Qiao Li: Influence Statistics

BackgroundEpithelial–mesenchymal transition (EMT) is implicated in the metastatic process and presents a challenge to epithelial cell adhesion molecule-based detection of circulating tumor cells (CTCs), which have been demonstrated to be a prognostic indicator in metastatic breast cancer. Although evidence has indicated that heterogeneity of CTCs based on EMT markers is associated with disease progression, no standard recommendations have been established for clinical practice. This ...

Purpose This phase I study assessed the safety, tolerability, pharmacokinetics, antitumor activity, and predictive biomarkers of pyrotinib, an irreversible pan-ErbB inhibitor, in patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer. Patients and Methods Pyrotinib was administered continuously, orally, once per day to patients who did not have prior exposure to tyrosine kinase inhibitors of HER2. Planned dose escalation was 80, 160, 240, 320, ...

PURPOSE: This phase I study assessed the safety, tolerability, MTD, pharmacokinetics, antitumor activity, and predictive biomarkers of pyrotinib, an irreversible pan-ErbB inhibitor, in combination with capecitabine in patients with HER2-positive metastatic breast cancer (MBC).

PATIENTS AND METHODS: Patients received oral pyrotinib 160 mg, 240 mg, 320 mg, or 400 mg once daily continually plus capecitabine 1,000 mg/m2 twice daily on days 1 to 14 of a 21-day cycle. Pharmacokinetic blood ...

BACKGROUND: Cisplatin is an effective agent for triple-negative breast cancer (TNBC) and synergistic activity between cisplatin and capecitabine has been demonstrated by in vitro and in vivo studies. This study was designed as a prospective clinical trial to evaluate the efficacy and safety of capecitabine plus cisplatin (XP) regimen in metastatic TNBC patients pretreated with anthracyclines and taxanes.

PATIENTS AND METHODS: Thirty-three patients with metastatic TNBC who had ...

AIMS: This phase II study prospectively evaluated the feasibility of vinorelbine in combination with capecitabine in Chinese patients with metastatic breast cancer (MBC) pretreated with anthracyclines and taxanes.

METHODS: Vinorelbine (25 mg/m(2) intravenous infusion on days 1 and 8) and capecitabine (1,000 mg/m(2) b.i.d., days 1-14) were administered to eligible MBC patients previously treated with anthracyclines and taxanes every 3 weeks for up to 6 cycles, until disease progression or ...

Tumor heterogeneity was associated with treatment outcome of metastatic cancers but few studies have examined whether tumor heterogeneity in circulating tumor DNA (ctDNA) can be used to predict treatment outcome. ctDNA analysis was performed in 37 HER2-positive metastatic breast cancer patients treated with pyrotinib. Patients with high tumor heterogeneity had significantly worse PFS outcomes, with a median PFS of 30.0 weeks vs. 60.0 weeks for patients with low tumor heterogeneity ...

Toremifene (TOR) is a valid and safe alternative to tamoxifen (TAM) for adjuvant endocrine therapy in breast cancer patients with a metabolic pathway that differs from that of TAM. TOR might have a therapeutic advantage in certain subgroups of patients, such as Chinese women with the CYP2D6 *10 (c.100C > T) T/T genotype, who would get less benefit when receiving adjuvant TAM treatment. A total of 230 breast cancer patients who received adjuvant TAM (n = 115) or TOR (n = 115) at the ...

The aim of the study was to determine the predictive role of breast cancer subtypes in the efficacy and prognosis of neoadjuvant chemotherapy (NCT) regimens combining taxanes and anthracyclines.Data from 240 patients with breast cancer who received surgery after 4 to 6 weeks of NCT were retrospectively analyzed. The patients were classified into luminal A, luminal B, HER2 overexpression, and triple negative breast cancer (TNBC) as well as low Ki67 (≤ 14%) and high Ki67 (> 14%) expression ...

BACKGROUND: Most studies utilizing circulating tumor DNA (ctDNA) to monitor disease interrogated only one or a few genes and failed to develop workable criteria to inform clinical practice. We evaluated the feasibility of detecting resistance to anti-HER2 therapy by serial gene-panel ctDNA sequencing.

RESULTS: Primary therapeutic resistance was identified in 6 out of 14 patients with events of progressive disease. For this subset comparison of pre- and post-treatment ctDNA assay results ...

Variants of the CYP2D6 gene may lead to a poor prognosis of tamoxifen (TAM)-treated patients. Our study validated the association between the CYP2D6 genotype and outcomes of patients receiving TAM in adjuvant endocrine therapy. A total of 778 breast cancer patients who received adjuvant TAM (n = 325) or aromatase inhibitors (AIs) (n = 453) at the National Cancer Center were analyzed. Nine single nucleotide polymorphisms (SNPs) in the CYP2D6 gene were selected from online databases. The ...

BACKGROUND: There is a lack of prognostic models predicting the overall survival (OS) of advanced breast cancer (ABC) patients in China.

METHODS: Data from the China National Cancer Center database that recorded 4039 patients diagnosed with breast cancer between 1987 and 2019 were extracted and a total of 2263 ABC participants were enrolled in this study, which were further randomized 3:1 and divided into training (n = 1706) and validation (n = 557) groups. The nomogram was built based ...

PurposeThe Chinese bridging study PUFFIN (NCT02896855) aimed to assess consistency of efficacy with CLEOPATRA (NCT00567190), investigating pertuzumab with trastuzumab and docetaxel versus placebo, trastuzumab, and docetaxel in patients with previously untreated HER2-positive locally recurrent or metastatic breast cancer.MethodsPatients were randomized 1:1, stratified by visceral/non-visceral disease and hormone receptor status. The primary endpoint was investigator-assessed ...

BackgroundBreast cancer is a global problem, and a large number of new cases are diagnosed every year. Capecitabine is effective in patients with metastatic breast cancer (MBC). Hand-foot syndrome (HFS) is a common adverse effect of capecitabine. In this study, we investigated the association between single nucleotide polymorphisms (SNPs) in genes involved in capecitabine metabolism pathways and capecitabine-induced HFS in Chinese patients with MBC to identify some predictive genetic ...

The risk factors for morbidity and mortality in patients with breast cancer liver metastases (BCLM) upon initial metastatic breast cancer (MBC) diagnosis have not been adequately identified in Han population. Data of 3,161 female patients who were initially diagnosed with MBC from December 1991 to September 2019 and treated in the China National Cancer Center were extracted and a total of 2,263 MBC patients were included in our study, among which 550 patients had liver metastases. ...
