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.

20000476 Surgery of Primary Site--Ovary: What code is used to represent this field when a patient has a history of a previous organ removal and has additional surgery/organ removal for a present cancer (e.g., History of a 1984 hysterectomy and in 2003 has ovarian primary treated with BSO)? For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 52 [Bilateral salpingo-oophorectomy WITH hysterectomy]. 2000
20000512 EOD-Extension/EOD-Lymph Nodes--Kaposi Sarcoma: What code is used to represent this field for a Kaposi sarcoma with no skin lesions but positive lymph node and bone marrow biopsies?

Code the EOD-Extension field to 13 [Visceral (e.g., pulmonary, gastrointestinal tract, spleen, other)], because of the positive bone marrow. Code the EOD-Lymph Nodes field to 3 [Both clinically enlarged palpable lymph nodes (adenopathy) and pathologically positive lymph nodes], for the pathologically positive node.

Note: Potential revision of the extension scheme will be referred to SEER Medical Advisory Group (SMAG).

20100104 Grade--Heme & Lymphoid Neoplasms: Is the phrase "aberrant T-cell expression" enough to code the grade field to T-cell when the final diagnosis on the pathology report is "AML with aberrant T-cell antigen expression"? Yes. Code grade to 5 [T-cell]. The T cell receptor, or TCR, is a molecule found on the surface of T lymphocytes (or T cells). 2010
20020009 EOD-Extension--Lymphoma: What code is used to represent this field for a lymphoma that involves the spleen and lymph nodes above the diaphragm (e.g., involvement of only the spleen below the diaphragm and cervical lymph nodes above the diaphragm)?

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 32 [30 + involvement of the spleen; III S]. The spleen is counted twice (once as the spleen and a second time as a lymph node region below the diaphragm). As a result, the EOD-Extension field is coded to reflect involvement of lymph node regions on both sides of the diaphragm plus involvement of the spleen. See Note 1 on the EOD scheme that states "Any lymphatic structure is to be coded the same as a lymph node region."

20031062 Primary Site--Melanoma: How would this field be coded for a pleural effusion consistent with metastatic melanoma and "no skin lesions?" Code primary site as C44.9 [Skin, NOS]. ICD-O-3 does not list a suggested site code for 8720/3 because melanoma can arise in other parts of the body. However, C44.9 [Skin, NOS] is the default when the primary cannot be found. 2003
20020066 Chemotherapy: How is treatment with Iressa (Gefitinib) coded?

Code treatment with Iressa as chemotherapy.

Iressa is an epidermal growth factor inhibitor. While it doesn't kill cells directly, it damages the cell reproduction process. We classify it as a chemotherapy agent.

 2002
20021138 Grade, Differentiation--All Sites: What code is used to represent this field when a pathology report describes a tumor as a low grade neoplasm consistent with a specific histologic type (e.g., Low grade neoplasm consistent with carcinoid)? Code the Grade, Differentiation field to 2 [Low grade]. 2002
20000478 Multiple Primaries (Pre-2007)--Breast: When a breast cancer is treated with less than a total mastectomy and more than 2 months later a tumor of the same histology is diagnosed in the same breast with no statement of "recurrence," is this a new primary?

For tumors diagnosed prior to 2007:

Count as 2 primaries when a subsequent malignant breast tumor is diagnosed more than 2 months later unless stated to be a recurrence. For cases diagnosed after 1/1/94, an in situ followed by an invasive breast cancer is counted as two primaries even if stated to be a recurrence.

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.

Behavior--Breast: Is behavior for encapsulated papillary carcinoma (EPC) of the breast coded as noninvasive or invasive?

The pathologist has the final say on behavior. Code behavior based on the pathologist's final diagnosis. See Rule F in ICD-O-3.

According the WHO Classification of Breast Tumors, encapsulated papillary carcinoma of the breast is in situ, /2. Encapsulated papillary carcinoma with invasion is assigned /3. WHO describes "frank invasive carcinoma" for this histology as "neoplastic epithelial elements infiltrate beyond the fibrous capsule of encapsulated papillary carcinomas." WHO cautions that true infiltration should be "differentiated from entrapment of neoplastic epithelial cells in the fibrous capsule and from epithelial displacement into the biopsy site, which is frequently encountered following needle-core procedures of papillary lesions."
