Pancreatic neuroendocrine tumor progression and resistance to everolimus: the crucial role of NF-kB and STAT3 interplay

PURPOSE

The finding of mTOR overactivation in patients affected by pancreatic neuroendocrine tumors (Pa-NETs) led to their treatment with the mTOR inhibitor everolimus. Unfortunately, the efficacy of everolimus is restricted by the occurrence of resistance. The mechanisms leading to Pa-NETs' progression and resistance are not well understood. Notably, chronic inflammation is implicated in NET development. NF-kB is involved in inflammation and drug resistance mechanisms through the activation of several mediators, including STAT3. In this respect, NF-κB and STAT3 interaction is implicated in the crosstalk between inflammatory and tumor cells.

METHODS

We investigated the expression of NF-kB in different Pa-NETs by RT-qPCR and immunohistochemistry. Then, we studied the role of NF-κB and STAT3 interplay in QGP-1 cells. Subsequently, we assessed the impact of NF-κB and STAT3 inhibitors in QGP-1 cell proliferation and spheroids growth. Finally, we evaluated the implication of the NF-kB pathway in everolimus-resistant Pa-NET cells.

RESULTS

We found that the increased NF-kB expression correlates  with a higher grade in Pa-NETs. The activation of the STAT3 pathway induced by TNFα is mediated by NF-kB p65. NF-kB p65 and STAT3 inhibitors decrease QGP-1 viability, spheroids growth, and Pa-NETs cell proliferation. These effects are maintained in everolimus-resistant QGP-1R cells. Interestingly, we found that NF-kB, STAT3, IL-8, and SOCS3 are overexpressed in QGP-1R compared to QGP-1.

CONCLUSION

Since the NF-kB pathway is implicated in Pa-NETs' progression and resistance to everolimus, these data could explain the potential use of NF-kB as a novel therapeutic target in Pa-NET patients.

Effect of maternal age and BMI on induction of labor using oral misoprostol in late-term pregnancies: a retrospective cross-sectional study

OBJECTIVES

To evaluate the effect of maternal age and body mass index (BMI) on oral misoprostol induction of labor for late-term pregnancies.

DESIGN

Retrospective cross-sectional study (ClinicalTrial iD: NCT06184139), including only late-term pregnancies in healthy nulliparous women and single cephalic fetus with normal birthweight. Specify the type of study (randomized, prospective cohort, case-control, other) and include the number of study subjects (cases/controls), treatment type and duration, sampling procedures if applicable.

PARTICIPANTS/MATERIALS, SETTING, METHODS

One-hundred-and-four pregnant women underwent induction of labor with oral misoprostol for late-term pregnancy on the 290th day of gestation. Study population was divided in two groups based on age (<35 and ≥35 years) and obesity (BMI <30 and ≥30). Statistical analysis was performed using SPSS V.21.0 (IBM Corporation, Armonk, NY). The inclusion of 51 women from each of the two arms achieved 80% power with an alpha error of 0.05. Continuous variables were expressed as the mean and standard deviation (SD). Categorical variables are expressed as frequencies and percentages. Results No statistically significant differences were recorded between younger and older women. Obese women reported a longer time between the last dose of misoprostol and cervical dilation of 6 cm (p=0.01), a longer time between the last dose of misoprostol and delivery (p=0.04), and a higher rate of grade II vaginal lacerations (p=0.02). Limitations While this study contributes novel insights into cervical ripening and labor induction using oral misoprostol for late-term pregnancies, its scope is limited by the retrospective study design, inherently carrying biases compared to prospective approaches, and the limited sample size within the study cohort. Conclusions Maternal BMI is a factor negatively influencing the efficacy of oral misoprostol for induction of labor in late-term pregnancy.

Advanced bipolar vessel sealing devices vs conventional bipolar energy in minimally invasive hysterectomy: a systematic review and meta-analysis

PURPOSE

To compare conventional bipolar electrosurgery with advanced bipolar vessel sealing (ABVS) devices for total laparoscopic hysterectomy (TLH).

METHODS

A systematic review was conducted by searching Scopus, PubMed/MEDLINE, ScienceDirect, and Cochrane Library from January 1989 to November 2021. We identified all studies comparing ABVS devices with conventional bipolar electrosurgery in TLH and reporting at least one of the following outcomes: total blood loss, total operative time, hospital stay, perioperative complications, or costs. Meta-analysis was conducted with a random effect model reporting pooled mean differences and odds ratios (ORs) with related 95% confidence intervals (CIs).

RESULTS

Two randomized controlled trials and two retrospective studies encompassing 314 patients were included out of 615 manuscripts. The pooled estimated total blood loss in the ABVS devices group was lower than conventional bipolar electrosurgery of 39 mL (95% CI - 65.8 to - 12.6 mL; p = .004). The use of ABVS devices significantly reduced the total operative time by 8 min (95% CI - 16.7 to - 0.8 min; p = .033). Hospital stay length did not differ between the two groups, and a comparable overall surgical complication rate was observed [OR of 0.9 (95% CI 0.256 - 3.200; p = .878].

CONCLUSIONS

High-quality evidence comparing ABVS devices with conventional bipolar electrosurgery for TLH is lacking. ABVS devices were associated with reduced total blood loss and operative time; however, observed differences seem clinically irrelevant. Further research is required to clarify the advantages of ABVS devices over conventional bipolar electrosurgery and to identify cases that may benefit more from their use.

SUrgical Access and Pattern of Recurrence of Endometrial Cancer: The SUPeR Study, a Multicenter Retrospective Observational Study

STUDY OBJECTIVE

To evaluate recurrence rate and pattern in apparently early-stage endometrial cancer (EC) treated with minimally invasive surgery (MIS) and compare it to the "historical" populations treated by laparotomy. Secondary outcomes were to establish if, among MIS recurrent patients, intermediate-high/high-risk patients presented the same recurrence pattern compared to those at low/intermediate-risk and to evaluate time to first recurrence (TTR) of the study population.

DESIGN

Multicenter retrospective observational study.

SETTING

Five Italian Gynecologic Oncology referral centers.

PATIENTS

All patients with proven recurrence of apparently early-stage EC treated with MIS from January 2017 to June 2022 . The laparotomic historical cohort was obtained from Laparoscopy Compared With Laparotomy for Comprehensive Surgical Staging of Uterine Cancer: Gynecologic Oncology Group Study (LAP2) and Laparoscopic Approach to Cancer of the Endometrium trials.

INTERVENTIONS

Evaluation of recurrence rate and pattern.

MEASUREMENTS AND MAIN RESULTS

Seventy-seven recurrences occurred on the total of 1028 patients treated with MIS for apparently early-stage EC during a median follow-up time of 36 months. The rate of recurrence in our cohort did not differ significantly from the rate of the historical cohort (7.4% vs 7.9%, odds ratio 0.9395, 95% CI 0.6901-1.2792). No significant differences were noticed for local, abdominal, nodal, and multiple site recurrence patterns; distant site recurrence appeared more likely in patients from the historical cohort. Postoperative low/intermediate risk patients had a higher likelihood of local recurrence compared to intermediate-high/high risk patients. Mean TTR was 19 months. No significant difference of TTR was observed for each pattern of recurrence compared to others.

CONCLUSION

MIS appears to be safe for the treatment of early-stage EC. We did not identify any recurrence pattern specifically associated with MIS in early-stage EC.

New neovagina-creating technique on the basis of a fasciocutaneous flap for Müllerian agenesis

BACKGROUND

Müllerian agenesis, known as Mayer-Rokitansky-Küster-Hauser syndrome, is characterized by the absence of the uterus, cervix, and two thirds of the proximal vagina. To allow sexual intercourse, dilatator-based conservative approaches and Vecchietti vaginoplasty generate progressive traction on the vaginal stump until adequate vaginal size is achieved. Other approaches create the neovagina using mucous/cutaneous, peritoneal, or ileal/sigmoid grafts or cutaneous flaps from the genitalia to fulfill a newly developed space between the bladder and rectum. The drawback of the first approach is the long time required, whereas stenosis, dehiscence, poor esthetic results, or absence of vaginal sensitivity limit the latter.

OBJECTIVE

To present a new surgical technique on the basis of an internal thigh fasciocutaneous flap for generating a compliant and sensitive neovagina with preservation of the external genitalia.

DESIGN

Video demonstration of the surgical steps.

PATIENT(S)

An 18-year-old woman with Müllerian agenesis confirmed at ultrasound and magnetic resonance imaging. The residual vagina was 3 cm long and 1.5 cm wide. After counseling by a gynecologist and plastic surgeon, in which all available techniques with pros and cons were exposed, the patient opted for the new technique. The long time required by conservative approaches and the desire to preserve the external genitalia with the chance to have a sensitive vagina guided the choice.

INTERVENTION(S)

The cul-de-sac of the vaginal stump was incised transversally. A 4-cm-wide and 9-cm-long canal bounded anteriorly by the bladder, posteriorly by the rectum, and superiorly by the peritoneum of Douglas was developed by blunt dissection. Fasciocutaneous flaps of 12 per 5 cm on the anteromedial aspect of the thighs were developed, identifying the vascular-from the pudendal artery-and nervous pedicles. A tunnel between the flap pedicles and neovagina introitus was created between fascia and subcutaneous tissue, detaching the vulvar structures from the ischiopubic ramus. Flaps were tunneled up to the neovagina introitus and sutured together by interrupted suture to form a tube with outside skin. The flaps were transposed into the canal everting the tube to obtain the skin lining the internal neovagina. The inferior margins of the flaps were sutured to the vaginal stump mucosa. No internal stitches were placed. Antibiotic prophylaxis was used during surgery. The entire procedure lasted 6 hours. During the postoperative period, no special positioning or ambulation restrictions were used.

MAIN OUTCOME MEASURE(S)

Compliance and sensitivity of the neovagina, esthetic result, and perioperative and long-term complications.

RESULT(S)

The postoperative course was uneventful, with early mobilization. The length of hospital stay was 16 days to allow proper vaginal dilator use; initial daily followed by intermittent use was planned. At a 2-year follow-up, the neovagina was sensitive and patent, allowing sexual intercourse. No complications were reported, and the patient was satisfied with the functional and esthetic result.

CONCLUSION(S)

The new surgical technique was feasible and effective, preserving the external genitalia and avoiding graft healing and bowel secretion drawbacks without an intra-abdominal surgical step and related risks. However, more cases-2 cases performed to date with similar results-and long-term follow-up are needed to confirm the efficacy. In this regard, the regular use of vaginal dilators and forecast adherence between flaps and the connective tissue of the bladder and rectum are expected to prevent neovagina prolapse without any anchoring to the pelvic structures.

Assessment of sentinel Lymph node mapping with different volumes of Indocyanine green in early-stage ENdometrial cancer: the ALIEN study

OBJECTIVE

To evaluate the impact of different volumes of indocyanine green (ICG) on the detection rate and bilateral mapping of sentinel lymph nodes in patients with apparent uterine-confined endometrial cancer.

METHODS

All patients who underwent surgical staging with sentinel node mapping in six reference centers were included. Two different protocols of ICG intracervical injection were used: (1) 2 mL group: total volume of 2 mL injected superficially; (2) 4 mL group: total volume of 4 mL, 2 mL deeply and 2 mL superficially. Logistic regression was used to analyze factors that could influence dye migration and detection rates. A sensitivity analysis was carried out to determine how independent variables could affect the sentinel node detection rate.

RESULTS

Of 442 eligible patients, 352 were analyzed (172 in the 2 mL group and 180 in the 4 mL group). The bilateral detection rates of the 2 mL and 4 mL groups were 84.9% and 86.1%, respectively (p=0.76). The overall detection rate was higher with a volume of 4 mL than with 2 mL (97.8% vs 92.4%, respectively; p=0.024). In the univariate analysis the rate of bilateral mapping fell from 87.5% to 73.5% when the International Federation of Gynecology and Obstetrics (FIGO) 2009 tumor stage was >IB (p=0.018). In the multivariate analysis, for both overall and bilateral detection rates a statistically significant difference emerged for the volume of ICG injected and FIGO 2009 stage >IB. Increasing body mass index was associated with worse overall detection rates on univariate analysis (p=0.0006), and significantly decreased from 97% to 91% when the body mass index exceeded 30 kg/m2 (p=0.05).

CONCLUSIONS

In patients with early-stage endometrial cancer, a volume of 2 mL ICG does not seem to compromise the bilateral detection of sentinel lymph nodes. In women with obesity and FIGO 2009 stage >IB, a 4 mL injection should be preferred.

Transvaginal Sonography for the Preoperative Assessment of Parametrial Deep Infiltrating Endometriosis: A Diagnostic Accuracy Study

OBJECTIVE

The aim of the study was to evaluate the diagnostic accuracy for parametria endometriosis (PE) of transvaginal sonography (TVS) performed following a systematic approach for the assessment of the lateral parametria.

DESIGN

A diagnostic accuracy study was employed based on a prospective observational design.

PARTICIPANTS

All consecutive patients who underwent laparoscopic surgery for endometriosis between January 2016 and December 2020 were considered.

SETTING

The study was conducted at endometriosis referral hospitals.

METHODS

We prospectively collected clinical, imaging, and surgical data of all consecutive patients who underwent laparoscopic surgery for endometriosis between January 2016 and December 2020. A standardized technique with a systematic approach for the assessment of the lateral parametria following specific anatomic landmarks was used for the TVS. The diagnostic accuracy for PE in TVS was assessed using the intraoperative and pathologic diagnosis of PE as the gold standard.

RESULTS

In 476 patients who underwent surgery, PE was identified in 114 out of 476 patients (23.95%): 91 left and 54 right PE out of 476 surgical procedures were identified (19.12% vs. 11.34%; p = 0.001); bilateral involvement in 27.19% (31/114 patients) cases. The sensitivity of TVS for PE was 90.74% (79.70-96.92%, 95% CI) for the right side and 87.91% (79.40-93.81%, 95% CI) for the left side. The specificity was almost identical for both sides (98.58% vs. 98.18%). For the right parametrium, the positive likelihood ratio (PLR) and negative likelihood ratio (NLR) were 63.82 (28.70-141.90, 95% CI) and 0.09 (0.04-0.22, 95% CI), respectively. On the left parametrium, the PLR and NLR were 48.35 (23.12-101.4, 95% CI) and 0.12 (0.07-0.21, 95% CI), respectively. The diagnostic accuracy for right and left PE was 97.69% (95.90-98.84%, 95% CI) and 96.22% (94.04-97.74%, 95% CI), respectively.

LIMITATIONS

The principal limit is the high dependence of TVS on the operator experience. Therefore, although a standardized approach following precise definitions of anatomical landmarks was used, we cannot conclude that the observed accuracy of TVS for PE is the same for all sonographers. In this regard, the learning curve was not assessed. In the case of negative TVS for parametrial involvement with an absent intraoperative suspect, a complete dissection of the parametrium was not performed to avoid surgical complications; therefore, cases of minor PE may be missed, underestimating false negatives.

CONCLUSIONS

TVS performed following a systematic approach for assessing the lateral parametria seems to have good diagnostic accuracy for PE with large changes in the posttest probability of parametrial involvement based on the TVS evaluation. Considering the clinical and surgical implications of PE, further studies implementing a standardized approach for assessing the parametrium by TVS are recommended to confirm our observations and implement a standardized protocol in clinical practice.

Intrauterine manipulator during hysterectomy for endometrial cancer: a systematic review and meta-analysis of oncologic outcomes

OBJECTIVE

This study aimed to assess the effects on oncologic outcomes of intrauterine manipulator use during laparoscopic hysterectomy for endometrial cancer.

DATA SOURCES

A systematic literature search was performed by an expert librarian in multiple electronic databases from inception to January 31, 2023.

STUDY ELIGIBILITY CRITERIA

We included all studies in the English language that compared oncologic outcomes (recurrence-free, cause-specific, or overall survival) between endometrial cancer patients who underwent total laparoscopic or robotic hysterectomy for endometrial cancer with vs without the use of an intrauterine manipulator. Studies comparing only peritoneal cytology status or lymphovascular space invasion were summarized for completeness. No selection criteria were applied to the study design.

METHODS

Four reviewers independently reviewed studies for inclusion, assessed their risk of bias, and extracted data. Pooled hazard ratios with 95% confidence intervals were estimated for oncologic outcomes using the random effect model. Heterogeneity was quantified using the I2 tests. Publication bias was assessed by funnel plot and Egger test.

RESULTS

Out of 350 identified references, we included 2 randomized controlled trials and 12 observational studies for a total of 14 studies and 5,019 patients. The use of an intrauterine manipulator during hysterectomy for endometrial cancer was associated with a pooled hazard ratio for recurrence of 1.52 (95% confidence interval, 0.99-2.33; P=.05; I2=31%; chi square P value=.22). Pooled hazard ratio for recurrence was 1.48 (95% confidence interval, 0.25-8.76; P=.62; I2=67%; chi square P value=.08) when only randomized controlled trials were considered. Pooled hazard ratio for overall survival was 1.07 (95% confidence interval, 0.65-1.76; P=0.79; I2=44%; chi square P value=.17). The rate of positive peritoneal cytology or lymphovascular space invasion did not differ using an intrauterine manipulator.

CONCLUSION

Intrauterine manipulator use during hysterectomy for endometrial cancer was neither significantly associated with recurrence-free and overall survival nor with positive peritoneal cytology or lymphovascular space invasion, but further prospective studies are needed.

Clinician perspectives on hysterectomy versus uterine preservation in pelvic organ prolapse surgery: A systematic review and meta-analysis

BACKGROUND

Previous reviews on hysterectomy versus uterine-sparing surgery in pelvic organ prolapse (POP) repair did not consider that the open abdominal approach or transvaginal mesh use have been largely abandoned.

OBJECTIVES

To provide up-to-date evidence by examining only studies investigating techniques currently in use for POP repair.

SEARCH STRATEGY

MEDLINE and Embase databases were searched from inception to January 2023.

SELECTION CRITERIA

We included randomized and non-randomized studies comparing surgical procedures for POP with or without concomitant hysterectomy. Studies describing open abdominal approaches or transvaginal mesh implantation were excluded.

DATA COLLECTION AND ANALYSIS

A random effect meta-analysis was conducted on extracted data reporting pooled mean differences and odds ratios (OR) between groups with 95% confidence intervals (CI).

MAIN RESULTS

Thirty-eight studies were included. Hysterectomy and uterine-sparing procedures did not differ in reoperation rate (OR 0.93; 95% CI 0.74-1.17), intraoperative major (OR 1.34; 95% CI 0.79-2.26) and minor (OR 1.38; 95% CI 0.79-2.4) complications, postoperative major (OR 1.42; 95% CI 0.85-2.37) and minor (OR 1.18; 95% CI 0.9-1.53) complications, and objective (OR 1.38; 95% CI 0.92-2.07) or subjective (OR 1.23; 95% CI 0.8-1.88) success. Uterine preservation was associated with a shorter operative time (-22.7 min; 95% CI -16.92 to -28.51 min), shorter hospital stay (-0.35 days, 95% CI -0.04 to -0.65 days), and less blood loss (-61.7 mL; 95% CI -31.3 to -92.1 mL). When only studies using a laparoscopic approach for both arms were considered, no differences were observed in investigated outcomes between the two groups.

CONCLUSIONS

No major differences were observed in POP outcomes between procedures with and without concomitant hysterectomy. The decision to preserve or remove the uterus should be tailored on individual factors.

Sentinel-node biopsy in apparent early stage ovarian cancer: final results of a prospective multicentre study (SELLY)

AIM

To evaluate the sensitivity and specificity of sentinel-lymph-node mapping compared with the gold standard of systematic lymphadenectomy in detecting lymph node metastasis in apparent early stage ovarian cancer.

METHODS

Multicenter, prospective, phase II trial, conducted in seven centers from March 2018 to July 2022. Patients with presumed stage I-II epithelial ovarian cancer planned for surgical staging were eligible. Patients received injection of indocyanine green in the infundibulo-pelvic and, when feasible, utero-ovarian ligaments and sentinel lymph node biopsy followed by pelvic and para-aortic lymphadenectomy was performed. Histopathological examination of all nodes was performed including ultra-staging protocol for the sentinel lymph node.

RESULTS

174 patients were enrolled and 169 (97.1 %) received study interventions. 99 (58.6 %) patients had successful mapping of at least one sentinel lymph node and 15 (15.1 %) of them had positive nodes. Of these, 11 of 15 (73.3 %) had a correct identification of the disease in the sentinel lymph node; 7 of 11 (63.6 %) required ultra-staging protocol to detect nodal metastasis. Four (26.7 %) patients with node-positive disease had a negative sentinel-lymph-node (sensitivity 73.3 % and specificity 100.0 %).

CONCLUSIONS

In a multicenter setting, identifying sentinel-lymph nodes in apparent early stage epithelial ovarian cancer did not reach the expected sensitivity: 1 of 4 patients might have metastatic lymphatic disease unrecognized by sentinel-lymph-node biopsy. Nevertheless, 35.0 % of node positive patients was identified only thanks to ultra-staging protocol on sentinel-lymph-nodes.

Concurrent Endometrial Cancer in Women with Atypical Endometrial Hyperplasia: What Is the Predictive Value of Patient Characteristics?

BACKGROUND

The rate of concurrent endometrial cancer (EC) in atypical endometrial hyperplasia (AEH) can be as high as 40%. Some patient characteristics showed associations with this occurrence. However, their real predictive power with related validation has yet to be discovered. The present study aimed to assess the performance of various models based on patient characteristics in predicting EC in women with AEH.

METHODS

This is a retrospective multi-institutional study including women with AEH undergoing definitive surgery. The women were divided according to the final histology (EC vs. no-EC). The available cases were divided into a training and validation set. Using k-fold cross-validation, we built many predictive models, including regressions and artificial neural networks (ANN).

RESULTS

A total of 193/629 women (30.7%) showed EC at hysterectomy. A total of 26/193 (13.4%) women showed high-risk EC. Regression and ANN models showed a prediction performance with a mean area under the curve of 0.65 and 0.75 on the validation set, respectively. Among the best prediction models, the most recurrent patient characteristics were age, body mass index, Lynch syndrome, diabetes, and previous breast cancer. None of these independent variables showed associations with high-risk diseases in women with EC.

CONCLUSIONS

Patient characteristics did not show satisfactory performance in predicting EC in AEH. Risk stratification in AEH based mainly on patient characteristics may be clinically unsuitable.

"Things Have Changed"-Laparoscopic Cytoreduction for Advanced and Recurrent Ovarian Cancer: The Experience of a Referral Center on 108 Patients

OBJECTIVE

To report the feasibility of laparoscopic cytoreduction surgery for primary and recurrent ovarian cancer in a select group of patients.

METHODS

A retrospective analysis was conducted on a cohort of patients with FIGO stage IIIA-IV advanced ovarian cancer who underwent laparoscopic primary debulking surgery (PDS), interval debulking surgery (IDS), or secondary debulking surgery (SDS) between June 2008 and January 2020. The primary endpoint was achieving optimal cytoreduction, defined as residual tumor less than 1 cm. Secondary endpoints included evaluating surgical complications and long-term survival, assessed at three-month intervals during the initial two years and then every six months.

RESULTS

This study included a total of 108 patients, among whom, 40 underwent PDS, 44 underwent IDS, and 24 underwent SDS. Optimal cytoreduction rates were found to be 95.0%, 97.7%, and 95.8% for the PDS, ISD, and SDS groups, respectively. Early postoperative complications (<30 days from surgery) occurred in 19.2% of cases, with 7.4% of these cases requiring reintervention. One patient died following postoperative respiratory failure. Late postoperative complications (<30 days from surgery) occurred in 9.3% of cases, and they required surgical reintervention only in one case. After laparoscopic optimal cytoreduction with a median follow-up time of 25 months, the overall recurrence rates were 45.7%, 38.5%, and 39.3% for PDS, ISD, and SDS, respectively. The three-year overall survival rates were 84%, 66%, and 63%, respectively, while the three-year disease-free survival rates were 48%, 51%, and 71%, respectively.

CONCLUSIONS

Laparoscopic cytoreduction surgery is feasible for advanced ovarian cancer in carefully selected patients, resulting in high rates of optimal cytoreduction, satisfactory peri-operative morbidity, and encouraging survival outcomes. Future studies should focus on establishing standardized selection criteria and conducting well-designed investigations to further refine patient selection and evaluate long-term outcomes.

Major vessel resection for complete cytoreduction in primary advanced and recurrent ovarian malignancies: A case series and systematic review of the literature - pushing the boundaries in oncovascular surgery

INTRODUCTION

Oncovascular surgery (the removal of major blood vessels infiltrated by cancer) is challenging but can be key to achieve complete cytoreduction in patient with advanced ovarian cancer. The aim of this study was to review the literature on oncovascular surgery in ovarian cancer and to report the details of all the cases performed at our institution.

METHODS

We retrospectively reviewed the database of ovarian cancer patients who underwent debulking surgery at the Department of Obstetrics and Gynecology of Verona University between January 2021 and 2023. Patients with at least one major vessel resection during cytoreduction were identified. We then systematically review the literature searching Pubmed and Embase from inception to January 2023 to report all cases of surgery for ovarian cancer with concomitant major vessel resection.

RESULTS

Five patients with advanced/recurrent ovarian cancer underwent major vascular resection at our institution. Vascular involvement was preoperatively identified in all cases and no case of vascular resection was performed after accidental injury. The major vessels removed were the inferior vena cava (n = 2), the common iliac veins (n = 2), the external iliac arteries (n = 2), the left common iliac artery (n = 1), and the left external iliac vein (n = 1). All patients underwent other non-gynecological cytoreductive procedures prior to vessel removal and had R0 obtained. Three (60%) patients experienced one or more postoperative complications. The literature search identified a total of seven cases of major vessels resection in ovarian cancer surgery. A single or multiple major vessels were removed in two (28.6%) and five (72.4%) cases, respectively. All the seven patients underwent vascular reconstruction. Four (57.1%) patients reported postoperative complications. Overall, 66.7% of the 12 total identified patients were free from disease at the last follow-up [median 15.5 months (range 5-25)].

CONCLUSIONS

Oncovascular surgery is feasible in selected patients with ovarian cancer, provided that a multidisciplinary approach with customized care is available.

Prognostic factors in patients with endometrial cancer with isolated lymphatic recurrence

OBJECTIVE

To analyze the clinicopathological features and outcomes in patients with endometrial cancer with isolated lymphatic recurrence after lymphadenectomy, stratified by different isolated lymphatic recurrence sites and treatment approaches.

METHODS

We retrospectively reviewed all surgically treated patients with endometrial cancer, identifying those with recurrence. We defined primary isolated lymphatic recurrence as the first and unique evidence of recurrence in lymph node-bearing areas, without concomitant vaginal, hematogenous, or peritoneal recurrence. Isolated lymphatic recurrences were classified as pelvic, para-aortic, distant, or multiple sites. Our primary outcome was cause-specific survival after diagnosis of the recurrence.

RESULTS

Among 4216 patients with surgically staged endometrial cancer, we identified 66 (1.6%) women with isolated lymphatic recurrence. The overall median cause-specific survival for patients with isolated lymphatic recurrence was 24 months. Although cause-specific survival was not significantly different between the four isolated lymphatic recurrence groups (p=0.21), 7 of 15 (47%) patients with isolated lymphatic recurrence in the para-aortic area were long-term survivors. At multivariate Cox regression, the absence of lymphovascular space invasion and grade 1 histology in the primary tumor were significantly associated with improved cause-specific survival. In addition, patients with isolated lymphatic recurrence who underwent surgery for recurrence (with/without other associated therapies) had improved cause-specific survival compared with patients who did not undergo surgery, also after adjusting for age.

CONCLUSIONS

Low-grade histology and absence of lymphovascular space invasion in the primary tumor were predictors of improved prognosis in patients with endometrial cancer with isolated lymphatic recurrence. In addition, in this retrospective cohort, patients with isolated lymphatic recurrence who were selected for eradicative surgical treatment had improved cause-specific survival.

Feasibility and Surgical Outcomes of Hysteroscopic Myomectomy of FIGO Type 3 Myoma: A Systematic Review

The latest classification from the Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) has reclassified type 3 myomas, changing their classification from intramural to submucosal. While hysteroscopic myomectomy is considered the gold standard treatment for patients experiencing symptoms from submucosal myomas, there are currently no specific guidelines available for managing type 3 myomas, and the optimal surgical approach remains uncertain. Methods: The search for suitable articles published in English was carried out using the following databases (PROSPERO ID CRD42023418602): MEDLINE, EMBASE, Global Health, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register), Health Technology Assessment Database, Web of Science and search register. Only original studies reporting data on hysteroscopic myomectomy of type 3 myoma were considered eligible. The main outcomes investigated were the effectiveness and feasibility of hysteroscopic myomectomy and reproductive outcomes after surgical treatment. Results: Two hundred and sixty-one studies were screened and nineteen of these were read for eligibility. Three studies encompassing 56 patients in total were included. Among the overall population studied, three patients needed an additional procedure to completely remove the myoma and five cases of post-surgical synechiae were recorded. No complications were reported. Of 42 patients wishing for pregnancy, the cumulative live birth rates before and after the hysteroscopic myomectomy were 14.3% and 42.9%, respectively. Conclusions: Hysteroscopic myomectomy appears to be a safe and feasible approach. Nevertheless, data reported in the literature are extremely scarce and based on studies with few patients enrolled. New evidence is needed to assess the safety and effectiveness of hysteroscopic treatment for FIGO type 3 myomas.

Effect of maternal age and body mass index on induction of labor with oral misoprostol for premature rupture of membrane at term: A retrospective cross-sectional study

The aim of this study was to evaluate the effect of maternal age and body mass index (BMI) on induction of labor with oral misoprostol for premature rupture of membrane (PROM) at term. We have conducted retrospective cross-sectional study, including only term (37 weeks or more of gestation) PROM in healthy nulliparous women with a negative vaginal-rectal swab for group B streptococcus, a single cephalic fetus with normal birthweight, and uneventful pregnancy that were induced after 24 h from PROM. Ninety-one patients were included. According to the multivariate logistic regression, age and BMI odds ratio (OR) for induction success were 0.795 and 0.857, respectively. The study population was divided into two groups based on age (<35 and ≥35 years) and obesity (BMI <30 and ≥30). Older women reported a higher induction failure rate (p < 0.001); longer time to cervical dilation of 6 cm (p = 0.03) and delivery (p < 0.001). Obese women reported a higher induction failure rate (p = 0.01); number of misoprostol doses (p = 0.03), longer time of induction (p = 0.03) to cervical dilatation of 6 cm (p < 0.001), and delivery (p < 0.001); and higher cesarean section (p = 0.012) and episiotomy rate (p = 0.007). In conclusion, maternal age and BMI are two of the main factors that influence oral misoprostol efficacy and affect the failure of induction rate in term PROM.

COVID-19 and Pregnancy: An Updated Review about Evidence-Based Therapeutic Strategies

The COVID-19 pandemic posed a significant challenge for clinicians in managing pregnant women, who were at high risk of virus transmission and severe illness. While the WHO declared in May 2023 that COVID-19 is no longer a public health emergency, it emphasized that it remains a global health threat. Despite the success of vaccines, the possibility of new pandemic waves due to viral mutations should be considered. Ongoing assessment of the safety and effectiveness of pharmacological therapies is crucial in clinical practice. This narrative review summarizes the evidence-based therapeutic strategies for pregnant women with COVID-19, considering over three years of pandemic experience. The review discusses the safety and effectiveness of various drug regimens (antivirals, anticoagulants, corticosteroids, immunoglobulins, monoclonal antibodies, and therapeutic gases) and procedures (prone positioning and extracorporeal membrane oxygenation). Drugs with contraindications, inefficacy during pregnancy, or unknown adverse effects were excluded from our evaluation. The aim is to provide healthcare professionals with a comprehensive guide for managing pregnant women with COVID-19 based on lessons learned from the pandemic outbreak.

The Role of Micronutrients in Human Papillomavirus Infection, Cervical Dysplasia, and Neoplasm

There is evidence that diet and nutrition are modifiable risk factors for several cancers. In recent years, attention paid to micronutrients in gynecology has increased, especially regarding Human papillomavirus (HPV) infection. We performed a review of the literature up until December 2022, aiming to clarify the effects of micronutrients, minerals, and vitamins on the history of HPV infection and the development of cervical cancer. We included studies having as their primary objective the evaluation of dietary supplements, in particular calcium; zinc; iron; selenium; carotenoids; and vitamins A, B12, C, D, E, and K. Different oligo-elements and micronutrients demonstrated a potential protective role against cervical cancer by intervening in different stages of the natural history of HPV infection, development of cervical dysplasia, and invasive disease. Healthcare providers should be aware of and incorporate the literature evidence in counseling, although the low quality of evidence provided by available studies recommends further well-designed investigations to give clear indications for clinical practice.

Primary cutaneous interdigitating dendritic cell sarcoma (IDCS): Report of a new case and literature review

Interdigitating dendritic cell sarcoma is a very rare entity in the spectrum of histiocytic and dendritic cell neoplasms that mostly occurs in lymph nodes, generally presenting as solitary lymphadenopathy, but may affect every organ. Among extra nodal sites, cutaneous interdigitating dendritic cell sarcoma is exceedingly rare; to date, only 9 cases have been described in English literature. The mean age at diagnosis was 60 years, with a male-female ratio of 1,5 to 1; clinically, two different modalities of skin presentation have been reported: solitary, represented by a single red-brownish nodular lesion, or diffuse, characterized by multiple nodular lesions in one or more body districts. The extreme rarity of this sarcoma and its morphological similarity to other poorly differentiated tumors may lead to a delay in diagnosis; in particular, cutaneous localization may be difficult to differentiate from follicular dendritic cell sarcoma, Langerhans cell sarcoma, poorly differentiated squamous cell carcinoma and more generally sarcomatoid carcinoma, atypical fibroxanthoma, malignant melanoma and several sarcomas. Immunohistochemistry plays an important role in identifying this rare entity and formulating a correct histological diagnosis, fundamental requirement for choosing the best therapeutic approach. We report herein a further case of an 81-year-old Caucasian woman who presented to the Dermatology Department to remove an asymptomatic skin papule in the left temporal region, clinically diagnosed as dermatofibroma. The overall pathological and immunohistochemical features supported the diagnosis of a malignant dendritic cell tumor, consistent of interdigitating dendritic cell sarcoma.

Neonatal Outcomes of Water Delivery versus Land Delivery: A Retrospective Propensity Score Weighted Study

OBJECTIVE

 Recent evidence has shown that water delivery is safe for the mother, but high-quality evidence is not available for the newborn. Therefore, obstetric guidelines do not support it. This retrospective study aimed to contribute to the available evidence on maternal and neonatal outcomes associated with water delivery.

STUDY DESIGN

 Retrospective cohort study from prospectively collected birth registry data from 2015 to 2019. A total of 144 consecutive water deliveries and 265 land deliveries eligible for waterbirth were identified. The inverse probability of treatment weighting (IPTW) method was applied to address for confounders.

RESULTS

 We identified 144 women who delivered in water (water group) and 265 women who delivered on land (land group). One (0.7%) neonatal death was observed in the water delivery group. After IPTW adjustment, water delivery was significantly associated with a higher risk of maternal fever in puerperium (odds ratio [OR]: 4.98; 95% confidence interval [CI]: 1.86-17.02; p = 0.004), of neonatal cord avulsion (OR: 20.73; 95% CI: 2.63-2,674; p = 0.001), and of positive neonatal C-reactive protein (CRP > 5 mg/L; OR: 2.59; 95% CI: 1.05-7.24; p = 0.039); delivering in water was associated with lower maternal blood loss (mean difference: 110.40 mL; 95% CI: 191.01-29.78; p = 0.007), a lower risk of major (≥1,000 mL) postpartum hemorrhage (OR: 0.96; 95% CI: 0.92-0.99; p = 0.016), lower risk of manual placenta delivery (OR: 0.18; 95% CI: 0.03-0.67; p = 0.008) and curettage (OR: 0.24; 95% CI: 0.08-0.60; p = 0.002), lower use of episiotomy (OR: 0.02; 95% CI: 0-0.12; p < 0.001), and lower risk of neonatal ward admission (OR: 0.35; 95% CI: 0.25-0.48; p < 0.001).

CONCLUSION

 The present study showed that differences are present between water and land delivery, and among them is the risk of cord avulsion, a severe and potentially fatal event. In women choosing to deliver in water, a trained staffmust be present and immediate recognition of cord avulsion is key for a prompt management to avoid possible serious complications.

KEY POINTS

· High-quality evidence is not available for neonatal safety of waterbirth; therefore, retrospective studies still represent the main body of evidence.. · Differences are present between water and land delivery, and among them, the increased risk of cord avulsion is a potentially fatal event.. · A trained staff must assist women who chose to deliver in water and cord avulsion must be promptly recognized and managed to avoid severe neonatal complications..

Do Exophytic and Endophytic Patterns in Borderline Ovarian Tumors Have Different Prognostic Implications? A Large Multicentric Experience

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.

Effects of neuraxial analgesia technique on labor and maternal-fetal outcomes: a retrospective study

PURPOSE

To compare the effects of epidural analgesia (EA) and combined spinal epidural analgesia (SEA) on labor and maternal-fetal outcomes.

METHODS

We retrospectively identified and included 1499 patients with a single cephalic fetus who delivered at the study center from January 2015 to December 2018 and received neuraxial analgesia at the beginning of the active phase of labor (presence of regular painful contractions and cervical dilatation between 4 and 6 cm). Data including analgesia, labor characteristics, and maternal-fetal outcomes were retrieved from the prospectively collected delivery room database and medical records.

RESULTS

SEA was associated with a shorter first stage of labor than EA, with a median difference of 60 min. On multivariable ordinal logistic regression analysis, neuraxial analgesia, gestational age, fetal weight, labor induction, and parity were independently associated with the first stage length: patients in the EA group were 1.32 times more likely to have a longer first stage of labor (95% CI 1.06-1.64, p = 0.012) than those in the SEA group. Additionally, a significantly lower incidence of fundal pressure was performed among patients who underwent SEA (OR 0.55, 95% CI 0.34-0.9, p = 0.017). No associations were observed between the used neuraxial analgesia technique and other outcomes.

CONCLUSIONS

SEA was associated with a shorter length of the first stage of labor and a lower rate of fundal pressure use than EA. Further studies confirming the effects of SEA on labor management and clarifying differences in maternal-fetal outcomes will allow concluding about the superiority of one technique upon the other.

Surgical Outcomes and Complications of Laparoscopic Hysterectomy for Endometriosis: a multicentric cohort study

STUDY OBJECTIVE

To investigate the postoperative morbidity of laparoscopic hysterectomy (LH) for endometriosis/adenomyosis in terms of operative outcomes and complications.

DESIGN

Retrospective multicentric cohort study.

SETTING

Eight European minimally invasive referral centers.

PATIENTS

Data from 995 patients with pathologically confirmed endometriosis and/or adenomyosis who underwent LH without concomitant urological and/or gastroenterological procedures from January 2010 to December 2020.

INTERVENTIONS

Total laparoscopic hysterectomy.

MEASUREMENTS AND MAIN RESULTS

Demographic patients' characteristics, surgical outcomes, and intraoperative and postoperative complications were evaluated. We considered major postoperative surgical-related complications any grade 2 or more events (Clavien-Dindo score) that occurred within 30 days from surgery. Univariate analysis and multivariable models fit with logistic regression were used to estimate the adjusted odds ratio (OR) and corresponding 95% CI for major complications. Median age at surgery was 44 years (28-54) and about half of them (505, 50.7%) were on medical treatment (estro-progestins, progestin or GnRh-analogues) at the time of surgery. In association with LH, posterior adhesiolysis was performed in 387 (38,9%) cases and deep nodule resection in 302 (30,0%). Intraoperative complications occurred in 3% of the patients and major postoperative complications were registered in 93 (9.3%). The multivariable analysis showed an inverse correlation between the occurrence of Clavien-Dindo >2 complications and age (OR 0.94, 95%CI 0.90-0.99), while previous surgery for endometriosis (OR 1.62, 95%CI 1.01-2.60) and intraoperative complications (OR 6.49, 95%CI 2.65-16.87) were found as predictors of major events. Medical treatment at the time of surgery has emerged as a protective factor (OR 0.50, 95%CI 0.31-0.81).

CONCLUSION

LH for endometriosis/adenomyosis is associated with non-negligible morbidity. Knowing the factors associated with higher risks of complications might be used for risk stratification and could help clinicians during preoperative counseling. The administration of estro-progestin or progesterone preoperatively might reduce the risks of postoperative complications following surgery.

Successful laparoscopic surgical removal of a caesarean scar pregnancy (CSP) using temporary uterine artery ligation

STUDY OBJECTIVE

To demonstrate a laparoscopic technique to remove a scar pregnancy.

DESIGN

Stepwise demonstration of the surgical technique.

SETTING

Santa Croce and Carle Hospital, Cuneo.

INTERVENTION

Patient B.B. is a woman referred to our center for a suspected cesarean scar pregnancy (CSP) at 9 weeks gestation. CSP occurs approximately in 6% of all ectopic pregnancies. The estimated incidence is reported to be 1:1800 to 1:2500 in cesarean deliveries. Depending on its location, CSP can be categorized as either type 1, if the growth is in the uterine cavity, or type 2, if it expands toward the bladder and the abdominal cavity. If inadequately managed, it can lead to severe complications; most of them are hemorrhagic and can threaten the woman's life. There are several therapeutic approaches: local excision seems to be the most effective choice in type 2 CSP. In expert hands, the laparoscopic approach is perhaps the best surgical choice as tissue dissection, electrosurgical hemostasis, and vascular control can be effectively managed with minimal invasive access. Because severe intraoperative bleeding can occur, retroperitoneal vascular control is mandatory in this surgery. In type 1 CSP curettage, aspiration or hysteroscopic approach can be considered if the CSP is of small dimensions. A hysteroscopic approach can also be helpful in type 2 CSP during the laparoscopic removal, as intrauterine guidance. A potassium chloride local injection can be considered in a preoperative stage in the presence of a fetal heart rate. The systemic administration of methotrexate is usually ineffective as single agent, but it can be useful if administered as adjuvant therapy. Uterine artery embolization can be useful in an emergency setting to manage severe bleeding, but it can lead to complications in subsequent pregnancies and, more rarely, to premature ovarian failure. Considering poor bleeding at presentation, feasible dimensions, and the woman's desire for future pregnancy, ultrasound-guided aspiration and curettage was attempted. Because endouterine removal was incomplete, methotrexate injection was proposed as adjuvant therapy, but the administration was postponed as the patient tested positive for coronavirus disease 2019. A month later, beta-human chorionic gonadotropin level dropped from over 16 000 to 271 mU/mL, so an ultrasound and biochemical follow-up was performed. A month later, despite a low beta-human chorionic gonadotropin value, an increase in dimensions was observed at ultrasound, so surgical laparoscopic removal was offered. In this video article, laparoscopic removal of scar pregnancy is discussed in the following surgical steps: (1) Temporary closure of uterine arteries at the origin, using removable clips. (2) Retroperitoneal dissection to safely manage the scar pregnancy. (3) Dissection of the myometrial-pregnancy interface. (4) Double layer suture on the anterior uterine wall.

CONCLUSION

Laparoscopic surgical management is a very effective surgical approach to remove CSP. Knowledge of retroperitoneal dissection and vascular control is necessary to carry out this surgical intervention safely and effectively.

COVID-19 and Pregnancy: Have We Gotten through the Darkest Hour?

On December 2019, a new Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) was isolated and identified in Wuhan (China) [...].

Risk perception and affective state on work exhaustion in obstetrics during the COVID-19 pandemic

A multicenter cross-sectional survey study involving four Italian University Hospitals was performed to test the hypothesis that negative affect and positive affect (affective dimensions) mediate the association between risk perception (perceived risk of infection and death; cognitive dimensions) and the feeling of work exhaustion (WE) among obstetrics healthcare providers (HCPs) during the Coronavirus Disease 2019 (COVID-19) pandemic. Totally, 570 obstetrics HCPs were invited to complete the 104-item IPSICO survey in May 2020. A theoretical model built on the tested hypothesis was investigated by structural equation modelling. The model explained 32.2% of the WE variance. Only negative affect mediated the association between cognitive dimensions and WE and also the association between WE and psychological well-being before the pandemic, experiences of stressful events, female gender, and dysfunctional coping. Non-mediated associations with WE were observed for work perceived as a duty, experience of stressful events, support received by colleagues, and the shift strategy. Only previous psychological well-being, support by colleagues, and shift strategies were inversely associated with WE. Based on study results, monitoring negative than positive affect appears superior in predicting WE, with practical implications for planning psychological interventions in HCPs at the individual, interpersonal, and organizational levels.

Isolated tumour cells in a sentinel lymph node of apparent early-stage ovarian cancer: Ultrastaging of all other 27 lymph nodes

•

Sentinel node is a promising possibility for retroperitoneal lymphatic staging in apparently early ovarian cancer.

•

We describe a patient with Isolated tumor cells (ITCs) in one sentinel node with all the other nodes negative at ultrastaging.

•

It is likely that the technique of sentinel node in early ovarian cancer is able to identify the real lymphatic drainage of the ovary.

•

This report represents a proof of concept in support of the use of sentinel node in apparently early ovarian cancer.

Sentinel lymph node (SLN) biopsy in apparent early-stage ovarian cancer may spare the surgical staging with extensive retroperitoneal dissection and its associated morbidity. However, SLN biopsy in ovarian cancer is still experimental and under investigation. A 46-year-old post-menopausal woman with bilateral apparent stage IC1 endometrioid ovarian cancer underwent surgical staging by SLN biopsy and subsequent comprehensive laparoscopic pelvic and para-aortic lymphadenectomy. Out of 4 SLNs submitted to ultrastaging, one was positive for isolated tumour cells (ITCs). We submitted to ultra-staging all the other 24 pelvic and para-aortic non-SLNs, which were reported negative for disease. This is the first reported case of comprehensive lymphadenectomy after SLN biopsy with universal ultrastaging of all non-SLNs in ovarian cancer. The presence of ITCs in only one SLN, with all other 27 lymph nodes negative at ultrastaging, is consistent with the SLN concept and the assumption of a reliable lymphatic pathway in ovarian cancer.

Female Sexual Dysfunctions and Urogynecological Complaints: A Narrative Review

Female sexual dysfunctions represent a real widespread problem, usually faced from a psychological point of view; however, millions of women worldwide are impacted by pelvic floor dysfunction, personal shame and social taboos, however, continue to inhibit free conversation on the subject. Women’s quality of life is considerably improved by screening, diagnosing, and controlling urogenital and sexual issues. This review aims to provide a critical perspective of urogenital conditions and common disturbances in female sexual function associated with these issues. It also includes a discussion of postpartum pelvic dysfunction.

Transvaginal versus port-site specimen retrieval after laparoscopic myomectomy: a systematic review and meta-analysis

INTRODUCTION

To date, there is no robust evidence suggesting whether transvaginal (TVSR) or port-site specimen retrieval (PSSR) after laparoscopic myomectomy (LM) may lead to better surgical outcomes. Considering this element, we aimed to compare surgical outcomes of TVSR versus PSSR after LM.

METHODS

A search (PROSPERO ID: CRD42020176490) of international databases, from 1980 to 2020, in English language, was conducted. We selected studies that included women who underwent LM with TVSR compared with PSSR.

RESULTS

We did not find significant differences for operative time (MD=-8.90 [95% CI -30.00, 12.20]; I2=87%), myoma retrieval time (MD=-1.85 [95% CI -13.55, 9.85]; I2=98%), blood loss (MD=-27.62 [95% CI -178.68, 124.43]; I2=91%), intra-operative complication rate (OR 0.51, 95% CI 0.01-23.09; I2=69%) and hospital stay (MD=-0.14 [95% CI -0.43; 0.15]; I2=64%); we found a significant lower post-operative rescue analgesics utilization in the TVSR group compared with the PSSR group (OR 0.31, 95% CI 0.16-0.61, I2=0).

CONCLUSION

TVSR and PSSR after LM showed comparable results for operative time and surgery-related complications. However, the need of post-operative rescue analgesics was lower in women who underwent TVSR.

See-and-treat in-office hysteroscopy versus operative hysteroscopy for the treatment of retained products of conception: A retrospective study

AIM

To compare the efficacy and safety of in-office hysteroscopy with a see-and-treat approach with that of operative hysteroscopy for the treatment of retained products of conception (RPOC).

METHODS

We retrospectively identified all consecutive patients who underwent hysteroscopic treatment of RPOC between 2015 and 2019. We excluded patients with RPOC larger than 2 cm at preoperative transvaginal ultrasounds. Between 2015 and 2017, all hysteroscopic removals of RPOC were performed by operative hysteroscopy. Between 2018 and 2019, all cases of RPOC less than 2 cm in size were hysteroscopically removed by the see-and-treat approach in the office setting. Sociodemographic, clinical, and procedure characteristics along with complications were retrieved from medical records.

RESULTS

Between 2015 and 2019, 119 women underwent hysteroscopic removal of RPOC equal to or smaller than 2 cm: 53 patients by in-office hysteroscopy, and 66 by operative hysteroscopy. The two groups were similar in preoperative characteristics. Although the time required to complete the RPOC removal was similar, the total procedure and assistant time were significantly higher in the operative hysteroscopy group (p < 0.001). Moreover, operative hysteroscopy was associated with a higher proportion of cases complicated by excessive bleeding, cervical tear, or uterine perforation (p = 0.016). Failure to complete the procedure was similarly reported in the two groups (p = 0.58).

CONCLUSIONS

In-office hysteroscopy with the see-and-treat approach for RPOC equal to or smaller than 2 cm appears as effective as operative hysteroscopy, but safer. In-office hysteroscopy may be considered the first choice for treating RPOC equal to or smaller than 2 cm.

Estrogeni e infiammazione

L’infiammazione è un processo essenziale per la vita, modulato da meccanismi immunoneuroendocrini. In questa Rassegna si analizza il ruolo degli estrogeni naturali umani (estradiolo, estrone, estriolo ed estetrolo) nella regolazione dell’infiammazione, facendo riferimento alla loro interazione con gli altri steroidi sessuali (progesterone e androgeni) nella modulazione di tale processo. L’infiammazione può essere fisiologica, quando è finalizzata (resolving), di breve durata, di intensità limitata e termina con restitutio ad integrum. È patologica quando perde tali caratteristiche diventando non finalizzata, non risolutiva (non resolving), di variabile intensità, con andamento cronico e progressiva distruzione tissutale. Durante la vita fertile della donna si manifestano tre eventi infiammatori fisiologici pertinenti alla sfera riproduttiva: l’ovulazione, la mestruazione e il parto. Tutti e tre sono strettamente correlati con le oscillazioni dei livelli di estrogeni, nonché del progesterone e degli androgeni. L’azione degli estrogeni nei confronti dell’infiammazione è molto articolata, in rapporto al tipo di estrogeno considerato, all’andamento dei suoi livelli plasmatici (fluttuante versus stabile) e al tipo di interazione con i recettori estrogenici, in particolare di tipo \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$\alpha $\end{document}α e \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$\beta $\end{document}β. Le fluttuazioni estrogeniche, in particolare dell’estradiolo, influiscono sulla presenza e l’attivazione delle varie classi di cellule immunitarie nell’endometrio e a livello sistemico. Accanto agli estrogeni, progesterone e androgeni rivestono un ruolo immunomodulatorio, con prevalenza anti-infiammatoria. La concisa descrizione delle complesse interazioni tra i diversi tipi di estrogeni e il sistema immunitario è stata fatta privilegiando gli aspetti più attinenti alla pratica clinica quotidiana dell’endocrinologo/a.

Cervical versus utero-ovarian ligament injection of the tracer for the pelvic sentinel lymph node mapping in gynecologic oncology: a prospective observational study

OBJECTIVE

In gynecologic oncology, the consolidated injection site for the pelvic sentinel lymph node mapping is the cervix. However, in apparent early-stage ovarian cancer, current trials map the pelvic area injecting the tracers in the utero-ovarian ligament. A different injection site is proposed based on a possible different lymphatic ovarian drainage through the utero-ovarian ligament and uterus and consequently a different pelvic sentinel lymph node mapping than the cervix; however, this was never proven. On that basis, this study aimed to investigate whether injecting the tracer in the utero-ovarian ligament map the same or a different pelvic sentinel lymph node than the cervix.

DESIGN

Prospective observational study.

METHODS

All consecutive women undergoing primary surgery for gynecologic malignancy with planned pelvic sentinel lymph node mapping were enrolled. The cervical injection was performed at 3 and 9 o'clock injecting indocyanine green. Bilateral utero-ovarian ligament injection was performed injecting methylene blue. The probability of detecting the same sentinel lymph node (concordance rate) and the probability of detecting a different sentinel lymph node (discordance rate) in each hemipelvis were compared using the McNemar's exact test.

RESULTS

Out of 36 hemipelvis (18 patients), the overall detection rate with cervical indocyanine green injection was 86.1% (31/36) versus 52.8% (19/36) with utero-ovarian ligament methylene blue injection (p=0.0004). Indocyanine green and methylene blue identified the same sentinel lymph node in all hemipelvis when sentinel lymph node mapping was obtained by both dyes (19/19; concordance rate 100%). No different or additional sentinel lymph nodes were identified by one of the two dyes (0/19; discordance rate 0%). The probability of detecting the same pelvic sentinel lymph node by the two injections sites was significantly higher than the probability of detecting a different pelvic sentinel lymph node (p<0.0001).

LIMITATIONS

The use of two different dyes with known different sentinel lymph node mapping performance impedes to evaluate differences in detection rate attributable to the two injection sites, limiting the comparison only in hemipelvis in which both dyes identified a sentinel lymph node.

CONCLUSIONS

Cervix and utero-ovarian ligament are two sites for the tracer injection that have a higher probability of detecting the same than a different pelvic sentinel lymph node. Given the higher technical challenge in performing the utero-ovarian ligament injection, these results suggest that the injection of the tracer into the cervix could be a more reliable alternative for the pelvic sentinel lymph node mapping in ovarian cancer.

Different Surgical Approaches for Early-Stage Ovarian Cancer Staging. A Large Monocentric Experience

Introduction

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 three different surgical approaches in a large series of patients.

Methods

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).

Results

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 approach.

SARS-CoV-2 detection in primary thyroid sarcoma: coincidence or interaction?

INTRODUCTION

Thyroid dysfunctions associated with SARS-CoV-2 are emerging in scientific literature. During the second COVID-19 epidemic spread, we evaluated a patient with the suspect of subacute thyroiditis.

METHODS AND RESULTS

Specimen from fine-needle aspiration of a hypoechoic undefined area was analyzed for cytology and for SARS-CoV-2 detection. SARS-CoV-2 was retrieved by real-time polymerase chain reaction on the cytologic sample, which was then cultured on Vero E6 cells and demonstrated to be cytopathic. Whole-genome sequence was deposited. Histological exam diagnosed a rare case of primary thyroid sarcoma with diffuse and strong expression of mouse double minute 2 homolog (MDM2) oncoprotein. Ultrastructural examination confirmed, in several neoplastic cells, the presence of viral particles in cytoplasmic vacuoles.

CONCLUSIONS

In our hypothesis, SARS-CoV-2 and sarcoma coexistence could represent a synergistic interplay, ultimately favoring both viral persistence and tumor proliferation: the overexpression of MDM2 in tumor cells might have generated a favorable immunological niche for SARS-CoV-2 localization and, in turn, SARS-CoV-2 could have favored tumor growth by inducing MDM2-mediated p53 downregulation. Functional studies are needed to confirm this suggestive pathway.

Psychological Impact of the Very Early Beginning of the COVID-19 Outbreak in Healthcare Workers: A Bayesian Study on the Italian and Swiss Perspectives

Background

We investigated the COVID19-related psychological impact on healthcare workers in Italy and in Italian-speaking regions of Switzerland, three weeks after its outbreak. All professional groups of public hospitals in Italy and Switzerland were asked to complete a 38 questions online survey investigating demographic, marital and working status, presence of stress symptoms and need for psychological support.

Results

Within 38 h a total of 3,038 responses were collected. The subgroup analysis identified specific categories at risk according to age, type of work and region of origin. Critical care workers, in particular females, reported an increased number of working hours, decline in confidence in the future, presence of stress symptoms and need for psychological support. Respondents reporting stress symptoms and those with children declared a higher need for psychological support.

Conclusions

The large number of participants in such a short time indicates for a high interest on topic among health-care workers. The COVID19 outbreak has been experienced as a repeated trauma for many health-care professionals, especially among female nurses' categories. Early evidence of the need of implementating short and long-term measures to mitigate impact of the emotional burden of COVID-19 pandemic are still relevant.

Left External Iliac Vein Injury During Laparoscopic Pelvic Lymphadenectomy for Early-Stage Ovarian Cancer: Our Experience and Review of Literature

Laparoscopic surgical staging is the standard treatment of early-stage ovarian tumors with similar survival outcomes if compared with laparotomic procedures. In this article, we report a case regarding an incidental external iliac vein injury during a pelvic lymphadenectomy for fertility sparing treatment of early-stage ovarian cancer with a video showing the laparoscopic repair without any consequence or side effect. A 36 year-old obese woman with Body Mass Index 30 kg/m² referred at our hospital with an histological diagnosis of high grade ovarian serous carcinoma after a left laparoscopic salpingo-oophorectomy performed in another hospital. After an hysteroscopy with endometrial biopsy, a laparoscopic surgical staging with a pelvic and aortic lymphadenectomy with lymph-node dissection until the left renal vein, omentectomy, and appendectomy were performed. A thermal injury to the left external iliac vein occurred using the bipolar forceps during lymphadenectomy and was repaired after an immediate clamping of the site using endoclinch and the suction irrigator probe. The laceration on the iliac vein was successfully repaired using 10 mm laparoscopic titanium clips; after a follow-up of 42 months no recurrence was detected. In conclusion, laparoscopy is a safe and effective therapeutic option for fertility sparing treatment patients with early stage ovarian carcinoma with a significantly low morbidity and postoperative hospitalization, but it should be reserved for oncologic surgeons trained in advanced laparoscopic procedures and repair of vascular injuries potentially associated with high mortality rate.

CO2-Laser therapy and Genitourinary Syndrome of Menopause: A Systematic Review and Meta-Analysis

BACKGROUND

Genitourinary syndrome of menopause (GSM) is a widespread condition with a great impact on quality of life and self-image.

AIM

We aimed to systematically review the current literature on CO2-Laser therapy efficacy for the treatment of GSM.

METHODS

MEDLINE and Embase databases were systematically queried in December 2020 Studies included women with a diagnosis of Vulvo-Vaginal Atrophy (VVA) or GSM without an history of gynaecological and/or breast cancer, pelvic organ prolapse staged higher than 2, pelvic radiotherapy or Sjogren's Syndrome. The quality of the evidence was assessed with the Cochrane risk of bias tool. This study is registered on PROSPERO, number CRD42021238121.

OUTCOMES

Effects of CO2-Laser therapy on GSM symptoms assessed through subjective or objective efficacy measurement methods.

RESULTS

A total of 803 articles were identified. Of these, 25 studies were included in this review for a total of 1,152 patients. All studies showed a significant reduction in VVA and/or GSM symptoms (dryness, dyspareunia, itching, burning, dysuria). The pooled mean differences for the symptoms were: dryness -5.15 (95% CI:-5.72,-4.58; P < .001; I2:62%; n = 296), dyspareunia -5.27 (95% CI:-5.93,-4.62; P < .001; I2:68%; n = 296), itching -2.75 (95% CI:-4.0,-1.51; P < .001; I2:93%; n = 281), burning -2.66 (95% CI:-3.75, -1.57; P < .001; I2:86%; n = 296) and dysuria -2.14 (95% CI:-3.41,-0.87; P < .001; I2:95%; n = 281). FSFI, WHIS and VMV scores also improved significantly. The pooled mean differences for these scores were: FSFI 10.8 (95% CI:8.41,13.37; P < .001; I2:84%; n = 273), WHIS 8.29 (95% CI:6.16,10.42; P < .001; I2:95%; n = 262) and VMV 30.4 (95% CI:22.38,38.55; P < .001; I2:24%; n = 68). CO2-Laser application showed a beneficial safety profile and no major adverse events were reported.

CLINICAL IMPLICATIONS

Vaginal laser treatment resulted in both a statistically and clinically significant improvement in GSM symptoms. FSFI improved significantly in all 8 included studies but it reached a clinically relevant level only in 2 of them.

STRENGTHS & LIMITATIONS

The strength of the current meta-analysis is the comprehensive literature search. We reported data from a high number of patients (1,152) and high number of laser applications (more than 3,800). The main limitations are related to the high heterogeneity of the included studies investigating laser effects. Moreover, most of them are single center and nonrandomized studies.

CONCLUSION

The data suggest that CO2-Laser is a safe energy-based therapeutic option for the management of VVA and/or GSM symptoms in postmenopausal women; however, the quality of the body of evidence is "very low" or "low".

Prevalence of intrauterine adhesions after myomectomy: a prospective multicenter observational study

OBJECTIVES

To evaluate intrauterine adhesion formation after laparoscopic and laparotomic myomectomy.

DESIGN

Prospective, multicenter, observational study (ClinicalTrials.gov ID: NCT04030273).

METHODS

We included patients after laparotomic and laparoscopic myomectomy. All patients underwent post-surgical diagnostic hysteroscopy, after three months. The intrauterine adhesion rate and associated factors were investigated.

RESULTS

Between January 2020 and December 2020, 38 and 24 consecutive patients underwent laparoscopic and laparotomic myomectomy, respectively. All diagnostic hysteroscopies were performed in the office setting without complications. Intrauterine adhesions were identified in 19.4% of women (95% CI of 9 - 29%). Factors univariately associated (p <0.2) with the presence of intrauterine adhesions after myomectomy were previous uterine surgery, the surgical approach (laparoscopic or laparotomic), the number of removed fibroids, the type and diameter of the largest myoma, and the opening of the uterine cavity. In the multivariable analysis, only the opening of the uterine cavity (OR 51.99; 95% CI, 4.53 - 596.28) and the laparotomic approach (OR, 16.19; 95% CI, 1.66 - 158.35) were independently associated with the identification of intrauterine adhesions after myomectomy.

LIMITATIONS

One of the main limitations of our study is that we used uterine manipulator only in laparoscopic group; in addition, we did not perform a pre-operative hysteroscopy to evaluate the rate of intrauterine adhesions potentially present even before the myomectomy.

CONCLUSIONS

The prevalence of intrauterine adhesions after three months from surgery was significantly associated with the opening of the uterine cavity and the laparotomic approach.
