Code the Grade, Differentiation field to 1 [grade I] using the information from the BR score.

For cases diagnosed 1998-2003: Grade or differentiation information from breast pathology reports is used in the following priority order:

1. Terminology (well, moderately, poorly)

2. Histologic grade (grade I, grade II)

3. BR scores

4. BR grade

5. Nuclear grade

On the hierarchical list for coding breast grade, the first two priorities do not apply to this case, but the third (Bloom-Richardson scores) does. Add the BR information (2+1+1) for a total score of 4, which translates to BR low grade (code 1). The statement of "II/III" may be a typo that should state I/III.

For tumors diagnosed prior to 2007:

Code the Histology field to 8570/3 [Adenocarcinoma with squamous metaplasia]. Our pathology consultant agrees that squamous metaplasia is synonymous with squamous differentiation.

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.

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 14 [invasive and in situ components present, size of entire tumor coded in Tumor Size AND in situ described as minimal (less than 25%)]. The pathologist did not use a code as defined by SEER. For cases described as "less than or equal to 25%", choose the lower of the two EOD code choices.

Yes, those modalities should be counted as part of first course of cancer-directed treatment if the patient continues with the planned first course. For example, if patient has the originally planned type of surgery, radiation, or drug protocol, then code the given treatment as first course.

Caution: It is not a change in the treatment plan if the drugs are changed but the action of the drugs remains the same. This is still first course. However, if the treatment is changed from a chemotherapy drug to a hormonal drug following the discovery of the mets, do not code the hormonal therapy as first course.

For cases diagnosed 2004-2006:

Endometrioid adenocarcinoma with squamous differentiation is coded 8570 [Adenocarcinoma with squamous metaplasia].

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.

For cases diagnosed 1998-2003:

Yes, if the cystic mass is pathologically confirmed to be malignant, code the EOD-Size of Primary Tumor field based on the size of the mass in the absence of a more precise tumor size description. For the examples in the discussion section, code the EOD-Size of Primary Tumor field to: 1) 100 [10 cm]. 2) 090 [9 cm].

As a point of interest, the size of tumor for ovarian and brain primaries is not used in either analysis or as a prognostic indicator for survival. Therefore, spending time separating the cystic and solid portions of the tumor is unnecessary.

For cases diagnosed prior to 1/1/2010:

Code as two primaries with each arising in lymph nodes [C77._]. The histology for the first primary is 9699/3 [marginal zone B cell lymphoma]. The histology for the second primary is 9680/3 [large B cell lymphoma].

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 1/1/2003 and after, code:

1. Surgery of Primary Site field to 60 [Radical cystectomy (male only)] because the cystoprostatectomy was the most extensive (definitive) surgery performed to the primary site.

2. Surgical Procedure of Other Site to 2 [Non-primary surgical procedure to other regional sites] based on the TURP.

For cases diagnosed 1998-2003:

Code the EOD-Lymph Nodes field to 9 [Unknown], based on the information provided.

The physician's statement of an N category from a TNM may be used to determine lymph node involvement in the absence of other information. However, you cannot assume nodal involvement based on the incomplete staging information of "Stage IV" for a base of tongue primary. For this primary site, extension into the hypopharynx from this primary is equivalent to T4/Stage IV. Therefore you cannot assume the clinician's assessment of the case as Stage IV represents his assessment of lymph node involvement.

For cases diagnosed 1998-2003:

Code the EOD-Size of Primary Tumor field to 999 [Not stated] for the example given above. However, if the opacity was described as a "mass" or as "suspicious for cancer," the size could be coded to 040 [4 cm].
