It is time to implement molecular classification in endometrial cancer.

A huge effort has been done in redefining endometrial cancer (EC) risk classes in the last decade. However, known prognostic factors (FIGO staging and grading, biomolecular classification and ESMO-ESGO-ESTRO risk classes stratification) are not able to predict outcomes and especially recurrences. Biomolecular classification has helped in re-classifying patients for a more appropriate adjuvant treatment and clinical studies suggest that currently used molecular classification improves the risk assessment of women with EC, however, it does not clearly explain differences in recurrence profiles. Furthermore, a lack of evidence appears in EC guidelines. Here, we summarize the main concepts why molecular classification is not enough in the management of endometrial cancer, by highlighting some promising innovative examples in scientific literature studies with a clinical potential significant impact.

The role of L1CAM as predictor of poor prognosis in stage I endometrial cancer: a systematic review and meta-analysis.

INTRODUCTION: Molecular and genomic profiling in endometrial cancer is increasing popularity. L1 cell adhesion molecule (L1CAM) is frequently mutated in endometrial cancer. In this paper, we aim to evaluate the prognostic role of L1CAM in patients with stage I endometrial cancer. METHODS: We performed a systematic review and meta-analysis searching in PubMed (MEDLINE), EMBASE, and Web of Science database to identify studies reporting the expression of L1CAM in endometrial cancer. The primary endpoint measure was to assess and evaluate the impact of L1CAM on survival outcomes. This study was performed according to the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) statement. RESULTS: Five studies were included. The pooled results suggested that L1CAM expression influences survival outcomes in stage I endometrial cancer. High L1CAM expression correlated with worse disease-free survival (HR 4.11, 95% CI 1.02-16.59, p = 0.047) and overall survival (HR 3.62, 95% CI 1.32-9.31, p = 0.012). High L1CAM level was also associated with a more aggressive FIGO grade and with older age. CONCLUSION: This systematic review supported that L1CAM have a prognostic role in stage I endometrial cancer, thus providing a potential useful tool for tailoring the need of adjuvant therapy.

Can the Modified Frailty Index (mFI) Predict Intraoperative and Postoperative Complications in Older Women with Endometrial Cancer Undergoing Laparoscopic or Robotic Surgery? A Multicenter Observational Study.

BACKGROUND: This study aims to evaluate the strength of the association between frailty and intraoperative/postoperative complications in patients undergoing minimally invasive surgery (MIS) for endometrial cancer. METHODS: In this retrospective observational multicenter cohort study, frailty was defined beforehand by a modified frailty index (mFI) score of ≥3. Multiple logistic regressions were performed to investigate possible preoperative predictors-including frailty, age, and body mass index-of intraoperative and early (within 30 days from surgery) or delayed (beyond 30 days from surgery) postoperative complications. RESULTS: The study involved 577 women, of whom 6.9% (n = 40) were frail with an mFI ≥ 3, while 93.1% (n = 537) were non-frail with an mFI of 0-2. Frail women had a significantly higher rate of intraoperative complications (7.5% vs. 1.7%, p = 0.01), with odds 4.54 times greater (95% CI: 1.18-17.60, p = 0.028). There were no differences in the rate of early postoperative complications (15% vs. 6.9%, p = 0.06) and delayed postoperative complications (2.5% vs. 3.9%, p = 0.65) for frail versus non-frail patients. The odds of early postoperative complications increased by 0.7% (95% CI: 1.00-1.15) for every one-unit increase in age (p = 0.032). CONCLUSIONS: Frailty was associated with a significantly higher risk of intraoperative complications in older women undergoing MIS for endometrial cancer. Likewise, increasing age was an independent predictor of early postoperative complications. Our findings support the practice of assessing frailty before surgery to optimize perioperative management in this patient population.

Complement-Mediated Thrombotic Microangiopathy in Pregnancy: An Educational Case Report.

Rationale: Thrombotic microangiopathy (TMA) is a spectrum of rare diseases characterized by thrombocytopenia, microangiopathic hemolytic anemia, and organ damage. Differentiating pre-eclampsia, HELLP (Hemolysis, Elevated Liver enzymes, Low Platelets) syndrome and atypical hemolytic uremic syndrome (aHUS) during pregnancy may be diagnostically challenging yet important as the treatment pathways differ. Most cases of aHUS are associated with dysregulation of the complement alternative pathway, for which current guidelines recommend prompt treatment with complement C5 inhibitor to prevent chronic sequelae. Here, we report a case of pregnancy-associated aHUS (p-aHUS) to highlight the challenging aspects of the diagnostic process and the importance of prompt treatment with complement inhibition to reduce the risk of poor outcomes. Presenting concerns: A 28-year-old woman was admitted to a local hospital for induction of vaginal delivery of twins at 34 weeks and 3 days of gestational age, due to intrauterine growth restriction (IUGR). She was previously healthy, and this current pregnancy was uncomplicated, except for the IUGR. Approximately, 10 hours after her induced delivery, she developed vomiting, epigastric pain, and hypertension. Diagnosis: She was initially suspected of having fulminant liver failure in the context of acute fatty liver of pregnancy versus pre-eclampsia/HELLP syndrome, due to evidence of elevated liver enzymes, acute kidney injury (AKI), thrombocytopenia, and hemoglobin levels trending down, for which the patient was initially treated conservatively. On day 2 post-delivery, she was transferred to our hospital for possible liver biopsy and management of liver failure. Upon transfer, dialysis was started due to anuric AKI; at the same time, her liver function spontaneously improved, while platelet count remained very low and hemoglobin levels continued to trend down. A full TMA work-up revealed low C3 levels; secondary causes of TMA were ruled out. The patient received a final diagnosis of p-aHUS. Complement genetic tests were also performed and did not identify any pathogenic variants. Interventions: Given the final diagnosis of p-aHUS, the patient was started on a C5 inhibitor (day 8 post-delivery). Her platelet count quickly normalized 2 days after the first dose, while the hemoglobin levels remained low for a longer period, likely due to retained products of conception. Outcomes: The patient was able to completely discontinue dialysis after approximately 3 months, however, her kidney function did not recover completely, despite all the other TMA markers normalizing (platelets count in range, negative hemolysis markers, and normal hemoglobin levels). Her estimated glomerular filtration rate (eGFR) was 23 mL/min/1.73 m2 at the 6-month follow-up. Teaching points: The diagnosis of p-aHUS can be challenging due to frequent overlapping symptoms and signs with other forms of pregnancy-associated TMA, leading to a delay of the treatment, which can affect the patient's outcome. Failure of TMA to improve in the postpartum period or occurring at this time, with negative ADAMTS13 and antiphospholipid antibody syndrome (APLAS) serologies should favor the diagnosis of p-aHUS. Early treatment with C5 inhibition should be considered in women with a diagnosis of p-aHUS. Patients need multidisciplinary and likely tertiary/quaternary care at centers where clinical experience, access to diagnostics and treatment initiation can begin without delay.

Justification: La microangiopathie thrombotique (MAT) est un spectre de maladies rares caractérisées par une thrombocytopénie, une anémie hémolytique microangiopathique et des lésions à différents organes. Pendant la grossesse, il peut être difficile de différencier la prééclampsie, le syndrome HELLP (Haemolysis, Elevated Liver enzymes, Low Platelets) et le syndrome hémolytique et urémique atypique (SHUa) d'un point de vue diagnostique, mais il est important de le faire, car les avenues de traitement diffèrent. La plupart des cas de SHUa sont associés à un dérèglement de la voie alterne du complément, pour lequel la recommandation actuelle est de privilégier un traitement rapide avec un inhibiteur de la fraction C5 du complément afin de prévenir les séquelles chroniques. Dans le présent article, nous présentons un cas de SHUa associé à une grossesse (SHUa-g) afin de mettre en évidence les difficultés associées au diagnostic et l'importance de traiter rapidement par inhibition du complément afin de réduire le risque de résultats défavorables. Présentation du cas: Une femme de 28 ans admise dans un hôpital local pour l'induction d'un accouchement vaginal de jumeaux à 34 semaines et 3 jours, en raison d'un retard de croissance intra-utérin (RCIU). La patiente était en bonne santé et la grossesse, à l'exception du RCIU, était sans complications. Environ dix heures après l'accouchement, la patiente a développé des vomissements, des douleurs épigastriques et de l'hypertension. Diagnostic: On a d'abord soupçonné une insuffisance hépatique fulminante liée soit à une stéatose hépatique aiguë de la grossesse ou encore à une prééclampsie/syndrome HELLP, en raison d'une élévation des enzymes hépatiques, d'une insuffisance rénale aiguë, d'une thrombocytopénie et d'une baisse de l'hémoglobine, pour lesquelles la patiente a initialement été traitée de façon conservatrice. Deux jours après l'accouchement, la patiente a été transférée à notre hôpital pour une possible biopsie du foie et la prise en charge d'une insuffisance hépatique. Après le transfert, une IRA anurique a justifié l'initiation de la dialyse. Au même moment, la fonction hépatique s'est améliorée spontanément, tandis que la numération plaquettaire est demeurée très faible et que les taux d'hémoglobine ont continué à baisser. Un bilan MAT complet a révélé de faibles taux de C3; les causes secondaires de MAT ont été écartées. La patiente a reçu un diagnostic final de SHUa-g. Des tests génétiques complémentaires n'ont pas permis d'identifier de variants pathogènes. Intervention: Compte tenu du diagnostic final de SHUa-g, un traitement avec un inhibiteur de C5 a été amorcé (au huitième jour après l'accouchement). La numération plaquettaire s'est rapidement normalisée deux jours après la première dose, mais les taux d'hémoglobine sont demeurés bas sur une plus longue période, probablement en raison de la rétention de produits de la conception. Résultats: La patiente a pu cesser complètement la dialyse environ trois mois plus tard, mais sa fonction rénale ne s'est pas complètement rétablie, malgré la normalisation de tous les autres marqueurs de MAT (numération plaquettaire dans les normales, marqueurs d'hémolyse négatifs, taux d'hémoglobine normaux). Son débit de filtration glomérulaire estimé (DFGe) s'établissait à 23 ml/min/1.73 m2 lors du suivi à six mois. Enseignements tirés: Le chevauchement fréquent des symptômes et signes cliniques des autres formes de MAT associées à la grossesse rend parfois difficile le diagnostic du SHUa-g, ce qui peut retarder le traitement et affecter l'évolution clinique. L'absence d'amélioration d'une MAT dans la période postpartum, ou sa survenue à ce moment, couplée à des sérologies négatives pour ADAMTS13 et pour le syndrome des anticorps antiphospholipides (SAPL) devrait plaider en faveur d'un diagnostic de SHUa-g. Un traitement précoce par inhibition de C5 doit être envisagé chez les femmes qui reçoivent un diagnostic de SHUa-g. Ces patientes requièrent des soins multidisciplinaires, et probablement tertiaires/quaternaires, dans des centres où l'expérience clinique, l'accès au diagnostic et l'initiation du traitement sont rapidement accessibles.

Machine learning endometrial cancer risk prediction model: integrating guidelines of European Society for Medical Oncology with the tumor immune framework.

OBJECTIVE: Current prognostic factors for endometrial cancer are not sufficient to predict recurrence in early stages. Treatment choices are based on the prognostic factors included in the risk classes defined by the ESMO-ESGO-ESTRO (European Society for Medical Oncology-European Society of Gynaecological Oncology-European Society for Radiotherapy and Oncology) consensus conference with the new biomolecular classification based on POLE, TP53, and microsatellite instability status. However, a minority of early stage cases relapse regardless of their low risk profiles. Integration of the immune context status to existing molecular based models has not been fully evaluated. This study aims to investigate whether the integration of the immune landscape in the tumor microenvironment could improve clinical risk prediction models and allow better profiling of early stages. METHODS: Leveraging the potential of in silico deconvolution tools, we estimated the relative abundances of immune populations in public data and then applied feature selection methods to generate a machine learning based model for disease free survival probability prediction. RESULTS: We included information on International Federation of Gynecology and Obstetrics (FIGO) stage, tumor mutational burden, microsatellite instability, POLEmut status, interferon γ signature, and relative abundances of monocytes, natural killer cells, and CD4+T cells to build a relapse prediction model and obtained a balanced accuracy of 69%. We further identified two novel early stage profiles that undergo different pathways of recurrence. CONCLUSION: This study presents an extension of current prognostic factors for endometrial cancer by exploiting machine learning models and deconvolution techniques on available public biomolecular data. Prospective clinical trials are advisable to validate the early stage stratification.

Shiga toxin targets the podocyte causing hemolytic uremic syndrome through endothelial complement activation.

BACKGROUND: Shiga toxin (Stx)-producing Escherichia coli hemolytic uremic syndrome (STEC-HUS) is the leading cause of acute kidney injury in children, with an associated mortality of up to 5%. The mechanisms underlying STEC-HUS and why the glomerular microvasculature is so susceptible to injury following systemic Stx infection are unclear. METHODS: Transgenic mice were engineered to express the Stx receptor (Gb3) exclusively in their kidney podocytes (Pod-Gb3) and challenged with systemic Stx. Human glomerular cell models and kidney biopsies from patients with STEC-HUS were also studied. FINDINGS: Stx-challenged Pod-Gb3 mice developed STEC-HUS. This was mediated by a reduction in podocyte vascular endothelial growth factor A (VEGF-A), which led to loss of glomerular endothelial cell (GEnC) glycocalyx, a reduction in GEnC inhibitory complement factor H binding, and local activation of the complement pathway. Early therapeutic inhibition of the terminal complement pathway with a C5 inhibitor rescued this podocyte-driven, Stx-induced HUS phenotype. CONCLUSIONS: This study potentially explains why systemic Stx exposure targets the glomerulus and supports the early use of terminal complement pathway inhibition in this devastating disease.

Urological Complications in Radical Surgery for Cervical Cancer: A Comparative Meta-Analysis before and after LACC Trial.

BACKGROUND: After the LACC trial publication in 2018, the minimally invasive approach (MIS) has severely decreased in favor of open surgery: MIS radical hysterectomy was associated with worse oncological outcomes than open surgery, but urological complications were never extensively explored in pre- versus post-LACC eras, even if they had a great impact on post-operative QoL. The purpose of this meta-analysis is to compare functional and organic urological complication rates before and after LACC trial. METHODS: An independent search of the literature was conducted 4 years before and after the LACC trial and 50 studies were included. RESULTS: The overall rate of urologic complications was higher in pre-LACC studies while no differences were found for organic urological complications. Conversely, the overall risk of dysfunctional urological complications showed a higher rate in the pre-LACC era. This is probably related to a sudden shift to open surgery, with potential lower thermal damage to the urinary tract autonomic nervous fibers. CONCLUSIONS: This meta-analysis showed that the incidence of urological complications in radical cervical cancer surgery was higher before the LACC trial, potentially due to the shift to open surgery. Nevertheless, further studies are needed to shed light on the connection between minimally invasive surgery and urological damage.

Sexual dysfunctions in breast cancer patients: evidence in context.

INTRODUCTION: In breast cancer patients, endocrine therapy may exert a negative impact on sexual functioning in both genders, with potentially relevant consequences concerning quality of life and treatment adherence. The availability of effective interventions to maintain and/or restore sexual health in breast cancer patients is a key issue to a research agenda. OBJECTIVES: To summarize and critically discuss the most updated and qualitatively relevant literature on the therapeutic approach to sexual impairment in breast cancer patients, with a focus on patients treated with endocrine therapy. METHODS: We searched PubMed from its inception to February 2022 for observational and intervention trials including participants with sexual dysfunctions. We were particularly interested in studies of breast cancer patients with sexual dysfunctions while undergoing endocrine therapy. We developed a search strategy with the aim of maximizing the number of articles considered for screening and potential inclusion. RESULTS: Forty-five studies were selected: 3 observational and 42 intervention studies. Thirty-five studies were exclusively focused on female breast cancer populations. We could not identify studies exclusively focused on or also including male breast cancer patients. Overall, in female patients, the available armamentarium encompasses vaginal lubricants, moisturizers, estrogens, dehydroepiandrosterone, CO2 laser, ospemifene, and counseling. None of these interventions has been demonstrated to completely solve sexual dysfunctions when singularly considered. More favorable outcomes have come from the combination of different therapies. CONCLUSION: In female breast cancer, future research is oriented toward the gain of evidence on combined therapies and long-term data on safety issues on the most promising interventions. The lack of evidence on sexual disturbances in male breast cancer patients remains a major concern.

Towards reproducible research in recurrent pregnancy loss immunology: Learning from cancer microenvironment deconvolution.

The most recent international guidelines regarding recurrent pregnancy loss (RPL) exclude most of the immunological tests recommended for RPL since they do not reach an evidence-based level. Comparisons for metanalysis and systematic reviews are limited by the ambiguity in terms of RPL definition, etiological and risk factors, diagnostic work-up, and treatments applied. Therefore, cohort heterogeneity, the inadequacy of numerosity, and the quality of data confirm a not standardized research quality in the RPL field, especially for immunological background, for which potential research application remains confined in a separate single biological layer. Innovative sequencing technologies and databases have proved to play a significant role in the exploration and validation of cancer research in the context of dataset quality and bioinformatics tools. In this article, we will investigate how bioinformatics tools born for large-scale cancer immunological research could revolutionize RPL immunological research but are limited by the nature of current RPL datasets.

Outpatient Hysteroscopic Polypectomy-A Retrospective Study Comparing Rigid and Semirigid Office Hysteroscopes.

Endometrial polyps are one of the most common pathological conditions in gynecology. Hysteroscopy is the gold standard for the diagnosis and treatment of endometrial polyps. The purpose of this multicenter, retrospective study was to compare patients' pain perception during an operative hysteroscopic endometrial polypectomy in an outpatient setting with two different hysteroscopes (rigid and semirigid) and to identify some clinical and intraoperative characteristics that are related to worsening pain during the procedure. We included women that underwent, at the same time as an diagnostic hysteroscopy, the complete removal of an endometrial polyp (using the see-and-treat strategy) without any kind of analgesia. A total of 166 patients were enrolled, of which 102 patients underwent a polypectomy with a semirigid hysteroscope and 64 patients underwent the procedure with a rigid hysteroscope. No differences were found during the diagnostic step; on the contrary, after the operative procedure, a statistically significant greater degree of pain was reported when the semirigid hysteroscope was used. Cervical stenosis and menopausal status were risk factors for pain both in the diagnostic step and in the operative one. Our results confirm that operative hysteroscopic endometrial polypectomy in an outpatient setting is an effective, safe, and well-tolerated procedure and indicate that it might be better tolerated if a rigid rather than semirigid instrument is used.

Beyond Sentinel Lymph Node: Outcomes of Indocyanine Green-Guided Pelvic Lymphadenectomy in Endometrial and Cervical Cancer.

BACKGROUND: The aim of our study was to compare the number of lymph nodes removed during indocyanine green (ICG)-guided laparoscopic/robotic pelvic lymphadenectomy with standard systematic lymphadenectomy in endometrial cancer (EC) and cervical cancer (CC). METHODS: This is a multicenter retrospective comparative study (Clinical Trial ID: NCT04246580; updated on 31 January 2023). Women affected by EC and CC who underwent laparoscopic/robotic systematic pelvic lymphadenectomy, with (cases) or without (controls) the use of ICG tracer injection within the uterine cervix, were included in the study. RESULTS: The two groups were homogeneous for age (p = 0.08), Body Mass Index, International Federation of Gynaecology and Obstetrics (FIGO) stages (p = 0.41 for EC; p = 0.17 for CC), median estimated blood loss (p = 0.76), median operative time (p = 0.59), and perioperative complications (p = 0.66). Nevertheless, the number of lymph nodes retrieved during surgery was significantly higher (p = 0.005) in the ICG group (n = 18) compared with controls (n = 16). CONCLUSIONS: The accurate and precise dissection achieved with the use of the ICG-guided procedure was associated with a higher number of lymph nodes removed in the case of systematic pelvic lymphadenectomy for EC and CC.

The giant cell tumor during pregnancy: A review of literature.

BACKGROUND: Giant cell tumors (GTC) of bone are benign, locally aggressive tumors generally occurring in young people with a female predominance during reproductive age. Considering their worsening during pregnancy it has been suggested that pregnancy can accelerate GCT progression or favor recurrence but correlation between tumor growth and pregnancy has not yet been clarified. Aim of this study was to clarify clinical characteristics, timing and type of treatment through a literature review on GTCs occurring during pregnancy. PATIENTS AND METHODS: An electronic search was performed in December 2020 in PubMed, Scopus, Embase, Medline, Cochrane Register using the keywords "giant cell tumor" AND "pregnancy" looking for papers reporting cases of giant cell tumors of the bone onset or recurred during pregnancy. The electronic search identified 212 papers; sixteen studies were selected, for a total of 32 cases. RESULTS: The diagnosis was made during pregnancy in 24 cases and after the partum in 8 cases. 27 cases were new diagnoses while 5 cases were recurrences. Pulmonary metastases were reported in 3 patients. The treatment was performed during the pregnancy in 7 out of 32 cases; in the remaining 27 cases treatment was performed after delivery. The hormone receptor status was reported in 14 patients. Data regarding follow-up was reported for 26 out of 32 patients; three patients had local recurrences that were treated with wide resection and amputation in 2 and 1 case, respectively; at the last follow-up all patients were apparently without any evidence of disease except for three patients who had stable lung metastases. DISCUSSION: In case of GCT during pregnancy, a multidisciplinary approach is necessary to offer the patients the best treatment in terms of mother and child's health. A correct diagnosis is necessary and not confusing tumor symptoms with ones of pregnancy is mandatory in order not to delay the diagnosis and let the tumor progress. Actually, even though pregnancy would seem to promote GCT growth and aggressiveness, the relationship is not clear. More studies are necessary to clarify this interesting aspect. LEVEL OF EVIDENCE: IV, systematic review.

Percutaneous-assisted laparoscopy for ovarian tissue cryopreservation: a single-center experience.

PURPOSE: To compare surgical and post-operative outcomes of patients submitted to traditional laparoscopy and percutaneous-assisted laparoscopy for ovarian tissue explant for cryopreservation. METHODS: This is a single-center retrospective comparative study conducted in IRCCS "Regina Elena" National Cancer Institute of Rome. Patients submitted to laparoscopic excision of ovarian tissue, before starting chemotherapy were enrolled. We compared the classic laparoscopic approach vs percutaneous-assisted laparoscopy, using the Percuvance grasping forceps. RESULTS: Fifty-nine young oncologic women were enrolled; 38 underwent a conventional laparoscopy (LAP), 21 received a percutaneous laparoscopy (PERC). The baseline characteristics were similar in both groups, furthermore no differences were found in terms of peri-operative complications, median estimated blood loss (p = 0.4), operative time (p = 0.2), recovery times (p = 0.1), median time to chemotherapy (p = 0.7), median area of collected samples (p = 0.9). The postoperative pain evaluated by VAS-score, was significantly lower in the PERC group vs LAP group, both the day of surgery (range 0-4 vs 0-2; p = 0.02) and after 1 (range 0-3 vs 0-2; p = 0.002) and 2 days (range 0-3 vs 0-1; p = 0.0001). Moreover, better aesthetic results were detected in the PERC group, 2 months after surgery (median 9 vs 10, range 7-10 vs 9-10; p = 0.0001). CONCLUSIONS: Percutaneous-assisted laparoscopy has proven to be an effective and safe procedure for the excision of ovarian tissue for cryopreservation, in young oncologic patients that want to preserve their fertility. The percutaneous procedure appears superior to conventional laparoscopy in terms of aesthetic outcomes and post-operative pain reduction. CLINICAL TRIAL ID: NCT05134090, 24th Nov 2021, retrospectively registered.

The giant steps in surgical downsizing toward a personalized treatment of vulvar cancer.

The present article aims to highlight the importance of changes of personalized surgical treatment for vulvar cancer. Current international literature regarding surgical treatment of vulvar cancer was evaluated. This included several studies and systematic reviews. Radical surgery approach, such as en bloc resection, was the first therapeutic option and the standard care for many years, even if burdened with a high complication rate and frequently disfiguring. Taussing and Way introduced radical vulvectomy approach with en bloc bilateral inguinal-femoral lymphadenectomy; modified radical vulvectomy was developed, with a wide radical excision of the primary tumor. The role of inguinofemoral lymphadenectomy (mono or bilateral) changed in the years too, particularly with the advent of SLN biopsy as minimally invasive surgical approach for lymph node staging, in patients with unifocal cancer <4 cm, without suspicious groin nodes. More personalized and conservative surgical approach, consisting of wide local or wide radical excisions, is necessary to reduce complications as lymphedema or sexual disfunction. The optimal surgical management of vulvar cancer needs to consider dimensions, staging, depth of invasion, presence of carcinoma at the surgical margins of resection and grading, with the goal of making the treatment as individualized as possible.

Comparison Between Laparoscopic and Robotic Surgery in Elderly Patients With Endometrial Cancer: A Retrospective Multicentric Study.

INTRODUCTION: Elderly endometrial cancer (EEC) patients represent a challenging clinical situation because of the increasing number of clinical morbidities. In this setting of patients, minimally invasive surgery (MIS) has been shown to improve surgical and clinical outcomes. The aim of this study was to evaluate the peri-operative and oncological outcomes of EEC patients who had undergone laparoscopic (LS) or robotic surgery (RS). MATERIALS AND METHODS: This is a retrospective multi-institutional study in which endometrial cancer patients of 70 years or older who had undergone MIS for EC from April 2002 to October 2018 were considered. Owing to the non-randomized nature of the study design and the possible allocation biases arising from the retrospective comparison between LS and RS groups, we also performed a propensity score-matched analysis (PSMA). RESULTS: A total of 537 patients with EC were included in the study: 346 who underwent LS and 191 who underwent RS. No significant statistical differences were found between the two groups in terms of surgical and survival outcomes. 188 were analyzed after PSMA (94 patients in the LS group were matched with 94 patients in the RS group). The median estimated blood loss was higher in the LS group (p=0.001) and the median operative time was higher in the RS group (p=0.0003). No differences emerged between LS and RS in terms of disease free survival (DFS) (p=0.890) and overall survival (OS) (p=0.683). CONCLUSIONS: Our study showed that when compared LS and RS, RS showed lower blood losses and higher operative times. However, none of the two approaches demonstrated to be superior in terms of survival outcomes. For this reason, each patient should be evaluated individually to determine the best surgical approach.

Ultrasound evaluation shows increase in laxity after partial common extensor origin detachment but not after additional lesion of the radial band of the lateral collateral ligament.

PURPOSE: The lateral elbow musculature conveys a dynamic valgus moment to the elbow, increasing joint stability. Muscular or tendinous lesions to the anterior half of the common extensor origin (CEO) may provoke a deficiency in the elbow dynamic stabilizers, regardless of their traumatic, degenerative, or iatrogenic aetiology. Furthermore, a role for the radial band of the lateral collateral ligament (R-LCL) has been postulated in the aetiology of lateral elbow pain. This study aimed to evaluate the effects of sequential lateral releases with dynamic ultrasound, evaluating its capability to detect lesions of the CEO and of the R-LCL. METHODS: Ultrasound investigation of the lateral compartment of the elbow was performed on nine cadaveric specimens with a 10 MHz linear probe in basal conditions, after the release of the anterior half of the CEO and after complete R-LCL release. The lateral joint line widening (λ) was the primary outcome parameter, measured as the linear distance between the humeral and radial articular surfaces. RESULTS: The release of the anterior half of the CEO significantly increased λ by 200% compared to the starting position (p = 0.0008) and the previously loaded position (p = 0.0015). Conversely, further release of the R-LCL caused only a marginal, non-significant increase in λ. CONCLUSIONS: Ultrasound evaluation can detect changes related to tendon tears or muscular avulsions of the CEO and can depict lateral elbow compartmental patholaxity by assessing articular space widening while scanning under dynamic stress. However, it cannot reliably define if the R-LCL is injured. Iatrogenic damage to the CEO should be carefully avoided, since it causes a massive increase in compartmental laxity.

Case Report: Early Breast Cancer Recurrence Mimicking BIA-ALCL in a Patient With Multiple Breast Procedures.

Breast reconstruction plays a fundamental role in the therapeutic process of breast cancer treatment and breast implants represents the leading breast reconstruction strategy. Breast Implant Associated-Anaplastic Large Cell Lymphoma (BIA-ALCL), locoregional recurrence in the skin flap, and skin flap necrosis are well-known complications following mastectomy and immediate breast reconstruction (IBR). We report a case of locoregional cancer recurrence in the mastectomy flap mimicking BIA-ALCL, in a patient who underwent 6 breast procedures in four facilities across 15 years including immediate breast reconstruction with macrotextured breast implants. Despite the rate and onset of the disease, clinicians should be aware of BIA-ALCL. Due to the risk of false negative results of fine needle aspiration, clinical suspicion of BIA-ALCL should drive clinicians' choices, aside from cytological results. In the present case, surgical capsulectomy of the abnormal periprosthesic tissue revealed locoregional recurrence.

Prognostic Role of the Removed Vaginal Cuff and Its Correlation with L1CAM in Low-Risk Endometrial Adenocarcinoma.

OBJECTIVE: The aim of our study was to investigate the role of the excised vaginal cuff length as a prognostic factor in terms of DFS and recurrence rate/site, in low-risk endometrial cancer (EC) patients. Moreover, we correlated the recurrence with the expression of L1CAM. MATERIAL AND METHODS: From March 2001 to November 2016, a retrospective data collection was conducted of women undergoing surgical treatment for low-risk EC according to ESMO-ESGO-ESTRO consensus guidelines. Patients were divided into three groups according to their vaginal cuff length: V0 without vaginal cuff, V1 with a vaginal cuff shorter than 1.5 cm and V2 with a vaginal cuff longer than or equal to 1.5 cm. RESULTS: 344 patients were included in the study: 100 in the V0 group, 179 in the V1 group and 65 in the V2 group. The total recurrence rate was 6.1%: the number of patients with recurrence was 8 (8%), 10 (5.6%) and 3 (4.6%), in the V0, V1 and V2 group, respectively. No statistically significant difference was found in the recurrence rate among the three groups. Although the DFS was higher in the V2 group, the result was not significant. L1CAM was positive in 71.4% of recurrences and in 82% of the distant recurrences. CONCLUSIONS: The rate of recurrence in patients with EC at low risk of recurrence does not decrease as the length of the vaginal cuff removed increases. Furthermore, the size of the removed vaginal cuff does not affect either the site of recurrence or the likelihood of survival.

Lockdown of Breast Cancer Screening for COVID-19: Possible Scenario.

BACKGROUND/AIM: Coronavirus disease is spreading worldwide. Due to fast transmission and high fatality rate drastic emergency restrictions were issued. During the lockdown, only urgent medical services are guaranteed. All non-urgent services, as breast cancer (BC) screening, are temporarily suspended. The potential of breast cancer screening programs in increasing the survival rate and decreasing the mortality rate has been widely confirmed. Suspension could lead to worse outcomes for breast cancer patients. Our study aimed to analyse the data and provide estimates regarding the temporary BC screening suspension. PATIENTS AND METHODS: Data regarding breast cancer and respective screening programs were achieved through literature research and analysis. RESULTS: Considering three different scenarios with respect to the lockdown's impact on breast cancer screening, we estimate that approximately 10,000 patients could have a missed diagnosis during these 3 months. Considering a 6-month period, as suggested by the Imperial college model, the number of patients who will not receive a diagnosis will rise to 16,000. CONCLUSION: Breast cancer screening should be resumed as soon as possible in order to avoid further breast cancer missed diagnosis and reduce the impact of delayed diagnosis.

Development of new medical treatment for epithelial ovarian cancer recurrence.

Epithelial ovarian cancer (EOC) is the scariest gynaecological cancer. Many advances have been done with evolving knowledge, leading to the introduction of new drugs, most in maintenance setting. The antiangiogenic Bevacizumab and the three approved PARP-inhibitors-olaparib, niraparib and rucaparib-are gradually improving PFS of patients with EOC, with initial effects on OS too. But recurrence is still a heavy sentence and lethality continues to be high. Ovarian cancer is a complex disease, with different clinical presentation, histological aspect, and molecular expression, leading to disappointing results, when using a single drug. Implementation of biobanking and analysis of patients' tumour samples, before starting a treatment, could be a promising way to better understand molecular aspects of this disease, to identify markers predictive of response and to allow a better use of experimental drugs, as immunomodulators, targeted therapies, and combinations of these, to fight tumour growth and clinical progression. We reviewed the literature on the updated treatments for recurrent ovarian cancer, summarizing all the available drugs and combinations to treat patients with this diagnosis, and focusing the attention on the new approved molecules and the contemporary Clinical Trials, investigating new target therapies and new associations.
