EOD-Extension--Stomach: How is this field coded for a stomach primary that has metastases to "Sister Mary Joseph's Nodes?"
For cases diagnosed 1998-2003: For a stomach primary, code extension to 70 [Abdominal wall]. Sister Mary Joseph's nodule is a cutaneous umbilical metastasis most commonly from an intra-abdominal primary.
This rare form of cutaneous umbilical metastasis results from spread of tumor within the falciform ligament. The umbilicus is part of the abdominal wall.
Multiple Primaries (Pre-2007)/Recurrence--Breast: Has SEER established a priority of medical opinions to determine the number of primaries or a time parameter establishing recurrence? When a pathologist and a physician refer to the subsequent reappearence in the same breast as both "recurrence" and "new primary"? See Description.
Example 1. Patient was diagnosed with right breast cancer in 1999 and underwent lumpectomy followed by radiation therapy. In 2001, patient was again found to have right breast cancer and was admitted for mastectomy. The surgeon stated that this was recurrence. The patient's primary care physician stated the patient had a new primary. Is there a priority order if the multiple physicians involved in a patient's care do not agree on the diagnosis?
Example 2. Patient was diagnosed in 1998 with left breast cancer. In 2000, the patient again was diagnosed with left breast cancer. There was no mention of recurrence so case was accessioned as a second primary. In 2003, patient was again admitted for an unrelated disease. In the H&P, the physician stated that the patient had recurrent breast cancer in 2000. Do we remove the second primary from our file based on this statement three years later?
Example 3. Patient was diagnosed with Paget's disease with intraductal carcinoma, left breast, in 1997. In August 2002, patient underwent left mastectomy for DCIS, left breast. In November 2002, patient's oncologist stated that patient had been on Evista for 5 years and had recurrent cancer despite Evista. Do we accession this as one or two primaries?
For tumors diagnosed prior to 2007:
Use the best information available. In general, information from the time closest to the event in question is more accurate than later information. The opinion of the pathologist tends to be the most valuable. Beyond that, SEER has not established a hierarchy of physician opinions.
Be aware that a physician's use of the term "recurrence" does not always mean that the second tumor originated from cells from the first tumor.
Examples 1, 2 & 3. Follow SEER rules for determining multiple primaries. In each case, the diagnoses are more than two months apart. Abstract as two 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.
Primary Site/EOD-Size of Primary Tumor--Lung: If the only lung mass described in CXR is a "hilar mass," is the primary site coded to C34.9 [Lung, NOS] or C34.0 [Main Bronchus; incl. Carina]? Also, can the size of the hilar mass be used to code the size of tumor field?
Because the only description available is "hilar mass," code primary site as C34.0.
For cases diagnosed 1998-2003: Use size of mass for EOD-Size of Primary Tumor.
Diagnostic Confirmation--Hematopoietic, NOS: Is a multiple myeloma diagnosed by an FNA of the lumbar spine (or any other non-bone marrow location) a diagnostic confirmation 1 or 2? See Description.
Does the rule on page 111 of the SEER Program Coding Manual, 3rd Edition, for code 1 apply to myelomas (in the same way it applies to leukemias)?
Assign code 1 [Positive histology] for aspiration of bone marrow. This rule is not limited to leukemias.
EOD-Extension--Thyroid: Is this field coded as involvement of the thyroid capsule if the thyroidectomy path specimen reveals papillary thyroid ca "tumor present within capsular blood vessels?"
For cases diagnosed 1998-2003: Tumor present within the blood vessels of the thyroid capsule is localized (extension code 30). The tumor has not penetrated the capsule itself if it is contained within the blood vessels.
Keep in mind that tumor size determines the extent of disease for thyroid extension codes 10, 20, 30 and 40.
EOD-Size of Primary Tumor: How is tumor size coded when there is a clinical tumor size, the excisional biopsy pathology report has a tumor size and the resection specimen has residual tumor, but there is no tumor size provided in the pathology report?
For cases diagnosed 1998-2003: Code the EOD-Size of Primary Tumor from the excisional biopsy. If there is some indication that a large amount of tumor was removed at the time of the resection, code the clinical size instead. When both an excisional biopsy and a resection show tumor, code the largest size of tumor reported.
Histology (Pre-2007): Is 8524 [lobular mixed with other carcinoma] or 8490 [signet ring cell carcinoma] used to represent a diagnosis of "infiltrating lobular with signet ring features?"
For tumors diagnosed prior to January 1, 2004:
According to our pathologist consultant, for this specific case, code to 8490 [Signet ring cell carcinoma].
Our pathologist states: "Signet ring cell carcinoma is most often a variant of lobular carcinoma (as it appears to be in this case - it is less frequently a variant of ductal), and I think it's appropriate to code it as such. Coding to lobular would also be ok, though that would lose the special feature of the signet ring cells. I would rather not code to 8524, since it is not really a mix of lobular and something else."
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)--Lung: Should the histology "Polymorphic Adenocarcinoma" be coded to 8022/33 [Polymorphic Carcinoma] or 8140/33 [Adenocarcinoma, NOS]?
For tumors diagnosed prior to 2007:
The histology code for pleomorphic adenocarcinoma of the lung is 8140 [Adenocarcinoma, NOS]. According to our pathologist consultant, "Given lung as primary site I prefer 8140. This loses the pleomorphic modifier, but going to 8022 loses the adeno- designation which is more important. Pathologists occasionally use pleomorphic carcinoma for lung tumors which otherwise dont show any adeno or squamous differentiation, for which 8022 would be appropriate, but in this case we do have the adeno designation."
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.
First Course Treatment--Thyroid: Is hormone replacement following total thyroidectomy coded as first course treatment for all thyroid cases?
Code Hormone therapy as 01 [Hormone therapy administered as first course therapy] when thyroid replacement therapy is part of the first course of treatment for follicular or papillary thyroid cancer following thyroidectomy.
Thyroid hormone replacement therapy has a treatment effect on differentiated (follicular and papillary) carcinomas of the thyroid. This treatment effect is not seen for most medullary and undifferentiated thyroid cancers.
