20150060 | Reportability/MP/H Rules: Where can I find documentation on how to accession malignant tumors in transplanted organs? See discussion. |
A patient was diagnosed with hepatocellular cancer (HCC) in 2010, and underwent a hepatectomy, and then received a donor liver. In 2014, HCC was discovered in the liver once again. This likely is a new primary, but there are no specific rules to cover this. There are many odd situations involving transplanted organs, many of which pose reportability and multiple primary problems. |
Accession the new tumor in the transplanted organ as you would any other new/second primary. As transplants have become more common especially for liver, lung, and kidney, we are seeing more of these types of cases. We are adding instructions to the revised MP/H rules on coding subsequent primaries when they occur in a transplanted organ. We are also looking at adding a data field that will identify cancers/tumors which arose in a transplanted organ. We feel this is important to track for analysis. Until the revised MP/H rules are implemented, we will look at adding general coding instructions to the SEER Program Manual for transplants. |

20150031 | MP/H Rules/Multiple primaries--Colon: This is an unusual case of multifocal colon cancer. The case is staged pT4b,N1b. Per our MP rules, this will be 4 separate primaries. Would this be an exception to the rules; if not now, possibly in future versions of the MP rules for colon cancer? See discussion. |
The path report reads: COMMENT: There is multifocal involvement throughout both bowel segments which combined represent a subtotal colectomy procedure. There are at least 11 tumors, all of which are histologically similar. Given the unusual gross appearance, a representative portion of the largest mass (hepatic flexure) was forwarded to _____ for flow cytometric evaluation. There is chronic active colitis in the background suggestive of idiopathic inflammatory bowel disease, specifically ulcerative colitis. However, no dysplasia is seen in multiple random sections of grossly benign large bowel. ADDENDUM from expert gastroenterologist: The carcinomas are poorly differentiated without specific histologic features but are consistent with colon primaries. These findings are consistent with an MLH1-deficient carcinoma. Given the background chronic active colitis consistent with ulcerative colitis, this likely represents colitis-associated neoplasia which can be associated with multifocality. |
This unusual case of multifocal colon cancer is not an exception to the MP/H rules currently.
The current WHO classification for colon tumors mentions ulcerative colitis (UC) associated colorectal cancers and states they are often multiple. This will be discussed for the next version of the MP/H rules. |

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. |

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. |

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. |

20150005 | Reportability--Skin: Is this case not reportable if the intranasal polyp is covered with cutaneous epithelium (essentially skin) or, is it reportable as a primary intranasal basal cell carcinoma? I have found one article regarding primary intranasal basal cells, which are described as being "very rare". But, I am not sure whether, in those cases, cutaneous epithelium was found.
FINAL DIAGNOSIS: (A) Nasal cavity, polyp, excision: Sinonasal inflammatory polyp with overlying cutaneous epithelium showing foci of superficial (noninvasive) basal cell carcinoma |
Report this case as a basal cell carcinoma, noninvasive, of the nasal cavity, based on the information provided.
The polyp was removed from the nasal cavity (C300) which is a reportable site for basal cell carcinoma. |

20150061 | Reportability--Vulva: Is this reportable? We have begun to see the following diagnosis on biopsies of the vulva with the statement below. The diagnosis is being given as simply VULVAR INTRAEPITHELIAL NEOPLASIA, no grade is noted. See discussion. |
The note explains: The International Society for the Study of Vulvovaginal Disease (ISSVD) in 2004 revised its classification of VIN by eliminating VIN 1 and combining VIN 2 and VIN 3 into a single category (see table below). Classification of VIN (usual type) ISSVD [International Society for the Study of Vulvovaginal Disease]1986 classification 2004 classification VIN 1 VIN2 VIN3 VIN Note: VIN 2 and VIN 3 combined into single [non-graded] category, VIN Reference: Scurry J and Wilkinson EJ. Review of terminology of precursors of vulvar squamous cell carcinoma. Journal of lower genital tract disease, 2006; 10(3): 161-169 |
Vulvar intraepithelial neoplasia with no grade specified is not reportable. Reportability instructions have not changed. See page 11 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf |

20150013 | Surgery of Primary Site: What is the most extensive, invasive or definitive surgical procedure when the second surgical procedure performed has a lower surgery code? See discussion.
|
Examples
8/xx/13 TURBT with path specimen (27): Papillary Urothelial Carcinoma, HG 9/xx/13 Bladder fulgeration w/o path specimen (12)
5/xx/14 Segmental Mastectomy(24): Ductal carcinoma with <1mm marg 6/xx/14 Breast Re-excision (23): Residual ductal carcinoma 1.5mm, marg neg |
The code in Surgical Procedure of Primary Site should correspond to the most invasive, extensive, or definitive surgery when the patient has multiple surgical procedures of the primary site even if there is no residual tumor found in the pathologic specimen from the more extensive surgery. The timing of the procedures does not affect the code choice.
Assign code 27 for the first example. Assign code 24 for the second example. |

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. |

20150003 | Reportability/Behavior: Is the following reportable, and if so, what is the histology code? Final Diagnosis (on multiple conjunctive excisions): Conjunctiva - primary acquired melanosis with atypia (see note). Note: "In all 3 specimens the process extends to the margins of excision. Complete extirpation is recommended (primary acquired melanosis with atypia is considered melanoma in situ). |
Do not report primary acquired melanosis with atypia.
According to our expert pathologist consultant, "There has been a lot of debate in the literature about the diagnostic criteria, terminology, and natural history of primary acquired melanosis [PAM]. Your case comes down squarely on the main issue, which is whether PAM with atypia should be regarded as melanoma in situ. In most studies it appears that PAMs with no atypia or mild atypia do not progress to melanoma, and only a small percentage of those with severe atypia do so." "PAM, even with atypia, is not melanoma in situ, and should not be reported."
