Reportability--Stomach: Is a well-differentiated neuroendocrine tumor of the stomach reportable?
Well-differentiated neuroendocrine tumor (NET) of the stomach is reportable. The WHO classification of digestive system tumors uses the term NET G1 (grade 1) as a synonym for carcinoid and well-differentiated NET, 8240/3.
Reportability--Brain and CNS: Is this diagnosis reportable? If this neoplasm originated in the spinal cord, it is reportable, correct?
Specimen is described as a 'spinal cord mass.' The final diagnosis is 'fragments of adipose tissue demonstrating vascular proliferations consistent with angiolipoma. No histologic evidence of malignancy.' The microscopic description says: Sections of the spinal mass reveal bone, cartilage, fibrous tissue and adipose tissue. The adipose tissue demonstrates increased vascularity with thin walled blood vessels seen with islands of delicate fibrous stroma. The histologic findings are compatible with fragments of angiolipoma.
The neoplasm is reportable if it originated in the spinal cord or is intradural (within the spinal dura; spinal nerve roots are intradural). If there is not enough information to determine the exact site of origin, do not report the case.
Histology (Pre-2007): What code should be assigned to acinar adenocarcinoma and ductal adenocarcinoma?
For tumors diagnosed prior to 2007:
Assign code 8255 [Adenocarcinoma with mixed subtypes]. According to histology rule #4 for a single tumor on page 86 of the 2004 SEER manual, use a combination code if one exists.
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.
Primary site/Histology--Peritoneum: What is the correct primary site code for peritoneal mesothelioma in a female? When I use C482, it seems that the fields are all geared towards primary peritoneal carcinoma with FIGO staging, etc.
For mesothelioma, NOS (9050) and epithelioid mesothelioma (9052) of the peritoneum for females, assign C481, C482, or C488 as appropriate based on the site of origin in the medical documentation. The Primary Peritoneal Ca schema is assigned and you will need to complete the SSDIs for FIGO staging, CA-125 PreTx Interpretation, and Residual Tumor Volume Post Cytoreduction.
If the histology is 9051 or 9053 with primary site of C481, C482, or C488 for females, the Retroperitoneum schema is assigned. The only SSDI for this schema is Bone Invasion.
Primary Site: How is this field coded for cholangiocarcinoma involving the intrapancreatic bile duct?
Code the primary site as C24.0 [Extrahepatic bile duct, includes Common bile duct] for a cholagiocarcinoma originating in the common bile duct. A portion of the common bile duct is within the head of the pancreas: The intrapancreatic segment of the common bile duct.
EOD-Extension--Corpus Uteri: How is this field coded for a stage III A endometrial primary with positive pelvic washings, involvement of the omental serosa, and negative lymph nodes?
For cases diagnosed 1998-2003: Code EOD-extension as 85 [Metastasis]. According to our TNM consultant, Omental metastasis is M1, Stage IVB [EOD 85].
Reportability/Grade, Differentiation: Does the term "grade 0" refer to differentiation or does its use as a modifying phrase in the final diagnosis of "grade 0 immature teratoma" impact reportability?
Regarding the term "grade 0" for an immature teratoma, determine whether the pathologist is using that term to describe the primary tumor or its implants. The term can be used to describe both situations.
An immature teratoma (IT) may have grade 0 (benign) implants. Grade 0 implants may affect the prognosis and treatment, but the primary tumor (IT) would still be malignant and therefore reportable. If grade 0 pertains to the primary tumor (as opposed to implants) it is benign, and therefore not reportable.
SEER Manual/Reportability--Vulva: Is vulvar intraepithelial neoplasia (VIN II) alone reportable? An example is a final diagnosis from a pathology report that states only 'VIN II' with no additional details/wording.
Report VIN II. The 2024 SEER Manual lists this as a separate diagnosis in the Reportability section under Malignant Histologies 1.a.x.
Primary site--Anus/Anal Canal: What site do you code squamous cell carcinoma of the anal verge?
Assign C211 for anal verge. Anal verge is defined as the lower (distal) end of the anal canal, junction between the skin of the anal canal and the perianal skin, http://www.seer.cancer.gov/manuals/2015/AppendixC/rectosigmoid/coding_guidelines.pdf
Surgery of Primary Site/Surgery Codes, NOS--Pancreas: What exactly is an extended pancreatoduodenectomy? Must the entire pancreas be resected in order to use code 70? What minimal requirements must be met to use code 70? How should a Whipple with cholecystectomy, partial omentectomy, common hepatic excision, portal vein resection, and lymphadenectomy be coded?
According to our research, a pancreaticoduodenectomy (PD) includes an en bloc resection of the pancreatic head, the common bile duct, the gallbladder, the duodenum, the upper jejunum, the distal portion of the stomach and the adjacent lymph nodes. The extended PD procedure includes extended lymphadenectomy, extended organ resection, and extended vascular resection and reconstruction.
Code 70 could be assigned without the entire pancreas being resected.
A Whipple procedure removes the head of the pancreas, duodenum, stomach and gallbladder and part the common bile duct. The portal vein resection is probably part of the common bile duct excision. If the omentectomy was performed for treatment of this primary, record it in "Surgical Procedure of Other Site." Record the lymphadenectomy in the lymph node data items.
