EOD-Extension--Lymphoma/Brain and CNS: How is this field coded for a primary brain lymphoma that is described as multi-focal?
For cases diagnosed 1998-2003: Since brain is the only site involved in this example, assign code 11 [Localized involvement of a single extralymphatic organ or site].
Surgery of Primary Site--Skin: Should this field be coded to 45 [wide excision or reexcision of lesion or minor (local) amputation with margins more than 1 cm, NOS], 46 [with margins between 1 and 2 cm], or 47 [with margins greater than 2 cm] for a skin primary diagnosed in 2003 when margins are stated exactly as 2 cm?
Use code 46 [Wide excision...with margins more than 1 cm and less than 2 cm] when margins are exactly 2 cm.
Per Rule PH30, use the Heme DB, determine the histology when rules PH1-PH29 do not apply. Code diffuse large B-cell lymphoma, germinal cell type to 9680/3 [diffuse large B-cell lymphoma (DLBCL)][9680/3]. Under the Alternate Names section of the Heme DB, these two terms are synonyms that share the same histology code.
SEER*Educate provides training on how to use the Heme Manual and DB.

MP/H Rules/Histology--Gallbladder: What histology is coded for a tumor described as "90% high grade neuroendocrine ca, large cell type; and 10% low grade adenocarcinoma, conventional type"?
For cases diagnosed 2007 or later:
MP/H Rule H17 for Other Sites applies. Code the histology 8140 [adenocarcinoma].
The ICD-O-3 code for large cell neuroendocrine carcinoma is 8013 and the code for adenocarcinoma is 8140.
Histology--Pancreas: How is a "gastrin and somatostatin producing endocrine neoplasm" coded that has lymph node metastasis?
The best code available for this situation is 8153/3 [Gastrinoma, malignant].
Many pancreatic endocrine tumors produce more than one peptide, such as gastrin and somatostatin in this case. ICD-O-3 does not provide a code for pancreatic endocrine tumors which produce more than one peptide. According to the WHO Classification of Tumours of Endocrine Organs, there is a distinct hormonal syndrome associated with gastrin producing tumors, and not with many of the somatostatin producing tumors. Therefore, our pathologist consultant advises us to code to gastrinoma in this case.
Heme & Lymphoid Neoplasms: How is cancer status to be coded when a patient diagnosed with MDS, undergoes treatment, but the MDS subsequently transforms to AML?
If the bone marrow no longer shows evidence of MDS, the cancer status for the MDS is disease-free. When cancer status is coded as disease-free (NED), it means that currently there is no clinical evidence of this disease (MDS).
MP/H Rules/Histology--Thyroid: How many primaries are to be reported and what histology is to be coded for an anaplastic/undifferentiated thyroid carcinoma with sarcomatoid transformation likely arising in association with a papillary thyroid carcinoma? Thyroid contains one tumor: 12.5 cm in greatest dimension...almost completely replaces entire thryroid gland.
For cases diagnosed 2007 or later:
This is a single primary using rule M2; a single tumor is always a single primary.
The histology code for this case is 8260/3 [Papillary carcinoma of thyroid]. Begin with Histology Coding rule H8. Stop at rule H17 and code the histology with the numerically higher ICD-O-3 code.
EOD/Summary Stage--Eye: How is stage coded for a patient with extranodal non-Hodgkin lymphoma involving bilateral choroids (single focus, both sites) and no lymph node involvement? Since the eyes are a paired site, is this two separate extranodal sites? If so, there are no Summary Stage or EOD tumor codes that best fit this scenario.
Assign as Stage IV as recommended by our expert hematological oncologist. This is a rare occurrence and this type of presentation does not fit the definition of intraocular extension. Stage IV is probably the best stage for this type of presentation, since there are two extranodal organs involved, even though they involve a bilateral site.
Primary Site--Pancreas: Should tumors with the histology "islet cell carcinoma" be coded C25.4 [Islet of Langerhans] even though the tumor location is stated to be in head of pancreas?
Assign code C25.4 [Islets of Langerhans...Endocrine pancreas]. Islet cell carcinoma of the pancreas is a tumor of the endocrine pancreas. Although Islet cells are present throughout the pancreas, the best code is C25.4 to distinguish endocrine from exocrine cancers.
Reportability/Terminology, NOS--Hematopoietic, NOS: Is "smoldering" multiple myeloma reportable to SEER?
For cases diagnosed prior to 1/1/2010:Yes, "smoldering" multiple myeloma is reportable to SEER as multiple myeloma [9732/3].
According to our pathologist consultant, "smoldering" multiple myeloma would certainly refer to a diagnosed process. Smoldering means the process is progressing, but perhaps slowly, or even at a slower pace than might be expected.
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.
