20031048 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. N/A N/A 2003
20000495 EOD Fields--All Sites: Is EOD information limited to what is available exactly two months from the day of diagnosis?

For cases diagnosed 1998-2003:

EOD should include all information available within four months of diagnosis in the absence of disease progression or through completion of surgery(ies) in first course of treatment, whichever is longer.

Mets known to have developed after EOD was established should be excluded.

20031203 Surgery of Primary Site--Skin: Should this field be coded to 45 [wide excision or reexcision of lesion or minor (local) amputation with margins more than 1 cm, NOS], 46 [with margins between 1 and 2 cm], or 47 [with margins greater than 2 cm] for a skin primary diagnosed in 2003 when margins are stated exactly as 2 cm? Use code 46 [Wide excision...with margins more than 1 cm and less than 2 cm] when margins are exactly 2 cm. Skin Surgery of Primary Site 2003
20110108 Primary site--Heme & Lymphoid Neoplasms: What is the primary site for a bone marrow biopsy positive for systemic mastocytosis that also involves the spleen and lymph nodes with associated leukocytosis, mild anemia and thrombocytopenia?

Updated May 2026

Per the Heme DB, code the primary site to C421 [bone marrow] because that is the only site listed under the Primary Site section of the Heme DB.

Under the Abstractor Notes section in the Heme DB, it indicates that the bone marrow is always involved, and the white and red pulp of the spleen may be involved with systemic mastocytosis. This is how this patient presented; therefore, the bone marrow is the primary site. The spleen is secondarily involved because the spleen cleanses the blood and the neoplastic cells have infiltrated the red and white pulp of the spleen. The same is true for the lymph nodes. Although the lymph nodes are rarely involved, they may be involved when the patient has systemic mastocytosis.

20021209 EOD-Extension/EOD-Lymph Nodes--Rectosigmoid: How do you code these fields for a scan-based clinically staged T3 N1 rectosigmoid primary in a patient who received chemotherapy and radiation prior to a resection that demonstrated invasion only into the muscularis and no positive lymph nodes?

For cases diagnosed 1998-2003:

Use the best information available, in this case, the clinical staging, to code EOD. Code the EOD-Extension field to 40 [Invasion through muscularis propria or muscularis, NOS] and the EOD Lymph Node field to 3 [Regional lymph node(s) NOS] because the case had a clinical stage of T3 N1. EOD is coded using the most extensive clinical or pathologic stage.

20031002 Histology (Pre-2007)--Cervix: Is 8384/3 [adenocarcinoma, endocervical type] a specific histology type that must be stated or does it apply to any adenocarcinoma arising in the endocervical? Should the ICD-O-3 histology code of 8384/3 [Adenocarcinoma, endocervical type] be used for final diagnoses of "adenocarcinoma of the endocervix" or "adenocarcinoma of the cervix"?

For tumors diagnosed prior to 2007:

Histology code 8384 is for adenocarcinoma of endocervical type. This specific type (endocervical) must be part of the diagnosis in order to assign code 8384. This histology code is not to be used for Adenocarcinoma, NOS of the endocervix or cervix.

Adenocarcinoma of endocervical type can be diagnosed in other tissues and if so it will be stated as endocervical type. Adenoca of the endocervix would be coded to plain Adenoca.

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-Extension--Pancreas: Should these terms be ignored when coding extension to 10 or 30, or do they indicate involvement for non-surgically treated pancreas primaries?

1) Stricture of the common bile duct

2) Common bile duct is narrowed

3) Common bile duct is obstructed

4) Common bile duct dilation

5) Malignant stricture of the common bile duct

6) Ampullary or common bile duct stricture with a negative biopsy or brush.

For cases diagnosed 1998-2003:

Ignore these terms when coding extension to 10 or 30. These terms do not verify involvement by pancreatic cancer of the organs mentioned. Other non-malignant circumstances could cause these conditions.

20021059 Surgery of Primary Site--Soft Tissue: What code is used to represent this field when an excisional biopsy of a soft tissue sarcoma is followed two weeks later with a wide excision (re-excision)? For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 26 [partial resection]. According to the CoC, "Excision" in the surgery codes refers to the lesion and "partial resection" refers to the organ. The biopsy is a local excision (code 25). The wide resection is code 26, presuming that more than just the remaining lesion was removed. Sarcoma Surgery of Primary Site 2002

Recurrence (Pre-2007)--Colon: When there is no statement of recurrence on the abstract, is a colon tumor at the anastomosis site a recurrence of the previous colon cancer or a new primary?

For tumors diagnosed prior to 2007:

If the cancer at the anastamosis site is more than two months after the previous colon cancer, abstract as a separate primary.

If the cancer at the anastamosis site is within two months of the original diagnosis and the histologies are the same, do not abstract as a separate primary.

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.

20110084 Histology--Heme & Lymphoid Neoplasms: Is histology coded to 9684/3 [malignant lymphoma, diffuse large B-cell, immunoblastic NOS] for a biopsy that reveals "diffuse large B-cell lymphoma, immunoblastic variant"?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Code histology to 9680/3 [diffuse large B-cell lymphoma]. Code 9684/3 [malignant lymphoma, diffuse large B-cell, immunoblastic NOS] is obsolete for cases diagnosed 2010 and later per the Heme DB.

Under the Definitions section in the Heme DB, it states that this is a lymphoma with diffuse proliferation of large neoplastic B lymphoid cells with nuclear size exceeding macrophage nuclei, more than twice size of normal lymphocytes. Normal architecture of node or extranodal tissue replaced in diffuse pattern. Morphologic variants: centroblastic, immunoblastic, plasmablastic, T-cell/histiocyte-rich, anaplastic.
