Cohort of tumors with specific genetic mutations

Multicenter Prospective Cohort of Tumors With Pole/D1 Mutation

Federation Francophone de Cancerologie Digestive · NCT05103969

This study is looking at tumors with specific genetic changes in the POLE and POLD1 genes to better understand their characteristics and how they affect patients.

What this trial studies

This observational study aims to identify and describe the clinical, biological, and molecular characteristics of tumors with somatic mutations in the POLE and POLD1 genes. Patients will be identified through tumor genotyping platforms, which will provide data on new cases of mutated cancers. The study will collect diagnostic and follow-up data prospectively to better understand these specific tumor types. The focus is on tumors with pathogenic variants in the exonuclease domain of POLE and POLD1.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with tumors exhibiting pathogenic mutations in the POLE or POLD1 genes.

Not a fit: Patients with tumors that do not have POLE or POLD1 mutations will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of specific tumor mutations, leading to improved diagnosis and treatment strategies for affected patients.

How similar studies have performed: While this approach is focused on specific mutations, similar studies have shown promise in understanding the implications of genetic mutations in cancer.
