Inquiry Details

2004 SEER Manual, 190. #2
Question:
Chemotherapy: If a physician does not document the reason chemotherapy was given concurrently with radiation therapy, should it be assumed to have been used as a radiosensitizer or radioprotectant and then, per SEER chemotherapy coding instruction 2, ignore coding the chemo agent as treatment?
Discussion:
Answer:
Do not assume that a chemo agent given with radiation therapy is a radiosensitizer. Seek additional information.
Compare the dose given to the dose normally given for treatment. When chemotherapeutic agents are used as radiosensitizers or radioprotectants, they are given at a much lower dose.
