- Note 1: Record whether the tumor is unifocal or multifocal at initial diagnosis, for both resectable and unresectable cases. For unresectable cases, the information can be determined from radiological imaging studies or physician documentation).
- Note 2: Use code 001 when tumor is described as unifocal; arising from or occurring in a single focus or location.
- Note 3: The AJCC definition for multifocal tumor differs from the MP/H definition for Multiplicity Counter. Use code 002 for any tumor with multiple foci, even if foci are not measured.
