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
