20140047 | MP/H/Multiple primaries--Urinary: In Aug 2008 Patient was diagnosed with Noninvasive Bladder Cancer. In Oct 2013 Patient was diagnosed with Transitional Cell Carcinoma of Right Ureter involving lamina propria, Noninvasive Transitional Cell Carcinoma Left Ureter and Invasive Transitional Cell Carcinoma of Prostatic Urethra. Is this a new primary and what is the primary site? |
Rule M7 applies when comparing the 2008 diagnosis to the 2013 diagnosis: multiple primaries.
Rule M8 applies to the tumors identified in 2013: single primary.
Based on the information provided, code the primary site for 2013 to C689 because there is no indication of the site of origin among the involved sites. |

20140017 | Multiple Primaries--Heme & Lymphoid Neoplasms: 2012 path report for removal of an "axillary mass" which consists of 80% diffuse large B-cell lymphoma (DLBCL) and 20% follicular lymphoma. In the original manual, Module 6 instructed us to code as a single primary, DLBCL. However, the multiple primary calculator says each disease is a separate primary. When I looked them up in the data base, I did not get an option to review a current manual. Can you please advise? |
Code as a single primary with histology Diffuse Large B-Cell Lymphoma.
In this case, there are two NHLs in the same location at the same time. Apply Rule M4, this is one primary. Per Note 5 under Rule M4, go to Rules PH11and PH15 to assign primary site and histology.
Rule PH11 states to code to the site of the origin (axillary mass) and to diffuse large b-cell lymphoma (9680/3) when DLBCL and any other non-Hodgkin lymphoma (follicular in this case) are present in the same location at the same time.
Using the multiple primaries calculator in this situation will give you two primaries, which is the wrong answer. Use the rules before using the calculator.
To get to the manual, go to the "Help me code for dx year." section. Choose 2010 or later and the most current manual will appear. We recommend that you save a copy of the PDF on your computer. |

20140036 | MP/H Rules/Multiple primaries--Prostate: Is duct carcinoma of the prostate the same as an adeno/acinar carcinoma of the prostate? Specifically, does rule M3 apply when there is an adenocarcinoma of the prostate followed by a duct carcinoma of the prostate or a duct carcinoma followed by adenocarcinoma? |
Rule M3 does not apply to adenocarcinoma followed by duct carcinoma of the prostate or vice versa. Rule M3 pertains to cases of adenocarcinoma and acinar carcinoma. These two terms, adenocarcinoma and acinar carcinoma, are equivalent for the purpose of applying the MP/H rules to prostate cases. See page 77 of the Other Sites Terms and Definitions, http://www.seer.cancer.gov/tools/mphrules/mphrules_definitions.pdf

20140050 | MP/H Rules/Histology--Sarcoma: What would be the morphology code for a low grade myofibroblastic sarcoma of the left distal forearm? I tried several different combinations but the closest I could come up with is myosarcoma. |
Assign code 8825/3. Apply the ICD-O-3 Matrix Concept, Rule F, page 29 of the hardcover ICD-O-3. The WHO Classification of Soft tissue and Bone, page 85, lists low grade myofibroblastic sarcoma, also called myofibrosarcoma, 8825/3. |

20140039 | Reportability--Heme & Lymphoid Neoplasms: Is a statement of "JAK-2 positive polycythemia" reportable? See discussion. |
Polycythemia, NOS is not reportable. However, there is a statement in the Heme Manual Glossary for JAK2 that states, "When JAK2 is positive, the MPN is definitely reportable." Does a positive JAK 2 always mean there is a reportable myeloproliferative disorder or must there also be an associated statement of a reportable neoplasm (e.g., myeloproliferative disorder, polycythemia vera, or essential thrombocythemia)? |
A positive JAK 2 does not always mean there is a reportable myeloproliferative disorder. There must also be an associated statement of a reportable neoplasm (e.g., myeloproliferative disorder, polycythemia vera, or essential thrombocythemia). The glossary entry will be clarified. |

20140006 | Date Therapy Initiated--Corpus Uteri: How should this field be coded for an endometrial primary when the patient undergoes a hysteroscopic polypectomy on 01/08/2014 (Surgery code 25), followed by a TAH/BSO on 02/07/2014 (Surgery code 50)? See discussion. | The hysteroscopic polypectomy showed multiple tissue fragments with invasive endometrioid adenocarcinoma. The hysterectomy and BSO removed an 8.2cm endometrioid carcinoma with no extra-uterine involvement. | Record 01/08/2014 for date therapy initiated assuming there was no therapy prior to this date. A polypectomy is a surgical procedure for purposes of coding date therapy initiated. | 2014 |

20140063 | MP/H Rules--Histology: How is histology coded when a metastatic site is biopsy positive for adenocarcinoma, but the physician clinically states this is cholangiocarcinoma? See discussion. |
The patient underwent a PTA biopsy of a lytic mass showing metastatic adenocarcinoma. Imaging revealed a large hepatic mass consistent with cholangiocarcinoma. The physician's impression on a physical exam note was the PTA biopsy was most consistent with intrahepatic cholangiocarcinoma. However, the PTA pathology report was reviewed at this facility and the final diagnosis was not stated to be cholangiocarcinoma, only adenocarcinoma, NOS.
The priority order for coding histology rules in the MP/H Manual indicates pathology has priority over documentation in the medical record. Following the rules in the MP/H Manual, the histology would be coded as 8140 [Adenocarcinoma, NOS]. While this may be technically correct, it seems that intrahepatic cholangiocarcinoma is often diagnosed as adenocarcinoma on biopsy, but further stated to be cholangiocarcinoma by the physician once other primary sites have been excluded. By applying the rules in the MP/H Manual, cases that seem better characterized as cholangiocarcinomas are being collected as adenocarcinoma, NOS. Should the histology be adenocarcinoma [8140/3] or cholangiocarcinoma [8160/3] for these cases? |
When the physician has reviewed all of the pertinent information, and the physician's opinion is documented stating that the histology is cholangiocarcinoma, code cholangiocarcinoma.
A pathology report from a primary site has the highest priority for coding histology; however, there is no such pathology report in this case. We will review the histology coding instructions and add clarification in the next version. |

20140046 | MP/H/Multiple Primaries--Urinary: Is this one primary with a C689 primary code and morphology 8130/3? Or is this 2 primaries: 1. C679 8130/3 and 2.C680 8120/2. See discussion. |
Urinary: Transitional Cell Carcinoma and open prostatectomy: Path from Bladder: Papillary and solid transitional cell carcinoma of bladder - grade II and III Stage A.
Path from prostatectomy: The prostatic tissue samples shows areas of urothelia carcinoma in situ - related to the tumor present in the bladder.
Conclusion: Prostatectomy showing foci of transitional cell carcinoma in situ of prostatic urethra. |
Abstract a single primary, C679 8130/3. Rules M2 and H4 apply. Transitional cell/urothelial carcinoma in the prostatic urethra is likely an extension from the known bladder TCC in this case, not a separate primary. See prostatic urethra on page 63 in the Urinary Terms and Definitions, http://www.seer.cancer.gov/tools/mphrules/mphrules_definitions.pdf |

20140088 | Reportability--GIST: The 2014 SEER Program Coding and Staging Manual and the answer to SINQ 20100014 appear to conflict with respect to reporting GIST cases. The manual states (p.5, exception 1) that we are to accession the case if the patient is treated for cancer. However, the patient in Example #7 in the SINQ discussion is receiving chemotherapy, but is deemed not reportable. This is a problematic issue in our area, as pathologists prefer using the NCCN “Risk Stratification of Primary GIST by Mitotic Index, Size and Site” table rather than stating whether the tumor is benign or malignant. Although they tell us that moderate or high risk should receive treatment, they will not characterize them as malignant. |
Determining reportability for GIST is problematic because of the reluctance of pathologists to use the term "malignant" for GIST cases. If you can document the pathologist's terminology and case characteristics (e.g. treatment) that correspond to "malignant" for your registry as part of the registry's policies and procedures, you can report those cases as malignant.
The exception cited above in the SEER manual pertains to a clinical diagnosis with a negative pathology report. Normally, the negative pathology report would override the clinical diagnosis and the case would not be reportable. However, if the patient is treated for a malignancy in spite of the negative pathology, report the case.

20140078 | Surgery of Primary Site--Bladder: Is any mention of cautery in the gross description of pathology for a TURBT specimen sufficient to code 22 (excisional biopsy with electrocautery), or does there need to be a statement in the operative report that electrocautery was performed? See discussion. |
Often, pathology for TURBT with non-invasive papillary TCC includes a gross description with a variety of cautery descriptions. For example, "received are three cautery roughened gray-pale pink tissue fragments.” However, the operative report is documented as a "TURBT" with no further description of the procedure. |
Assign code 22 when cautery is mentioned n the gross description of pathology for a TURBT specimen. |
