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

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--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/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/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/Heme & Lymphoid Neoplasms--Myeloid Sarcoma: How is Extent of Disease (EOD) Primary Tumor coded for a myeloid sarcoma with multifocal skin involvement? See Discussion.

EOD 2018/EOD Regional Nodes--Thyroid: How is Extent of Disease (EOD) Regional Nodes coded for thyroid primary with cervical lymph nodes containing psammomatous calcifications (psammoma bodies) but negative for metastatic tumor cells? See Discussion.

EOD 2018/EOD Regional Nodes--Oropharynx: Is code 550 missing “< equal to 6 cm” in the data item EOD Regional Nodes for Oropharynx HPV-Associated, Version 9? Otherwise, bilateral or contralateral lymph nodes with extranodal extension (ENE) that are >6 cm could fit into 550 OR 650.

EOD 2018/EOD Regional Nodes--Melanoma: Can central cancer registries code Extent of Disease (EOD) Regional Nodes as 000 based on Breslow’s depth and/or Clark’s Level (per EOD and/or Summary Stage) from a melanoma pathology only report with a localized tumor and no information on regional lymph nodes or mets. See Discussion.
