When the choice is between ovary, fallopian tube, or primary peritoneal, any indication of fallopian tube involvement indicates the primary tumor is a tubal primary. Fallopian tube primary carcinomas can be confirmed by reviewing the fallopian tube sections as described on the pathology report to document the presence of either serous tubal intraepithelial carcinoma (STIC) and/or tubal mucosal invasive serous carcinoma.

If there is no information about the fallopian tubes, refer to the histology and look at the treatment plans for the patient. If all else fails, you may have to assign C579 as a last resort. Use text fields to document the details.

For additional information, see the CAP GYN protocol, Table 1: Criteria for assignment of primary site in tubo-ovarian serous carcinomas.

Solid pseudopapillary neoplasm of the pancreas is reportable for cases diagnosed in 2014 and later. Report solid pseudopapillary neoplasm of the pancreas (8452/3) as the guidance in SINQ 20140058 is still in effect.

The 4th and 5th editions of the WHO Classification of Tumors of the digestive system define solid pseudopapillary neoplasm of the pancreas as a low-grade malignant pancreatic tumor.

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 Code 9684/3 [malignant lymphoma, diffuse large B-cell, immunoblastic NOS] is obsolete for cases diagnosed 2010 and later per the Heme DB.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

SEER*Educate provides training on how to use the Heme Manual and DB.

Code histology for PanIN-III to 8148/2 [Glandular intraepithelial neoplasia, grade III]. The Multiple Primary and Histology Coding Rules Manual is the correct source for coding histology.

For cases diagnosed 2007 or later, the following steps are used to determine the histology code:

Open the Multiple Primary and Histology Coding Rules manual. For a pancreas primary, use the Other Sites Histo rules to determine the histology code because pancreas does not have site specific rules.

Go to the SINGLE TUMOR: IN SITU ONLY module, start at rule H1. Code 8148/2 [Glandular intraepithelial neoplasia, grade III]. There is only one histologic type identified.

In the next version of the MP/H rules, the H22 rule "Code 8148/2 (Glandular intraepithelial neoplasia grade III) for in situ glandular in sites such as the (PAIN III)" will be included under H2 as well. Currently the rule is only in the MULTIPLE TUMORS ABSTRACTED AS A SINGLE PRIMARY module and should also be include under the SINGLE TUMOR: IN SITU only module.

Code the histology to 8575/3.

The instruction for coding duct and another non-duct histology not listed in Table 3 was inadverantly left out of the rules. The default is to code to the histology with the numerically higher ICD-O-3 code which is 8575/3.

AIN II is reportable for 2021. Squamous intraepithelial neoplasia, grade II is listed in ICD-O-3.2 as 8077/2 making it reportable for cases diagnosed in 2021. AIN is a type of squamous intraepithelial neoplasia.

The wording in Appendix E of the 2021 SEER manual (must be unequivocally stated as grade III to be reportable) was left over from earlier versions and is not correct for 2021 diagnoses. Follow the guidance in SINQ 20210048.

For cases diagnosed 1/1/03 and later:

1. Code Surgery of Primary Site to 30 and Scope of Regional Lymph Node Surgery to 3.

2. Code Surgery of Primary Site to 41.

3. Code Surgery of Primary Site to 40 and Scope of Regional Lymph Node Surgery to 3.

4. Code Surgery of Primary Site to 40.

5. Code Surgical Procedure of Other Site to 4.

The SEER rules changed in 1998 regarding what constitutes First Course of Cancer-Directed Therapy.

For cases diagnosed on or after 1/1/98: The First Course of Cancer-Directed Therapy fields will all be coded to 0 [None] for these types of cases. The documented disease progression would stop the timeframe for inclusion of any treatment to be part of first course of therapy.

For tumors diagnosed prior to 2007:

Assign code 8771 [Epithelioid cell melanoma]. Code the cell type when specified.

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.

For cases diagnosed prior to 1/1/2010:Code the Grade, Differentiation field to 5 [T-cell] in the 6th digit of the ICD-O-3 morphology field when the terms "pre-T cell" or "T-precursor" are used. However, this is not an official change to ICD-O-3.

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.
