Inquiry Details

References:

2007 SEER Manual, C-844. Appendix C

Question:

Behavior--Bladder: What behavior code is used for a TURB path specimen diagnosis of "non-invasive urothelial carcinoma, no muscle found, depth of invasion cannot be assessed" when the clinician stages the case as Ta? See Discussion.

Discussion:

The SEER site specific coding module for bladder says, "If the only surgery performed is a TURB and if it is documented that depth of invasion cannot be measured because there is no muscle in the specimen, code the behavior as malignant and not in situ."

Answer:

Assign behavior code 2 [in situ] based on the physician's stage Ta.

When no other information is available and the TNM designation is not available, use the instructions on page C-844 in Appendix C of the 2007 SEER manual as a default.
