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.
Primary Site/Histology--Lymphoma: How are these fields coded when the final diagnosis per the pathology report is, "Soft tissue and skeletal muscle, left thigh--Large B cell lymphoma with polyclonal and mature t-cells, involving the soft tissue"?
For cases diagnosed prior to 1/1/2010:Site: C492 [Soft tissue thigh]
Histology: 9680/36 [T-cell rich large B-cell lymphoma]
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.
CS Mets at Dx/CS Mets Eval--Colon: Would the metastasis field be coded to 00 [No; none] and the evaluation field be coded to 1 [No path exam of metastatic tissue performed.] when the source of information is from the operative findings for the following 6 different cases? 1) Liver normal; 2) No evidence of metastatic disease; mesentery normal, 3) Small ascites; no liver metastasis, mass adherent to duodenum without obvious invasion, 4) No mets or local invasion, 5) No evidence of carcinomatosis, peritoneal studding or malignant effusion and 6) Tumor adherent to lateral sidewall (path negative); no evidence of metastatic implants.
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.
The CS Mets Eval code refers to the method used to evaluate the site farthest from the primary site. The correct code may not be the highest eval code. For example 1 above, if the liver is the site farthest from the colon primary that was evaluated for distant mets, code the CS Mets Eval code to the method used to evaluate liver. Code surgical evaluation as 1.
Assuming this is all of the information about possible distant metastatic sites for the examples above, code CS Mets at DX as 00, and CS Mets Eval as 1 for each.
Please note: imaging of farther sites should also be included when CS Mets at DX is coded. For example, if there was also a negative chest X-ray, the CS Mets at DX field would be 00 but the CS Mets Eval field would be 0 because the CXR documents that there are no mets beyond the immediate area of the tumor.
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.
Update to Current Manual/2018 EOD Manual/EOD Primary Tumor--Bladder: According to the American Joint Commission on Cancer (AJCC), a transurethral resection of the bladder (TURB) cannot make a distinction between involvement of the superficial muscle-inner half (Stage T2a) and the deep muscle-outer half (Stage T2b). Is this same criteria applied to Extent of Disease (EOD)?
EOD follows AJCC criteria in this situation and we have confirmed with AJCC that Stage T2a (superficial muscle) and Stage T2b (deep muscle) cannot be assigned when only a TURB is done.
For EOD Primary Tumor, Bladder, codes 200, 250, 300, 350, can only be used when
Cystectomy is performed
Muscularis propria is involved, AND
Pathology report states superficial muscle (200, 250) or deep muscle (300, 350) is involved
If a TURB is done and there is mention of the muscularis propria invasion (superficial muscle or deep muscle), use EOD codes 370 or 400. If a TURB is done and the pathology report states superficial or deep muscle, ignore and coded as “invasion of muscularis propria, NOS” (EOD codes 370 or 400).
Instructions and code descriptions for EOD Primary Tumor have been updated to indicate this. These updated instructions and code descriptions will be available when SEER*RSA is updated for 2024, Version 3.1 (Sept/Oct 2023). These updates are included here for reference and can be applied for cases diagnosed 2018+.
Residence at dx: After living elsewhere (Florida) and traveling around the country in an RV with his spouse, is a patient a resident of this area for either primary if he was diagnosed with his first primary less than a month after arriving in the area and a second primary more than a year after parking his RV here?
Use the patient's usual residence to determine residency. If the usual residence is not known or the information is not available, use the residence the patient specifies at the time of diagnosis. The SEER rules for determining "usual residence" match the rules used by the US Census Bureau.
Reportability/Histology--Pancreas: Is mucinous cystic neoplasm of pancreas reportable?
Non-invasive mucinous cystic neoplasm (MCN) of the pancreas with low or intermediate grade dysplasia is NOT reportable.
Non-invasive mucinous cystic neoplasm (MCN) of the pancreas with high grade dysplasia is reportable. For neoplasms of the pancreas, the term MCN with high grade dysplasia replaces the term mucinous cystadenocarcinoma, non-invasive.
CS Eval--All Sites: If any of the CS fields (TS/Extension, LN, or Mets) are based on the TNM and there is no text documenting the basis for the evaluation, are the evaluation fields coded to 0 instead of 1?
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.
Assign code 0 [No surgical resection done...based on physical exam...or other non-invasive clinical evidence] to the corresponding eval fields when CS Extension, Lymph Nodes or Mets at Diagnosis are coded based only on the TNM and no further information is available.
