Would this situation be 2 primaries - 1993 Renal pelvis and 1994 Bladder with the 2015 being the same primary as 1993 Renal pelvis? Or 3 primaries - 1993 Renal pelvis, 1994 Bladder, 2015 Bladder?
Abstract four primaries, 1993 renal pelvis, 1994 bladder, 2013 bladder, and 2015 bladder.
For the remaining diagnoses, the 2007 MP/H rules apply. The 2013 bladder diagnosis is a new primary per rule M7. The 2014 bladder diagnosis is not a new primary per rule M6. The 2015 bladder diagnosis is a new primary per rule M5.
Reportability--Brain: Is benign lymphangioma of the brain (9170/0) reportable? It is not on the list of non-malignant blood vessel tumors in the National Program of Cancer Registries Clarifications for Central Nervous System (CNS) tumors.
Lymphangioma of the brain or CNS is not reportable. Lymphangioma is a malformation of the lymphatic system. Even though it has an ICD-O-3 code, do not report it.
Reportability--Gallbladder: Is high grade biliary intraepithelial neoplasia of the gallbladder reportable?
High grade biliary intraepithelial neoplasia of the gallbladder is reportable. Assign code 8148/2. It is also known as biliary intraepithelial neoplasia grade 3, or BilIN-3.
MP/H/Histology--Pituitary: Would you code Crooke cell adenoma as 8272/0 pituitary adenoma?
Yes, code Crooke cell adenoma to 8272/0 pituitary adenoma. According to the WHO classification, it is a variant of adrenocorticotropic hormone (ACTH) producing adenoma (8272/0).
Grade/Sarcoma--Breast: Is the correct grade for high grade angiosarcoma of the breast a code 3 or 4? The breast usually uses a three grade system but sarcoma is not a typical histologic type of the breast.
Assign grade code 4 using the sarcoma table. Nottingham or Bloom-Richardson (BR) Score/Grade does not apply to angiosarcomas. This is a good question and points out needed clarification of the grade rules.
Reportability/Behavior--Small intestine: Is a carcinoid tumor, described as benign, reportable? See Discussion.
A segmental resection pathology report states "benign mucosal endocrine proliferation consistent with a 0.3 cm duodenal carcinoid tumor." The diagnosis comment further states, "the separate small endocrine lesion is histologically benign, consistent with a 3 mm carcinoid tumor." This seems to be an example of a description of a microcarcinoid tumor referenced in SINQ 20160011. However, in this new case the pathologist specifically states the tumor is benign.
The WHO definition of microcarcinoid indicates this is a precursor lesion, which seems to indicate it is not malignant. However, SEER's previous answer stated we should report these tumors because the ICD-O-3 definition of carcinoid is 8240/3. Do you think that the mention of the term "benign" in the pathology report is actually related to the size of this lesion? Is the reference to benign mucosal endocrine proliferation referring to the WHO classification (making the case reportable as stated in SINQ 20160011), or is this a situation in which we should apply the Matrix Rule and the case is nonreportable?
This carcinoid tumor, described as benign, is not reportable. According to our expert pathologist consultant, this case is not reportable because the pathologist uses "benign" to describe the mucosal endocrine proliferation and based on that, the neuroendocrine cell proliferation is hyperplasia/benign - not reportable.
First course treatment/Surgery of Primary Site: If a procedure stated to be an "excisional biopsy" doesn't grossly remove the tumor, should Surgery of Primary Site be coded as an excisional biopsy? See Discussion for example.
Would you code an excisional biopsy as Surgery for the following case?
The patient presented with a large protruding polypoid anal canal mass. The diagnosis of malignancy was made following a procedure referred to by the surgeon as an excisional biopsy. The protruding portion of the anal canal mass was excised, but the deep margin was grossly involved. The PE exam after the "excisional biopsy" found a firm mass, 4 cm in length on DRE. Further work-up with imaging showed gross residual disease extending to adjacent skeletal muscle (external anal sphincter). Although the internal/protruding anal canal portion of the tumor was excised, there was clearly extensive residual tumor. The patient underwent definitive concurrent chemoradiation only; subsequent surgery was not planned or performed.
Reportability--Bladder: Please explain the reportability of UroVysion for bladder cancer in the following circumstances.
1. Patient has positive UroVysion test and follow up biopsy is negative. Is this case reportable with a diagnosis date the date of the UroVysion?
2. Patient has positive UroVysion test and follow up biopsy is positive for cancer. Is the diagnosis date of the date of the positive UroVysion or the date of the positive biopsy? Thank you.
Do not report a case based on UroVysion test results alone. Report a case when there is positive histology, a physician statement of malignancy, and/or the patient was treated for cancer.
Reportability--Ovary: Is micropapillary serous carcinoma (MPSC) of the ovary reportable? What are the differences between “noninvasive" and “low malignant potential?" See discussion.
Pathology report reads left ovary: noninvasive low grade (micropapillary) serous carcinoma (MPSC), fragmented; right ovarian excrescence and posterior cul-de-sac: noninvasive implants identified; right ovary: noninvasive low grade (micropapillary) serous carcinoma (MPSC), scattered autoimplants (noninvasive); tumor is present on ovarian surface, noninvasive autoimplants
Noninvasive low grade (micropapillary) serous carcinoma (MPSC) of the ovary is reportable. Assign code 8460/2, applying the ICD-O-3 matrix concept to this noninvasive carcinoma. Noninvasive can be used as a synonym for in situ, ICD-O-3 behavior code /2. See page 66 in the softcover ICD-O-3. Low malignant potential (LMP) means that the neoplasm is not malignant, but has some chance of behaving in a malignant fashion. LMP can be used as a synonym for ICD-O-3 behavior code /1, see page 66.
MP/H/Histology--Thyroid: What is the histology code for primary site of thyroid cancer with the histology of papillary thyroid carcinoma, classical and oncocytic type?
Code the histology to 8342/3, thyroid oncocytic (oxyphillic) papillary carcinoma.
