Inquiry Details

#1: SEER EOD-88, 3rd Ed, 2
#2: 2004 SEER Manual, 123
Question:
Terminology/Terms of involvement: When the terms "lytic" or "lysis" are used in an imaging study, are they to be interpreted as synonymous with metastasis, or can these terms be used to describe a non-malignant condition?
Discussion:
Answer:
Although the term "lytic lesion" is often used to describe bone lesions and "tumor lysis" develops in response to systemic therapy, the words are not a part of the SEER list of terms used to describe involvement. Do not code distant metastasis based only on these words.
