CS Lymph Nodes--Lung: If the lymph nodes listed in codes 10 and 20 were contralateral or bilateral, and the only description was "mass", "adenopathy", or "enlargement" on mediastinoscopy or x-ray, is this field coded to 60? See Discussion.
(CS Manual page 407) Note 2: If at mediastinoscopy/x-ray, the description is "mass", "adenopathy", or "enlargement" of any lymph nodes named as regional in codes 10 and 20, assume that at least regional lymph nodes were involved.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Yes. The named nodes listed in codes 10 or 20 should be coded 60 if the "mass", "adenopathy", or "enlargement" on mediastinscopy or x-ray is described as bilateral or contralateral.
Reportability--Melanoma: Is the following reportable? See Discussion.
PATH: Skin, Lt back exc bx: compound nevus with severe cytoarchitectural atypia and regression. Comment: due to overlap of morphology between MM and nevi with severe atypia, and since there's evidence of regression, consideration for re-excision may be considered if clinically indicated.
The final diagnosis, compound nevus with severe atypia, is not reportable. This diagnosis is not listed in ICD-O-3.
Reportability--Hematopoietic, NOS: Is a "Myelodysplasia, refractory macrocytic anemia with multilineage dysplasia" reportable?
For cases diagnosed prior to 1/1/2010:Yes, myelodysplasia, refractory macrocytic anemia with multilineage dysplasia is reportable. This is a type of refractory anemia. Refractory anemia is reportable.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
CS Tumor Size--Lung/Breast: Explain why the SEER instructions differ from the CS Manual regarding priority order of sources to code tumor size? See Discussion.
Regarding the 2004 SEER Manual, Appendix C, Site Specific Coding Modules, Lung and Breast. The priority of sources for coding tumor size is Pathology, Operative Report, PE, imaging for breast and pathology, operative, endoscopic, and imaging for lung. This differs from the CS Manual instructions.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.For cases diagnosed in 2007 and forward, follow the instructions in the 2007 SEER manual and the CS manual.
CS Extension--Head & Neck (Larynx): If a patient with cancer of the larynx is described as experiencing hoarseness, is that sufficient information to code "vocal cord fixation" or does that phrase need to be used?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Do not code vocal cord fixation when the only information available is "hoarseness." Vocal cord fixation must be documented on endoscopy. Hoarseness is a common presenting symptom of laryngeal malignancy.
Histology--Leukemia: How is a "plasmacytoid dendritic cell leukemia/lymphoma" coded when it is discovered on a bone marrow biopsy for a patient who presented with multiple enlarged lymph nodes and the discharge diagnosis was Type 2 plasmacytoid dendritic cell leukemia?
For cases diagnosed prior to 1/1/2010:
The best code currently available for this entity is 9727/3 [precursor cell lymphoblastic leukemia].
The WHO classification refers to this as "Blastic NK-cell lymphoma." The 2005 WHO-EORTC classification for cutaneous lymphomas states that blastic NK-cell lymphoma may be derived from a plasmacytoid dendritic cell precursor. They suggest more appropriate terms for this condition may be "CD4+/CD56+ hematodermic neoplasm," and "early plasmacytoid dendritic cell leukemia/lymphoma." According to WHO, this is a rare form of lymphoma.

For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Grade, Differentiation: How is grade coded for cases using the FNCLCC (Federation Nationale des Centres de Lutte Contre Ie Cancer) system? See Discussion.
Is FNCLCC a recognized system in the United States? Tongue was the primary site for the case we saw that used FNCLCC.
Do not code the data item Grade based on the FNCLCC grade. You may record the FNCLCC grade in a text field.
Multiplicity Counter: Are in situ tumors diagnosed more than 60 days after invasive tumors of the same site and histology included in the Multiplicity Counter?
If an in situ tumor following an invasive tumor is a single primary according to the multiple primary rules for that particular site, include the in situ and the invasive tumors in the multiplicity counter.
MP/H Rules/Histology--Brain and CNS: Is it generally correct that the code for PNET [9473/3] should be used to code tumors arising in the brain and spinal cord, and the code for pPNET [9364/3] should be used to code tumors arising in the bone and soft tissue? See Discussion.
The terms and definitions for "Brain" in the 2007 MP/H rules distinguish between pPNET and PNET. Is it correct even when the diagnostic terminology alone would lead to other coding, such as "PNET" used to diagnose a soft tissue mass in the chest and "neuroectodermal tumor" used to diagnose a brain mass?
Should additional rules be added to both "Brain" and "Other Sites" to enforce this distinction?
For cases diagnosed 2007 or later:
Yes. Assign code 9473/3 for tumors arising in the brain and spinal cord and assign code 9364/3 for tumors arising in the bone and soft tissue.
Clarification and reinforcement of this distinction will be added to the "Other sites" terms and definitions with the first revision to the MP/H rules.
