Reportability/MP/H Rules/Multiple primaries: Is a ganglioneuroblastoma (9490/3) following a melanoma (8720/3) a new primary if the diagnosing pathologist states:  ‘Given the clinical context and patient age, then I believe that this may represent transdifferentiation of metastatic melanoma’?  If this is a new primary, what MP/H rule would apply?  See Discussion.

Scope of Regional Lymph Node Surgery--Lung:  How do you code Regional Nodes Positive, Regional Nodes Examined, and Scope of Regional Lymph Node Surgery when a fine needle aspirate (FNA) or biopsy of supraclavicular lymph nodes is positive for a lung cancer primary?  Supraclavicular lymph nodes are distant in SEER Summary Stage and regional by AJCC.  See Discussion.

Final Dec 06 2017

First Course Treatment: Should the definition in the 2016 SEER Coding Manual be revised for first course of treatment following disease progression for patients who complete the initial first course treatment plan without alteration but had one or more treatment modalities given after disease progression was identified?
