Gynecol Oncol 2024; 188:97-102. [PMID: 38943693 DOI: 10.1016/j.ygyno.2024.06.021] [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: 03/21/2024] [Revised: 06/12/2024] [Accepted: 06/24/2024] [Indexed: 07/01/2024]
Abstract
BACKGROUND Advanced epithelial ovarian cancer (OC) patients often present with malnutrition; however, the ideal nutritional evaluation tool is unclear. We aimed to evaluate the role of preoperative albumin, Prognostic Nutritional Index [PNI], neutrophil-to-lymphocyte ratio [NLR], and platelet-to-lymphocyte ratio [PLR] as independent predictors of severe postoperative complications and 90-day mortality in OC patients who underwent primary cytoreductive surgery to identify the ideal tool. METHODS OC patients who underwent surgery at Mayo Clinic (2003-2018) were included; biomarkers were retrospectively retrieved and established cut-offs were utilized. Outcomes included severe complications (Accordion grade ≥ 3) and 90-day mortality. Univariate and multivariable logistic regression models were performed. Biomarkers were evaluated in separate models adjusted for age and American Society of Anesthesiologists (ASA) score for 90-day mortality, and adjusted for age, ASA score, stage, and surgical complexity for severe complications. RESULTS Albumin <3.5 g/dL, PNI < 45, NLR > 6 and PLR ≥ 200 were univariately associated with 90-day mortality (all p < 0.05) in 627 patients that met inclusion criteria. Each marker remained significant in adjusted models with albumin having the highest OR: 6.04 [95% CI:2.80-13.03] and AUC (0.83). Univariately, PNI <45, NLR >6, and PLR ≥200 were significant predictors of severe complications(all p < 0.05), however failed to reach significance in adjusted models. Albumin was not associated with severe complications. CONCLUSION All biomarkers were associated with 90-day mortality in adjusted models, with albumin being the easiest predictor to attain clinically; none with severe complications. Future research should focus less on methods of nutritional assessment and more on strategies to improve nutrition during OC tumor-directed therapy.

Impact of postoperative morbidity on outcomes in patients with advanced epithelial ovarian cancer undergoing intestinal surgery at the time of primary or interval cytoreductive surgery: A Memorial Sloan Kettering Cancer Center Team Ovary study. Gynecol Oncol 2023; 179:169-179. [PMID: 37992548 DOI: 10.1016/j.ygyno.2023.10.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 10/10/2023] [Accepted: 10/18/2023] [Indexed: 11/24/2023]
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.

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.

EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:468-474. [PMID: 36096854 DOI: 10.1016/j.ejso.2022.08.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 08/17/2022] [Accepted: 08/31/2022] [Indexed: 11/19/2022]
Abstract
INTRODUCTION A rectosigmoid resection with anastomosis is a common component of cytoreductive surgery for ovarian cancer. Evidence from colorectal studies suggests that end-to-side anastomoses may be associated with fewer complications than end-to-end approaches, but these have not previously been compared in an ovarian cancer patient cohort. MATERIALS AND METHODS Over a 51-month period, 239 patients underwent cytoreductive surgery for FIGO stage III/IV ovarian cancer. A rectosigmoid resection was performed in 79 (33.1%) with anastomosis in 59 (74.7%). Pre-operative and intra-operative factors associated with anastomotic leak, and post-operative complications were compared by anastomotic technique. RESULTS Anastomoses were end-to-end in 33 (55.9%) and end-to-side in 26 (44.1%) patients. There was a greater proportion of patients with a higher American Society of Anaesthesiologists score in the end-to-side group, but no other statistically significant differences in pre-or intra-operative factors between the groups. There were three (9.1%) cases of anastomotic leak in the end-to-end group, and no leaks in the end-to-side group, but the difference did not reach statistical significance. Both leaks were small, and successfully conservatively managed. There was no significant difference in rate of Clavien Dindo grade III/IV complications, although there was a higher rate of grade II complications following an end-to-side anastomosis (p = 0.036). There was no difference in length of stay, time to restarting chemotherapy, re-operation or 90-day mortality rate. CONCLUSION There was no significant difference in major morbidity following end-to-end or end-to-side anastomosis. Prospective randomised trials specifically focussed in ovarian cancer are needed.

Anastomotic Leak in Ovarian Cancer Cytoreduction Surgery: A Systematic Review and Meta-Analysis. Cancers (Basel) 2022; 14:cancers14215464.

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.

OVA-LEAK: Prognostic score for colo-rectal anastomotic leakage in patients undergoing ovarian cancer surgery. Gynecol Oncol 2022; 167:22-27.

Abstract
OBJECTIVE The objective of the present study was to define and validate an anastomotic leak prognostic score based on previously described and reported anastomotic leak risk factors (OVA-LEAK: https://n9.cl/ova-leakscore) and to establish if the use of OVA-LEAK score is better than clinical criteria (surgeon's choice) selecting anastomosis to be protected with a diverting ileostomy. MATERIAL & METHODS This is a retrospective, multicentre cohort study that included patients who underwent cytoreductive surgery for primary advanced or relapsed ovarian cancer with colorectal resection and anastomosis between January 2011 and June 2021. Data from patients already included in the previous predictive model were not considered in the present analysis. To validate the performance of our logistic regression model, we used the OVA-LEAK formula (Annex I: https://n9.cl/ova-leakscore) for estimating leakage probabilities in a new independent cohort. Then, receiver operating characteristic (ROC) analysis was performed and area under the curve (AUC) was used to measure the performance of the model. Additionally, the Brier score was also estimated. 95% confidence intervals (CI) for each of the estimated performance measures were also calculated. RESULTS 848 out of 1159 recruited patients were finally included in the multivariable logistic regression model validation. The AUC of the new cohort was 0.63 for predicting anastomotic leak. Considering a cut-off point of 22.1% to be 'positive' (to get a leak) this would provide a sensitivity of 0.45, specificity of 0.80, positive predictive value of 0.09 and negative predictive value of 0.97 for anastomotic leak. If we consider this cut-off point to select patients at risk of leak for bowel diversion, up to 22.5% of the sampled patients would undergo a diverting ileostomy and 47% (18/40) of the anastomotic leaks would be 'protected' with the stoma. Nevertheless, if we consider only the 'clinical criteria' for performing or not a diverting ileostomy, only 12.5% (5/40) of the leaks would be 'protected' with a stoma, with a rate of diverting ileostomy of up to 24.3%. CONCLUSIONS Compared with subjective clinical criteria, the use of a predictive model for anastomotic leak improves the selection of patients who would benefit from a diverting ileostomy without increasing the rate of stoma use.
