Report Question ID Question Discussion Answer Year
20081125 Reportability: Is the following tumor(s) reportable? MRI of thoracic spine shows intramedullary hemangiomas in the bodies of T5 and T6.

Intramedullary hemangiomas in T5 and T6 are not reportable.

These benign tumors originate in the bone, not spinal canal, cord or dura. Benign tumors of the bone are not reportable.

According to WHO, the most common sites of involvement are the vertebral bodies, followed by craniofacial skeleton and long bones.

20081127 MP/H Rules/Histology--Thyroid: How would the histology "micropapillary carcinoma" of the thyroid be coded for cases dx'd 2007 and after?

For cases diagnosed 2007 or later, assign code 8260/3 [Papillary adenocarcinoma] according to rule H14.

For thyroid cancer only, the term micropapillary does not refer to a specific histologic type. It means that the papillary portion of the tumor is minimal or occult, usually less than 1 cm. in diameter.

20081047 Reason no surgery of primary site/First course treatment: If the Reason no Surgery of Primary Site field is coded as 7 (refused), must the other treatment options (radiation, chemo, hormone) also be coded as 7? See Discussion. Coding instruction #5 in the SEER manual states: "Assign code 7 (refused) if the patient refused recommended surgery or made a blanket statement that he/she refused all treatment."

Refused [code 7] means this modality was specifically recommended by the physician and the patient refused. If two treatment alternatives were offered and surgery was refused, code Reason no surgery of primary site 1 [Surgery of the primary site was not performed because it was not part of the planned first-course treatment].

Refusal of surgery does not necessarily mean that all treatment was refused. Coding Surgery of Primary Site as "refused" does not affect the coding of Radiation, Chemotherapy, Hormone Therapy, etc.

20081019 Multiple Primaries--Lymphoma: How many primaries are abstracted for a patient with a 1995 periaortic lymph node biopsy showing lymphocytic lymphoma, diffuse small cleaved probable intermediate grade B cell positive, followed by stomach biopsies on 6/18/05 showing diffuse large B cell lymphoma and on 6/24/05 showing malignant lymphoma, tumor cells positive for [CD20] B cell respectively?

For cases diagnosed prior to 1/1/2010:There are two primaries:

  • Lymphocytic lymphoma, diffuse, intermediate in 1995

  • Diffuse large B-cell lymphoma in June, 2005

    • According to the Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table, 9673 [Malignant lymphoma, lymphocytic, diffuse, intermediate] and 9680 [Malignant lymphoma, large B-Cell, diffuse] are separate primaries. Again, according to the table, 9680 [Malignant lymphoma, large B-Cell, diffuse] and 9591 [Malignant lymphoma, non-Hodgkin, NOS] are the same primary.

    For cases diagnosed 1/1/10 and later, 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.

    		20081138 MP/H Rules/Histology--Lung: What is the correct histology code for a neuroendocrine neoplasm described as a carcinoid and also referred to as oncocytic? See Discussion.

    Left mainstem bronchus mass excised: metaplastic endobronchial mucosa with submucosa containing an infiltrating poorly diff malignant tumor. Origin of tumor is not identified in overlying mucosa. IHC stains will be performed.

    Addendum #1. IHC stains show well diff neuroendocrine neoplasm, favor carcinoid. Recommend sending this to expert in lung neoplastic pathologist.

    Addendum #2. (lung path specialist) oncocytic neuroendocrine neoplasm.

    Is this 8246 or 8290 or something else?

    		 For cases diagnosed 2007 or later, code as 8246 [Neuroendocrine carcinoma, NOS]. According to our pathologist consultant, the neuroendocrine description is more specific than the oncocytic description in this case. 2008
    		20081112 MP/H Rules--Breast: Is a 2008 invasive ductal carcinoma counted as a new primary when it follows a 2005 invasive lobular carcinoma diagnosed in the same breast? See Discussion. The patient has invasive lobular breast carcinoma excised in 2005. She returns in 2008 with a new invasive ductal carcinoma tumor same breast. Following MP/H rules, M10 seems to apply, which states this is still a single primary. Does this mean that this invasive ductal carcinoma is ignored and the patient remains in the registry with only a lobular carcinoma primary?

    For cases diagnosed 2007 or later:

    Rule M10 applies. The 2008 diagnosis is not a new primary.

    The abstract for the 2005 diagnosis should be annotated to include the new information.

    		 2008
    		20081083 Multiple primaries--Lymphoma: Is mediastinal large B-cell lymphoma followed by classical Hodgkin lymphoma reportable as one or two primaries? See Discussion. Diagnosed 06/06/2006 with mediastinal large B-cell lymphoma, 9679/36. On 05/10/2007, another mediastinal lymph node biopsy done and the diagnosis was recurrent malignant lymphoma, classical Hodgkin's. A Hematopatholgy Consultant states, "it appears likely that the preceding mediastinal diffuse large B-cell lymphoma and the current classical Hodgkin's lymphoma are clonally related and represent different manifestations of the same entity. One might also place this in the spectrum of 'mediastinal gray zone lymphoma' described by Dr. Jaffee and colleagues."

    For cases diagnosed prior to 1/1/2010:Report this case as two primaries. Report non-Hodgkin lymphoma followed by Hodgkin lymphoma as separate primaries.

    According to the Table of Single and Subsequent Primaries for Hematologic Malignancies, mediastinal large B-cell lymphoma and Hodgkin disease are "D" - Different disease processes.

    For cases diagnosed 1/1/10 and later, 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.

    MP/H Rules--Breast: Patient has 2 existing primaries, both of left breast and both were pure lobular carcinoma, one was diagnosed in 1994 and the other in 2005. Now a biopsy in 2008 of a supraclavicular lymph node (laterality unknown) and subcutaneous scalp tissue show metastatic DUCTAL carcinoma. Per path report, breast is the primary site. Slides from prior tumors were not reviewed. Should this be made a new primary or assumed to be metastasis from the prior breast tumors? See Discussion.

    A modified radical mastectomy was performed on 10/6/94.

    The 2007 MP/H rules tell us that multiple ductal and lobular tumors of breast are a single primary; however, the rules do not apply to metastatic tumors.

    For cases diagnosed 2007 or later:

    Abstract the 2008 diagnosis as a new primary.

    Since the primary site is unproven but stated to be breast, and since the laterality is unknown, we cannot determine that the 2008 diagnosis is the same as the 2005 or the 1994 diagnosis.

    Revise this case accordingly if more information becomes available.

    		20081003 Reportability--Brain and CNS: For von Hippel Lindau disease with multiple hemagioblastomas, is each hemangioblastoma reportable as a new primary? See Discussion. Diagnosis of von Hippel-Landau disease, multiple brain surgeries between 2002 and 2007 for recurring hemangioblastomas, 9161/1. This disease manifests as multiple (recurring) hemangioblastomas.

    For cases diagnosed 2007-2014:

    If the hemagioblastomas occur in sites with different ICD-O-3 topography codes, they are separate primaries.

    Please note: Rule M4 in the Benign & Borderline Intracranial and CNS Tumors MP/H coding rules on the SEER website has been corrected to read:

    Tumors with ICD-O-3 topography codes that are different at the second (Cxx), third (Cxx) and/or fourth (Cxx) characters are multiple primaries.(http://www.seer.cancer.gov/tools/mphrules/benign_brain.html)

    		20081008 Surgery of Primary Site--Breast: How is this field coded when a re-excision follows a prior mastectomy?

    Code the most extensive surgery in Surgery of Primary Site. This is a cumulative field. Assign the appropriate code including all surgeries of the primary site performed during the first course of treatment.

    The correct code for mastectomy followed by re-excision will depend on the extent of the re-excision. For example, if the re-excision removed muscle, code radical mastectomy.
