Report Question ID Question Discussion Answer Year
20071093 Reportability--Brain and CNS: In addition to Schwannoma, are there additional types of benign tumors that arise in peripheral nerves along the spinal cord that are not reportable? See Discussion.

Are neuroepitheliomatous neoplasms such as ganglioneuroma, gangliocytoma, ganglioglioma occurring along the spinal cord reportable? Are nerve sheath tumors such as neuroma occurring along the spinal cord reportable? Angioma?

Reference: SINQ 20051071; Primary Central Nervous System Tumors, NPCR Training Materials 2004

Reportability depends on the location of the tumor. Tumors in the following sites are reportable:

  • C700 - C709

  • C710 - C719

  • C720 - C729

  • C751 - C753

    • Benign and borderline tumors of the peripheral nerves (C47_), including peripheral nerves along the spinal cord, are not reportable.

    Please note: spinal schwannomas arising in the nerve root or spinal dura are reportable.

    		20071092 Reportability/Primary Site--Brain and CNS: Is a chondroma, NOS or a chondroblastoma, NOS that occurs in an intracranial site or along the spinal cord reportable? See Discussion.

    In ICD-O-3, chondroma and chondroblastoma are site-associated morphologies for bone. If a chondroma or a chondroblastoma occurs along the spinal cord, is this one of those situations where we can be quite comfortable with a default site to bone and not to spinal cord?

    Reference: ICD-O-3; Primary Central Nervous System Tumors, NPCR Training Materials 2004; SINQ 20021152

    Chondroma, NOS or chondroblastoma, NOS occuring in intracranial sites or along the spinal cord are not reportable.

    Chondroma, NOS and chonroblastoma, NOS are benign tumors of the bone itself, not the intracranial contents.

    		20071090 Multiplicity Counter/Type of Multiple Tumors--Breast: How are these data items coded for a single breast primary composed of both in situ and invasive disease when measurements are provided for both the invasive and in insitu components? See Discussion. Breast cancer, invasive duct carcinoma with DCIS, 1.3 cm, DCIS 3.7 cm. "The in situ carcinoma is very extensive in this lumpectomy. It is present contiguously from sides 1A through 1L sparing only the final 8 mm of medial margin. In situ and invasive carcinoma are prominently present along almost the entire superior margin." Is the mult counter 02 with Type of mult tumor 30, or one tumor? Because there are individual measurements for each of these tumors, code the multiplicity counter 02 [Two tumors present]. Code Type of Multiple Tumor as 30 [In situ and invasive]. 2007
    		20071089 CS Extension--Ovary: Are "non-invasive implants" identified per pathology coded differently than "invasive 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.No, non-invasive and invasive implants are not handled differently in collaborative staging for ovary.

    		20071088 Type of Multiple Tumors--Lung: Is this field coded to 40 [Multiple invasive] or 80 [Unk in situ or invasive] when only one nodule is biopsied of multiple existing nodules for a reported single lung primary? See Discussion.

    The right lung has 4 tumor nodules in the upper lobe. Biopsy of one tumor is positive for moderately differentiated adenocarcinoma. No other work up performed.

    Should code 40 be used because we dont know the behavior of the other nodules?

    		 The best code to use in this case is 40 [multiple invasive]. For lung only, it is assumed that all of the tumors are the same histology and that all are invasive. 2007
    		20071087 MP/H Rules/Multiple Primaries--Breast: How many primaries are abstracted when bilateral breasts contain DCIS? Is a physician statement referring to this situation as one primary ignored? See Discussion. Patient has microcalcifications both breasts. Has bilateral mastectomy. Path report states Left breast multifocal DCIS predominantly micropapillary. Right breast two foci of DCIS micropapillary.

    For cases diagnosed 2007 or later:

    There are two primaries in this case.

    Using the 2007 MP/H rules for breast, go to the multiple tumors module and start with Rule M4. Stop at rule M7. Tumors on both sides (right and left) are multple primaries.

    Always use the 2007 Multiple Primary rules to determine the number of primaries. Do not use the physician statement.

    		20071086 Histology--Pancreas: How is a "gastrin and somatostatin producing endocrine neoplasm" coded that has lymph node metastasis?

    The best code available for this situation is 8153/3 [Gastrinoma, malignant].

    Many pancreatic endocrine tumors produce more than one peptide, such as gastrin and somatostatin in this case. ICD-O-3 does not provide a code for pancreatic endocrine tumors which produce more than one peptide. According to the WHO Classification of Tumours of Endocrine Organs, there is a distinct hormonal syndrome associated with gastrin producing tumors, and not with many of the somatostatin producing tumors. Therefore, our pathologist consultant advises us to code to gastrinoma in this case.

    		20071085 CS Tumor Size/CS Extension--Prostate: Because prostatectomy results are excluded from the CS Extension field for prostate, is code 95 [No evidence of primary tumor] accurate to reflect bilateral lobe involvement of prostate cancer when it is incidentally found following a radical cystectomy for a bladder primary? Why must tumor size be 000 when the CS Extension code is 95?

    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.Code prostate CS Extension to 99 [Extension unknown] and code CS Tumor Size according to the information available from the surgery.

    CS Extension code 95 [No evidence of primary tumor] should be used only in that rare situation when the only evidence of disease is distant mets or lymph node involvement, no primary tumor found. That is why CS tumor Size must be 000 when CS Extension code 95 is used.

    		20071084 MP/H Rules/Histology--Prostate: How is an "acinar adenocarcinoma with focal large duct adenocarcinoma" coded?

    For cases diagnosed 2007 or later:

    As long as this is NOT urothelial carcinoma extending to the prostatic ducts, code histology to 8140/3 [adenocarcinoma] using rule H10.

    Do not code histologies designated as "focal."

    		20071083 MP/H Rules/Multiple Primaries--Bladder/Renal Pelvis: Is a non-invasive papillary transitional cell carcinoma of the bladder diagnosed one year after the occurrence of an invasive papillary transitional cell carcinoma of the renal pelvis reported as one or two primaries?

    For cases diagnosed 2007 or later:

    This is a single primary with renal pelvis as primary site.

    Use the 2007 MP/H rules to determine if the 2007 diagnosis is a new primary. Use the Urinary rules, multiple tumors module. Start with rule M3. Follow the rules down to Rule M8 and stop. This is an example of implantation effect.
