In therapeutic trials the use of manipulated cell cultures for clinical applications is often required. Mollicutes microorganism contamination of tissue cultures is a major problem because it can determine various and severe alterations in cellular function. Thus methods able to detect and trace cell cultures with Mollicutes contamination are...

Immunotherapies have changed the treatment strategy of some types of tumor including melanoma and, more recently, non-small-cell lung cancer (NSCLC). Immune checkpoints are crucial for the maintenance of self-tolerance and it is known that some tumors use checkpoint systems to evade antitumor immune response. The treatment of advanced NSCLC by...

Specific combinations of killer immunoglobulin-like receptors (KIR) and human leukocyte antigen (HLA) class I molecules characterized by a particular residue 80 are significantly associated with outcomes in different pathologic conditions, such as autoimmunity, pathogenic infection, cancer, and reproductive failure. Thus, a simplified method...

Circulating exosomes are the major mediators of cell–cell communication. They have been found in various body fluids of healthy individuals and patients with malignancies as cargos of several molecules including miRNAs. Several studies have underlined the role of exosome miRNAs in different tumor types, including lung cancer, suggesting their...

The incidence of melanoma, among the most lethal cancers, is widespread and increasing. Metastatic melanoma has a poor prognosis, representing about 90% of skin cancer mortality. The increased knowledge of tumor biology and the greater understanding of the immune system role in the anti-tumor response has allowed us to develop a more rational...

Background aims. The clinical applications of in vitro manipulated cultured cells and their precursors are often made use of in therapeutic trials. However, tissue cultures can be easily contaminated by the ubiquitous Mollicutes micro-organisms, which can cause various and severe alterations in cellular function. Thus methods able to detect and...

Quantitative real-time PCR (qPCR) has been improved and optimized over the past decade for a wide range of applications. Design of primers and probes is one of the crucial steps to obtain high system efficiency of qPCR since design pitfalls influence negatively amplification performances. We report the results of some experiments. First, we...

Incidence of melanoma has been constantly growing during the last decades. Although most of the new diagnoses are represented by thin melanomas, the number of melanoma-related deaths in 2018 was 60,712 worldwide (Global Cancer Observatory, 2019). Until 2011, no systemic therapy showed to improve survival in patients with advanced or metastatic...

Meticillin-resistant Staphylococcus aureus (MRSA) is one of the leading causes of hospital-associated infections. This study investigated the potential use of whole-genome sequencing (WGS) for surveillance purposes by re-examining MRSA strains related to past outbreaks among hospitalized paediatric patients. WGS data ameliorated the genotypic...

Melanoma is one of the most aggressive tumors of the skin, and its incidence is growing worldwide. Historically considered a drug resistant disease, since 2011 the therapeutic landscape of melanoma has radically changed. Indeed, the improved knowledge of the immune system and its interactions with the tumor, and the ever more thorough molecular...

Introduction: Although the achievements in the treatment of advanced non-small cell lung cancer (NSCLC) have been translated in improved disease control, response rate and survival, especially in the case of patients with targetable oncogenic drivers, acquired resistance is common after initial benefit; furthermore, primary resistance can...

Circulating tumor cells (CTCs) are cells spread from the primary tumor into the bloodstream that might represent an important biomarker in lung cancer. The prognosis of patients diagnosed with lung cancer is generally poor mainly due to late diagnosis. Recent evidences have reported that tumor aggressiveness is associated with the presence of...

Introduction: Vinflunine belongs to the class of vinca alkaloids and acts by disrupting the microtubule dynamics during cell cycle; this agent is currently available for previously treated advanced transitional cell carcinoma in Europe. The aim of this invited review is to evaluate the potential role of vinflunine for the treatment of non-small...

Background: Human cytomegalovirus (HCMV) is an opportunistic pathogen especially for immuno-suppressed subjects that might develop pharmacological resistance in patients undergoing prolonged antiviral treatment. Ganciclovir (GCV) is the drug used as first choice therapy in affected children and a GCV-resistant phenotype is mainly linked to...

Malignant Pleural Mesothelioma (MPM) is an aggressive disease characterized by a dismal prognosis, mainly due to late diagnosis. To date, there are very few treatment options available and the refractoriness to the majority of therapeutic strategies, leading to consider MPM a relevant problem in public health. Therefore, the identification of...

A growing body of evidence links the analysis of the KIR genotype and the presence of their HLA-B and -C ligands to a wide repertoire of human diseases.We noticed that, using a panel of 184 Caucasoid donors, a limited number of HLA alleles were incorrectly supratyped by previously described pyrosequence-based assays. Here we describe a simple...

Introduction: Fibroblast growth factor receptor (FGFR) due to its central role in regulating cell survival, is a promising target for cancer therapeutics. Dysregulation of the FGFR pathway has been observed in several malignancies, including non-small cell lung cancer (NSCLC) particularly in patients with squamous histology. Areas covered: The...

Background: Next Generation Sequencing (NGS) has become a valuable tool for molecular landscape characterization of cancer genomes, leading to a better understanding of tumor onset and progression, and opening new avenues in translational oncology. Formalin-fixed paraffin-embedded (FFPE) tissue is the method of choice for storage of clinical...

Introduction: Tyrosine kinase inhibitors (TKI) are currently the most effective therapy for patients with NSCLC and common activating mutations of EGFR. Afatinib, an irreversible EGFR, HER2, and HER4 inhibitor, has recently been approved at the dose of 40 mg daily as front-line treatment for advanced NSCLC with common EGFR-activating...

Immune checkpoint blockade represents a major breakthrough in advanced non-small cell lung cancer (NSCLC) therapy. However, success is limited to a subset of patients and there is a critical need to identify robust biomarkers associated with clinical response. In this study, we assessed whether pre-existing immunological characteristics, as...

Cell-free DNA (cfDNA) and circulating tumor cells (CTCs) are promising prognostic and predictive biomarkers in non-small cell lung cancer (NSCLC). In this study, we examined the prognostic role of cfDNA and CTCs, in separate and joint analyses, in NSCLC patients receiving first line chemotherapy. Seventy-three patients with advanced NSCLC were...
