Clinical observation of crizotinib in the treatment of ALK-positive advanced non-small cell lung cancer

ConclusionsThe efficacy of crizotinib in patients with advanced NSCLC is related to the number of metastatic organs, age and timing of treatment. The use of crizotinib is prone to intracranial progression, and progression of simple brain metastases is not an indication that crizotinib is discontinued. Patients will continue to benefit from combination of local radiotherapy.

To achieve this goal, extensive studies have demonstrated the radiosensitization potential of the gold nanoparticles (AuNPs) during treatment with low-energy ionizing radiation due to their high-photoelectric absorption coefficient. Compared to the AuNPs, t...

Authors: Stasi C, Sadalla S, Carradori E, Monti M, Petraccia L, Madia F, Gragnani L, Zignego AL Abstract BACKGROUND. New direct-acting antiviral drugs can eradicate hepatitis C virus (HCV) infection in over 90% of patients and can even reduce the risk of complications in advanced fibrosis/cirrhosis. The aims of this study were to evaluate 1) changes in fibrosis during and after antiviral treatment and 2) incidence of hepatocarcinoma and mortality in various fibrosis stages.METHODS. This is a longitudinal monocentric prospective study. Blood and instrumental examinations were evaluated at baseline, at the end of the...

The present study was organized to evaluate this pomegranate's potential in the biosynthesis of silver nanoparticles as well as bio-medical activities. According to the results, the pomegranate peel extract incredibly inhibited 100% of DPPH free radicals (EC50 = 5 μg/mL). This extract also induced more than ...

Our study intended to investigate whether curcumin potentiates GBA-induced anti-tumor effect in non-small cell lung cancer cells.Materials and methodsThe combined effect of GBA and curcumin on cell viability was examined by MTT analysis. Cellular apoptosis was evaluated by flow cytometry analysis. Aut...

In this study, the correlation between ZBTB7A and ER-α was confirmed by tissue microarray-based and TCGA database. Then, we explore if ZBTB7A maintains ER-α’s level via targeting ER-α’s expression or degradation. Finally, we examined the effect of ZBTB7A on the proliferation of breast cancer cells.Key findingsWe further confirmed that ZBTB7A shows a significant positive correlation with ER-α in clinical breast cancer samples by tissue microarray-based analysis. Mechanically, we identified that the inhibition of ZBTB7A could upregulate E3 ligase TRIM25 leading to enhancement of ER-α...

We investigated the molecular alterations associated with anticancer effects of usnic acid against human gastric adenocarcinoma AGS and gastric carcinoma SNU-1 cells. Usnic acid (10–25 μM) treatment to these cells caused a significant increase in mitochondrial membrane depolarization and apoptotic cells. Apoptosis induction was...

In this study, we aimed to explore the efficacy and safety profile of apatinib monotherapy, or combined with chemotherapy or endothelial growth factor receptor (EGFR)-TKI in heavily pretreated non-small cell lung cancer (NSCLC) patients with brain metastases. We performed a retrospective analysis for relapsed NSCLC patients with brain metastases from our institute, whom received apatinib (250mg or 500mg p.o. qd) monotherapy, or combination with EGFR-TKI or chemotherapy as second- or more line systemic therapy until disease progression or unacceptable toxicity occurred. The objective response rate (ORR), disease control rat...

In conclusion, we showed hypermethylation of CpGs as a novel mechanism of action for DNMTi agents and identified 638 hypermethylated molecular targets (CpGs) common to decitabine and azacytidine therapy. These novel results suggest that hypermethylation of CpGs should be considered when predicting the DNMTi responses and side effects in cancer patients. Introduction DNA methyltransferase inhibitors (DNMTi) are widely used as chemical tools for hypomethylating the genome, with an aim to understand the role of DNA methylation in multiple processes (e.g., X-chromosome inactivation and DNA imprinting) and as an anti-ca...
