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.
