worse than with other histotypes, thus making the investigation of multimodal treatment strategies clinically worthwhile. Herein, we report the first case of locally advanced, large size cervical CCAC in a young woman who was triaged to concomitant chemoradiotherapy followed by radical surgery and experienced a pathologically assessed optimal response to this multimodal approach.

Pelvic exenteration is a radical procedure representing a salvage option in patients with recurrent or persistent gynaecological malignancies. It can be performed with an open or minimally invasive approach. Different studies have demonstrated optimal peri-operative outcomes of minimally invasive pelvic exenteration with no survival difference when compared with an open approach. In this article, we discuss the importance and the challenge of patient selection for pelvic exenteration and more specifically for minimally invasive pelvic exenteration.
RESUMO
OBJECTIVE: Several studies have shown higher pregnancy rates and better perinatal outcomes with frozen embryo transfers than with fresh techniques, with better results in patients with polycystic ovary syndrome (PCOS) but with a higher rate of pregnancy complications such as preeclampsia. This retrospective cohort study aims to compare the cumulative live birth rates, maternal and neonatal complications of fresh embryo transfers (ET) and frozen-embryo transfers (FET) in infertile women who underwent assisted reproduction techniques (ART) at the Azienda Ospedaliera Ospedali Riuniti (AOOR) Villa Sofia Cervello, Palermo, Italy. In addition, the authors have focused on the legislative and ethical complexities which such a procedure entails. PATIENTS AND METHODS: Out of 475 women undergoing in vitro fertilization programs from January 2017 to January 2021, 128 were enrolled; 70 patients underwent ET, and 58 patients FET. The main outcome measure was live birth rates. Secondary outcomes were clinical pregnancy, ongoing pregnancy, pregnancy loss, low birth weight (LBW), ectopic pregnancy, and obstetrical and perinatal complications. RESULTS: The cumulative live birth rates were similar between the fresh transfer (95.7%) and frozen transfer (93.1%). Biochemical pregnancy rates, clinical pregnancy, ongoing pregnancy, and pregnancy loss were similar between the groups. CONCLUSIONS: Obstetrical outcomes were not statistically different between the two groups; a higher preterm delivery rate was reported in the FET group. ET birth weights were notably lower for singletons compared to the freeze-all strategy. ET patients also had higher LBW rates, with a 2.5-fold higher rate compared to FET. No significant differences were found in cumulative live birth rates between ET and FET, which is consistent with earlier studies. FET protocols are linked to higher neonatal birth weight and lower risk of LBW than fresh ET. The ethical and legal quandaries inherent in such techniques, as technology moves on and outpaces current legislative frameworks, cannot be discounted.

Laparoscopic surgery underwent great improvements during the last few years. This review aims to compare the performance of Trainee Surgeons using 2D versus 3D/4 K laparoscopy. A systematic review of the literature was done on Pubmed, Embase, Cochrane's Library and Scopus. The following words and key phrases have been searched: "Two-dimensional vision", "Three-dimensional vision", "2D and 3D laparoscopy", "Trainee surgeons". This systematic review was reported according to the PRISMA statement 2020. PROSPERO registration No. CRD42022328045. Twenty-two randomized controlled trials (RCTs) and two observational studies were included in the systematic review. Two trials were carried out in a clinical setting, and twenty-two trials were performed in a simulated setting. In studies involving the use of a box trainer, the number of errors in the 2D laparoscopic group was significantly higher than in the 3D laparoscopic group during the performance of FLS skill tasks: peg transfer (MD: -0.82; 95% CI - 1.17 to - 0.47; p < 0.00001), cutting (MD: - 1.09; 95% CI - 1.50 to - 0.69 p < 0.00001), suturing (MD: - 0.48; 95% CI - 0.83 to - 0.13 p = 0.007), However, in clinical studies, there was no significant difference in the time taken for laparoscopic total hysterectomy (MD: 8.71; 95% CI - 13.55 to 30.98; p = 0.44) and vaginal cuff closure (MD: 2.00; 95% CI - 0.72 to - 4.72; p = 0.15) between 2D group and 3D group. 3D laparoscopy facilitates learning for novice surgeons and shows improvements in their laparoscopic performance.

Radical hysterectomy with pelvic lymphadenectomy is the standard surgical treatment for patients with early stage cervical cancer. The majority of radical hysterectomies are performed with the open technique. However, laparoscopic, combined laparoscopic and vaginal, and robotic-assisted approaches may also be used. Compared with the abdominal radical hysterectomy (ARH), laparoscopic techniques are associated with less blood loss, shorter hospital stay, better cosmesis, and faster recovery. A further breakthrough in laparoscopic technique can only be made if safety and oncological clearance are comparable with ARH. We describe the technique and results of laparoscopic assisted radical vaginal hysterectomy and the transition to vaginal assisted laparoscopic radical hysterectomy.

BACKGROUND: Uterine leiomyomas are the most common benign tumours in women, which arise from smooth muscle cells of the uterine myometrium and usually are multicentric. In spite of their frequency pathogenesis is widely unknown, mainly due to the absence of a suitable model system. We describe the systematic optimization of culturing leiomyoma tissue explants in an economical and effective ex vivo system. METHODS: Different concentrations of oxygen, different media, sera, hormones, and growth factor supplements were tested. Immunohistochemical stainings with antibodies against hormone receptors as well as specifying proliferation and apoptotic indices and real-time PCR were performed. RESULTS: Main parameters for culturing myoma tissue explants were tested for finding an optimal protocol. Standard medium D-MEM-F12 in combination with the use of horse serum in a reduced concentration of 1% turned out to be optimal for these tissue cultures as well as the addition of estradiol and epidermal growth factor EGF to media. Reduced oxygen content in the incubator air showed no positive effect. CONCLUSIONS: For culturing tissue explants of uterine leiomyoma several conditions were optimized. The established tissue culture model allows examining the effects of known and potential therapeutic substances and the influence of immune competent cells in the process of tumour formation to find new targets for medical treatment.

Menopausal transition entails a progressive decrease in hormone production by the ovaries that lead to important physical and psychological changes that could significantly affect quality of life. Hormone replacement therapy (HRT) administered from the onset of menopausal symptoms usually improves quality of life and life expectancy. Nevertheless, it is not risk-free. Ovarian tissue cryopreservation (OTC) has been investigated as a potential new strategy for delaying menopause and/or to avoid HRT. This review analyzes the critical points of HRT to assess whether OTC and subsequent reimplantation can affect postmenopausal management. We assessed available randomized clinical trials in PubMed, Cochrane Library, ISI web of science, and Scopus from August 2021 to November 2022, including studies and trials evaluating the efficacy of OTC in both cancer and menopausal patients, the efficacy of freezing techniques and the possible clinical scenarios that OTC can open, even from the standpoint of legal and ethical issues arising as such innovative techniques become mainstream. Lower duration of the graft and efficacy on estrogen secretions at a physiological and safer concentration of estrogen than conventional HRT based on hormonal supplements. OTC can reportedly trigger estrogen secretions at a lower and safer physiological concentration than conventional HRT. OTC and subsequent reimplantation remain a valid fertility-sparing approach in patients undergoing gonadotoxic treatments. Further studies are needed to better evaluate its safety and efficacy within postmenopausal therapy management and in order to lay out widely shared and evidence-based guidelines and best practices and perform such novel and innovative techniques in a legally and ethically safe fashion, in the best interest of patients and healthcare professionals.

PURPOSE: Despite the establishment of radical surgery for therapy of cervical cancer, data on quality of life and patient-reported outcomes are scarce. The aim of this retrospective cohort study was to evaluate bladder, bowel and sexual function in women who underwent minimally invasive surgery for early-stage cervical cancer. METHODS: From 2007-2013, 261 women underwent laparoscopically assisted radical vaginal hysterectomy (LARVH = 45), vaginally assisted laparoscopic or robotic radical hysterectomy (VALRRH = 61) or laparoscopic total mesometrial resection (TMMR = 25) and 131 of them completed the validated German version of the Australian Pelvic Floor Questionnaire (PFQ). Results were compared with controls recruited from gynecological clinics (n = 24) and with urogynecological patients (n = 63). RESULTS: Groups were similar regarding age, BMI and parity. The TMMR group had significantly shorter median follow-up (16 months versus 70 and 36 months). Postoperatively, deterioration of bladder function was reported by 70%, 57% and 44% in the LARVH, VARRVH and TMMR groups, respectively (p = 0.734). Bowel function was significantly worse after TMMR with a higher deterioration rate in 72 versus 43% (LARVH) and 47% (VARRVH) with a correspondingly higher bowel dysfunction score of 2.9 versus 1.5 and 1.8, respectively and 1.8 in urogynaecological patients. Sexual dysfunction was common in all surgical groups. 38% considered their vagina too short which was significantly associated with deep dyspareunia. Compared with controls, surgical groups had significantly increased PFQ scores. CONCLUSION: Pelvic floor dysfunction commonly deteriorates and negatively impacts on quality of life after minimally invasive radical hysterectomy, especially bowel function after TMMR. Pelvic floor symptoms should routinely be addressed pre- and postoperatively.
