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--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--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: 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/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: 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: 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: 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: There is a one to many relationship between T values in TNM staging and SEER EOD-Extension values (one T value can be coded to many extension values). For most situations, we can typically code EOD-Extension to the lowest value in the range available for that T value per the SEER guidelines. But, what happens if another tumor feature, such as tumor size, was involved in the assignment of a T value? See discussion.
EOD-Lymph Nodes--Breast: Are lymph nodes described as being either "keratin positive" or "keratin positive for metastasis" to be coded as involved lymph nodes?
