Question:

MP/H Rules: Does the presence of metastases affect the application of the MP/H rules? See Discussion.

Discussion:

Single lung tumors presenting in each lung but the patient also presents with bone mets? Would rule M6 apply? Or do the bone mets represent additional tumors?

Answer:

For cases diagnosed 2007 or later, the MP/H rules do not apply to metastases. Ignore metastases when applying the rules.

For the case above, use rule M6 and abstract as two primaries (right lung and left lung). The bone mets are ignored.
