CLINICAL DIAGNOSTICS
Biomarker Testing in Cancer

Biomarkers are genes, proteins, and other substances which can provide information about an individual’s cancer as each person has a unique pattern of biomarkers. They are also known as tumor markers. Some are cancer specific, whereas others may be associated with different cancer types. Some biomarkers provide diagnosis, some prognosis and some affect how certain cancer treatments work. Many different tumor markers have been characterized and are in clinical use.

Commonly tested Cancer Biomarkers with Prognostic/Predictive importance

Test CodeBiomarkerCancerImportance/Therapy
OG016IDH1 & 2AMLEnasidenib, Ivosidenib, Vorasidenib

OG035HER2 mutationsHer2+ Breast CancerHER2-positive patients carrying S310F, S310Y, R678Q, D769H, or I767M mutations are good candidates for anti-HER2 therapy. L755S or D769Y mutation also confer benefits when receiving Neratinib or Afatinib. Mutations L755S, V842I, K753I, or D769Y do not seem to benefit from Trastuzumab. Resistance to Lapatinib in patients with L755S, V842I, and K753I mutations
