First course treatment--Corpus Uteri: Should Arimidex be coded as hormone therapy for an endometrioid adenocarcinoma? See Discussion.
Per the SEER Manual, endometrial cancers may be treated with progesterone which is coded as hormone therapy for these primaries. As endometrioid adenocarcinomas are hormonally-dependent carcinomas, should an aromatase inhibitor or anti-estrogen agent also be coded as hormone therapy?
Arimidex has not been approved to treat endometrial cancer. It is not prescribed for pre-menopausal women. Clarify with the physician why the drug was being used. If the physician states Arimidex was given to reduce tumor burden, code as hormone therapy.
