Cylindrical TGR as early radiological predictor of RLT progression in GEPNETs: a proof of concept.

This study aims to assess the predictive capability of cylindrical Tumor Growth Rate (cTGR) in the prediction of early progression of well-differentiated gastro-entero-pancreatic tumours after Radio Ligand Therapy (RLT), compared to the conventional TGR. Fifty-eight patients were included and three CT scans per patient were collected at baseline, during RLT, and follow-up. RLT response, evaluated at follow-up according to RECIST 1.

Stability of Multi-Parametric Prostate MRI Radiomic Features to Variations in Segmentation.

Stability analysis remains a fundamental step in developing a successful imaging biomarker to personalize oncological strategies. This study proposes an in silico contour generation method for simulating segmentation variations to identify stable radiomic features. Ground-truth annotation provided for the whole prostate gland on the multi-parametric MRI sequences (T2w, ADC, and SUB-DCE) were perturbed to mimic segmentation differences observed among human annotators.

Textbook Outcome After Trans-arterial Chemoembolization for Hepatocellular Carcinoma.

Purpose: Textbook Outcome (TO) is inclusive of quality indicators and it not been provided for trans-arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC).

Materials And Methods: Data 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.

A "blood theft" after liver transplantation: the role of interventional radiology in the management and treatment of splenic artery steal syndrome.

Splenic artery steal syndrome is a rare complication after liver transplant. It could lead to rapidly evolving major issues such as ischemic cholangiopathy and acute graft failure. Although the pathophysiology is not yet well understood, if diagnosed in time it could be easily managed with interventional radiology treatments.

Long Term Survival Analysis in a Cohort of 125 Patients with Hepatocellular Carcinoma Treated with Transarterial Chemoembolization Using Small Drug Eluting Beads.

Purpose: Different types of drug-eluting beads have been proposed for hepatocellular carcinoma (HCC) treatment, but long-term results are not well known. We report safety, efficacy and long-term overall survival of HCC patients not amenable of curative therapies treated with transcatheter arterial chemoembolization (TACE) using drug-eluting beads sized 70-150 micron.

Materials And Methods: This single-center retrospective study included 125 patients with Barcelona Clinic Liver Cancer stage A (80), B (45) and compensated cirrhosis.

Application of FLIC model to predict adverse events onset in neuroendocrine tumors treated with PRRT.

To develop predictive models of side effect occurrence in GEPNET treated with PRRT. Metastatic GEPNETs patients treated in our centre with PRRT (177Lu-Oxodotreotide) from 2019 to 2020 were considered. Haematological, liver and renal toxicities were collected and graded according to CTCAE v5.

Inter-center agreement of mRECIST in transplanted patients for hepatocellular carcinoma.

Objectives: To evaluate the inter-observer reliability of modified Response Evaluation Criteria In Solid Tumours (mRECIST) of patients with hepatocellular carcinoma (HCC) undergoing neo-adjuvant treatments before liver transplant (LT). The agreement of tumor number, size, transplant criteria, and the radiological-pathological concordance were also assessed.

Methods: A total of 180 radiological studies before/after neo-adjuvant therapies performed on 90 patients prior to LT were reviewed from three expert centers.

MRI based radiomics in nasopharyngeal cancer: Systematic review and perspectives using radiomic quality score (RQS) assessment.

Background: MRI based radiomics has the potential to better define tumor biology compared to qualitative MRI assessment and support decisions in patients affected by nasopharyngeal carcinoma. Aim of this review was to systematically evaluate the methodological quality of studies using MRI- radiomics for nasopharyngeal cancer patient evaluation.

Methods: A systematic search was performed in PUBMED, WEB OF SCIENCE and SCOPUS using "MRI, magnetic resonance imaging, radiomic, texture analysis, nasopharyngeal carcinoma, nasopharyngeal cancer" in all possible combinations.

Sarcoidosis-like disease mimicking metastases during adjuvant ipilimumab therapy in advanced melanoma patient: CT scan and MRI help in managing difficult clinical decision.

The onset of an autoimmune, sarcoidosis-like reaction during or after treatment with immunomodulatory drugs as Ipilimumab is an atypical but renowned eventuality. Awareness of this scenario and its radiological features helps the Radiologist to avoid misdiagnosis of disease progression. In this case report, we present a patient operated for advanced cutaneous melanoma of the left forearm who developed hilar adenopathies with lung and splenic nodules during therapy with Ipilimumab in adjuvant setting.

Including mRECIST in the Metroticket 2.0 criteria improves prediction of hepatocellular carcinoma-related death after liver transplant.

Background & Aims: In the context of liver transplantation (LT) for hepatocellular carcinoma (HCC), prediction models are used to ensure that the risk of post-LT recurrence is acceptably low. However, the weighting that 'response to neoadjuvant therapies' should have in such models remains unclear. Herein, we aimed to incorporate radiological response into the Metroticket 2.

Percutaneous microwave ablation therapy of renal cancer local relapse after radical nephrectomy: a feasibility and efficacy study.

Renal cell carcinoma (RCC) local recurrence after radical nephrectomy is uncommon. When feasible, surgical removal remains the primary treatment strategy; nevertheless, local RCC relapse management is controversial, and less invasive procedures may represent an attractive option to achieve oncologic control. The aim of our study was to assess the feasibility, safety, and clinical outcomes of image-guided percutaneous microwave ablation (MWA) for RCC local recurrence in patients initially treated with nephrectomy with curative intent.

Percutaneous cervical discectomy: retrospective comparison of two different techniques.

Aim: To compare clinical success and patient satisfaction of percutaneous cervical nucleoplasty (PCN) and percutaneous cervical discectomy (PCD) in contained cervical disc herniation treatment.

Materials And Methods: We retrospectively identified 50 consecutive patients in our institution: 24 underwent the PCD treatment and 26 patients were treated by the PCN procedure. All patients complained of radicular pain with or without neck pain; diagnosis of contained cervical disc herniation was obtained by MRI; all patients had received conservative therapy which did not result in symptom improvement.

Percutaneous microwave ablation of uterine fibroids: correlation between shrinkage and trend symptoms.

Purpose: To assess a correlation between the shrinkage of the fibroid and the course of the symptoms.

Material And Methods: Fourteen patients with symptomatic uterine leiomyomas (mean fibroid volume: 111.45 cm) underwent percutaneous microwave ablation.

Somatostatin analogs in association with peptide receptor radionucleotide therapy in advanced well-differentiated NETs.

Data from 69 well-differentiated gastroenteropancreatic neuroendocrine tumors treated with peptide receptor radionucleotide therapy + somatostatin analogs (SSAs) after SSA treatment failure were evaluated. We identified two groups: S1 - patients who kept the same SSA treatment beyond progression; S2 - patients who switched the SSA with another SSA after progression. Median progression-free survival was 53 and 127 months in S1 and S2, respectively (p = 0.

Safety profile and treatment response of everolimus in different solid tumors: an observational study.

Aim: Only few efforts have been taken to investigate the potential existence of disease-specific differences in the safety profile of everolimus. We analyze here the correlation between different patient and tumor characteristics on the safety profile of this molecule. Information on treatment response is also provided.

Targeted treatments in advanced renal cell carcinoma: focus on axitinib.

Antiangiogenesis options have evolved rapidly in the last few years, with an increasing number of agents currently approved by the US Food and Drug Administration and European Medicines Agency. Angiogenesis inhibitors have been shown to be very effective for the treatment of metastatic renal cancer cell. Axitinib is a third-generation inhibitor of vascular endothelial growth factor receptor and is currently being developed for the treatment of various malignancies.

Rationale and protocol of RESORT, a randomized, open-label, multicenter phase II study to evaluate the efficacy of sorafenib in patients with advanced renal cell carcinoma after radical resection of the metastases.

The introduction of targeted agents did not totally resolve the approach to the treatment of metastatic renal cell carcinoma (mRCC) because complete response is rarely achieved. Recent findings seem to indicate that metastasectomy may improve survival. The RESORT study was designed to evaluate the additional clinical benefit of metastasectomy followed by sorafenib in a population of mRCC patients.
