Scope of Regional Lymph Node Surgery: If a named regional lymph node is aspirated should this field be coded to 1 [Regional lymph node removed, NOS], as is stated on page 127 of the SEER Program Code Manual, or should this field be coded to a more specific code when that is available (e.g. Lung primary code 3 [Ipsilateral mediastinal and/or subcarinal nodes])?
Scope of Regional Lymph Node Surgery: Should this field be coded to "unknown or not applicable" for all hematopoietic morphologies, brain primaries and unknown primaries?
Scope Regional LN Surgery--Melanoma: How is this field coded when there is no primary skin lesion and the only disease present is one axillary lymph node that reveals melanoma? See Discussion.
SEER Guidelines Over Time: Should we apply the current guidelines to previously missed older cases now being reported to the central registry? See discussion.
Sequence Number-central/Multiple Primaries (Pre-2007): What criteria are to be used to determine which primary site carries a worse prognosis? Should we take survival into consideration? See Discussion.
