Native American have been diagnosed with Ovarian cancer. Do the biomarker testing work for my ethnicity

I understand your important question about biomarker testing and ethnicity. Let me provide some evidence-based information:

According to the Society of Gynecologic Oncology (SGO) and NCCN Guidelines (2023), biomarker testing is recommended for ALL ovarian cancer patients regardless of race or ethnicity, specifically for:

• BRCA1/BRCA2 mutations
• Homologous Recombination Deficiency (HRD) status
• Microsatellite Instability (MSI) testing

However, there are some important considerations for Native American patients:

The American Society of Clinical Oncology (ASCO) guidelines (2023) note that:

• Most genetic research historically has included limited diversity
• Some genetic variants may be more common or different in Native American populations
• It's important to work with genetic counselors who understand diverse populations

The National Cancer Institute (NCI) recommends:

• Informing your healthcare team about your Native American heritage
• Considering genetic counseling before and after testing
• Asking about laboratories that include diverse population databases in their testing

Important recommendations:

1. Request a referral to a genetic counselor experienced with Native American populations
2. Ask about comprehensive biomarker testing panels
3. Discuss with your doctor how the results will guide your treatment options

Always remember that biomarker testing is still valuable and recommended for all ethnic groups, but interpretation may need special consideration. Please discuss any specific concerns with your healthcare team.
