AFP (Alpha Fetoprotein) Pre-Orchiectomy Range
Description
AFP (Alpha Fetoprotein) Pre-Orchiectomy Range identifies the range category of the highest AFP value measured prior to treatment. AFP is a serum tumor marker that is often elevated in patients with nonseminomatous germ cell tumors of the testis.
For Testis, there are 4 related data items that record information on AFP for Testis.
* 3805: AFP Post-Orchiectomy Lab Value
* 3806: AFP Post-Orchiectomy Range
* 3807: AFP Pre-Orchiectomy Lab Value
* 3808: AFP Pre-Orchiectomy Range
Rationale
AFP (Alpha Fetoprotein) is a Registry Data Collection Variable in AJCC. AFP (Alpha Fetoprotein) Pre-Orchiectomy Range is used to assign the S Category Clinical and was previously collected as Testis CS SSF #7.
Additional Info
**Source documents:** clinical laboratory report (blood serum radioimmunoassay or enzyme assay (EIA)); sometimes in history and physical or clinical statement in pathology report
**Other names include** AFP, aFP, Alpha Fetoprotein, Alpha-fetoprotein, alpha-fetoprotein, fetal alpha globulin
For further information, refer to the **Testis** cancer protocol published by the College of American Pathologists for the AJCC Staging System *Testis*
**Normal Reference Range**
* Adult men 0-15 ng/ml (SI: 0-15 µg/L)**
**Measurements**
* A lab value expressed in micrograms/liter (ug/L) is equivalent to the same value expressed in nanograms/milliliter (ng/mL).
* ***Example***: 10 IU/mL: 10/0.83 = 12.04 ng/mL; 5 IU/mL: 5/0.83= 6.02 ng/mL
* 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
Notes
**Note 1:** **Physician Statement**
* Physician statement of the AFP (Alpha Fetoprotein) Pre-Orchiectomy Range can be used to code this data item when no other information is available.
**Note 2:** **Timing**
* Record the range of the highest AFP test result documented in the medical record **prior to orchiectomy** or prior to any systemic treatment. The lab value may be documented in a lab report, history and physical, or clinical statement in the pathology report.
**Note 3:** **Related data item**
* The same laboratory test should be used to record the related data item 3807: AFP Pre-Orchiectomy Lab Value.
