Perioperative outcomes of women with and without class III obesity undergoing hysterectomy for endometrioid endometrial cancer: A population-based study

Surgical Treatment for Endometrial Cancer, Hysterectomy Performed via Minimally Invasive Routes Compared with Open Surgery: A Systematic Review and Network Meta-Analysis

Background: Total hysterectomy with bilateral salpingo-oophorectomy via minimally invasive surgery (MIS) has emerged as the standard of care for early-stage endometrial cancer (EC). Prior systematic reviews and meta-analyses have focused on outcomes reported solely from randomised controlled trials (RCTs), overlooking valuable data from non-randomised studies. This inaugural systematic review and network meta-analysis comprehensively compares clinical and oncological outcomes between MIS and open surgery for early-stage EC, incorporating evidence from randomised and non-randomised studies. Methods: This study was prospectively registered on PROSPERO (CRD42020186959). All original research of any experimental design reporting clinical and oncological outcomes of surgical treatment for endometrial cancer was included. Study selection was restricted to English-language peer-reviewed journal articles published 1 January 1995-31 December 2021. A Bayesian network meta-analysis was conducted. Results: A total of 99 studies were included in the network meta-analysis, comprising 181,716 women and 14 outcomes. Compared with open surgery, laparoscopic and robotic-assisted surgery demonstrated reduced blood loss and length of hospital stay but increased operating time. Compared with laparoscopic surgery, robotic-assisted surgery was associated with a significant reduction in ileus (OR = 0.40, 95% CrI: 0.17-0.87) and total intra-operative complications (OR = 0.38, 95% CrI: 0.17-0.75) as well as a higher disease-free survival (OR = 2.45, 95% CrI: 1.04-6.34). Conclusions: For treating early endometrial cancer, minimal-access surgery via robotic-assisted or laparoscopic techniques appears safer and more efficacious than open surgery. Robotic-assisted surgery is associated with fewer complications and favourable oncological outcomes.

vNOTES (vaginal natural orifice transluminal surgery) gynecologic procedures in morbidly and super-morbidly obese women: five year experience

PURPOSE

To analyze our experience with vNOTES gynecologic procedures in women with morbid and super morbid obesity to determine feasibility and compare outcomes with standard minimally invasive techniques.

METHODS

Gynecologic procedures performed by three surgeons on women with a body mass index (BMI) ≥ 40 kg/m2 from 2017 to 2023. A subset of women with a BMI ≥ 50 kg/m2 was also analyzed.

RESULTS

103 women with a BMI ≥ 40 kg/m2 were identified (Class IV), 19 of whom had a BMI ≥ 50 kg/m2 (Class V). For the entire population the mean BMI was 45.7 kg/m2 (40-62). 29 women were nulliparous and 23 had at least one prior cesarean delivery. 51 had no prior abdominal surgery. The procedures performed were hysterectomy and removal of adnexae in 77 patients, hysterectomy alone in six, adnexal surgery alone in nine, and hysterectomy with adnexectomy and lymph nodes in five. Two surgeries were converted to laparoscopy and five to laparotomy. Average surgical time was 87 min (30-232). Average blood loss was 82 mL (10-400). Mean uterine weight was 206 g (29-2890). 53 procedures were performed as outpatient, 44 had overnight observation, four had a length of stay of 2 days, one each for 4 days and 5 days. The laparoscopies occurred in one patient with an obliterated cul-de-sac and in one patient for lymph node removal. The laparotomies occurred for adnexal adhesions in one, bleeding in two, a cystotomy in one requiring urology consultation, and an obliterated cul-de-sac One patient developed a postoperative vaginal cuff hematoma not requiring intervention.

CONCLUSION

vNOTES gynecologic procedures are feasible in this high-risk population and may result in shorter recovery times and fewer complications than standard laparoscopy or transvaginal surgery. What does this study add to the clinical work: VNOTES approach is feasible in morbidly obese women and may have distinct advantages over conventional laparoscopic, vaginal or open techniques.

A meta-analysis of the risk factors of surgical site infection after hysterectomy for endometrial cancer

Surgical Site Infection (SSI) is one of the common postoperative complications after hysterectomy for endometrial cancer (EC). Previous studies have investigated the risk factors for SSI in patients with EC. However, big differences in research results exist, and the correlation coefficients of different research results are quite different. A meta-analysis was conducted to examine the risk factors related to SSI in patients with EC. We searched English databases to collect case-control studies or cohort studies published before July 20, 2023, including PubMed, Web of Science, Embase and ScienceDirect. The risk of bias in the included studies was assessed via Newcastle-Ottawa Scale. The analysis was performed using RevMan 5.4.1 tool. A total of 6 articles (n = 3647) were selected in this meta-analysis. The following risk factors were presented to be significantly correlated with SSI in EC: laparotomy (OR = 2.66, 95% CI [1.57, 4.54]), postoperative blood sugar ≥10 mmol/L (OR = 4.38, 95% CI [2.83, 6.78]), Federation International of Gynaecology and Obstetrics (FIGO) stage-III or IV (OR = 2.27, 95% CI [1.49, 3.46]). The occurrence of SSI is influenced by a variety of factors. Thus, we should pay close attention to high-risk subjects and take crucial targeted interventions to lower the SSI risk after hysterectomy. Owing to the limited quality and quantity of the included studies, more rigorous studies with adequate sample sizes are needed to verify the conclusion.

Bariatric surgery reduces odds of perioperative complications after inpatient hysterectomy: Analysis from a national database, 2016 to 2018

BACKGROUND

Increased body mass index is a known risk factor for increased adverse events post-hysterectomy. The effects of previous bariatric surgery on outcomes after inpatient hysterectomy are not well elucidated.

METHODS

The 2016 to 2018 National Inpatient Sample was queried for patients who underwent hysterectomy using International Classification of Disease 10 Procedure Codes before a matched analysis was performed to neutralize the potential confounding effects of comorbidities, body mass index, and age. Patients were divided into the following 2 groups: a case group (those with a history of bariatric surgery) and a control group (those without a history of bariatric surgery). Patients in the respective groups were matched 1:2 by age, Elixhauser comorbidity score, and body mass index at the time of surgery to analyze the risk of complications and mean length of stay.

RESULTS

When 1:2 case-control matching was performed, women with a history of bariatric surgery (N = 595) had significantly fewer complications and decreased mean length of stay than the non-bariatric group (N = 1,190), even after controlling for body mass index at the time of hysterectomy.

CONCLUSIONS

When matched for age, body mass index, and comorbidity score, patients with previous bariatric surgery had fewer complications and shorter lengths of stay than patients without a history of bariatric surgery. Women with a body mass index ≥40 kg/m2 requiring non-urgent hysterectomy may benefit from undergoing bariatric surgery first.

Associations between body mass index and all-cause mortality: A systematic review and meta-analysis

Fasting insulin and c-reactive protein confound the association between mortality and body mass index. An increase in fat mass may mediate the associations between hyperinsulinemia, hyperinflammation, and mortality. The objective of this study was to describe the "average" associations between body mass index and the risk of mortality and to explore how adjusting for fasting insulin and markers of inflammation might modify the association of BMI with mortality. MEDLINE and EMBASE were searched for studies published in 2020. Studies with adult participants where BMI and vital status was assessed were included. BMI was required to be categorized into groups or parametrized as non-first order polynomials or splines. All-cause mortality was regressed against mean BMI squared within seven broad clinical populations. Study was modeled as a random intercept. β coefficients and 95% confidence intervals are reported along with estimates of mortality risk by BMIs of 20, 30, and 40 kg/m2 . Bubble plots with regression lines are drawn, showing the associations between mortality and BMI. Splines results were summarized. There were 154 included studies with 6,685,979 participants. Only five (3.2%) studies adjusted for a marker of inflammation, and no studies adjusted for fasting insulin. There were significant associations between higher BMIs and lower mortality risk in cardiovascular (unadjusted β -0.829 [95% CI -1.313, -0.345] and adjusted β -0.746 [95% CI -1.471, -0.021]), Covid-19 (unadjusted β -0.333 [95% CI -0.650, -0.015]), critically ill (adjusted β -0.550 [95% CI -1.091, -0.010]), and surgical (unadjusted β -0.415 [95% CI -0.824, -0.006]) populations. The associations for general, cancer, and non-communicable disease populations were not significant. Heterogeneity was very large (I2  ≥ 97%). The role of obesity as a driver of excess mortality should be critically re-examined, in parallel with increased efforts to determine the harms of hyperinsulinemia and chronic inflammation.

An institutional study: Does Body Mass Index influence surgical approach, surgical morbidities, and outcomes in endometrial cancer patients?

Background

Endometrial Cancer (EC), the most common genital tract malignancy in women, is recognised to be associated with a high Body Mass Index (BMI).

Objective

The aim of the study was to evaluate the impact of obesity on intra and post-operative morbidity for patients treated for EC.

Materials and Methods

This was a retrospective observational study including patients with EC that were surgically treated at Hospital de la Santa Creu i Sant Pau during nine consecutive years. The patients were divided in groups according to BMI: <30 Kg/m2, ≥30-<40 Kg/m2 and ≥40 Kg/m2. Demographic and pathological characteristics, surgical outcomes, perioperative complications and long-term outcomes were recorded.

Results

The study included 290 patients; 164 patients with BMI <30 Kg/m2(56.5%), 107 patients with ≥30-<40 Kg/m2 36.9%) and 19 patients with ≥40 Kg/m2(6.65%). Patients with BMI ≥40Kg/m2 were younger, presented a higher percentage of endometrioid histology (84.2%, p<0.01), well-differentiated tumours (73.7%, p<0.01) and were more frequently in the initial stages at diagnosis (94.7%) compared to the other groups. A significant percentage of the patients were operated on laparoscopically (88.7%, 88.8%, 94.7% respectively). No significant differences were found in the evaluation of the surgical outcomes. The results relative to complications showed an overall tendency toward increase in the ≥40 Kg/m2 BMI group but no statistical differences were identified among the groups in terms of complications or long-term outcomes.

Conclusions

There was a rising trend towards increased complications with increasing BMI in the study population, however, this was found not to be statistically significant. Therefore, the optimisation of co-morbidities and the adaptation of surgical treatment is important for the management of obese patients with endometrial cancer.

What is new?

The study allows the comparison between groups with different BMI in patients with endometrial cancer. Different surgical outcomes, intra operative, early, and late complications are clearly identified, and survival outcomes are also investigated in our study.

Impact of Patient Body Mass Index on Post-Operative Recovery from Robotic-Assisted Hysterectomy

A longitudinal, descriptive, prospective, and prolective study of individuals with endometrial or cervical cancer/pre-cancer diagnoses and high BMI (over 35 kg/m2) undergoing RH was conducted. Of the 53 participants recruited, 3 (6%) were converted to open surgery. The 50 RH participants had median BMI 42 kg/m2 (range 35 to 60): the range 35-39.9 kg/m2 had 17 cases; the range 40-44.9 kg/m2 had 15 cases; 45-49.9 kg/m2 8 cases; and those ≥50 kg/m2 comprised 10 cases. The mean RH operating time was 128.1 min (SD 25.3) and the median length of hospital stay was 2 days (range 1-14 days). Increased BMI was associated with small, but statistically significant, increases in operating time and anaesthetic time, 65 additional seconds and 37 seconds, respectively, for each unit increase in BMI. The median self-reported time for individuals who underwent RH to return to their pre-operative activity levels was 4 weeks (range 2 to >12 weeks). There was a significant improvement in pain and physical independence scores over time (p = 0.001 and p < 0.001, respectively) and no significant difference in scores for overall QOL, pain, or physical independence scores was found between the BMI groups. Patient-reported recovery and quality of life following RH is high in individuals with high BMI (over 35 kg/m2) and does not appear to be impacted by the severity of obesity.

Enhanced Recovery after Uterine Corpus Cancer Surgery: A 10 Year Retrospective Cohort Study of Robotic Surgery in an NHS Cancer Centre

Simple Summary

Surgical and survival outcomes for uterine corpus cancer following the introduction of robotic surgery to Royal Surrey NHS Foundation Trust; a large volume United Kingdom teaching hospital and cancer centre. Introduction of the Da Vinci^TM robot was associated with enhanced recovery after surgery with low 30-day mortality (0.1%), low return to theatre (0.5%), a low use of blood transfusion and intensive care (1.8% & 7.2% respectively), low conversion to open surgery (0.5%) and a reduction in median length of stay, with comparable survival to published data, and a three to four fold increase in cases treated. This increased productivity was associated with a highly predicable patient pathway of care, for high-risk patients, with reduced demands on health services.

Abstract

Royal Surrey NHS Foundation Trust introduced robotic surgery for uterine corpus cancer in 2010 to support increased access to minimally invasive surgery, a central element of an enhanced recovery after surgery (ERAS) pathway. More than 1750 gynaecological oncology robotic procedures have now been performed at Royal Surrey NHS Foundation Trust. A retrospective cohort study was performed of patients undergoing surgery for uterine corpus cancer between the 1 January 2010 and the 31 December 2019 to evaluate its success. Data was extracted from the dedicated gynaecological oncology database and a detailed notes review performed. During this time; 952 patients received primary surgery for uterine corpus cancer; robotic: n = 734; open: n = 164; other minimally invasive surgery: n = 54. The introduction of the Da Vinci^TM robot to Royal Surrey NHS Foundation Trust was associated with an increase in the minimally invasive surgery rate. Prior to the introduction of robotic surgery in 2008 the minimally invasive surgery (MIS) rate was 33% for women with uterine corpus cancer undergoing full surgical staging. In 2019, 10 years after the start of the robotic surgery program 91.3% of women with uterine corpus cancer received robotic surgery. Overall the MIS rate increased from 33% in 2008 to 92.9% in 2019. Robotic surgery is associated with a low 30-day mortality (0.1%), low return to theatre (0.5%), a low use of blood transfusion and intensive care (1.8% & 7.2% respectively), low conversion to open surgery (0.5%) and a reduction in median length of stay from 6 days (in 2008) to 1 day, regardless of age/BMI. Robotic survival is consistent with published data. Introduction of the robotic program for the treatment of uterine cancer increased productivity and was associated with a highly predicable patient pathway of care, for high-risk patients, with reduced demands on health services. Future health care commissioning should further expand access to robotic surgery nationally for women with uterine corpus cancer.

Levonorgestrel-releasing intrauterine system versus systemic progestins in management of endometrial hyperplasia: A systemic review and meta-analysis

INTRODUCTION

Endometrial hyperplasia is associated with varying risk of endometrial cancer. The aim of this review is to assess effectiveness of levonorgestrel-releasing intrauterine system (LNG-IUS), compared to systemic progestins, in management of endometrial hyperplasia MATERIALS AND METHODS: A search on studies comparing LNG-IUS to systemic progestins was conducted on Scopus, Web of science, Cochrane, PubMed and Embase databases, from the date of inception to September 20th, 2020. Studies were excluded if they were non-comparative, animal studies, review articles, case reports, case series, and conference papers. Primary outcomes include resolution/regression rate, failure rate, and hysterectomy rate. Analysis was pooled using random effect model and was expressed as pooled odds ratios (OR) and 95% confidence interval (CI). Quality assessment was performed using Cochrane Risk of Bias Tool and the Newcastle-Ottawa Scale (NOS) assessment tool. MOGGE Meta-analysis Matrix was used to illustrate multiple subgroup analyses.

RESULTS

Out of 341 studies retrieved from literature search, 12 were eligible. LNG-IUS yielded significantly higher resolution/regression rate (91.3% vs 68.6%, OR 3.42, 95% CI 1.86-6.30). Failure and hysterectomy rates were significantly lower in LNG-IUS group compared to systemic progestins' group (19.2% vs. 32.3%, OR 0.34, 95% CI 0.20-0.57 and 9.3% vs. 24.1%, OR 0.41, 95% CI 0.29-0.57, respectively). Subgroup analysis of studies including complex hyperplasia only did not show significant difference in resolution/regression rate was not statistically significant.

CONCLUSION

LNG-IUS is associated with high success rate in management of women with endometrial hyperplasia. However, specific effectiveness of LNG-IUS on more advanced histologic subtypes is less studied.

Current and Emerging Prognostic Biomarkers in Endometrial Cancer

Endometrial cancer is the most common gynaecological malignancy in high income countries and its incidence is rising. Whilst most women with endometrial cancer are diagnosed with highly curable disease and have good outcomes, a significant minority present with adverse clinico-pathological characteristics that herald a poor prognosis. Prognostic biomarkers that reliably select those at greatest risk of disease recurrence and death can guide management strategies to ensure that patients receive appropriate evidence-based and personalised care. The Cancer Genome Atlas substantially advanced our understanding of the molecular diversity of endometrial cancer and informed the development of simplified, pragmatic and cost-effective classifiers with prognostic implications and potential for clinical translation. Several blood-based biomarkers including proteins, metabolites, circulating tumour cells, circulating tumour DNA and inflammatory parameters have also shown promise for endometrial cancer risk assessment. This review provides an update on the established and emerging prognostic biomarkers in endometrial cancer.

Impact of socio-economic deprivation on endometrial cancer survival in the North West of England: a prospective database analysis

OBJECTIVE

To assess the impact of socio-economic deprivation on endometrial cancer survival.

DESIGN

Single-centre prospective database study.

SETTING

North West England.

POPULATION

Women with endometrial cancer treated between 2010 and 2015.

METHODS

Areal-level socio-economic status, using the English indices of multiple deprivation from residential postcodes, was analysed in relation to survival using Kaplan-Meier estimation and multivariable Cox regression.

MAIN OUTCOME MEASURES

Overall survival, cancer-specific survival and patterns and rates of recurrence.

RESULTS

A total of 539 women, with a median age of 66 years (interquartile range, IQR 56-73 years) and a body mass index (BMI) of 32 kg/m2 (IQR 26-39 kg/m2 ), were included in the analysis. Women in the most deprived social group were younger (median 64 years, IQR 55-72 years) and more obese (median 34 kg/m2 , IQR 28-42 kg/m2 ) than women in the least deprived group (median age 68 years, IQR 60-74 years; BMI 29 kg/m2 , IQR 25-36 kg/m2 ; P = 0.002 and <0.001, respectively). There were no differences in endometrial cancer type, stage or grade between social groups. There was no difference in recurrence rates, however, women in the middle and most deprived social groups were more likely to present with distant/metastatic recurrence (80.6 and 79.2%, respectively) than women in the least deprived group (43.5%, P < 0.001). Women in the middle and most deprived groups had a two-fold (adjusted hazard ratio, HR = 2.00, 95% CI 1.07-3.73, P = 0.030) and 53% (adjusted HR = 1.53, 95% CI 0.77-3.04, P = 0.221) increase in cancer-specific mortality compared with women in the least deprived group. There were no differences in overall survival.

CONCLUSIONS

We found that socio-economically deprived women with endometrial cancer were more likely to develop fatal recurrence. Larger studies are needed to confirm these findings and to identify modifiable contributing factors.

TWEETABLE ABSTRACT

Socio-economic deprivation is linked to an increased risk of death from endometrial cancer in the North West of England.

Laparoscopic and Robotic Surgery for Endometrial and Cervical Cancer

Minimally invasive surgery (MIS) has many benefits, in the form of reduced postoperative morbidity, improved recovery and reduced inpatient stay. It is imperative, however, when new techniques are adopted, in the context of treating oncology patients, that the oncological efficacy and safety are established rigorously rather than assumed based on first principles. Here we have attempted to provide a comprehensive review of all the contentious and topical themes surrounding the use of MIS in the treatment of endometrial and cervix cancer following a thorough review of the literature. On the topic of endometrial cancer, we cover the role of laparoscopy in both early and advanced disease, together with the role and unique benefits of robotic surgery. The surgical challenge of patients with a raised body mass index and the frail and elderly are discussed and finally the role of sentinel lymph node assessment. For cervical cancer, the role of MIS for staging and primary treatment is covered, together with the interesting and highly specialist topics of fertility-sparing treatment, ovarian transposition and the live birth rate associated with this. We end with a discussion on the evidence surrounding the role of adjuvant hysterectomy following radical chemoradiation and pelvic exenteration for recurrent cervical cancer. MIS is the standard of care for endometrial cancer. The future of MIS for cervix cancer, however, remains uncertain. Current recommendations, based on the available evidence, are that the open approach should be considered the gold standard for the surgical management of early cervical cancer and that MIS should only be adopted in the context of research. Careful counselling of patients on the current evidence, discussing in detail the risks and benefits to enable them to make an informed choice, remains paramount.
