Behavior--Breast: Is a breast biopsy diagnosis of "ductal carcinoma in situ with focal and very early stromal invasion" an invasive tumor with a behavior code 3?

Code the behavior to /3 [malignant, invasive].

"Stromal invasion" means the cancer is invasive. "Stroma" is the supporting connective tissue around and between ducts. It is outside the duct basement membrane. If the tumor cells extend into the stroma, the proper behavior designation for the tumor is invasive.

20110008 MP/H Rules/Histology--Vulva: How is histology coded for VIN III with focal invasion? See Discussion. Per SINQ 20000442, the histology for CIN III with microinvasion is coded to 8077 [squamous intraepithelial neoplasia, grade III] per the matrix system rules, with a behavior code of /3 [malignant]. Coding the histology to 8077/3 per the matrix principle causes IF25_3 and MorphICDO3_P1 edits to fail. Flagging the first error resolves any reporting issue. How is the MorphICDO3_P1 edit resolved? Assign 8076/3 [squamous cell carcinoma, microinvasive] for VIN III with focal invasion. This applies to all terminologies listed under 8077/2. The SINQ question from 2000 will be retired. 2011
20110101 Primary site--Heme & Lymphoid Neoplasms: Is the primary site coded to C778 or C779 for a diffuse large B cell lymphoma with abdominal lymph node, neck lymph node, and spleen involvement?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Use Rule PH21 to code the primary site to C778 [lymph nodes of multiple regions]. The spleen is not listed under the Primary Site(s) section in the Heme DB for diffuse large B-cell lymphoma. Per Rule PH21 code the primary site to multiple lymph node regions, NOS (C778) when multiple lymph node regions, as defined by ICD-O-3, are involved and it is not possible to identify the lymph node region where the lymphoma originated. The spleen is a primary site for only a few lymphomas (noted in the Heme DB). Because the spleen filters blood, it is often reactive (splenomegaly) or frankly involved with the lymphoma. That reaction or involvement, however, does not affect the primary site coding. Only the involved nodes are used in coding primary site.

Reportability--Heme & Lymphoid Neoplasms: Is "common variable immunodeficiency" which is also known as acquired hypogammaglobulinemia reportable?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Common variable immunodeficiency (acquired hypogammaglobulinemia) is not a reportable condition.

Common variable immunodeficiency represents a group of approximately 150 primary immunodeficiencies that have a common set of symptoms but different underlying causes, both benign and malignant.

The case is not reportable unless this immunodeficiency diagnosis is accompanied by a diagnosis of a cancer or a reportable hematopoietic or lymphoid neoplasm.

See Appendix F: Non-Reportable List for Hematopoietic Diseases.

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]?

Code the primary site to cranial meninges [C700].

MP/H/Histology--Lung: What is the histology code for "heterologous biphasic sarcomatoid carcinoma of the lung with prominent rhabdomyoblastic and adenoca differentiation"?

The expert pathologist recommends coding histology to 8980/3 [Carcinosarcoma] for this combination histology.

Expert consultation: The designation "carcinosarcoma" is given when the pathology shows differentiation in both the sarcomatous (rhabdomyoblastic) and carcinomatous (adenoca) elements. This is emphasized in the path for this case with the term "biphasic." The term "heterologous" mean that the sarcomatous component is of a type not normal to lung. Rhabdomyoblastic means skeletal muscle differentiation. Because skeletal muscle is not normally found in lung it is heterologous. If it were smooth muscle, it would be homologous because smooth muscle is found in lung (as a part of the bronchi).

20110096 Behavior--Lung: How is behavior to be coded for a diagnosis of adenocarcinoma of a lung tumor that is further classified per the CAP protocol as, "non-mucinous bronchiolo-alveolar carcinoma (adenocarcinoma in situ)" while the pathologist also classifies the tumor as pT1b, pN0? See Discussion. Is the following case coded with an invasive or in situ behavior when a RUL lobectomy specimen reveals adenocarcinoma and the Histologic Type per the CAP protocol layout is non-mucinous bronchiolo-alveolar carcinoma (adenocarcinoma in situ)? The stage per the pathologist is pT1b, pN0. Per the COMMENT section in the pathology report, "The terminology adenocarcinoma in situ is based on a recent publication in the Journal of Thoracic Oncology (Volume 6, #2, February 2011). Based on this criterion, the behavior represents adenocarcinoma in situ with no evident invasive component." Code the behavior as in situ. The pathologist has the final say on the behavior of the tumor. This pathologist is indicating that in his opinion based on a recent publication, this tumor is in situ. 2011

Reportability--Heme & Lymphoid Neoplasms: Are the terms EBV positive B-cell lymphoproliferative disorder with or without the term "of the elderly" and iatrogenic EBV positive lymphoproliferative disorder reportable? See Discussion.

The only reportable term listed is "EBV positive B-cell lymphoproliferative disorder of the elderly." Are the following cases reportable?

  • Does the diagnosis of EBV positive B-cell lymphoproliferative disorder specifically have to include the expression "of the elderly" to be reportable? Is there an age range associated with the term "of the elderly"?
  • Is "iatrogenic EBV positive lymphoproliferative disorder" reportable?
  • Is a diagnosis of "EBV positive B-cell lymphoproliferative disorder" reportable when there is no further classification of the LPD as lymphoma?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

  1. EBV positive B-cell lymphoproliferative disorder is reportable. Code EBV positive lymphoproliferative disorder as DLBCL [9680/3], the term "of the elderly" does not have to be part of the diagnosis.
  • The term "iatrogenic" simply means that there is no known cause for the disease. Iatrogenic EBV positive lymphoproliferative disorder is reportable.
  • EBV positive B-cell lymphoproliferative disorder is a synonym for DLBCL [9680/3]. You do not need to have the lymphoma (DLBCL) diagnosis.

20110007 MP/H Rules/Multiple primaries--Bladder: How many primaries are to be abstracted and how are the histologies coded when a bladder resection demonstrates tumor with invasive small cell neuroendocrine carcinoma [8041/3], high grade papillary urothelial carcinoma in situ [8130/2], adenocarcinoma in situ [8140/2], and multifocal flat urothelial carcinoma in situ? See Discussion.

Are the areas of in situ tumor to be ignored or would MP/H Rule M9 apply?

Ignore the in situ histologies. This is a single primary. Code the histology to invasive small cell neuroendocrine carcinoma [8041/3]. 2011
20110108 Primary site--Heme & Lymphoid Neoplasms: What is the primary site for a bone marrow biopsy positive for systemic mastocytosis that also involves the spleen and lymph nodes with associated leukocytosis, mild anemia and thrombocytopenia?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Per Rule PH30, one is to use the to determine the primary site and histology when rules PH1-PH29 do apply. Code the primary site to C421 [bone marrow] because that is the only site listed under the Primary Site section of the Heme DB.

Under the Abstractor Notes section in the Heme DB, it indicates that the bone marrow is always involved, and the white and red pulp of the spleen may be involved with systemic mastocytosis. This is how this patient presented; therefore, the bone marrow is the primary site. The spleen is secondarily involved because the spleen cleanses the blood and the neoplastic cells have infiltrated the red and white pulp of the spleen. The same is true for the lymph nodes. Although the lymph nodes are rarely involved, they may be involved when the patient has systemic mastocytosis.
