Extracellular Vesicles Derived from Mesenchymal Stromal Cells Delivered during Hypothermic Oxygenated Machine Perfusion Repair Ischemic/Reperfusion Damage of Kidneys from Extended Criteria Donors.

The poor availability of kidney for transplantation has led to a search for new strategies to increase the donor pool. The main option is the use of organs from extended criteria donors. We evaluated the effects of hypothermic oxygenated perfusion (HOPE) with and without extracellular vesicles (EV) derived from mesenchymal stromal cells on ischemic/reperfusion injury of marginal kidneys unsuitable for transplantation.

Everolimus plus aromatase inhibitors as maintenance therapy after first-line chemotherapy: Final results of the phase III randomised MAIN-A (MAINtenance Afinitor) trial.

Background: Despite endocrine therapy being the mainstay of treatment for hormone receptor positive (HR+)/HER2- metastatic breast cancer, patients at risk of visceral crisis or doubt for endocrine sensitivity are still offered first-line chemotherapy. Maintenance hormonal therapy is generally offered at the discontinuation of chemotherapy. The MAINtenance Afinitor study is a randomised, phase III trial comparing maintenance everolimus combined with aromatase inhibitors (AIs) versus AI monotherapy in patients with disease control after first-line chemotherapy.

Baseline Histological Findings Do Not Predict the Risk of Subsequent Extension in Patients with Limited Ulcerative Colitis.

Background: Among patients with limited ulcerative colitis (UC), 30% ultimately extend to pancolitis and are at increased risk of adverse clinical outcomes. Risk of endoscopic extension has been found to correlate with clinical features such as early age of onset.

Aims: We sought to determine whether histologic features correlate with disease extension.

Loss of HER2 and decreased T-DM1 efficacy in HER2 positive advanced breast cancer treated with dual HER2 blockade: the SePHER Study.

Background: HER2-targeting agents have dramatically changed the therapeutic landscape of HER2+ advanced breast cancer (ABC). Within a short time frame, the rapid introduction of new therapeutics has led to the approval of pertuzumab combined with trastuzumab and a taxane in first-line, and trastuzumab emtansine (T-DM1) in second-line. Thereby, evidence of T-DM1 efficacy following trastuzumab/pertuzumab combination is limited, with data from some retrospective reports suggesting lower activity.

Prognostic and predictive factors to nivolumab in patients with metastatic renal cell carcinoma: a single center study.

Renal cell carcinoma (RCC) scenario has radically changed with the advent of immunotherapy; in this setting, the identification of predictive and prognostic factors represents an urgent clinical need to evaluate which patients are the best candidate for an immunotherapy approach. The aim of our study was to analyze the association between nivolumab in pretreated patients with metastatic RCC and clinicopathological features, metastatic sites, and clinical outcomes. A total of 37 patients treated between January 2017 and April 2020 in our institution were retrospectively evaluated.

Comparison of Sequential Testing and Next Generation Sequencing in advanced Lung Adenocarcinoma patients - A single centre experience.

Objectives: Molecular diagnosis determines therapeutic strategies for patients with non-small-cell lung cancer - adenocarcinoma (NSCLC-A) but depends on resources availability. We compared a sequential single-gene testing algorithm to next generation sequencing in NSCLC-A to assess differences in terms of effectiveness, costs, tissue consumption and time.

Materials And Methods: We analyzed a retrospective cohort of advanced NSCLC-A patients treated at the Sant'Orsola-Malpighi University Hospital.

Periostin, tenascin, osteopontin isoforms in long- and non-long survival patients with pancreatic cancer: a pilot study.

Pancreatic adenocarcinoma (PDAC) is the most frequent histological type of malignancy in the pancreas. Extracellular matrix (ECM), plays a critical role during the process of human carcinogenesis and the possible diversity in matricellular proteins composition of ECM may have a significant impact on the clinical course of PDAC. Aim of this paper was to evaluate the expression of three matricellular proteins, including Periostin (POSTN), Tenascin (TNS) and Osteopontin (OPN), in PDAC from long-survival (LS) and non-long survival (NLS) patients.

Combination therapy in advanced urothelial cancer: the role of PARP, HER-2 and mTOR inhibitors.

Introduction: Despite significant advances in the treatment of metastatic urothelial carcinoma, including the advent of immune checkpoint inhibitors, this disease is still challenging to treat and associated poor outcomes remain. Genomic characterization of advanced-stage urothelial carcinoma is widening the field of potential treatments due to the identification of novel biologic drivers.

Areas Covered: In this review, we explore the role of PARP, HER-2, and mTOR inhibitors in the therapeutic scenario of advanced urothelial carcinoma, as these pathways are frequently altered in urothelial carcinoma.

Current Strategies and Novel Therapeutic Approaches for Metastatic Urothelial Carcinoma.

Urothelial carcinoma (UC) is a frequent cause of cancer-related deaths worldwide. Metastatic UC has been historically associated with poor prognosis, with a median overall survival of approximately 15 months and a 5-year survival rate of 18%. Although platinum-based chemotherapy remains the mainstay of medical treatment for patients with metastatic UC, chemotherapy clinical trials produced modest benefit with short-lived, disappointing responses.

Detection of EGFR-Activating and T790M Mutations Using Liquid Biopsy in Patients With EGFR-Mutated Non-Small-Cell Lung Cancer Whose Disease Has Progressed During Treatment With First- and Second-Generation Tyrosine Kinase Inhibitors: A Multicenter Real-Life Retrospective Study.

Background: In advanced epidermal growth factor receptor (EGFR)-mutated non-small-cell lung cancer (NSCLC) patients whose disease has progressed during treatment with first- and second-generation tyrosine kinase inhibitors (TKIs), liquid biopsy (LB) is routinely used to evaluate the presence of EGFR T790M as an acquired resistance mechanism. The objective of this study was to assess a real-life picture of EGFR T790M detection in LB.

Materials And Methods: Liquid biopsies performed between June 2016 and October 2018 for advanced EGFR-mutated NSCLC at disease progression during treatment with first- and second-generation TKIs were retrospectively evaluated in 5 Italian centers.

Impact of BMI on HER2+ metastatic breast cancer patients treated with pertuzumab and/or trastuzumab emtansine. Real-world evidence.

Body mass index (BMI) is a main indicator of obesity and its association with breast cancer is well established. However, little is known in the metastatic setting, especially in HER2-positive patients. We assessed the influence of BMI on clinical outcomes of patients treated with pertuzumab and/or trastuzumab emtansine (T-DM1) for HER2+ metastatic breast cancer (mBC).

Improving IMDC Prognostic Prediction Through Evaluation of Initial Site of Metastasis in Patients With Metastatic Renal Cell Carcinoma.

Background: Several models are adopted in clinical practice to estimate prognosis of patients with metastatic renal cell carcinoma (mRCC); however, none of these models have evaluated patients treated by immune-checkpoint inhibitors. The aim of this study was to investigate if the site of initial metastasis could be a parameter able to stratified prognosis among patients with mRCC among different risk groups defined by the International Metastatic Renal Cell Database Consortium (IMDC) model. The site of initial metastasis was defined as the primary tissue or organ in which metastasis was diagnosed in the course of the medical history of the disease.

A Prospective Study of Intraprostatic Inflammation, Focal Atrophy, and Progression to Lethal Prostate Cancer.

Background: Inflammation and focal atrophy are common features adjacent to prostate tumors. Limited evidence exists on whether these features have prognostic significance.

Methods: In the Health Professionals Follow-Up Study and Physicians' Health Study, we studied 1,035 men diagnosed with prostate cancer.

A Meta-Analysis Evaluating Clinical Outcomes of Patients with Renal Cell Carcinoma Harboring Chromosome 9P Loss.

Context: 9p loss appears a reliable and promising marker able to differentiate specific categories of patients with renal cell carcinoma associated with a worse prognosis.

Objective: The aim was to systematically evaluate relative risk of death, cancer-specific survival (CSS) and disease-free survival (DFS) among patients harboring 9p loss.

Evidence Synthesis: We found a total of 92 potentially relevant articles focused on the detection of 9p loss in patients with renal cell carcinoma and clinical outcomes of this population.

Distinct HR expression patterns significantly affect the clinical behavior of metastatic HER2+ breast cancer and degree of benefit from novel anti-HER2 agents in the real world setting.

We analyzed data from 738 HER2-positive metastatic breast cancer (mbc) patients treated with pertuzumab-based regimens and/or T-DM1 at 45 Italian centers. Outcomes were explored in relation to tumor subtype assessed by immunohistochemistry (IHC). The median progression-free survival at first-line (mPFS1) was 12 months.

BAP1 in solid tumors.

One of the most attractive cancer-related genes under investigation is BAP1. Reasons of this growing interest are related to the wide spectrum of pathways directly or indirectly modulated by this gene and shared by several solid tumors. Programmed cell-death, cell metabolisms, immune cells development, ferroptosis and defects in DNA damage response are only some of the multitude of processes depending on BAP1.

Patterns of positive surgical margins after open radical prostatectomy and their association with clinical recurrence.

Background: We report long-term oncologic outcomes in patients with positive surgical margins (PSMs) at radical prostatectomy (RP) and the oncologic impact of different scenarios of PSMs presentation.

Methods: We selected 494 men with at least 3 years follow-up after surgery. PSMs patterns were recorded as: burden (focal vs.

PD-L1 Expression is Associated With Poor Prognosis in Renal Cell Carcinoma.

Programmed death ligand 1 (PD-L1) is a protein which, when interacting with its receptor programmed death 1, acts as a negative regulator of the antitumor T-cell-mediated immune response. The prognostic value of PD-L1 expression in renal cell carcinoma (RCC) has been controversial. In this study, the prognostic value of PD-L1 expression in RCC was evaluated by analyzing PD-L1 immunoreactivity in tumor cells and tumor-infiltrating immune cells (TIICs) in 346 RCC patients with long-term follow-up.

PD-L1 Expression in Men with Penile Cancer and its Association with Clinical Outcomes.

Background: It has been hypothesized that PD-L1 expression in tumor cells and tumor-infiltrating immune (TII) cells may contribute to tumor progression by inhibiting antitumor immunity.

Objective: To investigate the association between PD-L1 expression in tumor cells and TII cells and clinical outcomes in penile cancer.

Design, Setting, And Participants: A cohort of 222 men treated for penile squamous cell carcinoma (SqCC) at Örebro University Hospital between 1984 and 2008 with long-term follow-up (median 34 mo) was evaluated for PD-L1 expression in tumor cells and TII cells via immunohistochemistry.

Estimation of Relative and Absolute Risks in a Competing-Risks Setting Using a Nested Case-Control Study Design: Example From the ProMort Study.

In this paper, we describe the Prognostic Factors for Mortality in Prostate Cancer (ProMort) study and use it to demonstrate how the weighted likelihood method can be used in nested case-control studies to estimate both relative and absolute risks in the competing-risks setting. ProMort is a case-control study nested within the National Prostate Cancer Register (NPCR) of Sweden, comprising 1,710 men diagnosed with low- or intermediate-risk prostate cancer between 1998 and 2011 who died from prostate cancer (cases) and 1,710 matched controls. Cause-specific hazard ratios and cumulative incidence functions (CIFs) for prostate cancer death were estimated in ProMort using weighted flexible parametric models and compared with the corresponding estimates from the NPCR cohort.
