Por que realizar este exame?

Irinotecan is an analogue of camptothecin, an approved drug for the treatment of advanced colorectal cancer, and also for lung, brain and breast tumors. A genetic variant in the TATA element has been described in the promoter of the UGT1A1 gene, which may produce a decrease in the expression of the UGT1A1 gene, and, therefore, protein synthesis (the enzyme UGT1A1). Decreased levels of the UGT1A1 enzyme may produce accumulation of the active metabolite SN-38, and consequently the adverse effects and toxicity associated with treatment with irinotecan.

O que é o exame?

The genetic profile FG – Onco Irinotecan studies the main allelic variants of the UGT1A1 gene with known clinical relevance. The efficacy and toxicity of drugs depends largely on genes and genetic variants among individuals.
