Primary site/Histology--Heme & Lymphoid Neoplasms: How are these field coded when a biopsy of a substernal mass and the pericardium show T-cell lymphoblastic lymphoma/leukemia, the CT scan showed mediastinal and hilar adenopathy and no bone marrow biopsy was done?
Code the histology to 9837/3 [T lymphoblastic leukemia/lymphoma].
To determine the primary site for leukemia/lymphoma histologies, first go to Module 4. Per Rule PH8, code the primary site to the site of origin when lymph nodes, tissue or organs are involved. To determine a more specific histology, go to Module 7, rules for coding primary site for lymphomas. Per Rule PH20, code the lymph node region when multiple lymph node chains within the same region are involved. Mediastinal and hilar lymph nodes are intrathoracic lymph nodes. The substernal mass is also intrathoracic and is presumed to be a lymph node mass which involved the pericardium. For this case, code the primary site to C771 [Intrathoracic lymph nodes].

Extension/CS Extension--Prostate: Do the prostate guidelines used for EOD still apply to cases diagnosed 2004 forward?
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.For cases diagnosed 2004 and forward, refer to the Collaborative Staging manual.
The 2004 CS guidelines have been agreed upon by all standard setters and have been reviewed by the COC/AJCC urologists.
Note: Do not use the SEER EOD guidelines with Collaborative Staging.
EOD-Size of Primary Tumor--Colon: When an adenocarcinoma is stated to be arising in an adenoma and the "tumor size" stated in the final pathologic diagnosis is the same size as the mass described in the gross description, should we assume that the entire polyp has been totally/near totally replaced by tumor and code the tumor size stated in the final path diagnosis?
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary Tumor field as stated by the pathologist in the final pathologic diagnosis. If the size of the tumor is the same as the size of the polyp, assume the polyp was completely replaced by tumor.
Reportability/Histology--Gallbladder: Is intracholecystic papillary-tubular neoplasm (ICPN) with extensive high grade dysplasia of the gallbladder reportable?
Report intracholecystic papillary neoplasm (ICPN) with high-grade dysplasia (8503/2) of the gallbladder.
MP/H Rules--Lung: In reference to lung, SINQ 20071028 states "'nodule' is not an equivalent term for tumor, mass, lesion, or neoplasm." However, slide 5 for the MPH lung section of "Beyond the Basics" states "we use the words 'mass, nodule and lesion' interchangeably." Which is it?
For cases diagnosed 2007 or later:
For the purpose of applying the Lung MP/H rules, the word "Nodule" can be used interchageably with "Tumor," "Mass," "Lesion" and "Neoplasm." HOWEVER, this does NOT apply to casefinding or staging.
This revision will be added to the next version of the MP/H rules. Sinq question 20071028 will be revised.
Date of Diagnosis: How do you code this field when the pathologic confirmation is delayed for 2 months because the clinician decides to "watch and see what happens" to a CT identified mass thought to be either a "metastasis from a previously diagnosed malignancy or a new primary"?
Code the Date of Diagnosis field to the date of the scan. This is the earliest date that a recognized medical practitioner said the patient had cancer. The diagnosis on the CT scan was a malignancy. The only question was whether the mass on the scan was metastatic or a primary.
Reportability--Hematopoietic, NOS: Is "evolving" multiple myeloma reportable to SEER?
For cases diagnosed prior to 1/1/2010:No, it is not SEER reportable. The diagnosis of "evolving" multiple myeloma could represent a plasmacytoma, plasma cell dyscrasia or another lymphoproliferative disorder. Some of these histologies are SEER reportable, but some are not. Additional information would be needed to determine reportability. If you are unable to obtain more information, the case is non-reportable.
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.
Primary site--Breast: how is subsite coded for a breast cancer when it is described as central portion between 1-3:00 or central portion at 12:00?
See the SEER coding guidelines for breast, https://seer.cancer.gov/manuals/2018/AppendixC/Coding_Guidelines_Breast_2018.pdf Generally, codes C502 - C505 are preferred over C501. C501 would be preferred over C508. Apply these general guidelines when there is no other way to determine the subsite using the available medical documentation.
Table 1, Primary Site codes, in the breast solid tumor rules also provide helpful information for coding site.
EOD-Regional Lymph Nodes--Breast: Are subpectoral nodes the same as interpectoral nodes and, therefore, regional for breast primaries?
Subpectoral lymph nodes are regional nodes for breast primaries. Subpectoral is the term generally used to describe the placement of a prosthesis during reconstruction (under/behind the pectoralis major muscle). That is the same location for interpectoral, or Rotter's, nodes.
Reportability/Histology--Gallbladder: Is Intracholecystic papillary neoplasm (ICPN) with low-grade intraepithelial neoplasia reportable? The primary site is gallbladder.
Intracholecystic papillary neoplasm (ICPN) with low-grade intraepithelial neoplasia is not reportable. The WHO assigns a behavior of 0 to these neoplasms.
