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

Idiopathic and autoimmune types of thrombocytopenia are not reportable. Thrombocytopenia and thrombocythemia are not synonyms. Cytopenia and cythemia have different definitions. See Appendix F: Non-Reportable List for Hematopoietic Diseases.

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.

For cases diagnosed 1998-2003: If 7mm is the measurement of the infiltrating duct portion of this cancer, assign extension code 13 [Invasive and in situ components present, size of invasive component stated and coded in Tumor Size].

If 7mm is the size of the whole malignancy and the size of the invasive portion cannot be determined, assign extension code 14 [Invasive and in situ components present, size of entire tumor coded in Tumor Size (size of invasive component not stated) and in situ described as minimal (less than 25%)]. "Focal areas of in situ carcinoma" qualifies as minimal.

For reportability, interpret "suspicious for but not diagnostic of" as NOT diagnostic of cancer.

The phrase "suspicious for the possibility of early invasive adenocarcinoma" may indicate that the case is in situ. If no further information is available, this is not reportable.

The site of the cancer diagnosis does not change the interpretation.

For cases diagnosed 1998-2003:

No. Never code the aggregate size in the Size of Primary Tumor field when the pieces removed come from TWO OR MORE tumors. If there is a clinical statement regarding the size of two or more tumors, code this field to the size of the largest tumor.

The aggregate size can only be used to code the Size of Primary Tumor field when the PATHOLOGIST estimates the size of the tumor from the pieces of ONE tumor removed by the surgeon.

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

Code the primary site to C421 [bone marrow]. Our hematopoietic specialty physicians state that involvement of peripheral blood is equivalent to bone marrow involvement because the marrow produces blood. In the absence of any other involvement, per Module 7 (Coding primary sites for lymphomas) Rule PH26, it states to code the primary site to bone marrow when the only involvement is bone marrow.

For cases diagnosed prior to 1/1/2010:

Code the Grade, Differentiation field to 1 [Grade 1] for both of these cases because there is no mention of T-cell, B-cell, null cell, or NK cell involvement. Both cases have a pathologic description of well differentiated, not the descriptors "high grade," "low grade," or "intermediate grade" which must be ignored when coding grade for lymphomas.

For lymphomas, you cannot code the descriptions "high grade," "low grade," and "intermediate grade" in the Grade, Differentiation field because these terms refer to categories in the Working Formulation and not to histologic grade. However, you can code terms such as "well differentiated", "moderately differentiated" and "poorly differentiated" for lymphoma histologies.

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.

For cases diagnosed 1998-2003:

Use the following criteria to determine whether or not certain clinical findings qualify as "B" symptoms.

1. Fevers. Unexplained fever with temperature above 38 degrees C.

2. Night sweats. Drenching sweats that require change of bedclothes.

3. Weight loss. Unexplained weight loss of more than 10% of the usual body weight in the 6 months prior to diagnosis.

Pruritus alone does not qualify for B classification, nor does alcohol intolerance, fatigue, or a short, febrile illness associated with suspected infections.

The clinical description in the example above does not meet the criteria for B symptoms. Generally, the symptoms in the B category have to occur over an extended period of 7 to 30 days. In this case the fever is explained by "typical cold symptoms" and in addition, three days of fever is not a long enough period.

1st primary, 8/23/12: Follicular lymphoma, grade 1 2nd primary, 1/6/14: Diffuse Large B Cell Lymphoma

Apply the multiple primary rules twice for this case. The 2012 diagnosis is follicular lymphoma. There are two histologies in 2014: diffuse large b cell lymphoma and follicle center cell lymphoma diagnosed at the same time in the same location. This is one primary per rule M4.

Then compare the 2012 diagnosis to the 2014 diagnosis.

Per the Hematopoietic Database, follicular lymphoma (all types) transforms to DLBCL. Per Rule M10, the DLBCL would be a second primary.

Assign code 22 for LUL wedge resection followed by a lingular-sparing LUL lobectomy and mediastinal lymph node dissection.  Code the lymph node surgery in Scope of Regional Lymph Node Surgery. We obtained input from an expert who agrees with this code. He states a lingula-sparing lobectomy is best coded as a segmentectomy because it is the same as an apical trisegmentectomy.
