Cell apoptosis, viability, and enzyme-linked immunosorbent assay test were used to study the immune suppression by EGFR activation and immune reactivation by EGFR-TKIs and/or PD-1 blocking in tumor cells and human peripheral blood mononuclear cells coculture system. We found that EGFR activation ...
Significance of differences was determined by Student’s t test (∗p < 0.05, ∗∗p < 0.01). d Proposed mechanism for the efficacy of the combination strategy in ASK120067-resistant NCI-H1975 cells Full size image On the basis of our findings, the potential mechanism whereby Ack1/AKT ...
The impact of the different variables on long-term outcomes was analysed using the Kaplan–Meier method of analysing disease- specific survival (DSS); the survival data were compared using the log-rank test. RESULTS In all, 57 patients were male (74%) and 20 were female (26%); their ...
liquid biopsy has the potential to become a complementary/alternative tool for diagnosis and prognosis to conventional tissue biopsy. This method comprises the detection of proteomic and genomic information from body fluids, specifically samples of blood. Moreover, this approach has promise for clinical...
The diffuse infiltrative growth of tumor cells within the central nervous system (CNS) still represents a major problem for effective therapeutic intervention as the delivery of active therapeutic agents to the invasive tumor cells is limited by the blood–brain barrier (BBB). While factors that ...
Grade 3 or higher TEAEs occurred in 99 patients (61.5%) in the ivonescimab group vs 79 patients (49.1%) in the placebo group. The most common grade 3 or higher TEAEs were neutrophil count decreased (31.1% vs 19.3%), white blood cell count decreased (20.5% vs 16.8%), platelet coun...
Time-to-event end point was analysed using the Kaplan–Meier method, and DFS and OS of subgroups were compared using the log-rank test. Univariate and multivariate analyses were performed to identify independent prognostic factors for survival using the Cox proportional hazard regression model. ...
