Identifying genetic factors in early-onset cancer using exome analysis

EXOME Analysis Position in the Strategy of Genetic Predisposition Factors Identification in Early-onset Cancer

Not applicable Interventional Centre Georges Francois Leclerc · NCT04141462

This study is trying to find new genetic clues in patients with early-onset cancer who didn't get answers from previous tests to help improve how we understand and diagnose these cancers.

What this trial studies

This study aims to evaluate the effectiveness of high-throughput exome sequencing (SHD-E) in identifying genetic predisposition factors in patients diagnosed with early-onset cancer, either sporadic or familial. It focuses on patients who have previously undergone a gene panel analysis that yielded negative results, suggesting that traditional methods may not capture all relevant genetic alterations. By analyzing blood samples and potentially tumor samples, the study seeks to uncover additional genetic mutations that could contribute to cancer development. The goal is to enhance the understanding of genetic factors involved in early-onset cancers and improve diagnostic strategies.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with cancer before age 40, who have undergone a negative oncogenetic panel and have available family members for genetic analysis.

Not a fit: Patients with known genetic mutations identified in the oncogenetic panel or those diagnosed with cancer after age 40 may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better identification of genetic predispositions in early-onset cancer patients, allowing for more personalized treatment and prevention strategies.

How similar studies have performed: Other studies utilizing high-throughput exome sequencing have shown promise in identifying genetic factors in various cancers, suggesting that this approach may be effective.
