研究概览
简要总结
A prospective, multicenter, observational study to evaluate the correlation of Molecular Residual Disease (MRD) detection using circulating tumor DNA guided test to pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) in stage I-III triple negative breast cancer (TNBC). Results from this study aim to improve MRD detection and disease outcomes for future patients.
详细描述
NeXT Personal CTA (Clinical Trial Assay) is a patient-specific, tumor-informed device which allows for detection of MRD from cfDNA. By using next generation sequencing technology, whole genome sequencing (WGS) is conducted from DNA derived from patient tumor and normal samples. A tumor informed personalized panel is then constructed that uses only a selection of DNA targets from the WGS by applying bioinformatic filters. The targeted personalized panel is then sequenced using NGS and DNA derived from cfDNA from plasma samples. The data from the cfDNA NGS are then further analyzed using bioinformatics filters to report the MRD status.

结局指标
主要结局
Evaluate the correlation of MRD to pCR after NAC in TNBC
时间窗: through study completion, an average of 6 months
Evaluate the correlation of MRD detection by NeXT Personal CTA to pathological Complete Response (pCR) after neoadjuvant chemotherapy (NAC) in stage I-III triple negative breast cancer (TNBC). The pCR is defined as the absence of residual invasive cancer on hematoxylin and eosin evaluation of the complete resected breast specimen and all sampled regional lymph nodes following completion of neoadjuvant systemic therapy.
次要结局
- Evaluate the trajectory of changes in MRD to pCR or non pCR in TNBC(through study completion, an average of 6 months)
