First Course Treatment--Lymphoma: Should the use of proton pump inhibitors be coded as treatment for lymphoma primaries in patients with H Pylori?
No, do not code proton pump inhibitors as treatment. These are used for gastric acid suppression. Proton pump inhibitors are used to treat symptoms, not the lymphoma itself.
Histology (Pre-2007)/Flag--Pancreas: How is histology coded given that 8046 [non-small cell carcinoma] of the pancreas is not on the SEER Site/Type validation listing?
For tumors diagnosed prior to 2007:
Assign 8046 [non-small cell carcinoma] for "non-small cell carcinoma" of the pancreas. If necessary, override any site/type edits.
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.
Reportability--Brain and CNS: Is benign neural tissue compatible with a glioneuronal hamartoma of the cerebellopontine angle reportable?
No. A glioneuronal hamartoma is not neoplastic and not reportable. See page 2 of the 2004 SEER Program Coding and Staging manual for the list of reportable brain/CNS tumors. There is no ICD-O-3 code for hamartoma.
CS Site Specific Factor--Breast: If there are two ER/PR tests, one positive and one negative, which result should be coded in the SSF fields 1 and 2? See Discussion.
SINQ #20021074 states that for cases up to 2003, if there are differences in ER/PR results, to code the positive findings over the negative findings. Does this hold true for coding SSF1 & SSF2 for breast?
Scenario: 10/19 Breast bx: ER + PR -; No date/specimen: ER/PR -; 12/3 Partial Mast: ER/PR +
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
For cases diagnosed prior to January 1, 2007, according to the CS Steering Committee, record the pathologist's interpretation of the assay value for the most representative tumor specimen. This may require conversation with the pathologist when specimen size is not specified.
CS Tumor Size--Breast: Should this field be coded to 999 [Unknown] or 008 [0.8 cm tumor] when the tumor size is not provided on a stereomammotomy biopsy for an in situ malignancy and a subsequent excision demonstrates 0.8 cm tumor of residual in situ disease?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Code CS tumor size 008 [0.8cm]. A mammotomy specimen is very small, so for this case, the residual tumor size is quite accurate. Size is not a critical data element for in situ breast cancer.
Marital Status: Is marital status coded to 2 [married] if the patient is legally married to a same-sex spouse (e.g., patient has a Canadian spouse and in Canada, same-sex marriages are legal)?
Code marital status for same-sex persons based on the legal status. For the case example above, assign code 2 [married].
Ambiguous Terminology--Breast: Is a stereotactic biopsy that is "focally suspicious for DCIS" reportable if it is followed by a negative excisional biopsy? See Discussion.
Per the 2004 SEER manual page 4, 1.a, the case is reportable based on the ambiguous term "suspicious" for DCIS.
Per the 2004 SEER manual page 4, 1.c, use these terms when screening diagnoses on pathology reports, operative reports, scans, mammograms, and other diagnostic testing other than tumor markers.
Note: If the ambiguous diagnosis is proven to be not reportable by biopsy, cytology, or physician's statement, do not accession the case.
Do not accession this case. The needle localization excisional biopsy was performed to further evaluate the suspicious finding found on stereotactic biopsy. The suspicious diagnosis was proven to be false.
Reportability/Behavior--Hematopoietic, NOS: Is a "myelodysplastic/myeloproliferative disease, unclassifiable" coded to 9975 with a behavior code of 3 as indicated in the WHO blue book on "Tumours of Haematopoietic and Lymphoid Tissues" or is it not abstracted because it has a behavior code of 1 which means the case is not reportable?
For cases diagnosed prior to 1/1/2010:Code MDS/MPD U to 9975/3 [Myelodysplastic/myeloproliferative disease, unclassifiable]. Change the behavior code to /3 according to ICD-O-3 Rule F. The case is reportable.
The WHO book is more recent and gives a specific code for this new hybrid category of the WHO/REAL classification.
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.
CS Tumor Size/CS Site Specific Factor--Breast: Should the tumor size be coded to 1.5 cm or 2.5 cm and SSF6 coded to 020 or 030 respectively for a tumor with invasive and in situ components described as being a 2.5 cm tumor with a "greater than" 1.5 cm invasive portion? See Discussion.
Should tumor size be coded to 1.5 cm and SSF6 coded to 020 [Invasive and in situ components present, size of invasive component stated and coded in CS Tumor Size] or should the tumor size be 2.5 cm with SSF6 coded to 030 [Invasive and in situ components present, size of entire tumor coded in CS Tumor Size because size of invasive component not stated and in situ described as minimal (less than 25%)]?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Code CS tumor size 992 [stated as greater than 1 cm] and SSF6 code 020.
The September 2006 revision to the CS Tumor Size table now lists the 992-995 range codes as "greater than ___ cm."
It is better to code the invasive size than the entire size of the tumor. In the TNM mapping, this would more accurately portray the tumor as T1c rather than T2.
Histology--Leukemia: How is a "plasmacytoid dendritic cell leukemia/lymphoma" coded when it is discovered on a bone marrow biopsy for a patient who presented with multiple enlarged lymph nodes and the discharge diagnosis was Type 2 plasmacytoid dendritic cell leukemia?
For cases diagnosed prior to 1/1/2010:
The best code currently available for this entity is 9727/3 [precursor cell lymphoblastic leukemia].
The WHO classification refers to this as "Blastic NK-cell lymphoma." The 2005 WHO-EORTC classification for cutaneous lymphomas states that blastic NK-cell lymphoma may be derived from a plasmacytoid dendritic cell precursor. They suggest more appropriate terms for this condition may be "CD4+/CD56+ hematodermic neoplasm," and "early plasmacytoid dendritic cell leukemia/lymphoma." According to WHO, this is a rare form of 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.
