Resistance to epidermal growth factor receptor inhibition in non-small cell lung cancer
2018
EGFR mutant cfDNA and CTC detection as biomarkers in patients diagnosed with advanced non-small cell lung cancer.
2016
e23039Background: One of the most promising developments in translational cancer has been the emergence of liquid biopsy as a non-invasive biomarker. CTCs and cfDNA offer valuable prognostic and pr...
Differential expression of tumorspheres in CSC-markers and signaling pathways from non-small cell lung cancer.
2016
e23276Background: Chemoresistance, tumor progression and metastasis have made of lung cancer the first cause of death cancer-related worldwide. Cancer stem cells (CSCs) are small subpopulations of ...
ctDNA levels before treatment predict survival in non-small cell lung cancer patients treated with a tyrosine kinase inhibitor.
2020
9542 Background: Currently there is an intense debate concerning therapeutic strategies in EGFR positive NSCLC patients with advance disease. Osimertinib is superior to standard EGFR Tyrosine Kinase Inhibitors (TKIs) as first line treatment. However, it is yet unclear whether this option is superior to sequential treatment of a 1st or 2nd generation TKI followed by osimertinib. In order to clarify this issue it is important to identify which patients are at high risk of progression disease. Methods: This is a prospective, multicentre, cross-sectional study promoted by Spanish Lung Cancer Group. 698 plasma samples from 196 advanced NSCLC patients with tumors harboring an EGFR activating mut…
A phase III study (APROMISS) of AL3818 (Catequentinib, Anlotinib) hydrochloride monotherapy in subjects with metastatic or advanced synovial sarcoma.
2021
11505 Background: AL3818 (Catequentinib, Anlotinib) is a novel, orally administered, small molecule tyrosine kinase inhibitor. The primary objective of this Phase 3 study is to evaluate the efficacy of AL3818 monotherapy in patients (pts) with synovial sarcoma (SS) comparing with dacarbazine in randomization setting. Methods: Patients with a diagnosis of synovial sarcoma requiring second line or further line treatment were eligible for enrollment. The regimen was a 21-day cycle with oral AL3818 administered on 14 days on and 7 days off. This phase 3 trial is randomized in 2:1 ratio of AL3818 comparing to dacarbazine with option of crossover after PD of dacarbazine treatment. Progression fr…
Gene Amplification-Associated Overexpression of the Selenoprotein tRNA Enzyme TRIT1 Confers Sensitivity to Arsenic Trioxide in Small-Cell Lung Cancer
2021
Simple Summary Small-cell lung cancer accounts for approximately 13% of all new lung cancer diagnoses, but in contrast to non-small-cell lung cancer, the implementation of targeted treatments in small-cell lung cancer has been limited, with little improvement in the clinical outcome in the last several decades. Exploring new pathways for targeted therapy, we have observed that extra-copies of the tRNA modifier TRIT1, involved in the translation of selenoproteins, confers sensitivity to arsenic trioxide in small-cell lung cancer. This finding could open a new therapeutic niche for a tumor type with such a dismal clinical course. The alteration of RNA modification patterns is emerging as a co…
The role of second-line tyrosine kinase inhibitor monotherapy in EGFR wild-type advanced non-small-cell lung cancer patients: Findings from a retrosp…
2015
e19030 Background: Second-line treatment for advanced non-small-cell lung cancer (aNSCLC) patients includes monotherapy with a third generation cytotoxic drug (CT) or with the tyrosine kinase inhib...
Soluble biomarker signature to predict outcome of patients with non-small-cell lung cancer (NSCLC) treated with anti-PD1/PDL1 monoclonal antibodies.
2019
e20685 Background: Immunotherapy with anti-PD1/PDL1 monoclonal antibodies has become the second line standard treatment for most patients diagnosed of advanced Non-Small-Cell lung cancer (NSCLC). The aim of this study is to assess the utility of circulating biomarkers such as sPDL1, sPDL2, sCD137, sIDO, sTIM3, sCD28, sCD27, sCTLA4, sHVEM, sLAG3, sCD80 and sGITR for predicting efficacy of immunotherapy with anti-PD1/PDL1 therapies. Methods: Blood samples were collected before treatment from 50 NSCLC patients who received anti PD1/PDL1 therapies (second line). Plasma biomarkers´ levels were measured by Multiplex bead-based assays. Continuous variables were categorized using the median as a c…
Improved inter-observer agreement of an expert review panel in an oncology treatment trial--Insights from a structured interventional process.
2015
Abstract Purpose Oncologic imaging is a key for successful cancer treatment. While the quality assurance (QA) of image acquisition protocols has already been focussed, QA of reading and reporting offers still room for improvement. The latter was addressed in the context of a prospective multicentre trial on fluoro-deoxyglucose (FDG)–positron-emission tomography (PET)/CT-based chemoradiotherapy for locally advanced non-small cell lung cancer (NSCLC). Material and methods An expert panel was prospectively installed performing blinded reviews of mediastinal NSCLC involvement in FDG–PET/CT. Due to a high initial reporting inter-observer disagreement, the independent data monitoring committee (I…
Phase II study of mitomycin C, etoposide and vindesine in metastatic stage IV non-small-cell lung cancer.
1991
A total of 72 patients with metastatic stage IV non-small-cell lung cancer (NSCLC) were treated with combination chemotherapy comprising the MEV regimen (mitomycin C, 8 mg/m2 given i. v. on day 1; etoposide, 100 mg/m2 given i.v. on days 1–3; and vindesine, 3 mg/m2 given i.v. on day 1; treatment repeated every 3 weeks). In 64 evaluable patients, the objective response rate was 37% (complete responses, 4.7%; partial responses, 32.3%). The median survival was 7.6 months for all patients. The treatment was very well tolerated. MEV proved to be an active and non-toxic regimen for the treatment of metastatic NSCLC.
