Abstract
BACKGROUND Pancreatic acinar cell carcinoma (PACC) is a rare exocrine tumor of the pancreas. We evaluated the effect disease stage, surgical intervention, and institutional volume status plays in survival. METHODS We queried the Oregon State Cancer Registry for patients with PACC from 1997 to 2018. Treatment and referral patterns were analyzed, and overall survival (OS) was evaluated with Kaplan-Meier and Cox-proportional hazard analysis. RESULTS 43 patients were identified. Median OS was 33.1 and 7.1 months in those with locoregional and metastatic disease respectively (p = 0.008). Surgical intervention was associated with improved OS (hazard ratio 0.28, p < 0.0001). High volume center (HVC) care trended towards improving OS. While the majority of cases were diagnosed at low volume centers (74%), referral to HVCs was rare (n = 4) and limited to advanced (stage III/IV) disease. CONCLUSION Stage and surgical resection influence survival outcomes in PACC, more data is needed to delineate the impact of institutional volume status.

Abstract
Ripretinib and avapritinib have demonstrated activity in the late-line treatment of gastrointestinal stomal tumors (GISTs). We investigated whether patients previously treated with ripretinib benefit from avapritinib, and vice versa. Patients diagnosed with metastatic/unresectable GIST and treated with both drugs at two institutions in 2000-2021 were included. Patients were grouped by drug sequence: ripretinib-avapritinib (RA) or avapritinib-ripretinib (AR). Radiographic response was evaluated using RECIST 1.1. Kaplan-Meier and log-rank tests were used to compare time-to-progression (TTP) and overall survival (OS). Thirty-four patients (17 per group) were identified, with a median age of 48 years. The most common primary site was the small bowel (17/34, 50%), followed by the stomach (10/34, 29.4%). Baseline characteristics and tumor mutations were not significantly different between groups. Response rates (RRs) for ripretinib were 18% for RA and 12% for AR; RRs for avapritinib were 12% for AR and 18% for RA. Median TTPs for ripretinib were 3.65 months (95%CI 2-5.95) for RA and 4.73 months (1.87-15.84) for AR. Median TTPs for avapritinib were 5.39 months (2.86-18.99) for AR and 4.11 months (1.91-11.4) for RA. Median OS rates following RA or AR initiation were 29.63 (95%CI 13.8-50.53) and 33.7 (20.03-50.57) months, respectively. Both ripretinib and avapritinib were efficacious in the late-line treatment of GIST, with no evidence that efficacy depended on sequencing.

Abstract
The RNA-binding protein human antigen R (HuR) is a well-established regulator of gene expression at the posttranscriptional level. Its dysregulation has been implicated in various human diseases, particularly cancer. In cancer, HuR is considered "active" when it shows increased subcellular localization in the cytoplasm, in addition to its normal nuclear localization. Cytoplasmic HuR plays a crucial role in stabilizing and enhancing the translation of prosurvival mRNAs that are involved in stress responses relevant to cancer progression, such as hypoxia, radiotherapy, and chemotherapy. In general, due to HuR's abundance and function in cancer cells compared with normal cells, it is an appealing target for oncology research. Exploiting the principles underlying HuR's role in tumorigenesis and resistance to stressors, targeting HuR has the potential for synergy with existing and novel oncologic therapies. This review aims to explore HuR's role in homeostasis and cancer pathophysiology, as well as current targeting strategies, which include silencing HuR expression, preventing its translocation and dimerization from the nucleus to the cytoplasm, and inhibiting mRNA binding. Furthermore, this review will discuss recent studies investigating the potential synergy between HuR inhibition and traditional chemotherapeutics.

Abstract
BACKGROUND Pancreatic adenocarcinoma (PDAC) often impinges on the biliary tree and obstruction necessitates stent placement increasing the risk of surgical site infections (SSIs). We sought to explore the impact of neoadjuvant therapy on the biliary microbiome and SSI risk in patients undergoing resection. METHODS A retrospective analysis was performed on 346 patients with PDAC who underwent resection at our institution from 2008 to 2021. Univariate and multivariate methods were utilized for analysis. RESULTS Biliary stenting rates were similar between groups but resulted in increased bile culture positivity (97% vs. 15%, p < 0.001). Culture positivity did not differ between upfront resection or neoadjuvant chemotherapy (NAC) (77% vs. 80%, p = 0.60). NAC-alone versus neoadjuvant chemoradiotherapy did not impact biliary positivity (80% vs. 79%, p = 0.91), nor did 5-fluorouracil versus gemcitabine-based regimens (73% vs. 85%, p = 0.19). While biliary stenting increased incisional SSI risk (odds ratios [OR]: 3.87, p = 0.001), NAC did not (OR: 0.83, p = 0.54). Upfront resection, NAC, and chemoradiotherapy were not associated with biliary organism-specific changes or antibiotic resistance patterns. CONCLUSIONS Biliary stenting is the greatest predictor for positive biliary cultures and SSIs in resected PDAC patients. Neither NAC nor radiotherapy impact bile culture positivity, speciation, rates, or antibiotic resistance patterns, and perioperative antibiotic prophylaxis should not differ.

Abstract
BACKGROUND AND OBJECTIVES Primary resection and debulking of liver metastases have been associated with improved survival in pancreatic neuroendocrine tumors (PNETs). The treatment patterns and outcomes differences between low-volume (LV) institutions and high-volume (HV) institutions remains unstudied. METHODS A statewide cancer registry was queried for patients with nonfunctional PNET from 1997 to 2018. LV institutions were defined as treating <5 newly diagnosed patients with PNET per year, while HV institutions treated ≥5. RESULTS We identified 647 patients: 393 with locoregional (n = 236 HV care, n = 157 LV care) and 254 with metastatic disease (n = 116 HV care, n = 138 LV care). Patients with HV care had improved disease-specific survival (DSS) compared to patients with LV care for both locoregional (median 63 vs. 32 months, p < 0.001) and metastatic disease (median 25 vs. 12 months, p < 0.001). In patients with metastatic disease, primary resection (hazard ratio [HR]: 0.55, p = 0.003) and HV institution (HR: 0.63, p = 0.002) were independently associated with improved DSS. Furthermore, diagnosis at a HV center was independently associated with higher odds of receiving primary site surgery (odds ratio [OR]: 2.59, p = 0.01) and metastasectomy (OR: 2.51, p = 0.03). CONCLUSIONS Care at HV centers is associated with improved DSS in PNET. We recommend referral of all patients with PNETs to HV centers.

Abstract
Importance Treatment at high-volume centers (HVCs) has been associated with improved overall survival (OS) in patients with pancreatic ductal adenocarcinoma (PDAC); however, it is unclear how patterns of referral affect these findings. Objective To understand the relative contributions of treatment site and selection bias in driving differences in outcomes in patients with PDAC and to characterize socioeconomic factors associated with referral to HVCs. Design, Setting, Participants A population-based retrospective review of the Oregon State Cancer Registry was performed from 1997 to 2019 with a median 4.3 months of follow-up. Study participants were all patients diagnosed with PDAC in Oregon from 1997 to 2018 (n = 8026). Exposures The primary exposures studied were diagnosis and treatment at HVCs (20 or more pancreatectomies for PDAC per year), low-volume centers ([LVCs] less than 20 per year), or both. Main Outcomes and Measures OS and treatment patterns (eg, receipt of chemotherapy and primary site surgery) were evaluated with Kaplan-Meier analysis and logistic regression, respectively. Results Eight thousand twenty-six patients (male, 4142 [52%]; mean age, 71 years) were identified (n = 3419 locoregional, n = 4607 metastatic). Patients receiving first-course treatment at a combination of HVCs and LVCs demonstrated improved median OS for locoregional and metastatic disease (16.6 [95% CI, 15.3-17.9] and 6.1 [95% CI, 4.9-7.3] months, respectively) vs patients receiving HVC only (11.5 [95% CI, 10.7-12.3] and 3.9 [95% CI, 3.5-4.3] months, respectively) or LVC-only treatment (8.2 [95% CI, 7.7-8.7] and 2.1 [95% CI, 1.9-2.3] months, respectively; all P < .001). No differences existed in disease burden by volume status of diagnosing institution. When stratifying by site of diagnosis, HVC-associated improvements in median OS were smaller (locoregional: 10.4 [95% CI, 9.5-11.2] vs 9.9 [95% CI, 9.4-10.4] months; P = .03; metastatic: 3.6 vs 2.7 months, P < .001) than when stratifying by the volume status of treating centers, indicating selection bias during referral. A total of 94% (n = 1103) of patients diagnosed at an HVC received HVC treatment vs 18% (n = 985) of LVC diagnoses. Among patients diagnosed at LVCs, later year of diagnosis and higher estimated income were independently associated with higher odds of subsequent HVC treatment, while older age, metastatic disease, and farther distance from HVC were independently associated with lower odds. Conclusions and Relevance LVC-to-HVC referrals for PDAC experienced improved OS vs HVC- or LVC-only care. While disease-related features prompting referral may partially account for this finding, socioeconomic and geographic disparities in referral worsen OS for disadvantaged patients. Measures to improve access to HVCs are encouraged.

Abstract
BACKGROUND Though telemedicine has been identified as safe and feasible, data on patient reported experiences (PREs) are lacking. We sought to compare PREs between in-person and telemedicine-based perioperative care. METHODS Patients evaluated from August-November 2021 were prospectively surveyed to assess experiences and satisfaction with care rendered during in-person and telemedicine-based encounters. Patient and hernia characteristics, encounter related plans, and PREs were compared between in-person and telemedicine-based care. RESULTS Of 109 respondents (86% response rate), 55% (n = 60) utilized telemedicine-based perioperative care. Indirect costs were lower for patients using telemedicine-based services, including work absence (3% vs. 33%, P < 0.001), lost wages (0% vs. 14%, P = 0.003), and requirements for hotel accommodations (0% vs. 12%, P = 0.007). PREs related to telemedicine-based care were non-inferior to in-person care across all measured domains (P > 0.4). CONCLUSIONS Telemedicine-based care yields significant cost-savings over in-person care with similar patient satisfaction. These findings suggest that systems should focus on optimization of perioperative telemedicine services.

Abstract
BACKGROUND In hormone receptor-positive breast cancer (HRPBC), endocrine therapy is often initiated after adjuvant radiotherapy given concerns of radiation fibrosis. No studies have investigated how this may impact outcomes in high-risk patients undergoing neoadjuvant chemotherapy (NAC). METHODS Females with nonmetastatic HRPBC receiving NAC from 2011 to 2017 were identified from our multi-institutional database. Interval from surgery to endocrine therapy (ISET) was calculated in weeks. Recurrence-free survival (RFS) and overall survival (OS) were evaluated with Kaplan-Meier and Cox proportional hazards modeling. RESULTS Of 280 patients, 179 (64%) received adjuvant radiotherapy; all deaths (n = 25) and 90% (n = 27) of recurrences occurred in this group, which was the focus of subsequent analysis. Median follow-up was 49 months. Recurrences were predominantly distant metastases (n = 21, 81%). Median ISET was 12 weeks (range 0-55 weeks). On multivariable analysis, ISET >14 weeks was independently associated with worse RFS (HR 3.20, 95% C.I. 1.22-8.40, P = 0.02) but not OS (HR 2.15, 95% C.I. 0.75-6.15, P = 0.15). CONCLUSION In patients with HRPBC treated with NAC and adjuvant radiation, increasing ISET is associated with adverse oncologic outcomes.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is often diagnosed at a locally advanced stage with vascular involvement which was previously viewed as a contraindication to resection. However, high-volume centers are increasingly capable of resecting complex tumors. We aimed to explore patterns of treatment that are uncharacterized on a population level. METHODS A statewide registry was queried from 2003 to 2018 for stage III PDAC. Stepwise logistic regression and Kaplan-Meier were used for statistical analysis. RESULTS We identified 424 eligible patients. 348 (82%) received chemotherapy, 17 (4.0%) received resection, and 59 (13.9%) received both; median survival was 10.7, 8.7, and 22.7 months, respectively (P < 0.001). High-volume centers (≥20 cases per year; OR 5.40 [95% CI: 2.76, 10.58], P < 0.001) and later year of diagnosis (OR 1.12/year [95% CI: 1.04, 1.20], P = 0.004) were associated with higher odds of receiving combined therapy. CONCLUSION PDAC patients with vascular involvement who receive both systemic chemotherapy and surgical resection have improved overall survival. High-volume centers are independently associated with higher odds of receiving combined systemic therapy and surgical resection.

Abstract
BACKGROUND Traditionally, surgical drains are considered a relative contraindication to telemedicine-based postoperative care. We sought to assess the safety, feasibility, and outcomes of an at-home patient-performed surgical drain removal pilot program. METHODS A prospective cohort study among patients who were discharged with surgical drains was performed. Patients discharged with drains were given the option for in-clinic, provider-performed removal, or at-home, patient-performed drain removal. Patient demographics, health characteristics, perioperative metrics, and operative outcomes were compared and analyzed. RESULTS A total of 68 encounters with drain removal were included (at-home: 28%, n = 19; in-clinic: 72%, n = 49), with both groups having similar demographics, except for age (median age of telemedicine-based at-home: 50 vs in-clinic: 62 years, p = 0.03). Patients who opted into at-home, patient-performed drain removal were more likely to have drain removal occur earlier (9 vs 13 days for in-clinic, p < 0.001). In-clinic removal resulted in increased encounters with surgical nursing staff and increased travel time, with no significant difference in complication burden. CONCLUSIONS Patient-performed at-home drain removal is safe and allows for more timely drain removal.

Abstract
INTRODUCTION Patients developing metastatic gastrointestinal stromal tumors (mGIST) have heterogenous disease biology and oncologic outcomes; prognostic factors are incompletely characterized. We sought to evaluate predictors of 10-year metastatic survivorship in the era of tyrosine kinase inhibitor (TKI) therapy. METHODS We reviewed patients with mGIST treated at our Comprehensive Cancer Center from 2003 to 2019, including only patients with either mortality or 10 years of follow-up. Ten-year survivorship was evaluated with logistic regression. RESULTS We identified 109 patients with a median age of 57 years at mGIST diagnosis. Synchronous disease was present in 57% (n = 62) of patients; liver (n = 48, 44%), peritoneum (n = 40, 37%), and liver + peritoneum (n = 18, 17%) were the most common sites. Forty-six (42%) patients were 10-year mGIST survivors. Following mGIST diagnosis, radiographic progression occurred within 2 years in 53% (n = 58) of patients, 2-5 years in 16% (n = 17), and 5-10 years in 16% (n = 17), with median survival of 32, 76, and 173 months, respectively. Seventeen (16%) patients had not progressed by 10 years. Fifty-two (47%) patients underwent metastasectomy, which was associated with improved progression-free survival (hazard ratio 0.63, p = 0.04). In patients experiencing progression, factors independently associated with 10-year survivorship were age (odds ratio [OR] 0.96, p = 0.03) and time to progression (OR 1.71/year, p < 0.001). CONCLUSIONS Ten-year survivorship is achievable in mGIST in the era of TKIs and is associated with younger age and longer time to first progression, while metastasectomy is associated with longer time to first progression. The role of metastasectomy in the management of patients with disease progression receiving TKI therapy merits further study.

Abstract
Background: Uveal melanoma is an aggressive cancer with high metastatic risk. Recently, we identified a circulating cancer cell population that co-expresses neoplastic and leukocyte antigens, termed circulating hybrid cells (CHCs). In other cancers, CHCs are more numerous and better predict oncologic outcomes compared to circulating tumor cells (CTCs). We sought to investigate the potential of CHCs as a prognostic biomarker in uveal melanoma. Methods: We isolated peripheral blood monocular cells from uveal melanoma patients at the time of primary treatment and used antibodies against leukocyte and melanoma markers to identify and enumerate CHCs and CTCs by immunocytochemistry. Results: Using a multi-marker approach to capture the heterogeneous disseminated tumor cell population, detection of CHCs was highly sensitive in uveal melanoma patients regardless of disease stage. CHCs were detected in 100% of stage I-III uveal melanoma patients (entire cohort, n = 68), whereas CTCs were detected in 58.8% of patients. CHCs were detected at levels statically higher than CTCs across all stages (p = 0.05). Moreover, CHC levels, but not CTCs, predicted 3 year progression-free survival (p < 0.03) and overall survival (p < 0.04). Conclusion: CHCs are a novel and promising prognostic biomarker in uveal melanoma.

Abstract
Simple Summary In cancer, disseminated neoplastic cells circulating in blood are a source of tumor DNA, RNA, and protein, which can be harnessed to diagnose, monitor, and better understand the biology of the tumor from which they are derived. Historically, circulating tumor cells (CTCs) have dominated this field of study. While CTCs are shed directly into circulation from a primary tumor, they remain relatively rare, particularly in early stages of disease, and thus are difficult to utilize as a reliable cancer biomarker. Neoplastic-immune hybrid cells represent a novel subpopulation of circulating cells that are more reliably attainable as compared to their CTC counterparts. Here, we review two recently identified circulating cell populations in cancer—cancer-associated macrophage-like cells and circulating hybrid cells—and discuss the future impact for the exciting area of disseminated hybrid cells. Abstract Cancer remains a significant cause of mortality in developed countries, due in part to difficulties in early detection, understanding disease biology, and assessing treatment response. If effectively harnessed, circulating biomarkers promise to fulfill these needs through non-invasive “liquid” biopsy. While tumors disseminate genetic material and cellular debris into circulation, identifying clinically relevant information from these analytes has proven difficult. In contrast, cell-based circulating biomarkers have multiple advantages, including a source for tumor DNA and protein, and as a cellular reflection of the evolving tumor. While circulating tumor cells (CTCs) have dominated the circulating cell biomarker field, their clinical utility beyond that of prognostication has remained elusive, due to their rarity. Recently, two novel populations of circulating tumor-immune hybrid cells in cancer have been characterized: cancer-associated macrophage-like cells (CAMLs) and circulating hybrid cells (CHCs). CAMLs are macrophage-like cells containing phagocytosed tumor material, while CHCs can result from cell fusion between cancer and immune cells and play a role in the metastatic cascade. Both are detected in higher numbers than CTCs in peripheral blood and demonstrate utility in prognostication and assessing treatment response. Additionally, both cell populations are heterogeneous in their genetic, transcriptomic, and proteomic signatures, and thus have the potential to inform on heterogeneity within tumors. Herein, we review the advances in this exciting field.

Abstract
BACKGROUND Sarcopenia is associated with complications and inferior oncologic outcomes in solid tumors. Axial computed tomography (CT) scans can be used to evaluate sarcopenia, however manual quantification is laborious. We sought to validate an automated method of quantifying muscle cross-sectional area (CSA) in patients with pancreatic adenocarcinoma (PDAC). METHODS Mid-L3 CT images from patients with PDAC were analyzed: CSAs of skeletal muscle (SM) were measured using manual segmentation and the software AutoMATiCA, and then compared with linear regression. RESULTS Five-hundred-twenty-five unique scans were analyzed. There was robust correlation between manual and automated segmentation for L3 CSA (R2 0.94, P < 0.001). Bland-Altman analysis demonstrated a consistent overestimation of muscle CSA by AutoMATiCA with a mean difference of 5.7%. A correction factor of 1.06 was validated using a unique test dataset of 36 patients with non-PDAC peripancreatic malignancies. CONCLUSIONS Automated muscle CSA measurement with AutoMATiCA is highly efficient and yields results highly correlated with manual measurement. These findings support the potential use of high-throughput sarcopenia analysis with abdominal CT scans for both clinical and research purposes.

Abstract
Yes-associated protein 1 (YAP1) is indispensable for the development of mutant KRAS-driven pancreatic ductal adenocarcinoma (PDAC). High YAP1 mRNA is a prognostic marker for worse overall survival in patient samples; however, the regulatory mechanisms that mediate its overexpression are not well understood. YAP1 genetic alterations are rare in PDAC, suggesting that its dysregulation is likely not due to genetic events. HuR is an RNA-binding protein whose inhibition impacts many cancer-associated pathways, including the "conserved YAP1 signature" as demonstrated by gene set enrichment analysis. Screening publicly available and internal ribonucleoprotein immunoprecipitation (RNP-IP) RNA sequencing (RNA-Seq) data sets, we discovered that YAP1 is a high-confidence target, which was validated in vitro with independent RNP-IPs and 3' untranslated region (UTR) binding assays. In accordance with our RNA sequencing analysis, transient inhibition (e.g., small interfering RNA [siRNA] and small-molecular inhibition) and CRISPR knockout of HuR significantly reduced expression of YAP1 and its transcriptional targets. We used these data to develop a HuR activity signature (HAS), in which high expression predicts significantly worse overall and disease-free survival in patient samples. Importantly, the signature strongly correlates with YAP1 mRNA expression. These findings highlight a novel mechanism of YAP1 regulation, which may explain how tumor cells maintain YAP1 mRNA expression at dynamic times during pancreatic tumorigenesis.

Abstract
INTRODUCTION Radical antegrade modular pancreatosplenectomy (RAMPS) was developed to improve R0 resections and lymph node harvests versus distal pancreatectomy (DP) in pancreatic adenocarcinoma (PDAC); relative complication rates are understudied. METHODS Patients undergoing distal pancreas resections from 2006 to 2020 were identified from our institutional NSQIP database, grouped by resection method, and evaluated for the following outcomes: postoperative pancreatic fistula (POPF), clinically relevant POPF (crPOPF), incisional surgical site infection (iSSI), organ space SSI (osSSI), and Clavien-Dindo grade ≥ 3 (CD ≥ 3) complications using logistic regression. Patients were matched 1:1 based on disease risk score. RESULTS Two-hundred-thirty-six and 117 patients underwent DP and RAMPS, respectively. POPF, crPOPF, CD ≥ 3 complications, iSSI, and osSSIs occurred in 105 (30%), 43 (12%), 74 (21%), 34 (10%) and 52 (15%) patients, respectively. Disease risk score matching yielded 89 similar patients per group. On multivariable analysis, patients undergoing RAMPS were not significantly more likely to experience POPF (OR 0.69, P = 0.26), crPOPF (OR 0.41, P = 0.72), CD ≥ 3 complication (OR 0.78, P = 0.44), iSSI (OR 0.58, P = 0.27), or osSSI (OR 0.93, P = 0.86). Of patients with PDAC (n = 108) mean nodal harvest were 14.8 (SD 11.30) and 19.4 (SD 7.19) nodes for patients undergoing DP and RAMPS, respectively (P = 0.01). Six patients (20%) undergoing DP had positive margins versus 12 (15%) undergoing RAMPS (P = 0.56). At a median follow-up of 17 months, there was no difference in locoregional recurrence-free survival (P = 0.32) or overall survival (P = 0.92) on Kaplan-Meier analysis. CONCLUSION RAMPS does not result in increased complications compared to DP and routine use is encouraged in pancreatic malignancies.

Abstract
BACKGROUND Perioperative telemedicine use has increased as a result of the COVID-19 pandemic and may improve access to surgical care. However, studies assessing outcomes in populations at risk for digital-health disparities are lacking. We sought to characterize the pre- and postoperative outcomes for rural patient populations being assessed for hernia repair and abdominal wall reconstruction with telehealth. METHODS Patients undergoing telehealth evaluation from March 2020 through May 2021 were identified. Rurality was identified by zip code of residence. Rural and urban patients were compared based on demographics, diagnosis, treatment plan, and visit characteristics and outcomes. Downstream care use related to supplementary in-person referral, and diagnostic testing was assessed. RESULTS Three hundred-seventy-three (196 preoperative, 177 postoperative) telehealth encounters occurred during the study period (rural: 28% of all encounters). Rural patients were more likely to present with recurrent or incisional hernias (90.0 vs 72.7%, p = 0.02) and advanced comorbidities (American Society of Anesthesiologists status score > 2: 73.1 vs 52.1%, p = 0.009). Rural patients derived significant benefits related to time saved commuting, with median distances of 299 and 293 km for pre- and postoperative encounters, respectively. Downstream care use was 6.1% (N = 23) for additional in-person evaluations and 3.4% (N = 13) for further diagnostic testing, with no difference by rurality. CONCLUSIONS Perioperative telehealth can safely be implemented for rural populations seeking hernia repair and may be an effective method for reducing disparities. Downstream care use related to additional in-person referral or diagnostic testing was minimally impacted in both the preoperative and postoperative settings. These findings suggest that rurality should not deter surgeons from providing telemedicine-based surgical consultation for hernia repair.

Abstract
BACKGROUND Screening for cancer-related psychosocial distress is an integral yet laborious component of quality oncologic care. Automated preappointment screening through online patient portals (Portal, MyChart) is efficient compared with paper-based screening, but unstudied. We hypothesized that patient access to and engagement with EHR-based screening would positively correlate with factors associated with digital literacy (eg, age, socioeconomic status). METHODS Screening-eligible oncology patients seen at our Comprehensive Cancer Center from 2014 through 2019 were identified. Patients with active Portals were offered distress screening. Portal and screening participation were analyzed via multivariable logistic regression. Household income in US dollars and educational attainment were estimated utilizing zip code and census data. RESULTS Of 17,982 patients, 10,279 (57%) had active Portals and were offered distress screening. On multivariable analysis, older age (odds ratio [OR], 0.97/year; P<.001); male gender (OR, 0.89; P<.001); Black (OR, 0.47; P<.001), Hawaiian/Pacific Islander (OR, 1.54; P=.007), and Native American/Alaskan Native race (OR, 0.67; P=.04); Hispanic ethnicity (OR, 0.76; P<.001); and Medicare (OR, 0.59; P<.001), Veteran's Affairs/military (OR, 0.09; P<.01), Medicaid (OR, 0.34; P<.001), or no insurance coverage (OR, 0.57; P<.001) were independently associated with lower odds of being offered distress screening; increasing income (OR, 1.05/$10,000; P<.001) and educational attainment (OR, 1.03/percent likelihood of bachelor's degree or higher; P<.001) were independently associated with higher odds. In patients offered electronic screening, participation rate was 36.6% (n=3,758). Higher educational attainment (OR, 1.01; P=.03) was independently associated with participation, whereas Black race (OR, 0.58; P=.004), Hispanic ethnicity (OR, 0.68; P=.01), non-English primary language (OR, 0.67; P=.03), and Medicaid insurance (OR, 0.78; P<.001) were independently associated with nonparticipation. CONCLUSIONS Electronic portal-based screening for cancer-related psychosocial distress leads to underscreening of vulnerable populations. At institutions using electronic distress screening workflows, supplemental screening for patients unable or unwilling to engage with electronic screening is recommended to ensure efficient yet equal-opportunity distress screening.

Abstract
BACKGROUND Tyrosine kinase inhibitor (TKI) neoadjuvant therapy (NAT) is often given in gastrointestinal stromal tumors (GISTs) with the goal to facilitate less morbid resections and improve oncologic outcomes; however, the use of NAT for GIST is poorly studied. METHODS We reviewed patients with resected nonmetastatic GIST from 2003 to 2019. Overall (OS) and recurrence-free survival (RFS) were assessed with Kaplan-Meier modeling. We performed 1:1 propensity-matching for relevant clinicopathologic variables for receipt of NAT. RESULTS We identified 254 patients. Propensity 1:1 matching resulted in 33 patients per group. The median follow-up was 77 months with no difference in 10-year OS (68% vs. 73%), 5-year RFS (13% vs. 10%), or median RFS (24 vs. 27 months) for patients treated with NAT versus upfront resection (all P > 0.9). Hospital length-of-stay (both median 7 days) and Clavien-Dindo ≥ III complications (12% vs. 3%) were not different between groups (both P ≥ 0.35). DISCUSSION TKI NAT can be used to facilitate resection in select patients with surgically higher-risk GIST, however it does not result in an independent oncologic benefit.

Abstract
BACKGROUND Hepatic resection for metastatic GIST (mGIST) is often performed with either curative-intent or for tyrosine kinase inhibitor (TKI)-resistant lesions. The efficacy of hepatectomy for treatment-resistant lesions (TRL) is uncertain. METHODS We reviewed patients with liver-mGIST treated from 2003 to 2018. Oncologic outcomes including overall (OS), post-operative progression-free survival (PFS), and post-progression OS were evaluated using Kaplan-Meier and Cox proportional hazards modeling. RESULTS We identified n = 91 patients; 31 (34%) underwent curative-intent hepatectomy, 60 (66%) were initially managed with TKI alone, and 17 (19%) had resection of a TRL. The median follow-up for resected patients was 102 months (range 5-209 months) with 23 (25%) managed with a major hepatectomy. Patients having curative-intent hepatectomy had 72% 10-year OS following diagnosis of liver-mGIST, compared with 58% (P = 0.50) for TRL resection and 41% (P = 0.01) for non-resected patients. Curative-intent hepatectomy (HR 0.39, P = 0.03) and age (HR 1.04, P = 0.004) were independently associated with 10-year OS, but not TRL resection. TRL resection was not associated with improved post-progression OS compared to second-line TKI therapy (HR 0.61, P = 0.21). CONCLUSIONS Curative-intent hepatectomy is associated with improved OS in liver-mGIST. The oncologic benefit of resecting treatment-resistant liver-mGIST compared to second-line TKI therapy alone remains unclear in the era of multi-line TKI therapy.

Abstract
BACKGROUND AND OBJECTIVES Colorectal liver metastasis (CRLM) is a leading cause of morbidity and mortality in patients with colorectal cancer. Hepatic arterial infusion (HAI) chemotherapy has been demonstrated to improve survival in patients with resected CRLM and to facilitate conversion of technically unresectable disease. METHODS Between 2016 and 2018, n = 22 HAI pumps were placed for CRLM. All patients received systemic chemotherapy concurrently with HAI floxuridine/dexamethasone. Overall survival (OS) and progression-free survival (PFS) were assessed using the Kaplan-Meier method. RESULTS HAI pumps were placed in seven patients with completely resected CRLM and 15 patients with unresectable disease. Twenty-one patients received HAI floxuridine with a median of 5 total HAI cycles (interquartile range: 4-7). Biliary sclerosis was the most common HAI-related complication (n = 5, 24%). Of the 13 patients treated to convert unresectable CRLM, 3 (23%) underwent hepatic resection with curative intent after a median of 7 HAI cycles (range: 4-10). For all HAI patients, the mean OS was 26.7 months from CRLM diagnosis, while the median PFS and hepatic PFS from pump placement were 9 and 13 months, respectively. CONCLUSION Concomitant HAI and systemic therapy can be utilized at multidisciplinary programs for patients with advanced CRLM, both in the adjuvant setting and to facilitate conversion of unresectable disease.

Abstract
Disparities in pancreatic cancer incidence and outcomes exist in Native American populations. These disparities are multifactorial, difficult to quantify, and are influenced by historical, socioeconomic, and health care structural factors. The objective of this article was to assess these factors and offer a call to action to overcome them. The authors reviewed published data on pancreatic cancer in Native American populations with a focus on disparities in incidence, outcomes, and research efforts. The historical context of the interactions between Native Americans and the United States health care system was also analyzed to form actionable items to build trust and collaboration. The incidence of pancreatic cancer in Native Americans is higher than that in the general US population and has the worst survival of any major racial or ethnic group. These outcomes are influenced by a patient population with often poor access to high-quality cancer care, historical trauma potentially leading to reduced care utilization, and a lack of research focused on etiologies and comorbid conditions that contribute to these disparities. A collaborative effort between nontribal and tribal leaders and cancer centers is key to addressing disparities in pancreatic cancer outcomes and research. More population-level studies are needed to better understand the incidence, etiologies, and comorbid conditions of pancreatic cancer in Native Americans. Finally, a concerted, focused effort should be undertaken between nontribal and tribal entities to increase the access of Native Americans to high-quality care for pancreatic cancer and other lethal malignancies.

Abstract
INTRODUCTION Many postoperative acute care visits (PACVs) are likely more appropriately addressed in lower acuity settings; however, the frequency and nature of PACVs are not currently tracked by the National Surgical Quality Improvement Program (NSQIP), and the overall burden to emergency departments and urgent care centers is unknown. METHODS NSQIP collaborative data were augmented to prospectively capture 30-d PACVs for 1 y starting October 2018 across all NSQIP specialties, including visit reason and disposition. Data were analyzed using binomial logistic regression. RESULTS A total of 9933 patients were identified; 12.0% (n = 1193) presented to an acute care setting over 1413 visits, most commonly for surgical pain (15.4%) in the absence of an identified complication. Visits most commonly resulted in discharge (n = 817, 68.5%) or admission (n = 343, 24.3%). Variables independently associated with visits resulting in discharge included age (odds ratio [OR] 0.99 per year, P < 0.001), increasing comorbidities (1-2 [OR 1.55, P < 0.001]; 3-4 [OR 2.51, P < 0.001]; 5+ [OR 2.79 P < 0.001]), operative duration (OR 1.08 per hour, P = 0.001), and nonelective (OR 1.20, P = 0.01) or urologic (OR 1.46, P = 0.01) procedures. CONCLUSIONS PACVs are an overlooked burden on emergency medicine providers and healthcare systems; most do not require admission and could be potentially triaged outside of the acute care setting with improved perioperative care infrastructure. Younger patients, those with multiple comorbidities, and those undergoing nonelective procedures deserve special attention when designing initiatives to address postoperative acute care utilization. Data regarding PACVs can be routinely collected with minor modifications to current NSQIP workflows.

Abstract
In pancreatic neuroendocrine tumors (PNETs), the impact of minimally invasive (MI) versus open resection on outcomes remains poorly studied. We queried a multi-institutional pancreatic cancer registry for patients with resected non-metastatic PNET from 1996−2020. Recurrence-free (RFS), disease-specific survival (DSS), and operative complications were evaluated. Two hundred and eighty-two patients were identified. Operations were open in 139 (49%) and MI in 143 (51%). Pancreaticoduodenectomy was performed in 77 (27%, n = 23 MI), distal pancreatectomy in 184 (65%, n = 109 MI), enucleation in 13 (5%), and total pancreatectomy in eight (3%). Median follow-up was 50 months. Thirty-six recurrences and 13 deaths from recurrent disease yielded 5-year RFS and DSS of 85% and 95%, respectively. On multivariable analysis, grade 1 (HR 0.07, p < 0.001) and grade 2 (HR 0.20, p = 0.002) tumors were associated with improved RFS, while T3/T4 tumors were associated with worse RFS (OR 2.78, p = 0.04). MI resection was not associated with RFS (HR 0.53, p = 0.14). There was insufficient mortality to evaluate DSS with multivariable analysis. Of 159 patients with available NSQIP data, incisional surgical site infections (SSIs), organ space SSIs, Grade B/C pancreatic fistulas, reoperations, and need for percutaneous drainage did not differ by operative approach (all p > 0.2). Nodal harvest was similar for MI versus open distal pancreatectomies (p = 0.16) and pancreaticoduodenectomies (p = 0.28). Minimally invasive surgical management of PNETs is equivalent for oncologic and postoperative outcomes.

Abstract
BACKGROUND Intraoperative autologous transfusion (IAT) of salvaged blood is a common method of resuscitation during liver transplantation (LT), however concern for recurrence in recipients with hepatocellular carcinoma (HCC) has limited widespread adoption. METHODS A review of patients undergoing LT for HCC between 2008 and 2018 was performed. Clinicopathologic and intraoperative characteristics associated with inferior recurrence-free (RFS) and overall survival (OS) were identified using Kaplan-Meier analysis and uni-/multi-variable Cox proportional hazards modeling. Propensity matching was utilized to derive clinicopathologically similar groups for subgroup analysis. RESULTS One-hundred-eighty-six patients were identified with a median follow up of 65 months. Transplant recipients receiving IAT (n = 131, 70%) also had higher allogenic transfusions (median 5 versus 0 units, P < 0.001). There were 14 recurrences and 46 deaths, yielding an estimated 10-year RFS and OS of 89% and 67%, respectively. IAT was not associated with RFS (HR 0.89/liter, P = 0.60), or OS (HR 0.98/liter, P = 0.83) pre-matching, or with RFS (HR 0.97/liter, P = 0.92) or OS (HR 1.04/liter, P = 0.77) in the matched cohort (n = 49 per group). CONCLUSION IAT during LT for HCC is not associated with adverse oncologic outcomes. Use of IAT should be encouraged to minimize the volume of allogenic transfusion in patients undergoing LT for HCC.

Abstract
INTRODUCTION Preoperative chemotherapy (POC) is often employed for patients with resectable colorectal liver metastasis (CRLM). The time to resection (TTR) following the end of chemotherapy may impact oncologic outcomes; this phenomenon has not been studied in CRLM. METHODS We queried our institutional cancer database for patients with resected CRLM after POC from 2003 to 2019. TTR was calculated from date of last cytotoxic chemotherapy. Kaplan-Meier analysis and multivariable Cox proportional hazards modeling were used to analyze recurrence-free survival (RFS) and overall survival (OS). RESULTS We identified n = 187 patients. One hundred twenty-four (66%) patients had a TTR of <2 months, while 63 (33%) had a TTR of ≥2 months. Median follow-up was 36 months. On Kaplan-Meier analysis, patients with TTR ≥ 2 months had shorter RFS (median 11 vs. 17 months, p = 0.002) and OS (median 44 vs. 62 months, p < 0.001). On multivariable analysis, TTR ≥ 2 months was independently associated with worse RFS (hazard ratio [HR] = 1.54, 95% confidence interval [CI] = 1.06-2.22, p = 0.02) and OS (HR = 1.75, 95% CI = 1.11-2.77, p = 0.01). CONCLUSION TTR ≥ 2 months following POC is independently associated with worse oncologic outcomes in patients with resectable CRLM. We therefore recommend consideration for hepatic resection of CRLM within this window whenever feasible.

Abstract
PURPOSE Screening for cancer-related psychosocial distress is recommended for patients with cancer; however, data on the long-term prevalence of distress and its natural history in survivors are scarce, preventing recommendations for screening frequency and duration. We sought to evaluate longitudinal distress in cancer patients. METHODS We evaluated longitudinal distress screening data for patients with cancer treated or surveilled at our institution from 2010 to 2018. Anxiety, depression, insurance/financial, family, memory, and strength-related distress were separately assessed and analyzed. Multivariable logistic regression was utilized to evaluate factors associated with distress subtypes. RESULTS In 5660 patients, distress was the highest at diagnosis for anxiety, depression, financial, and overall distress. On multivariable analysis, factors independently associated with distress at diagnosis included younger age, female gender, disease site/stage, payor, and income, varying by subtype-specific analyses. Severe distress in at least one subtype persisted in over 30% of survivors surveyed through 10 years after diagnosis. Over half of patients with initially severe distress at diagnosis improved within 12 months; however, distress worsened in 20-30% of patients with moderate, low, and no initial distress, regardless of the distress subtype. CONCLUSION Psychosocial distress in cancer survivors is a long-lasting burden with implications for quality of life and oncologic outcomes. Severe distress remains prevalent through 10 years after diagnosis in survivors receiving continued care at cancer centers and results from both persistent and new sources of distress in a variety of psychosocial domains. Longitudinal distress screening is an invaluable tool for providing comprehensive patient-centered cancer care and is recommended to detect new or recurrent distress in cancer survivors.

Abstract
BACKGROUND The definition of early recurrence (ER) in rectal cancer is unclear, and the association of ER with post-recurrence survival (PRS) is poorly described. We therefore sought to identify if time to recurrence (TTR) is associated with PRS. METHODS We reviewed all curative-intent resections of nonmetastatic rectal cancer from 2003 to 2018 in our institutional registry within an NCI-Designated Comprehensive Cancer Center. Clinicopathologic data at diagnosis and first recurrence were collected and analyzed. ER was pre-specified at < 24 months and late recurrence (LR) at ≥ 24 months. PRS was evaluated by the Kaplan-Meier method and Cox proportional hazards modeling. RESULTS At a median follow-up of 53 months, 61 out of 548 (11.1%) patients undergoing resection experienced recurrence. Median TTR was 14 months (IQR 10-18) with 45 of 61 patients (74%) classified as ER. There were no significant baseline differences between patients with ER and LR. Most recurrences were isolated to the liver (26%) or lung (31%), and 16% were locoregional. ER was not associated with worse PRS compared to LR (P > 0.99). On multivariable analysis, detection of recurrence via workup for symptoms, CEA > 10 ng/mL at recurrence, and site of recurrence were independently associated with PRS. CONCLUSION ER is not associated with PRS in patients with resected rectal cancer. Symptomatic recurrences and those accompanied by CEA elevations are associated with worse PRS, while metastatic disease confined to the liver or lung is associated with improved PRS. Attention should be directed away from TTR and instead toward determining therapy for patients with treatable oligometastatic disease.

Abstract
Metastatic pancreatic adenocarcinoma (PDAC) is a rapidly lethal disease, with less than half of patients surviving 12 months, and 5-year survival approximately 3%. These outcomes are in large part due to a lack of effective medical and surgical therapies for metastatic PDAC. Herein, we present the case of a patient with oligometastatic liver recurrence of BRCA2-mutated PDAC following a curative-intent resection. Through a combination of systemic chemotherapy, metastasectomy, radiotherapy, and subsequent targeted therapy with olaparib, the patient is asymptomatic four years following metastatic diagnosis with stable low-volume disease. This patient's excellent outcome is attributable to the multi-disciplinary care received, all aspects of which were informed by new evidence surrounding metastasectomy for metastatic PDAC, the unique biology and medical treatment of BRCA-mutated PDAC, and the role of radiotherapy in controlling locoregional recurrence. We provide a review of this evidence, while highlighting the importance of evaluating disease biology through somatic and germline genetic testing as well as monitoring response to systemic chemotherapy.

Abstract
BACKGROUND Multiple tumor foci (MTF) in intrahepatic cholangiocarcinoma (ICC), including satellitosis and true multifocality, is a known negative prognostic factor and can inform pre-operative decision-making. Lack of standardized pre-operative liver staging practices may contribute to undiagnosed MTF and poor outcomes. We sought to investigate the sensitivity of different cross-sectional imaging modalities for MTF at our institution. METHODS We identified n = 52 patients with ICC who underwent curative-intent resection from 2004 to 2017 in a multidisciplinary hepato-pancreato-biliary cancer program. Timing and modality of pre-operative imaging were recorded. Blinded review of imaging was performed and modalities were evaluated for false-negative rate (FNR) in detecting MTF, satellitosis, and true multifocality. RESULTS Forty-one (79%) patients underwent CT and 20 (38%) underwent MRI prior to hepatectomy. MTF was pre-operatively identified in six (12%) patients. An additional seven patients had MTF discovered on final surgical pathology, despite a median interval from CT/MRI to surgery of 20 days. On blinded review the FNR of MRI compared to CT for multifocality was 0% vs. 38%, 50% vs 80% for satellitosis, and 22% vs 46% for MTF as a whole. CONCLUSION CT is inadequate for pre-operative diagnosis of MTF in resectable ICC, even when performed within 30 days of hepatectomy. We recommend liver-protocol MRI as the standard pre-operative imaging modality in non-metastatic ICC.

Abstract
BACKGROUND Intrahepatic cholangiocarcinoma (ICC) is a rare cancer. Patients in rural areas may face reduced access to advanced treatments often only available at referral centers. We evaluated the association of referral center treatment with treatment patterns, outcomes, and geography in patients with ICC. METHODS We queried the Oregon State Cancer Registry for ICC between 1997 and 2016, collecting clinicopathologic, demographic, and oncologic data. Patients were classified by treatment at a referral center or non-referral center. 'Crowfly' distance to the nearest referral center (DRC) was calculated. Outcomes were evaluated using Kaplan-Meier, Cox proportional hazards modeling, and logistic regression. RESULTS Over 20 years, 740 patients with ICC had a median age of 66 years. Slightly more than half (n = 424, 57%) were non-referral center treated and 316 (43%) were referral center treated. Referral center treatment increased over time (odds ratio [OR] 1.03/year, p < 0.05). Referral center-treated patients had improved overall survival in all patients (median 9 vs. 4 months, p < 0.001), in the non-metastatic group (median 13 vs. 6 months, p < 0.001), and in patients not receiving liver resection (median 6 vs. 3 months, p < 0.05). On multivariable analysis, referral center-treated patients more often underwent chemotherapy, resection, or radiation (all p < 0.05). Increasing DRC (OR 0.98/20 km, p < 0.05) was independently associated with non-referral center treatment. CONCLUSION Patients with ICC who are evaluated at a referral center are more likely to receive treatments associated with better oncologic outcomes, including patients who are not managed with hepatic resection. Increasing the DRC is associated with treatment at a non-referral center; interventions to facilitate referral, such as telemedicine, may lead to improved outcomes for patients with ICC in rural states.

Abstract
BACKGROUND Patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer are treated with trastuzumab-based neoadjuvant therapy (NAT); some patients with residual disease post-NAT show loss of HER2 amplification and has been inconsistently associated with oncologic outcomes. METHODS We queried our multi-institutional cancer registry for women with HER2-positive breast cancer undergoing NAT from 2011 to 2018. Clinicopathologic, treatment-related, and outcomes data were collected. Kaplan-Meier and Cox proportional hazards analysis were used to evaluate oncologic outcomes. RESULTS A total of 348 patients were identified; 166 (48%) had a pathologic complete response. Of the 182 patients with residual disease, 87 (48%) were HER2-positive, 34 (19%) were HER2-negative, and 61 (33%) were HER2-unknown, with a median follow-up of 44 months. There were no factors associated with HER2 loss apart from age. On Kaplan-Meier analysis, estimated 5-year recurrence-free survival (RFS) and overall survival (OS) for patients with HER2-positive residual disease was 81% and 92%, respectively, and 74% (log rank p = 0.75) and 81% (p = 0.35) in patients with HER2-negative residual disease. CONCLUSION The loss of HER2-positivity following NAT is not associated with worse 5-year RFS or OS. We do not recommend retesting HER2 status following NAT for the purpose of clinical management; these patients should complete targeted adjuvant therapy.

Abstract
BACKGROUND Real-time monitoring of treatment response with a liquid biomarker has potential to inform treatment decisions for patients with rectal adenocarcinoma (RAC), esophageal adenocarcinoma (EAC), and colorectal liver metastasis (CRLM). Circulating hybrid cells (CHCs), which have both immune and tumor cell phenotypes, are detectable in the peripheral blood of patients with gastrointestinal cancers, but their potential as an indicator of treatment response is unexplored. METHODS Peripheral blood specimens were collected from RAC and EAC patients after neoadjuvant therapy (NAT) or longitudinally during therapy and evaluated for CHC levels by immunostaining. Receiver operating characteristics (ROCs) and the Kaplan-Meier method were used to analyze the CHC level as a predictor of pathologic response to NAT and disease-specific survival (DSS), respectively. RESULTS Patients with RAC (n = 23) and EAC (n = 34) were sampled on the day of resection, and 11 patients (32%) demonstrated a pathologic complete response (pCR) to NAT. On ROC analysis, CHC levels successfully discriminated pCR from non-pCR with an area under the curve of 0.82 (95% confidence interval [CI], 0.71-0.92; P < 0.001). Additionally, CHC levels in the EAC patients correlated with residual nodal involvement (P = 0.026) and 1-year DSS (P = 0.029). The patients with RAC who were followed longitudinally during NAT (n = 2) and hepatic arterial infusion therapy for CRLM (n = 2) had CHC levels that decreased with therapy response and increased before clinical evidence of disease progression. CONCLUSION Circulating hybrid cells are a novel blood-based biomarker with potential for monitoring treatment response and disease progression to help guide decisions for further systemic therapy, definitive resection, and post-therapy surveillance. Additional validation studies of CHCs are warranted.

Abstract
PURPOSE Gastrointestinal stromal tumors (GIST) commonly arise in different regions of the stomach and are driven by various mutations (most often in KIT, PDGFRA, and SDHx). We hypothesized that the anatomic location of gastric GIST is associated with unique genomic profiles and distinct driver mutations. EXPERIMENTAL DESIGN We compared KIT versus non-KIT status with tumor location within the National Cancer Database (NCDB) for 2,418 patients with primary gastric GIST. Additionally, we compiled an international cohort (TransAtlantic GIST Collaborative, TAGC) of 236 patients and reviewed sequencing results, cross-sectional imaging, and operative reports. Subgroup analyses were performed for tumors located proximally versus distally. Risk factors for KIT versus non-KIT tumors were identified using multivariate regression analysis. A random forest machine learning model was then developed to determine feature importance. RESULTS Within the NCDB cohort, non-KIT mutants dominated distal tumor locations (P < 0.03). Proximal GIST were almost exclusively KIT mutant (96%) in the TAGC cohort, whereas 100% of PDGFRA and SDH-mutant GIST occurred in the distal stomach. On multivariate regression analysis, tumor location was associated with KIT versus non-KIT mutations. Using random forest machine learning analysis, stomach location was the most important feature for predicting mutation status. CONCLUSIONS We provide the first evidence that the mutational landscape of gastric GIST is related to tumor location. Proximal gastric GIST are overwhelmingly KIT mutant, irrespective of morphology or age, whereas distal tumors display non-KIT genomic diversity. Anatomic location of gastric GIST may therefore provide immediate guidance for clinical treatment decisions and selective confirmatory genomic testing when resources are limited.

Abstract
Metastatic progression defines the final stages of tumor evolution and underlies the majority of cancer-related deaths. The heterogeneity in disseminated tumor cell populations capable of seeding and growing in distant organ sites contributes to the development of treatment resistant disease. We recently reported the identification of a novel tumor-derived cell population, circulating hybrid cells (CHCs), harboring attributes from both macrophages and neoplastic cells, including functional characteristics important to metastatic spread. These disseminated hybrids outnumber conventionally defined circulating tumor cells (CTCs) in cancer patients. It is unknown if CHCs represent a generalized cancer mechanism for cell dissemination, or if this population is relevant to the metastatic cascade. Herein, we detect CHCs in the peripheral blood of patients with cancer in myriad disease sites encompassing epithelial and non-epithelial malignancies. Further, we demonstrate that in vivo-derived hybrid cells harbor tumor-initiating capacity in murine cancer models and that CHCs from human breast cancer patients express stem cell antigens, features consistent with the potential to seed and grow at metastatic sites. Finally, we reveal heterogeneity of CHC phenotypes reflect key tumor features, including oncogenic mutations and functional protein expression. Importantly, this novel population of disseminated neoplastic cells opens a new area in cancer biology and renewed opportunity for battling metastatic disease.

Abstract
BACKGROUND Gallbladder cancer (GBC) is often incidentally diagnosed after cholecystectomy. Intra-operative biliary tract violations (BTV) have been recently associated with development of peritoneal disease (PD). The degree of BTV may be associated with PD risk, but has not been previously investigated. METHODS We reviewed patients with initially non-metastatic GBC treated at our institution from 2003 to 2018. Patients were grouped based on degree of BTV during their treatment: major (e.g., cholecystotomy with bile spillage, n = 27, 29%), minor (e.g., intra-operative cholangiogram, n = 18, 19%), and no violations (n = 48, 55%). Overall survival (OS) and peritoneal disease-free survival (PDFS) were evaluated with Kaplan-Meier and Cox proportional hazards modeling. RESULTS Ninety-three patients were identified; the median age was 64 years (range 31-87 years). Seventy-six (82%) were incidentally diagnosed. The median follow-up was 23 months; 20 (22%) patients developed PD. The 3-year PDFS for patients with major, minor, and no BTV was 52%, 83%, and 98%, respectively (major vs. none: p < 0.001; minor vs. none: p < 0.01). BTV was not associated with 5-year OS (HR 1.53, p = 0.16). CONCLUSION Increasing degree of BTV is associated with higher risk of peritoneal carcinomatosis in patients with GBC and should be considered during preoperative risk stratification. Reporting biliary tract violations during cholecystectomy is encouraged.

Abstract
BACKGROUND Gastrointestinal stromal tumors (GIST) commonly recur following curative-intent resection. Patients with recurrent GIST display heterogeneous outcomes with limited prognostic tools. We investigated factors associated with post-recurrence survival (PRS) and progression-free survival (PFS). METHODS We performed a review of our institutional cancer registry from 2003 to 2018 for patients with GIST. Clinicopathologic and outcome data were collected. The disease-free interval (DFI) was calculated from the end of curative-intent oncologic therapy until recurrence. Outcomes were evaluated using Kaplan-Meier and Cox proportional hazards modeling. RESULTS Overall, 254 patients underwent resection of primary, non-metastatic GIST, with 81 (32%) recurrences. The median age was 58 years and more than half of the patients with recurrence (n = 44; 54%) received adjuvant imatinib. Recurrence was most common in the liver (n = 34, 42%), peritoneum (n = 31, 38%), or liver plus peritoneum (n = 10, 12%). The median DFI was 14 months (interquartile range 2-26 months); 51 (63%) patients had a DFI ≤24 months and 30 (37%) had a DFI > 24 months. The median post-recurrence follow-up was 46 months. Compared with a DFI ≤24 months, patients with a DFI >24 months had increased 10-year PRS (77% vs. 41%, p < 0.05) and 10-year PFS (73% vs. 19%, p < 0.001). On multivariable analysis controlling for mutational and clinicopathologic features, a DFI >24 months was independently associated with increased PRS (hazard ratio [HR] 0.24, p < 0.01) and PFS (HR 0.18, p < 0.001). CONCLUSIONS The DFI is independently associated with oncologic outcomes in recurrent GIST and may be useful in treatment planning. Recurrence after 24 months may signify indolent disease biology that may benefit from additional treatment, including metastasectomy.

Abstract
BACKGROUND Levels of circulating hybrid cells (CHCs), a newly identified circulating tumor cell (CTC), correlate with disease stage and progression in cancer. We investigated their utility to risk-stratify patients with clinically N0 (cN0) oral cavity squamous cell carcinoma (OCSCC), and to identify patients with occult cervical lymph node metastases (pN+). METHODS We analyzed peripheral blood samples for CHCs with co-expression of cytokeratin (tumor) and CD45 (leukocyte) from 22 patients with cN0 OCSCC using immunofluorescence microscopy, then correlated levels with pathologic lymph node status. RESULTS CHC levels exceeded CTCs and correlated with the presence of both clinically overt (p = 0.002) and occult nodal metastases (p = 0.006). CONCLUSIONS For evaluated cN0 OCSCC patients, those with cN0 → pN+ status harbored elevated CHC levels compared to patients without occult disease. Our findings highlight a promising blood-based biologic assay with potential utility to determine the necessity of surgical neck dissection for staging and treatment.
