Question:

EOD-Extension: If extension/metastasis is found within 4 months of diagnosis, but after first course of cancer-directed therapy has ended, should that involvement be excluded when coding the EOD-extension field? See discussion.

Discussion:

Example: Spinal drop metastasis was diagnosed within 4 months of the initial diagnosis of a localized astrocytoma, but after treatment with surgery and XRT was completed.

Answer:

For cases diagnosed 1998-2003:

Do not include the spinal metastasis because it was diagnosed after the extent of disease was established. If metastasis was not present at diagnosis, and not discovered during the original metastatic work-up, it is progression of disease.
