A Three-agent Regimen for Triple Negative Breast Cancer Treatment.

Background: Triple-negative breast cancer (TNBC) has a poor prognosis with current treatment options. Novel therapeutic strategies are urgently needed to enhance treatment outcomes for TNBC.

Objective: This study evaluated the efficacy of a three-agent regimen compared to existing treatment regimens in a TNBC mouse model, and elucidated its potential mechanisms of action.

First-in-human phase I/Ib study of QL1706 (PSB205), a bifunctional PD1/CTLA4 dual blocker, in patients with advanced solid tumors.

Background: QL1706 (PSB205) is a single bifunctional MabPair (a novel technical platform) product consisting of two engineered monoclonal antibodies (anti-PD-1 IgG4 and anti-CTLA-4 IgG1), with a shorter elimination half-life (t) for CTLA-4. We report results from a phase I/Ib study of QL1706 in patients with advanced solid tumors who failed standard therapies.

Methods: In the phase I study, QL1706 was administered intravenously once every 3 weeks at one of five doses ranging from 0.

Treatment Patterns and Outcomes in Chinese Patients with Gastric Cancer by HER2 Status: A Noninterventional Registry Study (EVIDENCE).

Background: Real-world safety and effectiveness data for trastuzumab plus chemotherapy treatment of patients with HER2-positive metastatic gastric cancer (mGC) in China are lacking.

Patients And Methods: EVIDENCE was a prospective, multicenter, noninterventional registry study evaluating the safety and effectiveness of trastuzumab in five cohorts of Chinese patients with gastric cancer, stratified by HER2 status and trastuzumab treatment. Effectiveness was analyzed for cohorts I (HER2-positive, trastuzumab treated), II (HER2-positive, trastuzumab untreated), and IV (HER2-negative, trastuzumab untreated); trastuzumab-related adverse events (AEs) were analyzed for cohort I.

Routine-Dose and High-Dose Icotinib in Patients with Advanced Non-Small Cell Lung Cancer Harboring EGFR Exon 21-L858R Mutation: the Randomized, Phase II, INCREASE Trial.

Purpose: Our primary purpose is to explore safety and efficacy of high-dose icotinib in comparison with routine-dose icotinib in patients with non-small cell lung cancer (NSCLC) harboring 21-L858R mutation.

Patients And Methods: Patients with treatment-naïve, EGFR-mutant (21-L858R or exon 19 deletion at 2:1) NSCLC were enrolled. Patients with 21-L858R mutation were randomized to receive routine-dose icotinib (125 mg, thrice daily; L858R-RD) or high-dose icotinib (250 mg, thrice daily; L858R-HD), whereas patients with exon 19 deletion received only routine-dose icotinib (19-Del-RD) until progression, death, or unacceptable toxicity.

WBSCR22 Competes with Long Non-coding RNA Linc00346 for miR-509-5p Binding Site to Regulate Cancer Stem Cell Phenotypes of Colorectal Cancer.

Various Long non-coding RNAs (lncRNAs) and MicroRNAs (miRNAs) have been demonstrated to be involved in colorectal cancer stem cells (CSCs). WBSCR22 is a key gene we previously found that functions in colorectal cancer (CRC). This paper aims to investigate the effects of WBSCR22 and its corresponding miRNA and lncRNA in CRC.

Differentiation antagonizing non-protein coding RNA modulates the proliferation, migration, and angiogenesis of glioma cells by targeting the miR-216a/LGR5 axis and the PI3K/AKT signaling pathway.

DANCR plays an important role in various types of cancer. However, its role in gliomas remains unclear. In the present study, we aimed to investigate the mechanism underlying the role of DANCR in gliomas.

miR-655-3p inhibits cell migration and invasion by targeting pituitary tumor-transforming 1 in non-small cell lung cancer.

miR-655-3p functions as a tumor suppressor in tumor metastases; however, its role and mechanism in regulating cell migration and invasion of non-small cell lung cancer (NSCLC) remain unclear. Here, we found that miR-655-3p expression was markedly decreased in the NSCLC cell lines A549, NCI-H1650, PC14/b, NCI-H1299, and HPAEpiC compared to levels observed in normal human lung fibroblasts. miR-655-3p overexpression significantly inhibited migration and invasion of A549 and PC14/b cells, and pituitary tumor-transforming 1 (PTTG1) expression was up-regulated in the NSCLC cells.

Efficacy and safety of direct oral anticoagulants versus low-molecular-weight heparin in patients with cancer: a systematic review and meta-analysis.

The efficacy and safety of direct oral anticoagulants (DOACs) versus low-molecular-weight heparin (LMWH) are still debated in the treatment of patients with cancer, and the optimal duration of therapy remains uncertain. Electronic databases (PubMed, Embase, and Cochrane Library) were searched to retrieve studies on the efficacy and safety of DOACs versus LMWH in treating patients with cancer from January 1980 to October 2018. The primary efficacy and safety endpoints were recurrent venous thromboembolism (VTE) and major bleeding.

Natural killer cells inhibit oxaliplatin-resistant colorectal cancer by repressing WBSCR22 via upregulating microRNA-146b-5p.

Natural killer (NK) cells have exhibited promising efficacy in inhibiting cancer growth. We aimed to explorer the effect of NK cells on oxaliplatin-resistant colorectal cancer and the underlying molecular mechanism. Oxaliplatin-resistant colorectal cancer cell lines were co-cultured with NK cells to evaluate the effect on viability, proliferation, migration and invasion .

Combination of cytokine-induced killer and dendritic cells pulsed with antigenic α-1,3-galactosyl epitope-enhanced lymphoma cell membrane for effective B-cell lymphoma immunotherapy.

Background Aims: Refractory B-cell lymphomas are difficult to successfully treat with current chemotherapeutic regimens; however, immunotherapy may be an effective form of treatment for these patients.

Methods: Fourteen refractory lymphoma patients (age, 29-74 y) were enrolled in the trial. α-1,3-galactosyl (α-Gal) epitopes were synthesized on lymphoma cell membranes with the use of bovine recombinant α-1,3-galactosyltransferase (α-GT) and neuraminidase to enhance tumor immunogenicity.
