Immunonutritive Scoring in Patients With Hepatocellular Carcinoma Undergoing Transarterial Chemoembolization: Prognostic Nutritional Index or Control…
2021
ObjectivesThe Prognostic Nutritional Index (PNI) and Controlling Nutritional Status (CONUT) score are immunonutritive scoring systems with proven predictive ability in various cancer entities, including hepatocellular carcinoma (HCC). We performed the first evaluation of the CONUT score for patients undergoing transarterial chemoembolization (TACE) and compared CONUT and PNI in the ability to predict median overall survival (OS).MethodsBetween 2010 and 2020, we retrospectively identified 237 treatment-naïve patients with HCC who underwent initial TACE at our institution. Both scores include the albumin level and total lymphocyte count. The CONUT additionally includes the cholesterol level. …
A phase Ib/II study of HER3-targeting lumretuzumab in combination with carboplatin and paclitaxel as first-line treatment in patients with advanced o…
2019
Purpose This study investigated the safety and clinical activity of lumretuzumab, a humanised antihuman epidermal growth factor receptor 3 (HER3) monoclonal antibody, in combination with carboplatin and paclitaxel in first-line treatment of patients with squamous non-small cell lung cancer (sqNSCLC). HER3 ligand heregulin and HER3 protein expression were evaluated as potential biomarkers of clinical activity. Patients and methods This open-label, phase Ib/II study enrolled patients receiving lumretuzumab at 800 mg (flat) in combination with carboplatin (area under the curve (AUC) 6 mg/mL×min) and paclitaxel (200 mg/m 2) administered intravenously on a every 3-week schedule. Adverse event (A…
A Conceptual Review on Using Consequential Life Cycle Assessment Methodology for the Energy Sector
2020
Energy is engaged in the supply chain of many economic sectors; therefore, the environmental impacts of the energy sector are indirectly linked to those of other sectors. Consequential life cycle assessment (CLCA) is an appropriate methodology to examine the direct and indirect environmental impacts of a product due to technological, economic or social changes. To date, different methodological approaches are proposed, combining economic and environmental models. This paper reviews the basic concept of CLCA and the coupling of economic and environmental models for performing CLCA in the energy sector during the period 2006–2020, with the aim to provide a description of the different tools, …
Design, synthesis and biological evaluation of new anticancer drugs: FGFR inhibitors
2021
Fibroblast growth factor receptors (FGFRs) constitute a family of tyrosine kinases receptors (RTKs) that exert pivotal physiological functions in human embryonic and adult tissues. Hyperactivated FGFR signaling drives tumorigenesis in multiple cancer types, including lung and brain cancers. Great effort has been laid on the development of new compounds that specifically target the FGFR axis. However, cancer cell- based and microenvironmental resistance mechanisms against FGFR inhibitors often arise and are currently poorly understood. Furthermore, FGFR-targeted therapy often presents different side effects, e due to the broad biological spectrum of the FGFR signaling axis as well as to its …
Gefitinib in lung cancer therapy. Clinical results, predictive markers of response and future perspectives.
2009
Over the past few years, epidermal growth factor receptor has emerged as one of the most important targets in tumorgenesis and several drugs targeting signal transduction pathways have been developed. The first among these agents to be approved for the treatment of NSCLC was gefitinib, a potent, selective and reversible inhibitor of HER1/EGFR tyrosine kinase activity. The review summarizes its clinical development and the new therapeutic options, with particular focus on predictive markers of susceptibility to this drug.
Non-small cell lung cancer (NSCLC), EGFR downstream pathway activation and TKI targeted therapies sensitivity: Effect of the plasma membrane-associat…
2017
Adenocarcinoma of Non-Small Cell Lung Cancer (NSCLC) is a severe disease. Patients carrying EGFR mutations may benefit from EGFR targeted therapies (e.g.: gefitinib). Recently, it has been shown that sialidase NEU3 directly interacts and regulates EGFR. In this work, we investigate the effect of sialidase NEU3 overexpression on EGFR pathways activation and EGFR targeted therapies sensitivity, in a series of lung cancer cell lines. NEU3 overexpression, forced after transfection, does not affect NSCLC cell viability. We demonstrate that NEU3 overexpression stimulates the ERK pathway but this activation is completely abolished by gefitinib treatment. The Akt pathway is also hyper-activated upo…
Les traitements péri-opératoires des cancers bronchiques non à petites cellules (CNPC) : standards actuels et perspectives
2019
Resume La chirurgie est le traitement de reference des CNPC de stades I, II et IIIA. Plusieurs essais randomises de phase III de chimiotherapie adjuvante ou neoadjuvante avec une chimiotherapie a base de platine ont ete menes dans les cancers de stades I, II et IIIA. Ces essais ont demontre un gain de survie significatif de la chimiotherapie adjuvante ou neoadjuvante evalue a 5 % a 5 ans dans les stades II et IIIA. Ce benefice a ete confirme par deux meta-analyses sur donnees individuelles. En revanche pour les stades I, le benefice de la chimiotherapie n’est que suggere dans les stades IB > 4 cm. La place de la radiotherapie adjuvante dans les tumeurs N2, sera precisee par l’essai Lung-ART…
Assessing the impact of COVID-19 on liver cancer management (CERO-19)
2021
[Background & Aims] The coronavirus disease 2019 (COVID-19) pandemic has posed unprecedented challenges to healthcare systems and it may have heavily impacted patients with liver cancer (LC). Herein, we evaluated whether the schedule of LC screening or procedures has been interrupted or delayed because of the COVID-19 pandemic.
EGFR tyrosine kinase inhibitor therapy continuation with high-dose hypofractionated radiotherapy in EGFR-mutated non-small cell lung cancer (NSCLC) p…
2020
e21580 Background: EGFR tyrosine kinase inhibitors (TKIs) represent the standard first-line therapy for advanced non-small cell lung cancer (NSCLC) patients with activating EGFR mutations. However, despite initial marked responses, tumors invariably develop acquired resistance to TKIs. Oligoprogression is commonly observed during treatment with oncogene-directed therapies, including EGFR TKIs, and refers to patients who experience disease progression only in limited sites as a result of heterogeneous mechanisms of resistance. The use of local ablative treatments for these resistant lesions may extend the duration of TKI therapy and potentially improve long-term disease control and survival…
Updated insights into the mechanism of action and clinical profile of the immunoadjuvant QS-21: A review
2019
Background Vaccine adjuvants are compounds that significantly enhance/prolong the immune response to a co-administered antigen. The limitations of the use of aluminium salts that are unable to elicite cell responses against intracellular pathogens such as those causing malaria, tuberculosis, or AIDS, have driven the development of new alternative adjuvants such as QS-21, a triterpene saponin purified from Quillaja saponaria. Purpose The aim of this review is to attempt to clarify the mechanism of action of QS-21 through either receptors or signaling pathways in vitro and in vivo with special emphasis on the co-administration with other immunostimulants in new adjuvant formulations, called a…
