Trends and current aspects of reconstructive surgery for gynecological cancers.

Gynecologic cancers can lead to gynecologic tract destruction with extension into both the gastrointestinal and urinary tracts. Recurrent disease can also affect the surrounding bony pelvis and pelvic musculature. As opposed to advanced ovarian cancer, where cytoreduction is the goal, in these scenarios, an oncologic approach to achieve negative margins is critical for benefit. Surgeries aimed at achieving a R0 resection in gynecologic oncology can have a significant impact on pelvic anatomy, and require reconstruction. Overall, it appears that these types of radical surgery are less frequently performed; however, when required, multidisciplinary teams at high-volume centers can potentially improve short-term morbidity. There are few data to examine the long-term, quality-of-life outcomes after reconstruction following oncologic resection in advanced and recurrent gynecologic cancers. In this review we outline considerations and approaches for reconstruction after surgery for gynecologic cancers. We also discuss areas of innovation, including minimally invasive surgery and the use of 3D surgical anatomy models for improved surgical planning.In the era of 'less is more', pelvic exenteration in gynecologic oncology is still indicated when there are no other curative-intent alternatives in persistent or recurrent gynecological malignancies confined to the pelvis or with otherwise unmanageable symptoms from fistula or radiation necrosis. Pelvic exenteration is one of the most destructive procedures performed on an elective basis, which inevitably carries a significant psychologic, sexual, physical, and emotional burden for the patient and caregivers. Such complex ultraradical surgery, which requires removal of the vagina, vulva, urinary tract, and/or gastrointestinal tract, subsequently needs creative and complex reconstructive procedures. The additional removal of sidewall or perineal structures, like pelvic floor muscles/vulva, or portions of the musculoskeletal pelvis, and the inclusion of intra-operative radiation further complicates reconstruction. This review paper will focus on the reconstruction aspects following pelvic exenteration, including options for urinary tract restoration, reconstruction of the vulva and vagina, as well as how to fill large empty spaces in the pelvis. While the predominant gastrointestinal outcome after exenteration in gynecologic oncology is an end colostomy, we also present some novel new options for gastrointestinal tract reconstruction at the end.

Clinicopathological characteristics of multiple-classifier endometrial cancers: a cohort study and systematic review.

BACKGROUND: Endometrial cancers with more than one molecular feature-POLE mutations (POLEmut), mismatch repair protein deficiency (MMRd), p53 abnormality (p53abn)-are called 'multiple classifiers'. OBJECTIVE: To describe our cohort of multiple classifiers and to report the results of a review on their incidence and the techniques used to identify them. METHODS: Multiple classifiers identified at the European Institute of Oncology, Milan, between April 2019 and Decmber 2022, were included. Clinicopathological, molecular characteristics, and oncologic outcomes were summarized and compared between single and multiple classifiers sharing common features. Studies on molecular classification of endometrial cancer were searched in the PubMed Database to collect data on the incidence of multiple classifiers and the techniques used for classification. RESULTS: Among 422 patients, 48 (11.4%) were multiple classifiers: 15 (3.6%) POLEmut-p53abn, 2 (0.5%) POLEmut-MMRd, 28 (6.6%) MMRd-p53abn, and 3 (0.7%) POLEmut-MMRd-p53abn. MMRd-p53abn and MMRd differed in histotype (non-endometrioid: 14.8% vs 2.0%, p=0.006), grade (high-grade: 55.6% vs 22.2%, p=0.001), and MMR proteins expression, whereas they differed from p53abn in histotype (non-endometrioid: 14.8% vs 50.0%, p=0.006). POLEmut-p53abn and POLEmut differed only in grade (high-grade: 66.7% vs 22.7%, p=0.008), while they differed from p53abn in age (56.1 vs 66.7 years, p=0.003), stage (advanced: 6.7% vs 53.4%, p=0.001), and histotype (non-endometrioid: 6.7% vs 50.0%, p=0.002). Two (7.1%) patients with MMRd-p53abn, 4 (4.0%) with MMRd, and 25 (34.3%) with p53abn had a recurrence. No recurrences were observed in POLEmut-p53abn and POLEmut. TP53 sequencing allowed the detection of additional 7 (18.9%) multiple classifiers with normal p53 immunostaining. The incidence of multiple classifiers ranged from 1.8% to 9.8% in 10 published studies including >100 patients. When only p53 immunohistochemistry was performed, the highest incidence was 3.9%. CONCLUSIONS: The characteristics of POLEmut-p53abn resembled those of POLEmut, whereas MMRd-p53abn appeared to be intermediate between MMRd and p53abn. The high proportion of multiple classifiers may be related to the methods used for molecular classification, which included both p53 immunohistochemistry and TP53 sequencing.

A novel algorithm to implement the molecular classification according to the new ESGO/ESTRO/ESP 2020 guidelines for endometrial cancer.

OBJECTIVE: To compare the risk class attribution with molecular classification unknown to those with molecular classification known, according to the European Society of Gynaecological Oncology/European Society for Radiotherapy and Oncology/European Society of Pathology (ESGO/ESTRO/ESP) 2020 guidelines on endometrial cancer, with a focus on risk group migration. Additionally, to evaluate the capability of a novel molecular analysis algorithm to reduce the number of required tests. METHODS: We conducted a retrospective study including all consecutive patients with endometrial cancer undergoing surgery and comprehensive molecular analyses between April 2019 and December 2021. Molecular analyses including immunohistochemistry for p53 and mismatch repair (MMR) proteins, and DNA sequencing for POLE exonuclease domain were performed to classify tumors as POLE-mutated (POLE), MMR-deficient (MMR-d), p53 abnormal (p53abn), or non-specific molecular profile (NSMP). The two risk classifications of the ESGO/ESTRO/ESP 2020 guidelines were compared to estimate the proportion of patients in which the molecular analysis was able to change the risk class attribution. We developed a novel algorithm where the molecular analyses are reserved only for patients in whom incorporation of the molecular classification could change the risk class attribution. RESULTS: A total of 278 patients were included. Molecular analyses were successful for all cases, identifying the four subgroups: 27 (9.7%) POLE, 77 (27.7%) MMR-d, 49 (17.6%) p53abn, and 125 (45.0%) NSMP. Comparison of risk class attribution between the two classification systems demonstrated discordance in the risk class assignment in 19 (6.8%, 95% CI 4.2% to 10.5%) cases. The application of our novel algorithm would have led to a reduction in the number of POLE sequencing tests by 67% (95% CI 61% to 73%) and a decrease of p53 immunohistochemistry by 27% (95% CI 22% to 33%), as compared with the application of molecular classification to all patients. CONCLUSION: Molecular categorization of endometrial cancer allows the reallocation of a considerable proportion of patients in a different risk class. Furthermore, the application of our algorithm enables a reduction in the number of required tests without affecting the risk classification.

Continuity of Cancer Care: The Surgical Experience of Two Large Cancer Hubs in London and Milan.

The SARS-CoV-2 (COVID-19) pandemic is having a large effect on the management of cancer patients. This study reports on the approach and outcomes of cancer patients receiving radical surgery with curative intent between March and September 2020 (in comparison to 2019) in the European Institute of Oncology, IRCCS (IEO) in Milan and the South East London Cancer Alliance (SELCA). Both institutions implemented a COVID-19 minimal pathway where patients were required to self-isolate prior to admission and were swabbed for COVID-19 within 72 h of surgery. Positive patients had surgery deferred until a negative swab. At IEO, radical surgeries declined by 6% as compared to the same period in 2019 (n = 1477 vs. 1560, respectively). Readmissions were required for 3% (n = 41), and <1% (n = 9) developed COVID-19, of which only one had severe disease and died. At SELCA, radical surgeries declined by 34% (n = 1553 vs. 2336). Readmissions were required for 11% (n = 36), <1% (n = 7) developed COVID-19, and none died from it. Whilst a decline in number of surgeries was observed in both centres, the implemented COVID-19 minimal pathways have shown to be safe for cancer patients requiring radical treatment, with limited complications and almost no COVID-19 infections.

Oncologic Outcomes of Robotic Radical Hysterectomy (RRH) for Patients with Early-Stage Cervical Cancer: Experience at a Referral Cancer Center.

PURPOSE: To evaluate oncologic outcomes of early stage cervical cancer patients who underwent robotic radical hysterectomy (RRH) in a referral center, a retrospective analysis was performed. METHODS: From January 2010 to December 2018, medical records of stage IA2-IIA1 cervical cancer patients, who underwent radical hysterectomy at our institute, were retrospectively reviewed. We focused our analysis on those who underwent RRH. RESULTS: A total of 198 patients were included in the final analysis. Median follow up was 52 months. At last follow-up, 188 (94.9%) women were disease-free, 9 (4.5%) had died, and 1 (0.5%) was alive with recurrent disease. At 4.5 years, PFS was 93.1% (SE ± 2.1) and OS was 95.1% (SE ± 1.8). Stratified by tumor size, PFS for tumor < 2 cm versus tumor ≥ 2 cm was statistically different (96.8% ± 2.3 and 87.9% ± 4.1 respectively, p = 0.01), as well as OS (100% and 89.8% ± 40 respectively, p = 0.01).Stratified by evidence of tumor at time of robotic surgery, PFS was statistically different in women with no residual tumor after conisation versus those with residual disease (100% ± 2.5 and 90.8% ± 2.8 respectively, p = 0.04). A recurrence occurred in 11 patients (5.6%). CONCLUSIONS: Based on our results, we could speculate that robotic approach, along with some technical precautions to avoid spillage, might be safe as primary treatment of early-stage cervical cancer, especially for tumor < 2 cm and in case of no evidence of disease at time of radical hysterectomy after previous conisation.

Robotic Surgery in the Frail Elderly: Analysis of Perioperative Outcomes.

PURPOSE: The frail are considered at higher risk for unfavorable surgical outcomes (major complications/mortality). We assessed the safety of and outcomes associated with robotic surgery in the frail elderly undergoing gynecologic procedures. METHODS: We identified patients aged ≥ 65 years who underwent a robotic procedure between May 2007 and December 2016. Frailty was defined as the presence of at least three of five frailty factors-more than five comorbidities, low physical activity, weight loss, exhaustion, and fatigue. Perioperative outcomes were recorded. We compared variables among frail and non-frail patients and performed a multivariate logistic regression to detect variables associated with major complications (≥ grade 3) or 90-day mortality. RESULTS: We identified 982 patients: 71 frail and 911 non-frail patients. Median age was 71 years. Median BMI was 29.8 kg/m2. Thirty-four patients (3.5%) had a 30-day readmission. Seventy-seven (7.8%) had a postoperative complication, of which 23 (2.3%) were major. Ninety-day mortality was 0.5%. There were significant differences with regard to age (P < 0.001), body mass index (BMI) (P < 0.001) and performance status (P < 0.001); the frail were more likely to have had surgery for oncologic reasons (P = 0.047). There were differences in hospital stay (P < 0.001), postoperative (P = 0.042) and major complications (P = 0.007), and 90-day mortality (P = 0.05). At multivariable logistic regression, age ≥ 85 was associated with major complications. BMI, performance status, and major complications were associated with 90-day mortality. CONCLUSIONS: The frail elderly have longer hospital stays and more complications after surgery than the general population, consistent with the reported literature. Careful selection of surgical candidates is required.

Is Robotic-Assisted Surgery Safe in the Elderly Population? An Analysis of Gynecologic Procedures in Patients ≥ 65 Years Old.

BACKGROUND: The elderly population is expanding worldwide but is underrepresented in clinical trials. We sought to assess the safety of robotic gynecologic surgery in an elderly cohort and to identify factors associated with unfavorable outcomes. METHODS: All patients ≥ 65 years who underwent a robotically assisted procedure at a single institution between May 2007 to December 2016 were divided into three age groups: 65-74 (Group 1); 75-84 (Group 2); ≥ 85 (Group 3). Perioperative outcomes were recorded in patients who did not require conversion to laparotomy. We compared clinical variables among groups and performed multivariate logistic regression to detect variables associated with major complications (≥ Grade 3) or 90-day mortality. RESULTS: We retrospectively identified 982 cases: 685 in Group 1; 249 in Group 2; 48 in Group 3. Median age = 71 years. Median BMI = 28.9. Malignancy was documented in 72.8% of cases; the majority were endometrial cancer (61.8%). Thirty-four patients (3.5%) were readmitted within 30 days. Seventy-seven (7.8%) had a postoperative complication, and 23 (2.3%) had a major complication. Ninety-day mortality was 0.5%. There was significant difference between groups with respect to body mass index (P = 0.026), ECOG PS (P ≤ 0.001), > 5 comorbidities (P = 0.005), hospital stay (P < 0.001), major complications (P = 0.001), and 90-day mortality (P < 0.001). On multivariable logistic regression, age ≥ 85 years was associated with major complications. Body mass index, age ≥ 85 years, and major complications were significantly associated with 90-day mortality. CONCLUSIONS: Robotic-assisted surgery appears to be safe in an elderly cohort. The incidence of overall and major complications is consistent with those reported in the literature. Patients ≥ 85 years old appear to be at higher risk of unfavorable outcomes.

Patterns of FIRST recurrence of stage IIIC1 endometrial cancer with no PARAAORTIC nodal assessment.

OBJECTIVE: To assess the rates and distribution of first recurrence in patients with FIGO stage IIIC1 endometrial cancer (EC) who did not undergo paraaortic dissection at surgical staging. METHODS: We retrospectively selected all (n = 207) stage IIIC1 patients treated at a single institution from 5/1993-1/2017. Sites of first recurrence were identified, disease-free (DFS) and overall survival (OS) calculated, multivariate logistic regression performed to identify factors associated with recurrence. RESULTS: Three-year DFS and OS were 66.5% and 85.7%, respectively. The most common histology was endometroid (64.2%). Three-year DFS was 81% (SE±3.8%) endometrioid vs. 39.5% (SE±6.6%) non-endometrioid (P < 0.001). Three-year OS was 96.9% (SE±1.8%) endometrioid vs. 65.6% (SE±6.7%) non-endometrioid (P < 0.001). Sixty-two (30.1%) patients recurred. Patterns of recurrence were: 14 (8.3%) multiple sites, 17 (8.2%) abdominal, 14 (6.8%) extra-abdominal, 17 (8.3%) isolated nodal (8 of these (3.9%) paraaortic). Patients with isolated tumor cells (ITCs) in lymph nodes only had 12/71 (17%) recurrence rate vs. 50/135 (37%) for patients with micro-/macrometastasis. On univariate analysis, grade (HR 4.67 95%CI 1.5-14.5, P = 0.008), histology (HR 4.9 95%CI 2.6-9.3, P < 0.001), myometrial invasion (HR 1.9 95%CI 1.04-3.5, P = 0.04), pelvic washing (HR 2.2 95%CI 1.1-4.5, P = 0.03), tumor volume in pelvic LNs (ITC vs. micro-/macrometastasis; HR 0.3 95%CI 0.2-0.7, P = 0.003) were associated with recurrence. On multivariate analysis, only histology was associated with recurrence (HR 7.88 95%CI 3.43-18.13, P < 0.001). CONCLUSIONS: Isolated paraaortic recurrence in stage IIIC1 EC is uncommon. Micro-/macrometastasis were associated with twice the recurrence rate compared to ITC. These data will help clinicians counsel patients with stage IIIC1 EC regarding paraaortic assessment.

Long-Term Oncologic Outcomes of Uterine-Preserving Surgery in Young Women With Stage Ib1 Cervical Cancer.

OBJECTIVE: This study aimed to evaluate oncologic outcomes of women with stage IB1 cervical cancer treated with uterine-preserving surgery (UPS) (defined as conization or trachelectomy) versus non-UPS (defined as hysterectomy of any type). METHODS: The Surveillance, Epidemiology, and End Results (SEER) database was used to identify women younger than 45 years diagnosed with stage IB1 cervical cancer from 1998 to 2012. Only those who underwent lymph node (LN) assessment were included. Outcomes of UPS versus non-UPS were analyzed. RESULTS: Among 2717 patients, 125 were treated with UPS and 2592 were treated with non-UPS. Those in the UPS group were younger (median age 33 vs 37 years, P < 0.001), less commonly had tumor size greater than 2 cm (27% vs 45%, P < 0.001), and less commonly received adjuvant radiation therapy (18% vs 29%, P = 0.006). There was no difference in distribution of tumor grade, histology, or rate of LN positivity. Median follow-up was 79 months (range, 0-179). There was no difference in 5-year disease-specific survival (DSS) between the UPS versus non-UPS groups (93% vs 94%, respectively, P = 0.755). When stratified by tumor size, DSS for UPS versus non-UPS was as follows: tumors 2 cm or less, 96.8% versus 96.3% (P = 0.683); tumors greater than 2 cm, 82.4% versus 90.4% (P = 0.112). Factors independently associated with worsened survival included adenosquamous histology (hazard ratio [HR] 2.29, 95% confidence interval [CI]1.51-3.47), G3 disease (HR 2.44, 95% CI 1.01-5.89), tumor size greater than 2 cm (HR 1.93, 95% CI 1.36-2.75) and LN positivity (HR 2.29, 95% CI 1.64-3.22). The UPS was not associated with a higher risk of death. CONCLUSIONS: The UPS does not seem to compromise oncologic outcomes in a select group of young women with stage IB1 cervical cancer, especially in the setting of tumors 2 cm or less. Further studies are needed to clarify the role of UPS in tumors greater than 2 cm.

Less versus more radical surgery in stage IB1 cervical cancer: A population-based study of long-term survival.

BACKGROUND: Standard surgical treatment for women with stage IB1 cervical cancer consists of radical hysterectomy. This study assesses survival outcomes of those treated with less radical surgery (LRS; conization, trachelectomy, simple hysterectomy) compared to more radical surgery (MRS; modified radical, radical hysterectomy). METHODS: Using the Surveillance, Epidemiology and End Results database, we identified women <45 years with FIGO stage IB1 cervical cancer diagnosed from 1/1998 to 12/2012. Only those who underwent lymph node (LN) assessment were analyzed. Disease-specific survivals (DSSs) of LRS were compared with those of MRS. RESULTS: Of 2571 patients, 807 underwent LRS and 1764 underwent MRS, all with LN assessment. For LRS vs. MRS, 28% vs. 23% were diagnosed with adenocarcinoma (p = 0.024), 31% vs. 39% had G3 disease (p < 0.001), 40% vs. 45% had tumor size >2 cm (p < 0.001), and 27% vs. 29% received adjuvant radiation therapy (p = 0.005). Median follow-up was 79 months (range, 0-179). Ten-year DSS for LRS vs. MRS was 93.5% vs. 92.3% (p = 0.511). There was no difference in 10-year DSS when stratified by tumor size ≤2 cm (LRS 95.1% vs. MRS 95.6%, p = 0.80) or > 2 cm (LRS 90.1% vs. MRS 88.2%, p = 0.48). Factors independently associated with increased risk of death included adenosquamous histology (HR 2.37), G3 disease (HR 2.86), tumors >2 cm (HR 1.82), and LN positivity (HR 2.42). Compared to MRS, LRS was not associated with a higher risk of death. CONCLUSIONS: In a select group of young women with stage IB1 cervical cancer, LRS compared to MRS does not appear to compromise DSS.

The role of macroplastique implantation in the management of occult urinary stress incontinence.

OBJECTIVE: Pelvic floor disorders, in particular pelvic organ prolapse (POP) and stress urinary incontinence (SUI), are common in women. There is a described higher risk to develop postoperative SUI also in preoperatively continent women: this happens because in 30% of women the relief of the urethral obstruction caused by prolapse, unmasks a pre-existing compromised urethral function and thus an "occult" or potential SUI. The aims of this study were to evaluate the role of Macroplastique® implant, TVT-O or surgery alone in the management of occult urinary stress incontinence during prolapse surgery in terms of success rate and adverse events. STUDY DESIGN: We enrolled 47 consecutive patients scheduled to vaginal prolapse surgery who did not report symptoms of stress incontinence. We collected surgical data, success and complication rates. Moreover we compared all the data with retrospective ones regarding surgery plus concomitant TVT-O (39 pts) and surgery alone (41 pts). RESULTS: At 12-months follow-up, we reported a success rate of 87,2% in the "macroplastique group", comparable to the "surgery plus TVT-O group", with a statistically significant difference in comparison to the "surgery alone" group. "Surgery + TVT-O" group reported a higher rate of major complications (p<0,01) in comparison to the other groups. CONCLUSIONS: Postoperative SUI prevention at the time of prolapse repair remains a challenging issue. In selected patients, Macroplastique may play an interesting role having a good success rate and a low complication rate and for these reasons it may be proposed as A concomitant procedure during POP surgery.

Prospective Comparative Study of Laparoscopic Narrow Band Imaging (NBI) Versus Standard Imaging in Gynecologic Oncology.

BACKGROUND: Narrow band imaging (NBI) is an optic filtration enhancement for endoscopy that uses two wavelengths of light (415 and 540 nm) to highlight superficial microvascular patterns. It has been successfully utilized to improve identification of lesions with abnormal vasculature, which is associated with endometriosis and endometrial cancer. Case studies suggest it may also facilitate surgical staging of gynecologic cancer, which is critical in determining appropriate adjuvant therapies. A technology that enhances the ability to identify metastatic disease during minimally invasive surgery (MIS) could make an important difference in patient outcomes. METHODS: A prospective comparative study was conducted to evaluate patients with clinical indication for diagnostic or operative laparoscopy. All received white light imaging followed by NBI during the same procedure. Suspicious lesions were examined and photographed, using both modalities, before excision. The two techniques were compared. Positive predictive value, negative predictive value, and diagnostic accuracy in identifying histologically confirmed metastatic lesions were assessed, using appropriate statistical methods. RESULTS: Of 124 patients enrolled in the study, 94 were evaluable; 30 did not undergo MIS and were therefore excluded. A significantly higher number of peritoneal abnormalities were identified with NBI versus white light imaging (P = 0.0239). However, no statistically significant difference (P = 0.18, patient level) was observed in identification of histologically confirmed metastatic disease. CONCLUSIONS: NBI imaging provides a unique contrast between peritoneal surface and microvascular patterns. However, the results of this study suggest that NBI-enhanced laparoscopy does not provide superior detection of peritoneal surface malignancy compared with standard white light high-definition laparoscopy.

Minimally invasive hysterectomy surgery rates for endometrial cancer performed at National Comprehensive Cancer Network (NCCN) Centers.

OBJECTIVES: Minimally invasive surgery (MIS) is a quality measure for endometrial cancer (EC) established by the Society of Gynecologic Oncology and the American College of Surgeons. Our study objective was to assess the proportion of EC cases performed by MIS at National Comprehensive Cancer Network (NCCN) centers and evaluate perioperative outcomes. METHODS: A retrospective cohort study of women who underwent surgical treatment for EC from 2013 to 2014 was conducted at four NCCN centers. Multivariable mixed logistic regression models analyzed factors associated with failure to perform MIS and perioperative complications. RESULTS: In total 1621 patients were evaluated; 86.5% underwent MIS (robotic-assisted 72.5%, laparoscopic 20.9%, vaginal 6.6%). On multivariable analysis, factors associated with failure to undergo MIS were uterine size >12cm (Odds Ratio [OR]: 0.17, 95% CI 0.03-0.9), stage III (OR: 0.16, 95% CI 0.05-0.49) and IV disease (OR: 0.07, 95% CI 0.02-0.22). For stage I/II disease, complications occurred in 5.1% of MIS and 21.7% of laparotomy cases (p<0.01). Laparotomy was associated with increases in any complication (OR: 6.0, 95% CI 3.3-10.8), gastrointestinal (OR: 7.2, 95% CI 2.6-19.5), wound (OR: 3.7, 95% CI 1.5-9.2), respiratory (OR 37.5, 95% CI 3.9-358.0), VTE (OR 10.5, 95% CI 1.3-82.8) and 30-day readmission (OR: 2.6, 95% CI 1.4-4.9) compared to MIS. CONCLUSIONS: At NCCN-designated centers, the MIS hysterectomy rate in EC is higher than the published national average, with low perioperative complications. Previously identified disparities of age, race, and BMI were not observed. A proposed MIS hysterectomy benchmark of >80% in EC care is feasible when performed at high volume centers.

Bilateral Otorrhagia after Robotically Assisted Gynecologic Surgery in the Setting of a Reduced Trendelenburg Position and Low-Pressure Pneumoperitoneum: A Case Report and Review of the Literature.

Perioperative otorrhagia in association with nonotolaryngologic surgery is rare. The cause is typically attributed to the physiologic derangements associated with the Trendelenburg position and pneumoperitoneum during laparoscopic surgery. The most well-accepted etiology is an increase in arterial and venous pressures causing the rupture of subcutaneous capillaries, although the exact etiology remains unclear. We present the first reported case of bilateral spontaneous otorrhagia associated with robotically assisted laparoscopic surgery involving a reduced Trendelenburg position and low-pressure pneumoperitoneum. Perioperative hypertension, female gender, advanced age, and increased bleeding risk may contribute to the development of this rare complication.

Validation of REM score to predict endometrial cancer in patients with ultrasound endometrial abnormalities: results of a new independent dataset.

The risk of endometrial malignancy (REM) score is a model formulated in a previous single-center validation study, which has been shown to predict endometrial cancer in women with ultrasound endometrial abnormalities based on multiple features (clinical, ultrasound and laboratorial). The purpose of this study was to validate the performance of REM score in an external validation setting. A population-based database with patients, who underwent elective hysteroscopy for ultrasound endometrial abnormalities between 2013 and 2016 at Department of Obstetrics and Gynecology of Campus Bio-medico of Rome, was used. Starting from January 2013 to June 2016, 330 patients were enrolled for hysteroscopy. Thirty-two patients were excluded due to Asherman syndrome or cervical stenosis. Therefore, a total of 298 patients were considered for the analysis. Based on pathologic examination, 102 patients were found to have endometrial cancer, and 196 had benign endometrial disease. Using the predefined cutoff of 0.3185, identified in the previous publication, in this independent cohort of patients we correctly classified 93/102 patients with endometrial cancer and 187/196 with benign disease, reporting an overall sensitivity and specificity of 93.9 and 95.4% (PPV = 0.91, NPV = 0.95), respectively. REM score showed a high positive predictive value for endometrial cancer prediction. However, before REM score can be applied in daily clinical practice, data from randomized controlled trials are needed.

Role of paroxetine in the management of hot flashes in gynecological cancer survivors: Results of the first randomized single-center controlled trial.

OBJECTIVES: To examine the effects of paroxetine supplementation on hot flashes and sleep in gynecological cancer survivors. METHODS: In a randomized, double-blind, placebo-controlled study, postmenopausal women with a prior history of stage 0-III gynecological cancer who had completed active cancer treatment (including hormonal therapy) were randomly assigned 1:1 to either 7.5mg oral paroxetine or placebo daily for 16weeks. Sleep and hot flashes were assessed at baseline, week 4 and week 16. RESULTS: Eighty women (91%) completed the study. We found out a statistically significant difference in weekly reductions in VMS frequency and severity for paroxetine 7.5mg than for placebo on week 4 and 16. Regarding sleep characteristics, the analysis of data through week 16 reported a statistically significant reduction in the number of nighttime awakenings attributed to VMS among participants receiving paroxetine than among participants receiving placebo on baseline and weeks. The duration of sleep per night increased significantly more among participants receiving paroxetine than among those receiving placebo at all post baseline time points. No significant differences in sleep-onset latency were noted between the two treatment arms during the course of the study. Paroxetine was well-tolerated with a high level of compliance. In our cohort of patients, no serious adverse events have been reported. CONCLUSIONS: This is the first randomized placebo-controlled study in gynecological cancer survivors that demonstrates that paroxetine significantly reduces hot flashes in weekly frequency and severity and the number of nighttime awakenings attributed to vasomotor symptoms, increasing sleep duration.
