Early onset of hypertension and serum electrolyte changes as potential predictive factors of activity in advanced hcc patients treated with sorafenib: Results from a retrospective analysis of the HCC-AVR group

Hypertension (HTN) is frequently associated with the use of angiogenesis inhibitors targeting the vascular endothelial growth factor pathway and appears to be a generalized effect of this class of agent. We investigated the phenomenon in 61 patients with advanced hepatocellular carcinoma (HCC) receiving sorafenib. Blood pressure and plasma electrolytes were measured on days 1 and 15 of the treatment. Patients with sorafenib-induced HTN had a better outcome than those without HTN (disease control rate: 63.4% vs. 17.2% (p=0.001); progression-free survival 6.0 months (95% CI 3.2-10.1) vs. 2.5 months (95% CI 1.9-2.6) (p<0.001) and overall survival 14.6 months (95% CI9.7-19.0) vs. 3.9 months (95% CI 3.1-8.7) (p=0.003). Sodium levels were generally higher on day 15 than at baseline (+2.38, p<0.0001) in the group of responders (+4.95, p <0.0001) compared to patients who progressed (PD) (+0.28, p=0.607). In contrast, potassium was lower on day 14 (-0.30, p=0.0008) in the responder group (-0.58, p=0.003) than in those with progressive disease (-0.06, p=0.500). The early onset of hypertension is associated with improved clinical outcome in HCC patients treated with sorafenib. Our data are suggestive of an activation of the renin-angiotensin system in patients with advanced disease who developed HTN during sorafenib treatment

Computed tomography based analyses of body mass composition in HER2 positive metastatic breast cancer patients undergoing first line treatment with pertuzumab and trastuzumab

Body composition parameters (BCp) have been associated with outcome in different tumor types. However, their prognostic value in patients with HER2-positive metastatic breast cancer (BC) receiving first line treatment with dual anti-HER2 antibody blockade is unknown. Preclinical evidences suggest that adipocytes adjacent to BC cells can influence response to anti-HER2 treatments. We retrospectively analyzed Computed Tomography (CT)-based BCp from 43 patients with HER2-positive metastatic BC who received first line pertuzumab/trastuzumab-based treatment between May 2009 and March 2020. The impact of baseline CT-based BCp on progression-free survival (PFS) was tested using Kaplan-Meier estimates and univariate and multivariate Cox regression models. We found a significantly worse PFS for patients with high baseline subcutaneous fat index (median 7.9 vs 16.1 months, p = 0.047, HR = 2.04, 95%CI 1-4.17) and for those with high total abdominal fat index (8.1 vs 18.8 months, p = 0.030, HR = 2.17, 95%CI 1.06-4.46). Patients with baseline sarcopenia did not show shorter PFS compared to those without sarcopenia (10.4 vs 9.2 months, p = 0.960, HR = 0.98, 95%CI 0.47-2.03). Total abdominal fat index remained a significant predictor of PFS at multivariate analysis. Our findings suggest that a high quantity of total abdominal fat tissue is a poor prognostic factor in patients receiving trastuzumab/pertuzumab-based first-line treatment for HER2-positive metastatic BC

Efficacy of radioembolization according to tumor morphology and portal vein thrombosis in intermediate–advanced hepatocellular carcinoma

Purpose: We analyzed overall survival (OS) following radioembolization according to macroscopic growth pattern (nodular vs infiltrative) and vascular invasion in intermediate-advanced hepatocellular carcinoma (HCC). Methods: Between September 2005 and November 2013, 104 patients (50.0% portal vein thrombosis [PVT], 29.8% infiltrative morphology) were treated. Results: Median OS differed significantly between patients with segmental and lobar or main PVT (p = 0.031), but was 17 months in both those with patent vessels and segmental PVT. Median OS did not differ for infiltrative and nodular HCC. Median OS was prolonged in patients with a treatment response at 3 months (p = 0.023). Prior TACE was also a significant predictor of improved OS. Conclusion: A further indication for radioembolization might be infiltrative HCC, since OS was similar to nodular types

Textbook Outcome After Trans-arterial Chemoembolization for Hepatocellular Carcinoma

PurposeTextbook Outcome (TO) is inclusive of quality indicators and it not been provided for trans-arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC).Materials and methodsData on treatment-naïve HCC patients receiving TACE from 10 centers were reviewed. TO was defined as "no post-TACE grade 3-4 complications, no prolonged hospital stay (defined as a post-procedure stay ≤ 75th percentile of the median values from the total cohort), no 30-day mortality/readmission and the achievement of an objective response (OR) at post-TACE imaging." Grade of adverse event was classified according to the Common Terminology Criteria for Adverse Events and short-term efficacy was assessed by response. Pooled estimates were calculated to account for hospital's effect and risk-adjustment was applied to allow for diversity of patients in each center.ResultsA total of 1124 patients (2014-2018) fulfilling specific inclusion criteria were included. Baseline clinical features showed considerable heterogeneity (I2 > 0.75) across centers. TACE-related mortality was absent in 97.6%, readmission was not required after 94.9% of procedures, 91.5% of patients had no complication graded 3-4, 71.8% of patients did not require prolonged hospitalization, OR of the target lesion was achieved in 68.5%. Risk-adjustment showed that all indicators were achieved in 43.1% of patients, and this figure was similar across centers. The median overall survival for patients who achieved all indicators was 33.1 months, 11.9 months longer than for patients who did not.ConclusionsA useful benchmark for TACE in HCC patients has been developed, which provides an indication of survival and allows for a comparison of treatment quality across different hospitals

Guidelines on the diagnosis, treatment and management of visceral and renal arteries aneurysms: a joint assessment by the Italian Societies of Vascular and Endovascular Surgery (SICVE) and Medical and Interventional Radiology (SIRM)

: The objective of these Guidelines is to provide recommendations for the classification, indication, treatment and management of patients suffering from aneurysmal pathology of the visceral and renal arteries. The methodology applied was the GRADE-SIGN version, and followed the instructions of the AGREE quality of reporting checklist. Clinical questions, structured according to the PICO (Population, Intervention, Comparator, Outcome) model, were formulated, and systematic literature reviews were carried out according to them. Selected articles were evaluated through specific methodological checklists. Considered Judgments were compiled for each clinical question in which the characteristics of the body of available evidence were evaluated in order to establish recommendations. Overall, 79 clinical practice recommendations were proposed. Indications for treatment and therapeutic options were discussed for each arterial district, as well as follow-up and medical management, in both candidate patients for conservative therapy and patients who underwent treatment. The recommendations provided by these guidelines simplify and improve decision-making processes and diagnostic-therapeutic pathways of patients with visceral and renal arteries aneurysms. Their widespread use is recommended

Biliary Variant in a Potential Liver Donor

A55 year-oldmanwith no known medical conditions or surgical history presented to our hospital to be evaluated as potential living liver donor. In our centre donor candidates are evaluated using a specific living donor protocol; this includes imaging studies for liver volumetrics (to quantify the amount of parenchyma that could be donated versus the remnant) and liver vascular anatomy, and magnetic resonance cholangiopancreatography (MRCP) to evaluate anatomy of the biliary tree. Computed tomography scanning was performed to estimate volume of the right and left lobes of the liver: the right lobe would be harvested for transplantation into the recipient, while the left would be the donor\u2019s remnant liver; the test confirmed adequate volume of both liver lobes. MRCP showed biliary variants characterized by a right posterior hepatic duct (RPHD), which in classic biliary anatomy fuses with the right anterior duct to constitute a short right hepatic duct, draining directly into the common hepatic duct (CHD) (Fig. 1A, arrow). MRCP also showed that the cystic duct, which usually drains into the lateral aspect of the CHD below its origin, drained directly into theRPHDabove its confluence with theCHD(Fig. 1B, arrow). Classic biliary anatomy appears in about 58% of the population, while the variant in which RPHD drains directly into the CHD has a prevalence of approximately 5% [1]. These anatomical biliary variants are relevant in potential donors evaluated for living donor liver transplantation

Calculation of conversion factors for effective dose for various interventional radiology procedures

Purpose: To provide dose-area-product (DAP) to effective dose (E) conversion factors for complete interventional procedures, based on in-the-field clinical measurements of DAP values and using tabulated E/DAP conversion factors for single projections available from the literature. Methods: Nine types of interventional procedures were performed on 84 patients with two angiographic systems. Different calibration curves (with and without patient table attenuation) were calculated for each DAP meter. Clinical and dosimetric parameters were recorded in-the-field for each projection and for all patients, and a conversion factor linking DAP and effective doses was derived for each complete procedure making use of published, Monte Carlo calculated conversion factors for single static projections. Results: Fluoroscopy time and DAP values for the lowest-dose procedure (biliary drainage) were approximately 3-fold and 13-fold lower, respectively, than those for the highest-dose examination (transjugular intrahepatic portosystemic shunt, TIPS). Median E/DAP conversion factors from 0.12 (abdominal percutaneous transluminal angioplasty) to 0.25 (Nephrostomy) mSvGy-1 cm-2 were obtained and good correlations between E and DAP were found for all procedures, with R2 coefficients ranging from 0.80 (abdominal angiography) to 0.99 (biliary stent insertion, Nephrostomy and TIPS). The DAP values obtained in this study showed general consistency with the values provided in the literature and median E values ranged from 4.0 mSv (biliary drainage) to 49.6 mSv (TIPS). Conclusions: Values of E/DAP conversion factors were derived for each procedure from a comprehensive analysis of projection and dosimetric data: they could provide a good evaluation for the stochastic effects. These results can be obtained by means of a close cooperation between different interventional professionals involved in patient care and dose optimization. \ua9 2012 American Association of Physicists in Medicine

Large regenerative nodules in a patient with Budd-Chiari syndrome after TIPS positioning while on the liver transplantation list diagnosed by Gd-EOB-DTPA MRI

BACKGROUND: Large regenerative nodules (LRNs) are hyperplastic benign nodules most commonly associated with Budd-Chiari syndrome (BCS), caused by outflow obstruction of the hepatic veins or vena cava. To our knowledge, no cases of LRNs arising in BCS after transjugular intrahepatic portosystemic shunt (TIPS) positioning and detected by Gd-EOB-DTPA MRI have been reported in the literature. METHODS: A 58-year-old woman with BCS, on the liver transplantation (LT) list, underwent a follow-up enhanced MRI. Two years earlier, a TIPS had been placed. In 2008, recurrent hepaticoencephalopathy resistant to medical treatment fulfilled the LT criteria for BCS treated with TIPS and the patient was therefore added to the LT list. CT performed before TIPS had not detected any hepatic lesions. CT performed six months after TIPS showed its complete patency but documented two indeterminate hypervascular liver lesions. RESULTS: MRI performed with Gd-EOB-DTPA revealed additional hypervascular lesions with uptake and retention of the medium in the hepatobiliary phase, thus reflecting a benign behavior of hepatocellular composition. These MRI features were related to LRNs as confirmed by histopathologic analysis. CONCLUSIONS: Gd-EOB-DTPA-enhanced MRI is potentially superior to standard imaging using gadolinium chelates or spiral CT, especially for the differential diagnosis of hypervascular lesions. Gd-EOB-DTPA MRI may become the imaging method of choice for evaluating LT list patients with BCS after TIPS placement

Intra-arterial chemotherapy of advanced pancreatic cancer: a single center experience

BACKGROUND/AIMS: The main aim of the present work was to determine response rates and time to progression in patients with locally advanced or metastatic pancreatic cancer treated with intra-arterial chemotherapy. METHODOLOGY: Nineteen chemotherapy-naive patients with measurable lesions were treated with intra-arterial 5-fluorouracil 1000 mg/m2, leucovorin 100 mg/m2, carboplatin 300 mg/m2 and epirubicin 60 mg/m2 (FLEC regimen) every 21 days. Prophylactic granulocyte colony-stimulating factors were administered on days 4-10 of each cycle. RESULTS: There were 16 patients evaluable for response, of whom 4 (25%) had a partial response, 7 (44%) showed stable disease, and 5 (31%) progressed. Marker response rate was 43%. Median time to progression was 4 months and median overall survival was 6 months. One-year overall survival was 16%. No grade 4 toxicity or severe complications relating to the angiographic procedure were observed. CONCLUSIONS: Our results show that intra-arterial FLEC is well tolerated and active against advanced pancreatic cancer
