Endometrioid ovarian carcinoma landscape: pathological and molecular characterization.

Endometrioid ovarian cancers (EOvC) are usually managed as serous tumors. In this study, we conducted a comprehensive molecular investigation to uncover the distinct biological characteristics of EOvC. This retrospective multicenter study involved patients from three European centers. We collected clinical data and formalin-fixed paraffin-embedded (FFPE) samples for analysis at the DNA level using panel-based next-generation sequencing and array-comparative genomic hybridization. Additionally, we examined mRNA expression using NanoString nCounter® and protein expression through tissue microarray. We compared EOvC with other ovarian subtypes and uterine endometrioid tumors. Furthermore, we assessed the impact of molecular alterations on patient outcomes, including progression-free survival (PFS) and overall survival (OS). Preliminary analysis of clinical data from 668 patients, including 86 (12.9%) EOvC, revealed more favorable prognosis for EOvC compared with serous ovarian carcinoma (5-year OS of 60% versus 45%; P = 0.001) driven by diagnosis at an earlier stage. Immunohistochemistry and copy number alteration (CNA) profiles of 43 cases with clinical data and FFPE samples available indicated that EOvC protein expression and CNA profiles were more similar to endometrioid endometrial tumors than to serous ovarian carcinomas. EOvC exhibited specific alterations, such as lower rates of PTEN loss, mutations in DNA repair genes, and P53 abnormalities. Survival analysis showed that patients with tumors harboring loss of PTEN expression had worse outcomes (median PFS 19.6 months vs. not reached; P = 0.034). Gene expression profile analysis confirmed that EOvC differed from serous tumors. However, comparison to other rare subtypes of ovarian cancer suggested that the EOvC transcriptomic profile was close to that of ovarian clear cell carcinoma. Downregulation of genes involved in the PI3K pathway and DNA methylation was observed in EOvC. In conclusion, EOvC represents a distinct biological entity and should be regarded as such in the development of specific clinical approaches.

Challenges in the diagnosis and management of Robert's uterus: Systematic review and case presentation.

Robert's uterus is a rare Müllerian duct anomaly (MDA) characterized by complete asymmetric septum dividing uterine cavity into two non-communicating parts. This study offers insights into diagnosing and management of this condition in a young patient, and a systematic literature review. The review included 19 studies from 2013 to 2023. 11.4% of women reported a history of miscarriage and 5.7% primary infertility. Dysmenorrhea was the most frequent symptom (54.3%), and 14.3% of patients had a coexisting endometriosis. The surgical interventions most commonly combine laparoscopic and hysteroscopic techniques. Robert's uterus requires heightened clinical awareness for early diagnosis, particularly in young women.

Is minimally invasive surgical approach a reasonable option in apparent early stage epithelial ovarian cancer restaging? Results from a multicentric retrospective study.

INTRODUCTION: To perform surgical staging of early stage ovarian cancer (EOC), conventional laparoscopy (LS) and robot-assisted laparoscopy (RLS) appear to be reliable procedures compared to open surgery. But oncologicals results with long-term follow up are limited in the literature. The objective of this study is to evaluate the surgical and long-term survival for patients managed by minimally invasive surgery (MIS). MATERIALS AND METHODS: We conducted a multicentric retrospective study in 6 institutions. All patients referred for epithelial EOC (apparent stage I-IIa) managed with LS and RLS were involved. RESULTS: From December 2008 to December 2017, 140 patients were included (109 in LS group and 31 in RLS group). A total of 27 (19.2 %) patients were upstaged to an advanced ovarian cancer (FIGO stage > IIA), and 73 % of patients received chemotherapy. Mean operative time was 265,8 ± 88,4 min and significantly longer in RLS group (LS = 254,5 ± 86,8; RLS = 305,6 ± 85,5; p = 0,008). Rate of severe post-operative complications (grade 3) was 5,7 %. Thirteen conversion to laparotomy occurred, including one per-operative hemorrhaege. After a mean follow-up of 60,7 months, 29 (20.7 %) patients recurred, with a time to recurrence was >24 months in 51,7 % of cases. Overall survival (OS) was 88.6 % and disease-free survival (DFS) was 79.3 %. Oncologic outcomes were similar between LS and RLS group (OS: p = 0,504 and DFS: p = 0,213). CONCLUSION: Surgical staging of EOC by LS or RLS approach has long-term equivalent surgical and oncological approach. These results seem to be equivalent to open surgery according to literature review.

Rate of Vaginal Cuff Dehiscence When Using Vicryl (Poliglactyn 910) Compared to PDS (Polydioxanone) for Vaginal Cuff Closure in Laparoscopic Hysterectomy.

Objective: To compare the vaginal cuff dehiscence (VCD) rates using Vicryl (Poliglactyn 910) and Polydioxanone (PDS) in patients who underwent laparoscopic hysterectomy. Materials and methods: A retrospective, monocentric study was conducted, including all patients undergoing laparoscopic hysterectomy at the Department of Obstetrics and Gynaecology, Azienda di Rilievo Nazionale e di Alta Specializzazione (ARNAS) Garibaldi Nesima, Catania, between January 2014 and December 2021. Patients underwent hysterectomy for benign gynecologic pathologies (endometriosis, leiomyomas, or benign pelvic pathologies) or malignant gynecologic pathologies (endometrium cancer, complex endometrial hyperplasia, ovarian cancer, cervix cancer, or uterine carcinosarcoma). The Z-score calculation was performed to find eventual statistically significant differences between the two populations regarding VCD rates. Results: Laparoscopic vaginal cuff closure was performed, with Vicryl sutures in 202 patients and PDS sutures in 184 women. Demographic and baseline characteristics were not significantly different in the two groups. VCD occurred in three patients in the Vicryl group and did not occur in the PDS group. The three cases of VCD were precipitated by intercourses that occurred within 90 days of surgery. However, there was not a significant statistical difference between the two groups regarding VCD (p = 0.09). Conclusions: Vicryl and PDS sutures seem to be similar for vaginal cuff closure in laparoscopic hysterectomy. The VCD rate was low, and the observed differences between the Vicryl and PDS groups did not reach statistical significance. Further research through prospective studies is essential.

Meningioma in the third trimester of pregnancy: A case report.

Meningiomas are rare benign tumors during pregnancy. They can put both the mother and the fetus at risk because rapid changes in size may occur. The study reports a case of olfactory groove meningioma in a 34-year-old pregnant woman with visual impairment, anosmia, and dysgeusia that increased in severity during the 29th week of gestation. Magnetic resonance imaging showed an olfactory groove meningioma. The patient underwent a preterm cesarean section to avoid the worsening of the clinical condition due to intracranial compression phenomena. A computed tomography scan of the brain supported the diagnosis. The surgical intervention occurred on the third day after delivery. The clinical course was uneventful and the chiasmal syndrome improved in the following 2 months. Meningiomas in pregnancy may present unique challenges and have a wide array of clinical presentations. Management of maternal meningiomas can be complex and requires a multidisciplinary approach. The treatment decision largely depends on the size and location of the tumor, the presence of symptoms, gestational age, and fetal well-being. Further research is needed to enhance the understanding of the underlying mechanisms and improve management approaches for this rare condition.

Hysteroscopic Findings and Operative Treatment: All at Once?

Hysteroscopy is considered not only a diagnostic instrument but also a therapeutic tool for many uterine pathologies. In the early 1990s, advances in technology and techniques made hysteroscopy less painful and invasive, allowing to increase in the number of gynecological procedures performed in an ambulatory setting without significant patient discomfort and with potentially significant cost savings. This is the so-called "office hysteroscopy" or "see-and-treat hysteroscopy", whose spread has permitted the decrease of the number of procedures performed in the operating room with the benefit of obviating the need for anesthesia and dilatation of the cervical canal.

Anti-Mullerian Hormone (AMH) and adenomyosis: Mini-review of literature of the last 5 years.

Introduction: Adenomyosis is a form of endometriosis characterized by the presence of endometrial tissue in the myometrium. The correlation between anti-Mullerian hormone (AMH) expression and adenomyosis is unclear. Few studies investigated this possible correlation with promising results. The aim of this mini-review is to illustrate the potential prognostic and therapeutic role of AMH in adenomyosis. Materials and methods: A study protocol was completed conforming to the Preferred Reporting Items for Reviews and Meta-Analyses (PRISMA) guidelines for systematic reviews. We performed an electronic databases search from each database's inception from August 2017 to August 2022 for full-text articles and published abstracts. For database searches, the following main keywords were the following text words: "adenomyosis" or "uterine endometriosis" [Mesh] AND "AMH" or "anti-mullerian hormone". Results: From the literature search, 8 abstracts of studies were retrieved and independently screened for inclusion by three authors. It was found that the most common therapeutic strategies (such as adenomyomectomy and high-intensity focused ultrasound (HIFU) do not alter AMH levels. Moreover, a higher expression of the AMH receptor II was observed in adenomyotic tissue, hence a possible therapeutic use of AMH was hypothesized. Conclusion: The available evidence shows an unclear relationship between adenomyosis and AMH. Probably, women with adenomyosis have lower levels of AMH and the surgical treatment (adenomyomectomy, HIFU) does not alter this characteristic, therefore in all of them, ovarian function is not influenced.

Isolated Tubal Torsion in a Term Pregnancy: Case Report and Systematic Review of Literature of the Last 10 Years.

Objective: Isolated torsion of a fallopian tube is a rare event and it is extremely difficult to be diagnosed in pregnancy. The aim of this study is to present a clinical case report that occurred in our department and to summarize the latest evidence about tubal torsion in pregnancy. Methods: We reported data, ultrasonographic features and an intra-operative image of a case report of tubal torsion in a term pregnancy. Then a review of the literature was performed following the PRISMA statement: we searched all the articles related to tubal torsion in pregnancy in the last 10 years from the international electronic bibliographic database PUBMED. We collected data regarding population characteristics, clinical features, treatment, and feto-maternal outcomes. Results: According to our search strategy, 10 articles were included. The main clinical symptoms were abdominal pelvic pain (100%), nausea, and vomiting (30%). The mean gestational age at the diagnosis was 36 weeks after the last menstrual period in 50% of cases. Ultrasound images showed a cystic lesion in the adnexal area in 70% of cases. In most of the cases, a cesarean section with a contextual salpingectomy was performed. No cases of maternal and fetal death were respectively reported. Conclusion: Isolated torsion of the fallopian tube is a rare obstetric condition but it should be considered in case of acute lower abdominal pain presentation during pregnancy. Depending on gestational age, surgical treatment as soon as possible could prevent a salpingectomy.

Feasibility and surgical outcomes of conventional and robot-assisted laparoscopy for early-stage ovarian cancer: a retrospective, multicenter analysis.

PURPOSE: We aimed to investigate the safety, adequacy and oncological outcomes of laparoscopic surgery (LS) and robot-assisted laparoscopic (RALS) approach for the treatment of early-stage ovarian cancer. METHODS: We performed a multicentric, retrospective cohort study, enrolling patients affected by early-stage ovarian cancer who underwent laparoscopic management for early-stage ovarian cancer between 2006 and 2014. Surgical, pathologic and oncologic outcome data were analyzed to compare LS and RALS performances for early-stage ovarian cancer management. RESULTS: 39 patients underwent laparoscopic staging for presumed stage I ovarian cancer: 23 underwent LS and 16 underwent RALS. The mean operative time was 281 ± 81 min (LS 288 ± 88 min; RALS 270 ± 72 min; p = 0.49). No conversion to laparotomy occurred, and one patient had intraoperative hemorrhage requiring blood transfusion. Four patients (10.2 %) experienced postoperative complications of grade 3 according to the Clavien-Dindo classification. The median hospital stay was 3 days (1-15); the differences were not statistically significant between two groups [LS = 4 (1-15); RALS = 3 (1-7); p = 0.43]. During a mean follow-up period of 19.4 months, tumor recurrence occurred in 3 patients: 2 (8.7 %) in the LS group and 1 (6.25 %) in the RALS group. Overall survival and disease-free survival for the entire cohort were 97.4 and 92.3 %, respectively. CONCLUSIONS: LS and RALS seem to be adequate and feasible for the treatment of early-stage ovarian cancer in terms of the surgical outcomes and oncological safety. Furthermore, in our experience, perioperative outcomes are comparable between LS and RALS making them an acceptable approach in selected patients.

Comparison of single-port laparoscopy and conventional laparoscopy for extraperitoneal para-aortic lymphadenectomy.

BACKGROUND: Extraperitoneal para-aortic lymphadenectomy (PAL) is used to treat gynecological cancers. This laparoscopic approach was first described using a multiport technique, and more recently, a single-port technique was developed. Our aim was to experimentally compare both approaches-conventional laparoscopy (CL) and single-port laparoscopy (SPL)-via the extraperitoneal laparoscopic approach. METHODS: From November 2006 to July 2012, extraperitoneal PAL was performed by CL or SPL using the GelPOINT device (Applied Medical). The surgical outcomes of the 2 groups were statistically analyzed. RESULTS: The study involved 69 patients; 36 underwent PAL with CL, and 33 patients underwent PAL with SPL. The mean operative times were 211.2 (range, 132-390) min and 159.6 (range, 120-255) min for the CL and SPL groups, respectively. The mean blood loss was not significantly different between the CL (52.5 mL; range, 0-100 mL) and SPL (40.5 mL; range, 0-100 mL, p = 0.62) groups. The average lymph node count was lower in the CL group (11.1; range, 4-29) compared to the SPL group (15; range, 3-19) (p = 0.03). However, this difference was not confirmed in the multivariate analysis (p = 0.16). The mean hospital stay was lower for the SPL group (2.2 days; range, 1-8 days) than the CL group (3.1 days; range, 1-5 days). In this case, the significant difference found in the univariate analysis (p = 0.02) was confirmed by the multivariate analysis (p = 0.0003). There were no conversions to open technique and no major complications. CONCLUSIONS: The SPL method appears to be a feasible approach, with surgical outcomes that are not statistically different from the CL method. The cosmetic aspect, the role of SPL in decreasing postoperative pain, and its impact on hospital stay must be confirmed prospectively in larger series.

Robotically assisted laparoscopy for paraaortic lymphadenectomy: technical description and results of an initial experience.

OBJECTIVE: The objective of this study is to demonstrate the feasibility of robotically assisted laparoscopy paraaortic lymphadenectomy (PAL), isolated or combined with another procedure using different surgical approaches. METHODS: From February 2007 to December 2010, 53 patients underwent paraaortic lymphadenectomy up to the left renal vein. We used three different approaches with three different positions for the robot in relation to the surgical procedure (isolated transperitoneal PAL, isolated extraperitoneal PAL, or transperitoneal PAL combined with another procedure). Thirty-nine patients underwent isolated lomboaortic lymphadenectomy and 14 a combined procedure. Information concerning installation time, operative time, peri- and postoperative complications, blood loss, lymph node count, and conversion rate was recorded. RESULTS: For the whole population, mean installation time was 33 ± 18 min, mean operative time was 197 ± 81 min, and mean hospital stay was 3.9 ± 2.8 days. We observed 15.1% lymph node involvement at definitive pathology. Between isolated trans- and extraperitoneal PAL, only body mass index (BMI, 27.4 versus 22 kg/m(2)) was significantly different. No difference was observed concerning mean number of lymph nodes or hospital stay. We observed statistical difference between combined and isolated PAL concerning mean operative time (256 versus 160 min), mean number of lymph nodes (7.8 versus 14.6), and hospital stay (5.9 versus 2.9 days). CONCLUSIONS: Although laparoscopic robotic-assisted PAL is a safe and feasible procedure, lymph node staging seems to be better if the procedure is isolated. In case of combined procedures, the surgical approach should be modified regarding patient BMI and the associated procedure, to increase lymph node count.

Laparoscopic extraperitoneal aortic dissection: does single-port surgery offer the same possibilities as conventional laparoscopy?

BACKGROUND: This study aimed to demonstrate the feasibility of single-port surgery (SPS) for laparoscopic extraperitoneal aortic dissection. METHODS: From December 2010 to April 2011, all patients referred for aortic lymph node staging underwent a laparoscopic extraperitoneal approach with a single-port device. The extraperitoneal approach was performed using only one 3-4 cm incision on the left side. Gelpoint from Applied Medical (Rancho Santa Margarita, CA, USA), a 10-mm 0° laparoscope, and 5-mm standard instruments were used. RESULTS: The study enrolled 13 patients. Aortic dissection was complete for 11 patients and incomplete for 2 patients. The mean lymph node count was 16 (range, 7-40). The mean blood loss was 40.7 ml (range, 0-100 ml), and no transfusion was necessary. The mean hospital stay was 1.7 days (range, 1-4 days) for this series. CONCLUSION: The study results demonstrate the feasibility of single-port-access laparoscopy for extraperitoneal aortic lymphadenectomy. The lymph node count was similar to that described in the published experience of conventional laparoscopic extraperitoneal dissection. This preliminary report shows that SPS is usable for extraperitoneal aortic dissection and that it is possible to perform this procedure using only one skin incision compared with the three or four incisions required for conventional laparoscopy.
