For the most effective use of Herceptin in breast cancer treatment,molecular testing for which of the following proteins should be performed before the drug is prescribed?

Question

Quizplus · Accepted Answer

Herceptin is a targeted therapy used in breast cancer treatment specifically for patients who have tumors that overexpress the HER2 protein. Therefore, molecular testing for HER2 should be performed before the drug is prescribed to ensure the most effective use. BRCA1 and BRCA2 testing may be relevant for assessing risk for developing breast cancer, but are not directly tied to Herceptin treatment. EGFR and MTHFR are not relevant to Herceptin treatment for breast cancer.
