Vaccine and immune cell therapy in non-small cell lung cancer
2018
Abstract: Despite new advances in therapeutics, lung cancer remains the first cause of mortality among different types of malignancies. To improve survival, different strategies have been developed such as chemotherapy combinations, targeted therapies and more recently immunotherapy. Immunotherapy is based on the capability of the immune system to differentiate cancer cells from normal cells to fight against the tumor. The two main checkpoint inhibitors that have been widely studied in non-small cell lung cancer (NSCLC) are PD-1/PD-L1 and CTLA-4. However, interactions between tumor and immune system are much more complex with several different elements that take part and probably many new i…
Numerical, dimensional or mixed progression disease to imatinib as prognostic factor in patients with metastatic GIST.
2017
11040 Background: The majority of GIST patients with advanced disease initially achieves disease control from imatinib treatment. Approximately 10% of patients progresses within 6 months of starting therapy (primary resistance) and also 50-60% of the responding patients develops progression disease within two years (secondary resistance). Progression disease (PD) can be numerical, dimensional or mixed. The known prognostic factors of risk stratification in local disease are tumor size, mitotic activity and anatomic site. In this retrospective analysis we explore several clinical factors affecting survival in metastatic setting. Methods: The population included in this large database of 128…
Are erlotinib and gefitinib interchangeable, opposite or complementary for non-small cell lung cancer treatment? Biological, pharmacological and clin…
2014
Abstract: Gefitinib and erlotinib are the two anti-epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) approved for treatment of advanced NSCLC patients. These drugs target one of the most important pathways in lung carcinogenesis and are able to exploit the phenomenon of 'oncogene addiction', with different efficacy according to EGFR gene mutational status in tumor samples. Gefitinib has been approved only for EGFR mutation bearing patients regardless the line of treatment, while erlotinib is also indicated in patients without EGFR mutation who undergo second- or third-line treatment. Some studies evaluated the main differences between these drugs both for direct comp…
Metastatic site location influences the diagnostic accuracy of ctDNA EGFR- mutation testing in NSCLC patients: a pooled analysis
2018
Background: Recent studies evaluated the diagnostic accuracy of circulating tumor DNA (ctDNA) analysis in the detection of epidermal growth factor receptor (EGFR) mutations from plasma of NSCLC patients, overall showing a high concordance as compared to standard tissue genotyping. However it is less clear if the location of metastatic site may influence the ability to identify EGFR mutations. Objective: This pooled analysis aims to evaluate the association between the metastatic site location and the sensitivity of ctDNA analysis in detecting EGFR mutations in NSCLC patients. Methods: Data from all published studies, evaluating the sensitivity of plasma-based EGFRmutation testing, stratifi…

Finally, sunitinib and everolimus, have been approved for the treatment of the neuroendocrine gastroenteropancreatic tumors. Actually a great number of further drugs are under preclinic…
Neuroendocrine Neoplasms (NENs)
2021
Neuroendocrine neoplasms (NENs) represent a rare and heterogeneous group of malignancies which can develop in many different sites of our body. They originate from the cells of the diffuse neuroendocrine system. Gastroenteropancreatic NENs were classified in four categories, including NETs G1 (WD with 20% Ki-67), and NECs (PD with >20% Ki-67) in accordance with the 2019 WHO classification (IARC WHO Classification of the digestive system tumors, on 11th July 2019). Lung NENs, in accordance with the latest WHO classification, 2015 edition, are distinguished in small cell lung cancer (SCLC), large cell neuroendocrine carcinoma (LCNEC), atypical carcinoid (AC), and typical carcinoid (TC).
Ramucirumab and its use in gastric cancer treatment
2014
Abstract: The inhibition of the mechanisms of tumor neo-angiogenesis represents a milestone that in the last 10 years has seen the advent of numerous molecules to target action against the vascular endothelial growth factor (VEGF). More recently, new molecules have been developed that inhibit tumor spread by the blockade of specific VEGF receptors (VEGFRs), thereby preventing the binding of a ligand to its receptor and the cascade of proliferative events downstream. Ramucirumab is a fully humanized IgG1 monoclonal antibody that performs its action by blocking the isoform 2 of the VEGF receptor (VEGFR-2). Numerous preclinical and clinical studies have demonstrated its activity in several sol…
Management of Toxicity Induced by Anti-EGFR Therapy in Metastatic Colorectal Cancer
2013
Use of anti-epidermal growth factor receptor (anti-EGFR) agents has yielded significant advances in the treatment of patients with metastatic colorectal cancer. In fact these drugs, which include the monoclonal antibodies cetuximab and panitumumab, can be delivered both as a single agent and in combination with chemotherapy, achieving better survival and quality of life and in some cases also resectability of metastases. However, these agents can result in the development of toxicities that are usually different from those observed with chemotherapy alone. For the management of these adverse effects, proper knowledge is mandatory. Skin toxicity is the most frequent adverse effect. Other tox…
Immune-checkpoint inhibitors in non-small cell lung cancer: A tool to improve patients’ selection
2018
The identification of reliable predictive biomarkers of efficacy or resistance to immune-oncology (I–O) agents is a major issue for translational research and clinical practice. However, along with PDL1 and molecular features other clinical, radiological and laboratory factors can be considered for the selection of those patients who would not be the best candidate for immune-checkpoint inhibitors (ICPIs). We examined these factors, emerging from the results of currently available studies in non-small cell lung cancer (NSCLC), aiming to provide a useful and manageable tool which can help Oncologists in their everyday clinical practice. A thorough patient evaluation and close clinical monito…
Cardiotoxicity mechanisms of the combination of BRAF-inhibitors and MEK-inhibitors.
2018
Many new drugs have appeared in last years in the oncological treatment scenario. Each drug carries an important set of adverse events, not less, cardiovascular adverse events. This aspect is even more important considering the increasing use of combination therapies with two drugs, or three drugs as in some ongoing clinical trials. Besides it represents a growing problem for Cardiologists, that face it in every day clinical practice and that will face it probably more and more in the coming years. This work reviews the mechanism of action of BRAF-inhibitors and MEK-inhibitors used together, the pathophysiological mechanisms that lead to cardiovascular toxicity. Particularly, it focuses on …

Primary and metastatic brain cancer genomics and emerging biomarkers for immunomodulatory cancer treatment
2018
Abstract: Recent studies with immunomodulatory agents targeting both cytotoxic T-lymphocyte protein 4 (CTLA4) and programmed cell death 1 (PD1)/programmed cell death ligand 1 (PDL1) have shown to be very effective in several cancers revealing an unexpected great activity in patients with both primary and metastatic brain tumors. Combining anti-CTLA4 and anti-PD1 agents as upfront systemic therapy has revealed to further increase the clinical benefit observed with single agent, even at cost of higher toxicity. Since the brain is an immunological specialized area it's crucial to establish the specific composition of the brain tumors' micro environment in order to predict the potential activit…

Immunotherapy in non-small-cell lung cancer: a bridge between research and clinical practice
2018
Lung cancer has been historically considered a poorly immunogenic disease because of the few evidence of immune responses in affected patients and the limited efficacy of immunomodulating strategies. Recent understanding of the molecular mechanisms leading to cancer immune evasion has allowed the development of a new class of drugs called immune checkpoint inhibitors, which reactivate host responses with outstanding clinical benefits in a portion of patients with non-small-cell lung cancer. In this review, we briefly summarize the basis of immunogenicity and immune escape of cancer, with specific focus on non-small-cell lung cancer, mechanisms underlying immune checkpoint inhibitors effica…

Nintedanib in NSCLC: evidence to date and place in therapy
2016
The treatment of advanced non-small cell lung cancer (NSCLC) is currently driven by the detection of targetable oncogenic drivers, i.e. epidermal growth factor receptor, echinoderm microtubule-associated protein-like 4–anaplastic lymphoma kinase, etc. Those patients who are wildtype for known and valuable oncogenes can receive standard chemotherapy as first-line treatment, with the possibility of adding bevacizumab. With regard to second-line treatment, nintedanib can improve the efficacy of docetaxel. Nintedanib is a tyrosine kinase inhibitor targeting three angiogenesis-related transmembrane receptors. The usefulness of nintedanib as an anticancer agent for NSCLC has been proved by both …
EGFR inhibition in NSCLC: New findings…. and opened questions?
2017
The targeted inhibition of epidermal growth factor receptor (EGFR) has represented a milestone in the treatment of lung cancer. Several studies convincingly and consistently demonstrated a significant superiority of EGFR-TKIs over standard platinum-chemotherapy in EGFR-mutated NSCLC patients, leading to the sequential approval of gefitinib, erlotinib and afatinib as new standard first-line clinical treatment. To date we are witnessing a second revolution in the management of EGFR-positive NSCLC thanks to the development of new treatment strategies aiming to overcome acquired resistance to TKIs and ultimately improve patients’ outcomes. In this review we summarize the most important recent f…

Detection of RAS mutations in circulating tumor DNA: a new weapon in an old war against colorectal cancer. A systematic review of literature and meta…
2019
Background: Tissue evaluation for RAS (KRAS or NRAS) gene status in metastatic colorectal cancer (mCRC) patients represent the standard of care to establish the optimal therapeutic strategy. Unfortunately, tissue biopsy is hampered by several critical limitations due to its invasiveness, difficulty to access to disease site, patient’s compliance and, more recently, neoplastic tissue spatial and temporal heterogeneity. Methods: The authors performed a systematic literature review to identify available trials with paired matched tissue and ctDNA RAS gene status evaluation. The authors searched EMBASE, MEDLINE, Cochrane, www.ClinicalTrials.gov , and abstracts from international meetings. In to…
Anti-angiogenic drugs for second-line treatment of NSCLC patients: just new pawns on the chessboard?
2016
Tumor angiogenesis is one of the main pathways targeted to treat cancer. Bevacizumab added survival benefit when combined with platinum-based chemotherapy in NSCLC. Recently, Phase III trials showed survival benefit when anti-angiogenic drugs are added to docetaxel as second-line treatment for NSCLC. These anti-angiogenic agents include nintedanib and ramucirumab, a tyrosine-kinase inhibitor and a monoclonal antibody, respectively, which target receptors involved in angiogenesis. These studies have some similarities and differences. We propose a new algorithm for treatment sequences in performance status 0-1 patients with non-oncogene-addicted NSCLC type adenocarcinoma. Indeed clearer scien…

Searching for predictive biomarkers of immunotherapy efficacy is an area of intensive investigation for translational research. Monitoring circulating tumor DNA (ctDNA) during nivolumab treatment could help clinicians to predict the immunotherapy efficacy and ultimately improve the management of patients
Prognostic clinical factors in patients affected by non-small-cell lung cancer receiving Nivolumab
2020
Background: Immune-checkpoint inhibitors have radically changed the treatment landscape of Non-Small-Cell Lung Cancer (NSCLC). It is still unclear whether specific clinical characteristics might identify those patients benefiting from immunotherapy more than others. The aim of this study was to identify clinical characteristics associated with disease-specific survival (DSS), time-to-treatment failure (TTF), objective responses (OR) and progressive disease (PD) in NSCLC patients treated with Nivolumab. Methods: This was a multicenter retrospective study conducted on 294 patients treated with Nivolumab for advanced NSCLC. Results: Of the more than 50 variables analyzed, five showed a signifi…
Cancer and the microbiome : potential applications as new tumor biomarker
2015
Abstract: Microbial communities that colonize in humans are collectively described as microbiome. According to conservative estimates, about 15% of all types of neoplasms are related to different infective agents. However, current knowledge is not sufficient to explain how the microbiome contributes to the growth and development of cancers. Large and thorough studies involving colonized, diverse and complex microbiome entities are required to identify microbiome as a potential cancer marker and to understand how the immune system is involved in response to pathogens. This article reviews the existing evidence supporting the enigmatic association of transformed microbiome with the developmen…

Stabilizing versus Destabilizing the Microtubules: A Double-Edge Sword for an Effective Cancer Treatment Option?
2015
Microtubules are dynamic and structural cellular components involved in several cell functions, including cell shape, motility, and intracellular trafficking. In proliferating cells, they are essential components in the division process through the formation of the mitotic spindle. As a result of these functions, tubulin and microtubules are targets for anticancer agents. Microtubule-targeting agents can be divided into two groups: microtubule-stabilizing, and microtubule-destabilizing agents. The former bind to the tubulin polymer and stabilize microtubules, while the latter bind to the tubulin dimers and destabilize microtubules. Alteration of tubulin-microtubule equilibrium determines th…

Entrectinib: a potent new TRK, ROS1, and ALK inhibitor
2015
Abstract: Introduction: Receptor tyrosine kinases (RTKs) and their signaling pathways, control normal cellular processes; however, their deregulation play important roles in malignant transformation. In advanced non-small cell lung cancer (NSCLC), the recognition of oncogenic activation of specific RTKs, has led to the development of molecularly targeted agents that only benefit roughly 20% of patients. Entrectinib is a pan-TRK, ROS1 and ALK inhibitor that has shown potent anti-neoplastic activity and tolerability in various neoplastic conditions, particularly NSCLC. Areas covered: This review outlines the pharmacokinetics, pharmacodynamics, mechanism of action, safety, tolerability, pre-cl…

The resistance related to targeted therapy in malignant pleural mesothelioma: Why has not the target been hit yet?
2016
Abstract: Malignant pleural mesothelioma (MPM) is an aggressive tumor of the pleura with a poor prognosis. The most active first-line regimens are platinum compounds and pemetrexed. There is no standard second-line treatment in MPM. Advances in the understanding of tumor molecular biology have led to the development of several targeted treatments, which have been evaluated in clinical trials. Unfortunately none of the explored targeted treatments can currently be recommended as routine treatment in MPM. We reviewed the biological pathways involved in MPM, the clinical trials about targeted therapy, and possible related mechanisms of resistance. We suggest that specific genetic markers are n…

In The Journal of Clinical Oncology , Ying Cheng and colleagues (1) have recently reported the results of a phase II randomized trial comparing pemetrexed plus gefitinib vs. gefitinib in treatment-naive, East Asian patients, with advanced non-squamous non-small cell lung cancer (NSCLC) and activating epidermal growth factor receptor (EGFR) mutations. The study met its primary end-point in the intent-to-treat population, showing a significantly longer median progression free survival (PFS) in favors of the combination arm (15.8 months) compared to single agent arm (10.9 months) [hazard ratio (HR): 0.68; 95% CI, 0.48 to 0.96; one-sided P=0.014; two-sided P=0.029].
Immune checkpoint inhibitors in lung cancer: the holy grail has not yet been found…
2017
Lung cancer is rich in molecular complexities and driven by different abnormal molecular pathways. Personalised medicine has begun to bring new hope for the treatment of patients with lung cancer, especially non-small cell lung cancer (NSCLC). The development of molecularly targeted therapy (small molecules and monoclonal antibodies) has significantly improved outcomes in the metastatic setting for patients with NSCLC whose tumours harbour activated oncogenes such as epidermal growth factor receptor (EGFR) and translocated genes like anaplastic lymphoma kinase (ALK). In addition, immune checkpoint inhibitors have also dramatically changed the therapeutic landscape of NSCLC. In particular, m…
Immunotherapy: is a minor god yet in the pantheon of treatments for lung cancer?
2014
Abstract: Immunotherapy has been studied for many years in lung cancer without significant results, making the majority of oncologists quite skeptical about its possible application for non-small cell lung cancer treatment. However, the recent knowledge about immune escape and subsequent cancer immunoediting has yielded the development of new strategies of cancer immunotherapy, heralding a new era of lung cancer treatment. Cancer vaccines, including both whole-cell and peptide vaccines have been tested both in early and advanced stages of non-small cell lung cancer. New immunomodulatory agents, including anti-CTLA4, anti-PD1/PDL1 monoclonal antibodies, have been investigated as monotherapy …
Abstract 448: Molecular analysis of BRAF gene and PTEN gene expression in metastatic colorectal cancer patients: Feasibility study
2014
Abstract Introduction There are numerous causes triggering CRC. 25-80% of CRC shown a deregulation in Epidermal Growth Factor Receptor (EGFR) pathway. Two signaling pathways downstream of the EGFR are dysregulated in CRC the mitogen-activated protein kinase (MAPK) and the phosphoinositide-3-kinase (PI3K) pathway. Activating mutations in KRAS and BRAF (MAPK pathway) and PIK3CA affect prognosis and/or response to anti-EGFR MoAb. PTEN is a downstream effector of EGFR pathway and is involved in PI3K pathway. Loss of PTEN protein expression can occur through epigenetic silencing and mutation or allelic loss. Immunohistochemistry (IHC) is the most effective way to assay for loss of PTEN expressio…
Multisciplinary management of patients with liver metastasis from colorectal cancer
2016
Abstract: Colorectal cancer (CRC) is one of the leading causes of cancer-related death. Surgery, radiotherapy and chemotherapy have been till now the main therapeutic strategies for disease control and improvement of the overall survival. Twenty-five per cent (25%) of CRC patients have clinically detectable liver metastases at the initial diagnosis and approximately 50% develop liver metastases during their disease course. Twenty-thirty per cent (20%-30%) are CRC patients with metastases confined to the liver. Some years ago various studies showed a curative potential for liver metastases resection. For this reason some authors proposed the conversion of unresectable liver metastases to res…
The role of cMET in non-small cell lung cancer resistant to EGFR-Inhibitors: Did we really find the target?
2014
Abstract: The advent of the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) represented the most important innovation in NSCLC treatment over the last years. However, despite a great initial activity, secondary mutations in the same target, or different alterations in other molecular pathways, inevitably occur, leading to the emergence of acquired resistance, in median within the first year of treatment. In this scenario, the mesenchymal-epidermal transition (cMET) tyrosine kinase receptor and its natural ligand, the hepatocyte growth factor (HGF), seem to play an important role. Indeed either the overexpression or the amplification of cMET, as well as the overexpr…
Extracellular vesicles as miRNA nano-shuttles : dual role in tumor progression
2018
[EN] Tumor-derived extracellular vesicles (EVs) have a pleiotropic role in cancer, interacting with target cells of the tumor microenvironment, such as fibroblasts, immune and endothelial cells. EVs can modulate tumor progression, angiogenic switch, metastasis, and immune escape. These vesicles are nano-shuttles containing a wide spectrum of miRNAs that contribute to tumor progression. MiRNAs contained in extracellular vesicles (EV-miRNAs) are disseminated in the extracellular space and are able to influence the expression of target genes with either tumor suppressor or oncogenic functions, depending on both parental and target cells. Metastatic cancer cells can balance their oncogenic pote…
Impact of phospho-Akt expression on the clinical outcome and activity of gemcitabine and Akt inhibitors in pancreatic ductal adenocarcinoma
2017
Background: Pancreatic ductal adenocarcinoma (PDAC) is among the most lethal solid tumors. Despite extensive preclinical and clinical research, the prognosis of this disease has not significantly improved, with a 5-year survival rate around 7%. There is an urgent need to better understand the molecular pathology of PDAC in order to improve patient selection for current treatment options and to develop novel therapeutic strategies. The PI3K/AKT/mTOR pathway plays a crucial role in PDAC: activation of Akt is a frequent event and has been correlated to poor prognosis and resistance to chemotherapy. Against this background, effective blockage of Akt signaling can lead to programmed cell death a…

Targeted Therapies for Non-Small Cell Lung Cancer
2015
The discovery of new oncogenic driver mutations and the clinical development of targeted therapies have completely changed the paradigm treatment of non-small cell lung cancer (NSCLC). Epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitors (TKIs), erlotinib, gefitinib, afatinib, ALK-inhibitors, crizotinib, and ceritinib, have been already approved for clinical use, benefiting many patients whose tumors harbor, respectively, EGFR or EML4-ALK molecular alterations. However, despite an initial benefit, tumor progression inevitably occurs, due to the development of acquired resistance to the targeted treatments. Several mechanisms of resistance have been identified, such as the seco…

New findings on primary and acquired resistance to anti-EGFR therapy in metastatic colorectal cancer: Do all roads lead to RAS?
2015
Abstract: Anti-epidermal growth factor receptor therapy with the monoclonal antibodies cetuximab and panitumumab is the main targeted treatment to combine with standard chemotherapy for metastatic colorectal cancer. Many clinical studies have shown the benefit of the addition of these agents for patients without mutations in the EGFR pathway. Many biomarkers, including KRAS and NRAS mutations, BRAF mutations, PIK3CA mutations, PTEN loss, AREG and EREG expression, and HER-2 amplification have already been identified to select responders to anti-EGFR agents. Among these alterations KRAS and NRAS mutations are currently recognized as the best predictive factors for primary resistance. Liquid b…
Novel therapeutic strategies for patients with NSCLC that do not respond to treatment with EGFR inhibitors
2014
Abstract: Introduction: Treatment with epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) yields tumour responses in non-small cell lung cancer (NSCLC) patients harbouring activating EGFR mutations. However, even in long-lasting responses, resistance to EGFR TKIs invariably occurs. Areas covered: This review examines resistance mechanisms to EGFR TKI treatment, which mainly arise from secondary EGFR mutations. Other resistance-inducing processes include mesenchymal-epithelial transition factor (MET) amplification, epithelial-mesenchymal transformation, phenotypic change from NSCLC to small-cell lung carcinoma, and modifications in parallel signalling pathways. Current…
Next-Generation Sequencing in Clinical Practice
2019
Abstract During the past few decades, Sanger sequencing represented the “gold standard” technique. In order to better define the mutational status of several genes at the same time, next-generation sequencing methodologies have been introduced in the molecular laboratory workflow. In the era of personalized medicine, this technological improvement plays a key role in the comprehensive molecular characterization of cancer patients in order to get a “tile” target therapy. For different cancer patients, different target therapies are available and different genes serve as clinical it relevant biomarkers. This chapter reviews the principal features of these novel technologies and their applicat…
The effects of enzalutamide and abiraterone on skeletal related events and bone radiological progression free survival in castration resistant prosta…
2017
Two new drugs, the CYP17 inhibitor abiraterone acetate and the androgen receptor (AR) antagonist enzalutamide, have recently shown to prolong OS prior chemotherapy or in docetaxel treated mCRPC patients, using steroidal therapy or placebo as control group. Updated analyses underlined the role of these new agents on two prostate-specific endpoints as radiographic progression-free survival (rPFS) and time to first skeletal-related event (tSRE). On the basis of these reports, we made an indirect comparison between abiraterone and enzalutamide. We obtained a clinically but not significant difference favouring enzalutamide over abiraterone in terms of rPFS (HR 0.48, 95% CI 0.22â1.02). No signi…
Immuno-targeted combinations in oncogene-addicted non-small cell lung cancer
2018
The identification of tumor “oncogenic drivers” and the subsequent development of targeted therapy represented a milestone in the treatment of lung cancer over the last years. Tumor genotyping has been incorporated into therapeutic decision making of advanced non-small cell lung cancer (NSCLC) since has become clear that individuals with actionable molecular alterations receiving a matched targeted agent certainly live longer and better. The recent understanding of biological mechanisms underlying cancer immune evasion has allowed the development of a new class of immunomodulatory agents which are able to reactivate host immune-response, offering the potential for long-term disease control …
Liquid Biopsy in Non-Small Cell Lung Cancer (NSCLC)
2017
Lung cancer is the leading cause of cancer deaths worldwide. To date, the gold standard for the molecular analysis of a patient affected by NSCLC is the tissue biopsy. The discovery of activating mutations and rearrangements in specific genes has revolutionized the therapeutic approaches of lung cancer over the last years. For this reason, a strict “molecular follow-up” is mandatory to evaluate patient’s disease evolution. Indeed, liquid biopsy has raised as the “new ambrosia of researchers” as it could help clinicians to identify both prognostic and predictive biomarkers in a more accessible way. Liquid biopsy analysis can be used in different moments starting from diagnosis to relapse, ea…

Potential Role of ANGPTL4 in the Cross Talk between Metabolism and Cancer through PPAR Signaling Pathway
2017
The angiopoietin-like 4 (ANGPTL4) protein belongs to a superfamily of secreted proteins structurally related to factors modulating angiogenesis known as angiopoietins. At first, ANGPTL4 has been identified as an adipokine exclusively involved in lipid metabolism, because of its prevalent expression in liver and adipose tissue. This protein regulates lipid metabolism by inhibiting lipoprotein lipase (LPL) activity and stimulating lipolysis of white adipose tissue (WAT), resulting in increased levels of plasma triglycerides (TG) and fatty acids. Subsequently, ANGPTL4 has been shown to be involved in several nonmetabolic and metabolic conditions, both physiological and pathological, including …
ALK and crizotinib: After the honeymoon...what else? Resistance mechanisms and new therapies to overcome it
2014
The last few decades have witnessed a silent revolution in the war against NSCLC, thanks to the discovery of “oncogenic drivers” and the subsequent development of targeted therapies. The discovery of the EML4-ALK fusion gene in a subgroup of patients with NSCLC and the subsequent clinical development of crizotinib has been an amazing success story in lung cancer translational-research, and its accelerated approval [only 4 years from the discovery of ALK rearrangement in NSCLC to the approval by the Food and Drug Administration (FDA)] marked the beginning of the new decade of targeted therapy. However, common to all targeted therapies, despite an initial benefit, patients inevitably experien…
The role of microRNAs in driving EGFR-TKI resistance in NSCLC cell lines
2016
Background: the inhibition of EGFR kinase activity by tyrosine kinase inhibitors (EGFR-TKIs), such as gefitinib and erlotinib, can result in improved response and prolonged progression-free survival (PFS) in NSCLC patients harboring sensitizing exon 19del and exon 21 L858R mutations. Unfortunately, almost all patients will develop resistance to EGFR-TKI, in particular T790M is the most frequent mutation. Nowadays, new methods are urgently needed for a rapid, cost-effective and non-invasive identification of biomarkers as a valuable tool for obtaining the genetic follow-up data during the course of the disease. Circulating microRNAs might represent a new precious biomarker for patients’ moni…

This meta-analysis aims to review all the studies reporting survival outcomes (recurrence free survival (RFS), and/or overall survival (OS)) of patients undergoing resection of CLM, stratified according to KRAS and/or BRAF mutation status. Materials and Methods: Data from all published studies reporting survival outcomes (RFS and/or OS) of CRC patients who received resection of CLM, stratified by KRAS and/or BRAF mutation status were collected by sear…
Immune-Biomarkers in Advanced Non-Small Cell Lung Cancer
2021
N.A Background: Developing personalized immunotherapy-based approaches, through the identification of predictive immune-related biomarkers, is still a main topic for translational lung cancer research. In the present study we investigated whether baseline tissue “immune-related gene signatures”, as well as plasma chemo-cytokines profiles, could predict sensitivity/resistance to immune-checkpoint inhibitors in pre-treated patients with advanced non-small cell lung cancer (NSCLC). Methods: From September 2015 to September 2018, 150 patients with previously treated advanced NSCLC who received either anti-PD1 or anti-PD-L1 inhibitors in the second-third line setting were included within this tr…
