Measured Thickness/EOD-Extension--Melanoma: If the Clark's level is not provided, can it be estimated using the depth of invasion provided in the pathology report and associating that number with the Clark's levels identified in the SEER Summary Staging Guide?
Primary Site--Breast: Is there a hierarchy for coding subsite for breast cases when there is conflicting information in the physical exam, mammogram, operative and pathology reports as to the exact location of the primary? See discussion.
Ambiguous Terminology: Should SEER's lists of ambiguous terminology be modified to reflect how pathologists and radiologists actually use these terms? See discussion.
EOD-Size of Primary Tumor--Prostate: When there are multiple nodules in the prostate, can size of tumor be based on the size of the largest nodule? See discussion.
EOD-Clinical Extension/EOD-Lymph Nodes--Prostate: How do you code clinical extension and lymph nodes for path only prostate cases treated with a TURP? Would clinical extension be coded to unknown or localized, NOS?
EOD-Extension--Lymphoma: What code is used to represent a non-Hodgkin lymphoma presenting with involvement of an extralymphatic organ and lymph nodes on the opposite side of the diaphragm?
EOD-Size of Primary Tumor--Breast: When the pathology report does not specify dimensions for the invasive component, how is tumor size coded? See discussion.
