Abstract
BACKGROUND We present a systematic review and network meta-analysis (NMA) that is the precursor underpinning the Bayesian analyses that adjust for publication bias, presented in the same edition in AJT. The review assesses optimal cytoreduction for women undergoing primary advanced epithelial ovarian cancer (EOC) surgery. AREAS OF UNCERTAINTY To assess the impact of residual disease (RD) after primary debulking surgery in women with advanced EOC. This review explores the impact of leaving varying levels of primary debulking surgery. DATA SOURCES We conducted a systematic review and random-effects NMA for overall survival (OS) to incorporate direct and indirect estimates of RD thresholds, including concurrent comparative, retrospective studies of ≥100 adult women (18+ years) with surgically staged advanced EOC (FIGO stage III/IV) who had confirmed histological diagnoses of ovarian cancer. Pairwise meta-analyses of all directly compared RD thresholds was previously performed before conducting this NMA, and the statistical heterogeneity of studies within each comparison was evaluated using recommended methods. THERAPEUTIC ADVANCES Twenty-five studies (n = 20,927) were included. Analyses demonstrated the prognostic importance of complete cytoreduction to no macroscopic residual disease (NMRD), with a hazard ratio for OS of 2.0 (95% confidence interval, 1.8-2.2) for <1 cm RD threshold versus NMRD. NMRD was associated with prolonged survival across all RD thresholds. Leaving NMRD was predicted to provide longest survival (probability of being best = 99%). The results were robust to sensitivity analysis including only those studies that adjusted for extent of disease at primary surgery (hazard ratio 2.3, 95% confidence interval, 1.9-2.6). The overall certainty of evidence was moderate and statistical adjustment of effect estimates in included studies minimized bias. CONCLUSIONS The results confirm a strong association between complete cytoreduction to NMRD and improved OS. The NMA approach forms part of the methods guidance underpinning policy making in many jurisdictions. Our analyses present an extension to the previous work in this area.

Gynae-Oncology Surgeons’ Preparedness to Undertake Colorectal Procedures during Cytoreductive Surgery for Ovarian Cancer: A Cross Sectional Survey. J Clin Med 2022; 11:jcm11216233. [DOI: 10.3390/jcm11216233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 10/05/2022] [Accepted: 10/21/2022] [Indexed: 11/06/2022] Open
Abstract
Cytoreductive surgery for advanced ovarian cancer commonly involves bowel resection. Although UK gynaecological oncologists are trained in bowel surgery, the degree to which they perform bowel surgery independently varies nationally. A recent joint policy statement from the British Gynaecological Cancer Society (BGCS) emphasises the need for formalised colorectal support. An anonymous, online survey was emailed to BGCS members to assess the status of multidisciplinary working between UK gynaecological oncology and colorectal/general surgical teams. A total of 46 members responded (8.2% response rate). There was a large variety in the involvement of colorectal/general surgical teams in preoperative planning. A total of 13% of respondents had no formalised agreement for intraoperative support, 72.1% of respondents independently performed rectal peritoneal stripping and 60.5% independently performed small bowel resection. This was reduced to 27.9% for right hemicolectomy with primary anastomosis and 16.3% for left hemicolectomy with primary anastomosis. Respondents often involved colorectal support for post-operative complications. The majority of UK gynaecological oncologists involve colorectal/general surgical teams in bowel procedures, more commonly for large bowel procedures compared to small bowel and for left colon compared to right colon procedures. A total of 16.3% of respondents independently performed all surveyed bowel procedures. Future research should examine training and experience within these groups to address this disparity.

Activity profile in a Gynecology Department: 7-year observational cohort. Eur J Obstet Gynecol Reprod Biol 2021; 267:142-149. [PMID: 34773876 DOI: 10.1016/j.ejogrb.2021.09.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Revised: 08/31/2021] [Accepted: 09/21/2021] [Indexed: 11/28/2022]
Abstract
OBJECTIVE Bowel resection is frequently used when performing oncological surgery to obtain complete cytoreduction or to remove endometriosis in case of intestinal invasion. Acquiring the surgical skills to perform this kind of procedure is crucial to offer to our patients an optimal management. The aim of this study is to describe a 7-years surgical experience in bowel resections of a gynecologic surgeon and to determine his learning curves. STUDY DESIGN This is a monocentric retrospective cohort study reporting digestive resection performed between January 2013 and April 2020 in the Gynecology Department of Strasbourg University Hospital. Ninety-one consecutive patients were assigned in two groups: gynecological cancer (n = 44) and deep infiltrating endometriosis (DIE) (n = 47). The main outcome measure was the postoperative complications rate at 30 days, based on the modified Clavien-Dindo severity system. Learning curves were evaluated using cumulative sum (CUSUM) analysis of operative time and risk-adjusted cumulative sum (RA-CUSUM) analysis of severe perioperative complications. Identification of predictive factors for operation duration and severe perioperative complication occurrence was conducted using multivariate analysis. RESULTS Minor complications were found in 25% of cases. Major complication rate (Clavien-Dindo ≥ IIIa) was 14% in total and only involved patients operated for cancer. The CUSUM curve for operative time peaked at the 35th case and showed a downward slope after the 45th case. Significant predictive factors of operating time were cytoreductive tumoral surgery, size of the bowel resection and laparoscopic surgery, while learning phase 3 significantly decreased it. The RA-CUSUM curve for severe perioperative complications (Clavien-Dindo ≥ IIIa) showed a progressive decrease in the complication rate as the number of interventions increases without showing clear inflection points. Only cardiopulmonary pathologies were found as significant predictive factor of severe complications. CONCLUSION Proficiency in performing highly complex surgery was achieved after approximately 45 cases, cancer and DIE all together. Acceptable rates of severe perioperative complications were observed even during the initial learning period and are comparable with those found in the literature concerning bowel resection performed by gynecologic oncologists but also by general and digestive surgeons.

Abstract
Objective This study was performed to examine the safety of bowel resection and upper abdominal surgery in patients with advanced ovarian cancer performed by gynecologic oncologists after training in a monodisciplinary surgical team. Methods We implemented a monodisciplinary surgical team consisting of specialized gynecologic oncologist for advanced ovarian cancer. In the initial learning period in 65 patients with International Federation of Gynecology and Obstetrics (FIGO) III/IV, a gynecologic oncologist who had a certification as a general surgeon trained 2 other gynecologic oncologists in bowel resection and upper abdominal surgery for 4 years. After the initial learning period, the trained gynecologic oncologists performed surgeries without the certificated general surgeon in 195 patients with FIGO III/IV. The surgical outcomes and perioperative complications during the 2 periods were evaluated. Results The rates of achieving no gross disease after cytoreductive surgery were 80.0% in the initial learning period and 83.6% in the post-learning period (p=0.560). The incidence of anastomotic leakage after rectosigmoid resection, symptomatic pleural effusion or pneumothorax after right diaphragm resection, and pancreatic fistula after splenectomy with distal pancreatectomy in the 2 periods were 2 of 34 (6.0%), 1 of 33 (3.0%), and 3 of 15 (20.0%) patients in the initial learning period, and 12 of 147 (8.2%), 1 of 118 (0.8%), and 11 of 84 (13.1%) patients in the post-learning period, respectively. There were no significant differences between the 2 groups (p=0.270, p=0.440, p=0.520, respectively). Conclusion Bowel resection and upper abdominal surgery can be performed safely by gynecologic oncologists.

Abstract
OBJECTIVE The objective of this study was to assess the scope of intestinal surgery training across gynecologic oncology fellowships in the United States and identify factors associated with perceived preparedness to perform intestinal surgery independently. MATERIALS/METHODS An institutional review board-approved survey was distributed to Society of Gynecologic Oncology fellows and candidate members within the first 3 years of practice. Questions addressed demographics, operative experience, preparedness and plans for performing intestinal surgery, and attitudes toward gynecologic oncologists (GOs) performing intestinal surgery. Responses were analyzed using descriptive statistics as well as univariate and multivariate analyses. RESULTS Of 374 Society of Gynecologic Oncology members invited, 108 (29%) responded, including 38 fellows (35%) and 53 recent graduates (49%). Fifteen (14%) reported more than 3 years of practice and were excluded. Most participants (96%) received intestinal surgery training from GOs, and 64% reported that all faculty routinely performed intestinal surgery. Most participants (81%) believed GOs should perform intestinal procedures, whereas only 58% felt prepared and 59% planned to perform intestinal procedures independently. Fellows who performed more than 10 intestinal diversion procedures, participated directed in intestine-related intraoperative consultations, or reported that all faculty performed intestinal surgery were more likely to feel prepared to perform intestinal surgery independently. Sex, training region, intended practice environment, and fellowship curriculum were not associated with preparedness to perform intestinal surgery. CONCLUSIONS Almost half of gynecologic oncology fellows and recent graduates in the United States do not feel prepared to perform intestinal procedures independently after fellowship. Increased volume and direct involvement of fellows in intestinal surgery may improve preparedness for performing intestinal surgery after fellowship.

Abstract
OBJECTIVE To assess site of disease on preoperative computed tomography (CT) to predict surgical debulking in patients with ovarian cancer. DESIGN Two-phase retrospective cohort study. SETTING West London Gynaecological Cancer Centre, UK. POPULATION Women with stage 3 or 4, ovarian, fallopian or primary peritoneal cancer undergoing cytoreductive surgery. METHODS Preoperative CT images were reviewed by experienced radiologists to assess the presence or absence of disease at predetermined sites. Multivariable stepwise logistic regression models determined sites of disease which were significantly associated with surgical outcomes in the test (n = 111) and validation (n = 70) sets. MAIN OUTCOME MEASURES Sensitivity and specificity of CT in predicting surgical outcome. RESULTS Stepwise logistic regression identified that the presence of lung metastasis, pleural effusion, deposits on the large-bowel mesentery and small-bowel mesentery, and infrarenal para-aortic nodes were associated with debulking status. Logistic regression determined a surgical predictive score which was able to significantly predict suboptimal debulking (n = 94, P = 0.0001) with an area under the curve (AUC) of 0.749 (95% confidence interval [95% CI]: 0.652, 0.846) and a sensitivity of 69.2%, specificity of 71.4%, positive predictive value of 75.0% and negative predictive value of 65.2%. These results remained significant in a recent validation set. There was a significant difference in residual disease volume in the test and validation sets (P < 0.001) in keeping with improved optimal debulking rates. CONCLUSIONS The presence of disease at some sites on preoperative CT scan is significantly associated with suboptimal debulking and may be an indication for a change in surgical planning.

Abstract
INTRODUCTION There is now a growing realization of the lack of experience of gynecological oncology trainees in gastrointestinal surgery. Advanced fellowship programs in gastrointestinal surgery have been suggested as a potential solution to this problem. PATIENTS AND METHODS We present data relating to gastrointestinal procedures performed by the gynecological oncology trainee during a fellowship program over a 3-year period in a single gynecological oncology center in the United Kingdom. RESULTS Over a 36-month period, 369 cases of invasive ovarian cancer were diagnosed in our institute, of which 278 (75.3%) were stage III/IV disease. Bowel surgery was performed in 86 patients (30.9%) with stage III/IV ovarian cancer. A total of 121 gastrointestinal procedures were performed during the study period, as some patients had more than one procedure. We present the procedures the gynecological oncology fellow performed and assisted during this period. DISCUSSION To improve competencies in performing bowel surgery among gynecological oncology trainees, we suggest sustained exposure in bowel surgery over the entire duration of the training program.
