Question:

EOD-Pathologic Extension--Prostate: Is extracapsular extension implied by the following phrases: "case staged as C" and "case staged as T3a"? See discussion.

Discussion:

Example: A prostatectomy was done on 6/29. The physician staged the case as a "C" on 7/2 and as T3a on 8/6. It appears the physician is interpreting the following pathology information as unilateral extracapsular extension: "The tumor on the right extends to the inked surface of the gland. In this area the capsule appears absent." Should pathologic extension be coded to unilateral extracapsular extension [42]?

Answer:

For cases diagnosed 1998-2003:

Yes. Use the best information available to stage this case. In this case, the best information is the physician's statement that the case is stage T3a. Without any additional information, the EOD-Extension field is coded to 42 [Unilateral extracapsular extension (pT3a)] on the basis of the T3a stage by the MD. When there is a conflict between different staging systems, default to the AJCC stage.
