Abstract
Sigma-2-ligands (S2L) are characterized by high binding affinities to their cognate sigma-2 receptor, overexpressed in rapidly proliferating tumor cells. As such, S2L were developed as imaging probes (ISO1) or as cancer therapeutics, alone (SV119 [C6], SW43 [C10]) and as delivery vehicles for cytotoxic drug cargoes (C6-Erastin, C10-SMAC). However, the exact mechanism of S2L-induced cytotoxicity remains to be fully elucidated. A series of high-affinity S2L were evaluated regarding their cytotoxicity profiles across cancer cell lines. While C6 and C10 displayed distinct cytotoxicities, C0 and ISO1 were essentially non-toxic. Confocal microscopy and lipidomics analysis in cellular and mouse models revealed that C10 induced increases in intralysosomal free cholesterol and in cholesterol esters, suggestive of unaltered intracellular cholesterol trafficking. Cytotoxicity was caused by cholesterol excess, a phenomenon that contrasts the effects of NPC1 inhibition. RNA-sequencing revealed gene clusters involved in cholesterol homeostasis and ER stress response exclusively by cytotoxic S2L. ER stress markers were confirmed by qPCR and their targeted modulation inhibited or enhanced cytotoxicity of C10 in a predicted manner. Moreover, C10 increased sterol regulatory element-binding protein 2 (SREBP2) and low-density lipoprotein receptor (LDLR), both found to be pro-survival factors activated by ER stress. Furthermore, inhibition of downstream processes of the adaptive response to S2L with simvastatin resulted in synergistic treatment outcomes in combination with C10. Of note, the S2L conjugates retained the ER stress response of the parental ligands, indicative of cholesterol homeostasis being involved in the overall cytotoxicity of the drug conjugates. Based on these findings, we conclude that S2L-mediated cell death is due to free cholesterol accumulation that leads to ER stress. Consequently, the cytotoxic profiles of S2L drug conjugates are proposed to be enhanced via concurrent ER stress inducers or simvastatin, strategies that could be instrumental on the path toward tumor eradication.

Abstract
BACKGROUND We sought to derive and validate a prediction model of survival and recurrence among Western patients undergoing resection of gastric cancer. METHODS Patients who underwent curative-intent surgery for gastric cancer at seven US institutions and a major Italian center from 2000 to 2020 were included. Variables included in the multivariable Cox models were identified using an automated model selection procedure based on an algorithm. Best models were selected using the Bayesian information criterion (BIC). The performance of the models was internally cross-validated via the bootstrap resampling procedure. Discrimination was evaluated using the Harrell's Concordance Index and accuracy was evaluated using calibration plots. Nomograms were made available as online tools. RESULTS Overall, 895 patients met inclusion criteria. Age (hazard ratio [HR] 1.47, 95% confidence interval [CI] 1.17-1.84), presence of preoperative comorbidities (HR 1.66, 95% CI 1.14-2.41), lymph node ratio (LNR; HR 1.72, 95% CI 1.42-2.01), and lymphovascular invasion (HR 1.81, 95% CI 1.33-2.45) were associated with overall survival (OS; all p < 0.01), whereas tumor location (HR 1.93, 95% CI 1.23-3.02), T category (Tis-T1 vs. T3: HR 0.31, 95% CI 0.14-0.66), LNR (HR 1.82, 95% CI 1.45-2.28), and lymphovascular invasion (HR 1.49; 95% CI 1.01-2.22) were associated with disease-free survival (DFS; all p < 0.05) The models demonstrated good discrimination on internal validation relative to OS (C-index 0.70) and DFS (C-index 0.74). CONCLUSIONS A web-based nomograms to predict OS and DFS among gastric cancer patients following resection demonstrated good accuracy and discrimination and good performance on internal validation.

Abstract
Thunderbeat™ is a device that uses both ultrasonic and advanced bipolar energies to achieve hemostasis. It has been evaluated in a variety of clinical contexts, but no literature exists regarding its application to pancreatic surgery. Using a prospective, randomized controlled trial, we evaluated its safety and efficacy in the Whipple procedure. Thirty-two participants were enrolled in the study. The Thunderbeat™ device during the Whipple procedure showed similar safety profile compared to standard of care.

Abstract
BACKGROUND Adrenocortical carcinoma is a rare, aggressive cancer. We compared features of patients who underwent synchronous versus metachronous metastasectomy. METHODS Adult patients who underwent resection for metastatic adrenocortical carcinoma from 1993 to 2014 at 13 institutions of the US adrenocortical carcinoma group were analyzed retrospectively. Patients were categorized as synchronous if they underwent metastasectomy at the index adrenalectomy or metachronous if they underwent resection after recurrence of the disease. Factors associated with overall survival were assessed by univariate analysis. RESULTS In the study, 84 patients with adrenocortical carcinoma underwent metastasectomy; 26 (31%) were synchronous and 58 (69%) were metachronous. Demographics were similar between groups. The synchronous group had more T4 tumors at the index resection (42 vs 3%, P < .001). The metachronous group had prolonged median survival after the index resection (86.3 vs 17.3 months, P < .001) and metastasectomy (36.9 vs 17.3 months, P = .007). Synchronous patients with R0 resections had improved survival compared to patients with R1/2 resections (P = .008). Margin status at metachronous metastasectomy was not associated with survival (P = .452). CONCLUSION Select patients with metastatic adrenocortical carcinoma may benefit from metastasectomy. Patients with metachronous metastasectomy have a more durable survival benefit than those undergoing synchronous metastasectomy. This study highlights need for future studies examining differences in tumor biology that could explain outcome disparities in these distinct patient populations.

Abstract
BACKGROUND Staging laparoscopy (SL) is used to avoid resection failure and thus increase the curative resection rate. SL utilization in extra-hepatic biliary tumors (EHBT) is variable. METHODS Data from 1090 patients with potentially resectable EHBT including gallbladder (GBC), distal (DC), and hilar (HC) subtypes were retrospectively collected from 10 academic centers (2000-2015). RESULTS The SL utilization rate increased over time and was significantly higher in GBC than DC and HC. SL yield was 16.8% and did not differ between groups or over time. In patients undergoing attempted resection with prior SL, the curative resection rate did not differ between subtypes. In patients undergoing attempted resection without prior SL, the curative resection rate was less in GBC compared with DC or HC. After matching cohorts by inverse probability weighting, prior SL was associated with curative resection in GBC only (odds ratio [OR], 2.41, 95% CI, 1.36-4.27). On multivariable regression analysis, elevated carbohydrate antigen 19-9 (CA 19-9), low serum albumin, and GBC were strong predictors of distant disease on SL. After categorizing patients undergoing SL into low, intermediate, and high-risk groups based on these parameters, SL yield improved progressively from 10.0% to 19.6% to 52.6%. CONCLUSIONS We recommend routine SL for patients with GBC, particularly with elevated CA19-9 level and/or decreased serum albumin.

Abstract
Abstract
Introduction: The sigma 2 receptor is overexpressed in pancreatic cancer and has been an attractive target for development of cancer selective therapies. However, the mechanism of sigma 2 mediated cancer cell death remains elusive. The sigma 2 receptor has been recently identified as TMEM97, a lysosomal/endoplasmic reticulum protein involved in regulation of cholesterol export in conjunction with NPC1.
Methods: Uptake of SW43 in pancreatic cancer cells was visualized using a NBD fluorophore conjugated ligand. Intracellular cholesterol staining was visualized using filipin staining. Protein expression was quantified by both Western blot and RT qPCR. Cell death was assayed in triplicate using Titer-Glo viability assay.
Results: We hypothesized that sigma 2 ligands may kill pancreatic cancer cells through disruption of lysosomal cholesterol export. Using ASPC1 pancreatic cancer cells, we first demonstrate that sigma 2 ligand SW43 is rapidly taken up and targets to endo-lysosomal compartments, and that treatment with SW43 causes a rapid and dose dependent sequestration of cholesterol in lysosomal compartments as visualized by filipin cholesterol staining. This correlated to an increase in TMEM97 and corresponding decrease in NPC1 expression following SW43 treatment. We next demonstrate that this cholesterol sequestration phenotype is required for cell death, and might be related to the free amine side chain of SW43, as its N-phthalimide derivative fails to induce both lysosomal cholesterol sequestration and cell death despite high doses of ligand used. Lysosomal cholesterol sequestration from sigma 2 ligand treatment sensitizes cells to further targeting of cholesterol metabolism. Using low doses of simvastatin and SW43, we demonstrate that targeting both cholesterol export and cholesterol synthesis displays significant synergism in killing ASPC1 pancreatic cancer cells.
Conclusions: These findings provide further insight into how the sigma 2 receptor/ligand interaction mediates cancer cell death and provides the basis for rationally combined targeted therapy regimens to be tested in vivo.

Abstract
BACKGROUND Surgical resection is the cornerstone of curative-intent therapy for patients with hilar cholangiocarcinoma (HC). The role of vascular resection (VR) in the treatment of HC in western centres is not well defined. METHODS Utilizing data from the U.S. Extrahepatic Biliary Malignancy Consortium, patients were grouped into those who underwent resection for HC based on VR status: no VR, portal vein resection (PVR), or hepatic artery resection (HAR). Perioperative and long-term survival outcomes were analyzed. RESULTS Between 1998 and 2015, 201 patients underwent resection for HC, of which 31 (15%) underwent VR: 19 patients (9%) underwent PVR alone and 12 patients (6%) underwent HAR either with (n = 2) or without PVR (n = 10). Patients selected for VR tended to be younger with higher stage disease. Rates of postoperative complications and 30-day mortality were similar when stratified by vascular resection status. On multivariate analysis, receipt of PVR or HAR did not significantly affect OS or RFS. CONCLUSION In a modern, multi-institutional cohort of patients undergoing curative-intent resection for HC, VR appears to be a safe procedure in a highly selected subset, although long-term survival outcomes appear equivalent. VR should be considered only in select patients based on tumor and patient characteristics.

Abstract
The objective of this study is to assess the accuracy of the American College of Surgeons National Surgical Quality Improvement Program online risk calculator for estimating risk after operation for gastric cancer using the United States Gastric Cancer Collaborative. Nine hundred and sixty-five patients who underwent resection of gastric adenocarcinoma between January 2000 and December 2012 at seven academic medical centers were included. Actual complication rates and outcomes for patients were compared. Most of the patients underwent total gastrectomy with Roux-en-Y reconstruction (404, 41.9%) and partial gastrectomy with gastrojejunostomy (239, 24.8%) or Roux-en-Y reconstruction (284, 29.4%). The C-statistic was highest for venous throm-boembolism (0.690) and lowest for renal failure at (0.540). All C-statistics were less than 0.7. Brier scores ranged from 0.010 for venous thromboembolism to 0.238 for any complication. General estimates of risk for the cohort were variable in terms of accuracy. Improving the ability of surgeons to estimate preoperative risk for patients is critically important so that efforts at risk reduction can be personalized to each patient. The American College of Surgeons National Surgical Quality Improvement Program risk calculator is a rapid and easy-to-use tool and validation of the calculator is important as its use becomes more common.

Abstract
BACKGROUND Curative-intent treatment for localized hilar cholangiocarcinoma (HC) requires surgical resection. However, the effect of adjuvant therapy (AT) on survival is unclear. We analyzed the impact of AT on overall (OS) and recurrence free survival (RFS) in patients undergoing curative resection. METHODS We reviewed patients with resected HC between 2000 and 2015 from the ten institutions participating in the U.S. Extrahepatic Biliary Malignancy Consortium. We analyzed the impact of AT on RFS and OS. The probability of RFS and OS were calculated in the method of Kaplan and Meier and analyzed using multivariate Cox regression analysis. RESULTS A total of 249 patients underwent curative resection for HC. Patients who received AT and those who did not had similar demographic and preoperative features. In a multivariate Cox regression analysis, AT conferred a significant protective effect on OS (HR 0.58, P = 0.013), and this was maintained in a propensity matched analysis (HR 0.66, P = 0.033). The protective effect of AT remained significant when node negative patients were excluded (HR 0.28, P = 0.001), while it disappeared (HR 0.76, P = 0.260) when node positive patients were excluded. CONCLUSIONS AT should be strongly considered after curative-intent resection for HC, particularly in patients with node positive disease.

Abstract
BACKGROUND The 7th AJCC T-stage system for adrenocortical carcinoma (ACC), based on size and extra-adrenal invasion, does not adequately stratify patients by survival. Lymphovascular invasion (LVI) is a known poor prognostic factor. We propose a novel T-stage system that incorporates LVI to better risk-stratify patients undergoing resection for ACC. METHOD Patients undergoing curative-intent resections for ACC from 1993 to 2014 at 13 institutions comprising the US ACC Group were included. Primary outcome was disease-specific survival (DSS). RESULTS Of the 265 patients with ACC, 149 were included for analysis. The current T-stage system failed to differentiate patients with T2 versus T3 disease (p = 0.10). Presence of LVI was associated with worse DSS versus no LVI (36 mo vs. 168 mo; p = 0.001). After accounting for the individual components of the current T-stage system (size, extra-adrenal invasion), LVI remained a poor prognostic factor on multivariable analysis (hazard ratio 2.14, 95% confidence interval 1.05-4.38, p = 0.04). LVI positivity further stratified patients with T2 and T3 disease (T2: 37 mo vs. median not reached; T3: 36 mo vs. 96 mo; p = 0.03) but did not influence survival in patients with T1 or T4 disease. By incorporating LVI, a new T-stage classification system was created: [T1: ≤ 5 cm, (-)local invasion, (+/-)LVI; T2: > 5 cm, (-)local invasion, (-)LVI OR any size, (+)local invasion, (-)LVI; T3: > 5 cm, (-)local invasion, (+)LVI OR any size, (+)local invasion, (+)LVI; T4: any size, (+)adjacent organ invasion, (+/-)LVI]. Each progressive new T-stage group was associated with worse median DSS (T1: 167 mo; T2: 96 mo; T3: 37 mo; T4: 15 mo; p < 0.001). CONCLUSIONS Compared with the current T-stage system, the proposed T-stage system, which incorporates LVI, better differentiates T2 and T3 disease and accurately stratifies patients by disease-specific survival. If externally validated, this T-stage classification should be considered for future AJCC staging systems.

Abstract
BACKGROUND The impact of adjuvant chemotherapy and chemo-radiation therapy in the treatment of resectable gastric cancer remains varied. We sought to define the clinical impact of lymph node ratio on the relative benefit of adjuvant chemotherapy or chemo-radiation therapy among patients having undergone curative-intent resection for gastric cancer. METHODS Using the multi-institutional US Gastric Cancer Collaborative database, 719 patients with gastric adenocarcinoma who underwent curative-intent resection between 2000 and 2013 were identified. Patients with metastasis or an R2 margin were excluded. The impact of lymph node ratio on overall survival among patients who received chemotherapy or chemo-radiation therapy was evaluated. RESULTS Median patient age was 65 years, and the majority of patients were male (56.2%). The majority of patients underwent either subtotal (40.6%) or total gastrectomy (41.0%), with the remainder undergoing distal gastrectomy or wedge resection (18.4%). On pathology, median tumor size was 4 cm; most patients had a T3 (33.0%) or T4 (27.9%) lesion with lymph node metastasis (59.7%). Margin status was R0 in 92.5% of patients. A total of 325 (45.2%) patients underwent resection alone, 253 (35.2%) patients received 5-FU or capecitabine-based chemo-radiation therapy, whereas the remaining 141 (19.6%) received chemotherapy. Median overall survival was 40.9 months, and 5-year overall survival was 40.3%. According to lymph node ratio categories, 5-year overall survival for patients with a lymph node ratio of 0, 0.01-0.10, >0.10-0.25, >0.25 were 54.1%, 53.1 %, 49.1 % and 19.8 %, respectively. Factors associated with worse overall survival included involvement of the gastroesophageal junction (hazard ratio 1.8), T-stage (3-4: hazard ratio 2.1), lymphovascular invasion (hazard ratio 1.4), and lymph node ratio (>0.25: hazard ratio 2.3; all P < .05). In contrast, receipt of adjuvant chemo-radiation therapy was associated with an improved overall survival in the multivariable model (versus resection alone: hazard ratio 0.40; versus chemotherapy: hazard ratio 0.45, both P < .001). The benefit of chemo-radiation therapy for resected gastric cancer was noted only among patients with lymph node ratio >0.25 (versus resection alone: hazard ratio R 0.34; versus chemotherapy: hazard ratio 0.45, both P < .001). In contrast, there was no noted overall survival benefit of chemotherapy or chemo-radiation therapy among patients with lymph node ratio ≤0.25 (all P > .05). CONCLUSION Adjuvant chemotherapy or chemo-radiation therapy was utilized in more than one-half of patients undergoing curative-intent resection for gastric cancer. Lymph node ratio may be a useful tool to select patients for adjuvant chemo-radiation therapy, because the benefit of chemo-radiation therapy was isolated to patients with greater degrees of lymphatic spread (ie, lymph node ratio >0.25).

Abstract
Perioperative blood transfusion is associated with decreased survival in pancreatic, gastric, and liver cancer. The effect of transfusion in adrenocortical carcinoma (ACC) has not been studied. Patients with available transfusion data undergoing curative-intent resection of ACC from 1993 to 2014 at 13 institutions comprising the United States Adrenocortical Carcinoma Group were included. Factors associated with blood transfusion were determined. Primary and secondary end points were recurrence-free survival (RFS) and overall survival (OS), respectively. Out of 265 patients, 149 were included for analysis. Out of these, 57 patients (38.3%) received perioperative transfusions. Compared to nontransfused patients, transfused patients more commonly had stage 4 disease (46% vs 24%, P = 0.01), larger tumors (15.8 vs 10.2 cm, P < 0.001), inferior vena cava involvement (24.6% vs 5.4%, P = 0.002), additional organ resection (78.9% vs 36.3%, P < 0.001), and major complications (29% vs 2%, P < 0.001). Transfusion was associated with decreased RFS (8.9 vs 24.7 months, P = 0.006) and OS (22.8 vs 91.0 months, P < 0.001). On univariate Cox regression, transfusion, stage IV, hormonal hypersecretion, and adjuvant therapy were associated with decreased RFS. On multivariable analysis, only transfusion [hazard ratio (HR) = 1.7, 95% confidence interval (CI) 51.0–2.9, P = 0.04], stage IV (HR = 3.2, 95% CI = 1.7–5.9, P < 0.001), and hormonal hypersecretion (HR = 2.6, 95% CI = 1.5–4.2, P < 0.001) were associated with worse RFS. When applying this model to OS, similar associations were seen (transfusion HR = 2.0, 95% CI = 1.1–3.8, P = 0.02; stage 4 HR = 6.2, 95% CI = 3.1–12.4, P < 0.001; hormonal hypersecretion HR = 3.5, 95% CI = 1.9–6.4, P < 0.001). There was no difference in outcomes between patients who received 1 to 2 units versus >2 units of packed red blood cells in median RFS (8.9 vs 8.4 months, P = 0.95) or OS (26.5 vs 18.6 months, P = 0.63). Peri-operative transfusion is associated with earlier recurrence and decreased survival after curative-intent resection of ACC. Strategies and protocols to minimize blood transfusion should be developed and followed.

Abstract
Perioperative blood transfusion is associated with decreased survival in pancreatic, gastric, and liver cancer. The effect of transfusion in adrenocortical carcinoma (ACC) has not been studied. Patients with available transfusion data undergoing curative-intent resection of ACC from 1993 to 2014 at 13 institutions comprising the United States Adrenocortical Carcinoma Group were included. Factors associated with blood transfusion were determined. Primary and secondary end points were recurrence-free survival (RFS) and overall survival (OS), respectively. Out of 265 patients, 149 were included for analysis. Out of these, 57 patients (38.3%) received perioperative transfusions. Compared to nontransfused patients, transfused patients more commonly had stage 4 disease (46% vs 24%, P = 0.01), larger tumors (15.8 vs 10.2 cm, P < 0.001), inferior vena cava involvement (24.6% vs 5.4%, P = 0.002), additional organ resection (78.9% vs 36.3%, P < 0.001), and major complications (29% vs 2%, P < 0.001). Transfusion was associated with decreased RFS (8.9 vs 24.7 months, P = 0.006) and OS (22.8 vs 91.0 months, P < 0.001). On univariate Cox regression, transfusion, stage IV, hormonal hypersecretion, and adjuvant therapy were associated with decreased RFS. On multivariable analysis, only transfusion [hazard ratio (HR) = 1.7, 95% confidence interval (CI) =1.0-2.9, P = 0.04], stage IV (HR = 3.2, 95% CI = 1.7-5.9, P < 0.001), and hormonal hypersecretion (HR = 2.6, 95% CI = 1.5-4.2, P < 0.001) were associated with worse RFS. When applying this model to OS, similar associations were seen (transfusion HR = 2.0, 95% CI = 1.1-3.8, P = 0.02; stage 4 HR = 6.2, 95% CI = 3.1-12.4, P < 0.001; hormonal hypersecretion HR = 3.5, 95% CI = 1.9-6.4, P < 0.001). There was no difference in outcomes between patients who received 1 to 2 units versus >2 units of packed red blood cells in median RFS (8.9 vs 8.4 months, P = 0.95) or OS (26.5 vs 18.6 months, P = 0.63).

Abstract
Importance The current recommendation is to perform re-resection for select patients with incidentally discovered gallbladder cancer. The optimal time interval for re-resection for both patient selection and long-term survival is not known. Objective To assess the association of time interval from the initial cholecystectomy to reoperation with overall survival. Design, Setting, and Participants This cohort study was conducted from January 1, 2000, to December 31, 2014 at 10 US academic institutions. A total of 207 patients with incidentally discovered gallbladder cancer who underwent reoperation and had available data on the date of their initial cholecystectomy were included. Exposures Time interval from the initial cholecystectomy to reoperation: group A: less than 4 weeks; group B: 4 to 8 weeks; and group C: greater than 8 weeks. Main Outcomes and Measures Primary outcome was overall survival. Results Of 449 patients with gallbladder cancer, 207 cases (46%) were discovered incidentally and underwent reoperation at 3 different time intervals from the date of the original cholecystectomy: group A: less than 4 weeks (25 patients, 12%); B: 4 to 8 weeks (91 patients, 44%); C: more than 8 weeks (91 patients, 44%). The mean (SD) ages of patients in groups A, B, and C were 65 (9), 64 (11), and 66 (12) years, respectively. All groups were similar for baseline demographics, extent of resection, presence of residual disease, T stage, resection margin status, lymph node involvement, and postoperative complications. Patients who underwent reoperation between 4 and 8 weeks had the longest median overall survival (group B: 40.4 months) compared with those who underwent early (group A: 17.4 months) or late (group C: 22.4 months) reoperation (log-rank P = .03). Group A and C time intervals (vs group B), presence of residual disease, an R2 resection, advanced T stage, and lymph node involvement were associated with decreased overall survival on univariable Cox regression. Only group A (hazard ratio, 2.63; 95% CI, 1.25-5.54) and group C (hazard ratio, 2.07; 95% CI, 1.17-3.66) time intervals (vs group B), R2 resection (hazard ratio, 2.69; 95% CI, 1.27-5.69), and advanced Tstage (hazard ratio, 1.85; 95% CI, 1.11-3.08) persisted on multivariable Cox regression analysis. Conclusions and Relevance The optimal time interval for re-resection for incidentally discovered gallbladder cancer appears to be between 4 and 8 weeks after the initial cholecystectomy.

Abstract
BACKGROUND This study was designed to develop a more robust predictive model, beyond T-stage alone, for incidental gallbladder cancer (IGBC) for discovering locoregional residual (LRD) and distant disease (DD) at reoperation, and estimating overall survival (OS). T-stage alone is currently used to guide treatment for incidental gallbladder cancer. Residual disease at re-resection is the most important factor in predicting outcomes. METHODS All patients with IGBC who underwent reoperation at 10 institutions from 2000 to 2015 were included. Routine pathology data from initial cholecystectomy was utilized to create the gallbladder cancer predictive risk score (GBRS). RESULTS Of 449 patients with gallbladder cancer, 262 (58 %) were incidentally discovered and underwent reoperation. Advanced T-stage, grade, and presence of lymphovascular (LVI) and perineural (PNI) invasion were all associated with increased rates of DD and LRD and decreased OS. Each pathologic characteristic was assigned a value (T1a: 0, T1b: 1, T2: 2, T3/4: 3; well-diff: 1, mod-diff: 2, poor-diff: 3; LVI-neg: 1, LVI-pos: 2; PNI-neg: 1, PNI-pos: 2), which added to a total GBRS score from 3 to 10. The scores were separated into three risk-groups (low: 3-4, intermediate: 5-7, high: 8-10). Each progressive GBRS group was associated with an increased incidence LRD and DD at the time of re-resection and reduced OS. CONCLUSIONS By accounting for subtle pathologic variations within each T-stage, this novel predictive risk-score better stratifies patients with incidentally discovered gallbladder cancer. Compared with T-stage alone, it more accurately identifies patients at risk for locoregional-residual and distant disease and predicts long-term survival as it redistributes T1b, T2, and T3 disease across separate risk-groups based on additional biologic features. This score may help to optimize treatment strategy for patients with incidentally discovered gallbladder cancer.

Abstract
BACKGROUND AND OBJECTIVES Minimally invasive surgery for adrenocortical carcinoma (ACC) is controversial. We sought to evaluate the perioperative and long-term outcomes following minimally invasive (MIS) and open resection (OA) of ACC in patients treated with curative intent surgery. METHODS Retrospective data from patients who underwent adrenalectomy for primary ACC at 13 tertiary care cancer centers were analyzed, including demographics, clinicopathological, and operative outcomes. Outcomes following MIS were compared to OA. RESULTS A total of 201 patients were evaluated including 47 MIS and 154 OA. There was no difference in utilization of MIS approach among institutions (p = 0.24) or 30-day morbidity (29.3 %, MIS, vs. 30.9 %, OA; p = 0.839). The only preoperatively determined predictor for MIS was smaller tumor size (p < 0.001). There was no difference in rates of intraoperative tumor rupture (p = 0.612) or R0 resection (p = 0.953). Only EBL (p = 0.038) and T stage (p = 0.045) were independent prognostic indicators of overall survival after adjusting for significant factors. The surgical approach was not associated with overall or disease-free survival. CONCLUSION MIS adrenalectomy may be utilized for preoperatively determined ACC ≤ 10.0 cm; however, OA should be utilized for adrenal masses with either preoperative or intraoperative evidence of local invasion or enlarged lymph nodes, regardless of size.

Abstract
331 Background: Pancreatic cancer is a devastating disease that is poorly responsive to traditional systemic therapies. Cancer-selective drug delivery can improve survival and reduce systemic toxicities. We have developed a pancreatic cancer drug delivery platform based on sigma-2 receptor ligands conjugated to small molecule drug cargos, which improves delivery and efficacy through efficient drug internalization. However, the mechanism of drug internalization via the sigma-2 receptor/ligand interaction remains unclear. Methods: Uptake of fluorescently conjugated sigma-2 ligand SW120 was studied in ASPC-1 human pancreatic cancer cells. Uptake was measured at 37C, 4C, after competitive inhibition with sigma-2 ligand SW43, and after pretreatment with Pitstop 2 (Abcam), an inhibiter of clathrin-mediated endocytosis. Uptake was visualized using live-cell imaging using A1Rsi confocal laser scanning microscope (Nikon). Image analysis was performed using FIJI (NIH) and Matlab (Mathworks). Results: SW120 (10 nM) was rapidly internalized into ASPC-1 cells at 37C with maximal fluorescence at 12 minutes. As a negative control, incubation of ASPC-1 cells with the unconjugated flourophore NBD Cl demonstrated no uptake after 15 minutes, indicating that uptake of SW120 depends on the specific sigma-2 receptor/ligand interaction. Fluorescence at 15 minutes was reduced by 85% in ASPC-1 cells incubated at 4C, indicating uptake of SW120 into cells is an energy dependent process. Pretreatment of cells with Pitstop 2 decreased total flourescence at 15 minutes by 76%, suggesting an important role of clathrin-mediated endocytosis in sigma-2 receptor uptake, while pretreatment with competitive inhibitor SW43 reduced uptake by 84%, suggesting that sigma-2 ligands are internalized via a specific receptor capable of saturation. Conclusions: Sigma-2 receptor ligands are rapidly internalized into pancreatic cancer cells via a specific, targetable, energy-dependent pathway that appears to rely on clathrin-mediated endocytosis. Further understanding of sigma-2 mediated drug internalization can help optimize targeted drug development and delivery for pancreatic cancer patients.

Abstract
BACKGROUND Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy with limited therapeutic options beyond surgical resection. The characteristics of actual long-term survivors following surgical resection for ACC have not been previously reported. METHOD Patients who underwent resection for ACC at one of 13 academic institutions participating in the US Adrenocortical Carcinoma Group from 1993 to 2014 were analyzed. Patients were stratified into four groups: early mortality (died within 2 years), late mortality (died within 2-5 years), actual 5-year survivor (survived at least 5 years), and actual 10-year survivor (survived at least 10 years). Patients with less than 5 years of follow-up were excluded. RESULTS Among the 180 patients available for analysis, there were 49 actual 5-year survivors (27%) and 12 actual 10-year survivors (7%). Patients who experienced early mortality had higher rates of cortisol-secreting tumors, nodal metastasis, synchronous distant metastasis, and R1 or R2 resections (all P < 0.05). The need for multi-visceral resection, perioperative blood transfusion, and adjuvant therapy correlated with early mortality. However, nodal involvement, distant metastasis, and R1 resection did not preclude patients from becoming actual 10-year survivors. Ten of twelve actual 10-year survivors were women, and of the seven 10-year survivors who experienced disease recurrence, five had undergone repeat surgery to resect the recurrence. CONCLUSION Surgery for ACC can offer a 1 in 4 chance of actual 5-year survival and a 1 in 15 chance of actual 10-year survival. Long-term survival was often achieved with repeat resection for local or distant recurrence, further underscoring the important role of surgery in managing patients with ACC. J. Surg.

Abstract
IMPORTANCE Adrenocortical carcinoma (ACC) is a rare but aggressive endocrine tumor, and the prognostic factors associated with long-term outcomes after surgical resection remain poorly defined. OBJECTIVES To define clinicopathological variables associated with recurrence-free survival (RFS) and overall survival (OS) after curative surgical resection of ACC and to propose nomograms for individual risk prediction. DESIGN, SETTING, AND PARTICIPANTS Nomograms to predict RFS and OS after surgical resection of ACC were proposed using a multi-institutional cohort of patients who underwent curative-intent surgery for ACC at 13 major institutions in the United States between March 17, 1994, and December 22, 2014. The dates of our study analysis were April 15, 2015, to May 12, 2015. MAIN OUTCOMES AND MEASURES The discriminative ability and calibration of the nomograms to predict RFS and OS were tested using C statistics, calibration plots, and Kaplan-Meier curves. RESULTS In total, 148 patients who underwent surgery for ACC were included in the study. The median patient age was 53 years, and 65.5% (97 of 148) of the patients were female. One-third of the patients (35.1% [52 of 148]) had a functional tumor, and the median tumor size was 11.2 cm. Most patients (77.7% [115 of 148]) underwent R0 resection, and 8.8% (13 of 148) of the patients had N1 disease. Using backward stepwise selection of clinically important variables with the Akaike information criterion, the following variables were incorporated in the prediction of RFS: tumor size of at least 12 cm (hazard ratio [HR], 3.00; 95% CI, 1.63-5.70; P < .001), positive nodal status (HR, 4.78; 95% CI, 1.47-15.50; P = .01), stage III/IV (HR, 1.80; 95% CI, 0.95-3.39; P = .07), cortisol-secreting tumor (HR, 2.38; 95% CI, 1.27-4.48; P = .01), and capsular invasion (HR, 1.96; 95% CI, 1.02-3.74; P = .04). Factors selected as predicting OS were tumor size of at least 12 cm (HR, 1.78; 95% CI, 1.00-3.17; P = .05), positive nodal status (HR, 5.89; 95% CI, 2.05-16.87; P = .001), and R1 margin (HR, 2.83; 95% CI, 1.51-5.30; P = .001). The discriminative ability and calibration of the nomograms revealed good predictive ability as indicated by the C statistics (0.74 for RFS and 0.70 for OS). CONCLUSIONS AND RELEVANCE Independent predictors of survival and recurrence risk after curative-intent surgery for ACC were selected to create nomograms predicting RFS and OS. The nomograms were able to stratify patients into prognostic groups and performed well on internal validation.

Abstract
BACKGROUND Lymph node metastasis is an established predictor of poor outcome for adrenocortical carcinoma (ACC); however, routine lymphadenectomy during surgical resection of ACC is not widely performed and its therapeutic role remains unclear. METHODS Patients undergoing margin-negative resection for localized ACC were identified from a multi-institutional database. Patients were stratified into 2 groups based on the surgeon's effort or not to perform a lymphadenectomy as documented in the operative note. Clinical, pathologic, and outcome data were compared between the 2 groups. RESULTS Of 120 patients who met inclusion criteria from 1993 to 2014, 32 (27 %) underwent lymphadenectomy. Factors associated with lymphadenectomy were tumor size (12 vs. 9.5 cm; p = .007), palpable mass at presentation (26 vs. 12 %; p = .07), suspicious lymph nodes on preoperative imaging (44 vs. 7 %; p < .001), and need for multivisceral resection (78 vs. 36 %; p < .001). Median number of lymph nodes harvested was higher in the lymphadenectomy group (5.5 vs. 0; p < .001). In-hospital mortality (0 vs. 1.3 %; p = .72) and grade 3/4 complication rates (0 vs. 12 %; p = .061) were not significantly different. Patients who underwent lymphadenectomy had improved overall survival (5-year 76 vs. 59 %; p = .041). The benefit of lymphadenectomy on overall survival persisted on multivariate analysis (HR = 0.17; p = .006) controlling for adverse preoperative and intraoperative factors associated with lymphadenectomy, such as tumor size, palpable mass, irregular tumor edges, suspicious nodes on imaging, and multivisceral resection. CONCLUSIONS In this multicenter study of adrenocortical carcinoma patients undergoing R0 resection, the surgeon's effort to dissect peritumoral lymph nodes was independently associated with improved overall survival.

Abstract
BACKGROUND This study utilized a multi-institutional database to evaluate risk factors for readmission in patients undergoing curative gastrectomy for gastric adenocarcinoma with the intent of describing both perioperative risk factors and the relationship of readmission to survival. METHODS Patients who underwent curative resection of gastric adenocarcinoma from 2000 to 2012 from seven academic institutions of the US Gastric Cancer Collaborative were analyzed. In-hospital deaths and palliative surgeries were excluded, and readmission was defined as within 30 days of discharge. Univariate and multivariable logistic regression analyses were employed and survival analysis conducted. RESULTS Of the 855 patients, 121 patients (14.2 %) were readmitted. Univariate analysis identified advanced age (p < 0.0128), American Society of Anesthesiology status ≥3 (p = 0.0045), preexisting cardiac disease (p < 0.0001), hypertension (p = 0.0142), history of smoking (p = 0.0254), increased preoperative blood urea nitrogen (BUN; p = 0.0426), concomitant pancreatectomy (p = 0.0056), increased operation time (p = 0.0384), estimated blood loss (p = 0.0196), 25th percentile length of stay (<7 days, p = 0.0166), 75th percentile length of stay (>12 days, p = 0.0256), postoperative complication (p < 0.0001), and total gastrectomy (p = 0.0167) as risk factors for readmission. Multivariable analysis identified cardiac disease (odds ratio (OR) 2.4, 95 % confidence interval (CI) 1.6-3.3, p < 0.0001), postoperative complication (OR 2.3, 95 % CI 1.6-5.4, p < 0.0001), and pancreatectomy (OR 2.2, 95 % CI 1.1-4.1, p = 0.0202) as independent risk factors for readmission. There was an association of decreased overall median survival in readmitted patients (39 months for readmitted vs. 103 months for non-readmitted). This was due to decreased survival in readmitted stage 1 (p = 0.0039), while there was no difference in survival for other stages. Stage I readmitted patients had a higher incidence of cardiac disease than stage I non-readmitted patients (58 vs. 24 %, respectively, p = 0.0002). CONCLUSIONS Within this multi-institutional study investigating readmission in patients undergoing curative resection for gastric cancer, cardiac disease, postoperative complication, and concomitant pancreatectomy were identified as significant risk factors for readmission. Readmission was associated with decreased overall median survival, but on further analysis, this was driven by differences in survival for stage I disease only.

Abstract
BACKGROUND Although the extent of resection frequently dictates the method of reconstruction following distal subtotal gastrectomy, it is unclear whether Roux-en-Y gastrojejunostomy compared with Billroth II gastrojejunostomy is associated with superior perioperative outcomes. METHODS Patients who underwent resection for gastric cancer with Roux-en-Y or Billroth II reconstruction between 2000 and 2012 in seven academic institutions (US Gastric Cancer Collaborative) were identified. Patients who underwent total gastrectomy, gastric wedge, or palliative resections (metastatic disease or R2 resections) were excluded. RESULTS Of a total of 965 patients, 447 met the inclusion criteria. A comparison between the Roux-en-Y (n = 257) and Billroth II (n = 190) groups demonstrated no differences in patient and tumor characteristics, except for Billroth II patients having a higher proportion of antral tumors (71 % vs. 50 %, p < 0.001). Roux-en-Y operations were slightly longer (244 min vs. 212 min, p < 0.001) and associated with somewhat higher blood loss (243 ml vs. 205 ml, p = 0.033). However, there were no significant differences in the length of hospital stay (8 days vs. 7 days), readmission rate (17 % vs. 18 %), 90-day mortality (5.1 % vs. 4.7 %), incidence (39 % vs. 41 %) and severity of complications, dependency on jejunostomy tube feeding at discharge (13 % vs. 12 %), same-patient decrease in serum albumin level from the preoperative to the postoperative value at 30, 60, and 90 days, receipt of adjuvant therapy (50 % vs. 53 %), or 5-year survival (44 % vs. 41 %). CONCLUSIONS Although long-term quality-of-life parameters were not compared, this study did not show an advantage of Roux-en-Y gastrojejunostomy over Billroth II gastrojejunostomy in short-term perioperative outcomes. Both techniques should be regarded as equally acceptable reconstructive options following partial gastrectomy for gastric cancer.

Abstract
BACKGROUND Current treatment guidelines recommend adjuvant mitotane after resection of adrenocortical carcinoma with high-risk features (eg, tumor rupture, positive margins, positive lymph nodes, high grade, elevated mitotic index, and advanced stage). Limited data exist on the outcomes associated with these practice guidelines. STUDY DESIGN Patients who underwent resection of adrenocortical carcinoma from 1993 to 2014 at the 13 academic institutions of the US Adrenocortical Carcinoma Group were included. Factors associated with mitotane administration were determined. Primary end points were recurrence-free survival (RFS) and overall survival (OS). RESULTS Of 207 patients, 88 (43%) received adjuvant mitotane. Receipt of mitotane was associated with hormonal secretion (58% vs 32%; p = 0.001), advanced TNM stage (stage IV: 42% vs 23%; p = 0.021), adjuvant chemotherapy (37% vs 5%; p < 0.001), and adjuvant radiation (17% vs 5%; p = 0.01), but was not associated with tumor rupture, margin status, or N-stage. Median follow-up was 44 months. Adjuvant mitotane was associated with decreased RFS (10.0 vs 27.9 months; p = 0.007) and OS (31.7 vs 58.9 months; p = 0.006). On multivariable analysis, mitotane was not independently associated with RFS or OS, and margin status, advanced TNM stage, and receipt of chemotherapy were associated with survival. After excluding all patients who received chemotherapy, adjuvant mitotane remained associated with decreased RFS and similar OS; multivariable analyses again showed no association with recurrence or survival. Stage-specific analyses in both cohorts revealed no association between adjuvant mitotane and improved RFS or OS. CONCLUSIONS When accounting for stage and adverse tumor and treatment-related factors, adjuvant mitotane after resection of adrenocortical carcinoma is not associated with improved RFS or OS. Current guidelines should be revisited and prospective trials are needed.

Abstract
BACKGROUND Postoperative complications (POCs) can negatively impact survival after oncologic resection. POCs may also decrease the rate of adjuvant therapy completion. We evaluated the impact of complications on gastric cancer survival and analyzed the combined effect of complications and adjuvant therapy on survival. METHODS We analyzed 824 patients from 7 institutions of the U.S. Gastric Cancer Collaborative who underwent curative resection for gastric adenocarcinoma between 2000 and 2012. POC were graded using the modified Clavien-Dindo system. Survival probabilities were estimated using the method of Kaplan and Meier and analyzed using multivariate Cox regression. RESULTS Median follow-up was 35 months. The overall complication rate was 41 %. The 5-year overall survival (OS) and recurrence-free survival (RFS) of patients who experienced complications were 27 and 23 %, respectively, compared with 43 and 40 % in patients who did not have complications (p < 0.0001 for OS and RFS). On multivariate analysis, POC remained an independent predictor for decreased OS and RFS (HR 1.3, 95 % CI 1.1-1.6, p = 0.03 for OS; HR 1.3, 95 % CI 1.01-1.6, p = 0.03 for RFS). Patients who experienced POC were less likely to receive adjuvant therapy (OR 0.5, 95 % CI 0.3-0.7, p < 0.001). The interaction of complications and failure to receive adjuvant therapy significantly increased the hazard of death compared with patients who had neither complications nor adjuvant therapy (HR 2.3, 95 % CI 1.6-3.2, p < 0.001). CONCLUSIONS Postoperative complications adversely affect long-term outcomes after gastrectomy for gastric cancer. Not receiving adjuvant therapy in the face of POC portends an especially poor prognosis following gastrectomy for gastric cancer.

Abstract
BACKGROUND AND OBJECTIVES The optimal extent of lymphadenectomy in the treatment of gastric adenocarcinoma is debated. We compared gastrectomy outcomes following limited (D1) or extended (D2) lymphadenectomy. METHODS Using the multi-institutional US Gastric Cancer Collaborative database, we reviewed the morbidity, mortality, recurrence, and overall survival (OS) of patients receiving D1 or D2 lymphadenectomies. RESULTS Between 2000 and 2012, 266 and 461 patients received a D1 and D2 lymphadenectomy, respectively. ASA class, mean number of comorbidities, grade, and stage were similar between groups. While major morbidity was similar (P = 0.85), mortality was worse for those receiving a D1 lymphadenectomy (4.9% vs. 1.3%, P = 0.004). D2 lymphadenectomy was associated with improved median OS in stage I (4.7 years for D1 vs. not reached for D2, P = 0.003), stage II (3.6 years for D1 vs. 6.3 for D2, P = 0.42), and stage III patients (1.3 years for D1 vs. 2.1 for D2, P = 0.01). After adjusting for predictors of OS, D2 lymphadenectomy remained a significant predictor of improved survival (HR 1.5, 95%CI 1.1-2.0, P = 0.008). CONCLUSIONS D2 lymphadenectomy can be performed without increased risk of morbidity and mortality. Additionally, D2 lymphadenectomy is associated with improved survival especially in early stages, and should be considered for gastric adenocarcinoma patients. J. Surg.

Abstract
BACKGROUND We sought to define the impact of cortisol-secreting status on outcomes after surgical resection of adrenocortical carcinoma (ACC). METHODS The U.S ACC group database was queried to identify patients who underwent ACC resection between 1993 and 2014. The short-term and long-term outcomes were assessed. RESULTS The incidence of all functional and cortisol-secreting tumors was 40.6% and 22.6%, respectively. On multivariable analysis, cortisol secretion remained associated with an increased risk of postoperative complications (odds ratio = 2.25, 95 % confidence interval = 1.04 to 4.88; P = .04). At a median follow-up of 17.6 months, 118 patients (50.4%) had developed a recurrence. On multivariable analysis, after adjusting for patient and disease-related factors cortisol secretion independently predicted shorter recurrence-free survival (Hazard ratio = 2.05, 95% confidence interval = 1.16 to 3.60; P = .01). CONCLUSIONS Cortisol secretion was associated with an increased risk of postoperative morbidity. Recurrence remains high among patients with ACC after surgery; cortisol secretion was independently associated with a shorter recurrence-free survival. Tailoring postoperative surveillance of ACC patients based on their cortisol secreting status may be important.

Abstract
BACKGROUND Limited data exist on the prognosis of preoperative Helicobacter pylori (H. pylori) infection in gastric adenocarcinoma (GAC). METHODS Patients who underwent curative-intent resection for GAC from 2000 to 2012 at seven academic institutions comprising the United States Gastric Cancer Collaborative were included in the study. The primary end points of the study were overall survival (OS), recurrence-free survival (RFS), and disease-specific survival (DSS). RESULTS Of 559 patients, 104 (18.6 %) who tested positive for H. pylori were younger (62.1 vs 65.1 years; p = 0.041), had a higher frequency of distal tumors (82.7 vs 71.9 %; p = 0.033), and had higher rates of adjuvant radiation therapy (47.0 vs 34.9 %; p = 0.032). There were no differences in American Society of Anesthesiology (ASA) class, margin status, grade, perineural invasion, lymphovascular invasion, nodal metastases, or tumor-node-metastasis (TNM) stage. H. pylori positivity was associated with longer OS (84.3 vs 44.2 months; p = 0.008) for all patients. This relationship with OS persisted in the multivariable analysis (HR 0.54; 95 % CI 0.30-0.99; p = 0.046). H. pylori was not associated with RFS or DSS in all patients. In the stage 3 patients, H. pylori was associated with longer OS (44.5 vs 24.7 months; p = 0.018), a trend of longer RFS (31.4 vs 21.6 months; p = 0.232), and longer DSS (44.8 vs 27.2 months; p = 0.034). CONCLUSIONS Patients with and without preoperative H. pylori infection had few differences in adverse pathologic features at the time of gastric adenocarcinoma resection. Despite similar disease presentations, preoperative H. pylori infection was independently associated with improved OS. Further studies examining the interaction between H. pylori and tumor immunology and genetics are merited.

Abstract
Medullary thyroid carcinoma (MTC) is a neuroendocrine malignancy of the thyroid C cells that occurs in hereditary and sporadic clinical settings. Metastatic spread commonly occurs to cervical and mediastinal lymph nodes. MTC cells do not concentrate radioactive iodine and are not sensitive to hormonal manipulation, and therefore surgery is the most effective option for curative therapy, reduction in tumor burden, or effective palliation. In patients undergoing preventative surgery for hereditary MTC, central lymph node dissection should be considered if the calcitonin level is elevated. Preservation of parathyroid function in these young patients is of paramount importance. In patients with established primary tumors, systematic surgical removal of lymph node basins (compartmental dissection) should be guided by ultrasound mapping of lymph node metastases and level of serum calcitonin. A "berry-picking" approach is discouraged. Newly approved targeted molecular therapies offer wider treatment options for patients with progressive or metastatic disease.

Abstract
BACKGROUND Current staging and treatment guidelines for gastric adenocarcinoma do not differentiate between linitis plastic (LP) and non-LP cancers. Significant controversy exists regarding the surgical management of LP patients. METHODS Using the multi-institutional U.S. Gastric Cancer Collaborative database, 869 gastric cancer patients who underwent resection between 2000 and 2012 were identified. Clinicopathologic and outcomes data of 58 LP patients were compared to 811 non-LP patients. RESULTS Stage III/IV disease was more common at presentation in LP patients compared with non-LP patients (90 vs. 44 %, p < 0.01). Despite the fact that most LP patients underwent total gastrectomy (88 vs. 39 %, p < 0.01), final positive margins were more common in LP patients (33 vs. 7 %, p < 0.01). The use of frozen section allowed 15 intraoperative positive margins in 38 patients to be converted to negative final margins. Median overall survival (OS) was significantly worse in patients with LP (11.6 vs. 37.8 months, p < 0.01). There was no difference in median OS of LP patients based on stage (I/II, 17.3 mo; III, 10.6 mo; IV, 12.0 mo; p = 0.46). LP and non-LP patients who underwent optimal resection (negative margin and D2/3 lymphadenectomy) had better survival compared with those with nonoptimal resections. The median OS for optimally resected stage III LP (n = 22) and stage III non-LP (n = 185) patients was nearly identical (26.7 vs. 25.3 mo; p = 0.69). CONCLUSIONS Future staging systems and treatment guidelines should differentiate between LP and non-LP gastric cancers. Long-term survival in select LP patients who undergo optimal resections is comparable to optimally resected non-LP patients.

Abstract
BACKGROUND The purpose of this study was to compare outcomes following resection of gastric remnant (GRC) and conventional gastric cancer. METHODS Patients who underwent resection for gastric cancer in 8 academic institutions from 2000-2012 were evaluated to compare morbidity, mortality, and survival based on history of prior gastrectomy. RESULTS Of the 979 patients who underwent gastrectomy with curative-intent during the 12-year study period, 55 patients (5.8%) presented with GRC and 924 patients (94.4%) presented with conventional gastric cancer. Patients with GRC were slightly older (median 69 vs. 66 years). GRC was associated with higher rates of complication (56% vs. 41%, P = 0.028), longer operative times (301 vs. 237 min, P < 0.001), higher intraoperative blood loss (300 vs. 200 ml, P = 0.012), and greater need for blood transfusion (43% vs. 23%, P = 0.001). There were no significant differences in 30-day (3.6% vs. 4%) or 90-day mortality (9% vs. 8%) between the two groups. Overall survival rates were similar between GRC and conventional gastric cancer (5-year 20.3% vs. 38.6%, P = 0.446). Multivariate analysis revealed that history of gastrectomy was not predictive of survival while established predictors (older age, advanced T-stage, nodal involvement, blood transfusion, multivisceral resection, and any complication) were associated with poor survival. CONCLUSIONS Despite higher morbidity, prognosis after resection of gastric remnant cancer is similar to conventional gastric cancer.

Abstract
BACKGROUND The influence of surgical margin status on long-term outcomes of patients undergoing adrenal resection for ACC remains not well defined. We studied the impact of surgical tumor margin status on recurrence-free survival (RFS) and overall survival (OS) of patients undergoing resection for ACC. METHODS A total of 165 patients who underwent adrenal resection for ACC and met inclusion criteria were identified form a multi-institutional database. Clinicopathological data, pathologic margin status, and long-term outcomes were assessed. Patients were stratified into two groups based on margin status: R0 (margin >1 mm) versus R1. RESULTS R0 resection was achieved in 126 patients (76.4 %), whereas 39 patients (23.6 %) had an R1 resection. Median and 5-year OS for patients undergoing R0 resection were 96.3 months and 64.8 % versus 25.1 months and 33.8 % for patients undergoing an R1 resection (both p < 0.001). On multivariable analysis, surgical margin status was an independent predictor of worse OS (hazard ratio [HR] 2.22, 95 % confidence interval [CI] 1.03-4.77; p = 0.04). The incidence of recurrence also differed between the two groups; 5-year RFS was 30.3 % among patients with an R0 resection versus 13.8 % among patients who had an R1 resection (p = 0.03). Lymph node metastasis (N1) was an independent predictor of RFS (HR 2.70, 95 % CI 1.04-6.99; p = 0.04). CONCLUSIONS A positive margin after ACC resection was associated with worse long-term survival. Patient selection and an emphasis on surgical technique to achieve R0 margins are pivotal to optimizing the best chance for long-term outcome among patients with ACC.

Abstract
BACKGROUND Adrenocortical carcinoma (ACC) is a rare malignancy. The aim of this study was to determine the incidence and patterns of recurrence after curative-intent surgery for ACC. METHODS Patients who underwent curative-intent resection for ACC between 1993 and 2014 were identified from 13 academic institutions participating in the United States ACC study group. Patients with metastasis or an R2 margin were excluded. Patterns and rates of recurrence were determined and classified as locoregional and distant recurrence. RESULTS A total of 180 patients with a median age of 52 years (interquartile range 43-61) were identified. Most patients underwent open surgery (n = 111, 64.5 %) and had an R0 resection margin (n = 117, 75.0 %). At last follow-up, 116 patients (64.4 %) had experienced recurrence (locoregional only, n = 41, 36.3 %; distant only, n = 51, 45.1 %; locoregional and distant, n = 21, 18.6 %). Median time to recurrence was 18.8 months. Several factors were associated with locoregional recurrence, including left-sided ACC location (odds ratio [OR] 2.71, 95 % confidence interval [CI] 1.06-6.89) and T3/T4 disease (reference T1/T2, OR 3.04, 95 % CI 1.19-7.80) (both p < 0.05). Distant recurrence was associated with larger tumor size (OR 1.11, 95 % CI 1.01-1.24) and T3/T4 disease (reference T1/T2, OR 5.23, 95 % CI 1.70-16.10) (both p < 0.05). Patients with combined locoregional and distant recurrence had worse survival (3- and 5-year survival: 39.5, 19.7 %) versus patients with distant-only (3- and 5-year survival 55.1, 43.3 %) or locoregional-only recurrence (3- and 5-year survival 81.4, 64.1 %) (p = 0.01). CONCLUSIONS Nearly two-thirds of patients experienced disease recurrence after resection of ACC. Although a subset of patients experienced recurrence with locoregional disease only, many patients experienced recurrence with distant disease as a component of recurrence and had a poor prognosis.

Abstract
BACKGROUND A 5 cm margin is advocated for distal gastric adenocarcinoma (GAC). The optimal proximal resection margin (PM) length for proximal GAC is not established. METHODS Patients who underwent curative-intent resection for proximal GAC from 2000 to 2012 at 7 centers in the US Gastric Cancer Collaborative were included. PM length was sequentially dichotomized and analyzed at 0.5 cm increments (0.5-6.5 cm). Outcomes after negative margin (R0) and positive microscopic margin (R1) resections were compared. Primary endpoints were local recurrence (LR) and overall survival (OS). RESULTS All patients (n = 162) had R0 distal margins. 151 (93.2%) had an R0-PM with mean length of 2.6 cm (median:1.7 cm; range:0.1-15 cm). A greater PM distance was not associated with LR or OS. An R1-PM was associated with higher N-stage (N3:73% vs. 26%; P = 0.007) and increased LR (HR6.1; P = 0.009) but not associated with decreased OS. On multivariate analysis, an R1-PM was also not independently associated with LR. CONCLUSIONS For resection of proximal gastric adenocarcinoma, proximal margin length is not associated with local recurrence or overall survival. An R1 margin is associated with advanced N-stage but is not independently associated with recurrence or survival. When performing resection of proximal gastric adenocarcinoma, efforts to achieve a specific margin distance, especially if it necessitates an esophagectomy, should be abandoned.

Abstract
Medullary thyroid carcinoma (MTC) is a neuroendocrine malignancy of the thyroid C cells, and can commonly spread to cervical and mediastinal lymph nodes. MTC cells do not concentrate radioactive iodine and are not sensitive to hormonal manipulation, and therefore surgery is the only effective option for curative therapy, reduction in tumor burden or effective palliation. In patients undergoing preventative operations for hereditary MTC, central lymph node dissection should be considered if the calcitonin level is above 40 pg/ml. Systematic removal of at-risk or involved lymph node compartments should be performed in all patients with palpable primary tumors and recurrent disease, and a ‘berry-picking’ approach should be avoided.

Abstract
BACKGROUND The systemic inflammatory response may be associated with tumor progression. We sought to analyze the impact of neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) on recurrence-free survival (RFS) and disease-specific survival (DSS) among patients who underwent surgery for adrenocortical carcinoma (ACC). METHODS Patients undergoing surgery for ACC were identified from a multi-center database. Cut-off values of 5 and 190 were defined as elevated NLR and PLR, respectively, and long-term outcome was assessed. RESULTS Among 84 patients with ACC, 29 (34.%) had NLR > 5 while 32 (40.5%) had PLR > 190. NLR and PLR were associated with larger tumors (NLR > 5: ≤ 5 cm, 0% vs. >5 cm, 39.7%; PLR > 190: ≤ 5cm, 0% vs. >5 cm, 45.7%), as well as need to resect of other organs (NLR > 5: other organ resected 48.8% vs. not resected 20.9%; PLR > 190: other organ resected 25.0% vs. not resected 56.4%)(all P < 0.05). Five-year RFS was associated with an elevated NLR (NLR ≤ 5, 14.2% vs. NLR> 5, 10.5%) and PLR (PLR ≤ 190: 19.4% vs. PLR > 190: 5.2%) (both P < 0.05). On multivariate survival analyses, PLR remained a predictor of RFS (HR 1.72), while NLR was associated with both DSS (HR 2.21) and RFS (HR 1.99) (both P < 0.05). CONCLUSIONS Immune markers such as NLR and PLR may be useful to stratify patients with regards to prognosis following surgery for ACC.

Abstract
BACKGROUND Conflicting data exist on the prognostic implication of signet-ring cell (SRC) histology in gastric adenocarcinoma (GAC). METHODS All patients who underwent curative-intent resection of GAC from the seven institutions of the U.S. Gastric Cancer Collaborative between 2000 and 2012 were included. Primary end points were recurrence-free survival (RFS) and overall survival (OS). Stage-specific analyses were performed. RESULTS A total of 768 patients met the inclusion criteria. SRC was present in 40.6 % of patients and was associated with female sex (52.9 vs. 38.6 %; p < 0.001), younger age (61 vs. 67 years; p < 0.001), poor differentiation (94.8 vs. 50.3 %; p < 0.001), perineural invasion (PNI) (41.4 vs. 23 %; p < 0.001), microscopically positive resection margins (R1, 24.7 vs. 8.6 %; p < 0.001), distal location (82.2 vs. 70.1 %; p < 0.001), receipt of adjuvant therapy (63 vs. 51.2 %; p = 0.002), and more advanced stage (stage 3: 55.2 vs. 36.5 %; p < 0.001). SRC was associated with earlier recurrence (56.7 months vs. median not reached; p = 0.009) and decreased OS (33.7 vs. 46.6 months; p = 0.011). When accounting for other adverse pathologic features, PNI (hazard ratio [HR] 1.57; p = 0.016) and higher stage (HR 2.64; p < 0.001) were associated with decreased RFS, but SRC was not. Although PNI (HR 1.52; p = 0.007), higher stage (HR 2.11; p < 0.001), greater size (HR 1.05; p = 0.016), and adjuvant therapy (HR 0.50; p < 0.001) were associated with OS, SRC was not. Similarly, when accounting for adverse pathologic factors on multivariate analysis, stage-specific analyses showed no association between SRC and RFS or OS. CONCLUSIONS SRC histology is associated with adverse pathologic features including poor differentiation, higher stage, and microscopically positive resection margins but is not independently associated with reduced RFS or OS. Identification of signet-ring histology during preoperative evaluation should not, in isolation, dictate treatment strategy.

Abstract
BACKGROUND Resection of an adjacent organ during gastrectomy for gastric cancer is occasionally necessary to achieve margin clearance. The short- and long-term outcomes of this approach remain unclear. METHODS Patients who underwent gastric cancer resection in seven U.S. academic institutions from 2000 to 2012 were evaluated to compare perioperative morbidity, mortality, and survival outcomes, stratified by the need for and type of multivisceral resection (MVR). RESULTS Of 835 patients undergoing curative-intent gastrectomy, 159 (19 %) had MVR. The most common adjacent organs resected were the spleen (48 %), pancreas (27 %), liver segments 2/3 (14 %), and colon (13 %). As extent of resection increased (gastrectomy only, n = 676; MVR without pancreatectomy, n = 116; and MVR with pancreatectomy, n = 43), perioperative morbidity was higher: any complication (45, 60, 59 %, p = 0.012), major complication (17, 31, 33 %, p = 0.001), anastomotic leak (5, 11, 19 %, p < 0.001), and respiratory failure (9, 15, 22 %, p = 0.012). However, perioperative mortality did not significantly increase (30-day: 3, 4, 2 %, p = 0.74; 90-day: 6, 8, 9 %, p = 0.61). Overall survival after resection decreased as extent of resection increased (5-year: 42, 28, 6 %). After controlling for age, race, T stage, N stage, grade, margin status, perineural invasion, adjuvant therapy, and blood transfusion, MVR with pancreatectomy (HR 1.67, p = 0.044), but not MVR without pancreatectomy (HR 0.97, p = 0.759), remained an independent predictor of poor survival. CONCLUSION In this modern, multi-institutional cohort of gastric cancer patients, multivisceral resection was associated with higher perioperative morbidity but not significantly higher perioperative mortality. If concomitant pancreatectomy is anticipated, patients should be selected with extreme caution because long-term survival remains poor.

Abstract
BACKGROUND The prognostic effect of perioperative blood transfusion on recurrence and survival in patients undergoing resection of gastric adenocarcinoma (GAC) remains controversial. STUDY DESIGN All patients who underwent resection for GAC from 2000 to 2012 at the 7 institutions of the US Gastric Cancer Collaborative were identified. The effect of transfusion on recurrence-free (RFS) and overall survival (OS) in the context of adverse clinicopathologic variables was examined by univariate and multivariate regression analyses. RESULTS Of 965 patients, 765 underwent curative intent R0 resection. Median follow-up was 44 months; 30-day mortalities were excluded. Median estimated blood loss (EBL) was 200 mL, and 168 patients (22%) received perioperative allogeneic blood transfusions. Transfused patients were less likely to receive adjuvant therapy (44% vs 56%; p = 0.01). Transfusion was associated with significantly decreased median RFS (13.5 vs 37.2 months, p < 0.001). Median OS was similarly decreased in patients receiving transfusions (18.6 vs 49.8 months, p < 0.001). On multivariate analysis, transfusion remained an independent risk factor for decreased RFS (hazard ratio [HR] 1.63; 95% CI 1.13 to 2.37; p = 0.010) and decreased OS (HR 1.79; 95% CI 1.21 to 2.67; p = 0.004), regardless of EBL or need for splenectomy. Timing (intraoperative vs postoperative) and volume of transfusion did not alter the negative prognostic effect of transfusion on survival. CONCLUSIONS Perioperative allogeneic blood transfusion is associated with decreased RFS and OS after resection of gastric cancer, independent of adverse clinicopathologic factors. This supports the judicious use of perioperative transfusion during resection of gastric cancer.

Abstract
BACKGROUND The effect of routine drainage after abdominal surgery with enteric anastomoses is controversial. In particular, the role of peritoneal drain (PD) placement after total gastrectomy for adenocarcinoma is not well established. METHODS Patients who underwent total gastrectomy for gastric adenocarcinoma (GAC) at seven institutions from the US Gastric Cancer Collaborative, from 2000 to 2012, were identified. The association of PD placement with postoperative outcomes was analyzed. RESULTS Overall, 344 patients were identified and 253 (74 %) patients received a PD. The anastomotic leak rate was 9 %. Those with PD placement had similar American Society of Anesthesiologists score, tumor size, TNM stage, and the need for additional organ resection when compared with their counterparts. No difference was observed in the rate of any complication (54 vs. 48 %; p = 0.45), major complication (25 vs. 24 %; p = 0.90), or 30-day mortality (7 vs. 4 %; p = 0.51) between the two groups. In addition, no difference in anastomotic leak (9 vs. 10 %; p = 0.90), the need for secondary drainage (10 vs. 9 %; p = 0.92), or reoperation (13 vs. 8 %; p = 0.28) was identified. On multivariate analysis, PD placement was not associated with decreased postoperative complications. Subset analysis, stratified by patients who did not undergo concomitant pancreatectomy (n = 319) or those who experienced anastomotic leak (n = 31), similarly demonstrated no association of PD placement with reduced complications or mortality. CONCLUSIONS PD placement after total gastrectomy for GAC is associated with neither a decrease in the frequency and severity of adverse postoperative outcomes, including anastomotic leak and mortality, nor a decrease in the need for secondary drainage procedures or reoperation. Routine use of PDs is not warranted.

Abstract
BACKGROUND Examination of at least 16 lymph nodes (LNs) has been traditionally recommended during gastric adenocarcinoma resection to optimize staging, but the impact of this strategy on survival is uncertain. Because recent randomized trials have demonstrated a therapeutic benefit from extended lymphadenectomy, we sought to investigate the impact of the number of LNs removed on prognosis after gastric adenocarcinoma resection. STUDY DESIGN We analyzed patients who underwent gastrectomy for gastric adenocarcinoma from 2000 to 2012, at 7 US academic institutions. Patients with M1 disease or R2 resections were excluded. Disease-specific survival (DSS) was calculated using the Kaplan-Meier method and compared using log-rank and Cox regression analyses. RESULTS Of 742 patients, 257 (35%) had 7 to 15 LNs removed and 485 (65%) had ≥16 LNs removed. Disease-specific survival was not significantly longer after removal of ≥16 vs 7 to 15 LNs (10-year survival, 55% vs 47%, respectively; p = 0.53) for the entire cohort, but was significantly improved in the subset of patients with stage IA to IIIA (10-year survival, 74% vs 57%, respectively; p = 0.018) or N0-2 disease (72% vs 55%, respectively; p = 0.023). Similarly, for patients who were classified to more likely be "true N0-2," based on frequentist analysis incorporating both the number of positive and of total LNs removed, the hazard ratio for disease-related death (adjusted for T stage, R status, grade, receipt of neoadjuvant and adjuvant therapy, and institution) significantly decreased as the number of LNs removed increased. CONCLUSIONS The number of LNs removed during gastrectomy for adenocarcinoma appears itself to have prognostic implications for long-term survival.

Abstract
BACKGROUND There are no validated methods to preoperatively identify patients with increased risk of discharge to skilled nursing facilities following resection of gastric cancer. We sought to identify preoperative predictors of non-home discharge to optimize transition of care to skilled nursing facility. METHODS Patients who underwent resection of gastric cancer from 2000 to 2012 from seven participating institutions of the US Gastric Cancer Collaborative were analyzed. Fisher's exact tests, Student t tests, and logistic regression analyses identified preoperative variables associated with non-home discharge. A prediction tool was created and validated through c-indices. Survival analysis was conducted according to the methods of Kaplan and Meier. RESULTS Out of the 918 patients identified, 93 (10 %) were discharged to nonhome location. Univariate analysis identified advancing age, American Society of Anesthesiology (ASA) score, hypertension, decreasing preoperative albumin, and lack of neoadjuvant chemotherapy as risk factors for non-home discharge (NHD). Multivariable analysis identified advanced age (odds ratio (OR) = 1.07, 95 % confidence interval (CI) = 1.04-1.10, p < 0.0001), depressed preoperative albumin (OR = 2.17, 95 % CI = 1.47-3.19, p = 0.0001), and total gastrectomy (OR = 2.56, 95 % CI = 1.53-4.3, p = 0.0003) as risk factors for NHD. The c-index of the model and the validation population were 0.76 and 0.8, respectively. Additionally, there was an association of decreased overall survival in patients discharged to nonhome location (35.5 months, home discharge, vs 12 months, NHD, p < 0.0001). CONCLUSIONS Older patients with compromised nutritional status have greater risk of NHD following resection of gastric cancer. The prediction tool can augment preoperative planning to optimize transition of care to skilled nursing facility.

Abstract
115 Background: The optimal extent of lymphadenectomy in the treatment of gastric adenocarcinoma continues to be a subject of intense debate. We aimed to compare gastrectomy outcomes following limited (D1) or extended (D2) lymphadenectomy. Methods: Using the multi-institutional U.S. Gastric Cancer Collaborative database, we reviewed the morbidity, mortality, recurrence, and overall survival (OS) of 727 patients receiving D1 or D2 lymphadenectomies. Patients with stage IV disease, prior gastrectomy, and age 85 or greater were excluded. Multivariate analyses included variables with p values less than 0.1. Results: Between 2000 and 2014, 266 (36.6%) and 461 (63.4%) patients received a D1 and D2 lymphadenectomy, respectively. ASA class, mean number of comorbidities, grade, stage, and signet ring cell subtypes were similar between groups. Neoadjuvant and adjuvant chemotherapy was more common in the D2 group (p<0.001). The mean number of lymph nodes recovered was significantly higher in patients receiving a D2 lymphadenectomy (21.5 for D2 vs. 17.1 for D1, p<0.001). Median follow up was 1.3 years. While Clavien III/IV major morbidity was similar (15.0% for D1 vs. 14.5% for D2, p=0.85), mortality was worse for those receiving a D1 lymphadenectomy (4.9% vs. 1.3%, p=0.004). Recurrence rates for patients receiving D1 and D2 lymphadenectomies were 25.8% and 27.0%, respectively (p=0.74). D2 lymphadenectomy was associated with improved median OS in stage I (4.7 years for D1 vs. not reached for D2, p=0.003) stage II (3.6 years for D1 vs. 6.3 for D2, p=0.42), and stage III patients (1.3 years for D1 vs. 2.1 for D2, p=0.01). After adjusting for significant predictors of OS which included ASA, stage, grade, neoadjuvant chemotherapy, and adjuvant radiation, D2 lymphadenectomy remained a significant predictor of improved survival when compared with D1 lymphadenectomy (HR 1.5, 95% CI 1.1-2.0, p=0.008). Conclusions: D2 lymphadenectomy is associated with improved survival that is more prominent in early stages of disease. It can be performed safely without increased risk of morbidity and perioperative mortality and should be the preferred lymphadenectomy technique for the treatment of gastric adenocarcinoma.
