RESUMEN
OBJECTIVE: To determine if tumor genetics are associated with overall survival (OS) after concurrent resection of colorectal liver metastases (CLM) and extrahepatic disease (EHD). SUMMARY BACKGROUND DATA: The prognosis for patients who undergo concurrent resection of CLM/EHD is unclear and the impact of somatic mutations has not been reported. METHODS: Patients undergoing concurrent resection of CLM and EHD from 2007 to 2017 were identified from 2 academic centers. From 1 center, patients were selected from a pre-existing database of patients undergoing cytore-ductive surgery with hyperthermic intraperitoneal chemotherapy. The Kaplan-Meier method was used to construct survival curves, compared using the log-rank test. Multivariable Cox analysis for OS was performed. RESULTS: One hundred nine patients were included. Most common EHD sites included lung (33 patients), peritoneum (32), and portal lymph nodes (14). TP53 mutation was the most common mutation, identified in 75 patients (69%), and RAS/TP53 co-mutation was identified in 31 patients (28%). The median OS was 49 months (interquartile range, 24-125), and 3- and 5-year OS rates were 66% and 44%, respectively. Compared to patients without RAS/ TP53 co-mutation, patients with RAS/TP53 co-mutation had lower median OS: 39 vs. 51 months ( P = 0.02). On multivariable analysis, lung EHD [hazard ratio (HR), 0.7; 95% confidence intervals (CI), 0.3-1.4], peritoneal EHD (HR, 2.2; 95% CI, 1.1-4.2) and RAS/TP53 co-mutation (HR, 2.8; 95% CI, 1.1-7.2) were independently associated with OS. CONCLUSIONS: RAS/TP53 co-mutation is associated with worse OS after concurrent CLM/EHD resection. Mutational status and site of EHD should be included in the evaluation of patients considered for concurrent resection.

BACKGROUND: We measured the importance patients with gastrointestinal cancer and health care providers place on treatment outcomes, quality of life, and costs. METHODS: This cross-sectional survey study was conducted between June 1, 2020 and November 30, 2020. We identified surviving patients who had been treated or were anticipating treatment for pancreatic or gastric cancer at our single institution from January 1, 2000 through January 31, 2020. Surveys assessed the importance patients and providers placed on outcomes, well-being, costs, and experiences. Surveys measured how these values had changed over time. We compared the importance patients and providers place on each of the attributes of value. RESULTS: A total of 383 patients and 164 providers responded. Providers felt experience, emotional well-being, and costs were more important than patients themselves did (all p < 0.05). Patients more commonly reported that survival had become more important to them over time, while providers believed that emotional well-being, experience, and costs had become more important to patients (all p < 0.05). Postoperative patients ranked functional well-being as more important than preoperative patients did (p = 0.031). Patients of lower income and education levels more reported concerns of costs over the course of their care (both p < 0.05). Younger age was associated with concern for direct (r = -0.167, p = 0.004) and indirect costs (r = -0.318, p < 0.001). CONCLUSIONS: Although there are consistencies amongst the views of cancer patients and providers, there remain discordances in the perception of value. Patients' values differed across their treatment and survivorship course. These data demonstrate the importance of accounting for multistakeholder perspectives in assessments of value in health care.

BACKGROUND: While surgery is a mainstay of curative-intent treatment for patients with intrahepatic cholangiocarcinoma (IHC), the role of neoadjuvant therapy (NT) has not been well-established. We sought to describe trends in NT utilization, characterize associated factors, and evaluate association with overall survival (OS). METHODS: Retrospective cohort study of 4456 surgically resected IHC patients within National Cancer Data Base (2006-2016). NT included chemotherapy alone and/or (chemo)radiation. Descriptive statistics used to describe the cohort. Multivariable hierarchical logistic regression models were used to examine factors associated with NT administration. Analyses conducted comparing OS among upfront surgery patients and NT patients using propensity matching using nearest-neighbor methodology and adjustment using inverse probability of treatment weighting (IPTW). Association between NT and risk of death evaluated using multivariable Cox shared frailty modeling. RESULTS: Utilization of NT did not significantly increase over time (11%-2006 to 16%-2016, trend test p = 0.07) but did increase among patients with clinical nodal involvement (cN+, 13% to 36%, p = 0.002). Factors associated with NT use include cN+ disease (odds ratio [OR] 1.68, 95% confidence interval [CI] 1.31-2.15) and advanced clinical T stage: T2 (OR 1.65, 95% CI 1.33-2.06); T3 (OR 1.51, 95% CI 1.13-2.02). After propensity matching, NT associated with a 23% decreased risk of death relative to upfront surgery (hazard ratio [HR] 0.77, 95% CI 0.61-0.97). Findings were similar after IPTW (HR 0.83, 95% CI 0.78-0.88). CONCLUSIONS: NT is increasingly used for the management of IHC patients with characteristics indicating aggressive tumor biology and is associated with decreased risk of death. These data suggest need for prospective studies of NT in management of patients with potentially resectable IHC.

The application of minimally invasive surgery (MIS) techniques in the treatment of hepatobiliary malignancies offers advantages of shorter length of stay, quicker functional recovery, and decreased need for postoperative opioids. However, MIS completion radical cholecystectomy for incidentally diagnosed gallbladder cancer can be challenging due to a reoperative field and lack of tactile feedback. This video demonstrates the utility of the robotic platform and highlights the ways in which it assists surgeons in overcoming these limitations. These include (1) versatile wristed instruments and excellent visualization that facilitate a thorough regional lymphadenectomy; and (2) built-in fluorescence imaging technology that can be used with intravenous indocyanine green (ICG) to confirm porta hepatis anatomy in a reoperative field. ICG pharmacokinetics enable fluorescence angiography 15-20 s after ICG injection and fluorescence cholangiography 15-20 min after ICG injection as the dye accumulates in the biliary system. Systematic and intentional application of these techniques allows for the safe performance of robotic completion radical cholecystectomy following sound oncologic principles, with excellent perioperative outcomes.

BACKGROUND: Two-stage hepatectomy (TSH) is an important tool in the management of bilateral colorectal liver metastases (CRLM). This study sought to examine the presentation, management, and outcomes of patients completing TSH in major hepatobiliary centers in the United States (US). METHODS: A retrospective review from five liver centers in the US identified patients who completed a TSH procedure for bilateral CRLM. RESULTS: From December 2000 to March 2016, a total of 196 patients were identified. The majority of procedures were performed using an open technique (n = 194, 99.5%). The median number of tumors was 7 (range 2-33). One-hundred and twenty-eight (65.3%) patients underwent portal vein embolization. More patients received chemotherapy prior to the first stage than chemotherapy administration preceding the second stage (92% vs. 60%, p = 0.308). Median overall survival (OS) was 50 months, with a median follow-up of 28 months (range 2-143). Hepatic artery infusion chemotherapy was administered to 64 (32.7%) patients with similar OS as those managed without an infusion pump (p = 0.848). Postoperative morbidity following the second-stage resection was 47.4%. Chemotherapy prior to the second stage did not demonstrate an increased complication rate (p = 0.202). Readmission following the second stage was 10.3% and was associated with a decrease in disease-free survival (p = 0.003). OS was significantly decreased by positive resection margins and increased estimated blood loss (EBL; p = 0.036 and p = 0.05, respectively). CONCLUSION: This is the largest TSH series in the US and demonstrates evidence of safety and feasibility in the management of bilateral CRLM. Outcomes are influenced by margin status and operative EBL.

BACKGROUND: There remains no tool to quantify the total value of comparative processes in health care. Hospital administrative data sets are emerging as valuable sources to evaluate performance. Thus, we use a framework to simultaneously assess multiple domains of value associated with an enhanced recovery initiative using national administrative data. MATERIALS AND METHODS: Risk-stratified clinical pathways for patients undergoing pancreatic surgery were implemented in 2016 at our institution. We used a national administrative database to characterize changes in value associated with this initiative. Value metrics assessed included in-hospital mortality, complication rates, length of stay (LOS), 30-day readmission rates, and institutional costs. We compared our performance with other hospitals both before and after implementation of the pathways. Metrics were graphed on radar charts to assess overall value. RESULTS: 22,660 cases were assessed. Comparing 75 cases at our institution and 5520 cases at all other hospitals before pathway implementation, mean in-hospital LOS was 9.6 versus 10.8 d, in-hospital mortality was 0.0% versus 1.9%, mean costs were $23,585 versus $21,387, 30-day readmission rates were 1.3% versus 7.4%, and complication rates were 8.0% versus 11.2%, respectively. Comparing 334 cases at our institution and 16,731 cases at all other hospitals after pathway implementation, mean in-hospital LOS was 7.7 versus 10.3 d, in-hospital mortality was 0.3% versus 1.6%, mean costs were $19,428 versus $22,032, 30-day readmission rates were 6.6% versus 7.5%, and complication rates were 6.3% versus 10.3%, respectively. Notably, LOS and institutional costs were reduced at our institution after implementation of the enhanced clinical care pathways. Our costs were higher than comparators before implementation, but lower than comparators after implementation. CONCLUSIONS: Herein, we used an analytic framework and used national administrative data to assess the value of an enhanced care initiative as benchmarked with data from other hospitals. We thus illustrate how to identify and measure opportunities for targeted improvements in health care delivery. We also recognize the limitations of the use of administrative data in a comprehensive assessment of value in health care.

BACKGROUND: An opioid reduction education program to decrease discharge opioid prescriptions was initiated in our Department of Surgical Oncology. The study's aim was to measure the results and sustainability of these interventions 1 year later. METHODS: This prospective quality improvement project identified patients undergoing resection in five index tumor sites (peritoneal surface, sarcoma, stomach, pancreas, liver) at a high-volume cancer center. Patients were grouped into pre-education (PRE: July 2017-July 2018) and posteducation (POST: September 2018-July 2019) periods, before and after departmental education talks and videos in August 2018. Opioids were converted to oral morphine equivalents (OME) to compare the groups. RESULTS: Of 1168 evaluable patients (PRE 646, 55%; POST 522, 45%), the median last-24-h inpatient OME was 15 mg in PRE patients and 10 mg in POST patients (p < .001). Median discharge OME decreased from 200 mg in PRE to 100 mg in POST patients (p < .001). The frequency of patients with zero discharge opioids increased from 11% to 19% (p < .001). This discharge OME reduction amounted to 52,200 mg OME saved, or the equivalent of 6960 5-mg oxycodone pills not disseminated. CONCLUSIONS: A perioperative opioid reduction education program targeted to providers halved discharge OME, with sustained reductions 1 year later.

OBJECTIVE: The aim of the study was to determine the prognostic impact of co-existence of APC and PIK3CA mutations in patients undergoing preoperative chemotherapy and resection for colorectal liver metastases (CLM). BACKGROUND: Co-occurring genetic events have been shown to drive carcinogenesis in multiple malignancies. METHODS: We identified 396 patients with primary colorectal cancer and known somatic mutation status by next-generation sequencing who underwent hepatectomy for CLM (2005-2015). Survival after hepatectomy in patients with double mutation of APC and PIK3CA and others was analyzed. Predictors of pathologic response and survival were determined. The prognostic value of double mutation was evaluated with a separate cohort of 157 patients with CLM undergoing chemotherapy alone. RESULTS: Forty-five patients had double mutation of APC and PIK3CA; 351 did not. Recurrence-free survival (RFS) and overall survival (OS) after hepatectomy were worse in patients with double mutation (3-year RFS, 3.1% vs 20% [P < 0.001]; 3-year OS, 44% vs 84% [P < 0.001]). Independent predictors of major pathologic response were bevacizumab use (odds ratio [OR] 2.22; P = 0.001), tumor size <3âcm (OR 1.97; P = 0.004), wild-type RAS (OR 2.00; P = 0.003), and absence of double mutation (OR 2.91; P = 0.002). Independent predictors of worse OS were primary advanced T category (hazard ratio [HR] 2.12; P = 0.021), RAS mutation (HR 1.74; P = 0.015), and double mutation (HR 3.09; P < 0.001). In the different medical cohort, patients with double mutation had worse 3-year OS of 18%, compared with 35% without double mutation (P = 0.023). CONCLUSIONS: Double mutation of APC and PIK3CA predicts inferior response to preoperative chemotherapy and poor survival in patients with CLM.

OBJECTIVE: The aim of this study was to evaluate trends over time in perioperative outcomes for patients undergoing hepatectomy. BACKGROUND: As perioperative care and surgical technique for hepatectomy have improved, the indications for and complexity of liver resections have evolved. However, the resulting effect on the short-term outcomes over time has not been well described. METHODS: Consecutive patients undergoing hepatectomy during 1998 to 2015 at 1 institution were analyzed. Perioperative outcomes, including the comprehensive complication index (CCI), were compared between patients who underwent hepatectomy in the eras 1998 to 2003, 2004 to 2009, and 2010 to 2015. RESULTS: The study included 3707 hepatic resections. The number of hepatectomies increased in each era (794 in 1998 to 2003, 1402 in 2004 to 2009, and 1511 in 2010 to 2015). Technical complexity increased over time as evidenced by increases in the rates of major hepatectomy (20%, 23%, 30%, P < 0.0001), 2-stage hepatectomy (0%, 3%, 4%, P < 0.001), need for portal vein embolization (5%, 9%, 9%, P = 0.001), preoperative chemotherapy for colorectal liver metastases (70%, 82%, 89%, P < 0.001) and median operative time (180, 175, 225âminutes, P < 0.001). Significant decreases over time were observed in median blood loss (300, 250, 200âmL, P < 0.001), transfusion rate (19%, 15%, 5%, P < 0.001), median length of hospitalization (7, 7, 6 days, P < 0.001), rates of CCI ≥26.2 (20%, 22%, 16%, P < 0.001) and 90-day mortality (3.1%, 2.6%, 1.3%, P < 0.01). On multivariable analysis, hepatectomy in the most recent era 2010 to 2015 was associated with a lower incidence of CCI ≥26.2 (odds ratio 0.7, 95% confidence interval 0.6-0.8, P < 0.0001). CONCLUSION: Despite increases in complexity over an 18-year period, continued improvements in surgical technique and perioperative outcomes yielded a resultant decrease in CCI in the most current era.

OBJECTIVE: To characterize opioid discharge prescriptions for pancreatectomy patients. BACKGROUND: Wide variation in and over-prescription of opioids after surgery contribute to the United States opioid epidemic through persistent use past the postoperative period. Objective strategies guiding discharge opioid prescriptions for oncologic surgery are lacking, and factors driving prescription amount are not fully delineated. METHODS: Characteristics of pancreatectomy patients (March 2016-August 2017) were retrospectively abstracted from a prospective database. Discharge opioids prescriptions were converted to oral morphine equivalents (OME). Regression models identified variables associated with discharge OME. RESULTS: In 158 consecutive patients, median discharge OME was 250âmg (range 0-3950). Discharge OME was labeled "low" (<200âmg) for 33 patients (21%) and "high" (>400âmg) for 38 (24%). Only shorter operative time (odds ratio [OR]-0.14, P = 0.004) and inpatient team (OR-15.39, P < 0.001) were independently associated with low discharge OME. Older age was the only variable associated with high discharge OME. Fifty-seven patients (36%) used zero opioids in the last 24-hours predischarge, yet 52 of 57 (91%) still received discharge opioids. Older age (OR-1.07), grade B/C pancreatic fistula (OR-3.84), and epidural use (OR-3.12) were independently associated with zero last-24-hours OME (all P ≤ 0.040). CONCLUSIONS: The wide variation in discharge opioid prescriptions is heavily influenced by provider routine/bias and not by objective criteria such as last-24-hours OME. Quality improvement strategies could include aggressive weaning protocols to increase the proportion of patients with zero/near-zero last-24-hour OME and limiting prescriptions to a conservative multiplier of the last-24-hour OME.

OBJECTIVE: To summarize the multi-specialty strategy and initial guidelines of a Case Review Committee in triaging oncologic surgery procedures in a large Comprehensive Cancer Center and to outline current steps moving forward after the initial wave. SUMMARY OF BACKGROUND DATA: The impetus for strategic rescheduling of operations is multifactorial and includes our societal responsibility to minimize COVID-19 exposure risk and propagation among patients, the healthcare workforce, and our community at large. Strategic rescheduling is also driven by the need to preserve limited resources. As many states have already or are considering to re-open and relax stay-at-home orders, there remains a continued need for careful surgical scheduling because we must face the reality that we will need to co-exist with COVID-19 for months, if not years. METHODS: The quality officers, chairs, and leadership of the 9 surgical departments in our Division of Surgery provide specialty-specific approaches to appropriately triage patients. RESULTS: We present the strategic approach for surgical rescheduling during and immediately after the COVID-19 first wave for the 9 departments in the Division of Surgery at The University of Texas MD Anderson Cancer Center in Houston, Texas. CONCLUSIONS: Cancer surgeons should continue to use their oncologic knowledge to determine the window of opportunity for each surgical procedure, based on tumor biology, preoperative treatment sequencing, and response to systemic therapy, to safely guide patients through this cautious recovery phase.

OBJECTIVE: To test the degree of agreement in selecting therapeutic options for patients suffering from colorectal liver metastasis (CRLM) among surgical experts around the globe. SUMMARY/BACKGROUND: Only few areas in medicine have seen so many novel therapeutic options over the past decades as for liver tumors. Significant variations may therefore exist regarding the choices of treatment, even among experts, which may confuse both the medical community and patients. METHODS: Ten cases of CRLM with different levels of complexity were presented to 43 expert liver surgeons from 23 countries and 4 continents. Experts were defined as experienced surgeons with academic contributions to the field of liver tumors. Experts provided information on their medical education and current practice in liver surgery and transplantation. Using an online platform, they chose their strategy in treating each case from defined multiple choices with added comments. Inter-rater agreement among experts and cases was calculated using free-marginal multirater kappa methodology. A similar, but adjusted survey was presented to 60 general surgeons from Asia, Europe, and North America to test their attitude in treating or referring complex patients to expert centers. RESULTS: Thirty-eight (88%) experts completed the evaluation. Most of them are in leading positions (92%) with a median clinical experience of 25 years. Agreement on therapeutic strategies among them was none to minimal in more than half of the cases with kappa varying from 0.00 to 0.39. Many general surgeons may not refer the complex cases to expert centers, including in Europe, where they also engage in complex liver surgeries. CONCLUSIONS: Considerable inconsistencies of decision-making exist among expert surgeons when choosing a therapeutic strategy for CRLM. This might confuse both patients and referring physicians and indicate that an international high-level consensus statements and widely accepted guidelines are needed.

BACKGROUND: Liver reserve affects survival in hepatocellular carcinoma (HCC). Model for End-Stage Liver Disease (MELD) score is used to predict overall survival (OS) and to prioritize HCC patients on the transplantation waiting list, but more accurate models are needed. We hypothesized that integrating insulin-like growth factor 1 (IGF-1) levels into MELD score (MELD-IGF-1) improves OS prediction as compared to MELD. METHODS: We measured plasma IGF-1 levels in training (n = 310) and validation (n = 155) HCC cohorts and created MELD-IGF-1 score. Cox models were used to determine the association of MELD and MELD-IGF-1 with OS. Harrell's c-index was used to compare the predictive capacity. RESULTS: IGF-1 was significantly associated with OS in both cohorts. Patients with an IGF-1 level of ≤26 ng/mL in the training cohort and in the validation cohorts had significantly higher hazard ratios than patients with the same MELD but IGF-1 >26 ng/mL. In both cohorts, MELD-IGF-1 scores had higher c-indices (0.60 and 0.66) than MELD scores (0.58 and 0.60) (p < 0.001 in both cohorts). Overall, 26% of training and 52.9% of validation cohort patients were reclassified into different risk groups by MELD-IGF-1 (p < 0.001). CONCLUSIONS: After independent validation, the MELD-IGF-1 could be used to risk-stratify patients in clinical trials and for priority assignment for patients on liver transplantation waiting list.

BACKGROUND: The optimal surveillance strategy after resection of colorectal liver metastases (CLM) is unknown. We evaluated changes in recurrence risk after CLM resection and developed a surveillance algorithm. METHODS: Patients undergoing CLM resection during 1998 to 2015 were identified from a prospectively compiled database and analyzed if they had the potential for follow-up longer than the longest observed time to recurrence in this cohort. Changes in recurrence risk and risk factors for recurrence were evaluated. All statistical tests were 2-sided. RESULTS: Among 2,105 patients who were initially identified and underwent CLM resection, the latest recurrence was observed at 87 months; 1,221 consecutive patients from 1998 through 2011 with the potential for at least 87 months of follow-up were included. The risk of recurrence was highest at 0 to 2 years after CLM resection, lower at 2 to 4 years after CLM resection, and steadily lower after 4 years after CLM resection. Factors associated with increased recurrence risk at the time of surgery were primary lymph node metastasis (hazard ratio [HR], 1.54; 95% CI, 1.21-1.97; P<.001), multiple CLM (HR, 1.31; 95% CI, 1.06-1.63; P=.015), largest liver metastasis diameter >5 cm (HR, 1.64; 95% CI, 1.23-2.19; P<.001), and RAS mutation (HR, 1.29; 95% CI, 1.04-1.59; P=.020). In patients without recurrence at 2 years, the only factor still associated with increased recurrence risk was RAS mutation. In those patients, the recurrence rate at 4 years was 59.3% in patients with RAS mutation versus 27.8% in patients with RAS wild-type (P=.019). CONCLUSIONS: For patients who have undergone CLM resection, we propose surveillance every 3 to 4 months during years 0 to 2, every 3 to 4 months (if mutant RAS) versus every 4 to 6 months (if RAS wild-type) during years 2 to 4, and every 6 to 12 months if recurrence-free at 4 years.

BACKGROUND: The objective of this study was to assess current perceptions surrounding opioid prescribing in surgical oncology to inform perioperative quality improvement initiatives. METHODS: After the Society of Surgical Oncology (SSO) approval, a survey was distributed to its membership. Five sample procedures were used to assess provider perceptions and prescribing habits. Data were summarized and compared by self-reported demographics. RESULTS: One hundred and seventy-five participants completed the survey: 149 (85%) faculty, 24 (14%) trainees, and 2 (1%) advanced practice providers. Most participants (76%) practiced in academic programs and 21% practiced in non-US locations. Few differences were identified based on clinical role, academic rank, or practice years. Compared with non-US providers, US providers expected higher pain scores at discharge, recommended greater opioid prescriptions, and estimated more days of opioid use for almost every procedure. More non-US providers believed discharge opioids should not be distributed to patients who are opioid-free in their last 24 inpatient hours (80% vs 50%, P = .001). All providers ranked education as "very important" for reducing opioid prescriptions. CONCLUSIONS: Compared with their international counterparts, US surgical oncology providers expected greater opioid needs and recommended higher prescription numbers. Educating providers on multimodal opioid-sparing bundles, accelerated weaning protocols, and standardized discharge prescribing habits could have a positive impact the US opioid epidemic.

BACKGROUND AND OBJECTIVES: A department-wide opioid reduction education program resulted in a 1-month change in perceptions of opioid needs and prescribing recommendations for surgical oncology patients. This study's aim was to re-evaluate if early trends were retained 1 year later. METHODS: Surgical Oncology attendings, fellows, and advanced practice providers at a Comprehensive Cancer Center were surveyed 1-year after an August 2018 opioid reduction education program, to compare departmental and individual opioid prescribing habits. RESULTS: The September 2019 response rate was 54/93 (58%), with 41 completing both the post-education and 1-year follow-up surveys. The departmental and matched cohort continued to recommend a lower quantity of discharge opioids for all five index operations (by >50%) and expected less postoperative days to zero opioid needs, when compared to pre-education perceptions. Providers continued to agree that discharge opioid prescriptions should be based on a patient's last 24 hours of inpatient opioid use. There was universal agreement that each respondent's opioid administration had decreased in the past year. CONCLUSIONS: The initial 1-month improvements in perioperative opioid prescribing perceptions were retained 1 year later by Surgical Oncology providers who recommended fewer discharge opioids, faster weaning to zero opioids, and standardized patient-specific discharge opioid volume calculations.

INTRODUCTION: The purpose of this study was to compare operative times, surgical outcomes, resource utilization, and hospital charges before and after the implementation of a sentinel lymph node (SLN) mapping algorithm in endometrial cancer. METHODS: All patients with clinical stage I endometrial cancer were identified pre- (2012) and post- (2017) implementation of the SLN algorithm. Clinical data were summarized and compared between groups. Total hospital charges incurred on the day of surgery were extracted from the hospital financial system for each patient and all charges were adjusted to 2017 US dollars. RESULTS: A total of 203 patients were included: 71 patients in 2012 and 130 patients in 2017. There was no difference in median age, body mass index, or stage. In 2012, 35/71 patients (49.3%) underwent a lymphadenectomy. In 2017, SLN mapping was attempted in 120/130 patients (92.3%) and at least one SLN was identified in 110/120 (91.7%). Median estimated blood loss was similar between groups (100 mL vs 75 mL, p=0.081). There was a significant decrease in both median operative time (210 vs 171 min, p=0.007) and utilization of intraoperative frozen section (63.4% vs 14.6%, p<0.0001). No significant differences were noted in intraoperative (p=1.00) or 30 day postoperative complication rates (p=0.30). The median total hospital charges decreased by 2.73% in 2017 as compared with 2012 (p=0.96). DISCUSSION: Implementation of an SLN mapping algorithm for high- and low-risk endometrial cancer resulted in a decrease in both operative time and intraoperative frozen section utilization with no change in surgical morbidity. While hospital charges did not significantly change, further studies are warranted to assess the true cost of SLN mapping.

BACKGROUND: Hepatocellular carcinoma (HCC) de-differentiation is thought to correlate with size, therefore well-differentiated HCC ≥3 cm are considered rare and not fully understood. METHODS: Patients who underwent hepatectomy for HCC between 1998-2016 were retrospectively analyzed. Patient's characteristics and recurrence-free (RFS) and overall (OS) survival were compared between those with atypical- (well-differentiated-HCC ≥3 cm) and typical-HCC (moderate-to-poorly-differentiated HCC ≥3 cm). RESULTS: Of 176 patients included in this study, 37 (21%) had atypical-HCC. Patients with atypical-HCC were less likely to be Asian ethnicity (3% vs. 17%, p = 0.062), have lower rate of viral infection (14% vs. 43%, p = 0.003), cirrhosis (8% vs. 27%, p = 0.015). The tumors were less likely to demonstrate vascular invasion (30% vs. 59%, p = 0.002), and were associated with a lower alpha-fetoprotein level (3.5 ng/ml vs. 33.2 ng/ml, p < 0.001). Patients with atypical-HCC had a longer RFS (5-y RFS: 58.3% vs. 35.7%, p = 0.016) and OS (5-y OS: 79.1% vs 53.3%, p = 0.029) as compared to those with typical-HCC following univariate analysis, however this did not appear following multivariate analysis. CONCLUSION: Patients with atypical-HCC have different characteristic in terms of epidemiology, etiology, cirrhosis and vascular invasion as compared to typical-HCC. The etiology of atypical-HCC may be non-alcoholic fatty liver disease-related and/or malignant transformation of hepatocellular adenoma.

BACKGROUND: The identification of extrauterine disease is critical to the management of patients with high-risk endometrial cancer. The purpose of the current study was to determine the accuracy of preoperative positron emission tomography (PET)/computed tomography (CT) in the detection of extrauterine disease. METHODS: Women with high-risk endometrial cancer were enrolled prospectively and underwent preoperative PET/CT followed by surgery, including sentinel lymph node biopsy and lymphadenectomy. Primary tumor factors on PET/CT were correlated with lymph node pathology. The sensitivity, specificity, positive predictive value, and negative predictive value were calculated for the detection of lymphadenopathy and peritoneal disease by PET/CT. RESULTS: A total of 112 patients were enrolled and underwent PET/CT between April 2013 and May 2016, 108 of whom were evaluable. On PET/CT, 21 patients (19.4%) were found to have extrauterine disease, 18 (17%) had positive lymph nodes, and 8 (7%) had peritoneal disease. A total of 108 patients underwent surgery, 103 of whom (95%) underwent lymphadenectomy. The sensitivity of PET/CT to detect positive lymph nodes was 45.8%, with a specificity of 91.1%, positive predictive value of 61.1%, and negative predictive value of 84.7%. The false-negative rate was 54.2%. There was no difference in primary tumor characteristics on imaging noted between patients with positive and negative lymph nodes. The sensitivity of PET/CT to detect peritoneal disease was 37.5%, with a specificity of 97.8%, positive predictive value of 75%, and negative predictive value of 90.0%. The false-negative rate was 62.5%. CONCLUSIONS: Preoperative PET/CT did not reliably predict the presence of extrauterine disease in women with high-risk endometrial cancer. Given the high false-negative rates, PET/CT should not be used in the preoperative treatment planning of these patients.

OBJECTIVE: To review efficiency metrics and patient safety data before and after implementation of a structured review process for surgical innovations. SUMMARY BACKGROUND DATA: Surgical innovation ranges from minor incremental improvement to radical experimentation. Although innovation paradigms have been described, these are not widely adopted or enforced in the surgical community. METHODS: A Continuous Quality Improvement Team (CQIT) of surgical quality officers and perioperative nurses was organized to perform structured reviews of proposed new surgical devices and procedures at a large quaternary cancer care center. The CQIT process was placed to precede an established Value Analysis Team business evaluation. Pre- and post-CQIT implementation metrics of approval process efficiency and patient safety data were compared. Seven novel procedures were also vetted by the CQIT. RESULTS: Forty-six product requests were evaluated after CQIT implementation. Compared with 34 products evaluated prior to CQIT establishment, the total mean evaluation time decreased from 124 to 51 days (P= 0.007). For new devices requiring intraoperative trial, the time between product proposal and trial decreased from a mean of 260 to 99 days (P= 0.014). The rate of device-related complications in the pre-CQIT group was 10% compared with 0% post-CQIT. Two devices, which administratively bypassed CQIT review, had both minor and major complications, including a mortality. Five novel procedures approved by CQIT with simulation were performed without complications. CONCLUSIONS: Using novel algorithms, the addition of a dedicated team of surgical quality officers to the surgical innovation evaluation process improved both the efficiency and the safety associated with introducing new devices and procedures into practice.
