Which of the Following Dictates the Use of Herceptin in Breast

Question

Which of the following dictates the use of Herceptin in breast cancer treatment?
A)If Herceptin is found in the breast lymph nodes of the patient.
B)If HER2, administered by injection, is in sufficient concentration.
C)If the patient's cancer cells have excessive levels of HER2.
D)If the patient's genome codes for the HER2 receptor.
E)If the patient's genome codes for the manufacture of Herceptin.

Accepted Answer

The use of Herceptin in breast cancer treatment is dictated by whether the patient's cancer cells have excessive levels of HER2. Herceptin targets and blocks the HER2 protein, which is present in high amounts in some breast cancers. Therefore, patients whose cancer cells have excessive levels of HER2 may benefit from Herceptin treatment.
