20150002 | 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.
1. Do not report the case.
2. Report the case based on the positive biopsy. |

20150009 | Multiple Primaries/Behavior--Lung: When a patient has an invasive lung primary, how do in situ tumors of the lung affect the determination of multiple primaries? See discussion. |
How many primaries should be reported when a 12/19/14 RUL lung wedge resection shows: 2.0 cm invasive adenocarcinoma (8140/3) and an additional RUL wedge resection during the same procedure shows: multifocal adenocarcinoma in situ (bronchioloalveolar carcinoma), non-mucinous type (8252/2) size: 1 mm – 2 mm; followed by a 2/12/15 left upper lobectomy also showing Adenocarcinoma, invasive at several foci, with a prominent bronchioloalveolar (in situ) component….tumor focality: multifocal (10 cm mass, 6 cm mass and numerous smaller foci)? |
Most often when the invasive tumor and the in situ component are in the same lung and are the same histology, rule M12 (example 3) applies and this is a single primary. If the first wedge resection included part of the tumor and the in situ was not separate from the tumor, it is a single primary. We suspect that the margins were positive on the first wedge specimen which prompted the second wedge resection where the in situ was found. In addition, terminology for lung malignancies is undergoing change: what was called BAC (invasive) is now called adenocarcinoma in situ. |

20150025 | Primary Site--Lung: What are the guidelines for coding primary site when a lung tumor is described as a hilar mass? See discussion. |
At a recent meeting, one registry stated that they apply the following guidelines. 1) If the tumor is described as a hilar mass and there is no mention of LN involvement, Primary Site is coded to hilum (C340) 2) If there is LN involvement along with the mention of a hilar mass, then Primary Site is coded to C349 |
Assign primary site code C340 when a lung tumor is described as a hilar mass. |

20150021 | MP/H Rules/Histology--Skin: How is histology coded for an "endocrine mucin-producing sweat gland carcinoma with transformation to mucinous carcinoma"? See Discussion. |
Endocrine mucin-producing sweat gland carcinoma (EMPSCG) is a rare type of low-grade sweat gland carcinoma. Some journal articles indicate that most patients with EMPSCG have coexisting mucinous carcinomas, suggesting that EMPSCG is a precursor to invasive mucinous carcinoma of the skin. Sweat gland carcinoma has its own histology code per the ICD-O-3 (8400/3); should an endocrine mucin-producing sweat gland carcinoma also be coded as 8400/3? If so, would the correct histology for the skin case above be mucinous carcinoma (8480/3) per Rule H17? Conversely, if the terms "mucin-producing" are referring to mucin-producing carcinoma, and not referring to the sweat gland carcinoma, would the histology be coded 8481/3 (mucin-producing carcinoma)? |
Assign 8480/3.
There is no mixed ICD-O-3 code for EMPSCG. Both histologies are in the mucinous family: mucinous adenocarcinoma (8480/3) and sweat gland carcinoma (8400/3). Apply Other sites rule H17 and code the numerically higher ICD-O-3 code (8480/3).
Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a rare low-grade sweat gland carcinoma with a strong predilection to the eyelid region. It is histologically analogous to endocrine ductal carcinoma/solid papillary carcinoma of the breast and is characterized by a multinodular solid cystic mucinous tumor with immunoreactivity to neuroendocrine markers. Only 20 cases of this unusual tumor have been reported. |

20150023 | MP/H Rules/Histology--Thyroid: When is 8341/3, papillary microcarcinoma coded? The code description in ICD-O-3 is followed by (C739), yet there are two SINQ answers that tell us specifically to not use this code for thyroid primaries. Even the first revision of ICD-O-3 still carries the (C739) as part of this code, which goes against SINQ 20110027 and 20081127. |
Per the WHO Tumors of Endocrine Organs, for thyroid primaries/cancer only, the term micropapillary does not refer to a specific histologic type. It means that the papillary portion of the tumor is minimal or occult (1cm or less in diameter) and was found incidentally. WHO does not recognize the code 8341 and classifies papillary microcarcinoma of the thyroid as a variant of papillary thyroid and thereby should be coded to 8260. If the primary is thyroid and the pathology states papillary microcarcinoma or micropapillary carcinoma, code 8260 is correct. This information will be included in the upcoming revisions to the MP/H manual. |

20150064 | Primary site--Head & Neck: When there is invasive in one subsite and in situ in another, do you code the subsite with the invasive only? Would the correct site be C320, C328, or C329? See discussion. |
LARYNGOSCOPY - ENDOLARYNGEAL EXAM WAS GROSSLY UNREMARKABLE EXCEPT THAT SHE APPEARS TO HAVE A T1A SQUAMOUS CELL CARCINOMA OF THE RIGHT TRUE VOCAL FOLD. IT EXTENDS FROM ALMOST THE ANTERIOR COMMISSURE ALL THE WAY BACK TO THE VOCAL PROCESS AND IS EXOPHYTIC IN NATURE. IT DOES NOT EXTEND INTO THE VENTRICLE OR ONTO THE FALSE VOCAL FOLD. NO SUBGLOTTIC EXTENSION IS SEEN. A. RIGHT POSTERIOR FALSE VOCAL CORD FOLD, BIOPSY: SQUAMOUS CELL CARCINOMA IN SITU. B. RIGHT POSTERIOR TRUE VOCAL CORD FOLD, BIOPSY: SQUAMOUS CELL CARCINOMA, SUSPICIOUS FOR INVASION. C. RIGHT MID TRUE VOCAL CORD, BIOPSY: SQUAMOUS CELL CARCINOMA, SUSPICIOUS FOR INVASION. D. RIGHT ANTERIOR TRUE VOCAL FOLD, BIOPSY: INVASIVE AND IN SITU SQUAMOUS CELL CARCINOMA, MODERATELY DIFFERENTIATED. |
See the Head & Neck Terms and Definitions for guidance on coding the primary site, pages 17-18, http://seer.cancer.gov/tools/mphrules/mphrules_definitions.pdf
Based on the information provided, use the statement from the endoscopy report and assign primary site to right true vocal fold [cord], C320. |

20150049 | Reportability--Brain and CNS: Is pseudotumor cerebri reportable? |
Pseudotumor cerebri is not reportable. It is not a neoplasm. The pressure inside the skull is increased and the brain is affected in a way that appears to be a tumor, but it is not a tumor. |

20150038 | Reportability/MP/H Rules/Histology: Is malignant perivascular epithelioid cell tumor (PEComa) reportable, and if so, what is the histology code? |
Malignant perivascular epithelioid cell tumor (PEComa) is reportable because it is malignant. Assign 8005/3 to malignant PEComa.
We consulted an ICD-O-3 expert who explained that some PEComas such as angiomyolipoma and lymphangiomyomatosis have specific ICD-O codes and their malignant counterparts may be coded to 8860/3 and 9174/3 respectively. There are no separate ICD-O codes for other specific PEComas, e.g., clear cell “sugar” tumor of lung, clear cell myomelanocytic tumor of the falciform ligament and some “unusual” clear cell tumors occurring in other organs—or for PEComa, NOS. These PEComas may therefore be coded to 8005 as clear cell tumors NOS; in other words as clear cell tumors that are not clear cell variants of carcinomas, sarcomas, or other specific tumor type.
Please note, PEComa is non-specific as to behavior. Unless the pathologist states that it is malignant, (as was the case for this question), the default code is 8005/1 (non-reportable). |

20150059 | Primary Site--Liver: What is the topography code for combined hepatocellular carcinoma/cholangiocarcinoma (M-8180/3) especially when there is no documentation that intrahepatic bile duct is the tumor site? Reports usually just indicate a liver mass(es) but since the intrahepatic ducts are within the liver, is the code C221 due to the cholangiocarcinoma component, thus making the case stageable? |
If there is no further information about where the cancer originated, assign C220. Use ICD-O-3 as the source for coding topography. The topography code associated with combined hepatocellular and cholangiocarcinoma (8180/3) is C220 when there is no other information available, according to ICD-O-3. |

20150045 | 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. |
