hCG (Human Chorionic Gonadotropin) Post-Orchiectomy Range
Description
Human Chorionic Gonadotropin (hCG) Post-Orchiectomy Range identifies the range category of the lowest hCG value measured post-orchiectomy. hCG is a serum tumor marker that is often elevated in patients with nonseminomatous germ cell tumors of the testis. The post-orchiectomy lab value is used to monitor response to therapy.
For Testis, there are 4 related data items that record information on hCG.
* 3846: hCG Post-Orchiectomy Lab Value
* 3847: hCG Post-Orchiectomy Range
* 3848: hCG Pre-Orchiectomy Lab Value
* 3849: hCG Pre-Orchiectomy Range
Rationale
hCG (Human Chorionic Gonadotropin) is a Registry Data Collection Variable in AJCC. hCG (Human Chorionic Gonadotropin) Post-orchiectomy Range is used to assign the S Category Pathological and was previously collected as Testis CS SSF #15.
Additional Info
**Source documents:** clinical laboratory report (blood or serum test), sometimes in history and physical or clinical statement in pathology report
**Other names include** Human chorionic gonadotropin, b-hCG, beta subunit HCG, beta hCG, -hCG•
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**
* < 2 ng/ml (SI: < 2 µg/L or < 2 ug/L) 1 ng/ml of HCG is approximately 5 mIU/ml.
* < 5 mIU/mL (< 5 IU/L) To record mIU/mL in ng/ml, divide the test result by 5.
**Measurements**
* A lab value expressed in International Units/liter (IU/L) is equivalent to the same value expressed in milli-International Units/milliliter (mIU/mL).
Notes
**Note 1:** **Physician Statement**
* Physician statement of the hCG (Human Chorionic Gonadotropin) Post-Orchiectomy Range can be used to code this data item when there is no other information available.
**Note 2:** **Timing**
* Record the range of the hCG 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:** **Lab values elevated after orchiectomy**
* If the initial post-orchiectomy hCG remains elevated, review subsequent tests and record the lowest hCG value (normalization or plateau) prior to adjuvant therapy or before the value rises again.
**Note 4:** **Pre-orchiectomy hCG normal**
* If the pre-orchiectomy hCG was normal, a post-orchiectomy hCG may not be performed. In this case, code 5 should be recorded.
**Note 5:** **Related Data Item**
* The same laboratory test should be used to record the related data item 3846: hCG Post-Orchiectomy Lab Value.
