AFP Post-Orchiectomy Range (Testis)

Note 1 Physician statement of the AFP (Alpha Fetoprotein) Post-Orchiectomy Range can be used to code this data item when there is no other information available.

Note 2 Record the range of the AFP test as documented in the medical record after orchiectomy but prior to adjuvant therapy. The lab value may be documented in a lab report, history and physical, or clinical statement in the pathology report.

Note 3 If the initial post-orchiectomy AFP remains elevated, review subsequent tests and record the lowest AFP value (normalization or plateau) prior to adjuvant therapy or before the value rises again.

Note 4 A lab value expressed in micrograms/liter (ug/L) is equivalent to the same value expressed in nanograms/milliliter (ng/mL).

Note 5 If the lab value is expressed in IU/ml, use the following conversion 1 ng/mL = 0.83 IU/mL.

• To calculate ng from IU/mL, divide the value for IU by 0.83.
• Example 10 IU/mL 10/0.83 = 12.04 ng/mL; 5 IU/mL 5/0.83= 6.02 ng/mL

Note 6 If the pre-orchiectomy AFP was normal, a post-orchiectomy AFP may not be performed. In this case, code 5 should be recorded.

Note 7 The same laboratory test should be used to record information in AFP Post-Orchiectomy Lab Value (NAACCR Data Item #3805).
