The aim of this single-center, open-label phase II study was to assess the efficacy of image-guided high-dose-rate (HDR) brachytherapy (iBT) compared with conventional transarterial embolization (cTACE) in unresectable hepatocellular carcinoma. Seventy-seven patients were treated after randomization to iBT or cTACE, as single or repeated interventions. Crossover was allowed if clinically indicated. The primary endpoint was time to untreatable progression (TTUP). Eligibility criteria included a Child–Pugh score of ≤ 8 points, absence of portal vein thrombosis (PVT) at the affected liver lobe, and ≤ 4 lesions. Survival was analyzed by using the Cox proportional hazard model with stratification for Barcelona Clinic Liver Cancer (BCLC) stages. Twenty patients were classified as BCLC-A (iBT/cTACE 8/12), 35 as BCLC-B (16/19), and 22 as BCLC-C (13/9). The 1-, 2-, and 3-year TTUP probabilities for iBT compared with cTACE were 67.5% versus 55.2%, 56.0% versus 27.4%, and 29.5% versus 11.0%, respectively, with an adjusted hazard ratio (HR) of 0.49 (95% confidence interval 0.27–0.89; p = 0.019). The 1-, 2-, and 3-year TTPs for iBT versus cTACE were 56.0% versus 28.2%, 23.9% versus 6.3%, and 15.9% versus 6.3%, respectively, with an adjusted HR of 0.49 (0.29–0.85; p = 0.011). The 1-, 2-, and 3-year OS rates were 78.4% versus 67.7%, 62.0% versus 47.3%, and 36.7% versus 27.0%, respectively, with an adjusted HR of 0.62 (0.33–1.16; p = 0.136). This explorative phase II trial showed a superior outcome of iBT compared with cTACE in hepatocellular carcinoma and supports proceeding to a phase III trial.

This prospective study compared a 1-d SPECT/CT protocol with the commonly used 3-d protocol for somatostatin receptor scintigraphy in patients with gastroenteropancreatic neuroendocrine neoplasms. Additionally, the influence of SPECT/CT on patient management was evaluated. Methods: From October 2011 to October 2012, all gastroenteropancreatic neuroendocrine neoplasm patients undergoing restaging with somatostatin receptor scintigraphy on a modern SPECT/CT device were enrolled in this study. The protocol consisted of planar imaging at 4, 24, and 48 h; low-dose SPECT/CT at 24 and 48 h; diagnostic CT at 24 h using a triple-phase delay after administration of contrast; and diagnostic SPECT/CT at 24 h. All components of the imaging data were reassessed by 3 masked interpreters. The results were compared with a reference standard based on all clinical, imaging, and histopathology follow-up data available (follow-up range, 24–36 mo; mean, 29.9 mo). The reference standard was defined by a study-specific interdisciplinary tumor board that also reassessed treatment decisions. Results: Thirty-one patients were eligible for analysis (18 men and 13 women; mean age, 60.4 y). Ten had no imaging signs of disease and remained disease-free during follow-up. Twenty-one had persistent or recurrent disease (82 lesions: 24 in the liver, 21 in the lymph nodes, 16 in bone, 12 in the pancreas, and 9 in other locations). The respective lesion detection rates for interpreters 1, 2, and 3 were 51.9%, 49.4%, and 71.6% for low-dose SPECT/CT at 24 h; 51.9%, 55.6%, and 67.9% for low-dose SPECT/CT at 48 h; 63.0%, 70.4%, and 85.2% for diagnostic CT; and 77.8%, 84.0%, and 88.9% for diagnostic SPECT/CT. Interobserver agreement was moderate for diagnostic SPECT/CT (κ = 0.44), diagnostic CT (κ = 0.43), low-dose SPECT/CT at 48 h (κ = 0.61), and low-dose SPECT/CT at 24 h (κ = 0.55). For planar imaging, interobserver agreement was fair after 48 h (κ = 0.36) and 24 h (κ = 0.38) and moderate after 4 h (κ = 0.42). Every lesion detectable on planar imaging or low-dose SPECT/CT was also detectable on diagnostic SPECT/CT. The CT and SPECT components of diagnostic SPECT/CT strongly complemented each other, as 34 of 82 lesions (41.4%) were detected on only the CT component or only the SPECT component. Therapeutic management was influenced by the diagnostic SPECT/CT interpretation in 8 of 31 patients (25.8%). Conclusion: The highest detection rates were achieved by diagnostic SPECT/CT. Thus, a more patient-friendly 1-d protocol is feasible. Furthermore, multiphase SPECT/CT affected management in about a quarter of patients.

Staple line leak after laparoscopic sleeve gastrectomy (LSG) still represents the most feared complication. The purpose of this study was to investigate whether there are factors that increase the risk for a leakage. Furthermore, we aimed to analyze the impact of a leak on weight change and resolution of comorbidities. Since 2005, data from obese patients that undergo bariatric procedures in Germany are prospectively registered. For the current analysis, all adult subjects that had undergone primary LSG from 2005 to 2014 were considered. Overall, 241/15,756 (1.53%) patients experienced a leak. The occurrence of a leakage resulted in a significant increase of the mortality rate (3.7 vs. 0.2%; p

Vor allem bei eingeschrankter periphervenoser Gefassituation werden leistungsfahige und vertragliche Systeme benotigt, die neben der Moglichkeit der Blutabnahme eine einfache und suffiziente zentralvenose Medikamentengabe bei hoher Lebensqualitat des Patienten im Langzeitverlauf garantieren konnen. Heutzutage spielt der Einsatz zentralvenoser Katheter eine grose Rolle sowohl in der Behandlung kritisch kranker Patienten als auch bei Patienten, die eine parenterale Ernahrung, eine Antibiotika- oder eine Chemotherapie erhalten bzw. bei Dialysepatienten und bei Patienten mit schwierigen venosen Verhaltnissen. Die zentralvenosen Katheter konnen generell in 4 Gruppen unterteilt werden: Als Zugange werden in der Regel die V. subclavia, die V. jugularis interna, bei Portsystemen auch die V. jugularis externa und in selteneren Fallen die V. femoralis verwendet. Bei ausgeschopften Venenverhaltnissen konnen unkonventionelle Zugangswege wie die obere und untere Hohlvene und die V. azygos angegangen werden.

Summary Background & aims Malnutrition is a common, hence frequently underdiagnosed condition in patients with liver cirrhosis as well as in patients with cancer and has been shown to have a negative impact on survival in these patients. Frequently applied screening tools including anthropometric measurements or laboratory parameters to screen for malnutrition are not suitable for patients with liver cirrhosis with additional pathophysiological mechanisms leading to hypoalbuminemia and edema. Prospective data on the prevalence and prognostic impact of malnutrition in patients with HCC are scarce. Methods Fifty-one consecutive patients with hepatocellular carcinoma were prospectively enrolled into this study and screened for malnutrition by anthropometric measurements, the MNA score, the NRS score, laboratory work-up, and BIA measurement. The results of the different screening tools were compared to each other and with the BIA assessment and correlated with the outcome of patients. Results The calculation of a body mass index (BMI) was not suitable to identify malnourished patients with HCC. The MNA identified 19, the NRS score 17 patients at a risk for malnutrition. BIA revealed a reduction in relative body cell mass in 12 patients. Univariate Cox regression analyses identified tumor stage, MNA score, and phase angle obtained by BIA as significant factors with influence on survival. Multivariate analyses confirmed the phase angle at a cut-off of 4.8 to be an independent factor. Conclusions A significant proportion of patients with HCC is malnourished or at risk for malnutrition. Screening questionnaires and BIA measurement are superior to pure anthropometric measurements to identify the condition that negatively influences survival. The phase angle derived from body impedance analysis is an independent prognostic factor in patients with HCC.

Background HCC predominantly develops in the condition of chronic inflammation that has led to liver cirrhosis. A small proportion of patients with HCC is diagnosed in the non-cirrhotic liver (NCL). Data on patients with HCC in NCL in advanced stages are scarce. Methods A retrospective analysis was performed comparing 93 patients with HCC in NCL to 571 patients with HCC in liver cirrhosis (LC) with respect to clinical and demographic characteristics. Also factors influencing survival in patients with HCC in NCL were analyzed. Results Patients with HCC in NCL were diagnosed at older age and in more advanced tumor stages than patients with LC. More than 25% of patients with HCC in NCL presented with extrahepatic metastases. Only a minority of patients with HCC in NCL lacked any sign of hepatic damage. Risk factors for LC and risk factors for NAFLD are present in the majority of patients with HCC in NCL. The BCLC classification corresponded with the survival of patients with HCC in NCL although the therapeutic options differ from those for patients with liver cirrhosis. Conclusions It will be one of the major challenges in the future to awake awareness of carrying a risk of hepatic malignancies in patients with chronic liver diseases apart from liver cirrhosis, especially in NAFLD. Surveillance programs need to be implemented if these are cost-effective.

Background: Adherence to surveillance recommendations for patients at risk of developing hepatocellular carcinoma (HCC) is influenced by several factors, including the etiology of chronic liver disease. Aim: The aim of this study was to analyze whether tumor stage at diagnosis and prognosis differ in patients with alcohol-related HCC compared to those with chronic viral hepatitis-related HCC. Patients and Methods: Medical records of 650 patients diagnosed with HCC between 1994 and 2011 were analyzed retrospectively. Groups were formed from patients having either alcohol abuse or viral hepatitis (chronic hepatitis B or C virus infection) as the only known HCC risk factors. Demographic data (age and gender), tumor stage at diagnosis, survival, liver function [Child–Pugh–Turcotte (CPT) score] in patients with liver cirrhosis, complications of liver cirrhosis, and serologic parameters were compared between the two groups. Results: A total of 393 HCC cases (male 84%, median age 65 years) were identified, with alcohol abuse as the causative factor in 76.8% and chronic viral hepatitis in 23.2%. In patients with alcohol abuse, 278 (92.1%) were diagnosed with liver cirrhosis (CPT A 49.3%, CPT B 31.1%, CPT C 9.6%), while in patients with viral hepatitis, 84 (92.3%) suffered from liver cirrhosis (CPT A 59.3%, CPT B 23.1%, CPT C 8.8%). Tumor stage in patients with alcohol abuse was Barcelona Clinic Liver Cancer (BCLC) C in 43.7%, BCLC B in 30.5%, and BCLC A in 14.6%. Patients with viral hepatitis showed a trend toward diagnosis at an earlier tumor stage (BCLC B 35.2%, BCLC C 34.1%, BCLC A 22.2%). Etiology of liver cirrhosis did not significantly influence survival in intermediate and advanced tumor stages, but BCLC-A patients with alcohol-related disease demonstrated prolonged survival compared to patients with viral hepatitis. Conclusion: Tumor stage at diagnosis of HCC is influenced by the etiology of underlying chronic liver disease and is more progressed in patients having a disease with alcoholic etiology. Majority of HCC patients are not diagnosed at a curable stage, which underlines the need for specialized care for all patients with chronic liver disease, independent of etiology and consequent adherence to current surveillance guidelines.

Introduction: The incidence of hepatocellular cancer (HCC) continues to rise in Europe with a shift of the primary cause towards alcoholic and non-alcoholic fatty liver disease. Metabolic factors like diabetes mellitus and overweight have been identified as significant risk factors for HCC development. Patients and Methods: A retrospective analysis in a large single-center cohort of 650 patients diagnosed with HCC was performed. Demographic characteristics, risk factors, tumor stage at diagnosis and survival were evaluated. Results: Among 650 patients (aged 17-87 years, with a male: female ratio of 4:1), 80.8% had underlying liver cirrhosis. Alcohol abuse was identified as the only risk factor for liver cirrhosis in 52.2% of patients. Viral infection with hepatitis C and hepatitis B was present in 13.7 and 3.6% of patients, respectively. 66.1% of patients with HCC were overweight with a body mass index exceeding 25, 25.5% even exceeding 30; 52% of patients had diabetes mellitus. Conclusion: Strategies aiming at prevention and surveillance of patients at risk to develop HCC in the future need to widen the focus from patients with chronic viral hepatitis and a history of alcohol abuse to patients with metabolic risk factors.
