Amphiregulin contained in NSCLC-exosomes induces osteoclast differentiation through the activation of EGFR pathway
2017
AbstractNon-small cell lung cancer (NSCLC) remains the leading cause of cancer-related deaths worldwide. The majority of patients are diagnosed in advanced disease stage. Bone metastasis is the most frequent complication in NSCLC resulting in osteolytic lesions. The perfect balance between bone-resorbing osteoclasts and bone-forming osteoblasts activity is lost in bone metastasis, inducing osteoclastogenesis. In NSCLC, the epidermal growth factor receptor (EGFR) pathway is constitutively activated. EGFR binds Amphiregulin (AREG) that is overexpressed in several cancers such as colon, breast and lung. Its levels in plasma of NSCLC patients correlate with poor prognosis and AREG was recently …
Central nervous system involvement in ALK-rearranged NSCLC : promising strategies to overcome crizotinib resistance
2016
ABSTRACT: Introduction: ALK rearranged Non Small Cell Lung Cancers (NSCLCs) represent a distinct subgroup of patients with peculiar clinic-pathological features. These patients exhibit dramatic responses when treated with the ALK tyrosine kinase inhibitor Crizotinib, albeit Central Nervous System (CNS) activity is much less impressive than that observed against extracranial lesions. CNS involvement has become increasingly observed in these patients, given their prolonged survival. Several novel generation ALK inhibitors have been developing to increase CNS penetration and to provide more complete ALK inhibition. Areas covered: The CNS activity of Crizotinib and novel generation ALK inhibito…
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…
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…
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…
Clinical utility of plasma-based digital next-generation sequencing in oncogene-driven non-small-cell lung cancer patients with tyrosine kinase inhib…
2019
[Objectives] Resistance to tyrosine-kinase inhibitors (TKIs) is a clinical challenge in patients with oncogene-driven non-small-cell lung cancers (NSCLC). We have analyzed the utility of next-generation sequencing (NGS) of cell-free circulating tumor DNA (ctDNA) to impact the clinical care of patients with TKI resistance.
The diagnostic accuracy of circulating tumor DNA for the detection of EGFR-T790M mutation in NSCLC: a systematic review and meta-analysis
2018
AbstractThis pooled analysis aims at evaluating the diagnostic accuracy of circulating tumor (ct) DNA for the detection of EGFR-T790M mutation in NSCLC patients who progressed after EGFR-TKIs. Data from all published studies, reporting both sensitivity and specificity of plasma-based EGFR-T790M mutation testing by ctDNA were collected by searching in PubMed, Cochrane Library, American Society of Clinical Oncology, European Society of Medical Oncology and World Conference of Lung Cancer meeting proceedings. A total of twenty-one studies, with 1639 patients, were eligible. The pooled sensitivity of ctDNA analysis was 0.67 (95% CI: 0.64–0.70) and the pooled specificity was 0.80 (95% CI: 0.77–0…

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 …
NEPA as antiemetic prophylaxis after failure of 5HT3-RA plus dexamethasone in patients receiving carboplatin and gemcitabine chemotherapy: A monocent…
2020
Introduction Chemotherapy-induced nausea and vomiting (CINV) may affect adherence to planned chemotherapy treatments and compromise patients’ quality of life during the therapy. NEPA is an oral fixed combination of netupitant, a highly-selective NK1-RA and palonosetron, a 5HT3-RA, approved for the prevention of acute and delayed CINV. The aim of this study was to evaluate the efficacy and safety of NEPA with dexamethasone for CINV prophylaxis in the challenging setting of carboplatin and gemcitabine combination chemotherapy, after failure of prophylaxis with 5HT3 receptor antagonist. Methods Eligible patients were undergoing carboplatin and gemcitabine combination chemotherapy for metastati…
