Although these generic terms are not "good" diagnoses according to the pathologists, they are quite prevalent on cytology reports and death certificates, so we needed a place for them in ICD-O-3.
Stem cell leukemia had a code in ICD-O-1 and it has been returned to ICD-O-3.
NOS = Not Otherwise Specified
|8046/3||Non-small cell carcinoma, NOS|
|8935/3||Stromal sarcoma, NOS|
|9591/3||B-cell lymphoma, NOS|
|9702/3||T-cell lymphoma, NOS|
|9801/3||Stem cell leukemia|
|9860/3||Non-lymphocytic leukemia, NOS|
It is hoped (and suggested) that these codes will be used to mark cases for more in-depth analysis later to find a more precise diagnosis.
