What this trial studies

This prospective biomarker study focuses on the use of liquid biopsy to enhance treatment outcomes for patients with metastatic cancer in community settings. Eligible participants include those with various tumor subtypes, specifically metastatic prostate cancer resistant to castration, triple-negative breast cancer, and hormone receptor-positive, HER2-negative metastatic breast cancer resistant to endocrine therapy. Plasma samples will be collected at baseline and after the first radiologic assessment to analyze genetic markers and circulating DNA. The findings will be reviewed by a Molecular Tumor Board to guide treatment decisions.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with locally advanced or metastatic solid tumors, including specific types of breast and prostate cancers.

Not a fit: Patients with symptomatic or progressive brain metastases or those with other malignancies within the last five years may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more personalized and effective treatment options for patients with metastatic cancer.

How similar studies have performed: Other studies utilizing liquid biopsy for cancer treatment have shown promising results, indicating potential for success in this approach.
