FG Onco Lapatinib

Pharmacogenetics of lapatinib treatment

Why undergoing this examination?

Lapatinib is a medication used in the chemotherapy of breast cancer and other solid tumors. It belongs to the group of kinase inhibitors, which act by blocking the action of the abnormal protein that signals tumor cells to multiply. Several scientific studies show that different HLA (human leukocyte antigen) polymorphisms within the major histocompatibility complex (MHC) are strongly associated with the hepatotoxicity of lapatinib treatment. This hepatotoxicity can appear within a few days or several months after the start of treatment. 

What is this exam?

The FG Onco Lapatinib genetic profile evaluates whether the patient carries the HLA alleles DQA102:01 and DRB107:01. The purpose of the test is to identify those patients with an increased risk of developing serious side effects, especially hepatotoxicity, during lapatinib treatment. 

For whom is it indicated?

  • Patients undergoing pharmacological treatment that does not yield expected results; 
  • Patients experiencing drug-related side effects.
