EOD 2018/Primary Tumor--Breast: We are having difficulty deciding when we can or cannot use physician-assigned TNM staging to code EOD data items if the medical record or hospital abstract documentation is unclear. As a central registry, we are unable to query physicians for clarification. Please advise what is a “discrepancy” in the EOD General Instructions to “Use the medical record documentation to assign EOD when there is a discrepancy between the T, N, M information and the documentation in the medical record.” See Discussion.

EOD 2018/Prostate Pathologic Extension--Prostate: Is a pathology report from a prostate biopsy/transurethral resection of the prostate that states "with intraductal spread" extraprostatic/extracapsular extension or localized?

EOD 2018/Regional Nodes--Breast: Should Extent of Disease (EOD) Regional Nodes be coded as 150 (Clinical assessment only; Positive needle core biopsy/fine needle aspirate [FNA]) when the patient has a biopsy-proven, clinically apparent, movable ipsilateral axillary lymph node, but no evidence of involvement at surgery after neoadjuvant therapy? See Discussion.

EOD 2018/Regional Nodes--Corpus Uteri: Are lymph nodes found on imaging post-surgery included in Extent of Disease (EOD) Regional Nodes if surgery is already completed? See Discussion.

EOD 2018/Regional Nodes--Liver: Are the celiac axis lymph nodes considered regional lymph nodes or distant lymph nodes for a 2025 liver primary?

EOD 2018/Summary Stage 2018--Brain and CNS: What are the Extent of Disease (EOD) Primary Tumor, EOD Regional Nodes, and Summary Stage 2018 codes for intradural schwannoma of the lumbar spine (L2-L4)? See Discussion.

EOD 2018/Summary Stage 2018--GIST: How should Extent of Disease (EOD) and Summary Stage be coded for a multifocal gastrointestinal stromal tumor (GIST)? See Discussion.

EOD 2018/Summary Stage 2018--Intrahepatic Bile Duct: How should Extent of Disease (EOD) Primary Tumor (PT) be coded for invasion of or into (but not through) the visceral peritoneum for an intrahepatic bile duct primary? See Discussion.

EOD Clinical Extension--Prostate: Can you assign code 15 if there is no TURP and no physical exam? See discussion.

[Code 15 = Tumor identified by needle biopsy, e.g. for elevated PSA, (T1c)]

EOD-Clinical Extension--Liver: How do the segments of the liver described by AJCC Manual correspond to the lobes of the liver described by the SEER EOD Manual? See Description.
