20041038 Reportability--Bladder: Is "low grade papillary urothelial neoplasm with no evidence of invasion" reportable to SEER? "Neoplasm" means "new growth," not malignancy. A low grade papillary urothelial NEOPLASM with no evidence of invasion [8130/1] is not reportable to SEER. However, a low grade papillary urothelial CARCINOMA with no evidence of invasion [8130/2] is reportable.
20051026 Surgery of Primary Site--Skin: What surgery code is used to reflect the amputation of a finger for subungual melanoma? 47 [Wide excision or reexcision of lesion or minor (local) amputation with margins greater than 2cm] is the correct surgery code for amputation of a finger for melanoma.

Reportability--Pancreas: Is this reportable? Is this benign? If reportable, what histology code and behavior code should be used? A final pathology diagnosis reads: "Cystic pancreatic endocrine neoplasm (CPEN)".

"Cystic pancreatic endocrine neoplasm (CPEN)" is reportable. Assign 8150/3 based on the information provided. We consulted our expert pathologist and he states "Since metastases have been reported in a few, and all the rest of the pancreatic endocrine tumors are now designated malignant, we are safe considering them /3 until proven otherwise. Since most of them are non-functioning, [assign code] 8150/3 unless specified as to G1 (8240/3) or G2 (8249/3)."


Reportability--Brain and CNS: Is "Lhermitte-Duclos disease" is reportable? See discussion.

The MRI states "Lhermitte-Duclos disease" but does not include "dysplastic gangliocytoma of cerebellum"; is this the same as "Lhermitte-Duclos dysplastic gangliocytoma of cerebellum (C716)"?

"Lhermitte-Duclos disease" alone can be interpreted as "Lhermitte-Duclos dysplastic gangliocytoma of cerebellum (C716)" and reportable.The WHO classification for CNS tumors lists this entity as "Dysplastic gangliocytoma of the cerebellum (Lhermitte-Duclos disease)" signifying that the terms are used synonymously.

20051079 Reportability/AmbiguousTerminology: Because there is a caveat in the SEER PCM, 3rd edition to ignore adverbs such as "strongly" when assessing reportability, should a term such as "likely" cancerous be considered reportable given than the expression "most likely" cancerous is reportable?

"Likely cancerous" is NOT reportable.

The CoC, NPCR and SEER have agreed to a strict interpretation of the ambiguous terms list. Terms that do not appear on the list are not diagnostic of cancer.

20081033 Ambiguous terminology: Is the phrase "malignancy is highly considered" reportable given that the phrase "considered to be malignant" is reportable per SINQ 20061094?

"Malignancy is highly considered" is not a reportable ambiguous term.

Diagnoses qualified by the phrase "considered to be malignant" are reportable because this phrase is interpreted as "This diagnosis is malignant."


Reportability/Histology: Would a histology reading"Well-differentiated neuroendocrine neoplasm" of the appendix be reportable? Since the word "tumor NOS" and "neoplasm NOS" both code to 8000, I would assume they would be interchangeable but just wanted to verify.

According to SINQ 20130027 & 20140002 a "Well-differentiated neuroendocrine tumor" of the appendix IS reportable.

"Well-differentiated neuroendocrine neoplasm" of the appendix is reportable. According to the WHO classificationof Digestive System Tumors,"Well-differentiated neuroendocrine neoplasm" of the appendix is synonymous with NET. WHO states on page 13 "The term 'neuroendocrine neoplasm' can be used synonymously with 'neuroendocrine tumor.'"

Neuroendocrine "tumor," or NET G1, is listed in the WHO classification as one of the malignant neoplasms of the appendix.

20051073 Reportability/Behavior--Colon: Is a final diagnosis of "mucosal carcinoid" of the colon reportable with a behavior code 2 [in situ] or 3 [invasive] if the microscopic description states that a "malignancy is not appreciated"? See Discussion.

2002 carcinoid case. Path final diagnosis: sigmoid colon polyp, bx-- sm mucosal carcinoid (1.5mm) w/crush artifact in a colonic polyp showing assoc inflammatory and hyperplastic changes. Micro: due to prominent crush artifact, histologic detail is compromised; however, significant atypia or malignancy is not appreciated.

Our state registry requests that this case be abstracted using the histology code 8240/3 because it is a mucosal carcinoid.

AJCC states TIS as being confined w/i basement membrane w/no extension through muscularis mucosae into submucosa. SEER-EOD codes as invasive: mucosa, lamina propria and muscularis mucosae. Our pathologist goes along with AJCC while we are having to code with SEER rules.

1) Assign /3 to mucosal carcinoid, unless stated to be in situ in the final diagnosis. ICD-O-3 is the reference for assigning the behavior code, not AJCC, EOD or CS.

2) The ICD-O-3 code for carcinoid of the sigmoid colon is C187 8240/3. This is reportable to SEER based on the final diagnosis above. Use the histology stated in the final diagnosis.


MP/H Rules/Histology-Urinary: 1) What is the correct ICD-O-3 morphology code for conventional renal cell carcinoma? Is this clear cell carcinoma or does conventional refer to the general diagnosis?

2) If a patient was diagnosed with invasive papillary urothelial carcinoma of the bladder in May 2011 and returns in February 2013 with invasive urothelial carcinoma of the bladder, what is the correct ICD-O-3 morphology code?

1) Clear cell renal carcinoma, code 8310, is often called conventional renal cell carcinoma. It is specific compared to renal cell carcinoma, NOS, code 8312, a general morphology term for the majority of kidney cancers. See kidney rules H5 and H12 and Table 1 on page 57 of the Kidney Terms and Definitions,

2) Do not change the ICD-O-3 code assigned for the 2011 diagnosis. As you know, the 2013 diagnosis is not a new primary per rule M6.
