EOD-Extension: If extension/metastasis is found within 4 months of diagnosis, but after first course of cancer-directed therapy has ended, should that involvement be excluded when coding the EOD-extension field? See discussion.
EOD-Extension: How is this field coded for synchronous primaries when metastatic disease is found and there is no statement to indicate which primary is the source of the metastases? See Description.
EOD-Extension: General instructions, page 7, note 3 states: " Extent of disease information obtained after treatment with neoadjuvant chemotherapy, hormone or immunotherapy has begun may be included." Because the SEER manual does not mention radiation treatment, can we use information from a lobectomy to code EOD if a patient has neoadjuvant radiation therapy?
EOD-Extension/SEER Summary Stage 2000--Kidney/Eye: What codes are used to represent these fields for simultaneous bilateral Wilms tumor or simultaneous bilateral retinoblastoma?
EOD-Extension/EOD-Lymph Nodes: Can the AJCC TNM/Stage be used to help code these fields when there is limited text information in the medical record that describes the tumor involvement?
EOD-Extension/EOD-Lymph Nodes--Testis: If the patient received chemo, should "bulky retroperitoneal adenopathy" be coded as involved lymph nodes in the EOD lymph node involvement field for a testicular primary treated with an orchiectomy that rendered a path diagnosis of "seminoma confined to the testicle"? See discussion.
EOD-Extension/EOD-Lymph Nodes--Rectosigmoid: How do you code these fields for a scan-based clinically staged T3 N1 rectosigmoid primary in a patient who received chemotherapy and radiation prior to a resection that demonstrated invasion only into the muscularis and no positive lymph nodes?
EOD-Extension/EOD-Lymph Nodes--Lung: Is "subcarinal extension" with no mention of lymph nodes coded in the EOD extension field or in the EOD lymph node involvement field? See discussion.
EOD-Extension/EOD-Lymph Nodes--Kaposi Sarcoma: What code is used to represent this field for a Kaposi sarcoma with no skin lesions but positive lymph node and bone marrow biopsies?
EOD-Extension/EOD-Lymph Nodes--Colon: For this primary, under which field are satellite tumor nodules in mesenteric adipose tissue coded? See Description.
