Question:

First Course Treatment/Radiation Therapy/Immunotherapy--Thyroid: For this primary, do we code I-131 as a Radio-isotope as well as a Biological Response Modifier? See Description.

Discussion:

(SEER Book 8 lists I-131 as a Biological Response Modifier.) Immunoglobulin is listed as immunotherapy agent in the CCR manual also coded as immunotherapy. Are there two different types of I-131, immunoglobulin and sodium iodide?

Answer:

Code Radioactive Iodine, Sodium Iodide 131-I, as radiation (code 3, Radioisotopes).

Sodium Iodide is listed as an ancillary drug in SEER Book 8, page 45. The listing on page 63 refers to Antiferritin antibody, or AntiCEA. Both of these were under clinical investigation when Book 8 was written. They are no longer active and this change will be made when Book 8 is revised.
