Biomarker analysis for metastatic leiomyosarcoma patients

Observational Study of Biomarkers of Disease-related Outcomes in Patients With Metastatic Leiomyosarcoma Receiving Chemotherapy

Observational University of Michigan Rogel Cancer Center · NCT05653388

This study is trying to see if blood and tissue samples can help find markers that show how well chemotherapy is working for patients with advanced leiomyosarcoma.

What this trial studies

This observational study focuses on patients with unresectable or metastatic leiomyosarcoma who are receiving first-line chemotherapy. It aims to collect and analyze blood samples for circulating tumor DNA (ctDNA) to identify potential biomarkers that could indicate tumor response and patient survival benefits from chemotherapy. Additionally, tumor tissue samples will be collected to investigate genetic mutations associated with sarcoma. The goal is to enhance treatment planning by identifying early indicators of treatment efficacy.

Who should consider this trial

Good fit: Ideal candidates are patients with unresectable or metastatic leiomyosarcoma who are starting first-line chemotherapy with doxorubicin or gemcitabine/docetaxel.

Not a fit: Patients with resectable leiomyosarcoma or those not receiving the specified chemotherapy regimens may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for patients with metastatic leiomyosarcoma by identifying effective biomarkers.

How similar studies have performed: Other studies have shown promise in using ctDNA as a biomarker in various cancers, suggesting potential success for this approach in leiomyosarcoma.
