AFP (Alpha Fetoprotein) Pretreatment Interpretation
Description
AFP (Alpha Fetoprotein) Pretreatment Interpretation, a nonspecific serum protein that generally is elevated in the setting of hepatocellular carcinoma (HCC), is a prognostic factor for liver cancer. This data item pertains to the pre-treatment interpretation.
There are 2 related data items that record information on CEA for Colon and Rectum.
* 3810: AFP Pretreatment Lab Value
* 3809: AFP Pretreatment Interpretation
Rationale
AFP (Alpha Fetoprotein) Pretreatment Interpretation is a Registry Data Collection Variable in AJCC. This data item was previously collected for Liver, CS SSF #1.
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
**Normal Reference Range:**
* Adult men and non-pregnant women: 0-15 ng/ml (SI: 0-15 mg/L)
Notes
**Note 1:** **Physician Statement**
* Physician statement of AFP (Alpha Fetoprotein) Pretreatment Lab Value can be used to code this data item when no other information is available.
**Note 2:** **Pretreatment results only**
* Record the lab value of the highest AFP test result documented in the medical record prior to treatment. The lab value may be recorded 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 information in the related data item 3810: AFP Pretreatment Lab Value.
Coding Guidelines
**1)** Record the clinician’s interpretation of the highest value **prior to treatment**, based on the reference range used by the lab in the Interpretation data item.
* If the physician's statement is not available, use the **Reference Ranges** included in **Additional Information** for this data item to determine the interpretation
