Reportability/Histology--Pancreas: Is mucinous cystic neoplasm of pancreas reportable?
Non-invasive mucinous cystic neoplasm (MCN) of the pancreas with low or intermediate grade dysplasia is NOT reportable.
Non-invasive mucinous cystic neoplasm (MCN) of the pancreas with high grade dysplasia is reportable. For neoplasms of the pancreas, the term MCN with high grade dysplasia replaces the term mucinous cystadenocarcinoma, non-invasive.
Laterality--Head and Neck: Were the topography codes C090 and C091 intentionally left off of the Sites for Which Laterality Codes Must Be Recorded table in the 2018 SEER Manual? The codes were also removed from Table 10 in the 2018 Solid Tumor Rules for Head and Neck but appear under coding instructions 1b. and 6b. in the manual.
Thank you for bringing this to our attention. C090 and C091 were intentionally removed from the list of sites for which laterality must be coded. They should have also been removed from coding instructions 1b and 6b. We will make that correction in the next version of the manual.
Reason for No Cancer-Directed Surgery: Could you explain why this field would be coded to 1 [Cancer-directed surgery was not recommended] or 2 [Contraindicated due to other conditions] for a case that presents with distant metastasis at diagnosis?
For cases diagnosed 1998-2002:
Code the Reason for No Cancer-Directed Surgery field to 1 [Cancer-directed surgery was not recommended] for patients who present with either a primary site or histology for which surgery is not a standard treatment. Also use code 1 for those patients who present with distant disease for a primary site that is typically treated surgically. Patients with distant metastasis typically do not have surgery performed as part of first course of treatment.
Code 2 [Contraindicated due to other conditions] is used when surgery would normally be recommended for the site (given the current stage of the tumor) but other medical conditions pose too much of a risk for the patient to undergo surgery.
EOD Fields--All Sites: Is EOD information limited to what is available exactly two months from the day of diagnosis?
For cases diagnosed 1998-2003:
EOD should include all information available within four months of diagnosis in the absence of disease progression or through completion of surgery(ies) in first course of treatment, whichever is longer.
Mets known to have developed after EOD was established should be excluded.
Grade, Differentiation: Is grade always coded to 4 for a diagnosis of Ewing's sarcoma?
Do not code the ICD-O-3 grade for Ewing sarcoma unless documented in the record.
In the TNM system, grade is required to place Ewing sarcoma into a stage group. For TNM staging purposes, Ewing sarcoma is classified as G4. Do not apply TNM rules to ICD-O coding.
Reportability/Histology--Pituitary Gland: How are Rathke cleft cyst and Rathke pouch tumor distinguished and are they both reportable?
Rathke cleft cyst is not reportable. Cysts are not neoplastic. However, Rathke pouch tumor (C751, 9350/1) is a reportable neoplasm for cases diagnosed 2004 and later. The Rathke pouch is coded to the pituitary gland. Benign and borderline pituitary tumors have been reportable since 2004.
Primary site--Heme & Lymphoid Neoplasms: Should the primary site be coded to C421 [bone marrow] or C770-C779 [lymph nodes] for an adult T-cell leukemia/lymphoma [9827/3] that presented with a positive bone marrow biopsy and involvement of lymph nodes and the lung?
Code the primary site to the involved lymph nodes [C770-C779]. Per Rule PH 8, it indicates you are to code the primary site to the site of origin when lymph node(s) or lymph node region(s), tissue(s) or organs are involved. Note 2 further states that the bone marrow may or may not be involved. If the bone marrow is involved, code this information in the CS Extension field.
Per the Abstractor Notes section in the Heme DB, this is a systemic disease with widespread lymph node involvement as well as involvement of the peripheral blood. In addition, systemic involvement of extranodal sites (including lung) are often involved.

Multiple Primaries--Urinary: How many primaries should be coded for an 8/9/07 invasive transitional cell carcinoma of right ureter; 7/9/08 non-invasive urothelial carcinoma of bladder; 11/18/08 non-invasive urothelial carcinoma of left ureter; 6/20/09 invasive urothelial carcinoma of left ureter?
One primary. This is a good example of how the field effect occurs in the urinary system. From 2007 to 2008, Rule M8 says bladder and ureter tumors are not new primaries and would be documented as recurrences. Because other urinary sites are involved by 11/08 and by 06/09, do not make second primary of left ureter (Rule M4 does not apply).
MP/H Rules--Ovary: Rule M7 states bilateral epithelial tumors (8000-8799) are reportable as a single primary. Are bilateral germ cell tumors of the ovary (e.g., dysgerminoma (9060/3)) that occur simultaneously now reported as two primaries?
For cases diagnosed 2007 or later, rule M7 applies to ovarian epithelial tumors with ICD-O-3 histology codes between 8000 and 8799. Rule M7 does not apply to dysgerminoma which is coded to 9060. Go on to the next rule, M8 and abstract as multiple primaries, left and right.
Primary Site--Brain and CNS: Are meninges surrounding cranial nerves cranial meninges [C700] or a part of the specific nerve's sheath? Is the primary site for an optic nerve sheath meningioma coded to optic nerve [C723] or cranial meninges [C700]?
