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 Resected colorectal liver metastases (CRLM) frequently recur intrahepatically. Selection criteria for repeat hepatectomy of recurrent CRLM are ill-defined. METHODS We performed an institutional review of patients with recurrent CRLM undergoing repeat hepatectomy from 2003 to 19. Post-recurrence overall (rOS) and recurrence-free survival (RFS) were analyzed with Cox proportional hazards modeling. RESULTS n = 147 experienced recurrent CRLM; 11% (n = 38) received repeat hepatectomy of which there was one Clavien-Dindo IIIa complication. Median rOS was 41 months; median RFS was 9 months. Improved rOS and RFS were independently associated with additional post-operative chemotherapy after repeat hepatectomy (HR 0.35 and 0.34, respectively); poor rOS with recurrent CRLM >3 cm (HR 4.4) and <12 months from first hepatectomy to recurrence (HR 4.8); poor RFS with ≥3 recurrence liver metastases (HR 2.8) (All P < 0.05). DISCUSSION Repeat hepatectomy for recurrent CRLM can be performed safely. Worse survival following repeat hepatectomy is independently associated with >3 cm and ≥3 liver lesions at recurrence, and <12 months to recurrence. Additional post-operative chemotherapy after repeat hepatectomy is associated with improved outcomes.

Abstract
INTRODUCTION Variant hepatic arterial anatomy (vHAA) is thought to occur in 20-30% of patients. Hepatic arterial infusion (HAI) pump placement for liver cancers requires thorough hepatic artery dissection; we sought to compare vHAA identified during pump placement with established dogma. METHODS Between 2016 and 2020, n = 30 patients received a HAI pump. Intra-operatively identified vHAA was characterized and compared with published data. RESULTS vHAA was identified in 60% (n = 18) of patients, significantly higher than 19% (3671 of 19013) in the largest published series (P < 0.001). The most common variations were accessory left (n = 12; 40%) and replaced right (n = 6; 20%) hepatic arteries; six (20%) had ≥2 variants. Pre-operative imaging correctly identified 67% of variant hepatic arteries. DISCUSSION Meticulous operative dissection of the hepatic arterial tree reveals vHAA not captured by imaging or cadaveric dissection. vHAA likely has a higher prevalence than previously reported and should be addressed to optimize therapeutic efficacy of HAI pump therapy.

Abstract
BACKGROUND The impact of neoadjuvant chemotherapy (NAC) on overall and recurrence-free survival (OS, RFS) in resectable intrahepatic cholangiocarcinoma (ICC) is poorly characterized. We sought to investigate the association of NAC with oncologic outcomes in ICC. METHODS We identified n = 52 patients with ICC undergoing hepatectomy from 2004 to 2017. Oncologic outcomes were analyzed using Kaplan-Meier and multivariate Cox proportional hazard modeling. RESULTS The median patient age was 64-years. NAC was administered in ten (19%) patients, most commonly with gemcitabine-cisplatin (n = 8, 80%). Median RFS and OS were 15 months. and 49 months, respectively. Controlling for stage and margins, NAC was independently associated with improved OS (HR 0.16, P = 0.01) but not RFS (HR 0.54, P = 0.27). NAC was not associated with major post-operative complications (P = 0.25) or R1 margins (P = 0.58). CONCLUSION NAC in ICC may hold oncologic benefits beyond downstaging borderline resectable disease, such as identifying patients with favorable biology who are more likely to benefit from resection.

Abstract
Superior mesenteric artery (SMA) syndrome is an uncommon phenomenon caused by the compression of the third portion of the duodenum between the aorta and the SMA. Here, we present a previously healthy 15-year-old male who presented with early satiety and 20 kg weight loss. Computed tomography (CT) demonstrated a massive retroperitoneal liposarcoma displacing the entire small intestine into the right upper quadrant. Following resection of the large mass, the patient was intolerant of oral intake despite evidence of bowel function. Abdominal CT revealed a narrowing of the duodenum at the location of the SMA. A nasojejunal feeding tube was placed past this area, and enteral nutrition was initiated before slowly resuming oral intake. Post-operative SMA syndrome is an uncommon complication but should be considered in patients intolerant of oral intake following resection of large abdominal tumors associated with extensive retroperitoneal fat loss, even in the absence of concomitant major visceral resection.

Abstract
INTRODUCTION Hepatic artery infusion pump (HAIP) chemotherapy is a specialized therapy for patients with unresectable colorectal liver metastases (uCRLM). Its effectiveness was demonstrated from a high volume center, with uncertainty regarding the feasibility and safety at other centers. Therefore, we sought to assess the safety and feasibility of HAIP for the management of uCRLM at other centers. METHODS We conducted a multicenter retrospective cohort study of patients with uCRLM treated with HAIP from January 2003 to December 2017 at six North American centers initiating the HAIP program. Outcomes included the safety and feasibility of HAIP chemotherapy. RESULTS We identified 154 patients with HAIP insertion and the median age of 54 (48-61) years. The burden of disease was >10 intra-hepatic metastatic foci in 59 (38.3%) patients. Patients received at least one cycle of systemic chemotherapy before HAIP insertion. Major complications occurred in 7 (4.6%) patients during their hospitalization and 13 (8.4%) patients developed biliary sclerosis during follow-up. A total of 148 patients (96.1%) received at least one-dose of HAIP chemotherapy with a median of 5 (4-7) cycles. 78 patients (56.5%) had a complete or partial response and 12 (7.8%) received a curative liver resection. CONCLUSION HAIP programs can be safely and effectively initiated in previously inexperienced centers with good response.

Abstract
697 Background: Pre-operative therapy for resectable pancreatic ductal adenocarcinoma (PDAC) may eliminate micro-metastatic disease early and help achieve negative surgical margins. The present study is based on the hypothesis that gemcitabine/nab-paclitaxel chemotherapy followed by chemo-radiation with fluoropyrimidine is a feasible and efficacious pre-operative treatment for borderline resectable or node-positive PDAC. Methods: This is a single-arm phase II trial to evaluate pre-operative treatment with 2 cycles of gemcitabine 1000 mg/m2 and nab-paclitaxel 125 mg/m2 on days 1, 8, 15 every 28 days followed by 50.4 Gy of intensity-modulated radiation therapy over 28 fractions with concurrent 5-fluorouracil or capecitabine prior to pancreatic resection. Patients were eligible if they met borderline resectable criteria or had abnormal regional nodes visible on contrast CT. After surgery, they were eligible to receive up to 4 additional cycles of gemcitabine/nab-paclitaxel. The primary endpoint was the R0 resection rate. Secondary endpoints included response to pre-operative therapy, overall toxicities, relapse-free survival, and overall survival. Results: Nineteen of 24 screened patients have been enrolled. Median age was 68, 10 (53%) were female, and 4 (21%) were non-Caucasian. Eleven (78%) had head of pancreas cancers, 13 (68%) exhibited both arterial and venous involvement, and 12 (63%) had positive clinical nodes. All 19 patients received 2 months of gemcitabine/nab-paclitaxel, of which 17 patients continued to chemo-radiation (1 developed metastatic disease and 1 moved out of state). In the interval between chemo-radiation and surgery, 3 developed metastatic disease, 1 became unresectable, 1 withdrew from study, and 1 was deemed too frail for surgery. Nine have undergone successful pancreatic resection, and 2 are pending resection. Conclusions: Pre-operative gemcitabine/nab-paclitaxel followed by chemo-radiation with fluoropyrimidine is feasible in patients with borderline resectable PDAC and represents another strategy to FOLFIRINOX-based therapy. A planned interim analysis is ongoing. Clinical trial information: NCT02427841.

Abstract
PURPOSE Propagation-based phase-contrast computed tomography (PB-CT) is a method for three-dimensional x-ray imaging that utilizes refraction, as well as absorption, of x rays in the tissues to increase the signal-to-noise ratio (SNR) in the resultant images, in comparison with equivalent conventional absorption-only x-ray tomography (CT). Importantly, the higher SNR is achieved without sacrificing spatial resolution or increasing the radiation dose delivered to the imaged tissues. The present work has been carried out in the context of the current development of a breast CT imaging facility at the Australian Synchrotron. METHODS Seven unfixed complete mastectomy samples with and without breast cancer lesions have been imaged using absorption-only CT and PB-CT techniques under controlled experimental conditions. The radiation doses delivered to the mastectomy samples during the scans were comparable to those approved for mammographic screening. Physical characteristics of the reconstructed images, such as spatial resolution and SNR, have been measured and compared with the results of the radiological quality assessment of the complete absorption CT and PB-CT image stacks. RESULTS Despite the presence of some image artefacts, the PB-CT images have outperformed comparable absorption CT images collected at the same radiation dose, in terms of both the measured objective image characteristics and the radiological image scores. The outcomes of these experiments are shown to be consistent with predictions of the theory of PB-CT imaging and previous reported experimental studies of this imaging modality. CONCLUSIONS The results presented in this paper demonstrate that PB-CT holds a high potential for improving on the quality and diagnostic value of images obtained using existing medical x-ray technologies, such as mammography and digital breast tomosynthesis (DBT). If implemented at suitable synchrotron imaging facilities, PB-CT can be used to complement existing imaging modalities, leading to more accurate breast cancer diagnosis.

Abstract
In this study we demonstrate the first direct comparison between synchrotron x-ray propagation-based CT (PB-CT) and cone-beam breast-CT (CB-CT) on human mastectomy specimens (N = 12) including different benign and malignant lesions. The image quality and diagnostic power of the obtained data sets were compared and judged by two independent expert radiologists. Two cases are presented in detail in this paper including a comparison with the corresponding histological evaluation. Results indicate that with PB-CT it is possible to increase the level of contrast-to-noise ratio (CNR) keeping the same level of dose used for the CB-CT or achieve the same level of CNR reached by CB-CT at a lower level of dose. In other words, PB-CT can achieve a higher diagnostic potential compared to the commercial breast-CT system while also delivering a considerably lower mean glandular dose. Therefore, we believe that PB-CT technique, if translated to a clinical setting, could have a significant impact in improving breast cancer diagnosis.

Abstract
BACKGROUND Management of elderly patients with solitary hepatocellular carcinoma (sHCC) is challenging with perceived clinicopathologic differences driving treatment options. We sought to determine factors predictive of disease control and survival after hepatic resection of sHCC in elderly patients. METHODS We identified n = 45 elderly patients (³≥65 yo) with sHCC treated with hepatic resection alone from our prospective database from 2003-16. Clinicopathologic data were analyzed and survival was assessed from the time of hepatic resection. RESULTS The median age was 75-years-old. Less than half of patients (47%) had viral hepatitis. At resection, the median Child-Pugh score was A6, median tumor size 5 cm, and mean AFP of 1050 (ng/mL). Major hepatectomy was performed in 23 patients (51%) with R0 resection achieved in 96%. Two patients (4%) had Grade III complications with no mortalities at 30 days and one death (2%) at 90-days. After R0 resection 44% (n = 20) had intrahepatic recurrence at a median of 32 months (95% CI: 15-46) with 20% (n = 9) developing extrahepatic recurrence at a median of 78 months (95% CI: 78-.). The median survival was 72 months (95% CI: 30-108 months). For patients with at least 3 years of follow-up, the 1-, 3-, and 5-year overall survival was 74%, 59%, and 50%, respectively. Mortality was associated with higher AFP and lower Prognostic Nutritional Index (PNI). CONCLUSION Carefully selected elderly patients with sHCC appear to have unique disease that is amenable to hepatic resection with low morbidity and mortality with excellent overall and recurrence-free survival.

Abstract
Background Hepatocellular carcinoma (HCC) with portal vein invasion (PVI) has a poor prognosis with limited treatment options. Intra-arterial brachytherapy (IAB) and transarterial chemoembolization (TACE) yield local control but risk accelerating liver dysfunction. The outcomes, survival, and safety of selective liver-directed treatment are reported. Methods Thirty-seven consecutive patients with HCC and PVI treated between 2009 and 2015 were reviewed from a prospectively collected database. Univariate analysis, Kaplan-Meier plots using the log-rank method, and multivariate analyses were performed. Statistical significance was defined as P<0.05. Overall survival was reported in months (median; 95% CI). Results Most patients (59%) had PVI identified at initial HCC diagnosis. The liver-directed therapy group (n=22) demonstrated a survival advantage versus the systemic/supportive care group (n=14) [23.6 (5.8, 30.9) vs. 6.0 (3.5, 8.8) months]. Patients indicated for liver directed therapy had unilateral liver involvement (100% vs. 43%, P<0.0001), lower median alkaline phosphatase (105.5 vs. 208.0, P=0.002), and lower mean Child-Turcotte-Pugh (CTP) score (5.9 vs. 7.2, P=0.04) and tolerated treatment without serious complications. Conclusions In HCC patients presenting with PVI, liver-directed therapy was safely performed in patients with limited venous involvement and preserved liver function. Liver-directed therapy extended survival for these patients indicated for palliative chemotherapy by traditional guidelines.

Abstract
In patients with colorectal cancer (CRC) that metastasizes to the liver, there are several key goals for improving outcomes including early detection, effective prognostic indicators of treatment response, and accurate identification of patients at high risk for recurrence. Although new therapeutic regimens developed over the past decade have increased survival, there is substantial room for improvement in selecting targeted treatment regimens for the patients who will derive the most benefit. Recently, there have been exciting developments in identifying high-risk patient cohorts, refinements in the understanding of systemic vs localized drug delivery to metastatic niches, liquid biomarker development, and dramatic advances in tumor immune therapy, all of which promise new and innovative approaches to tackling the problem of detecting and treating the metastatic spread of CRC to the liver. Our multidisciplinary group held a state-of-the-science symposium this past year to review advances in this rapidly evolving field. Herein, we present a discussion around the issues facing treatment of patients with CRC liver metastases, including the relationship of discrete gene signatures with prognosis. We also discuss the latest advances to maximize regional and systemic therapies aimed at decreasing intrahepatic recurrence, review recent insights into the tumor microenvironment, and summarize advances in noninvasive multimodal biomarkers for early detection of primary and recurrent disease. As we continue to advance clinically and technologically in the field of colorectal tumor biology, our goal should be continued refinement of predictive and prognostic studies to decrease recurrence after curative resection and minimize treatment toxicity to patients through a tailored multidisciplinary approach to cancer care.

Abstract
In patients with colorectal cancer (CRC) that metastasizes to the liver, there are several key goals for improving outcomes including early detection, effective prognostic indicators of treatment response, and accurate identification of patients at high risk for recurrence. Although new therapeutic regimens developed over the past decade have increased survival, there is substantial room for improvement in selecting targeted treatment regimens for the patients who will derive the most benefit. Recently, there have been exciting developments in identifying high-risk patient cohorts, refinements in the understanding of systemic vs localized drug delivery to metastatic niches, liquid biomarker development, and dramatic advances in tumor immune therapy, all of which promise new and innovative approaches to tackling the problem of detecting and treating the metastatic spread of CRC to the liver. Our multidisciplinary group held a state-of-the-science symposium this past year to review advances in this rapidly evolving field. Herein, we present a discussion around the issues facing treatment of patients with CRC liver metastases, including the relationship of discrete gene signatures with prognosis. We also discuss the latest advances to maximize regional and systemic therapies aimed at decreasing intrahepatic recurrence, review recent insights into the tumor microenvironment, and summarize advances in noninvasive multimodal biomarkers for early detection of primary and recurrent disease. As we continue to advance clinically and technologically in the field of colorectal tumor biology, our goal should be continued refinement of predictive and prognostic studies to decrease recurrence after curative resection and minimize treatment toxicity to patients through a tailored multidisciplinary approach to cancer care.

Abstract
Numerous murine models have been developed to study human cancers and advance the understanding of cancer treatment and development. Here, a preclinical, murine pancreatic tumor model of hepatic metastases via a hemispleen injection of syngeneic murine pancreatic tumor cells is described. This model mimics many of the clinical conditions in patients with metastatic disease to the liver. Mice consistently develop metastases in the liver allowing for investigation of the metastatic process, experimental therapy testing, and tumor immunology research.

Abstract
This review provides a brief overview, albeit from a somewhat personal perspective, of the evolution and key features of various hard X-ray phase-contrast imaging (PCI) methods of current interest in connection with translation to a wide range of imaging applications. Although such methods have already found wide-ranging applications using synchrotron sources, application to dynamic studies in a laboratory/clinical context, for example for in vivo imaging, has been slow due to the current limitations in the brilliance of compact laboratory sources and the availability of suitable high-performance X-ray detectors. On the theoretical side, promising new PCI methods are evolving which can record both components of the phase gradient in a single exposure and which can accept a relatively large spectral bandpass. In order to help to identify the most promising paths forward, we make some suggestions as to how the various PCI methods might be compared for performance with a particular view to identifying those which are the most efficient, given the fact that source performance is currently a key limiting factor on the improved performance and applicability of PCI systems, especially in the context of dynamic sample studies. The rapid ongoing development of both suitable improved sources and detectors gives strong encouragement to the view that hard X-ray PCI methods are poised for improved performance and an even wider range of applications in the near future.

Abstract
BACKGROUND Surgery remains the only potentially curative option for patients with hepatocellular carcinoma (HCC) and fibrolamellar carcinoma (FLC). We sought to investigate the differences over time in surgically managed FLC compared with conventional HCC using population-based data. STUDY DESIGN Using SEER data, we identified 7,225 patients with surgically managed FLC or HCC from 1986 to 2008. We examined differences in clinicopathologic and surgical factors associated with long-term survival. RESULTS Of the 7,225 patients, the majority had HCC (n = 7,135; 99%) vs FLC (n = 90; 1%). Patients with FLC were younger (25 years vs 59 years) and more often were women (44% vs 27%) than patients with HCC (both p < 0.001). Regional disease was more common among patients with FLC (42.2%) vs patients with HCC (22.1%) (p < 0.001). More than one-third of patients with FLC (36.9%) were operatively managed with a hemihepatectomy compared with patients with HCC, who were more often managed with a liver transplant (p < 0.001). On univariable analysis, there was a marked difference in overall survival, with patients with FLC surviving a median of 75 months vs 43 months for HCC (hazard ratio [HR]: 0.59; p = 0.001). There was a marked difference in survival when patients were stratified by localized (FLC, 78 months vs HCC, 49 months; p = 0.012) vs regional disease (FLC, 46 months vs HCC, 23 months; p = 0.002. CONCLUSIONS Patients with FLC have many clinicopathologic features that are different from those of patients with HCC, including younger age and female sex. Despite a higher likelihood of advanced disease at the time of diagnosis, surgically treated FLC patients had better long-term outcomes than patients with conventional HCC.

Impact of adjuvant external beam radiotherapy on survival in surgically resected gallbladder adenocarcinoma: a propensity score-matched Surveillance, Epidemiology, and End Results analysis.

Abstract
BACKGROUND We sought to define the utilization and effect of adjuvant external-beam radiotherapy (XRT) on patients having undergone curative-intent resection for gallbladder cancer (GBC). METHODS Using the Surveillance, Epidemiology, and End Results (SEER) database, we identified 5,011 patients with GBC who underwent resection between 1988 and 2009. The impact of XRT on survival was analyzed by the use of propensity-score matching by comparing clinicopathologic factors between patients who received resection only versus resection plus XRT. RESULTS Median age was 72 years, and most patients were female (73.4%); 66.2% patients had intermediate to poorly differentiated tumors, and 19.1% had lymph node metastasis. The majority (75.0%) had "localized" disease by Surveillance, Epidemiology, and End Results classification. A total of 899 patients (17.9%) received XRT whereas 4,112 patients did not. Factors associated with receipt of XRT were younger age (odds ratio [OR] 5.33), tumor extension beyond the serosa (OR 1.55), intermediate- to poorly differentiated tumors (OR 1.56), and lymph node metastasis (OR 2.59) (all P < .05). Median and 1-year survival were 15 months and 59.0%, respectively. On propensity-matched multivariate model, despite having more advanced tumors, XRT was independently associated with better long-term survival at 1 year (hazard ratio 0.45; P < .001), but not 5 years (hazard ratio 1.06; P = .50). CONCLUSION A total of 18% of patients with GBC received XRT after curative intent surgery. The use of adjuvant XRT was associated with a short-term survival benefit, but the benefit dissipated over time.

Abstract
BACKGROUND The goal of this study was to investigate the surgical management and outcomes of patients with primary colorectal cancer (CRC) and synchronous liver metastasis (sCRLM). STUDY DESIGN Using a multi-institutional database, we identified 1,004 patients treated for sCRLM between 1982 and 2011. Clinicopathologic and outcomes data were evaluated with uni- and multivariable analyses. RESULTS A simultaneous CRC and liver operation was performed in 329 (33%) patients; 675 (67%) underwent a staged approach ("classic" staged approach, n = 647; liver-first strategy, n = 28). Patients managed with the liver-first approach had more hepatic lesions and were more likely to have bilateral disease than those in the other 2 groups (p < 0.05). The use of staged operative strategies increased over the time of the study from 58% to 75% (p < 0.001). Liver-directed therapy included hepatectomy (90%) or combined resection + ablation (10%). A major resection (>3 segments) was more common with a staged approach (39% vs 24%; p < 0.001). Overall, 509 patients (50%) received chemotherapy in either the preoperative (22%) or adjuvant (28%) settings, with 11% of patients having both. There were 197 patients (20%) who had a complication in the postoperative period, with no difference in morbidity between staged and simultaneous groups or major vs minor hepatectomies (p > 0.05). Ninety-day postoperative mortality was 3.0%, with no difference between simultaneous and staged approaches (p = 0.94). The overall median and 5-year survivals were 50.9 months and 44%, respectively; long-term survival was the same regardless of the operative approach (p > 0.05). CONCLUSIONS Simultaneous and staged resections for sCRLM can be performed with comparable morbidity, mortality, and long-term oncologic outcomes.
