20020031 Multiple Primaries--Hematopoietic, NOS: When the SEER Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table indicates that a disease is not a new primary, but a pathologist or clinician states that it is a new primary, do we use the physician information or the table?

For cases diagnosed prior to 1/1/2010:If the physician clearly states that this is a new primary, submit it as a new primary. Otherwise, use the Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table.

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.

20021144 EOD-Extension--Colon: What code is used to represent this field for a mid-ascending colon primary that invades through muscularis propria and into subserosal fibroadipose tissue that also presents with a "separate serosal nodule" of carcinoma within cecum that is consistent with a tumor implant (cT3, N0, M1)?

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 85 [Metastasis], because the nodule of carcinoma in the cecum is not contiguous with the mid-ascending primary colon tumor.

20021121 Multiple Primaries (Pre-2007)--Kidney: How many primaries are reportable in a patient treated with a bilateral nephrectomy that revealed multiple tumors within each kidney and the histology in both the left and the right kidney was "renal cell carcinoma, indeterminate type: multiple histologically identical tumors" and the clinical discharge diagnosis was "bilateral renal cell carcinoma, probably surgically cured"? See discussion. The SEER manual states "If only one histologic type is reported and if both sides of a paired site are involved within two months of diagnosis, a determination must be made as to whether the patient has one or two independent primaries." Frequently, the only statement we have is that "bilateral organs are involved." Additional guidelines for determining number of primaries would be helpful.

For tumors diagnosed prior to 2007:

Report this case as two primaries, left and right kidneys. According to our pathologist consultant, "The description sounds like bilateral multiple primaries. Multicentricity in the same kidney occurs in about 4% of all cases, and bilaterality in 0.5 to 3% (Atlas of Tumor Pathology, Tumors of the Kidney, Bladder, and Related Urinary Structures)."

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.

20021004 Histology: What code is used to represent the histology for the abbreviation "ca"? See discussion.

The abbreviation "ca" results in inconsistency when coding histology by a group of coders. Many abbreviation guides list both cancer (8000/3) and carcinoma (8010/3) as definitions for "ca." Page 261 of the SEER Self Instructional Manual, Book 5 lists carcinoma as the definition for "ca."

Example: What histology is used for a case with a clinical diagnosis of "recently diagnosed uterine ca" with metastasis to the pelvic lymph nodes?

For uterine primaries, code the abbreviation "ca" to 8010/3 [carcinoma, NOS].

When coding death certificate only (DCO) cases, if the site is coded to an unknown primary and no specific histology information is available other than the abbreviation "ca," interpret ca as cancer (8000/3) per NAACCR Procedure Guidelines for Registries, Series V; Resolving Death Clearance Issues, page V-15.

20021078 Primary Site: How do you code the primary site when the tumor is identified in a bladder that was reconstructed using a stomach augmentation procedure and the pathology report states, "Bladder/prostate: adenocarcinoma arising within gastric mucosa, with the following features: highly infiltrative through the bladder wall"? Code the Primary Site field to bladder [C67.9]. Code the location of the tumor as the primary site. 2002
20021040 Other Therapy: What code is used to represent treatment with "Epithilone" or "Epothilone"? Code the Other Cancer-Directed Therapy field to 2 [Other experimental cancer-directed therapy (not included elsewhere)], until the exact mechanism of action is determined for this drug. This drug is in phase I clinical trials. It has a similar action to Taxol, but is derived from a different source. 2002
20021113 Surgical Procedure of Other Site--Pancreas: Should an embolization of liver metastasis for a pancreas primary be coded as treatment?

Code "embolization" (or hepatic artery embolization, HAE) to a metastatic site in Surgical procedure of Other Site. Assign code 1 [nonprimary surgical procedure performed].

This procedure was previously coded as other therapy, experimental. Code as surgery as of July 2005.

Primary Site/Surgery of Primary Site--Lymphoma: What codes are used in these fields when both regional lymph nodes and an extra-nodal site are involved with lymphoma and there is not a clear statement from the clinician as to the primary site? See discussion.

In our registry, we code the primary site for such cases to the extra-lymphatic site if there is one extra-nodal site involved with disease and the patient does not have disseminated involvement of multiple extra-nodal sites. Is this correct? Example: A patient with a submandibular lymphoma and involved nodes undergoes a salivary gland excision and a modified radical neck dissection yielding 100 nodes.

For cases diagnosed prior to 1/1/2010:Code the Primary Site to C08.0 [submandibular gland] and use the surgery code schemes that apply to that site (Parotid and Other Unspecified Glands). Physiologically, lymphoma cells in regional lymph nodes do not "back-flow" into the extralymphatic organ to involve it secondarily. As a result, the primary site is usually the extralymphatic organ with regional lymph node involvement. Do not be afraid to code an extralymphatic site as primary when that site and its regional nodes are involved.

If the lymph nodes are not regional to the extra-nodal involved site and the primary site cannot be determined, code the primary site to C77.9 [Lymph node, NOS].

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.

Chemotherapy: Should radiosensitizing chemotherapy agents (i.e., drugs typically coded as treatment for cancer) be coded as treatment when they are given in combination with radiation therapy with the intention of enhancing that treatment? See discussion.

Per our consultant, these drugs are given at a lower dose than that typically given to treat cancer patients.

Do not code radiosensitizers and radioprotectants as cancer-directed therapy. Drugs typically classified as chemotherapy agents would be "ancillary drugs" for the purpose of coding cancer-directed therapy because the drugs are given at a much lower dosage than that typically given to treat cancer patients. Per Book 8, ancillary drugs are not to be coded as cancer-directed therapy. Radiosensitizers and radioprotectants do not work directly on the cancer and are not coded under any of the systemic therapy fields.

20021141 EOD-Extension--Lung: When only minimal information is available, such as scans and needle biopsies, should EOD extension be coded to localized or unknown? See discussion.

The patient was diagnosed with non-small carcinoma of the lung by needle biopsy of the right upper lobe Feb. 2, 2001. History revealed that CT performed prior to needle bx showed 2 right sided lung lesions and right hilar adenopathy. Chest x-ray following needle bx showed irregular opacity within the RML appears unchanged. Soft tissue prominence in the azygos region, possibly related LN enlargement. This is the only information available.

Should we code extension as 30 [localized, NOS]?

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 99 [unknown] if no additional information is available for this case. Because the second lesion in the right lung could be malignant, the extension code might be 77 [separate tumor nodule(s) in different lobe]. With the possibility of a more extensive stage, the status of the hilar lymph nodes is also not clear. The abstracted information is insufficient to stage this case.
