Identifying genetic factors in early-onset cancer using exome analysis
Official title: EXOME Analysis Position in the Strategy of Genetic Predisposition Factors Identification in Early-onset Cancer
Run by Centre Georges Francois Leclerc · NCT04141462 · Data updated 2026-11-12
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.

Is this trial a fit for you?
✓Likely a 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.
✕Probably 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.

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