RNA-Based Next-Generation Sequencing in Non-Small Cell Lung Cancer patients: data from Campania, Italy.

Objective: ALK, ROS1, NTRK, and RET gene fusions and MET exon 14 skipping alterations represent fundamental predictive biomarkers for advanced non-small cell lung cancer (NSCLC) patients to ensure the best treatment choice. In this scenario, RNA-based NGS approach has emerged as an extremely useful tool for detecting these alterations. In this study, we report our NGS molecular records on ALK, ROS1, NTRK, and RET gene fusions and MET exon 14 skipping alterations detected by using a narrow RNA-based NGS panel, namely SiRe fusion.

Intestinal and Extraintestinal Findings of Graft-versus-Host Disease on CT: A Case Series with Radiological and Histopathological Correlations.

Graft-versus-host disease (GVHD) is an expected and relatively common complication after allogeneic hematopoietic stem cell transplantation. It may affect different organs and typically involves the skin, liver, and gastrointestinal tract (GI-GVHD). GI-GVHD may show heterogeneous presentations with peculiar diagnostic implications.

Prognosis of Adrenal Oncocytic Neoplasms (AONs): Literature Review of 287 Cases and Presentation of the Oldest Patient.

Introduction: The adrenocortical oncocytic neoplasms (AONs) are rare tumors of the adrenal gland, classified as oncocytoma (AO), oncocytic neoplasm of uncertain malignant potential (AONUMP) and oncocytic carcinoma (AOC). The aim of this study was to perform a review of the literature, in order to evaluate the prognosis of these rare cancers. We also reported the oldest patient with AON.

Evaluation of BRAF, RAS, RET/PTC, and PAX8/PPARg alterations in different Bethesda diagnostic categories: A multicentric prospective study on the validity of the 7-gene panel test in 1172 thyroid FNAs deriving from different hospitals in South Italy.

Background: Thyroid fine-needle aspiration (FNA) is a reliable and cost-effective diagnostic tool for establishing the nature of thyroid nodules, although up to 30% of FNAs are still classified as "indeterminate." Molecular testing of FNAs could improve preoperative diagnosis, thereby reducing unnecessary surgery. In this multicenter prospective study the authors investigated, using a 7-gene assay, the distribution and diagnostic impact of BRAF, RAS, RET/PTC, and PAX8/PPARg, the most frequent genomic alterations occurring during thyroid oncogenesis.

IBD: Role of intestinal compartments in the mucosal immune response.

Background And Aims: Laser capture microdissection (LCM) is a powerful tool for the isolation of specific tissue compartments. We aimed to investigate the mucosal immune response that takes place in different intestinal compartments of IBD patients, dissected by LCM, analyzing cytokines expression profile and endoplasmic reticulum (ER) stress markers.

Methods: Frozen sections of gut were obtained from patients with Crohn's disease (CD), ulcerative colitis (UC) and from controls.

Endocrinopathies induced by immune-checkpoint inhibitors in advanced non-small cell lung cancer.

The advent of immunotherapy has recently expanded the therapeutic options in advanced non-small cell lung cancer (NSCLC). In these patients, the recent efficacy demonstration of antibodies against immune checkpoints: the anti-programmed death-1 (PD-1) and anti-programmed death ligand-1 (PD-L1), has led to approval of nivolumab and pembrolizumab (anti-PD-1) in the treatment of advanced NSCLC. The mechanism of action of checkpoint inhibitors explains the development of autoimmune diseases as a side-effect of these medications.

Treatment of pulmonary neuroendocrine tumours: state of the art and future developments.

The current classification of pulmonary neuroendocrine tumours includes four subtypes: low-grade typical carcinoid tumour (TC), intermediate-grade atypical carcinoid tumour (AC), and two high-grade malignancies: large cell neuroendocrine carcinoma and small cell lung cancer (SCLC). Unfortunately, with the exclusion of SCLC, no large phase II and III trials for pulmonary neuroendocrine tumours have been published. Thus, several treatment approaches are available for their treatment but none of them has been validated in appropriately designed and adequately sized clinical trials.

Validation of an extension of the international non-invasive criteria for the diagnosis of hepatocellular carcinoma to the characterization of macroscopic portal vein thrombosis.

Background And Aim: We aimed to validate the non-invasive criteria for the characterization of portal vein thrombosis (PVT) in patients with cirrhosis and hepatocellular carcinoma (HCC). In a prospective study, we examined the impact of arterial hypervascularity, as established by the European Association for the Study of the Liver and the American Association for the Study of Liver Diseases recommendations for the non-invasive diagnosis of HCC, as a criterion for characterizing macroscopic PVT (EASL/AASLD extension criteria).

Methods: A total of 96 cases of PVT detected using ultrasonography in patients with cirrhosis and HCC were included in the study.

Oxidative stress and steatosis are cofactors of liver injury in primary biliary cirrhosis.

Background: Factors responsible for the progression of primary biliary cirrhosis (PBC) are still poorly understood. In the present study, we investigated the associations between the stage of PBC and the immune reaction triggered by oxidative stress; the presence of obesity, steatosis,steatohepatitis; and other toxic, metabolic, or steatogenic factors.

Methods: We studied clinical, laboratory, and histological data for 274 untreated patients with serum antimitochondrial antibody (AMA)-positive PBC.

Low-energy interstitial laser photocoagulation for treatment of nonfunctioning thyroid nodules: therapeutic outcome in relation to pretreatment and treatment parameters.

Objective: Interstitial laser photocoagulation (ILP) is a recently proposed therapeutic procedure for the ablation of benign thyroid nodules, which has already proven to be safe and effective. However, results supporting the routine use of ILP are still limited.

Design: The aim of the study was to evaluate the efficacy and safety of ILP treatment in benign nonfunctioning thyroid nodules and to establish whether the therapeutic outcome may be predicted by any clinical parameter at baseline.

Complete response of severe symptomatic bone marrow metastases from heavily pretreated breast cancer with a 3-weekly trastuzumab schedule. A clinical case.

Overexpression of HER-2/neu in breast cancer has been associated with more aggressive disease and poor overall survival. Trastuzumab, a recombinant humanized monoclonal antibody with high affinity for the HER-2 protein, inhibits the growth of breast cancer cells overexpressing HER-2. Trastuzumab showed, as second-line treatment, 15% of objective response in metastatic breast cancer.
