Personalized mutation tracking in circulating-tumor DNA predicts recurrence in patients with high-risk early breast cancer.

The clinical utilization of circulating tumor DNA (ctDNA) in breast cancer (BC) management is not well-defined. In this prospective study, 168 patients with early-stage BC were recruited, serial blood samples were collected before and after surgery. Tumor-informed ctDNA testing was performed, which sequenced tumors for 95 genes followed by bespoke mPCR to track 1-9 mutations in the plasma.

Tumor genomic profiling and personalized tracking of circulating tumor DNA in Vietnamese colorectal cancer patients.

Background: Colorectal cancer (CRC) is the fifth most common cancer with rising prevalence in Vietnam. However, there is no data about the mutational landscape and actionable alterations in the Vietnamese patients. During post-operative surveillance, clinical tools are limited to stratify risk of recurrence and detect residual disease.

Genetic landscape and personalized tracking of tumor mutations in Vietnamese women with breast cancer.

Breast cancer is the leading cause of cancer death in Vietnamese women, but its mutational landscape and actionable alterations for targeted therapies remain unknown. After treatment, a sensitive biomarker to complement conventional imaging to monitor patients is also lacking. In this prospective multi-center study, 134 early-stage breast cancer patients eligible for curative-intent surgery were recruited.
