Abstract
Purpose: This study evaluated the effect of an increase in the time interval between hepatic intra-arterial injection of 99mTc-macroaggregated albumin (MAA) and hepatic artery perfusion scintigraphy (HAPS) on the lung shunt fraction (LSF) and perfused volume (PV) calculations in the treatment planning of selective internal radiation therapy (SIRT). Methods: The authors enrolled 51 HAPS sessions from 40 patients diagnosed with primary or metastatic liver malignancy. All patients underwent scan at the first and fourth hour after hepatic arterial injection of 99mTc-MAA. Based on single-photon emission computed tomography images, LSF values were measured from each patient's first and fourth hour images. PV1 and PV4 were also calculated based on three-dimensional images using 5% and 10% cutoff threshold values and compared with each other. Results: The authors found that the median of LSF4 was statistically significantly higher than LSF1 (3.05 vs. 4.14, p ≤ 0.01). There was no statistically significant difference between PV1 and PV4 on the 10% (p = 0.72) thresholds. Conclusions: LSF values can be overestimated in case of delayed HAPS, potentially leading to treatment cancellation due to incorrectly high results in patients who could benefit from SIRT. Threshold-based PV values do not significantly change over time; nevertheless, keeping the short interval time would be safer.

Abstract
BACKGROUND Peptide receptor radionuclide therapy and selective internal radiation therapy are effective radionuclide therapy modalities for unresectable metastatic neuroendocrine tumor patients that cannot be controlled with somatostatin analogs. The present study is intended to evaluate the therapeutic efficacy and toxicity of the combined therapy of selective internal radiation therapy and peptide receptor radionuclide therapy and stand-alone selective internal radiation therapy in patients with neuroendocrine tumor, a liver-dominant disease. METHODS This cohort consists of 27 patients with metastatic neuroendocrine tumor and liver-dominant disease. They were grouped as the patients who were treated with selective internal radiation therapy for unresectable liver metastasis (n = 15) and the patients who received a combination of selective internal radiation therapy and peptide receptor radionuclide therapy (n = 12) for hepatic and extrahepatic metastasis. Treatment efficacy and treatment-associated toxicity were retrospectively assessed in both groups. RESULTS The objective treatment response and stable disease were found in 13 patients (86.6%) in the selective internal radiation therapy group and eight patients (66.6%) in the selective internal radiation therapy + peptide receptor radionuclide therapy group. The median overall survival rate was found to be 34.9 months, in the selective internal radiation therapy group and 67.5 months in the selective internal radiation therapy + peptide receptor radionuclide therapy group (P = 0.217). The median progression-free survival data was not reached, and the mean values of progression-free survival were 53.1 ± 9.9 months in the selective internal radiation therapy group, and 27.2 ± 5.9 months in the selective internal radiation therapy + peptide receptor radionuclide therapy group (P = 0.561). Temporary lymphopenia was the most common side effect. Grade 1-2 hepatotoxicity was observed to be 6.6% in the selective internal radiation therapy group, while it was not observed in selective internal radiation therapy + peptide receptor radionuclide therapy group. CONCLUSIONS In the neuroendocrine tumors with liver-dominant metastatic disease, personalized selective internal radiation therapy and peptide receptor radionuclide therapy and their combinations result in increased survival rates. Selective internal radiation therapy alone could be an effective treatment in patients with liver-limited and -dominant disease.

Abstract
BACKGROUND Though nowadays a palliative pancreaticoduodenectomy (PD) can be performed safely with relatively low mortality and acceptable morbidity rates in experienced centers, there have been no studies on the routine use of a palliative PD or on the advantages of performing surgical resection as a debulking procedure. Furthermore, the impact of resection margins on survival outcomes has been a matter of controversy. Therefore, this study aimed to clarify the role of robotic PD (RPD) in pancreatic and periampullary adenocarcinomas with positive resection margins. METHODS Patients undergoing RPDs and open PDs (OPDs) were included in this study. Based on the resection margins, the patients were divided into the R0, R1, and R2 PD groups. Surgical risks and survival outcomes were analyzed. RESULTS There were 348 PDs, including 29 (8.3%) palliative and 319 (91.7%) curative. Primary tumor origin, tumor sizes, perineural invasions, and abnormal serum carcinoembryonic antigen (CEA) levels were factors leading to palliative resection. The multivariate analysis showed that only pancreatic head adenocarcinomas and abnormal serum CEA levels (>5 ng/mL) were independent predictors. The surgical risks between curative and palliative PD were similar. There were no significant differences in the surgical risks and other surgical parameters between palliative RPDs and OPDs. For curative resection, RPDs resulted in less blood loss, greater harvested lymph nodes yield, less postoperative complications, less delayed gastric emptying, and shorter hospital stays than OPDs. The survival outcome was significantly better following R0 resection in overall periampullary adenocarcinomas, whereas a significant survival difference was shown only between the R0 and R2 resections for pancreatic head adenocarcinomas. CONCLUSION Compared with R0 PDs, palliative R1 PDs could benefit patients with pancreatic head adenocarcinomas when considering survival outcomes without increasing surgical risks. RPD can be considered for curative purposes and as an alternative for palliative management.

Abstract
BACKGROUND Pancreatic neuroendocrine tumors (PNETs) are rare pancreatic neoplasms. About 40-80% of patients with PNET are metastatic at presentation, usually involving the liver (40-93%). Liver metastasis represents the most significant prognostic factor. The aim of this study is to present an up-to-date review of treatment options for patients with liver metastases from PNETs. METHODS A systematic literature search was performed using the PubMed database to identify all pertinent studies published up to May 2018. RESULTS The literature search evaluated all the therapeutic options for patients with liver metastases of PNETs, including surgical treatment, loco-regional therapies, and pharmacological treatment. All the different treatment options showed particular indications in different presentations of liver metastases of PNET. Surgery remains the only potentially curative therapeutic option in patients with PNETs and resectable liver metastases, even if relapse rates are high. Efficacy of medical treatment has increased with advances in targeted therapies, such as everolimus and sunitinib, and the introduction of radiolabeled somatostatin analogs. Several techniques for loco-regional control of metastases are available, including chemo- or radioembolization. CONCLUSIONS Treatment of patients with PNET metastases should be multidisciplinary and must be personalized according to the features of individual patients and tumors.

Abstract
Liver metastasis is the most common site of colorectal cancer (CRC) metastasis. Approximately half of all colorectal cancer patients will develop liver metastases. Although radical surgery is the standard treatment modality, only 10-20% of patients are deemed eligible for resection. Despite advances in survival with chemotherapy, surgical resection is still considered the only curative option for patients with liver metastases. Much effort has been expended to address patients with metastatic liver disease. The majority of evidence stated a significant survival benefit with surgical resection to reach an overall 5-year survival rate of 35-55% after hepatic resection. However, still majority of patients will experience disease recurrence even after a successful resection. In this review, we describe current status and controversies related to treatment options for CRC liver metastases and its potential for enhancing oncologic outcomes and improving quality of life.

Abstract
OBJECTIVE The purpose of the present study is to evaluate Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, tumor attenuation criteria, Choi criteria, and European Organization for Research and Treatment of Cancer (EORTC) PET criteria as measures of response and subsequent predictors of liver progression-free survival (PFS) after radioembolization (RE) of colorectal liver metastases (CLM). The study also assesses interobserver variability for measuring tumor attenuation using a single 2D ROI on a simple PACS workstation. MATERIALS AND METHODS We performed a retrospective review of the clinical RE database at our institution, to identify patients treated in the salvage setting for CLM between December 2009 and March 2013. Response was evaluated on FDG PET scans, with the use of EORTC PET criteria, and on portal venous phase CT scans, with the use of RECIST 1.1, tumor attenuation criteria, and Choi criteria. Two independent blinded observers measured tumor attenuation using a single 2D ROI. The intraclass correlation coefficient (ICC) for interobserver variability was assessed. Kaplan-Meier methodology was used to calculate liver PFS, and the log-rank test was used to assess the response criteria as predictors of liver PFS. RESULTS A total of 25 patients with 46 target tumors were enrolled in the study. The ICC was 0.95 at baseline and 0.98 at response evaluation. Among the 25 patients, more responders (i.e., partial response) were identified on the basis of EORTC PET criteria (n = 14), Choi criteria (n = 15), and tumor attenuation criteria (n = 13) than on the basis of RECIST 1.1 (n = 2). The median liver PFS was 3.0 months (95% CI, 2.1-4.0 months). Response identified on the basis of EORTC PET criteria (p < 0.001), Choi criteria (p < 0.001), or tumor attenuation criteria (p = 0.01) predicted liver PFS; however, response identified by RECIST 1.1 did not (p = 0.1). CONCLUSION RECIST 1.1 has poor sensitivity for detecting metabolic responses classified by EORTC PET criteria. EORTC PET criteria, Choi criteria, and tumor attenuation criteria appear to be equally reliable surrogate imaging biomarkers of liver PFS after RE in patients with CLM.

Abstract
PURPOSE Although some algorithms are defined for the treatment of advanced hepatocellular carcinoma (HCC), the expected survival cannot be prolonged as it is intended. Treatment options for this group of patients are limited. Radioembolization with yttrium-90 (Y-90) microspheres is a new treatment modality, which has also been used in advanced HCC patients. In this study, the authors aimed to assess the efficiency of radioembolization with Y-90 microspheres and evaluate prognostic factors that influence the survival in HCC patients. PATIENTS AND METHODS The authors retrospectively evaluated data of 29 HCC patients who had radioembolization with Y-90 resin or glass microspheres between May 2009 and January 2014. Patient survival was evaluated by using the Kaplan-Meier method. Subgroup comparisons in terms of age, sex, prior treatment status before radioembolization, tumor burden, time between HCC diagnosis and radioembolization, alpha fetoprotein (AFP) level before radioembolization, presence of portal vein thrombosis (PVT), hepatopulmonary shunt ratio, extrahepatic disease burden, multifocality, bilaterality, Eastern Cooperative Oncology Group (ECOG), Child-Pugh, and Barcelona Clinic Liver Cancer (BCLC) status were performed to evaluate prognostic factors that affected survival. RESULTS There were 29 HCC patients (mean age: 59.9±12 years) in the patient group. Grade ≤1 and 2 ECOG performance status was present in 19 and 10 patients, respectively. Twenty-six patients were classified as Child A and 3 patients as Child B. According to the BCLC staging system, 18 patients were in stage B and 11 patients were in stage C. PVT was diagnosed in 12 patients. The median follow-up was 15 months. The median overall survival was 17±2.5 months. BCLC disease stage was a significant prognostic variable associated with survival, but other parameters, even the presence of PVT, were found to be not significantly affecting survival. CONCLUSION Radioembolization provides favorable survival time in advanced HCC patients. Even patients who are not eligible for transarterial chemoembolization due to PVT can have radioembolization without a decrease in the median survival time.

Abstract
BACKGROUND Many patients with liver malignancies are not candidates for resection, and systemic therapies are often not effective. Radioembolization (RE) is an alternative treatment for this group of patients. The safety and efficacy of RE with yttrium 90 (Y90) in patients with hepatocellular carcinoma (HCC) or metastatic colon cancer to the liver have been proven in several studies. However, fewer studies have focussed on the safety and efficacy of RE with Y90 in other extrahepatic primary and secondary liver cancers. The effect on outcomes of concomitant use of Y90 with a systemic therapy is still currently under investigation. SUMMARY A review of the published data on the use of RE as stand-alone, concomitant or sequential with other treatment modalities in HCC and other primary and secondary liver cancer is reported here. KEY MESSAGE RE for the treatment of HCC and other extrahepatic, primary and secondary liver cancer has reasonable efficacy and acceptable toxicities. Definitive studies to establish the role of RE in the treatment of such malignancies are warranted.

Abstract
Radioembolization with yttrium-90 microspheres offers an alternative treatment option for patients with unresectable intrahepatic cholangiocarcinoma (ICC). However, the rarity and heterogeneity of ICC makes it difficult to draw firm conclusions about treatment efficacy. Therefore, the goal of the current study is to systematically review the existing literature surrounding treatment of unresectable ICCs with yttrium-90 microspheres and provide a comprehensive review of the current experience and clinical outcome of this treatment modality. We performed a comprehensive search of electronic databases for ICC treatment and identified 12 studies with relevant data regarding radioembolization therapy with yttrium-90 microspheres. Based on pooled analysis, the overall weighted median survival was 15.5 months. Tumour response based on radiological studies demonstrated a partial response in 28% and stable disease in 54% of patients at three months. Seven patients were able to be downstaged to surgical resection. The complication profile of radioembolization is similar to that of other intra-arterial treatment modalities. Overall survival of patients with ICC after treatment with yttrium-90 microspheres is higher than historical survival rates and shows similar survival to those patients treated with systemic chemotherapy and/or trans-arterial chemoembolization therapy. Therefore, the use of yttrium-90 microspheres should be considered in the list of available treatment options for ICC. However, future randomized trials comparing systemic chemotherapy, TACE and local radiation will be required to identify the optimal treatment modality for unresectable ICC.

Abstract
PURPOSE To provide a first evidence-based review of the literature on the role of fluorine-18-fluorodeoxyglucose positron emission tomography and positron emission tomography/computed tomography (FDG-PET and PET/CT) in patients with colorectal liver metastases (CRLM) undergoing selective internal radiation therapy (SIRT) with yttrium-90 ((90)Y) microspheres. METHODS A comprehensive computer literature search was conducted to find relevant published articles on whole-body FDG-PET or PET/CT in patients with CRLM undergoing SIRT. RESULTS We identified 19 studies including 833 patients with CRLM undergoing SIRT. The role of FDG-PET or PET/CT was analysed in treatment planning, treatment response evaluation, and as prognostic tool. CONCLUSION FDG-PET and PET/CT provide additional information in treatment evaluation of CRLM patients treated with SIRT and may have a role in treatment planning and patient selection. FDG-PET/CT is emerging as good prognostic tool in these patients.
