Apatinib plus vinorelbine versus vinorelbine for metastatic triple-negative breast cancer who failed first/second-line treatment: the NAN trial.

While therapies such as chemotherapy combined with immunotherapy, sacituzumab govitecan, and PARP inhibitors are available for metastatic TNBC, on disease progression after these therapies, the mainstay of therapy is chemotherapy. Apatinib is a small-molecule tyrosine kinase inhibitor that has promising anti-angiogenesis and antitumor activity for TNBC. We aimed to evaluate the safety and efficacy of adding apatinib to chemotherapy in patients with advanced TNBC with failed first/second-line treatment.

Maintenance chemotherapy is effective in patients with metastatic triple negative breast cancer after first-line platinum-based chemotherapy.

Background: Platinum-based chemotherapy (PBCT) has gained an important position as a first-line treatment for metastatic triple-negative breast cancer (mTNBC). We assessed whether maintenance chemotherapy maintenance was superior to observation after first-line PBCT in patients with mTNBC.

Methods: A total of 265 patients with mTNBC who had exhibited non-PD after 4-6 cycles of firstline PBCT at the Fudan University Shanghai Cancer Center from January 2008 to April 2019 were retrospectively analyzed.

The human chemokine receptor CCRL2 suppresses chemotaxis and invasion by blocking CCL2-induced phosphorylation of p38 MAPK in human breast cancer cells.

The human chemokine receptor CCRL2 is a member of the atypical chemokine receptor family. CCRL2 is unable to couple with G-proteins and fails to induce classical chemokine signaling for the highly conserved DRYLAIV motif essential for signaling has been changed to QRYLVFL. We investigated whether CCRL2 is involved in the chemotaxis, invasion, and proliferation of human breast cancer cells.

Intermittent high dose proton pump inhibitor enhances the antitumor effects of chemotherapy in metastatic breast cancer.

Background: Acidity is a hallmark of malignant tumor, representing a very efficient mechanism of chemoresistance. Proton pump inhibitors (PPI) at high dosage have been shown to sensitize chemoresistant human tumor cells and tumors to cytotoxic molecules. The aim of this pilot study was to investigate the efficacy of PPI in improving the clinical outcome of docetaxel + cisplatin regimen in patients with metastatic breast cancer (MBC).

Vinorelbine and capecitabine in anthracycline- and/or taxane-pretreated metastatic breast cancer: sequential or combinational?

Purpose: The difference between combinational and pre-planned sequential therapies using regimens that include non-anthracycline and taxane in the first-line setting remains unclear. The purpose of this study is to explore the interaction between vinorelbine (N) and capecitabine (X) in breast cancer cells and to compare the simultaneous or sequential administration of the two drugs in patients with metastatic breast cancer (MBC) as first-line treatment.

Methods: First, we explored the effects of vinorelbine on thymidine phosphorylase (TP) and thymidylate synthase (TS) expression in breast cancer cells.

Phase II study of oxaliplatin plus leucovorin and 5-fluorouracil in heavily pretreated metastatic breast cancer patients.

The aim of this phase II study was to investigate the efficacy and safety of oxaliplatin plus 5-fluorouracil (5-FU) and leucovorin (LV) in metastatic breast cancer (MBC) patients heavily pretreated with anthracyclines, taxanes, vinorelbine, gemcitabine, and capecitabine. Sixty-two women who had received at least 3 above-mentioned drug classes were treated with oxaliplatin 85 mg/m(2) as a 2-h infusion on day 1, LV 200 mg/m(2) as a 2-h infusion followed by bolus 5-FU 400 mg/m(2) on day 1, and a continuous infusion of 5-FU 1,200 mg/m(2) for 44 h. The median patient age was 52 years with a median of two involved organs, and the metastases were mostly in the lung (53.

Lack of association between methylenetetrahydrofolate reductase gene A1298C polymorphism and breast cancer susceptibility.

Published data on the association between methylenetetrahydrofolate reductase gene (MTHFR) A1298C polymorphism and breast cancer risk are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. Medline, PubMed, Embase, and Web of Science were searched.

The p21 Ser31Arg polymorphism and breast cancer risk: a meta-analysis involving 51,236 subjects.

Published data on the association between p21 Ser31Arg polymorphism and breast cancer risk are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. Crude ORs with 95% CIs were used to assess the strength of association between the p21 Ser31Arg polymorphism and breast cancer risk.

Chemokine decoy receptor d6 plays a negative role in human breast cancer.

Chemokine binding protein D6 is a promiscuous decoy receptor that can inhibit inflammation in vivo; however, the role it plays in cancer is not well known yet. In this study, we showed for the first time that human breast cancer differentially expressed D6 and the expression could be regulated by some cytokines. More importantly, overexpression of D6 in human breast cancer cells inhibits proliferation and invasion in vitro and tumorigenesis and lung metastasis in vivo.
