Procalcitonin and C-reactive protein as early markers of anastomotic leakage in intestinal resections for advanced ovarian cancer (EDMOCS). Acta Obstet Gynecol Scand 2024; 103:1302-1310. [PMID: 38532280 PMCID: PMC11168259 DOI: 10.1111/aogs.14834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 02/29/2024] [Accepted: 03/02/2024] [Indexed: 03/28/2024]
Abstract
INTRODUCTION Serum levels of procalcitonin and C-reactive protein (CRP) have been used to predict anastomotic leakage after colorectal surgery, but information is scarce in advanced ovarian cancer (AOC) surgery with bowel resection. This study aimed to assess the predictive value of procalcitonin and CRP in detecting anastomotic leakage after AOC surgery with bowel resection. The study also aimed to determine the optimal postoperative reference values and the best day for evaluating these markers. MATERIAL AND METHODS This prospective, observational and multicentric trial included 92 patients with AOC undergoing debulking surgery with bowel resection between 2017 and 2020 in 10 reference hospitals in Spain. Procalcitonin and CRP levels were measured at baseline and on postoperative days 1-6. Receiver operating characteristic analysis was performed to evaluate the predictive value of procalcitonin and CRP at each postoperative day. Sensitivity, specificity, positive and negative predictive values were calculated. RESULTS Anastomotic leakage was detected in six patients (6.5%). Procalcitonin and CRP values were consistently higher in patients with anastomotic leakage at all postoperative days. The maximum area under the curve (AUC) for procalcitonin was observed at postoperative day 1 (AUC = 0.823) with a cutoff value of 3.8 ng/mL (83.3% sensitivity, 81.3% specificity). For CRP, the maximum AUC was found at postoperative day 3 (AUC = 0.833) with a cutoff level of 30.5 mg/dL (100% sensitivity, 80.4% specificity). CONCLUSIONS Procalcitonin and C-reactive protein are potential biomarkers for early detection of anastomotic leakage after ovarian cancer surgery with bowel resection. Further prospective studies with a larger sample size are needed to confirm these findings.

Abstract
The field of gynecologic oncology has witnessed a profound transformation in the practice of bowel resection over the years. This evolution, driven by innovative techniques and expanded surgical skills, has redefined the role of the surgeon. This review article delves into the historical journey of bowel surgery, its contemporary importance in cytoreductive procedures for gynecologic cancers, and the general principles of digestive surgery. From pioneering surgeons such as Lane, Broca, and Billroth to the introduction of mechanical staplers, this narrative unfolds the remarkable advances in the field. It highlights the critical need for meticulous training, anatomic mastery, aseptic measures, vascular support, tension-free anastomoses, and precise surgical techniques. These principles underpin the success of bowel resection and anastomosis in the complex landscape of gynecologic oncology.

Abstract
OBJECTIVE To assess the impact of short-term postoperative complications on oncologic outcomes for patients with epithelial ovarian cancer undergoing primary cytoreductive surgery (PCS) or interval cytoreductive surgery (ICS) with intestinal resection. METHODS A retrospective chart review was performed for patients with ovarian cancer who underwent PCS or ICS with at least one intestinal resection at our institution from 1/1/2015 to 12/31/2020. Progression-free survival (PFS) and overall survival (OS) were analyzed for the PCS and ICS cohorts separately. Short-term complications within 30 days of surgery (surgical secondary events [SSEs]) were graded by a validated institutional SSE system. RESULTS Among 437 patients who underwent intestinal resections during PCS (n = 289) or ICS (n = 148), 183 (42%) had one, 180 (41%) had two, and 74 (17%) had three intestinal resections. Six (1.4%) of 437 patients experienced an anastomotic leak postoperatively. There were no perioperative deaths. There was no difference in PFS and OS for patients who underwent PCS with any SSE vs. no SSE within 30 days of surgery (HR, 1.05; 95% CI: 0.76-1.47; p = 0.75 and HR, 0.79; 95% CI: 0.49-1.26; p = 0.32, respectively). There was no difference in PFS and OS for patients who underwent ICS with any SSE vs. no SSE within 30 days of surgery (HR, 1.43; 95% CI: 0.99-2.07; p = 0.055 and HR. 1.18; 95% CI: 0.72-1.93; p = 0.52, respectively. CONCLUSION Short-term postoperative morbidity for patients who underwent intestinal surgery during primary surgical management for advanced ovarian cancer did not impact oncologic outcomes.

Abstract
Ovarian cancer (OC) is the eighth most common cancer worldwide and is usually diagnosed in advanced stages. Despite many available data, no treatment results have been reviewed in Poland. This study enrolled 289 first-time patients treated between 2018 and 2021 by the Department of Oncology of the Poznań University of Medical Sciences (SKPP). The relationships among starting treatment in our centre, the type of first intervention, and the final decision were significant (p < 0.001). Patients in the SKPP group were more likely to primarily have a laparoscopy and less likely to have an exploratory laparotomy. Neoadjuvant chemotherapy (NACT) after a laparotomy was less often a final decision among SKPP patients (9% vs. 22%), in contrary to NACT after a laparoscopy (23% vs. 4%). Factors affecting the shortening of progression-free survival (PFS) were an advanced stage of the disease, a histopathological diagnosis, the type of cytoreduction, and the final decision. Significance according to the final decision was revealed for PDS vs. NACT after a laparotomy (p < 0.001) and for PDS vs. NACT after a laparoscopy (p = 0.011). Our study supports the benefits of treating ovarian cancer in an oncology centre with a high patient throughput. Further observations might also answer the question about overall survival (OS).

J Ovarian Res 2023; 16:85. [PMID: 37120533 PMCID: PMC10148549 DOI: 10.1186/s13048-023-01153-x] [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: 09/15/2022] [Accepted: 04/02/2023] [Indexed: 05/01/2023] Open
Abstract
BACKGROUND The aim of the study is to evaluate the risk factors of anastomotic leakage (AL) and develop a nomogram to predict the risk of AL in surgical management of primary ovarian cancer. METHODS We retrospectively reviewed 770 patients with primary ovarian cancer who underwent surgical resection of the rectosigmoid colon as part of cytoreductive surgery between January 2000 to December 2020. AL was defined based on radiologic studies or sigmoidoscopy with relevant clinical findings. Logistic regression analyses were performed to identify the risk factor of AL, and a nomogram was developed based on the multivariable analysis. The bootstrapped-concordance index was used for internal validation of the nomogram, and calibration plots were constructed. RESULTS The incidence of AL after resection of the rectosigmoid colon was 4.2% (32/770). Diabetes (OR 3.79; 95% CI, 1.31-12.69; p = 0.031), co-operation with distal pancreatectomy (OR, 4.8150; 95% CI, 1.35-17.10; p = 0.015), macroscopic residual tumor (OR, 7.43; 95% CI, 3.24-17.07; p = 0<001) and anastomotic level from the anal verge shorter than 10 cm (OR, 6.28; 95% CI, 2.29-21.43; p = 0.001) were significant prognostic factors for AL on multivariable analysis. Using four variables, the nomogram has been developed to predict anastomotic leakage: https://ALnomogram.github.io/ . CONCLUSION Four risk factors for AL after resection of the rectosigmoid colon are identified from the largest ovarian cancer study cohort. The nomogram from this information provides a numerical risk probability of AL, which could be used in preoperative counseling with patients and intraoperative decision for accompanying surgical procedures and prophylactic use of ileostomy or colostomy to minimize the risk of postoperative leakage. TRIAL REGISTRATION Retrospectively registered.

Abstract
INTRODUCTION Cytoreductive surgery (CRS) and intraperitoneal chemotherapy are effective in the treatment of ovarian peritoneal carcinomatosis (OPC). Colon resection is often required to achieve maximal cytoreduction during CRS. The success of complete mesocolic excision (CME) and total mesorectal excision (TME) in the surgical treatment of primary colorectal tumors is well-known. Our study aimed to investigate the factors affecting mesocolic lymph node metastasis (MLNM) and the contribution of CME/TME techniques to maximal cytoreduction in patients diagnosed with ovarian peritoneal carcinomatosis (OPC) with colon metastasis. PATIENTS AND METHODS Between 2004-2020, 30 patients who underwent colorectal resection with CME/TME techniques due to OPC-related colon metastasis were retrospectively analyzed. RESULTS The median age of patients was 61 (33-86). Six (20%) patients underwent total colectomy, 7 (23%) subtotal colectomy, 6 (20%) right hemicolectomy, 4 (13%) left hemicolectomy, and 7 (23%) rectosigmoid resection. Histopathological diagnosis was high-grade serous carcinoma in 29 (97%) patients, and malignant mixed Mullerian tumor in 1 (3%) patient. MLNM was detected in 17 (56%) of 30 patients. There was a significant relationship between MLNM and pelvic and para-aortic lymph node metastasis (PALNM) (p = 0.009) and lymphovascular invasion in primary ovarian tumors (p = 0.017). There was no significant relationship between MLNM and depth of colonic invasion (p = 0.463), histological grade (p = 0.711), and primary/secondary surgery (p = 0.638). MLNM was seen in 8 (47%) of 17 patients with only serosal invasion. CONCLUSION A high rate of MLNM can be seen in OPC-induced colon metastasis regardless of the degree of colon wall invasion. In patients with PALNM, the frequency of MLNM increases. We believe that if colon resection is to be performed in OPC, a colectomy should be performed by CME/TME principles to achieve maximal cytoreduction.

Abstract
We conducted an observational single-center cohort study on patients with recurrent high-grade serous ovarian carcinoma that underwent secondary surgical cytoreduction with extent of partial ileectomy and/or colectomy, followed by adjuvant chemotherapy (Paclitaxel-Carboplatin). All patients performed previously primary debulking surgery without residual disease, followed by three cycles of adjuvant chemotherapy. The aim of this study was to compare survival in patients with ostomy or end-to-end anastomosis that underwent secondary cytoreduction. Furthermore, we investigated the morbidity, the rate, timing and complications of the ostomy or end-to-end anastomosis after secondary cyto-reduction.

Abstract
Ovarian cancer is the most fatal of all female reproductive cancers. The fatality rate of OC is the highest among gynecological malignant tumors, and cytoreductive surgery is a common surgical procedure for patients with advanced ovarian cancer. To achieve satisfactory tumor reduction, intraoperative bowel surgery is often involved. Intestinal anastomosis is the traditional way to restore intestinal continuity, but the higher rate of postoperative complications still cannot be ignored. Transitory protective stoma can reduce the severity of postoperative complications and traumatic stress reaction and provide the opportunity for conservative treatment. But there are also many problems, such as stoma-related complications and the impact on social psychology. Therefore, it is essential to select appropriate patients according to the indications for the transitory protective stoma, and a customized postoperative care plan is needed specifically for the stoma population.

Abstract
Objective: to evaluate the incidence of anastomotic leakage (AL), risk factors and utility of drainage and stoma in patients undergoing intestinal surgery for ovarian cancer in a single institution and in a review of the literature. Methods: retrospective study that includes consecutive patients undergoing debulking surgery with en bloc pelvic resection with rectosigmoid colectomy for ovarian cancer between 1 November 2011 and 31 December 2021. Data regarding patient and tumour characteristics, surgical procedure, hospitalisation, complications and follow-up were recorded and analysed. The PubMed database was explored for recent publications on this topic. Results: Seventy-five patients were enrolled in the study. All anastomoses were performed at a distance of >6 cm from the anal margin, with negative leak tests and tension-free anastomosis. Diverting stoma were performed in just three patients (4%). At least one perianastomotic pelvic drain was positioned in 71 patients (94.7%) and was removed on average on postoperative day 7. Four patients (5.3%) experienced AL. In all cases, the drain content was not the only sign of complication, as the clinical signs were also highly suggestive. Just one patient received conservative treatment. Average postoperative hospitalisation was 14.6 days (SD: ±9.7). There were no deaths at 30 and 60 days after surgery. Between the AL and non-AL groups, statistically significant differences were observed for age, Charlson Comorbidity Index, length of the intestinal resection and fitness for chemotherapy at 30 days. In ovarian cancer, rectosigmoid resection is a standardised procedure with comparable results for AL, and risk factors for AL are discretely homogeneous. What is neither homogeneous nor standardised according to the literature is the use of stomas and/or drains. Conclusion: use in the future of protective stoma and/or intra-abdominal drains is to be explored in selected and standardised situations to verify their preventive role.

Abstract
Simple Summary Bowel resection is often required to obtain complete removal of ovarian cancer. A major complication of this operation is anastomotic leakage, which has been shown to increase morbidity and mortality in this population. Numerous original research studies have assessed the risk factors for anastomotic leaks. We aimed to conduct a systematic review and meta-analysis to identify statistically significant risk factors. This meta-analysis identified multiple bowel resections as the only significant risk factor. With further research to identify additional risk factors, new management guidelines could be implemented to minimize the risk of anastomotic leaks and improve patient outcomes. Abstract Introduction: Anastomotic leaks (AL) following ovarian cytoreduction surgery could be detrimental, leading to significant delays in commencing adjuvant chemotherapy, prolonged hospital stays and increased morbidity. The aim of this study was to investigate risk factors associated with anastomotic leaks after ovarian cytoreduction surgery. Material and methods: The MEDLINE (via PubMed), Cochrane Library, EMBASE and Scopus bibliographical databases were searched. Original clinical studies investigating risk factors for AL in ovarian cytoreduction surgery were included. Results: Eighteen studies with non-overlapping populations reporting on patients undergoing cytoreduction surgery for ovarian cancer (n = 4622, including 344 cases complicated by AL) were included in our analysis. Patients undergoing ovarian cytoreduction surgery complicated by AL had a significantly higher rate of 30-day mortality but no difference in 60-day mortality. Multiple bowel resections were associated with an increased risk of postoperative AL, while no association was observed with body mass index (BMI), American Society of Anesthesiologists (ASA) score, age, smoking, operative approach (primary versus interval cytoreductive, stapled versus hand-sewn anastomoses and formation of diverting stoma), neoadjuvant chemotherapy and use of hyperthermic intraperitoneal chemotherapy (HIPEC). Discussion: Multiple bowel resections were the only clinical risk factor associated with increased risk for AL after bowel surgery in the ovarian cancer population. The increased 30-day mortality rate in patients undergoing ovarian cytoreduction complicated by AL highlights the need to minimize the number of bowel resections in this population. Further studies are required to clarify any association between neoadjuvant chemotherapy and decreased AL rates.

Abstract
BACKGROUND Ovarian cancer is the seventh most common cancer among women and a leading cause of death from gynaecological malignancies. Epithelial ovarian cancer is the most common type, accounting for around 90% of all ovarian cancers. This specific type of ovarian cancer starts in the surface layer covering the ovary or lining of the fallopian tube. Surgery is performed either before chemotherapy (upfront or primary debulking surgery (PDS)) or in the middle of a course of treatment with chemotherapy (neoadjuvant chemotherapy (NACT) and interval debulking surgery (IDS)), with the aim of removing all visible tumour and achieving no macroscopic residual disease (NMRD). The aim of this review is to investigate the prognostic impact of size of residual disease nodules (RD) in women who received upfront or interval cytoreductive surgery for advanced (stage III and IV) epithelial ovarian cancer (EOC). OBJECTIVES To assess the prognostic impact of residual disease after primary surgery on survival outcomes for advanced (stage III and IV) epithelial ovarian cancer. In separate analyses, primary surgery included both upfront primary debulking surgery (PDS) followed by adjuvant chemotherapy and neoadjuvant chemotherapy followed by interval debulking surgery (IDS). Each residual disease threshold is considered as a separate prognostic factor. SEARCH METHODS We searched CENTRAL (2021, Issue 8), MEDLINE via Ovid (to 30 August 2021) and Embase via Ovid (to 30 August 2021). SELECTION CRITERIA We included survival data from studies of at least 100 women with advanced EOC after primary surgery. Residual disease was assessed as a prognostic factor in multivariate prognostic models. We excluded studies that reported fewer than 100 women, women with concurrent malignancies or studies that only reported unadjusted results. Women were included into two distinct groups: those who received PDS followed by platinum-based chemotherapy and those who received IDS, analysed separately. We included studies that reported all RD thresholds after surgery, but the main thresholds of interest were microscopic RD (labelled NMRD), RD 0.1 cm to 1 cm (small-volume residual disease (SVRD)) and RD > 1 cm (large-volume residual disease (LVRD)). DATA COLLECTION AND ANALYSIS Two review authors independently abstracted data and assessed risk of bias. Where possible, we synthesised the data in meta-analysis. To assess the adequacy of adjustment factors used in multivariate Cox models, we used the 'adjustment for other prognostic factors' and 'statistical analysis and reporting' domains of the quality in prognosis studies (QUIPS) tool. We also made judgements about the certainty of the evidence for each outcome in the main comparisons, using GRADE. We examined differences between FIGO stages III and IV for different thresholds of RD after primary surgery. We considered factors such as age, grade, length of follow-up, type and experience of surgeon, and type of surgery in the interpretation of any heterogeneity. We also performed sensitivity analyses that distinguished between studies that included NMRD in RD categories of < 1 cm and those that did not. This was applicable to comparisons involving RD < 1 cm with the exception of RD < 1 cm versus NMRD. We evaluated women undergoing PDS and IDS in separate analyses. MAIN RESULTS We found 46 studies reporting multivariate prognostic analyses, including RD as a prognostic factor, which met our inclusion criteria: 22,376 women who underwent PDS and 3697 who underwent IDS, all with varying levels of RD. While we identified a range of different RD thresholds, we mainly report on comparisons that are the focus of a key area of clinical uncertainty (involving NMRD, SVRD and LVRD). The comparison involving any visible disease (RD > 0 cm) and NMRD was also important. SVRD versus NMRD in a PDS setting In PDS studies, most showed an increased risk of death in all RD groups when those with macroscopic RD (MRD) were compared to NMRD. Women who had SVRD after PDS had more than twice the risk of death compared to women with NMRD (hazard ratio (HR) 2.03, 95% confidence interval (CI) 1.80 to 2.29; I2 = 50%; 17 studies; 9404 participants; moderate-certainty). The analysis of progression-free survival found that women who had SVRD after PDS had nearly twice the risk of death compared to women with NMRD (HR 1.88, 95% CI 1.63 to 2.16; I2 = 63%; 10 studies; 6596 participants; moderate-certainty). LVRD versus SVRD in a PDS setting When we compared LVRD versus SVRD following surgery, the estimates were attenuated compared to NMRD comparisons. All analyses showed an overall survival benefit in women who had RD < 1 cm after surgery (HR 1.22, 95% CI 1.13 to 1.32; I2 = 0%; 5 studies; 6000 participants; moderate-certainty). The results were robust to analyses of progression-free survival. SVRD and LVRD versus NMRD in an IDS setting The one study that defined the categories as NMRD, SVRD and LVRD showed that women who had SVRD and LVRD after IDS had more than twice the risk of death compared to women who had NMRD (HR 2.09, 95% CI 1.20 to 3.66; 310 participants; I2 = 56%, and HR 2.23, 95% CI 1.49 to 3.34; 343 participants; I2 = 35%; very low-certainty, for SVRD versus NMRD and LVRD versus NMRD, respectively). LVRD versus SVRD + NMRD in an IDS setting Meta-analysis found that women who had LVRD had a greater risk of death and disease progression compared to women who had either SVRD or NMRD (HR 1.60, 95% CI 1.21 to 2.11; 6 studies; 1572 participants; I2 = 58% for overall survival and HR 1.76, 95% CI 1.23 to 2.52; 1145 participants; I2 = 60% for progression-free survival; very low-certainty). However, this result is biased as in all but one study it was not possible to distinguish NMRD within the < 1 cm thresholds. Only one study separated NMRD from SVRD; all others included NMRD in the SVRD group, which may create bias when comparing with LVRD, making interpretation challenging. MRD versus NMRD in an IDS setting Women who had any amount of MRD after IDS had more than twice the risk of death compared to women with NMRD (HR 2.11, 95% CI 1.35 to 3.29, I2 = 81%; 906 participants; very low-certainty). AUTHORS' CONCLUSIONS In a PDS setting, there is moderate-certainty evidence that the amount of RD after primary surgery is a prognostic factor for overall and progression-free survival in women with advanced ovarian cancer. We separated our analysis into three distinct categories for the survival outcome including NMRD, SVRD and LVRD. After IDS, there may be only two categories required, although this is based on very low-certainty evidence, as all but one study included NMRD in the SVRD category. The one study that separated NMRD from SVRD showed no improved survival outcome in the SVRD category, compared to LVRD. Further low-certainty evidence also supported restricting to two categories, where women who had any amount of MRD after IDS had a significantly greater risk of death compared to women with NMRD. Therefore, the evidence presented in this review cannot conclude that using three categories applies in an IDS setting (very low-certainty evidence), as was supported for PDS (which has convincing moderate-certainty evidence).

Abstract
Background Cytoreductive surgery is currently the main treatment for advanced epithelial ovarian cancer (OC), and several surgical maneuvers, including colorectal resection, are often needed to achieve no residual disease. High surgical complexity carries an inherent risk of postoperative complications, including anastomosis leakage (AL). Albeit rare, AL is a life-threatening condition. The aim of this single-center retrospective study is to assess the AL rate in patients undergoing colorectal resection and anastomosis during primary surgery for advanced epithelial OC through a standardized surgical technique and to evaluate possible pre/intra- and postoperative risk factors to identify the population at greatest risk. Methods A retrospective analysis of clinical and surgical characteristics of 515 patients undergoing colorectal resection and anastomosis during primary or interval debulking surgery between December 2011 and October 2019 was performed. Several pre/intra- and postoperative variables were evaluated by multivariate analysis as potential risk factors for AL. Results The overall anastomotic leakage rate was 2.9% (15/515) with a significant negative impact on postoperative course. Body mass index < 18 kg/m2, preoperative albumin value lower than 30 mg/dL, section of the inferior mesenteric artery at its origin, and medium–low colorectal anastomosis (< 10 cm from the anal verge) were identified as independent risk factors for AL on multivariate analysis. Conclusions AL is confirmed to be an extremely rare but severe postoperative complication of OC surgery, being responsible for increased early postoperative mortality. Preoperative nutritional status and surgical characteristics, such as blood supply and anastomosis level, appear to be the most significant risk factors.

Abstract
Background To review the utilization of bowel resection in ovarian cancer surgery in our institution. Methods All ovarian cancer patients who received bowel resection between 2006/01 and 2018/12 were identified. Postoperative morbidities were assessed according to the Clavien–Dindo classification (CDC). Results There were 182 patients in the anastomosis group and 100 patients in the ostomy group, yielding a total of 282 patients. The median age was 57 years, and most patients had high-grade serous histology (88.7%). Forty-nine (17.3%) patients received neoadjuvant chemotherapy. During the operation, 78.7% of patients had ascites, and the median volume was 800 mL. Extensive bowel resection (at least two-segment) and upper abdominal operation were performed in 29 (10.2%) and 69 (24.4%) patients, respectively. The rectosigmoid colon was the most commonly resected (83.8%) followed by right hemicolectomy (5.9%) and small bowel resection (2.8%). No macroscopic residual disease was observed in 42.9% of the patients, whereas 87.9% had residual disease ≤ 1 cm. Among the entire cohort, 23.0% (65/282) experienced different complications. Severe complications (CDC 3–5) accounted for 9.2% of complications and were mostly categorized as pleural effusion requiring drainage (3.5%) followed by wound dehiscence requiring delayed repair in the operating room (1.8%). Nine patients experienced anastomotic leakage (AL): one in the ostomy group with extensive bowel resection and eight in the anastomosis group. The overall AL rate was 4.2% (9/212) per anastomosis. Conclusions The execution of bowel resection as part of debulking surgery in patients with newly diagnosed ovarian cancer resulted in a severe morbidity rate of 9.2%.

Abstract
OBJECTIVE To assess the benefit of protective ostomies on anastomotic leak rate, urgent re-operations, and mortality due to anastomotic leak complications in ovarian cancer surgery. METHODS A systematic literature search was performed in MEDLINE, Web of Science, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials for all studies on anastomotic leak and ostomy formation related to ovarian cancer surgery. Non-controlled studies, case series, abstracts, case reports, study protocols, and letters to the editor were excluded. Meta-analysis was performed on the primary endpoint of anastomotic leak rate. Subgroup analysis was carried out based on type of bowel resection and bevacizumab use. Secondary endpoints were urgent re-operations and mortality associated with anastomotic leak, length of hospital stay, postoperative complications, 30-day readmission rate, adjuvant chemotherapy, survival, and reversal surgery in ostomy and non-ostomy patients. RESULTS A total of 17 studies (2,719 patients) were included: 16 retrospective cohort studies, and 1 case-control study. Meta-analysis of 17 studies did not show a decrease in anastomotic leak rate in ostomy patients (odds ratio [OR]=1.01; 95% confidence interval [CI]=0.60-1.70; p=0.980). Meta-analysis of ten studies (1,452 women) did not find a decrease in urgent re-operations in the ostomy group (OR=0.72; 95% CI=0.35-1.46; p=0.360). Other outcomes were not considered for meta-analysis due to the lack of data in included studies. CONCLUSION Protective ostomies did not decrease anastomotic leak rates, and urgent re-operations in ovarian cancer surgery. This evidence supports the use of ostomies in very select cases.

Abstract
OBJECTIVE This systematic review and meta-analysis aimed to summarise the available evidence on the pre- and intra-operative risk factors for anastomotic leakage (AL) after bowel resection and anastomosis for ovarian cancer (OC). STUDY DESIGN We searched online databases from Pubmed, Scopus, ScienceDirect, and Cochrane Library from inception to October 2020. Pre- and intra-operative risk factors for AL were considered as the primary outcomes. Research heterogeneity and bias were evaluated by I2 and by the Newcastle Ottawa scale, respectively. The study was registered with PROSPERO, CRD42018095225. RESULTS The overall AL rate after OC surgery (median ± SD) was 5.3 ± 12% (277 AL on 5178 anastomoses). Thirteen non-randomised studies were included in the meta-analysis enrolling a total of 3274 patients. Pre albumin level ≤ 3 gr/dl, multiple bowel resections and primary cytoreductive surgery were associated with a significantly high risk of AL with a pooled OR of 5.29 (95% CI: 1.51-18.59), OR = 4.4 (95% CI: 1.19-16.66) and OR = 1.71 (95% CI: 1.05-2.77), respectively. Optimal cytoreduction, ASA score, ascites, and protective stoma were not associated with an increased risk of AL. CONCLUSION Based on the best available evidence, preoperative albumin level <3 gr/dl, multiple bowel resections and primary cytoreductive surgery were associated with an increased risk for AL after bowel surgery for OC.

Abstract
BACKGROUND Complete macroscopic resection without any residual tumour after completion of surgery is a strong prognostic factor in advanced epithelial ovarian cancer (EOC). It has previously been reported that surgery performed later in the week is associated with failure to achieve complete macroscopic resection. Our objective was to examine if weekday of surgery influences oncologic outcome. MATERIALS AND METHODS This population-based observational study included 100% of all women diagnosed with advanced-stage invasive epithelial ovarian cancer between 2009-2011 and 2014-2016 in the Stockholm/Gotland County of Sweden. The association between weekday of surgery and survival was analysed with proportional hazards regression yielding hazard ratios (HR) with 95% confidence intervals (CI), adjusted for predefined confounders. RESULTS Out of 1066 identified women, 524 with advanced stage EOC treated with surgery were included in the final analysis. Surgery performed Wednesday to Thursday was associated with an increased hazard of death (HR 1.28, 95% CI 1.04-1.58, p-value 0.02). The trend of the hazard of surgery performed throughout the week from Monday through Thursday was also significant (p = 0.01). CONCLUSION The increased mortality associated with surgery that is performed later in the week suggests that surgery for advanced ovarian cancer is best conducted early in the week.

Gynecol Oncol Rep 2021; 38:100870. [PMID: 34646929 PMCID: PMC8496105 DOI: 10.1016/j.gore.2021.100870] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 09/17/2021] [Accepted: 09/21/2021] [Indexed: 11/25/2022] Open
Abstract
Objectives To evaluate the impact of bowel resection at the time of interval cytoreductive surgery on survival. Methods We identified patients with advanced ovarian cancer who underwent neoadjuvant chemotherapy and interval cytoreductive surgery between 2008 and 2018 from a single-institution tumor registry. Kaplan-Meier survival analysis and Cox proportional hazards models were performed comparing patients who underwent bowel resection to those who did not. Results Of 158 patients, 43 (27%) underwent bowel resection. Rates of optimal (95%) and sub-optimal (5%) resection did not differ with bowel resection. Patients that required bowel resection had worse three-year survival (43% vs. 63%), even after adjusting for confounding variables of age, stage, number of neoadjuvant cycles, R0 resection, and ASA score (HR 2.27, p < 0.01). Adjusted progression-free survival did not differ between groups (HR 0.92, p = 0.72). Patients who underwent bowel resection were more likely to require blood transfusion (p < 0.01), and have a longer hospital stay (5 days vs 7.5 days, p < 0.01). Conclusions Bowel resection at the time of interval cytoreduction confers a greater than 2-fold increased risk of mortality and does not impact progression-free survival. Long-term sequelae of the peri-operative morbidity of bowel resection may contribute to increased mortality, and bowel resection may be a surrogate for disease biology with poor prognosis.

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.

Retroileal colorectal anastomosis after left-sided or transverse colectomy for advanced serous carcinoma of the ovary or uterus. Gynecol Oncol Rep 2021; 37:100834. [PMID: 34368413 PMCID: PMC8326726 DOI: 10.1016/j.gore.2021.100834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Revised: 06/25/2021] [Accepted: 07/13/2021] [Indexed: 11/23/2022] Open
Abstract
In advanced or recurrent ovarian and uterine cancer, the ability to achieve optimal cytoreduction is a prognostic factor. Colonic resections are commonly required to achieve minimal or no residual disease. The retroileal technique can be used to achieve complete gross resection in cytoreductive surgery for gynecologic malignancy. Lack of postoperative complications and acceptable time interval to return of bowel function suggest this technique is safe.
The ability to achieve complete or optimal cytoreduction in advanced or recurrent ovarian and uterine cancer is a well-established prognostic factor. Colonic resections are commonly required to achieve minimal or no residual disease. When multiple colonic resections are required there is a corresponding difficulty in obtaining sufficient colonic mobility to create tension-free anastomoses for restoration of gastrointestinal continuity; specifically, when a left hemicolectomy or a transverse colectomy is required in addition to a rectosigmoid resection, it may be difficult to achieve a tension-free colorectal anastomosis. We describe the use of retroileal routing of the colon to address this scenario in the context of gynecologic cancer debulking surgery. We report four cases in which the surgeon encountered limited colonic mobility after performing either a left hemicolectomy or a transverse colonic resection in addition to a rectosigmoid resection. In using a retroileal path to perform the colorectal anastomosis, we were able to achieve well-perfused and tension-free anastomoses. Complete gross resection was achieved in all four cases, with acceptable rates of perioperative complications.

Abstract
INTRODUCTION prediction and importance of severe postoperative complications after ovarian cancer surgery is a strong issue in patient selection and evaluation. Pre- and early peroperative predictors of severe 30-days postoperative complications (Clavien-Dindo class ≥3) after surgery for primary ovarian cancer are not fully established, neither their impact on patients' survival. MATERIALS AND METHODS A prospective observational study included 256 patients with primary ovarian cancer FIGO stages IIB-IV, operated during 2009-2018 in a primary or interval debulking surgery setting. Patient variables were analysed in relation to severe postoperative complications (Clavien-Dindo class ≥3) and overall survival. RESULTS High-grade postoperative complications occurred in 24.2% patients. Class 3a complications were observed in 12.5% cases. High-grade complications class ≥3 were observed in 31.6% after primary debulking surgery compared to 12.2% after interval debulking surgery (p = 0.0004). Peritoneal cancer index ≥21 and preoperative albumin concentration ≤33 g/L were independent predictors of high-grade complications. Peritoneal cancer index correlated with the surgical complexity score and completeness of cytoreduction. Increased peritoneal cancer index was a negative predictor of overall survival, but high-grade complications did not influence survival negatively. CONCLUSIONS Peritoneal cancer index ≥21 was an independent predictor of high-grade complications after ovarian cancer surgery. Increased peritoneal cancer index also impacted overall survival negatively, but high-grade complications did not influence overall survival.

Abstract
BACKGROUND Mesenteric lymph node (MLN) involvement is often observed in ovarian cancer (OC) with rectosigmoid invasion. This study aimed to investigate the clinical significance of MLN involvement in the pattern of liver metastasis in patients with OC. METHODS We included 85 stage II-IV OC patients who underwent primary or interval debulking surgery. Twenty-seven patients underwent rectosigmoid resection, whose status of MLN involvement was judged from hematoxylin and eosin (H&E) staining of resected specimens. The prognostic significance of clinicopathological characteristics, including MLN involvement, was evaluated using univariate and multivariate analyses. RESULTS MLN involvement was detected in 14/85 patients with stage II-IV OC. Residual tumor status, cytology of ascites, and MLN involvement were independent prognostic factors for progression-free survival (PFS; p = 0.033, p = 0.014, and p = 0.008, respectively). When patients were classified into three groups (no MLN, one MLN, two or more MLNs), the number of MLNs involved corresponded to three distinct groups in PFS (p = 0.001). The 3-year cumulative incidence of liver metastasis of patients with MLN involvement was significantly higher than that of patients without MLN involvement (61.1% vs. 8.9%, p < 0.001). MLN involvement was significantly associated with liver metastasis of hematogenous origin (p < 0.001) compared with peritoneal disseminated origin. CONCLUSION MLN involvement is an important prognostic factor in OC, predicting poor prognosis and liver metastasis of hematogenous origin.

Abstract
BACKGROUND To investigate whether rectosigmoid colectomy can improve the prognosis of patients with early-stage ovarian cancer when the ovarian tumor adheres to the rectum. METHODS We retrospectively studied 210 consecutive patients with stage I/II ovarian cancer treated between 2000 and 2016. The surgical strategy differed between the periods 2000-2007 and 2008-2016 with respect to adhesion between the ovarian tumor and rectum. In the former period, ovarian tumor was exfoliated from the rectum. Only when the residual tumor was apparently observed on the rectal surface after salpingo-oophorectomy with hysterectomy, it was subsequently removed by colorectal surgeons performing rectosigmoid colectomy. In the latter period, the ovarian tumor was resected en bloc with the rectum by performing rectosigmoid colectomy. We compared the progression-free survival (PFS) between the two treatment periods. RESULTS Rectosigmoid colectomy was performed more frequently in the latter period than in the former period (43 patients, 31% vs. 6 patients, 8%, p < 0.001). There was no significant difference in complete resection rate between the two periods (97% in the former period, 99% in the latter period, p = 0.278). However, the 5-year PFS rate was significantly higher in the latter period than in the former period (86.0% vs. 74.4%, log-rank test, p = 0.034). Multivariate Cox proportional-hazards regression analysis indicated that disease stage (hazard ratio [HR], 2.87, 95% confidence interval [CI] 1.14-7.34) and treatment period (HR 0.32, 95% CI 0.14-0.73) were independent risk factors for recurrence. CONCLUSIONS Rectosigmoid colectomy could improve the prognosis of patients with early-stage ovarian cancer when the ovarian tumor adheres to the rectum.

Abstract
Objective This study investigates the specific morbidity of rectosigmoid resection (RSR) during Visceral-Peritoneal Debulking (VPD) in a consecutive series of patients with stage IIIC-IV ovarian cancer and compares the results of the colo-rectal vs. the gynaecologic oncology team. Methods All patients with the International Federation of Gynecology and Obstetrics (FIGO) stage IIIC–IV ovarian cancer who had VPD and RSR were included in the study. Between 2009 and 2013 all operations were performed by the gynecologic oncology team alone (group 1). Since 2013 the RSR was performed by the colorectal team together with the gynecologic oncologist (group 2). All pre-operative information and surgical details were compared to exclude significant bias. Intra- and post-operative morbidity events were recorded and compared between groups. Results One hundred and sixty-two patients had a RSR during VPD, 93 in group 1 and 69 in group 2. Groups were comparable for all pre-operative features other than: albumin (1<2) hemoglobin (2<1) and up-front surgery (1>2). Overall morbidity was 33% vs. 40% (p=0.53), bowel specific morbidity 11.8% vs. 11.5% (p=0.81), anastomotic leak 4.1% vs. 6.1% (p=0.43) and re-operation rate 9.6% vs. 6.1% (p=0.71) in groups 1 and 2, respectively. None of them were significantly different. The rate of bowel diversion was 36.5% in group 1 vs. 46.3% in group 2 (p=0.26). Conclusions Our study failed to demonstrate any significant difference in the morbidity rate of RSR based on the team performing the surgery. These data warrant further investigation as they are interesting with regards to education, finance, and medico-legal aspects.

Abstract
High-grade serous ovarian carcinoma (HGSOC) is a leading cause of mortality among women worldwide. Currently, there is no clear consensus over the regime these patients should receive. The main two options are upfront debulking surgery with adjuvant chemotherapy or neoadjuvant chemotherapy followed by interval debulking surgery (IDS). The former approach is proposed to be accompanied by lower chemoresistance rates but could lead to severe surgical comorbidities and lower quality of life (QoL). Optimizing patient’s selection for upfront debulking surgery might offer higher progression-free and overall survival rates. Further studies need to be conducted in order to elucidate the predictive factors, which are favorable for patients undergoing upfront debulking surgery in cases of high-grade serous ovarian cancer.

Abstract
The objective of this study was to examine the rate of and indications for readmission in patients with advanced staged ovarian cancer undergoing rectosigmoid resection and primary anastomosis, an important quality metric. A retrospective review was conducted of patients with primary ovarian cancer who underwent rectosigmoid resection as part of cytoreductive surgery between July 2003 and July 2014. Univariate analysis identified rates and predictors of readmission. Fifty patients were eligible for analysis. The unanticipated 30-day readmission rate was 18% (n = 9). Of those readmitted less than 30 days from date of discharge, 3 were readmitted more than once, making 14 total readmissions. A total of 21 indications for readmission were reported, with the most common being: infection (23.8%, n = 5); thromboembolic events (19%, n = 4); and severe malnutrition (14.3%, n = 3). The median time to readmission was 14 days (range, 2-26). There were no deaths within 30 days of surgery in this cohort.IMPACT STATEMENTWhat is already known about the subject? Unanticipated 30-day readmission rates are reported to be between 12 and 20% among patients undergoing cytoreductive surgery for the management of ovarian cancer. The relative contribution of rectosigmoid resection at the time of cytoreductive surgery to readmission is not well studied.What do the results of this study add? In the examined cohort, the unanticipated 30-day readmission rate following rectosigmoid resection with primary reanastomosis at the time of cytoreductive surgery is 18%, similar to the readmission rate for patients undergoing cytoreductive surgery, in general. While the sample size is limited, the perioperative complications in this cohort appear similar to those of patients undergoing cytoreductive surgery.What are the implications of these findings for clinical practice and/or further research? Efforts to reduce unanticipated 30-day readmission following cytoreductive surgery is warranted. Future studies may benefit from multi-centre approaches and prospective data collection, while simultaneously assessing the impact of enhanced recovery programs. Ultimately, identification of risk factors, and programmatic initiatives to drive down readmission will be important across surgical platforms, and the opportunity exists in patients with advanced stage ovarian cancer.

Abstract
Objective: “En-bloc” resection of pelvic tumor in ovarian cancer (OC) is still controversial. The aim was to analyze results in an OC series from a single center, all of whom underwent “en-bloc” resection as part of cytoreductive surgery. Material and Methods: Clinical and surgical records from sixty patients with ovarian carcinoma who underwent “en-bloc” resection surgery were retrospectively analyzed. Results: Patients’ mean age was 56 years; 36 patients had primary disease and 24 had recurrent disease. Carcinomatosis was present in 46.7% of patients. Primary surgery was performed in 49 and interval debulking surgery in eleven. Complete cytoreduction was achieved in 55.0% and optimal in 38.3% of patients. Carcinomatosis significantly decreased the probability of complete cytoreduction [odds ratio (OR): 0.22; p=0.021]. Mesorectal infiltration occurred in 83% of patients. Risk of death was non-significantly higher (hazard ratio: 1.9) in women with mesorectal infiltration. Median overall survival was longer for patients without infiltration (46.1 vs 79.1 months; p=0.15). Eighty-five percent suffered from mild to moderate complications and colorectal anastomosis (CRA) leak occurred in two patients (3.6%) with CRA below 6 cm. Diaphragm resection had >5 times the risk for major complications (OR: 5.35; p=0.014). There was no three month mortality. Conclusion: When contiguous gross extension of disease to pelvic peritoneum and sigmoid colon is found, in patients with advanced OC, microscopic involvement of the mesorectum and intestinal wall is present in most cases making “en-bloc” resection necessary if complete cytoreduction is to be achieved. The associated morbidity is acceptable.

Abstract
OBJECTIVE To determine the factors related with diverting ileostomy performance after colorectal resection and anastomosis, in advanced ovarian cancer cytoreductive surgery. METHODS We have previously demonstrated the risk factors associated with anastomotic leak after colorectal anastomosis: Advanced age at surgery, low serum albumin level, additional bowel resections, manual anastomosis and distance of the anastomosis from the anal verge. However, use of diverting ileostomy is strongly variable and depends on individual surgeon preferences and training. Eight hospitals participated in this retrospective study. Data of 695 patients operated for ovarian cancer with primary colorectal anastomosis were included (January 2010-June 2018). Fourteen pre-/intraoperatively defined variables were identified and analysed as justification factors for use of diverting ileostomy. RESULTS The rate of diverting ileostomy in the entire cohort was 19.13% (133/695; range within individual centers 4.6-24.32%). Previous treatment with bevacizumab [OR 2.8 (1.3-6.1); p=0.01]; additional bowel resections [OR 3.0 (1.8-5.1); p<0.001]; extended operating time [OR 1.005 (1.003-1.006); p<0.001] and intra-operative red blood transfusion [OR 2.7 (1.4-5.3); p<0.001] were found to be independently associated with diverting ileostomy performance. Assuming a 7% AL rate cut-off, up to 51.8% of DI presented an AL risk below 7% and might have been spared. CONCLUSIONS The risk factors that drive the gynecologic oncology surgeons to perform a diverting ileostomy, seem to differ from the actual risk factors that we have identified to be associated with postoperative anastomotic leak. Broader awareness of the risk factors that contribute to a higher perioperative risk profile, will facilitate a better risk stratification process and possibly avoid unnecessary stoma formation in ovarian cancer patients.

The impact of near-infrared angiography and proctoscopy after rectosigmoid resection and anastomosis performed during surgeries for gynecologic malignancies. Gynecol Oncol 2020; 158:397-401. [PMID: 32460995 DOI: 10.1016/j.ygyno.2020.05.022] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Accepted: 05/13/2020] [Indexed: 01/06/2023]
Abstract
OBJECTIVES Reducing anastomotic leak rates after rectosigmoid resection and anastomosis is a priority in patients undergoing gynecologic oncology surgery. Therefore, we investigated the implications of performing near-infrared angiography (NIR) via proctoscopy to assess anastomotic perfusion at the time of rectosigmoid resection and anastomosis. METHODS We identified all patients who underwent rectosigmoid resection and anastomosis for a gynecologic malignancy between January 1, 2013 and December 31, 2018. NIR proctoscopy was assessed via the PINPOINT Endoscopic Imaging System (Stryker). RESULTS A total of 410 patients were identified, among whom NIR was utilized in 133 (32.4%). There were no statistically significant differences in age, race, BMI, type of malignancy, surgery, histology, FIGO stage, hypertension, diabetes, or preoperative chemotherapy between NIR and non-NIR groups. All cases of rectosigmoid resection underwent stapled anastomosis. The anastomotic leak rate was 2/133 (1.5%) in the NIR cohort compared with 13/277 (4.7%) in the non-NIR cohort (p = 0.16). Diverting ostomy was performed in 9/133 (6.8%) NIR and 53/277 (19.9%) non-NIR patients (p < 0.001). Postoperative abscesses occurred in 8/133 (6.0%) NIR and 44/277 (15.9%) non-NIR patients (p = 0.004). The NIR cohort had significantly fewer post-operative interventional procedures (12/133, 9.0% NIR vs. 55/277, 19.9% non-NIR, p = 0.006) and significantly fewer 30-day readmissions (14/133, 10.5% NIR vs. 61/277, 22% non-NIR, p = 0.004). CONCLUSIONS NIR proctoscopy is a safe tool for assessing anastomotic rectal perfusion after rectosigmoid resection and anastomosis, with a low anastomotic leak rate of 1.5%. Its potential usefulness should be evaluated in randomized trials in patients undergoing gynecologic cancer surgery.

Abstract
OBJECTIVE There are limited data on clinical outcomes of patients with advanced-stage epithelial ovarian cancer who require ostomy formation at the time of either primary cytoreductive surgery or interval cytoreductive surgery. The objective of this study was to evaluate patients undergoing bowel surgery and ostomy formation after primary or interval surgery. METHODS Patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIIC-IV epithelial ovarian cancer who underwent cytoreductive surgery between January 2010 and December 2014 were identified retrospectively. Patients with non-epithelial histology, low-grade serous histology or incomplete medical records were excluded. Demographic and clinical data were collected and analyzed. Age, stage, co-morbidity index, pre-operative CA125, pre-operative albumin, and Aletti surgical complexity score were included in a multivariable logistic regression model to assess independent associations with ostomy formation. RESULTS A total of 554 patients were included in the study. Of these, 261 (47%) underwent primary cytoreduction and 293 (53%) underwent interval cytoreduction. Patients undergoing primary surgery were more likely to undergo bowel resection, compared with interval surgery patients (37.2% vs 14%, p<0.001). Of the 139 (25.1%) patients who underwent bowel surgery, 25 (18%) underwent ostomy formation (11 ileostomies and 14 colostomies). Rates of ostomy formation were similar between the groups (6.1% primary vs 3.1% interval, p=0.10). Patients undergoing ostomy formation were more likely to have longer mean operative time (335 vs 229 min, p<0.001) and undergo small and large bowel resections at the time of cytoreductive surgery (44% vs 14%, p<0.001). Multivariate analysis revealed that a high surgical complexity score was associated with ostomy formation. Of the patients who underwent ostomy formation, 13 (43.3%) underwent stoma reversal including 11 ileostomies and two colostomies. Median time to ostomy reversal was 7 months. CONCLUSION Bowel surgery is more common among patients undergoing primary surgery as compared with interval surgery, but this does not result in an increased risk of ostomy formation.

Comparative study of three different managements after colorectal anastomosis in ovarian cancer: conservative management, diverting ileostomy, and ghost ileostomy. Int J Gynecol Cancer 2019; 29:1170-1176.

Abstract
ObjectiveAnastomotic leak remains the main concern after colorectal anastomosis in ovarian cancer. Our objective was to compare the use of three different management approaches after colorectal resection and anastomosis in patients with ovarian cancer.MethodsBetween January 2010 and June 2018, a total of 133 patients with International Federation of Gynecology and Obstetrics (FIGO) stage II–IV ovarian cancer who underwent colorectal resection and anastomosis were included. According to the approach followed after colorectal anastomosis and during the post-operative period, patients were stratified into three groups: conservative management and observation, diverting ileostomy, or ghost ileostomy technique. Univariate analyses were performed for quantitative variables by applying Student’s t test or Mann-Whitney U test and for qualitative variables by using the χ2 test (or Fisher’s test according to the sample size).ResultsA total of 145 patients underwent colorectal resection during cytoreduction for FIGO stage II–IV ovarian cancer. Twelve patients were excluded because a colostomy was required. Thus, 133 patients were included in the final analysis. Modified posterior pelvic exenteration was performed in 121 (91%) patients and recto-sigmoid resection in 12 (9%) patients with relapse. The approach after anastomosis was wait-and-see in 72 patients (54.1%), diverting ileostomy in 19 patients (14.4%), and ghost ileostomy in 42 patients (31.5%). There were no differences in diagnosis, age, body mass index, ECOG (Eastern Cooperative Oncology Group), histology, tumor grade, FIGO stage, or type of surgery between the groups. No differences were found regarding the anastomosis leak related factors or the rate of anastomotic leak between the three groups (5.6% vs 5.3% vs 4.8%; p=0.98). Two patients died because of the anastomotic leak in the wait-and-see group, and none died in the diverting ileostomy or ghost ileostomy group. In the diverting ileostomy group, a higher number of patients had complications compared with the ghost ileostomy group (78.9% vs 7.1%; p<0.01). Four patients (21.1%) developed dehydration due to high output stoma (>1500 mL) causing electrolyte imbalance in the diverting ileostomy group, and one patient (2.4%) in the ghost ileostomy group (p=0.03). The stoma reversal rate was 73.7% for the diverting ileostomy group and 100% for the ghost ileostomy group.ConclusionsThere were no differences found in the rate of anastomotic leak among the three groups of patients. The use of ghost ileostomy avoids the drawbacks of diverting ileostomy and seems to have advantages over routine diverting ileostomy and wait-and-see approaches for ovarian cancer patients undergoing colorectal anastomosis. Rates of stoma reversal are lower after diverting ileostomy when compared with ghost ileostomy.

Abstract
OBJECTIVE To determine pre-/intraoperative risk factors for anastomotic leak after modified posterior pelvic exenteration (MPE) or colorectal resection in ovarian cancer and to create a practical instrument for predicting anastomotic leak risk. BACKGROUND In advanced ovarian cancer surgery, there is rather limited published evidence, drawn from a small sample, providing information about risk factors for anastomotic leak. METHODS Eight hospitals participated in this retrospective study. Data on 695 patients operated for ovarian cancer with primary anastomosis were included (January 2010-June 2018). Twelve pre-/intraoperative variables were analysed as potential independent risk factors for anastomotic leak. A predictive model was created to stablish the risk of anastomotic leak for a given patient. RESULTS The anastomotic leak rate was 6.6% (46/695; range 1.7%-12.5%). A total of 457 patients were included in the final multivariate analysis. The following variables were found to be independently associated with anastomotic leakage: age at surgery (OR 1.046, 95% CI 1.013-1.080, p = 0.005), serum albumin level (OR 0.621, 95% CI 0.407-0.948, p = 0.027), one or more additional small bowel resections (OR 3.544, 95% CI 1.228-10.23, p = 0.019), manual anastomosis (OR 8.356, 95% CI 1.777-39.301, p = 0.007) and distance of the anastomosis from the anal verge (OR 0.839, 95% CI 0.726-0.971, p = 0.018). CONCLUSIONS Due to the low incidence of AL in ovarian cancer patients, a restrictive stoma policy based on the presence of risk factors should be the actual recommendation. Hand-sewn anastomosis should be avoided.

Abstract
Debulking surgery is the key step of advanced stage ovarian cancer treatment with chemotherapy. The quality of surgical resection is the main prognosis factor, thus a complete resection must be achieved (grade A) in an expert center (grade B). Surgery for stage IV is possible and has a benefit in case of complete peritoneal resection (LoE3). Pelvic and aortic lymphadenectomies are recommended in case of clinical or radiological suspicious lymph nodes (grade B). In absence of clinical or radiological suspicious lymph nodes and in case of complete peritoneal resection during initial debulking surgery, lymphadenectomy can be omitted because it won't change nor medical treatment nor overall survival (grade B). Neoadjuvant chemotherapy can be proposed in case of: impossibility to perform initial complete surgical resection (grade B) ; alteration of general state or co-morbidities or elderly patient (in order to decrease morbidity and increase quality of life) (grade B); stage IV with multiple intra-hepatic or pulmonary metastasis or important ascites with miliary (grade B). In case of stage III or IV ovarian cancer diagnosed on a biopsy during prior laparotomy, a neoadjuvant chemotherapy and interval debulking surgery should be preferred (gradeC). In case of palliative surgery or peroperative impossibility to perform a complete resection, no data regarding the type of surgery to perform influencing survival or quality of life is available. Peritoneal carcinosis description before resection and residual disease at the end of the surgery should be reported (size, location and reason of non-extirpability) (grade B). A score of peritoneal carcinosis such as Peritoneal Carcinosis Index (PCI) should be used in order to objectively evaluate the tumoral burden (gradeC). A standardized operative report is recommended (gradeC).

An increasing body of evidence has revealed that the aberrant expression of microRNAs (miRNAs/miRs) is involved in the development and progression of ovarian cancer (OC). miR-183 has been demonstrated to act as a tumor suppressor and oncogene in various types of human cancers. However, the biological role of miR-183 in OC still remains unclear. The aim of the present study was to investigate the role of miR-183 and evaluate its underlying mechanism in OC. In the present study, miR-183 was observed to be upregulated in OC tissues and cell lines as determined by reverse transcription-quantitative polymerase chain reaction. The effects of miR-183 on OC were further investigated via western blotting, MTT, wound healing, Transwell and immunofluorescence analyses. Downregulation of miR-183 markedly inhibited cell proliferation, migration and invasion, and promoted apoptosis in OC cells. Furthermore, it was initially confirmed that mothers against decapentaplegic homolog 4 (Smad4) was identified as an efficient target of miR-183 by luciferase activity assay. Finally, the results revealed that miR-183 directly regulated biological function via the transforming growth factor (TGF)-β/Smad4 signaling pathway in OC cells. In conclusion, the results of the present study suggested that miR-183 exerted tumor-promoting roles in OC, at least partially by regulating Smad4 via the TGF-β/Smad4 signaling pathway. Therefore, miR-183 may serve as a potential target for the diagnosis and prognosis of OC.

Abstract
To evaluate the mortality and morbidity related to bowel resection in women with advanced ovarian carcinoma. Retrospective case series of 47 women with stage III and IV carcinoma ovary who underwent bowel resection, over the period of 5 years from Jan 2011 to Dec 2015. The risk factors for perioperative morbidity and death were determined by regression analysis. The disease free and overall survival were determined by Kaplan-Meier plots. In this cohort, 64% (30/47) had primary debulking, 21% (10/47) had interval debulking, and 15% (7/47) had secondary debulking. The mean period of follow-up was 23 months (1 to 45 months). There were no anastomotic leaks. The commonest morbidities were relaparotomy (8.5%), surgical site infection (12%), and paralytic ileus (19%). The overall morbidity was 42.6% (20/47). The 30-day mortality was 4.2% (2/47). The recurrence rate was 51% (20/47). The overall mortality from ovarian cancer in this cohort was 40% (19/47) during the follow-up period. Stage and histology seemed to be important risk factors for morbidity. Low BMI and sub-optimal debulking were significant risk factors for recurrence and death in univariate analysis. Bowel resection, in optimally selected cases of advanced carcinoma ovary, is often required for optimal cytoreduction. It carries a reasonable peri-operative mortality and morbidity and improves overall survival.

Abstract
OBJECTIVE To assess the morbidity associate with rectosigmoid resection (RSR) in patients with stage IIIC-IV ovarian cancer (OC) undergone primary debulking surgery (PDS) vs. interval debulking surgery (IDS) after neoadjuvant chemotherapy (NACT). METHODS From the Oxford Advanced OC database, we retrieved all patients who underwent surgery between January 2009 and July 2016 and included all patients who underwent RSR. We compared the rates of overall related and not-related morbidity and bowel diversion in patients undergone RSR during PDS vs. IDS. RESULTS Three hundred and seventy-one patients underwent surgery: 126 in PDS group and 245 in IDS group. Fifty-two patients in the PDS group (41.3%) and 65 patients in IDS group (26.5%) underwent RSR (p<0.001). Overall not related morbidity rate was 37.5% and 28.6%, p=0.625. Bowel specific complications affected 16.3% vs. 11.1% of the patients (p=0.577). IDS group had higher rate of bowel diversion compared with PDS (46.0% vs. 26.5%, p=0.048). CONCLUSION NACT was associated to an overall reduced rate of RSR compared to IDS. No differences in overall related and not-related complications in patients requiring RSR were seen between the 2 groups. Patients in the IDS group had a significantly higher rate of bowel diversion.

Abstract
ObjectivesThe aims of this study were to assess anastomotic leakage (AL) rate and risk factors for AL in patients with advanced epithelial ovarian cancer (EOC) undergoing cytoreductive surgery including bowel resections and to evaluate the prognostic implication of AL.MethodsData of 350 consecutive patients with International Federation of Gynecology and Obstetrics EOC stage IIB–IV who underwent cytoreductive surgery at the Department of General Gynecology and Gynecologic Oncology of the General Hospital of Vienna between 2003 and 2017 were collected. Within this cohort, 192 patients (54.9%) underwent at least 1 bowel resection and were further analyzed. Preoperative risk factors for AL were computed using logistic regression models. Prognostic factors for overall survival were evaluated by using log-rank tests and multivariable Cox regression model.ResultsOverall, the AL rate was 4.7% for patients with advanced EOC undergoing cytoreductive surgery with at least 1 bowel resection, including patients with multiple large bowel resections. The AL rate for patients with isolated rectosigmoid resection was 1.9%. In univariate analysis, the number of anastomoses per surgery (P= 0.04) was associated with the occurrence of AL. In multivariable analysis, rectosigmoid resection with additional large bowel resection was associated with a higher risk of AL compared with isolated rectosigmoid resection (P= 0.046; odds ratio, 7.23 [95% confidence interval, 1.04–50.39]). Anastomotic leakage was associated with decreased overall survival (P= 0.04) in univariate but not in multivariable survival analysis.ConclusionsAnastomotic leakage rate after rectosigmoid resection in advanced EOC is acceptably low and outweighs increased perioperative risks when performed in a high-volume institution. Nonetheless, the occurrence of AL is a severe adverse event, which even seems to negatively affect patients’ overall prognosis. As no factor could be identified to clearly predict AL, extensive procedures comprising multiple bowel resections, should be avoided particularly when complete resection cannot be achieved.

Abstract
ObjectiveDiverting ileostomy (DI) has been proposed to reduce the incidence and consequences anastomotic leakage after bowel resection. In colorectal cancer treatment, ghost ileostomy (GI) has been proposed as an alternative to DI. Our objective was to report the results of GI associated with colorectal resection in the treatment of ovarian cancer.Materials and MethodsThis is an observational pilot study performed in a single institution. The main objective sought was to report the results of GI associated with colorectal resection in the treatment of ovarian cancer: 26 patients were included.ResultsModified posterior exenteration was performed in 24 cases (92.3%) and rectum resection in the 2 cases of relapse (7.7%). After the main procedure GI was created, to check up the anastomosis status, a sequential postoperative rectoscopy was performed on postoperative day 5 ± 1 (range, 4–7). Serum levels were monitored in first and third postoperative days just with a descriptive intention to establish its relationship with the rectoscopy findings. In 2 cases, rectoscopy demonstrated a leakage. During postoperative course, no other complication related with the GI or DI was observed. No case of clinical anastomotic leakage was found.ConclusionsTo the extent of our knowledge, this is the first study in which GI has been performed for the treatment of patients with ovarian cancer. Ghost ileostomy represents a real option that may reduce the number of ileostomies performed in ovarian cancer without increasing the morbimortality. Ghost ileostomy presents the advantages of DI while avoiding its drawbacks. It also seems to be a safe, feasible, and reproducible technique that does not add significant costs to the surgery.

Abstract
Objective To evaluate survival impact of low anterior resection (LAR) in patients with epithelial ovarian cancer (EOC) grossly confined to the pelvis. Methods We retrospectively reviewed 397 patients who underwent primary staging surgery for treatment of 2014 International Federation of Gynecology and Obstetrics (FIGO) stage II–IIIA EOC: 116 (29.2%) IIA, 212 (53.4%) IIB, and 69 (17.4%) IIIA. Patients with grossly enlarged retroperitoneal lymph nodes positive for metastatic carcinoma were excluded. Of 92 patients (23.2%) with gross tumors at the rectosigmoid colon, 68 (73.9%) underwent tumorectomy and 24 (26.1%), LAR for rectosigmoid lesions. Survival outcomes between patients who underwent tumorectomy and LAR were compared using Kaplan-Meier curves. Results During the median follow-up of 55 months (range, 1–260), 141 (35.5%) recurrences and 81 (20.4%) deaths occurred. Age (52.8 vs. 54.5 years, p=0.552), optimal debulking (98.5% vs. 95.0%, p=0.405), histologic type (serous, 52.9% vs. 50.0%, p=0.804), FIGO stage (p=0.057), and platinum-based adjuvant chemotherapy ≥6 cycles (85.3% vs. 79.2%, p=0.485) were not different between groups. No significant difference in 5-year progression-free survival (PFS; 57.9% vs. 62.5%, p=0.767) and overall survival (OS; 84.7% vs. 63.8%, p=0.087), respectively, was noted between groups. Postoperative ileus was more frequent in patients subjected to LAR than those who were not (4/24 [16.7%] vs. 11/373 [2.9%], p=0.001). The 5-year PFS (60.3% vs. 57.9%, p=0.523) and OS (81.8% vs. 87.7%, p=0.912) between patients who underwent tumorectomy and those who did not were also similar. Conclusion Survival benefit of LAR did not appear to be significant in EOC patients with grossly pelvis-confined tumors.

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
Ovarian cancer have a poor overall survival rate in patients, and late disease presentation and chemoresistance are the main factors that lead to the mortality of ovarian cancer. Cancer stem cells (CSCs), a small subpopulation of cancer cells, have been associated with resistance to chemo- and radio-therapy in cancer treatment. Hypoxia is a common characteristic of many malignant tumors, and increased HIF-1α expression predicts the poor prognosis of ovarian cancer. In this study, we reported the relationship between hypoxia and cancer stem cells-like properties in human ovarian cancer cell lines SKOV3 and HO8910, we found that hypoxia induced cancer stem cells-like properties in ovarian cancer cells. Moreover, SIRT1 was found to be the downstream target gene of HIF-1α, which was involved in the promotion of cancer stem cells-like features in ovarian cancer cells by hypoxia, and NF-κB signaling pathway was involved in hypoxia-induced SIRT1 up-regulation. Our results hinted that HIF1α and SIRT1 might serve as potential therapeutic targets for ovarian cancer.

Abstract
Cytoreductive surgery for patients with advanced epithelial ovarian cancer has been practised since the pioneering work of Tom Griffiths in 1975. Further research has demonstrated the prognostic significance of the extent of metastatic disease pre-operatively, and of complete cytoreduction post-operatively. Patients with advanced epithelial ovarian cancer should be referred to high volume cancer units, and managed by multidisciplinary teams. The role of thoracoscopy and resection of intrathoracic disease is presently investigational. In recent years, there has been increasing use of neoadjuvant chemotherapy and interval cytoreductive surgery in patients with poor performance status, which is usually due to large volume ascites and/or large pleural effusions. Neoadjuvant chemotherapy reduces the post-operative morbidity, but if the tumour responds well to the chemotherapy, the inflammatory response makes the surgery more difficult. Post-operative morbidity is generally tolerable, but increases in older patients, and in those having multiple, aggressive surgical procedures, such as bowel resection or diaphragmatic stripping. Primary cytoreductive surgery should be regarded as the gold standard for most patients until a test is developed which would allow the prediction of platinum resistance pre-operatively.

Abstract
Ovarian cancer is one of the most lethal malignant gynecologic tumors with a high relapse rate worldwide. Cancer stem cells (CSCs) have been identified in ovarian cancer and other malignant tumors as a small population of cells that are capable of self-renewal and multidifferentiation. CD133+ ovarian CSCs have been reported to be more tumorigenic and more resistant to chemotherapeutic treatment. Thus, CD133 has emerged as one of the most promising therapeutic markers for ovarian cancer treatment. In the current study, we constructed a recombinant adenovirus Cre/loxP regulation system to selectively introduce truncated Bid (tBid) expression specifically targeting CD133+ in ovarian CSCs. The results demonstrated that the coinfection of Ad-CD133-Cre and Ad-CMV-LoxP-Neo-LoxP-tBid significantly increased tBid expression in CD133+ ovarian CSCs. Moreover, the tBid overexpression induced by a recombinant adenovirus Cre/loxP system dramatically inhibited cell proliferation and invasion, significantly elevated cell apoptosis, and activated the mitochondrial apoptosis pathway in CD133+ ovarian CSCs. Additionally, recombinant adenovirus Cre/loxP system-mediated tBid overexpression suppressed the tumorigenic potential of CD133+ ovarian CSCs in a xenograft mouse model. In conclusion, our study successfully constructed a recombinant adenovirus Cre/loxP system and induced tBid overexpression in CD133+ ovarian CSCs, providing a new therapeutic approach for ovarian cancer treatment.

Abstract
Nowadays, the standard management of advanced epithelial ovarian cancer is correct surgical staging and optimal tumour cytoreduction followed by platinum and taxane-based chemotherapy. Standard surgical staging consists of peritoneal washings, total hysterectomy, and bilateral salpingo-oophorectomy, inspection of all abdominal organs and the peritoneal surface, biopsies of suspicious areas or randomised biopsies if they are not present, omentectomy and para-aortic lymphadenectomy. After this complete surgical staging, the International Federation of Gynaecology and Obstetrics (FIGO) staging system for ovarian cancer is applied to determine the management and prognosis of the patient. Complete tumour cytoreduction has shown an improvement in survival. There are some criteria to predict cytoreduction outcomes based on serum biomarkers levels, preoperative imaging techniques, and laparoscopic-based scores. Optimised patient selection for primary cytoreduction would determine patients who could benefit from an optimal cytoreduction and might benefit from interval surgery. The administration of intraperitoneal chemotherapy after debulking surgery has shown an increase in progression-free survival and overall survival, especially in patients with no residual disease after surgery. It is considered that 3–17% of all epithelial ovarian carcinoma (EOC) occur in young women that have not fulfilled their reproductive desires. In these patients, fertility-sparing surgery is a worthy option in early ovarian cancer.

Abstract
Wnt/β-catenin signaling pathway is strictly controlled by multiple negative regulators. However, how tumor cells override the negative regulatory effects to maintain constitutive activation of Wnt/β-catenin signaling, which is commonly observed in various cancers, remains puzzling. In current study, we reported that overexpression of miR-1207 in ovarian cancer activated Wnt/β-catenin signaling by directly targeting and suppressing secreted Frizzled-related protein 1 (SFRP1), AXIN2 and inhibitor of β-catenin and TCF-4 (ICAT), which are vital negative regulators of the Wnt/β-catenin pathway. We found that the expression of miR-1207 was ubiquitously upregulated in both ovarian cancer tissues and cells, which inversely correlated with patient overall survival. Furthermore, overexpression of miR-1207 enhanced, while silencing miR-1207 reduced, stem cell-like traits of ovarian cancer cells in vitro and in vivo, including tumor sphere formation capability and proportion of SP+ and CD133+ cells. Importantly, upregulating miR-1207 promoted, while silencing miR-1207 inhibited, the tumorigenicity of ovarian cancer cells. Hence, our results suggest that miR-1207 plays a vital role in promoting the cancer stem cell-like phenotype in ovarian cancer and might represent a potential target for anti-ovarian cancer therapy.
