Nationwide Introduction of Minimally Invasive Robotic Surgery for Early-Stage Endometrial Cancer and Its Association With Severe Complications

Temporal Trends in Treatment and Outcomes of Endometrial Carcinoma in the United States, 2005-2020

Endometrial cancer has continued to see a rising incidence in the US over the years. The main aim of this study was to assess current trends in patients' characteristics and outcomes of treatment for endometrial carcinoma over 16 years. A dataset from the National Cancer Database (NCDB) for patients diagnosed with endometrial carcinoma from 2005 to 2020 was used in this retrospective, case series study. The main outcomes and measures of interest included tumor characteristics, hospitalization, treatments, mortality, and overall survival. Then, 569,817 patients who were diagnosed with endometrial carcinoma were included in this study. The mean (SD) age at diagnosis was 62.7 (11.6) years, but 66,184 patients (11.6%) were younger than 50 years, indicating that more patients are getting diagnosed at younger ages. Of the patients studied, 37,079 (6.3%) were Hispanic, 52,801 (9.3%) were non-Hispanic Black, 432,058 (75.8%) were non-Hispanic White, and 48,879 (8.6%) were other non-Hispanic. Patients in the 4th period from 2017 to 2020 were diagnosed more with stage IV (7.1% vs. 5.2% vs. 5.4% vs. 5.9%; p < 0.001) disease compared with those in the other three periods. More patients with severe comorbidities (Charlson Comorbidity Index score of three) were seen in period 4 compared to the first three periods (3.9% vs. ≤1.9%). Systemic chemotherapy use (14.1% vs. 17.7% vs. 20.4% vs. 21.1%; p < 0.001) and immunotherapy (0.01% vs. 0.01% vs. 0.2% vs. 1.1%; p < 0.001) significantly increased from period 1 to 4. The use of laparotomy decreased significantly from 42.1% in period 2 to 16.7% in period 4, while robotic surgery usage significantly increased from 41.5% in period 2 to 64.3% in period 4. The 30-day and 90-day mortality decreased from 0.6% in period 1 to 0.2% in period 4 and 1.4% in period 1 to 0.6% in period 4, respectively. Over the period studied, we found increased use of immunotherapy, chemotherapy, and minimally invasive surgery for the management of endometrial cancer. Overall, the time interval from cancer diagnosis to final surgery increased by about 6 days. The improvements observed in the outcomes examined can probably be associated with the treatment trends observed.

The da Vinci robotic surgery system for the management of endometrial cancer: a single-center experience

The aim of this study was to report our single-center experience of the da Vinci robotic surgery system in the management of endometrial cancer (EC) patients during 2019-2023. We descriptively summarized the preoperative, intraoperative, and postoperative outcomes. Moreover, we conducted subgroup analyses based on obesity (BMI ≥ 30 kg/m2) and the intraoperative use of indocyanine green dye (ICG). Overall, 100 patients were analyzed. Eighty-five patients (85%) were obese. The mean operative time and estimated blood loss (EBL) were 240.84 ± 70.08 min (range: 110-720) and 104.2 ± 80.3 ml (range: 20-500), respectively. The mean number of retrieved pelvic LNs was 3.01 ± 3.06 (range: 0-15). The use of ICG was employed in 58 (58%). Only a single patient (1%) underwent conversion to laparotomy. Besides, only three (3%) patients experienced vaginal laceration intraoperatively, respectively. The mean hospital stay was 1.34 ± 0.69 days (range: 1-5). No patient experienced postoperative complications. Most tumors had endometrioid histology (82%), grade-1 tumor (49%), and stage-1A disease (67%). At 3-year follow-up, only two patients (2%) developed recurrence. Patients who received the ICG had significantly lower operative time (225.86 vs. 261.52 min, p = 0.011), estimated blood loss (90 vs. 123.81 ml, p = 0.037), and hospital stay (1.12 vs. 1.64 days, p < 0.001) compared with patients who did not receive it. However, there was no significant difference between both groups regarding the number of retrieved pelvic LNs. Obesity had no significant impact on the rates of intraoperative complications, postoperative complications, and 3-year recurrence incidence. In conclusion, robotic surgery was technically feasible and safe. The use of ICG was statistically linked to favorable outcomes, in terms of decreased operative time, EBL, and hospital stay. Obesity did not impact the perioperative surgical outcomes.

Robotic-assisted surgery for endometrial cancer: a comparison of surgical and oncologic outcomes in patients with low and high BMI at an Indian tertiary care center

The robotic-assisted surgery for endometrial cancer (EC) is becoming increasingly important, owing to the superior surgical outcomes. However, efficacy data from India is limited, particularly for older women who are obese. We undertook this study to compare the surgical outcomes of robotic-assisted surgery among Indian EC patients with a BMI of < 30 and ≥ 30 kg/m2. A retrospective chart review was conducted for the period of May 2016 to October 2020. Data on patient demographics, medical history, clinical characteristics, and perioperative outcomes were collected by a single senior surgeon, followed by statistical analysis. A total of 99 patients; 39 in the BMI group < 30 and 60 in the BMI group ≥ 30 kg/m2 were included in the study. The mean age of the BMI groups < 30 and ≥ 30 kg/m2 was 60.92 ± 10.43 and 58.90 ± 8.52 years respectively (P = 0.2944). The mean total operating time was slightly higher in the BMI group < 30 kg/m2 (P = 0.8552) but the difference was not statistically significant. Similarly, the mean blood loss (P = 0.2041), length of hospital stays (P = 0.6564), early (P = 0.7758) and delayed complications (P = 0.1878) were less in the BMI group < 30 kg/m2 but the difference was not statistically significant either. At a median follow-up of 22.3 months, the number of recurrences (5.13% vs 3.33%) and deaths (2.56% vs 1.67%) were more in BMI < 30 kg/m2 group. Our study suggests that obese older women predisposed to multiple medical co-morbidities and surgical complications would especially benefit from robotic-assisted technology regardless of their BMI.

Prince and princesses: The current status of robotic surgery in surgical oncology

Robotic surgery has experienced a dramatic increase in utilization across general surgery over the last two decades, including in surgical oncology. Although urologists and gynecologists were the first to show that this technology could be utilized in cancer surgery, the robot is now a powerful tool in the treatment of gastrointestinal, hepato-pancreatico-biliary, colorectal, endocrine, and soft tissue malignancies. While long-term outcomes are still pending, short-term outcomes have showed promise for this technologic advancement of cancer surgery.

Short-Term Outcome of Robotic versus Laparoscopic Hysterectomy for Endometrial Cancer in Women with Diabetes: Analysis of the US Nationwide Inpatient Sample

This study investigated short-term outcomes of robotic versus laparoscopic hysterectomy for endometrial cancer (EC) in women with diabetes. We extracted the data of hospitalized females aged ≥18 years who were diagnosed with EC and diabetes and underwent robotic or laparoscopic hysterectomy from the US Nationwide Inpatient Sample (NIS) 2005-2018. Associations between study variables and in-hospital outcomes, including complications, unfavorable discharge, length of stay (LOS), and hospital costs, were examined using logistic regression. A total of 5745 women (representing 28,176 women in the US) were included. Multivariable analysis revealed that robotic surgery was significantly associated with a decreased risk of unfavorable discharge (adjusted odds ratio [aOR] = 0.63, 95% confidence interval [CI]: 0.46, 0.85) than pure laparoscopic surgery. Women who underwent robotic surgery had a significantly shorter LOS (0.46 fewer days, 95% CI: -0.57, -0.35) but higher total hospital costs (6129.93 greater USD; 95% CI: 4448.74, 7811.12). Compared with pure laparoscopic surgery, robotic hysterectomy was associated with less unfavorable discharge among women aged ≥60 years (aOR = 0.60, 95% CI: 0.44, 0.80). For US women with EC and diabetes, robotic hysterectomy is associated with shorter LOS, decreased risk of unfavorable discharge, especially among older patients, and higher total costs than laparoscopic surgery.

Oncologic outcomes of robot-assisted laparoscopy versus conventional laparoscopy for the treatment of apparent early-stage endometrioid adenocarcinoma of the uterus

OBJECTIVE

To compare long-term oncologic outcomes in patients with clinically uterine-confined endometrioid endometrial cancer who underwent surgical staging with robot-assisted (RA) versus conventional laparoscopy.

METHODS

We performed a retrospective chart review of patients with newly diagnosed, uterine-confined endometrioid endometrial cancer who were treated and had primary surgery at our institution between 1/1/2009-1/1/2018. Clinicopathologic, surgical, and survival data were collected. Appropriate statistical methods were applied.

RESULTS

Of 1728 patients identified, 1389 (80.4%) underwent RA and 339 (19.6%) conventional laparoscopy. At diagnosis, median age was 60 years (range, 24-92) and median BMI was 30.2 kg/m2 (range, 15.1-71.5). In the RA group, patients had longer operative time (170 vs 152 min, P < .001), lower conversion rate to laparotomy (0.6% vs 4.7%, P < .001), and a higher proportion had a BMI > 40 kg/m2 (17.2% vs 11.5%, P = .01) and same-day discharge (19.2% vs 5.3%, P < .001). Overall, 93% (RA) and 90% (conventional) of patients underwent lymph node assessment (P = .1). Comparing the RA versus conventional groups, final surgical stage on pathology (P = .6), median follow-up (55.7 vs 52.9 months, P = .4), and rates of perioperative complications (9.9% vs 7.7%, P = .6), recurrence (9.5% vs 7.4%, P = .3), 5-year PFS (88.5% vs 91.0%, P = .3), and 5-year OS (92.5% vs 92.4%, P = .7) were not significantly different. No significant increase in risk of recurrence (HR = 1.2, 95% CI: 0.8-1.9, P = .3) or poorer OS outcomes (HR = 0.9, 95% CI: 0.6-1.4, P = .7) were observed in the RA group.

CONCLUSION

In uterine-confined endometrioid endometrial cancers, surgical staging using RA laparoscopy was not associated with adverse survival outcomes compared to conventional laparoscopy.

Evolving trends in the surgical therapy of patients with endometrial cancer in Germany: analysis of a nationwide registry with special emphasis on perioperative outcomes

PURPOSE

Endometrial cancer (EC) is the most common gynecological malignancy in women, with increasing incidence in the last decades. Surgical therapy is the mainstay of the initial management. The present study analyzed the evolving trends of surgical therapy in Germany in patients diagnosed with EC recorded in a nationwide registry.

METHODS

All patients with the diagnosis of EC undergoing open surgery, laparoscopic surgery, and robotic-assisted laparoscopic surgery between 2007 and 2018 were identified by international classification of diseases (ICD) or specific operational codes (OPS) within the database of the German federal bureau of statistics.

RESULTS

A total of 85,204 patients underwent surgical therapy for EC. Beginning with 2013, minimal-invasive surgical therapy was the leading approach for patients with EC. Open surgery was associated with a higher risk of in-hospital mortality (1.3% vs. 0.2%, p < 0.001), of prolonged mechanical ventilation (1.3% vs. 0.2%, p < 0.001), and of prolonged hospital stay (13.7 ± 10.2 days vs. 7.2 ± 5.3 days, p < 0.001) compared to laparoscopic surgery. A total of 1551 (0.04%) patients undergoing laparoscopic surgery were converted to laparotomy. Procedure costs were highest for laparotomy, followed by robotic-assisted laparoscopy and laparoscopy (8286 ± 7533€ vs. 7083 ± 3893€ vs. 6047 ± 3509€, p < 0.001).

CONCLUSION

The present study revealed that minimal-invasive surgery has increasingly become the standard surgical procedure for patients with EC in Germany. Furthermore, minimal-invasive surgery had superior in-hospital outcomes compared to laparotomy. Moreover, the use of robotic-assisted laparoscopic surgery is increasing, with a comparable in-hospital safety profile to conventional laparoscopy.

Robotic surgery in Gynecology: the present and the future

Since its introduction, laparoscopic surgery has been often preferred over open surgery in obstetrics and gynecology due to its advantages, such as less bleeding, lower incidence of adhesions, reduced postoperative pain, short hospital stay, and quick return to daily life. However, in the case of complex surgeries, laparoscopy presented some limitations. Nonetheless, since the 1980s, medical robots have been introduced to overcome the technical limitations of laparoscopy and start a new age for minimally invasive surgery. In this review, we explore the indications and advantages and disadvantages of robotic surgery in the field of gynecology, and try to assess the recent trend of robotic surgery.

Trends in surgical approach to hysterectomy and perioperative outcomes in Michigan hospitals from 2010 through 2020

The objective of this study was to determine the trends in surgical approach to hysterectomy over the last decade and compare perioperative outcomes and complications. This retrospective cohort study used clinical registry data from the Michigan Hospitals that participated in Michigan Surgical Quality Collaborative (MSQC) from January 1st, 2010 through December 30th, 2020. A multigroup time series analysis was performed to determine how surgical approach to hysterectomy [open/TAH, laparoscopic (TLH/LAVH), and robotic-assisted (RA)] has changed over the last decade. Abnormal uterine bleeding, uterine fibroids, chronic pelvic pain, pelvic organ prolapse, endometriosis, pelvic mass, and endometrial cancer were the most common indications for hysterectomy. The open approach to hysterectomy declined from 32.6 to 16.9%, a 1.9-fold decrease, with an average decline of 1.6% per year (95% CI - 2.3 to - 0.9%). Laparoscopic-assisted hysterectomies decreased from 27.2 to 23.8%, a 1.5-fold decrease, with an average decrease of 0.1% per year (95% CI - 0.7 to 0.6%). Finally, the robotic-assisted approach increased from 38.3 to 49.3%, a 1.25-fold increase, with an average of 1.1% per year (95% CI 0.5 to 1.7%). For malignant cases, open procedures decreased from 71.4 to 26.6%, a 2.7-fold decrease, while RA-hysterectomy increased from 19.0 to 58.7%, a 3.1-fold increase. After controlling for the confounding variables age, race, and gynecologic malignancy, RA hysterectomy was found to have the lowest rate of complications when compared to the vaginal, laparoscopic and open approaches. Finally, after controlling for uterine weight, black patients were twice as likely to undergo an open hysterectomy compared to white patients.

Robot-assisted versus conventional laparoscopic surgery for endometrial cancer: long-term comparison of outcomes

Objective

There is a lack of multi-institutional large-volume and long-term follow-up data on comparisons between robot-assisted surgery and conventional laparoscopic surgery. This study compared the surgical and long-term survival outcomes between patients who underwent robot-assisted or conventional laparoscopic surgery for endometrial cancer.

Methods

We retrospectively reviewed the data of patients from five large academic institutions who underwent either robot-assisted or conventional laparoscopic surgery for the treatment of endometrial cancer between 2012 and 2017, ensuring at least 5 years of potential follow-up. Intra- and postoperative outcomes, long-term disease-free survival, and overall survival were compared.

Results

The study cohort included 1,003 unselected patients: 551 and 452 patients received conventional laparoscopic and robot-assisted surgery, respectively. The median follow-up duration was 57 months. Postoperative complications were significantly less likely to occur in the robot-assisted surgery group compared to the laparoscopic surgery group (7.74% vs. 13.79%, P = 0.002), primarily limited to minor complications. There were no significant differences in survival: 5-year disease-free survival was 91.2% versus 90.0% (P = 0.628) and overall survival was 97.9% versus 96.8% (P = 0.285) in the robot-assisted and laparoscopic surgery cohorts, respectively. Cox proportional hazard regression models demonstrated that the mode of surgery was not associated with disease-free survival (hazard ratio, 0.897; confidence interval, 0.563-1.429) or overall survival (hazard ratio, 0.791; confidence interval, 0.330-1.895) after adjusting for confounding factors.

Conclusion

Robot-assisted surgery for endometrial cancer demonstrates comparable long-term survival outcomes and a reduced incidence of postoperative minor complications when compared to conventional laparoscopic surgery.

Laparoscopy with or without robotic assistance does not negatively impact long-term oncologic outcomes in patients with uterine serous carcinoma

OBJECTIVES

We sought to compare outcomes between minimally invasive surgery (MIS) and laparotomy in patients with clinical stage I uterine serous carcinoma (USC).

METHODS

Patients who underwent surgery for newly diagnosed USC between 11/1/1993 and 12/31/2017 were retrospectively identified and assigned to either the MIS cohort or the laparotomy cohort. Patients with conversion to laparotomy were analyzed with the MIS cohort. Chi-square and Mann-Whitney tests were used to compare categorical and continuous variables, respectively. Kaplan-Meier curves were used to estimate survival and compared using the log-rank test.

RESULTS

In total, 391 patients met inclusion criteria; 242 underwent MIS (35% non-robotic and 65% robotic-assisted laparoscopies) and 149 underwent laparotomy. Age, BMI, stage, and washings status did not differ between cohorts. Patients who underwent MIS were less likely to have lymphovascular space invasion (LVSI; 35.1% vs 48.3%), had fewer nodes removed (median, 9 vs 15), and lower rates of paraaortic nodal dissection (44.6% vs 65.1%). Rates of adjuvant therapy did not differ between cohorts. Median follow-up times were 63.0 months (MIS cohort) vs 71.0 months (laparotomy cohort; P = .04). Five-year PFS rates were 58.7% (MIS) vs 59.8% (laparotomy; P = .1). Five-year OS rates were 65.2% (MIS) compared to 63.5% (laparotomy; P = .2). On multivariable analysis, higher stage, deep myometrial invasion, and positive washings were associated with decreased PFS. Age ≥ 65 years, higher stage, LVSI, and positive washings were associated with shorter OS.

CONCLUSIONS

MIS does not compromise outcomes in patients with newly diagnosed USC and should be offered to these patients to minimize surgical morbidity.

Clinical Relevance of Uterine Manipulation on Oncologic Outcome in Robot-Assisted versus Open Surgery in the Management of Endometrial Cancer

In this study, we investigated the impact of uterine manipulation on endometrial cancer survival outcomes. We analyzed patients with endometrial cancer who underwent robot-assisted staging and open staging surgery between 2010 and 2020. Either uterine manipulators or vaginal tubes were utilized in robot-assisted staging. Propensity score matching was performed to correct baseline characteristics. Progression-free survival (PFS) and overall survival (OS) were analyzed using Kaplan-Meier curve analysis. In total, 574 patients, including those undergoing robot-assisted staging with a uterine manipulator (n = 213) or vaginal tube (n = 147) and staging laparotomy (n = 214), were analyzed. Propensity score matching was performed for age, histology, and stage as covariates. Before matching, Kaplan-Meier curve analysis showed that PFS and OS were significantly different among the three groups (p < 0.001 and p = 0.009, respectively). In the propensity-matched cohorts of 147 women, the previously suggested differences in PFS and OS were not observed in patients undergoing robot-assisted staging with a uterine manipulator or vaginal tube or open surgery. In conclusion, robotic surgery using a uterine manipulator or vaginal tube did not compromise survival outcomes in endometrial cancer management.

Simple radiologic assessment of visceral obesity and prediction of surgical morbidity in endometrial cancer patients undergoing laparoscopic aortic lymphadenectomy: A reliability and accuracy study

AIM

To evaluate the reliability of sagittal abdominal diameter (SAD)-a surrogate of visceral obesity-in magnetic resonance imaging, and its accuracy to predict the surgical morbidity of aortic lymphadenectomy.

METHODS

We conducted a multicenter reliability (phase 1) and accuracy (phase 2) cohort study in three Spanish referral hospitals. We retrospectively analyzed data from the STELLA-2 randomized controlled trial that included high-risk endometrial cancer patients undergoing minimally invasive surgical staging. Patients were classified into subgroups: conventional versus robotic-assisted laparoscopy, and transperitoneal versus extraperitoneal technique. In the first phase, we measured the agreement of three SAD measurements (at the umbilicus, renal vein, and inferior mesenteric artery) and selected the most reliable one. In phase 2, we evaluated the diagnostic accuracy of SAD to predict surgical morbidity. Surgical morbidity was the main outcome measure, it was defined by a core outcome set including variables related to blood loss, operative time, surgical complications, and para-aortic lymphadenectomy difficulty.

RESULTS

In phase 1, all measurements showed good inter-rater and intra-rater agreement. Umbilical SAD (u-SAD) was the most reliable one. In phase 2, we included 136 patients. u-SAD had a good diagnostic accuracy to predict surgical morbidity in patients undergoing transperitoneal laparoscopic lymphadenectomy (0.73 in ROC curve). It performed better than body mass index and other anthropometric measurements. We calculated a cut-off point of 246 mm (sensitivity: 0.56, specificity: 0.80).

CONCLUSIONS

u-SAD is a simple, reliable, and potentially useful measurement to predict surgical morbidity in endometrial cancer patients undergoing minimally invasive surgical staging, especially when facing transperitoneal aortic lymphadenectomy.

Survival Analysis in Endometrial Carcinomas by Type of Surgical Approach: A Matched-Pair Study

Simple Summary

We carried out a retrospective cohort study of 1382 women diagnosed with endometrial cancer (EC). A total of 684 (49.5%) were operated on by minimally invasive surgery (MIS), 233 (34%) by robotic-assisted laparoscopy (RAL), 451 (66%) by conventional laparoscopy (LPS), and 698 (50.5%) by open surgery (OP). Disease-free (DFS), overall (OS), and specific survival related to EC (SS) outcomes were significantly higher for MIS compared to OP. When matched by age, BMI, co-morbidities, ASA score, histological type, grade, myometrial invasion, and FIGO stage, the DFS, OS, and SS amounts were similar between the MIS and OP groups. The surgical approach for women with EC does not impact disease-free or overall survival amounts when matched by homogeneous groups, but laparoscopy seems to offer a higher specific overall survival rate compared to the open surgery approach.

Abstract

(1) Background: This study aimed to analyze the impact of surgical approach on survival rates in women diagnosed with endometrial cancer. (2) Methods: A retrospective multicenter cohort of 1382 women diagnosed with EC was performed. A total of 684 (49.5%) women underwent minimally invasive surgery, 233 (34%) underwent robotic-assisted laparoscopy (RAL), 451 (66%) underwent conventional laparoscopy (LPS), and 698 (50.5%) underwent open surgery (OP). Sociodemographic features, tumor characteristics, and survival rates were analyzed in the whole sample and in a matched-pair model. (3) Results: Women operated on by OP were significantly older, presented more comorbidities, and had more aggressive tumors. Disease-free (DFS), overall (OS), and specific survival related to EC (SS) amounts were significantly higher for MIS compared to OP (p < 0.001). When matched by age, body mass index, comorbidities, ASA score, histological type, grade, myometrial invasion, and FIGO stage, 798 patients were selected. DFS, OS, and SS amounts were similar between the MIS and OP groups. (4) Conclusions: The surgical approach for women with EC does not impact DFS or OS amounts when matched by homogeneous groups.

Determinants of Surgical Approach and Survival Among Women with Endometrial Carcinoma

STUDY OBJECTIVE

To investigate determinants of surgical approach among women with endometrial carcinoma (EC) and associations between surgical approach and overall survival (OS).

DESIGN

Retrospective cohort.

SETTING

The National Cancer Database, 2010 to 2015.

PATIENTS

A total of 140 470 patients with histologically confirmed EC who underwent hysterectomy.

INTERVENTIONS

Patients were grouped according to surgical approach.

MEASUREMENTS AND MAIN RESULTS

A total of 140 470 patients with EC were included. Robotic-assisted laparoscopy (RAL) was the most common surgical approach (48.8%), followed by laparotomy (33.6%) and traditional laparoscopy (17.6%). Use of RAL increased over the study period, and the percentages of cases managed by laparotomy decreased. Older women, those with insurance, residing in ZIP codes with lower proportions of individuals who did not graduate from high school, and those treated at noncommunity cancer programs were less likely to undergo laparotomy than RAL, and non-white women, those diagnosed with high-grade histology, and those with advanced-stage EC were more likely to undergo laparotomy than RAL. Compared with RAL, all other surgical approaches were associated with worse OS (laparotomy: hazard ratio 1.21; 95% confidence interval, 1.18-1.25; traditional laparoscopy: hazard ratio 1.06; 95% confidence interval, 1.02-1.09). Significant effect modification of the surgical approach and OS relationship according to age, race, histology, stage, and adjuvant treatment was observed.

CONCLUSION

RAL increased in frequency over the study period and was associated with improved OS, supporting the continued use of RAL for EC management.

European Society of Gynaecological Oncology quality indicators for the surgical treatment of endometrial carcinoma

BACKGROUND

Quality of surgical care as a crucial component of a comprehensive multi-disciplinary management improves outcomes in patients with endometrial carcinoma, notably helping to avoid suboptimal surgical treatment. Quality indicators (QIs) enable healthcare professionals to measure their clinical management with regard to ideal standards of care.

OBJECTIVE

In order to complete its set of QIs for the surgical management of gynecological cancers, the European Society of Gynaecological Oncology (ESGO) initiated the development of QIs for the surgical treatment of endometrial carcinoma.

METHODS

QIs were based on scientific evidence and/or expert consensus. The development process included a systematic literature search for the identification of potential QIs and documentation of the scientific evidence, two consensus meetings of a group of international experts, an internal validation process, and external review by a large international panel of clinicians and patient representatives. QIs were defined using a structured format comprising metrics specifications, and targets. A scoring system was then developed to ensure applicability and feasibility of a future ESGO accreditation process based on these QIs for endometrial carcinoma surgery and support any institutional or governmental quality assurance programs.

RESULTS

Twenty-nine structural, process and outcome indicators were defined. QIs 1-5 are general indicators related to center case load, training, experience of the surgeon, structured multi-disciplinarity of the team and active participation in clinical research. QIs 6 and 7 are related to the adequate pre-operative investigations. QIs 8-22 are related to peri-operative standards of care. QI 23 is related to molecular markers for endometrial carcinoma diagnosis and as determinants for treatment decisions. QI 24 addresses the compliance of management of patients after primary surgical treatment with the standards of care. QIs 25-29 highlight the need for a systematic assessment of surgical morbidity and oncologic outcome as well as standardized and comprehensive documentation of surgical and pathological elements. Each QI was associated with a score. An assessment form including a scoring system was built as basis for ESGO accreditation of centers for endometrial cancer surgery.

Post robotic investment: Cost consequences and impact on length of stay for obese women with endometrial cancer

INTRODUCTION

The aim of the study was to investigate whether robotic-assisted surgery is associated with lower incremental resource use among obese patients relative to non-obese patients after a Danish nationwide adoption of robotic-assisted surgery in women with early-stage endometrial cancer. This is a population-based cohort study based on registers and clinical data.

MATERIAL AND METHODS

All women who underwent surgery (robotic, laparoscopic and laparotomy) from 2008 to 2015 were included and divided according to body mass index (<30 and ≥30). Robotic-assisted surgery was gradually introduced in Denmark (2008-2013). We compared resource use post-surgery in obese vs non-obese women who underwent surgery before and after a nationwide adoption of robotic-assisted surgery. The key exposure variable was exposure to robotic-assisted surgery. Clinical and sociodemographic data were linked with national register data to determine costs and bed days 12 months before and after surgery applying difference-in-difference analyses.

RESULTS

In total, 3934 women were included. The adoption of robotic-assisted surgery did not demonstrate statistically significant implications for total costs among obese women (€3,417; 95% confidence interval [CI] -€854 to €7,688, p = 0.117). Further, for obese women, a statistically significant reduction in bed days related to the index hospitalization was demonstrated (-1.9 bed days; 95% CI -3.6 to -0.2, p = 0.025). However, for non-obese women, the adoption of robotic-assisted surgery was associated with statistically significant total costs increments of €9,333 (95% CI €3,729-€1,4936, p = 0.001) and no reduction in bed days related to the index hospitalization was observed (+0.9 bed days; 95% CI -0.6 to 2.3, p = 0.242).

CONCLUSIONS

The national investment in robotic-assisted surgery for endometrial cancer seems to have more modest cost implications post-surgery for obese women. This may be partly driven by a significant reduction in bed days related to the index hospitalization among obese women, as well as reductions in subsequent hospitalizations.

Trends in Hysterectomy Incidence Rates During 2000-2015 in Denmark: Shifting from Abdominal to Minimally Invasive Surgical Procedures

Background

Hysterectomy (removal of the uterus) is a common surgical procedure in gynecology. Although minimally invasive surgical procedures have been introduced, hysterectomy is still associated with risk of short- and long-term complications. Given that hysterectomized women are no longer at risk of either hysterectomy or being diagnosed with endometrial or cervical cancer, it is important to describe trends in hysterectomy rates.

Objective

To describe trends in hysterectomy incidence rates overall and stratified by age, indication, and procedure.

Methods

Nationwide population-based cohort study using Danish national registries, 2000–2015, was conducted. We calculated the overall hysterectomy-corrected and age-standardized incidence rates of hysterectomy among women ≥20 years old. Incidence rates were stratified by age group, indication, and surgical procedure. We performed trend analyses using Joinpoint regression, thereby estimating the average annual percentage change (AAPC).

Results

A total of 98,484 women had a hysterectomy during the study period, corresponding to an overall age-standardized, hysterectomy-corrected hysterectomy incidence rate (SIR) of 351.1 per 100,000 person-years (95% CI 348.9;353.3). SIR of hysterectomy declined over time (AAPC −1.4; 95% CI −1.9;-1.0), which was driven by a decline in rates of benign hysterectomy (AAPC −2.1; 95% CI −2.7;-1.6). Irrespective of indication, rates of abdominal hysterectomy declined substantially during the study period and were surpassed by rates of minimally invasive procedures (ie, laparoscopy and robot-assisted laparoscopy) in 2013.

Conclusion

Hysterectomy-corrected incidence rates of benign hysterectomy declined over time. Irrespective of indication, we observed a shift in surgical procedure over time, from abdominal hysterectomy to minimally invasive surgical procedures.

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.

ESGO/ESTRO/ESP guidelines for the management of patients with endometrial carcinoma

A European consensus conference on endometrial carcinoma was held in 2014 to produce multidisciplinary evidence-based guidelines on selected questions. Given the large body of literature on the management of endometrial carcinoma published since 2014, the European Society of Gynaecological Oncology (ESGO), the European SocieTy for Radiotherapy & Oncology (ESTRO) and the European Society of Pathology (ESP) jointly decided to update these evidence-based guidelines and to cover new topics in order to improve the quality of care for women with endometrial carcinoma across Europe and worldwide. ESGO/ESTRO/ESP nominated an international multidisciplinary development group consisting of practicing clinicians and researchers who have demonstrated leadership and expertise in the care and research of endometrial carcinoma (27 experts across Europe). To ensure that the guidelines are evidence-based, the literature published since 2014, identified from a systematic search was reviewed and critically appraised. In the absence of any clear scientific evidence, judgment was based on the professional experience and consensus of the development group. The guidelines are thus based on the best available evidence and expert agreement. Prior to publication, the guidelines were reviewed by 191 independent international practitioners in cancer care delivery and patient representatives. The guidelines comprehensively cover endometrial carcinoma staging, definition of prognostic risk groups integrating molecular markers, pre- and intra-operative work-up, fertility preservation, management for early, advanced, metastatic, and recurrent disease and palliative treatment. Principles of radiotherapy and pathological evaluation are also defined.

Care as Usual: An Acceptable Strategy to Apply During the COVID-19 Pandemic in a French Tertiary Gynecologic Oncology Department

We describe and analyze a “care as usual” strategy of a French Comprehensive Cancer Center during the COVID-19 pandemic to manage surgical patients with gynecological cancer. We conducted a retrospective analysis evaluating the surgical activity in our gynecologic oncology department between January 21 and May 12, 2020. We compared the surgical activity and surgical and oncologic outcomes during the pre-lockdown period and the pandemic period. The main objective was to evaluate the impact of the COVID-19 pandemic on surgical activity. The secondary objectives were to analyze the surgical and the oncologic outcomes. We compared the surgical activity during the 8 weeks after the national lockdown (85 procedures) to the surgical activity in the 8 weeks preceding the lockdown (127 procedures). We observed a 33% decrease in activity between the two periods. The clinical and epidemiologic characteristics were similar between the two periods. There were no differences between the surgical approaches (p = 0.592), the surgical complexity (p = 0.323), the length of stay (p = 0.85), and even for the complex procedure (p = 0.96) and the perioperative (p = 0.791) and postoperative complication rates (p = 0.102). We observed a significant decrease in the time of return to intended oncological treatment (RIOT) during the lockdown period with an average of 31.9 days compared to 46.9 days in the pre-lockdown period (p = 0.003). During the COVID-19 pandemic, “care as usual” represents an acceptable strategy without impairing the oncologic outcome in a Comprehensive Cancer Center with a patient-centered clinical pathway for gynecologic oncologic surgical patients.

Risk Factors and Outcomes of Conversion to Open Surgery in Benign Gynecologic Laparoscopies: A Case-Control Study

STUDY OBJECTIVE

To describe cases of conversion from gynecologic laparoscopy to open surgery and to assess risk factors for conversion and conversion outcomes.

DESIGN

A retrospective case-control study.

SETTING

Tertiary referral hospital in Melbourne, Australia.

PATIENTS

Eighty-five cases of conversion from laparoscopy to laparotomy and 170 controls matched by age, surgical date, and gynecologic unit from 2006 to 2017.

INTERVENTIONS

Demographic, clinical, and surgical data were collected and compared between the study groups. Logistic regression was performed to identify preoperative and intraoperative risk factors for conversion.

MEASUREMENTS AND MAIN RESULTS

Rate of conversion during the study period was 0.7%. The most common indication for conversion was unexpected surgical complexity (67% of cases), which included severe adhesive disease, specimen size, severe pathology, and inadequate views. Factors that were significantly associated with risk of conversion in multivariate analysis were previous pelvic inflammatory disease (adjusted odds ratio [aOR] 5.16; 95% confidence interval [CI], 1.35-19.71; p = .02), previous open surgery (aOR 3.62; 95% CI, 1.52-8.58; p <.01), history of endometriosis (aOR 2.96; 95% CI, 1.17-7.50; p = .02), and elevated body mass index (aOR 1.07; 95% CI, 1.01-1.13; p = .02). As compared with current surgery for endometriosis, odds of conversion were higher in surgeries for emergency indications (aOR 5.40; 95% CI, 1.53-18.98; p <.01), uterine pathologies (aOR 3.34; 95% CI, 1.10-10.12; p = .03), and adnexal pathologies (aOR 2.76; 95% CI, 1.19-6.40; p = .02). With the inclusion of intraoperative factors, surgical adhesions were also found to be associated with conversion (aOR 3.19; 95% CI, 1.30-7.85; p = .01). Most skilled laparoscopic surgeon level as defined by the Australasian Gynaecological Endoscopy and Surgery Society was not associated with conversion risk. Conversion to laparotomy was associated with a higher rate of intraoperative and postoperative complications and prolonged length of stay.

CONCLUSION

Conversion to laparotomy is a rare but very important clinical outcome measure of laparoscopic surgery. Understanding the factors contributing to conversion and perioperative outcomes may help clinicians to identify and counsel patients before surgery and to reduce surgical morbidity.

Comparative Survival Outcome of Robot-Assisted Staging Surgery Using Three Robotic Arms versus Open Surgery for Endometrial Cancer

PURPOSE

There is lack of data on direct comparison of survival outcomes between open surgery and robot-assisted staging surgery (RSS) using three robotic arms for endometrial cancer. The purpose of this study was to compare the overall survival (OS) and disease-free survival (DFS) between open surgery and RSS using three robotic arms for endometrial cancer.

MATERIALS AND METHODS

Consecutive women with endometrial cancer who underwent surgery between May 2006 and May 2018 were identified. Robotic procedures were performed using the da Vinci robotic system, and the robotic approach consisted of three robotic arms including a camera arm. Propensity score matching, as well as univariate and multivariate Cox regression of OS and DFS were performed according to clinicopathologic data and surgical method.

RESULTS

The study cohort included 423 unselected patients with endometrial cancer, of whom 218 underwent open surgery and 205 underwent RSS using three robotic arms. Propensity score-matched cohorts of 146 women in each surgical group showed no significant differences in survival: 5-year OS of 91% vs. 92% and DFS of 86% vs. 89% in the open and robotic cohorts, respectively (hazard ratio, 1.02; 95% confidence interval, 0.82-1.67). In the univariate analysis with OS as the endpoint, surgical method, age, stage, type II histology, grade, and lymph node metastasis were independently associated with survival. Surgical stage, grade, and type II histology were found to be significant independent predictors for OS in the multivariate analysis.

CONCLUSION

RSS using three robotic arms and laparotomy for endometrial carcinoma had comparable survival outcomes.

The effect of surgical approach on the outcomes and prognosis of high-risk histologic endometrioid carcinomas

Background

High-risk histologic endometrioid carcinomas include poorly differentiated endometrial carcinoma (PDEC), uterine clear cell carcinoma (UCCC), uterine carcinosarcoma (UCS), and uterine papillary serous carcinomas (UPCS). The purpose of this study was to investigate and compare the effect of open surgery and minimally invasive surgery on the prognosis of patients with high-risk endometrial cancer tissue types.

Methods

A retrospective analysis was conducted to investigate 57 UCS or UPCS, 53 UCCC, and 110 PDEC patients receiving initial treatment at the Department of Gynecology in Shaanxi Provincial Tumor hospital and the Affiliated Hospital of Medical College of Xi'an Jiaotong University between February 2010 and January 2015. Prognostic factors were determined using univariate/multivariate analysis, and survival rates were assessed using the Kaplan-Meier method. The Cox regression model was adopted to assess the independent prognostic factors.

Results

Two hundred and twenty patients who met the criteria were included in this study. At the end of follow-up period, 94 patients were still alive. Univariate analysis found that the survival time of the patients was related to staging, adjuvant therapy, and surgical approach. Multivariate analysis revealed that surgical approach, staging, pathology, and adjuvant therapy were independent prognostic factors.

Conclusions

Minimally invasive surgery has a shorter survival time compared to open surgery in women with PDEC, UCCC, UCS, and UPCS. Multivariate analysis confirmed that staging, pathological type, surgical approach, and postoperative adjuvant therapy are independent risk factors for prognosis and affect the survival of women with PDEC, UCCC, UCS, and UPCS.

Robotic vs. open surgery in obese women with low-grade endometrial cancer: comparison of costs and quality of life measures

Background

This retrospective study compared perioperative measures, costs, quality of life and survival after open vs. robotic surgery, among obese women diagnosed with low-grade endometrial cancer.

Methods

Obese women (body mass index (BMI) ≥ 30) who underwent open or robotic surgery for endometrial cancer, in one of two tertiary medical centers in the center of Israel, 2013–2016, postoperative grade 1–2, were included. Costs per patient, including 30-days post-surgery were calculated. Quality of life was evaluated by Physical and Mental Components of the SF-36 and a recovery from surgery questionnaire. Overall survival outcomes were obtained from patients’ files. Surgical outcomes, including operating and anesthesia times, length of hospital stay, and intraoperative and postoperative complications according to the Clavien-Dindo classification scale were reviewed.

Results

In all, 138 women with BMI ≥30 underwent open (n = 61) or robotic surgery (n = 77) during the study period. The groups had similar BMI, comorbidities, demographics and tumor characteristics. Robotic surgery was associated with shorter hospital stays (mean 1.7 vs. 4.8 days; P < .0001) and fewer postoperative complications (Clavien-Dindo > 2, 5.2% vs. 19.7%; P = .0008), but longer operating theater time (3.8 vs. 2.8 h; P < .001). Costs are equivalent when at least 350 robotic surgeries are performed annually, not including the initial system costs. Quality of life measures were better after robotic surgery. SF-36 showed better measures for robotic surgery (Physical 56 vs. 39 and Mental 73 vs. 56; P < .01). After robotic surgery, patients tended to recover quicker when compared to open surgery, as they returned to normal activities earlier, with less need for family and governmental assistance (mean recovery time, 23 vs. 70 days; P < 0.006 and mean change in preoperative total functioning score, − 1.5 vs. -3.9: P < 0.05, respectively). Overall, 5-year survival was 89.8% for the open surgery group vs. 94% for the robotic surgery group (log rank, P = 0.330).

Conclusions

Obese women with low-grade endometrial cancer had better quality of life after robotic vs. open surgery. They also had shorter hospital stays and fewer postoperative complications. Centers with high volumes of robotic surgery can achieve similar costs when comparing both methods. These results were achieved without jeopardizing survival. Our results further emphasize the need for the Israeli healthcare system to include specific reimbursement for robotic procedures in the population we studied.

Nationwide Comparison of Surgical and Oncologic Outcomes in Endometrial Cancer Patients Undergoing Robotic, Laparoscopic, and Open Surgery: A Population-Based Cohort Study

Purpose

Population-based comparisons between minimally invasive surgery (MIS) (robotic surgery [RS] and laparoscopic surgery [LS]) and open surgery (OS) for managing endometrial cancer are lacking. This study aimed to compare surgical and oncologic outcomes between endometrial cancer patients who underwent surgical staging via MIS or OS.

Materials and Methods

A population-based retrospective cohort study was performed using claims data from the Korean National Health Insurance database from January 2012 to December 2016. All patients who underwent hysterectomy under diagnosis of endometrial cancer were identified. Patients were classified into RS, LS, and OS groups. Operative and oncologic outcomes were compared among the three groups after adjustments for age group, risk group (adjuvant therapy status), modified Charlson comorbidity index, income level, insurance type, and index year using propensity scores obtained via the inverse probability of treatment weighted method.

Results

After adjustment, 5,065 patients (RS, n=315; LS, n=3,248; OS, n=1,503) were analyzed. Patient demographics were comparable. Hospital stay, postoperative complications, and cost were more favorable in the RS and LS groups than in the OS group (all p < 0.001). Five-year overall survival was significantly longer in the RS and LS groups than in the OS group (94.8%, 91.9%, and 86.9%, respectively; p < 0.001). Moreover, the survival benefit of RS was shown in the subgroup analysis of low-risk endometrial cancer patients.

Conclusion

Our study provides further evidence for the RS being a safe surgical alternative to the LS and OS, especially in low-risk endometrial cancer patients, offering surgical and oncologic outcomes equivalent to other surgical approaches.

Surgical trends, outcomes and disparities in minimal invasive surgery for patients with endometrial cancer in England: a retrospective cohort study

OBJECTIVE

To examine surgical outcomes and trends in the implementation of minimally invasive surgery (MIS) use for endometrial cancer (EC).

DESIGN

Retrospective cohort study.

SETTING

English National Health Service hospitals 2011-2017/2018.

POPULATION

35 304 patients having a hysterectomy for EC identified from Hospital Episode Statistics.

METHODS

Univariate and multivariate analyses compared MIS to open hysterectomy (OH) by assessing the association between demographic, clinical and hospital characteristics by using logistic regression. A propensity score was created, to control for confounding factors including demographics, clinical and hospital characteristics, from a logistic regression which enabled the inverse probability weighting of treatment to be applied in order to compare outcomes of treatment.

MAIN OUTCOME MEASURES

The association between route of surgery on perioperative morbidity and mortality.

RESULTS

The MIS rate rose from 40.3% in 2011 to 68.7% in 2017/2018, however, there was significant geographical variation (p<0.001). The overall 90-day mortality was significantly higher with OH versus MIS (OR 0.34, 95% CI 0.18 to 0.62, p=0.0002). MIS rates were significantly lower in patients from the lowest socioeconomic group (LSEG) compared with patients from the highest group (HSEG) (55.4% vs 59.9%, p<0.01), and in the black population as compared with white and Asian populations (40.4% vs 58.6% and 56.0%, p<0.0001). When patients from LSEG and black patients were treated in hospitals with high MIS rates, the MIS rate increased close to that of the HSEG and white patients (81.0% and 74.1% vs 83.2% and 82.6%).

CONCLUSIONS

Further investigation is needed to understand the barriers to MIS and improve access so that as many patients as possible can benefit from the reduced morbidity/mortality associated with MIS.

Comparison of perioperative outcomes and technical features using da Vinci Si and Xi robotic platforms for early stages of endometrial cancer

We directly compared perioperative outcomes and technical features between previous da Vinci Si and the newer Xi robotic platform during total hysterectomy plus salpingo-oophorectomy with or without lymphadenectomy for early-stage endometrial cancer. We retrospectively analyzed147 patients with histological confirmation of endometrial carcinoma stage IA: grade 1-2, 3 and stage IB: grade 1-2 who underwent surgery with da Vinci Si or Xi system between January 2016 and December 2018. Perioperative data, technical features and postoperative complications were considered. 91 patients underwent surgery with the Si system and 56 with the Xi system. Docking time using the Xi system was significantly shorter (p < 0.002), while overall operating time was similar. There were no significant differences in the number of harvested lymph nodes, conversion rate, mean hospital stay, complications, and technical aspects between the two groups. Our study detected similar perioperative outcomes and the trend toward shorter docking and operating time for Xi over Si robot.

Robotic surgery for gynecologic cancers: indications, techniques and controversies

Minimally invasive surgery for gynecologic cancers is associated with fewer postoperative complications including less blood loss and quicker recovery time compared to traditional laparotomy. The robotic platform has allowed patients access to minimally invasive surgery due to its increased utilization by gynecologic oncologists. Many surgeons have embraced the robotic platform due to its technological advances over traditional laparoscopy including high-definition 3D optics, wristed instrumentation, camera stability and improved ergonomics. While robotic surgery continues as a mainstay in the management of gynecologic cancers, it remains controversial in regards to its cost effectiveness and more recently, its long-term impact on clinical and oncologic outcomes. A strong component of the justification of this surgical platform is based on extrapolated data from traditional laparoscopy despite limited prospective randomized trials for robotic-assisted surgery. In this review, we highlight the use of robotic surgery in the management of gynecologic cancers in special populations: fertility sparing patients, the morbidly obese, the elderly, and patients with a favorable response to neoadjuvant chemotherapy.

Evaluation of quality of life, body image and surgical outcomes of robotic total laparoscopic hysterectomy and sentinel lymph node mapping in low-risk endometrial cancer patients - A Robotic Gyne Club study

INTRODUCTION

The aims of the study were to evaluate quality of life, cosmetic results and surgical outcomes of robotic single-site and robotic multiport total laparoscopic hysterectomy with sentinel lymph node mapping in women treated for low-risk endometrial cancer.

MATERIAL AND METHODS

The study is a prospective, multicenter, case-control study conducted at Ospedale Santa Chiara in Trento and Novara and Pavia University Hospitals. Seventy-six consecutive patients with a biopsy-confirmed diagnosis of low-risk endometrial cancer or atypical endometrial hyperplasia who between January 2017 and January 2019 had undergone robotic total laparoscopic hysterectomy and sentinel lymph node mapping were included. Data on surgical outcomes, quality of life and cosmetic results were prospectively collected and analyzed based on the surgical approach with robotic single-site vs robotic multiport assistance. Patients' clinical characteristics, intra-operative parameters, sentinel lymph node mapping results and postoperative findings were prospectively recorded. Clinical follow up was performed 4 weeks and 6 and 12 months after surgery. Fifty-one patients underwent a robotic multiport procedure and 25 patients a robotic single-site surgery.

RESULTS

There was one significant difference between the two groups in terms of patient characteristics: mean body mass index (BMI) in the multiport group was 29 kg/m² vs 24.8 kg/m² in the single-site group (P value <.001). After univariate and multivariate analysis on intraoperative and postoperative findings, a shorter surgical time was observed in the single-site cohort than in the multiport group (148.7 vs 158.2 minutes, P value .0182). BMI also had a significant effect on surgical time (P = .022). No differences were seen in terms of sentinel lymph node detection: the bilateral detection rate was 96.1% for multiport (66.7% bilateral, 29.4% monolateral) and 96% for single-site (76% bilateral, 20% monolateral) procedures. No differences between the two approaches were identified with regard to postoperative complications, pain, cosmetic results or quality of life comparisons.

CONCLUSIONS

For the treatment of low-risk endometrial cancer and atypical endometrial hyperplasia with total hysterectomy and sentinel lymph node mapping, the robotic single-port approach is comparable to the multiport procedure in terms of intraoperative and postoperative findings, and has an advantage in terms of shorter surgical times. Further studies are required to identify possible differences in quality of life and cosmetic results.

Laparotomy or minimal invasive surgery in uterus transplantation: a comparison

Uterus transplantation (UTx) is the first available treatment for absolute uterine factor infertility, a condition due to absence of the uterus or presence of a non-functional uterus. The proof-of-concept of UTx as an infertility treatment for this group of patients occurred in 2014 in Sweden by the first birth after human UTx. That and subsequent cases of the Swedish trial were live-donor UTx procedures with laparotomy of both donor and recipient. Although results of the initial Swedish clinical UTx trial were very favorable in terms of take-home-baby rate, the drawback was the long duration (>10 h) of donor surgeries and associated long recovery periods. There exist three later publications, with uterus procurements from live donors by laparotomy with a range of surgical durations of 5.3 hours to 13 hours. Our collaborative Swedish-French team has initiated efforts to introduce minimal invasive surgery in one trial in Sweden and one in France. The principle of these UTx trials is to use modern concepts of robotic-assisted laparoscopy primarily in the live donor. There also exists a small number of published UTx procedures with donor surgery by partial conventional laparoscopy and one published case with total robotic-assisted laparoscopy procedure. This review discusses open versus minimal invasive surgery in relation to the accumulated knowledge in the field. Moreover, we propose some future directions for the development of this surgery in UTx.

Minimally Invasive Surgery Rate as a Quality Metric for Endometrial Cancer

STUDY OBJECTIVE

To determine the frequency with which Commission on Cancer-accredited hospitals met a metric of ≥80% minimally invasively performed hysterectomies for endometrial cancer and to compare the clinical outcomes of hospitals meeting this metric with those that did not.

DESIGN

Retrospective cohort study.

SETTING

Hospitals caring for ≥20 endometrial cancer patients per year recorded in the National Cancer Database in 2015 were included.

PATIENTS

Women who had undergone hysterectomy for endometrial cancer and had an epithelial histology, a Charlson comorbidity score of 0, and stage I to III disease.

INTERVENTION

Patient characteristics, patterns of care, and outcomes were compared between hospitals performing ≥80% minimally invasive hysterectomies and hospitals not meeting this metric.

MEASUREMENTS AND MAIN RESULTS

The hospitals (n = 510) treated 20 670 women with endometrial cancer. In 283 (55%) hospitals ≥80% of hysterectomies were minimally invasively performed (high-minimally invasive surgery [MIS] hospitals, overall MIS rate 89%). In the 227 hospitals that did not meet this metric, 61% of hysterectomies for endometrial cancer were performed using a minimally invasive approach. In high-MIS hospitals, patients were more likely to be white (87% vs 82%, p<.001), privately insured (53% vs 49%, p <.001), and have stage I disease (84% vs 82%, p = .002) and an endometrioid histology (79% vs 76%, p <.001). Surgery was more often performed robotically (80% vs 71%), and conversion to laparotomy was less likely (1.5% vs 3.2%, adjusted odds ratio [aOR], 0.47; 95% confidence interval [CI], 0.39-0.57) (both p <.001). Patients treated at high-MIS hospitals were more likely to have undergone lymph node assessment at the time of surgery (76% vs 69%; aOR, 1.43; 95% CI, 1.35-1.53) and been discharged on the same or next day (74% vs 57%; aOR, 2.27; 95% CI, 2.13-2.42) and were less likely to have an unplanned 30-day readmission (1.8% vs 2.9%; aOR, 0.64; 95% CI, 0.53-0.77).

CONCLUSION

An MIS rate of ≥80% for endometrial cancer is feasible on a national scale and is associated with other hospital-level measurements of high-quality care.

Long term resource consequences of a nationwide introduction of robotic surgery for women with early stage endometrial cancer

OBJECTIVE

The majority of cost-studies related to robotic surgery has a short follow-up and primarily report the costs from the index surgery. The aim of this study was to evaluate the long-term resource consequences of introducing robotic surgery for early stage endometrial cancer in Denmark.

METHODS

The study included all women with early stage endometrial cancer who underwent robotic, laparoscopic and open access surgery from January 2008 to June 2015. Data was linked from national databases to determine resource consumption and costs from hospital treatments, outpatient contacts, primary health care sector visits, labor market affiliation and prescription of medication. Each patient was observed in a period of 12 months before- and after surgery. The key exposure variable was women who were exposed to robotic surgery compared to those who were not.

RESULTS

A total of 4133 women underwent surgery for early stage endometrial cancer. The study found additional costs of $7309 (95% confidence interval [CI] 2100-11,620, P = 0.001) per patient in the group exposed to robotic surgery including long-term costs post-surgery compared to the non-exposed group (non-robotic group). When controlling for time trends, the introduction of robotic surgery did not reduce the number of bed days (mean diff -0.42, 95% CI -3.03-2.19, P = 0.752).

CONCLUSIONS

The introduction of robotic surgery for early stage endometrial cancer did not generate any long-term cost savings. The additional costs of robotic surgery were primarily driven by the index surgery. Any reduction in bed days could be explained by time trends.

New insights into early recovery after robotic surgery for endometrial cancer

OBJECTIVE

To assess early recovery of physical health after robotic minimally invasive surgery (RMIS) for early-stage endometrial cancer using the European Organisation of Research and Treatment of Cancer Computer Adaptive Test Core questionnaire (EORTC CAT Core). The EORTC CAT Core provides individualised measurements while maintaining comparability. A hypothesis of individual complete recovery to baseline within three post-surgical weeks was evaluated.

METHODS

Ninety-four women who underwent RMIS for early-stage endometrial cancer were included consecutively. The EORTC CAT Core was distributed before surgery and prospectively every week during the first post-operative month. Repeated measures models were fitted for each of the four domains (physical functioning, role function, fatigue, and pain) and tested for impact of age, ASA score, minor/major surgery, and the individual baseline scores (poorest, intermediate, best).

RESULTS

Women with the lowest physical functioning, lowest role function, highest fatigue level, and highest pain level at baseline all recovered within three weeks. Women with the highest physical functioning, highest role function, lowest level of fatigue, and lowest level of pain at baseline did not reach their individual baselines within the first post-operative month but had the most favourable domain-scores three weeks post-operatively.

CONCLUSION

The individual woman's physical health baseline score is predictive for her postoperative recovery following RMIS for early-stage endometrial cancer. Women with the best physical health had the best postoperative functions and lowest level of symptoms; however their recovery to baseline was prolonged. Computer adaptive testing may be a valuable tool for individualised pre-operative information and supportive care during surveillance.
