Multimodal Liquid-Biopsy Omics Biomarkers of Treatment Response in Breast Cancer
Exploration of Treatment-Response Biomarkers in Breast Cancer Based on Integrated Liquid-Biopsy Multimodal Omics Features
This single-center cohort study integrates humoral immune response profiling (Phage ImmunoPrecipitation Sequencing, PhIP-seq) with circulating cell-free DNA (cfDNA) genomic and epigenomic features, exosome transcriptomics, and plasma metabolomics to discover and validate liquid-biopsy biomarkers of treatment response in breast cancer.
The study comprises four cohorts: (1) a retrospective pan-cancer cohort of approximately 1,000 patients with solid malignant tumor, using archived residual serum/plasma to construct a pan-cancer antigen repertoire and cfDNA mutational/methylation atlas, with priority given to patients who had available Whole Exome Sequencing (WES) data; (2) a prospective cohort of 800 women with non-metastatic (M0) breast cancer receiving standard neoadjuvant chemotherapy (NAC); (3) a prospective cohort of 100 women with metastatic (M1) breast cancer receiving standard systemic therapy; and (4) a control group of 100 individuals, including patients with benign breast disease (breast fibroadenoma) and healthy volunteers.
The primary objective is to identify biomarkers-autoantibody repertoires, cfDNA mutation clearance, methylation reprogramming, exosome transcripts, and metabolic signatures-associated with pathological complete response (pCR) to NAC, and to develop predictive models where feasible.

Szczegółowy opis
Peripheral blood (20 mL) is collected at protocol-defined time points. Serum/Plasma autoantibody repertoires are profiled by PhIP-seq(phage-display immunoprecipitation sequencing); cfDNA methylation is measured by bisulfite-free methylome profiling; exosome RNA is profiled by strand-specific RNA sequencing; and untargeted plasma metabolomics is performed by liquid chromatography-tandem mass spectrometry. The study endpoints include clinical response and pathological complete response after NAC, together with survival follow-up. The study is conducted in accordance with the Declaration of Helsinki and Chinese regulations for investigator-initiated research, and has been approved by the institutional ethics committee.
Ambispective - a retrospective pan-cancer cohort (archived samples, 2020 Jan - 2026. Sep) combined with prospective breast cancer cohorts (enrollment 2026. Oct -2029)

Retrospective Pan-Cancer Cohort
Patients aged 18-80 years with histologically confirmed solid malignant tumors( e.g. non-small cell lung cancer, colorectal cancer, gastric cancer, hepatocellular carcinoma, or breast cancer), diagnosed at the study site between January 2020 and Sep 2026, with complete clinical data (TNM stage and treatment plan) and archived residual serum/plasma samples. Approximately 1,000 cases. |
|
Prospective Neoadjuvant Chemotherapy (NAC) Breast Cancer Cohort
Women aged 18-80 years with clinically and pathologically confirmed non-metastatic (M0) breast cancer who plan to receive standard NAC at the study site, with complete pre-treatment ER, PR, and HER2 immunohistochemistry results. Planned enrollment: 800. Peripheral blood (20 mL) is collected before, during, and after NAC (pre-surgery), in addition to routine clinical data. |
|
Prospective Benign/Control Group (Breast Fibroadenoma or Healthy Volunteers)
Patients with breast fibroadenoma undergoing minimally invasive biopsy during the same period, serving as benign controls to calibrate background signals of circulating antigens and liquid-biopsy analytes. Healthy female volunteers will also be enrolled. Planned enrollment: 100. |

Prospective Metastatic Breast Cancer Cohort
Women aged 18-80 years with clinically and pathologically confirmed metastatic (M1) breast cancer who plan to receive standard systemic therapy at the study site, with complete ER, PR, and HER2 immunohistochemistry results.Planned enrollment: 100. Serial peripheral blood samples are collected before, during, and after treatment. |
