Microsatellite Instability Is Insufficiently Used as a Biomarker for Lynch Syndrome Testing in Clinical Practice.

Purpose: The pan-cancer presence of microsatellite instability (MSI)-positive tumors demonstrates its clinical utility as an agnostic biomarker for identifying immunotherapy-eligible patients. Additionally, MSI is a hallmark of Lynch syndrome (LS), the most prevalent cancer susceptibility syndrome among patients with colorectal and endometrial cancer. Therefore, MSI-high results should inform germline genetic testing for cancer-predisposing genes.

Nutritional interventional studies in patients with multiple sclerosis: a scoping review of the current clinical evidence.

A good nutritional status appears to slow down disease progression and ameliorate symptoms' intensity in patients with multiple sclerosis (MS). Up to date, there are several interventional studies, which have explored the potential beneficial effects of specific dietary patterns as well as specific bioactive nutrients against disease progression and symptomatology of MS patients. This is a thorough, scoping review, which aims to critically summarize and scrutinize the currently available clinical evidence of the potential beneficial effects of nutritional interventional studies against MS progression and symptomatology.

High Filamin a Expression in Adrenocortical Carcinomas Is Associated with a Favourable Tumour Behaviour: A European Multicentric Study.

The insulin-like growth factor 2 (IGF2) promotes cell growth by overactivating the IGF system in an autocrine loop in adrenocortical carcinomas (ACCs). The cytoskeleton protein filamin A (FLNA) acts as a repressor of IGF2 mitogenic signalling in ACC cells. The aims of this study were to test FLNA expression by immunohistochemistry in 119 ACCs and 26 adrenocortical adenomas (ACAs) and to evaluate its relationship with clinicopathological features and outcome in ACCs.

Multivisceral Resection for Locally Advanced Gastric Cancer: A Systematic Review and Evidence Quality Assessment.

Patients with locally advanced gastric cancer (LAGC) often require multivisceral resection (MVR) of the involved organs to achieve R0 resection and local disease control. The aim of the present study was to systematically review all available literature on the postoperative and long-term outcomes of MVR for gastric cancer. The PubMed database was systematically searched by two independent investigators for studies concerning MVR for LAGC.

Genetic Characterization of Primary Mediastinal B-Cell Lymphoma: Pathogenesis and Patient Outcomes.

Purpose: Primary mediastinal large B-cell lymphoma (PMBCL) is a rare aggressive lymphoma predominantly affecting young female patients. Large-scale genomic investigations and genetic markers for risk stratification are lacking.

Patients And Methods: To elucidate the full spectrum of genomic alterations, samples from 340 patients with previously untreated PMBCL were investigated by whole-genome (n = 20), whole-exome (n = 78), and targeted (n = 308) sequencing.

Senescent cells in giant cell arteritis display an inflammatory phenotype participating in tissue injury via IL-6-dependent pathways.

Objectives: Age is the strongest risk factor of giant cell arteritis (GCA), implying a possible pathogenetic role of cellular senescence. To address this question, we applied an established senescence specific multimarker algorithm in temporal artery biopsies (TABs) of GCA patients.

Methods: 75(+) TABs from GCA patients, 22(-) TABs from polymyalgia rheumatica (PMR) patients and 10(-) TABs from non-GCA/non-PMR patients were retrospectively retrieved and analysed.

The impact of frailty and illness perceptions on quality of life among people living with HIV in Greece: A network analysis.

Objective: Despite the significant advances in healthcare, people living with HIV still face challenges that affect their quality of life (QoL), both in terms of their physical state as represented by frailty and of their illness perceptions (IP). The aim of this study was to unravel the associations between these constructs (QoL, frailty, IP).

Methods: This multicenter, cross-sectional study included 477 people living with HIV (93% male; median age = 43 years, IQR = 51.

Indirect Treatment Comparisons of Mosunetuzumab With Third- and Later-Line Treatments for Relapsed/Refractory Follicular Lymphoma.

Background: No established standard of care exists for relapsed/refractory (RR) follicular lymphoma (FL) after ≥2 prior therapies. We conducted indirect treatment comparisons (ITCs) to compare the efficacy and tolerability of mosunetuzumab with those of available treatments used in this setting.

Methods: A systematic literature review (SLR) and subsequent feasibility assessments were conducted to identify the most suitable comparator studies in terms of design, available endpoints and populations.

Adherence to Oral Nutrition Supplementation in Gastrointestinal Cancer Patients: A Systematic Review of the Literature.

The prevalence of malnutrition is high in gastrointestinal (GI) cancer patients. The use of oral nutrition supplementation (ONS) as part of patients' nutritional therapy seems to be effective in the improvement of nutritional status. Nevertheless, oncology patients, experience several symptoms that negatively affect their compliance with ONS products.

A short history of mediastinal tumours.

The mediastinum constitutes an area of special surgical interest due to important anatomical relationships and histopathologic variability of mediastinal primary and metastatic tumours. Mediastinum was considered inaccessible until the end of the 19 century. For many decades the diagnosis of mediastinal disease relied solely upon clinical presentation, and the mainstay of treatment was medical therapy.

Modified pericostal suture technique to reduce postoperative pain and provide optimum anatomic restoration after conversion of minimally invasive thoracic surgery to thoracotomy.

Minimally invasive thoracic techniques often need to be converted to open thoracotomy. Thoracotomy is associated with severe postoperative pain in 50% of the patients, and this situation can be maintained for a prolonged period. Many efforts have been made to avoid this complication.

The Impact of Trophoblast Cell-Surface Antigen 2 Expression on the Survival of Patients with Gastrointestinal Tumors: A Systematic Review.
