Chromosome 3 Status
Notes
**Note 1:** Physician statement of chromosome 3 status can be used to code this data item when no other information is available.
**Note 2:** Monosomy 3, especially if combined with a frequently coexisting gain in chromosome 8q, is independently associated with metastatic risk. Chromosome 3 and 8 statuses may be determined with karyotyping or fluorescent in situ hybridization (FISH).
**Note 3:** See also 3822: Chromosome 8q Status.
