EOD/Surgery of Primary Site--Melanoma: If a melanoma primary site is other than skin, vulva, penis, or scrotum should these fields be coded using melanoma schemes? See discussion.
Should a melanoma of the cervix be coded using the melanoma or the cervix schemes for these fields?
For cases diagnosed 1998-2003: Use the EOD and surgery code schemes for cervix uteri. The EOD scheme for melanoma excludes melanoma of the cervix uteri. The surgery code scheme for skin excludes cervix uteri.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Breast: How many primaries are to be abstracted and how is the histology field(s) coded when a nipple biopsy demonstrates Paget disease and a separate biopsy in the same breast demonstrates inflammatory breast carcinoma? See Discussion.
Should Paget disease be coded as the histology because it has a higher histology code than inflammatory carcinoma?
For tumors diagnosed prior to 2007:
Abstract the inflammatory carcinoma as one primary and the Paget disease as a separate primary. The first three digits of the histology codes for these histologies are different (8530 and 8540). Therefore, these are separate primaries.
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.
EOD-Lymph Nodes--Testis: In coding lymph node involvement for a testicular primary, should we use code 5 (Size not stated) when there is not a pathologic size of the lymph node provided? See discussion.
Should Note 1 in the testis EOD be changed to "Metastases in lymph nodes are now measured by the size of the lymph node as stated in pathology report"? The SEER EOD-88, 3rd Edition, states that "when size of regional lymph nodes is required, code from the pathology report."
For cases diagnosed 1998-2003:
For testis cases only, "metastasis in lymph nodes" is measured by the size of the lymph node or the lymph node mass. It is acceptable to code the size of this metastasis from a CT scan or other imaging when a pathology specimen is not available for testicular primaries.
Histology (Pre-2007)--Corpus Uteri: How should this field be coded when the D&C which shows "adenocarcinoma with mucinous and papillary features" and the TAH demonstrates only "endometroid carcinoma"? See Discussion.
Should Histology be coded to 8380 [endometroid adenocarcinoma] because it is the most representative sample or to 8323 [mixed cell adenocarcinoma], per the Complex Morphology Coding Guidelines? The instructions in the Guidelines seem to imply that it is most important to represent combination histologies first, with majority (most representative sample) of tumor having a lower priority.
For tumors diagnosed prior to 2007:
Code Histology based on the pathology report from the most representative tissue. For the example above, code Histology to 8380 [Endometroid adenocarcinoma] based on the TAH/BSO pathology report.
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.
Histology (Pre-2007): Do the terms "keratinizing" or "non-keratinizing" have to be present in the final diagnosis to use codes 8071 through 8073? See discussion.
Should "squamous cell carcinoma, small cell variant" be coded to 8073 even though the final diagnoses does not include the phrase "non-keratinizing?"
For tumors diagnosed prior to 2007:
It is acceptable to assign code 8073/3 for squamous cell carcinoma, small cell, NOS. Code squamous cell carcinoma, large cell, NOS to 8072/3. Code to non-keratinizing unless the pathology report specifies keratinizing.
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.
Race, ethnicity/Spanish surname or origin: If birthplace is Brazil or Portugal, patient's last name is on the Spanish Surname list, and there is no text to further clarify ethnicity, what is the correct Spanish Ethnicity code: 0 or 7? See Discussion.
See also SINQ 20081075.
Assign code 7 [Spanish surname only] when the last name is on the Spanish Surname list. This includes cases for which the birthplace is Brazil, Portugal or the Philippines and there is no text to further clarify ethnicity.
The instruction to use code 0 [Non-Spanish/Non-Hispanic] in the SEER manual on page 51 (#2) applies when the only information available is the birthplace or a statement of "Portuguese," "Brazilian" or "Filipino."
CS Reg LN Pos/Exam: Are lymph nodes coded as positive or negative when the pathology report for a lymph node dissection performed after radiation and chemo reveals that the nodes are negative but they demonstrated previous involvement by cancer? See Discussion.
Scenario: The patient was treated with radiation and chemotherapy prior to resection for esophageal cancer. The pathology report stated, "1/3 nodes c/w treated previous ca."
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.Record lymph nodes that are pathologically confirmed as positive in Regional Nodes Positive. Evidence of previous involvement by cancer is not recorded in this data item.
In the above scenario, the lymph nodes are negative according to pathology.
Clinically positive lymph nodes are coded in CS Lymph Nodes.
MP/H Rules--Lung: Per rule M8, tumors of the same site (left lung), same histology (NSCC), greater than 3 yrs apart are separate primaries.
However, there was a recurrence to mediastinal LNs after 2 years. Would that make a difference as to whether the 2008 left lung carcinoma is reportable as a new primary or not? See Discussion.
Scenario: NSCC 2004 LLL with positive hilar/mediastinal LNs treated with LLL lobectomy, chemo and rad. 2006 per CT/PET recurrence in mediastinal LNs treated with chemoradiation. 2008 left lung nodule positive for NSCC stated by MD to be recurrence from 2004 (2008 path not compared to 2004 path).
For cases diagnosed 2007 or later:
The 2008 lung carcinoma is a separate primary according to rule M8. The 2006 diagnosis is metastases to the lymph nodes. Do not apply the MP/H rules to metastases.
Ambiguous Terminology/Date of Conclusive Terminology: If there is an unknown date of diagnosis, should the Ambiguous Terminology field always be coded to 9 and the Date of Conclusive Terminology be coded to 99999999? See Discussion.
Scenario: Mammogram is suspicious for carcinoma, unknown date in 2007. A biopsy prior to admission to reporting facility is positive for carcinoma. Patient seen at reporting facility in June 2007 for treatment.
The purpose of the data item "Ambiguous Terminology" is to flag cases entered into the registry based on a diagnosis with ambiguous terminology. Because the case above was entered into the registry based on conclusive terminology, code Ambiguous Terminology to 0 [Conclusive term] and code Date of Conclusive Terminology to 88888888 [not applicable].
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when biopsies of the left and right tonsils show diffuse large B-cell lymphoma and there is no other evidence of involvement? See Discussion.
Scans are negative for lymphadenopathy and the bone marrow biopsy was benign. Radiation Oncology staged this as localized bilateral tonsil primary lymphoma.
This case should be accessioned as a single primary, diffuse large B-cell lymphoma [9680/3] of bilateral tonsils. Per Rule M2, a single histology is a single primary. Note 1 for Rule M2 states bilateral involvement of lymph nodes and/or organs is still a single primary.
