Trastuzumab is used to treat breast cancer. It is effective against tumors that overexpress the HER2/neu protien. As part of chemotherapy regimen for adjuvant treatment of lymph-node positive, HER2/neu positive cancer.
Indications
The introduction of herceptin (Trastuzumab) into clinical
practice for the treatment of breast cancer marks a
major advance in the use of monoclonal antibody cancer
therapy. Herceptin is a humanized antibody directed
against the HER-2 antigen that is overexpressed
on the tumor cell surface in approximately 25% of
breast cancer patients. HER-2/neu/erbB2 overexpression
marks an aggressive estrogen receptor–negative
form of breast cancer. Therefore, a therapeutic agent
selective for this target is particularly valuable.
Herceptin is administered by intravenous infusion and
in conjunction with paclitaxel can extend survival in
patients with HER-2/neu/erbB2 overexpressing metastatic
breast cancer.Herceptin use is associated with infusion-
related hypotension, flushing and bronchoconstriction,
and skin rash but no bone marrow toxicity.
Herceptin appears to sensitize patients to cardiotoxicity,
an important concern in patients also receiving
doxorubicin.
