Reportability--Hematopoietic, NOS: Is "evolving" multiple myeloma reportable to SEER?
For cases diagnosed prior to 1/1/2010:No, it is not SEER reportable. The diagnosis of "evolving" multiple myeloma could represent a plasmacytoma, plasma cell dyscrasia or another lymphoproliferative disorder. Some of these histologies are SEER reportable, but some are not. Additional information would be needed to determine reportability. If you are unable to obtain more information, the case is non-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.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported for a patient with a 6/5/12 RUL biopsy that is positive for MALT lymphoma and a 6/7/12 cervical lymph node biopsy that is positive for follicular lymphoma?
Per Rule M15, abstract two primaries for this case. According to M15, use the Heme DB Multiple Primaries Calculator to determine the number of primaries for all cases that do not meet the criteria of M1-M14. The result is two primaries, MALT lymphoma [9699/3] and follicular cell lymphoma [9690/3].
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.
Histology--Breast: Does "cancerization" mean invasive for a breast tumor described as "DCIS with lobular cancerization"?
No, cancerization is not a synonym for invasive. Cells of DCIS can extend not only along the duct but also into the terminal lobules. This extension is referred to as lobular cancerization.
CS Lymph Node Examined--Lung: How is this field coded when a mediastinoscopy and lobectomy are performed and the pathology report indicates multiple lymph node fragments were removed as biopsy specimens and the lobectomy specimen revealed 3 interlobar lymph nodes?
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.
Code the CS Lymph Node Examined field to 98 [number unknown] because the biopsy information is not clear and as a result you do not know how many lymph nodes were examined.
Histology (Pre-2007)--Lung: Should "moderately differentiated adenocarcinoma of scar type, intermixed with bronchiolo-alveolar carcinoma" be coded to 8250 [bronchiolo-alveolar adenocarcinoma, NOS] or 8255 [adenocarcinoma of mixed subtypes]?
For tumors diagnosed prior to 2007:
Code Histology to 8255 [Adenocarcinoma with mixed subtypes]. This is a single tumor containing both a scar carcinoma and a bronchiolo-alveolar carcinoma--use 8255. The synonym for 8255 is adenocarcinoma combined with other types of carcinoma (not just subtypes).
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Primary site--Heme & Lymphoid Neoplasms: What the primary site for a diagnosis of Langerhans cell histiocytosis with multifocal multisystem involvement of the skin, chest, CNS and thyroid, but no evidence of involvement on a bone scan?
Langerhans Cell Histiocytosis (LCH) includes three major groups:
Unifocal: Slowly progressing disease, involves one organ.
Multifocal unisystem: Involves several organs in one system.
Multifocal multisystem: Involves several organs in two or more systems.
When the disease is both multifocal and multisystem, code the primary site to unknown [C809] because there is no way to identify the origin of the neoplasm in this situation.

Multiple Primaries (Pre-2007)/Recurrence--Cervix: How many primaries should be abstracted if a patient had a diagnosis in 1998 of adenocarcinoma in situ of the cervix treated with a total hysterectomy and a July 2004 vaginal mass biopsy with a diagnosis of invasive adenocarcinoma that is consistent with an endocervical primary?
For tumors diagnosed prior to 2007:
Abstract the July 2004 diagnosis as a new endocervical primary. Abstract an invasive cancer in the same site more than two months after an in situ cancer as a new primary. Residual cervical tissue is present following a hysterectomy.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
First course treatment--Heme & Lymphoid Neoplasms: Why isn't darbepoietin coded as treatment for hematopoietic diseases?
Darbepoietin is a synthetic form of erythropoietin. It stimulates erythropoiesis (increases red blood cell levels) and is used to treat anemia, commonly associated with chronic renal failure and cancer chemotherapy.
Darbepoietin is a support medication; it does not treat cancer. It is used to treat anemia caused by cancer directed chemotherapy treatments. It is not indicated for patients with myeloid cancers; cancers that originate in the bone marrow like leukemia.
Darbopoietin is an ancillary drug and is not coded as treatment.
SEER Summary Stage 2000--Melanoma: Can Clark's level classification still used to Summary Stage melanoma? It was previously used by AJCC TNM, but was not included in the 7th edition. I see it is still listed in the CAP protocols for melanoma.
Clark's level can be used to assign in situ, localized or regional summary stage.
If there is a discrepancy between the Clarkâs level and the pathologic description of extent, use the higher Summary Stage code.
Histology (Pre-2007)--Sarcoma: How is "acral myxoinflammatory fibroblastic sarcoma" coded?
For tumors diagnosed prior to 2007:
The ICD-O-3 histology code is 8811/3 [Fibromyxosarcoma] according to the WHO Classification of Tumours of Soft Tissue and Bone. WHO defines myxoinflammatory fibroblastic sarcoma (MIFS) as "a unique low grade sarcoma with myxoid stroma, inflammatory infiltrate and virocyte-like cells that predominantly involves the hands and feet."
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
