Introduction: Sentinel lymph node (SLN) biopsy algorithm has been routinely applied in all endometrial endometrioid tumors, however, no studies analyzed the feasibility of SLN mapping in endometrioid variants (EV), which included villoglandular, secretory, ciliated cell, mucinous, and squamous differentiation. This study aimed to demonstrate the feasibility of SLN biopsy in EV of EC. Materials and methods: All patients undergoing minimally invasive surgical treatment for early-stage EC were included in the study. Patients were divided into 2 study groups: Group 1 which included patients with EV, and Group 2 which included patients with typical endometrioid histology. A propensity match analysis was performed according to age (≥65 years vs. no), BMI (≥30 kg/m2 vs. no), and LVSI (present vs. absent). Results: After a 1:5 propensity-matched analysis, a total of 458 patients were identified (Group 1 n = 77, Group 2 n = 381). Overall detection rate was not statistically significant between the EV and the typical endometrioid group (94.8% vs. 92.4%, p = 0.319). Furthermore, neither bilateral nor unilateral detection rate was different between the two groups (70.1% vs. 74.8%, p = 0.267, and 23.4% vs. 17.8%, p = 0.120). BMI ≥30 kg/m2 was the only factor influencing SLN failure (p = 0.013). SLN technique showed excellent sensitivity in both the EV (100% sensitivity, p < 0.001) and the typical endometrioid unit (93.8% sensitivity, p < 0.001). Conclusion: SLN research/detection for EV of endometrial cancer is a feasible and highly sensitive technique. Obesity was confirmed to be a risk factor for SLN failure.

Objective: Atypical endometrial hyperplasia (AH) is the neoplastic precursor more often associated with endometrial cancer (EC). Nowadays, 25–50% of patients subjected to hysterectomy for preoperative AH are diagnosed with EC at the final pathological analysis. Furthermore, there is no consensus on which preoperative AH patients would benefit from sentinel lymph node mapping. This study aimed to evaluate nodal assessment and preoperative cancer risk factors in preoperative AH patients undergoing nodal surgical staging. Methods: Patients undergoing surgical treatment for AH were retrospectively included in the analysis. Patients were divided into two groups (AH and EC groups) based on the final surgical pathology. The ESGO/ESTRO/ESP risk classification was used for EC cases. Design: This was a retrospective study. Results: Of the 207 AH patients treated, 152 cases met the inclusion criteria. Among preoperative AH patients with final EC diagnosis, 39 patients were in the low-risk group (25.7%), 8 in the intermediate-risk group (5.3%), 4 in high-intermediate (2.6%), and 3 patients were allocated in the high-risk group (2.0%). Fifty-four total patients underwent nodal surgical staging. Only one nodal micrometastasis (0.7%) was found at ultrastaging. Multivariate analysis showed abnormal uterine bleeding (AUB) (p = 0.01), hypertension (p < 0.01), and endometrial thickness ≥20 mm (p = 0.02) statistically more represented in patients with EC at final surgical analysis. EC risk was 2.9 (95% CI: 1.29–6.48) in AUB, 2.7 (95% CI: 1.06–6.92) in hypertension, and 3.1 (95% CI: 1.19–7.97) in endometrial thickness ≥20 mm cases. Limitations: The present study has limitations inherent in its retrospective nature. Conclusion: The overall risk of nodal metastases in preoperative AH patients was low. Conversely, 9.9% of the preoperative AH patients belonged to the intermediate or high-risk group for EC at the final histological examination. Preoperative cancer risk factors would identify AH patients for whom nodal staging could be suggested.

Dissolution Dynamic Nuclear Polarization (dDNP) is the most versatile hyperpolarization technique to enhance NMR sensitivity in the liquid state. The unprecedented signal enhancement is the key for a large range of applications spanning from fast chemical reaction monitoring to metabolism investigation in real time. Unfortunately, this exceptional time resolution does not come without a price. Low throughput is one of dDNP main shortcomings. Especially for clinical and preclinical applications, where direct 13C nuclei polarization is usually pursued, it takes hours to generate one single hyperpolarized (HP) sample. Therefore, being able to hyperpolarize more samples at once represents a clear advantage and can expand the range and complexity of the applications. Some clinical and preclinical systems are equipped with a multi-sample option. Nevertheless, the solid-state NMR detection is far from optimal, not being sample selective or requiring the displacement of the sample to acquire and monitor its signal. In this work, we present the design and performance of a highly versatile and customizable dDNP cryogenic probe, herein adapted to a 5 T “wet” preclinical polarizer, that can not only accommodate up to three Custom Fluid Paths (CFPs), but it is also capable of monitoring the solid-state dynamics of each sample separately, thanks to dedicated pseudo-Alderman-Grant coils and multi-nuclei parallel Nuclear Magnetic Resonance (NMR) acquisition on three distinct channels. Within 30 min, the system was able to dispense three HP solutions with high repeatability across the channels (30.0 ± 1.2% carbon polarization for [1-13C]pyruvic acid doped with trityl radical). Moreover, we tested multi-nucleus NMR capability by polarizing and monitoring simultaneously 13C, 1H and 129Xe. Finally, we implemented [1-13C]lactate/[1-13C]pyruvate polarization and back-to-back dissolution and injection in a healthy mouse model to perform multiple-substrate HP Magnetic Resonance Spectroscopy (MRS) at 14.1 T.

ObjectiveEndometrial cancer is the most common gynecologic neoplasm. To date, international guidelines recommend sentinel lymph node biopsy for low-risk neoplasms, while systematic lymphadenectomy is still considered for high-risk cases. This study aimed to compare the long-term survival of high-risk patients who were submitted to sentinel lymph node biopsy alone versus systematic pelvic lymphadenectomy.MethodsPatients with high-risk endometrial cancer according to the 2021 European Society of Gynaecological Oncology/European Society for Radiotherapy and Oncology/European Society of Pathology risk classification were retrospectively analyzed. The primary aim of the study was to compare the long-term overall survival and disease-free survival of high-risk endometrial cancer patients undergoing sentinel lymph node biopsy versus systematic lymphadenectomy. A supplementary post-hoc survival analysis of cases with nodal metastasis was performed to compare sentinel lymph node and lymphadenectomy survival outcomes in this subset of patients.ResultsThe study enrolled 237 patients with histologically proven high-risk endometrial cancer. Patients were followed up for a median of 31 months (IQR 18–40). During the follow-up, 38 (16.0%) patients had a recurrence, and 19 (8.0%) patients died. Disease-free survival (85.2% vs 82.8%; p=0.74) and overall survival (91.3% vs 92.6%; p=0.62) were not different between the sentinel lymph node alone and lymphadenectomy groups. Furthermore, neither overall survival (96.1% vs 91.4%; p=0.43) nor disease-free survival (83.7% vs 76.4%; p=0.46) were different among sentinel lymph node alone and lymphadenectomy groups in patients with nodal metastasis.ConclusionsSentinel lymph node mapping alone in high-risk endometrial cancer appears to be an oncologically safe technique over a long observational time. Systematic lymphadenectomy in this population does not offer a survival advantage.

Background and Objectives: Minimally invasive surgery (MIS) has recently increased its application in the treatment of gynecological malignancies. Despite technological and surgical advances, urologic complications (UC) are still the main concern in gynecology surgery. Current literature reports a wide range of urinary tract injuries, and consistent scientific evidence is still lacking or dated. This study aims to report a large single-center experience of urinary complications during laparoscopic hysterectomy for gynecologic oncologic disease. Materials and Methods: All patients who underwent laparoscopic hysterectomy for gynecologic malignancy at the Department of Medicine and Surgery of the University Hospital of Parma from 2017 to 2021 were retrospectively included. Women with endometrial cancer, cervical cancer, ovarian cancer, uterine sarcoma, or borderline ovarian tumors were included. Patients undergoing robotic surgery with incomplete anatomopathological data or patients lost during follow-up were excluded from the analysis. Intraoperative and postoperative UC were analyzed and ranked according to the Clavien-Dindo classification. Results: Two hundred-sixty patients were included in the study: 180 endometrial cancer, 18 cervical cancer, nine ovarian cancer, two uterine sarcomas, and 60 borderline ovarian tumors. Nine (3.5%) UCs were reported (five intraoperative and four postoperative complications). No anamnestic variables showed a statistical correlation with the surgical complication in the univariable analyses. C1 radical hysterectomy, a higher FIGO stage, and postoperative adjuvant treatment (p-value = 0.001, p-value = 0.046, and p-value = 0.046, respectively) were independent risk factors associated with the occurrence of UC. Conclusions: The urological complication rates in patients with oncological disease are relatively rare events in the expert hands of dedicated surgeons. Radical hysterectomy, FIGO stage, and adjuvant treatment are independent factors associated with urinary complications.

Cervical cancer is the fourth most common neoplasm in women. In locally advanced cervical cancers, the international guidelines recommend nodal aortic assessment. Two techniques have been described to perform laparoscopic aortic lymphadenectomy: transperitoneal laparoscopic lymphadenectomy (TLL) and extraperitoneal laparoscopic lymphadenectomy (ELL). This meta-analysis aims to compare the surgical outcomes of TLL and ELL for staging purposes. The systematic review was carried out in agreement with the preferred reporting items for systematic reviews and meta-analyses statement (PRISMA). Two hundred and twenty studies were analyzed, and 19 studies were included in the review (7 for TLL and 12 for ELL group). 1112 patients were included in the analysis: 390 patients were included in group 1 and 722 patients in group 2.38 patients (9.7%) in the TLL group and 69 (9.5%) patients in the ELL group developed major complications. The analysis of all complications (intraoperative and postoperative) rate through pooled analysis did not show a significant difference between the two groups (p = 0.979), although a significantly higher intraoperative complication rate (p = 0.018) occurred in the TLL group compared to ELL. No significant differences were found between groups for BMI (p = 0.659), estimated blood loss (p = 0.889), length of stay (p = 0.932), intraoperative time (p = 0.932), conversion to laparotomy rate (p = 0.404), number of lymph node excised (p = 0.461) and postoperative complication (p = 0.291). TLL approach shows a higher rate of intraoperative complications, while no significant difference was found between the two techniques when postoperative complications were analyzed.

Introduction Endometrial cancer (EC) is the most common gynecological cancer. Sentinel lymph node (SLN) technique has been adopted worldwide and showed lower morbidity and superimposable survival outcomes than the systematic lymphadenectomy (LND). Although these encouraging results, no meta-analyzes were performed on surgical complications during SLN research among patients undergoing laparoscopic (L) versus robotic surgery (R). The present review aims to report surgical complications during laparoscopic versus robotic SLN technique. Methods The Preferred Reporting Items for Systematic reviews and Meta-Analyzes (PRISMA) and the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines have been followed for the present meta-analysis. Results Six studies, including 769 participants, were included. L-LND resulted in a significantly higher risk of operative complications relative to L-SLN (RR 2.10 [95% CI 1.37 to 3.21]). The risk of complications was comparable between R-SLN and L-SLN (RR 2.32 [95% CI 0.04–121.02]) and between R-LND and L-LND (RR 2.17 [95% CI 0.04–126.69]). According to the SUCRA analysis, L-SLN and R-SLN had the highest chances of being ranked first among proposed surgical procedures (SUCRA 48.9% and 28.4% respectively). Conclusions Our study reported a lower surgical complications rate in patients undergoing L-SLN technique compared to L-LND. A lower rate of surgical complications was also reported for the R-SLN technique compared to the R-LND. Both laparoscopic and robotic SLN surgical techniques were found to be safe surgical procedures.

Introduction Obesity is a known independent risk factor for endometrial cancer (EC), and obese patients have a 4.7-fold increased risk compared to the general population to develop the neoplasm. To date, a general pre and postoperative tumor grading agreement from 53 % to 82 % is reported for endometrial analysis, and a consensus on which factors might influence the tumor grading discordance is still absent. Furthermore, although obesity alters the endometrial microenvironment, no studies investigated the role of obesity in the grading agreement of EC patients. This study aims to analyze the role of obesity in the pre and postoperative tumor grading agreement. Materials and methods A retrospective analysis was conducted on EC cancer women subjected to surgical treatment. Upgrading discordance was defined as higher tumor grading on final pathological analysis compared to tumor grading on the preoperative examination. Downgrading discordance was defined as a lower tumor grading at the postoperative surgical specimen analysis compared to the preoperative biopsy. Results Of the 293 selected patients, 245 were included in the analysis. One hundred and forty nine (60.8 %) patients were tumor grade G1, 52 (21.2 %) G2, and 44 (18.0 %) G3. Grading agreement was 83.9 % for G1 patients, 51.9 % for G2 patients, and 83.3 % for G3 patients. The multivariate analysis showed obesity (BMI > 30 kg/m2) as significant factor influencing pre and postoperative grading agreement (p = 0.014, Odds Ratio 2.036, 95 % Confidence Interval 1.141–3.635). Conclusions Our study for the first time showed obesity as the only factor in the multivariate analysis lowering the pre and postoperative tumor grading concordance. Grade 2 tumor was the factor that most frequently disagreed with the final surgical specimen analysis both in the general and in obese patients.

IntroductionThe J-Plasma has recently been introduced into the surgical community with different intrinsic characteristics aimed to further reduce the thermal effect and enhance precision when compared to standard radiofrequency. This study aimed to investigate the role of this new technology in different conditions of gynecological carcinomatosis characterized by the indication for regional peritonectomy and/or ablation, either in laparotomy (LPT) or in laparoscopy (LPS), in the context of a modern personalized approach to the surgical management of gynecological malignancies.Material and MethodsFrom January 2019 to April 2019, 12 patients were selected for this prospective pilot study at the Division of Gynecologic Oncology, Fondazione Policlinico Universitario A. Gemelli IRCCS in Rome. In this single surgeon experience, the inclusion criteria were: histologically proven advanced ovarian/endometrial cancer, primary or interval debulking surgery, and intraoperative indication for regional peritonectomy. Six patients were treated by LPS (Group 1) and 6 by LPT (Group 2).ResultsIn Group 1 the indication for debulking surgery was in 4 cases an interval debulking surgery and 2 advanced endometrial cancer. All patients in Group 2 underwent primary debulking surgery for advanced ovarian cancer. The whole cohort achieved a complete tumor excision after surgery. The median OT and median EBL were 195 min and 100 ml in Group 1, and 420 min and 500 ml in Group 2. The median hospital stay was 4 days in Group 1 and 13 days in Group 2, respectively. No intra and postoperative complications were registered within 60 days after surgery.ConclusionsJ-Plasma allows to approach delicate maneuvers on viscera, mesentery, and blood vessels with a high degree of safety and precision thanks to its limited vertical and lateral thermal spread, favoring the surgeon to push ever higher the cytoreduction/morbidity tradeoff. The use of J-Plasma in cytoreductive surgery could also increase the range of possible minimally invasive procedures, narrowing the technical distance with the open technique and thus contributing to designing a personalized surgical strategy for each patient in different scenarios of peritoneal carcinomatosis.

Borderline ovarian tumor (BOT) accounts for 15–20% of all epithelial ovarian tumors. Concerns have arisen about the clinical and prognostic implications of BOT with exophytic growth patterns. We retrospectively reviewed all cases of BOT patients surgically treated from 2015 to 2020. Patients were divided into an endophytic pattern (with intracystic tumor growth and intact ovarian capsule) and an exophytic pattern (with tumor growth outside the ovarian capsule) group. Among the 254 patients recruited, 229 met the inclusion criteria, and of these, 169 (73.8%) belonged to the endophytic group. The endophytic group showed more commonly an early FIGO stage than the exophytic group (100.0% vs. 66.7%, p < 0.001). Furthermore, tumor cells in peritoneal washing (20.0% vs. 0.6%, p < 0.001), elevated Ca125 levels (51.7% vs. 31.4%, p = 0.003), peritoneal implants (0 vs. 18.3%, p < 0.001), and invasive peritoneal implants (0 vs. 5%, p = 0.003) were more frequently observed in the exophytic group. The survival analysis showed 15 (6.6%) total recurrences, 9 (5.3%) in the endophytic and 6 (10.0%) patients in the exophytic group (p = 0.213). At multivariable analysis, age (p = 0.001), FIGO stage (p = 0.002), fertility-sparing surgery (p = 0.001), invasive implants (p = 0.042), and tumor spillage (p = 0.031) appeared significantly associated with recurrence. Endophytic and exophytic patterns in borderline ovarian tumors show superimposable recurrence rates and disease-free survival.

Introduction: The aim of this study is to analyze the available scientific evidence regarding the quality of life (QoL) and sexual function (SF) in patients affected by cervical cancer (CC) after surgical and adjuvant treatments. Materials and Methods: Preliminary research was conducted via electronic database (MEDLINE, PubMed and Cochrane Library) with the use of a combination of the following keywords: SF, QoL, and CC. The principal findings considered in the present review were the study design, the number of patients included in each study, the information about the malignancy (histology and stage of disease), the questionnaires administered, and the principal findings concerning SF and QoL. Results: All studies were published between 2003–2022. The studies selected consisted of one randomized control study, seven observational studies (three prospective series), and nine case control studies. The scores used were focused on SF, QOL, fatigue, and psychological aspects. All studies reported a decreased SF and QOL. The most developed questionnaires were the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the Female Sexual Function Index (FSFI), the Hospital Anxiety and Depression scale (HADS), and the Female Sexual Distress Scale (FSDS). Discussion: All studies reported a decreased SF and QOL. In addition to the perception of body image, several factors coexist in influencing the outcomes such as the physical, hormonal, psychological. Conclusions: Sexual dysfunction after CC treatment has a multifactorial aetiology which negatively affects the quality of life. For these reasons, it is important to follow and support patients with a multidisciplinary team (doctors, nurses, psychologists, dieticians) before and after therapy. This type of tailored therapeutic approach should become a standard. Women should be informed about possible vaginal changes and menopausal symptoms after surgery and on the positive effects of psychological therapy.

IntroductionOvarian cancer is the third most frequent gynecological cancer. In early stage ovarian cancer (ESOC) comprehensive surgical staging is recommended. Surgical staging is traditionally approached by laparotomy, although minimally invasive surgery can be a valid alternative in selected patients. This study aims to analyze the surgical and oncological outcomes of three different surgical approaches in a large series of patients.MethodsWe retrospectively included all histologically proven ESOC cases treated between January 2014 and December 2017. ESOC was defined as stage IA to IIB according to the 2018 FIGO staging system. Subjects were divided into groups 1, 2, and 3, based on the surgical approach (open abdominal, laparoscopic, or robotic, respectively).ResultsWithin patients enrolled during the study period, 455 met the inclusion criteria. No difference in intraoperative complications was recorded in the three groups (p = 0.709). Conversely, a significant difference occurred in postoperative complications (16.2 vs. 3.8 vs. 11.1%, in groups 1, 2, and 3 respectively, p = 0.004). No difference was found in overall survival (OS) (32 vs. 31 vs. 25 months, p = 0.481) and disease-free survival (DFS) (26 vs. 29 vs. 24 months, p = 0.178) in groups 1, 2, and 3, respectively. At univariate analysis FIGO stage I (p = 0.004) showed a lower recurrence rate compared to FIGO stage II.ConclusionNo significant difference was found in OS and DFS among the three groups (open, laparoscopic, and robotic). The minimally invasive approach showed lower rate of complications than the laparotomic approach.

Background and Objectives: Since the Food and Drug Administration’s (FDA) approval in 2005, the application of robotic surgery (RS) in gynecology has been adopted all over the world. This study aimed to provide an update on RS in benign gynecological pathology by reporting the scientific recommendations and high-value scientific literature available to date. Materials and Methods: A systematic review of the literature was performed. Prospective randomized clinical trials (RCT) and large retrospective trials were included in the present review. Results: Twenty-two studies were considered eligible for the review: eight studies regarding robotic myomectomy, five studies on robotic hysterectomy, five studies about RS in endometriosis treatment, and four studies on robotic pelvic organ prolapse (POP) treatment. Overall, 12 RCT and 10 retrospective studies were included in the analysis. In total 269,728 patients were enrolled, 1721 in the myomectomy group, 265,100 in the hysterectomy group, 1527 in the endometriosis surgical treatment group, and 1380 patients received treatment for POP. Conclusions: Currently, a minimally invasive approach is suggested in benign gynecological pathologies. According to the available evidence, RS has comparable clinical outcomes compared to laparoscopy (LPS). RS allowed a growing number of patients to gain access to MIS and benefit from a minimally invasive treatment, due to a flattened learning curve and enhanced dexterity and visualization.

ObjectivesLaparoscopy is commonly used for endometrial cancer treatment, and sentinel lymph node (SLN) mapping has become the standard procedure for nodal assessment. Despite the standardization of the technique, there is no definitive data regarding its failure rate. The objective of this study is to identify factors associated with unsuccessful SLN mapping in endometrial cancer patients undergoing laparoscopic SLN mapping after intracervical indocyanine green (ICG) injection.MethodsWe retrospectively evaluated a consecutive series of endometrial cancer patients who underwent laparoscopic SLN mapping with intracervical ICG injection, in four oncological referral centers from January 2016 to July 2019. Inclusion criteria were biopsy-proven endometrial cancer, total laparoscopic approach, and intracervical ICG injection. Exclusion criteria were evidence of lymph node involvement or extrauterine disease at pre-operative imaging, synchronous invasive cancer, the use of tracers different from ICG, and the use of neoadjuvant treatment. Bilateral and failed bilateral SLN mapping groups were compared for clinical and pathological features. In patients with an unsuccessful procedure, side-specific lymphadenectomy was performed. Logistic regression was used to identify predictors of failure.ResultsA total of 376 patients were included in the study. The overall bilateral and unilateral SLN detection rates were 96.3%, 76.3%, and 20.0% respectively. The failed bilateral mapping detection rate was 23.7%. The median number of sentinel nodes removed was 2.2 (range, 0–5). After multivariate analysis, lymph vascular space involvement [OR 2.4 (1.04–1.12), P=0.003], non-endometrioid histology [OR 3.0 (1.43–6.29), P=0.004], and intraoperative finding of enlarged lymph node [OR 2.3 (1.01–5.31), P=0.045] were identified as independent predictors of failure of SLN mapping.ConclusionLymph vascular space involvement, non-endometrioid histology, and intra-operative finding of enlarged lymph nodes were identified as independent risk factors for unsuccessful mapping in patients undergoing laparoscopic SLN mapping.

Objective This review aims to analyze the pathological aspects, diagnosis and treatment of rare mesenchymal uterine tumors. Methods On August 2019, a systematic review of the literature was done on Pubmed, MEDLINE, Scopus, and Google Scholar search engines. The systematic review was carried out in agreement with the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes statement (PRISMA). The following words and key phrases have been searched: "endometrial stromal sarcoma", "low-grade endometrial stromal sarcoma", "high-grade endometrial stromal sarcoma", "uterine sarcoma", "mesenchymal uterine tumors" and "uterine stromal sarcoma". Across these platforms and research studies, five main aspects were analyzed: the biological characteristics of the neoplasms, the number of cases, the different therapeutic approaches used, the follow-up and the oncological outcomes. Results Of the 94 studies initially identified, 55 were chosen selecting articles focusing on endometrial stromal sarcoma. Of these fifty-five studies, 46 were retrospective in design, 7 were reviews and 2 randomized phases III trials. Conclusion Endometrial stromal sarcomas are rare mesenchymal uterine neoplasms and surgery represents the standard treatment. For uterus-limited disease, the remove en bloc with an intact resection of the tumor (without the use of morcellation) is strongly recommended. For advanced-stage disease, the standard surgical treatment is adequate cytoreduction with metastatectomy. Pelvic and para-aortic lymphadenectomy is not recommended in patients with Low-grade Endometrial Stromal Sarcoma (ESS), while is not clear whether cytoreduction of advanced tumors improves patient survival in High-grade ESS. Administration of adjuvant radiotherapy or chemotherapy is not routinely used and its role is still debated.

Nowadays, no standard approaches for follow up in ovarian cancer (OC) patients exist. While the role of ultrasound (US) is well defined in primary diagnosis of OC, it is still controversial during follow-up of surgically treated OC. The aim of this narrative review is to evaluate the role described in literature of US imaging in the early detection of OC recurrences. A review of the English literature present in PubMed and SCOPUS of the past 30 years regarding the use of US in recurrent ovarian cancer (ROC) has been performed. The following keywords were searched: "ultrasound and recurrent ovarian cancer" and "intraoperative ultrasound and recurrent ovarian cancer". A total of 15 articles were selected. US was mainly adopted in the detection of recurrent pelvic disease after debulking surgery, after fertility sparing surgery (FSS) and as an intraoperative tool for localization of OC recurrences. If introduced as a standard follow-up procedure, US may have a central role in the early detection of pelvic OC recurrence, in ovarian localization of relapses of borderline ovarian tumor (BOT) and early stages disease treated with FSS; it may also play an important role in the intraoperative localization of previously suspected secondary lesions.

Nowadays, the best treatment option for ovarian cancer recurrence is often subjective, can vary in the different centers and depend on personal experience. Arbeitsgemeinschaft Gynaekologische Onkologie (AGO)-DESKTOP studies have identified a population of patients who could benefit from secondary surgery. The results of the Gynecologic Oncology Group (GOG)-0213 study were recently published, which showed no advantage in terms of overall survival (OS) in patients with platinum-sensitive recurrent epithelial ovarian undergoing secondary cytoreductive surgery (SCS) compared to chemotherapy alone. Aim of this narrative review is to summarize the best aspects that can make ovarian cancer recurrence patients suitable for SCS. A narrative review analyzing all the literature of the past 30 years has been performed. PubMed, Scopus, Web of Science and Ovid MEDLINE were used for research. All non-English-language articles have been excluded. The following keywords were searched: 'recurrent ovarian cancer', 'secondary surgery', 'secondary cytoreductive surgery', 'platinum-sensitive ovarian cancer', 'platinum-resistant ovarian cancer'. We divided eligible patients for secondary cytoreduction in relation to the following factors: platinum-sensitivity, AGO-score or Tian model, unresectable lesions, surgical generic contraindication, woman's personal choice. The selection of truly suitable patients for surgery seems an essential requirement for the patient's best therapeutic choice. In case of absent post-surgical residual tumor, good performance status, single recurrence, and platinum-sensitive ovarian recurrence, surgery could be performed.

Since the first robotic single-site hysterectomy was performed, the research focused on the use of robotic single-site surgery (RSSS) for all gynecological conditions. This review aims to examine the studies available in the literature on RSSS in gynecology both for benign and malignant indications. The systematic review was carried out in agreement with the preferred reporting items for systematic reviews and meta-analyses statement (PRISMA). All the articles were grouped into three sets based on the surgical indication (Group 1, 2, and 3 for benign, malignant, and mixed diseases, respectively). Two hundred and fifty total studies were analyzed, and 27 articles were included in the review. A total of 1065 patients were included in the analysis. Of these, 605 patients were included in group 1, 260 in group 2, and 200 in group 3. Ten (1.7%) patients with benign pathology, 16 (6.2%) patients with malignant disease, and 5 (2.5%) patients with both diseases developed major complications. Two (0.3%) patients in group 1, 3 (1.2%) patients in group 2 and 5 (2.5%) in group 3 were converted to a different type of surgery. No significant differences were found between groups for BMI (p = 0.235), operative time (p = 0.723), estimated blood loss (EBL) (p = 0.342), and hospital stay (p = 0.146). The complications and conversions incidence through pooled analysis showed a higher general conversion rate (p = 0.012) in group 3 (3.0%) and higher complications rate (p = 0.001) in group 2 (5.3%) compared to the other groups. RSSS seems to be a feasible and safe procedure for all gynecological surgical procedures. A long-term analysis would be necessary before considering the RSSS oncologically safe for patients with malignant disease.

Study Objective: The effect of the different types of vaginal cuff closures on posthysterectomy sexual function has not been investigated in depth. We evaluated if there is a difference between transvaginal versus a laparoscopic closure after total laparoscopic hysterectomy (TLH) on female sexual function, using a validated questionnaire. Design: Secondary analysis of a prospective randomized controlled trial. Setting: Three academic research centers. Patients: Women consenting to telephone interviews on their sexual life before and after undergoing TLH were included. Interventions: Patients were randomly assigned to a laparoscopic or transvaginal approach for vaginal cuff closure at the end of TLH for benign indications. Measurements and Main Results: A validated questionnaire (the Female Sexual Function Index [FSFI]) was used to explore sexuality before and after the operation. Of the 1408 patients enrolled in the primary study, 400 patients were asked to complete the questionnaire. Of them, 182 (41.4%) were eligible and accepted enrollment in the present analysis. No difference was found in terms of pre- and postoperative FSFI scores between groups. Patients with a low preoperative FSFI score (

ObjectiveSentinel lymph node (SLN) mapping represents the standard approach in uterine confined endometrial cancer patients. The aim of this study was to evaluate the anatomical distribution of SLNs and the most frequent locations of nodal metastasis.MethodsThis was an observational retrospective multicenter study involving eight high volume gynecologic cancer centers in Italy. We reviewed 1576 patients with a histologically confirmed diagnosis of endometrial cancer from September 2015 to June 2020. All patients underwent total hysterectomy with salpingo-ophorectomy and SLN mapping.ResultsA total of 3105 SLNs were mapped and removed, 2809 (90.5%) of these were bilateral and 296 (9.5%) unilateral. The overall detection rate was 93.4% (77.9% bilateral and 15.5% unilateral). The majority of SLNs (80%) and positive SLNs (77.8%) were found at the external iliac and obturator level in both endometrioid and non-endometrioid endometrial cancer. Negative SLNs were more frequent in patients with endometrioid compared with non-endometrioid cancer (91.9% vs 86.1%, pConclusionThe most frequent sites of SLNs and metastases were located in the pelvic area below the iliac vessel bifurcation. Our findings showed that older age, a higher body mass index, and non-endometrioid histology had a negative impact on mapping.

Dissolution Dynamic Nuclear Polarization (dDNP) was invented almost twenty years ago. Ever since, hardware advancement has observed 2 trends: the quest for DNP at higher field and, more recently, the development of cryogen free polarizers. Despite the DNP community is slowly migrating towards “dry” systems, many “wet” polarizers are still in use. Traditional DNP polarizers can use up to 100 L of liquid helium per week, but are less sensitive to air contamination and have higher cooling power. These two characteristics make them very versatile when it comes to new methods development.In this study we retrofitted a 5 T/1.15 K “wet” DNP polarizer with the aim of improving cryogenic and DNP performance. We designed, built, and tested a new DNP insert that is compatible with the fluid path (FP) technology and a LOgitudinal Detected Electron Spin Resonance (LOD-ESR) probe to investigate radical properties at real DNP conditions. The new hardware increased the maximum achievable polarization and the polarization rate constant of a [1-13C]pyruvic acid-trityl sample by a factor 1.5. Moreover, the increased liquid He holding time together with the possibility to constantly keep the sample space at low pressure upon sample loading and dissolution allowed us to save about 20 L of liquid He per week.

Aortic lymph node metastases are a relative common finding in locally advanced cervical cancer. Minimally invasive surgery is the preferred approach to perform para-aortic lymph nodal staging to reduce complications, hospital stay, and the time to primary treatment. This meta-analysis (CRD42022335095) aimed to compare the surgical outcomes of the two most advanced approaches for the aortic staging procedure: conventional laparoscopy (CL) versus robotic-assisted laparoscopy (RAL). The meta-analysis was conducted according to the PRISMA guideline. The search string included the following keywords: “Laparoscopy” (MeSH Unique ID: D010535), “Robotic Surgical Procedures” (MeSH Unique ID: D065287), “Lymph Node Excision” (MeSH Unique ID: D008197) and “Aorta” (MeSH Unique ID: D001011), and “Uterine Cervical Neoplasms” (MeSH Unique ID: D002583). A total of 1324 patients were included in the analysis. Overall, 1200 patients were included in the CL group and 124 patients in the RAL group. Estimated blood loss was significantly higher in CL compared with RAL (p = 0.02), whereas hospital stay was longer in RAL compared with CL (p = 0.02). We did not find significant difference for all the other parameters, including operative time, intra- and postoperative complication rate, and number of lymph nodes excised. Based on our data analysis, both CL and RAL are valid options for para-aortic staging lymphadenectomy in locally advanced cervical cancer.

Conflicting data exists on the impact of Body Mass Index (BMI) on sentinel lymph-node (SLN) detection. The primary study endpoint was to investigate the impact of obesity on overall detection rate, bilateral mapping, and mapping failure rate of SLN. In addition, we evaluated possible differences in terms of surgical management and "empty-packet dissection" rate among obese and non-obese patients.Multicenter, propensity-matched, retrospective study. Patients with apparent early-stage endometrial cancer were included. Study population was divided into women with BMI/≥ 30 (Group-1 and Group-2). To lower the selection bias, a propensity-matched analysis was performed. Matching was based on histotype (endometrioid vs non-endometrioid), age (/≥65 years old), and presence of lymph-vascular space invasion.Eight-hundred forty-four women were enrolled. After a 1:1 propensity-matched analysis, 764 patients were identified (Group-1 n = 382, Group-2 n = 382). A 1.156-fold increase in the risk of mapping failure for every 5 units of BMI increase was found (OR 1.156, 95% CI 1.033-1.294, p = 0.012), with a consequently decrease in bilateral mapping and overall detection rate (respectively OR 0.865, 95% CI 0.773-0.968, p = 0.012 and OR 0.785, 95% CI 0.670-0.920, p = 0.003). Obese patients were surgically under-staged in 9.4% of cases and showed an 8.2% of empty packet dissection (surgical under-staging: 5.0% vs 9.4%, p = 0.017; empty-packet dissection: 3.9% vs 8.2%, p = 0.022).BMI was confirmed as a statistically relevant predictor of mapping failure and decreased overall detection rate. In addition, obese women had a significantly higher odds of empty packet dissection.

Background: Sentinel lymph node (SLN) biopsy is considered the standard of care in early-stage endometrial cancer (EC). For SLN failure, a side-specific lymphadenectomy is recommended. Nevertheless, most hemipelvises show no nodal involvement. The authors previously published a predictive score of lymphovascular involvement in EC. In case of a negative score (value 3–4), the risk of nodal metastases was extremely low. This multicenter study aimed to analyze a predictive score of nodal involvement in EC patients. Methods: The study enrolled patients with EC who had received comprehensive surgical staging with nodal assessment. A preoperative predictive score of nodal involvement was calculated for all the patients before surgery. The score included myometrial infiltration, tumor grading (G), tumor diameter, and Ca125 assessment. The STARD (standards for Reporting Diagnostic accuracy studies) guidelines were followed for score accuracy. Results: The study analyzed 1038 patients and detected 155 (14.9%) nodal metastases. The score was negative (3 or 4) for 475 patients and positive (5–7) for 563 of these patients. The score had a sensitivity of 83.2%, a specificity of 50.8%, a negative predictive value of 94.5%, and a diagnostic value of 55.7%. The area under the curve was 0.75. The logistic regression showed a significant correlation between a negative score and absence of nodal metastasis (odds ration [OR], 5.133, 95% confidence interval [CI], 3.30–7.98; p < 0.001). Conclusion: The proposed predictive score is a useful test to identify patients at low risk of nodal involvement. In case of SLN failure, the application of the current score in the SLN algorithm could allow avoidance of unnecessary lymphadenectomies.

Introduction/Background* Ovarian cancer is the third most frequent gynecological cancer. In early stage ovarian cancer (ESOC) comprehensive surgical staging is recommended. Surgical staging is traditionally approached by laparotomy, although minimally invasive surgery can be a valid alternative in selected patients. This study aims to analyze the surgical and oncological outcomes of these three different approaches in a large series of patients. Methodology We retrospectively included all histologically proven ESOC cases treated between January 2014 and December 2017. ESOC was defined as stage IA to IIB according to the 2018 FIGO staging system. Subjects were divided into groups 1, 2, and 3, based on the surgical approach (open abdominal, laparoscopic, or robotic, respectively). Result(s)* Within patients enrolled during the study period, 455 met the inclusion criteria. No difference in intraoperative complications was recorded in the three groups (p=0.709). Conversely, a significant difference occurred in postoperative complications (16.2% vs. 3.8% vs. 11.1%, in groups 1, 2, and 3 respectively, p=0.004). No difference was found in overall survival (OS) (32 vs. 31 vs. 25 months, p=0.481) and disease-free survival (DFS) (26 vs. 29 vs. 24 months, p=0.178) in groups 1, 2, and 3, respectively. At univariate analysis FIGO stage I (p=0.004) showed a lower recurrence rate compared to FIGO stage II. Conclusion* No significant difference was found in OS and DFS among the three groups (open, laparoscopic, and robotic). The minimally invasive approach showed lower rate of complications than the laparotomic one, thus it should be preferred in selected patients.

Introduction/Background* Obese patients pose both surgical and anesthetic challenges, as their comorbidities contribute to adverse outcomes. In this setting, minimally invasive approach and the introduction of the Sentinel Lymph-Node (SLN) algorithm in endometrial cancer (EC) treatment acquire a particular relevance, allowing to reduce both operative times and surgical difficulties. However, conflicting data exists on the impact of Body Mass Index (BMI) on SLN detection. The primary study endpoint was to investigate the impact of obesity on overall detection rate, bilateral mapping, and mapping failure rate. In addition, we evaluated possible differences in terms of surgical management and ‘empty packet dissection’ rate among the two study groups. Methodology Multicenter, propensity-matched, retrospective study. Data of patients with apparently early-stage EC were retrospectively retrieved. Study population was divided into women with BMI Result(s)* Eight-hundred forty-four women were enrolled in the study. After a 1:1 propensity matched analysis, a total of 764 patients were identified (Group-1 n=382, Group-2 n=382). A 1.156-fold increase in the risk of mapping failure for every 5 units of increase in BMI (OR 1.156, 95% CI 1.033-1.294, p=0.012) was found, with a consequently decrease in bilateral mapping and overall detection rate (respectively OR 0.865, 95% CI 0.773-0.968, p=0.012 and OR 0.785, 95% CI 0.670-0.920, p=0.003) (figure 1). Furthermore, in the group of obese patients, in 25 cases (7.4%) the SLN dissection did not lead to the identification of lymph-node tissue at final histopathological examination (’empty packet dissection’) (Group1 vs Group 2: 3.9% vs 7.4%, p=0.046) (table 1). Conclusion* Controlling for the variables that have been proved to negatively influence the SLN detection rate, BMI was confirmed as a statistically relevant predictor of mapping failure. In addition, obese women had a significantly higher odds of empty packet dissection, which could lead to an un-intended surgical understaging.
