Question:

MP/H rules/Multiple primaries: Is a 2007 cytology diagnosis of adenocarcinoma in bile duct a new primary for a patient with a 2005 diagnosis of adenocarcinoma of gallbladder? See Discussion.

Discussion:

A case abstracted for an adenocarcinoma of gallbladder (C23.9) in 2005. In 2007, cytology diagnosis of adenocarcinoma in bile duct(C24.0). Oncologist calls this recurrence. There is no pathologist statement of recurrence.

Using Other Sites multiple primary rules, rule M10 indicates this is multiple primaries. Sequence 01 dx in 2005 and sequence 02 dx in 2007. Is this correct? There is no statement of a primary tumor; the MP/H rules talk in terms of mass, lesion, tumor in a primary site.

Answer:

For cases diagnosed 2007 or later, abstract the 2007 bile duct diagnosis as a new primary unless it is described as metastatic.
