ObjectivesTo evaluate compliance with an Enhanced Recovery After Surgery (ERAS) protocol for open gynecologic surgery at a tertiary center and the relationship between levels of compliance and peri-operative outcomes.MethodsThis retrospective cohort study was conducted between November 2014 and December 2020. Two groups were defined based on compliance level (ResultsA total of 1879 patients were included. Overall compliance over the period of 6 years was 74% (95% CI 71.9% to 78.2%). Mean overall compliance increased from 69.7% to 75.8% between P1 and P3. Compliance with ERAS ≥80% was associated with lower Clavien–Dindo complication rates (grades III (OR 0.55; 95% CI 0.33 to 0.93) and V (OR 0.08, 95% CI 0.01 to 0.60)), 30-day re-admission rates (OR 0.61; 95% CI 0.43 to 0.88), and length of stay (OR 0.59; 95% CI 0.47 to 0.75). No difference in opioid consumption was seen. Pre-operatively, there was increased adherence to counseling by 50% (p=0.01), optimization by 21% (p=0.02), and carbohydrate loading by 74% (p=0.02). Intra-operatively, compliance with use of short-acting anesthetics increased by 37% (p=0.01) and avoidance of abdominal drainage increased by 7% (p=0.04). Use of goal-directed fluid therapy decreased by 16% (p=0.04). Post-operatively, there was increased compliance with avoiding salt and water overload (8%, p=0.02) and multimodal analgesia (5%, p=0.02).ConclusionsOver the time period of the study, overall compliance increased from 69.7% to 75.8%. Compliance (≥80%) with ERAS is associated with lower complication rates, fewer 30-day re-admissions, and shorter length of stay without impacting re-operation rates and post-operative opioid use.

ObjectivesTo evaluate whether the timing of postoperative urinary catheter removal is associated with voiding dysfunction after radical hysterectomy for early cervical cancer within contemporary surgical practice.MethodsWe performed an institutional retrospective cohort study of patients who underwent Piver type II-III open or minimally invasive radical hysterectomy for early-stage cervical cancer (International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IA1 with lymphovascular invasion to stage IIA) between January 2006 and December 2019. We compared voiding dysfunction (inability to spontaneously void with a post-void residual ResultsAmong 234 patients, 86 (36.8%) underwent open surgery and 112 (47.9%) used enhanced recovery after surgery (ERAS) pathways. 29 (12.4%) patients had urinary catheter removal between 1–5 days postoperatively (group 1), 141 (60.3%) between 6–10 days (group 2), and 64 (27.3%) between 11–15 days (group 3). The overall rate of voiding dysfunction was 11.5%, with no difference between group 1 (17.2%), group 2 (11.3%), and group 3 (9.4%) (p=0.54). Group 1 had a significantly shorter time from surgery to spontaneous voiding (4 days, IQR 3–5 days) compared with group 2 (8 days, IQR 7–10 days) and group 3 (13 days, IQR 11–15 days) (pConclusionThere was no difference in voiding dysfunction or postoperative genitourinary complications based on timing of urinary catheter removal after radical hysterectomy. Early catheter removal should be considered in this population.

ObjectiveCurrent gaps in knowledge limit clinicians from fully implementing patient-reported outcomes in routine post-operative care.MethodsThis prospective study assessed symptoms via the gynecologic module of the MD Anderson Symptom Inventory (MDASI-PeriOp-GYN) in patients who underwent open laparotomy.ResultsAt discharge, patient-reported moderate to severe (≥4 on a 0–10 scale) abdominal bloating or abdominal cramping, combined with length of stay of ≥4 days, were found to be associated with a higher risk of 30-day post-operative grade II–IV complications by the Clavien-Dindo system (all p values ConclusionThis study defined the clinically meaningful symptoms that related to the risk of developing important complications after discharge from major open gynecological surgery.These findings support the integration of assessment of patient-reported outcomes into patient-centered post-operative care.

OBJECTIVE: To determine the incidence of postoperative AKI after open gynecologic surgery within ERAS, compare AKI in pre-ERAS and ERAS cohorts, and identify factors associated with AKI. METHODS: We compared postoperative AKI in patients who underwent open gynecologic surgery at one institution before and after ERAS implementation. AKI was defined as acute risk, injury, or failure by RIFLE criteria. Pre-ERAS and ERAS cohorts were matched using propensity score analysis in a 1:1 fashion using the nearest neighbor technique. Chi-squared, Fisher’s Exact, and Wilcoxon rank-sum tests were used. RESULTS: Among 1334 ERAS and 191 pre-ERAS patients, postoperative AKI incidence was higher in the ERAS cohort (13.1% vs 5.8%, p=.004). In 166 matched pairs, ERAS patients had higher incidence (16.9% vs 5.4%, p5 minutes (41.7% vs 30.7%, p

ObjectiveOpen surgery has become the standard approach for radical hysterectomy in early stage cervical cancer (International Federation of Gynecology and Obstetrics (FIGO) 2018 IA1 with lymphovascular space invasion-IIA1). Our primary objective was to compare the length of stay in patients undergoing open radical hysterectomy before and after implementation of an enhanced recovery after surgery (ERAS) program.MethodsThis was a single center, retrospective, before-and-after intervention study including patients who underwent open radical hysterectomy for cervical cancer from January 2009 to December 2020. Two groups were identified based on the time of ERAS implementation: pre-ERAS group included patients who were operated on between January 2009 and October 2014; post-ERAS group included patients who underwent surgery between November 2014 and December 2020.ResultsA total of 81 patients were included, of whom 29 patients were in the pre-ERAS group and 52 patients in the post-ERAS group. Both groups had similar clinical characteristics with no differences in terms of median age (42 years (interquartile range (IQR) 35–53) in pre-ERAS group vs 41 years (IQR 35–49) in post-ERAS group; p=0.47) and body mass index (26.1 kg/m2 (IQR 24.6–29.7) in pre-ERAS group vs 27.1 kg/m2 (IQR 23.5–33.5) in post-ERAS group; p=0.44). Patients in the post-ERAS group were discharged from the hospital earlier compared with those in the pre-ERAS group (median 3 days (IQR 2–3) vs 4 (IQR 3–4), pConclusionsPatients undergoing open radical hysterectomy on an ERAS pathway have a shorter length of hospital stay without increasing overall complications or readmissions rates.

Objectives As part of a study to construct a shared-medical decision tool for ovarian cancer maintenance therapy (MT), we developed a knowledge survey to measure patients’ understanding of their cancer and treatment. With the recent expansion of MT indications, patients need to decide if MT is right for them. An understanding of potential risks and benefits associated with MT is paramount to making an informed decision. We explored knowledge differences between newly diagnosed and recurrent patients. Methods A 32-question survey focused on ovarian cancer (OC) and MT was developed based on interviews with patients and subject matter experts. The survey was modified iteratively using cognitive interviews with patients. Patients with OC with ≥ 3 cycles of chemotherapy and cytoreductive surgery completed the survey by email or phone. No prior background information was given to patients. Results Clinico-demographic characteristics are shown in table 1 (n=87). Sixty percent had recurrent disease. General knowledge about advanced OC was similar between groups. The majority of patients did not understand the purpose of MT or the definition of progression-free survival. The recurrent group showed a similar lack of knowledge in the same questions as the newly diagnosed group, with no statistically significant differences observed (figure 1). Conclusions Our data suggests that knowledge of OC among patients is highly variable. The overall lack of understanding regarding the goal of MT even among patients who have recurred is concerning. These gaps in knowledge suggest an important role for shared decision making to improve patients’ decision making about treatment of advanced OC.

Introduction/Background* Open approach has become the standard for many institutions when performing a radical hysterectomy for early cervical cancer. The objective of this study was to evaluate the length of stay after open radical hysterectomy before and after the implementation of Enhanced Recovery After Surgery (ERAS) pathway in a tertiary cancer center. Methodology This is a retrospective study of patients who underwent open radical hysterectomy for cervical cancer from January 2009 to December 2020. We distinguished two groups based on the time of ERAS implementation: group 1 (pre-ERAS) between January 2009 and October 2014 and group 2 (post-ERAS) between November 2014 and December 2020. We also defined two time periods according to the application of open radical hysterectomy as a standard of care. Univariate analysis was applied and P values were reported using chi-squared or Fisher’s exact test. Result(s)* A total of 81 patients were included; 29 patients in group 1 and 52 patients in group 2. There were no differences in terms of age (median of 42 years [35-53] in group 1 vs 41 years [35-49] in group 2; p=0.47) and BMI (26.1 kg/m2 [24.6-29.7-53] in group 1 vs 27.1 in kg/m2[23.5-33.5] in group 2; p=0.44). Patients in group 2 were discharged from the hospital earlier compared to group 1 (median 3 days [2-3] vs 4 days [3-5], p Conclusion* Patients undergoing an open radical hysterectomy under an ERAS pathway have a decreased length of hospital stay without increasing overall complications nor readmissions rate.

OBJECTIVE. To identify clinical and demographic characteristics associated with the absence of opioid usage on the day before discharge among patients undergoing open gynecologic surgery within an enhanced recovery after surgery (ERAS) program. METHODS. This was a single institution retrospective cohort study including all patients who underwent elective open gynecologic surgery as part of an ERAS program between November 1, 2014 and September 30, 2018 and who were discharged between post-operative day 2 and 7. Patients were excluded if they reported preexisting chronic opioid use or underwent total pelvic exenteration. Descriptive statistics were used and multivariable logistic regression was used to identify factors associated with the absence of opioid usage on the day before discharge, after adjustment for relevant covariates. RESULTS. A total of 971 were included with a median length of stay of 3 days, and of these 526 (54.2%) used opioids on day before discharge and 445 (45.8%) did not. Absence of opioid use on the day before discharge was associated with age (P < .001), race (P = .04), Charlson Co-morbidity Index (P < .001), marital status (P = .004), and smoking status (P = .002) by univariate analysis. In a multivariable model, older age (adjusted OR 1.04; 95% CI 1.02–1.06; P < .001), current smoker status (adjusted OR 0.42; 95% CI 0.20–0.81; P = .01), and white or Caucasian race (adjusted OR 0.59; 95% CI 0.38–0.91; P = .02) were significantly associated with the absence of opioid use on the day prior to discharge. CONCLUSIONS. Nearly half of patients undergoing open gynecologic surgery within an established ERAS program did not consume any opioids on day before discharge. Safe, evidence-based reductions in post-operative opioid prescribing may be feasible for a subset of gynecologic surgery patients.

BackgroundThis is the first updated Enhanced Recovery After Surgery (ERAS) Society guideline presenting a consensus for optimal perioperative care in gynecologic/oncology surgery.MethodsA database search of publications using Embase and PubMed was performed. Studies on each item within the ERAS gynecologic/oncology protocol were selected with emphasis on meta-analyses, randomized controlled trials, and large prospective cohort studies. These studies were then reviewed and graded according to the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system.ResultsAll recommendations on ERAS protocol items are based on best available evidence. The level of evidence for each item is presented accordingly.ConclusionsThe updated evidence base and recommendation for items within the ERAS gynecologic/oncology perioperative care pathway are presented by the ERAS® Society in this consensus review.

Objective To compare symptom burden and functional recovery in women undergoing primary cytoreductive surgery (PCS) or neoadjuvant chemotherapy (NACT) and interval cytoreductive surgery (ICS) within an enhanced recovery after surgery program (ERAS). Methods Symptom burden was measured using the MD Anderson Symptom Inventory-Ovarian Cancer, a 27-item validated tool that was administered preoperatively, daily while hospitalized, and weekly for 8 weeks after hospital discharge. Mixed-effect modeling was performed. Results 196 patients (71 PCS, 125 ICS) participated. Patients in the PCS group were younger, median age of 59 vs. 63 in ICS group. Median length of stay was 4 days for PCS and 3 days for ICS group. PCS pts had a significantly higher median surgical complexity score (4 vs. 2, p = 0.002), and longer median surgical time (257 min vs. 220 min, p = 0.03). While patients undergoing PCS had significantly different symptom burden profiles prior to surgery compared to those undergoing ICS, there were no significant differences in symptoms in the immediate in-hospital and extended post-hospital discharge period. Irrespective of the timing of surgery in relation to chemotherapy, patients undergoing intermediate or high complexity surgery had more nausea, fatigue, and higher total interference scores compared to patients undergoing low complexity surgery. Conclusion Within a center with a standardized, systematic method for patient selection for PCS and a standardized ERAS care pathway, there were not significant differences in surgery-related symptoms related to recovery between patients undergoing PCS or ICS. However, patient-reported symptom burden and symptom interference did meaningfully differentiate based on surgical complexity score.

OBJECTIVE: Using patient-reported outcomes (PROs) in perioperative care is increasingly common. We report the development, validation, and application of an MD Anderson Symptom Inventory version for use in patients undergoing surgery for gynecologic cancer or benign conditions (MDASI-PeriOp-GYN). METHODS: Our process included: (1) generating PeriOp-GYN–specific candidate items from qualitative interviews with patients, followed by input from an expert panel; (2) dropping items that lacked independent clinical relevance; (3) validating psychometric properties (reliability, validity) of the resulting MDASI-PeriOp-GYN; and (4) conducting cognitive debriefing interviews with patients to confirm ease of comprehension, relevance, and acceptability. RESULTS: Qualitative interviews with 40 patients generated 9 new PeriOp-GYN symptom items (bloating, abdominal cramping, constipation, hot flashes, dizziness, grogginess/confusion, urinary pain, difficulty urinating, and diarrhea) that, along with the core MDASI items, formed the new MDASI-PeriOpGYN. A total of 150 patients (minimally invasive surgery (MIS)=69, open surgery=81) participated in the validation study; 123 also provided retest data. Cronbach alphas were 0.89 for symptoms and 0.86 for interference. Test-retest reliability was 0.88 for all symptom severity items. Known-group validity was supported by the detection of significant differences in symptom and interference levels by performance status (P

Background: With increasing implementation of enhanced recovery programs (ERPs) in clinical practice, standardised data collection and reporting have become critical in addressing the heterogeneity of metrics used for reporting outcomes. Opportunities exist to leverage electronic health record (EHR) systems to collect, analyse, and disseminate ERP data. Objectives: (i) To consolidate relevant ERP variables into a singular data universe; (ii) To create an accessible and intuitive query tool for rapid data retrieval. Method: We reviewed nine established individual team databases to identify common variables to create one standard ERP data dictionary. To address data automation, we used a third-party business intelligence tool to map identified variables within the EHR system, consolidating variables into a single ERP universe. To determine efficacy, we compared times for four experienced research coordinators to use manual, five-universe, and ERP Universe processes to retrieve ERP data for 10 randomly selected surgery patients. Results: The total times to process data variables for all 10 patients for the manual, five universe, and ERP Universe processes were 510, 111, and 76 min, respectively. Shifting from the five-universe or manual process to the ERP Universe resulted in decreases in time of 32% and 85%, respectively. Conclusion: The ERP Universe improves time spent collecting, analysing, and reporting ERP elements without increasing operational costs or interrupting workflow. Implications: Manual data abstraction places significant burden on resources. The creation of a singular instrument dedicated to ERP data abstraction greatly increases the efficiency in which clinicians and supporting staff can query adherence to an ERP protocol.

Introduction Enhanced recovery after surgery (ERAS) pathways use goal-directed fluid therapy (GDT) to reduce postoperative complications from fluid imbalance. Our study aimed to determine the incidence and risks of acute kidney injury (AKI) in patients on an ERAS pathway. Methods AKI was defined as acute risk, injury, or failure by RIFLE criteria. Chi-squared, Fisher’s Exact, and Wilcoxon rank-sum tests were used. Propensity score analysis with 1:1 matching compared AKI in ERAS and pre-ERAS cohorts and modeled the probability of AKI as a function of ERAS. Results Among 1127 patients on an ERAS pathway, 140 had AKI (12.4%, 95% CI 10.5%-14.5%). Patients with AKI were more likely to be older (median age 65 vs 57, p Conclusions A total of 12.4% of patients developed AKI, but ERAS itself was not associated with AKI incidence in the matched cohort. Highest AKI risk factors included older age, black race, more comorbidities, and blood loss.

OBJECTIVE: To evaluate the utility of patient-reported outcomes (PROs) to measure physical functioning in perioperative care for patients with gynecological (GYN) tumors. METHODS: 180 patients with GYN tumors undergoing open surgery participated in this longitudinal study. The physical functioning was measured by a subjective PRO tool, the Interference subscales of the MD Anderson Symptom Inventory (MDASI-I); as well as by an objective tool, the Timed Up & Go test (TUGT), perioperatively. Longer time (>20 seconds) needed to complete the TUGT was defined as “Prolonged”. Patients completed EuroQoL-5D as well. The association between the scores of MDASI-I items and TUGT was assessed via the Spearman correlation coefficient. The known-group validity was assessed using the t-test and Cohen’s D effect size. RESULTS: Compliance rates at preoperative, discharge and postoperative time points of MDASI-I were 98%, 95%, 96%; while TUGT completion rates were 92%, 75%, and 80%, respectively. Patients who had refused TUGT at discharge reported a significantly worse “MDASI-general activity” score compared to patients who completed TUGT (mean score of 7.00 vs. 5.38, P=0.020). Patient-reported “Walking” on MDASI-I significantly differentiated patients with prolonged vs. those with frail/normal TUGT at discharge (mean score of 4.89 vs. 2.79, Cohen’s d effect size = 0.82, P < 0.001) MDASI-I demonstrated excellent known-group validity per performance status and for the EuroQoL-5D subscales. CONCLUSION: Patient-reported physical functioning impairment after GYN surgery correspond with observed worse scores of the objective functioning measure test (TUGT). MDASI-I assessment represents a feasible and valid tool to evaluate functional status and warrants further implementation in the perioperative setting.

ObjectiveTo determine post-discharge patient-reported symptoms before and after implementation of restrictive opioid prescribing among women undergoing minimally invasive gynecologic surgery.MethodsWe compared clinical outcomes and symptom burden among a cohort of 389 women undergoing minimally invasive gynecologic surgery at a single institution before and after implementation of a restrictive opioid prescribing quality improvement initiative in July 2018. Post-discharge symptom burdens were collected up to 42 days after discharge using the MD Anderson Symptom Inventory and analyzed using linear mixed effects models.ResultsThe majority of women included in this study were white non-smokers and the median age was 55 (range 23–83). Most women underwent hysterectomy (64%), had surgery for malignancy (71%), and were discharged from the hospital on the day of surgery (65%). Women in the restrictive opioid prescribing group had a median reduction in morphine equivalent dose prescribed at discharge of 83%, corresponding to a median reduction in 25 tablets of 5 mg oxycodone per person. There was no difference between opioid prescribing groups in either the rate of refill requests (P=1) or hospital re-admission (P=1) up to 30 days after discharge. After adjustment for co-variates, there was no statistically significant difference in post-discharge symptom burden including patient-reported pain (P=0.08), sleep (P=0.30), walking interference (P=0.64), activity interference (P=0.12), or affective interference (P=0.67). There was a trend toward less reported constiptation in the restrictive opioid prescribing group that did not reach statistical significance (P=0.05).ConclusionWe found that restrictive post-operative opioid prescribing was not associated with differences in longitudinal symptom burden among women undergoing minimally invasive gynecologic surgery. These results provide the most comprehensive picture to date of post-operative symptom recovery under different opioid prescribing approaches, lending additional support for existing recommendations to reduce opioid prescribing following gynecologic surgery.

ObjectiveTo compare post-operative length of stay and complication rates of matched obese and non-obese patients in an enhanced recovery (ERAS) program after open gynecologic cancer surgery.MethodsWe performed an observational cohort study of patients (n=1225) undergoing open surgery from November 2014 to November 2018 at a tertiary cancer center. Patients undergoing multidisciplinary procedures, non-oncologic surgery, or procedures in addition to abdominal surgery were excluded (n=190). Obese and non-obese patients were matched by date, age, disease status, and surgical complexity. The primary outcome was post-operative length of stay. Secondary outcomes included 30-day peri-operative complications, re-operation, re-admission, opioid use, and program compliance.ResultsAfter matching, 696 patients (348 obese, 348 non-obese) with median age of 57 years (IQR 48–66) were analyzed. Obese patients had a longer median procedure time (218 min vs 192.5 min, pConclusionsNeither post-operative length of stay nor the rate of serious complications differed significantly despite longer surgeries, greater blood loss, and more opioid use among obese patients. An ERAS program was safe, effective, and feasible for obese patients with suspected gynecologic cancer.

Ovarian cancer is the leading cause of death from gynecologic malignancy and the fifth cause of cancer death in women in the United States. The most common and lethal histologic subtype of epithelial ovarian cancer is high-grade serous carcinoma (HGSC), which generally presents at an advanced stage. HGSC may be associated with BRCA1 and BRCA2 mutations. Historically, HGSC was believed to originate from the ovarian epithelial cells. However, more recent evidence supports the idea that most ovarian cancers originate in the fallopian tube epithelium in both high-risk women and in the general population. Serous tubal intraepithelial carcinomas may ultimately evolve into ovarian or peritoneal cancer. As a result, prophylactic salpingectomy with conservation of the ovaries has become an increasingly more common practice for premenopausal women undergoing risk-reducing surgery. Because the fallopian tube is now recognized as the most common potential site of origin of ovarian carcinoma, there is ongoing research to explore molecular and genetic factors that may be critical in the development of this disease. Further research is needed to identify novel opportunities for early detection and screening of ovarian cancer with the ultimate goal of increasing overall survival.

ObjectiveThe aim of this study was to evaluate if varying levels of compliance with an enhanced recovery after surgery (ERAS) protocol impacted post-operative outcomes (length of stay, complications, readmissions, and re-operations) in gynecologic surgery at a tertiary center.MethodsWe included 584 patients who had open gynecologic surgery between November 1, 2014 and December 31, 2016. Patients were categorized into subgroups according to their date of surgery from the time of the ERAS protocol implementation. Patients were categorized by their per cent compliance into two groups:ResultsOverall compliance was 72.3%. Patients with compliance ≥80% had significantly less complications (PConclusionsCompliance with an ERAS pathway exceeding 80% was associated with lower complication rates and shorter length of stay without impacting on re-operations or readmissions.

Background Value in healthcare is reflected by patient-centered outcomes of care per health dollar expended. Although liposomal bupivacaine is more expensive, it has been shown to provide prolonged analgesia (up to 72 hours). Objective This study aimed to evaluate whether the addition of liposomal bupivacaine to standard bupivacaine could decrease opioid intake and improve pain control after laparotomy for gynecologic surgery compared with standard bupivacaine alone in an enhanced recovery after surgery pathway. Study Design A prospective randomized controlled single-blinded trial of wound infiltration with liposomal bupivacaine plus 0.25% bupivacaine (study arm) vs 0.25% bupivacaine (control arm) was performed at a National Cancer Institute–designated tertiary referral cancer center. Participants were patients aged ≥18 years undergoing exploratory laparotomy for a gynecologic indication. All patients were treated on an enhanced recovery pathway including local wound infiltration before closure. In this study, 266 mg of liposomal bupivacaine (free base; equal to 300 mg bupivacaine HCL)+150 mg of bupivacaine mixed in the same syringe was used in the study arm, and 150 mg of bupivacaine was used in the control arm. The primary outcome was the proportion of patients who were opioid-free within 48 hours after surgery. Secondary outcomes included number of opioid-free days from postoperative day 0 to postoperative day 3, days to first opioid administration, morphine equivalent daily dose, and patient-reported outcomes collected with the MD Anderson Symptom Inventory. The MD Anderson Symptom Inventory was administered as a preoperative baseline, daily while hospitalized, and at least weekly for 8 weeks after discharge. All outcomes were prespecified before data collection. Results In this study, 102 patients were evaluated. Among them, 16.7% of patients in the study arm received no opioids up to 48 hours compared with 14.8% in the control arm (P=.99). There were no significant differences in the amount of intraoperative opioids administered or days to first opioid use. There was no significant difference between the 2 arms in median cumulative morphine equivalent daily dose (21.3 [study arm] vs 33.8 [control arm]; P=.36) or between the groups in morphine equivalent daily dose per individual day. There were no significant differences in patient-reported pain or interference with walking between the 2 arms or other patient-reported outcomes. Conclusion Within an enhanced recovery after surgery pathway, adding liposomal bupivacaine to 0.25% bupivacaine wound infiltration did not decrease the proportion of patients who were opioid-free within 48 hours after surgery, did not decrease opioid intake, or did not improve patient’s self-reported pain and functional recovery compared with standard bupivacaine.

Enhanced recovery programs have been associated with improved outcomes after gynecologic surgery. There are limited data on the effect of enhanced recovery programs on healthcare costs or healthcare service use.The purpose of this study was to evaluate differences in hospital charges for women who undergo surgery for a suspected gynecologic cancer that is managed in an enhanced recovery program as compared with conventional perioperative care.We performed a retrospective cohort study of women who underwent open abdominal surgery for a suspected gynecologic cancer before and after the implementation of an enhanced recovery after surgery program. Consecutive patients from May to October 2014 and from November 2014 to November 2015 comprised the conventional perioperative care (before enhanced recovery after surgery) and enhanced recovery after surgery cohorts, respectively. Patients were excluded if they underwent surgery with a multidisciplinary surgical team or minimally invasive surgery. All technical and professional charges were ascertained for all healthcare services from the day of surgery until postoperative day 30. Charges for adjuvant treatment were excluded. Charges were classified according to the type of clinical service provided. The primary outcome was the difference in total hospital charges between the pre-enhanced recovery after surgery and the enhanced recovery after surgery groups. Secondary outcomes were between group differences in hospital charges within clinical service categories.A total of 271 patients were included in the analysis (58 patients in the pre-enhanced recovery after surgery and 213 patients in the enhanced recovery after surgery cohort). A total of 70,177 technical charges and 6775 professional charges were identified and classified. The median hospital charge for a patient decreased 15.6% in the enhanced recovery after surgery group compared with the pre-enhanced recovery after surgery group (95% confidence interval, 5-24.5%; P=.008). Patients in the enhanced recovery after surgery group also had lower charges for laboratory services (20% lower; 95% confidence interval, 0--39%; P=.04), pharmacy services (30% lower; 95% confidence interval, 14--41%; P.001), room and board (25% lower; 95% confidence interval, 20--47%; P=.005), and material goods (64% lower; 95% confidence interval, 44--81%; P.001). No differences in charges were observed for perioperative services, diagnostic procedures, emergency department care, transfusion-related services, interventional radiology procedures, physical/occupational therapy, outpatient care, or other services.Hospital charges and healthcare service use were lower for enhanced recovery patients compared with patients who received conventional perioperative care after open surgery for a suspected gynecologic cancer. Enhanced recovery programs may be considered to be high value in healthcare because they provide improved outcomes while lowering resource use.

OBJECTIVE: To investigate the effect of an enhanced recovery after surgery (ERAS) program on perioperative outcomes with an emphasis on opioid consumption and patient-reported outcomes in the immediate and extended postoperative period. METHODS: We initiated our ERAS program as part of a quality improvement initiative in November 2014. We compared clinical outcomes among a cohort of 607 women undergoing open gynecologic surgery before or after implementation of ERAS. For 293 patients, patient reported outcomes were compared using the MD Anderson Symptom Inventory-Ovarian Cancer (MDASI-OC). RESULTS: Median age was 58 years (18–85). Median length of stay decreased by 25% for patients in the ERAS pathway, (p

Serous tubal intraepithelial carcinoma is considered the precursor lesion of high-grade serous carcinoma, and found in both low-risk and high-risk populations. Isolated serous tubal intraepithelial carcinomas in patients with BRCA1/2 mutations are detected in ∼2% of patients undergoing risk-reducing bilateral salpingo-oophorectomy and even with removal of the tubes and ovaries the rate of developing primary peritoneal carcinoma following remains up to 7.5%. Postoperative recommendations after finding incidental STICs remain unclear and surgical staging, adjuvant chemotherapy, or observation have been proposed. Discovery of STIC should prompt consideration of hereditary cancer program referral for BRCA1/2 mutation screening.

The analytical algorithm of Lynch syndrome (LS) is increasingly complex. BRAF V600E mutation and MLH1 promoter hypermethylation have been proposed as a screening tool for the identification of LS. The aim of this study was to assess the clinical usefulness and cost-effectiveness of both somatic alterations to improve the yield of the diagnostic algorithm of LS. A total of 122 colorectal tumors from individuals with family history of colorectal cancer that showed microsatellite instability and/or loss of mismatch repair (MMR) protein expression were studied. MMR germline mutations were detected in 57 cases (40 MLH1, 15 MSH2 and 2 MSH6). BRAF V600E mutation was assessed by single-nucleotide primer extension. MLH1 promoter hypermethylation was assessed by methylation-specific multiplex ligation-dependent probe amplification in a subset of 71 cases with loss of MLH1 protein. A decision model was developed to estimate the incremental costs of alternative case-finding methods for detecting MLH1 mutation carriers. One-way sensitivity analysis was performed to assess robustness of estimations. Sensitivity of the absence of BRAF mutations for depiction of LS patients was 96% (23/24) and specificity was 28% (13/47). Specificity of MLH1 promoter hypermethylation for depiction of sporadic tumors was 66% (31/47) and sensitivity of 96% (23/24). The cost per additional mutation detected when using hypermethylation analysis was lower when compared with BRAF study and germinal MLH1 mutation study. Somatic hypermethylation of MLH1 is an accurate and cost-effective pre-screening method in the selection of patients that are candidates for MLH1 germline analysis when LS is suspected and MLH1 protein expression is absent.

The diagnosis and management of four cases of dermatological disorders, most of which are related to the endocrine disorder of androgen excess, are presented. Combined oral contraceptives (COCs) may be useful when well-tolerated hormonal therapy and/or when contraception is required. A female patient with androgenetic alopecia or female pattern balding, without underlying hyperandrogenism, was treated with ethinylestradiol/chlormadinone acetate (EE/CMA) 0.03 mg/2 mg for 6 months and experienced stabilization of hair loss (case report 1). A patient who had previously received a COC for an irregular menstrual pattern but again experienced irregular menses and also acne after stopping treatment was diagnosed with acne associated with polycystic ovary syndrome (PCOS) [case report 2]. After 6 month's treatment with EE/CMA 0.03 mg/2 mg, this patient had fewer acne lesions and became eumenorrheic. A third patient who had excess hair since childhood was diagnosed with idiopathic hirsutism (no underlying gynecological or endocrinological disorder was found) and was treated with EE/CMA 0.03 mg/2 mg (case report 3). Less hair growth was reported after 6 months' treatment. Case report 4 describes a patient who presented with oligomenorrhea and acne. She was diagnosed with PCOS with acne, seborrhea and mild hirsutism. Treatment with EE/CMA 0.03 mg/2 mg for 6 months resulted in improvements in her facial acne, seborrhea and hirsutism; she also became eumenorrheic. These four cases illustrate that EE/CMA may be a useful and well tolerated treatment option in the management of patients with dermatological disorders with or without hyperandrogenization.

Male breast cancer (MBC) is a rare disease in the U.S., accounting for less than 1% of all breast cancers. Rates of MBC in Africa are more variable than in the U.S., therefore, understanding the risk factors involved in a population like Egypt can clarify the nature of MBC. The polyglutamine tract (QT) is a variable region of the androgen receptor (AR), a nuclear receptor which is important in modulating androgen actions and generally inhibits growth in breast tissue. It is hypothesized that a long QT results in weaker AR activity over the lifetime, resulting in less AR mediated control over cellular division and higher risk of MBC. As a corollary, we expect to see a distribution skewed toward longer QTs in MBC patients compared to controls and overall relatively longer QT's in populations with higher rates of MBC. This study aimed to investigate for the first time the distribution of AR QT lengths among MBC patients in Egypt. Paraffin-embedded tumor tissues from 44 Egyptian MBC patients were analyzed for this polymorphism. Amplification followed by fragment length analysis revealed QT length. For the control series, blood from 43 Egyptian males without a family or personal history of breast or prostate cancers was collected and analyzed similarly. There was no significant difference between patients and controls with respect to mean QT length (P = 0.84; means were 19.5 ± 2.8 and 19.3 ± 4.2, for patients and controls, respectively). Though, short QT lengths were more prevalent among controls (14.0%), but almost absent in cases (2.3%). Although the mean lengths were not different in cases and controls, the near absence of short tracts in cases suggests a possible protective effect of very short QT lengths against MBC. In populations in which there is variable incidence of MBC by region, investigations of the distribution of AR QT lengths are warranted to further delineate its role as a risk factor in MBC.

Microsatellite instability (MSI) is displayed by approximately 15% of colorectal cancers (CRC). Defective DNA mismatch repair generates mutations at repetitive DNA sequences such as those located in the double strand break (DSB) repair gene MRE11. We assessed the mutational status of MRE11 in a panel of 17 CRC cell lines and 46 primary tumors and found a strong correlation with MSI status in both cell lines and tumors. Therefore, we hypothesized that deficiency in MRE11 may sensitize CRC cells to poly(ADP-ribose) polymerase (PARP-1) inhibition based on the concept of synthetic lethality. We further assessed the activity of the PARP-1 inhibitor, ABT-888, in CRC cell lines and observed preferential cytotoxicity in those MSI cell lines harboring mutations in MRE11 compared with both wild-type cell lines and microsatellite stable (MSS) cell lines. A significant correlation between MRE11 expression levels and cytotoxicity to ABT-888 at 10 μM was observed (R2 = 0.915, P < 0.001). Using two experimental approaches, including short hairpin RNA knocking down MRE11 in the wild-type and MSS cell line SW-480 and a second cell line model transfected with mutant MRE11, we experimentally tried to confirm the role of MRE11 in conferring sensitivity to PARP-1 inhibition. Both models led to changes in proliferation in response to ABT-888 at different concentrations, and a drug–response effect was not observed, suggesting a possible contribution of additional genes. We conclude that MSI colorectal tumors deficient in DSB repair secondary to mutation in MRE11 show a higher sensitivity to PARP-1 inhibition. Further clinical investigation of PARP-1 inhibitors is warranted in MSI CRCs. Cancer Res; 71(7); 2632–42. ©2011 AACR.

265 Background: A key component of any Enhanced Recovery After Surgery (ERAS) program is standardized multimodal analgesia to minimize opioid use. Our program utilizes acetaminophen, nonsteroidal anti-inflammatory agents and gabapentanoids perioperatively. The primary aim of our study was to evaluate pregabalin use after surgery and impact on total morphine equivalent daily dose (MEDD). Methods: Data was collected retrospectively on consecutive ERAS patients who underwent open gynecologic surgery from 3/4/2016 through 2/22/2018. We excluded any patient identified as a chronic opioid user. Standard preoperative medications included 300 mg tramadol ER, 75 mg pregabalin, and 400 mg celecoxib per institutional guidelines. Standard postoperative pain regimen included scheduled oral acetaminophen, ibuprofen and pregabalin unless contraindicated with rescue oral oxycodone and IV hydromorphone as needed. Pregabalin was ordered 75 mg twice daily for 4 doses. Recommended exceptions to pregabalin included hypersensitivity or age greater than 65 years. Median and range were calculated to summarize continuous variables. Spearman’s rank was used to test the correlation between post-operative pregabalin dose and MEDD. Results: A total of 533 patients were included for analysis. Twelve patients were excluded for chronic opioid use. 38% of patients received all four post-operative pregabalin doses (207/533). 32.8% of patients received no pregabalin (175/533). The fourth dose was the most common missed dose (274/533, 51.4%). The top reasons dose 4 was missed included not being ordered (58.8%) and patient already discharged (12.4%). There were 202 patients older than 65 years, the majority of these patients received no post-operative pregabalin (123/202, 60.9%). There was no difference in the amount of MEDD between those who received all pregabalin doses compared to those who received none (90.75 mg [4-663.5 mg] vs 82.5 mg [4-634.5 mg]; p = 0.269). Conclusions: Pregabalin for preemptive analgesia in an ERAS program does not decrease MEDD.

252 Background: Surgical site infections (SSI) are infections of the surgical incision or organ space within 30 days of surgery and are associated with increased morbidity, mortality and healthcare expenditures. Diabetic patients undergoing laparotomy are at high risk. Prior studies have shown SSI reduction by avoiding hyperglycemia. The aim of our Quality Improvement (QI) initiative is to reduce the SSI rate among diabetic patients undergoing laparotomy by 40% within 2 years compared to the baseline (2/2015-8/2017) rate of 16%. Methods: We formed a multi-disciplinary QI team including physicians, nurses and advanced care providers from Gynecologic Oncology, Pharmacy, Nutrition, Endocrinology, Internal Medicine and Anesthesiology. The intervention began 2/2018 in our main center and 5 satellite sites including: screening gynecologic cancer patients undergoing laparotomy with hemoglobin A1C, intra-operative glucose monitoring with goal of < 180mg/dL, creation and use of a standardized basal-bolus insulin order set for post-operative care, and endocrine and nutritional consultation. The following variables were assessed: age, race, ethnicity, BMI, cancer type, comorbidities, smoking status, surgical procedure, receipt of antibiotic prophylaxis, hemoglobin A1C, post-operative glucose values, intervention compliance, intra-operative complications, post-operative complications including SSI, hospital readmissions, reoperation and mortality. Results: Since 2/2018, 39 gynecologic cancer patients have undergone laparotomy. Overall compliance with HgA1c screening is 64% (25/39), which has improved from 42% in 2/2018 to 70% in 3/2018 and 83% in 4/2018. Causes of non-compliance included unplanned conversion to laparotomy and need for additional education. Five of 39 (13%) patients were diabetic, including one newly diagnosed through this initiative. The post-intervention diabetic SSI rate is 0% (0/5) with all post-intervention glucose values < 180mg/dL. There have been no safety adverse events resulting in patient harm. Conclusions: Implementing a QI initiative to standardize management of diabetic patients undergoing surgery is both safe and feasible. Effectiveness data will continue to be collected.

The CHEK2*1100delC mutation has been reported to confer a twofold increased risk of breast cancer among carriers. The frequency of the mutation varies among populations. The highest frequency has been described in Northern and Eastern European countries; the frequency may be much lower in North America. In this study, our aim was to determine the frequency of CHEK2*1100delC in members of breast cancer families who tested negative for a deleterious mutation in BRCA1/2 at the University of Michigan Comprehensive Cancer Center. We genotyped 102 members from 90 families for CHEK2*1100delC. Most of these families had several cases of breast cancer or ovarian cancer (or both), as well as multiple members with other cancer types in a single lineage. No CHEK2*1100delC mutations were detected in any of the 102 individuals, including 51 women diagnosed with breast cancer at an early age (
