20140056 | MP/H--Bladder: Are 8130 and rule H12 correct for this case? Bladder with papillary urothelial carcinoma with squamous cell differentiation. |
Rule H8 applies, code the histology with the numerically higher ICD-O-3 code which is papillary transitional cell carcinoma, 8130.
Based on the information provided, there is a single bladder tumor, papillary urothelial carcinoma with squamous cell differentiation. Urinary sites rule H12 does not apply because this is a single tumor, not multiple tumors. In the single tumor H rules, H3 does not apply as this rule does not include papillary transitional cell carcinoma. Rule H4 is papillary carcinoma or papillary transitional cell carcinoma and refers you to Table 1. Table 1 does not list papillary urothelial carcinoma with squamous cell differentiation because there is no ICD-O-3 code for this histology. Table 1 does list transitional cell carcinoma with squamous differentiation as code 8120, however, the papillary transitional cell carcinoma is the higher code, 8130. We will review this situation for the next version of the rules. |

20140084 | Histology--Heme & Lymphoid Neoplasms: Should the 1995 diagnosis be changed to plasmacytoma? A 1995 case on the central registry database indicates that MRI and bone surveys revealed a pubic ramus lesion that was biopsied. There are no other bone lesions. A bone marrow biopsy was negative. The pathologist's diagnosis at that time was "Plasma Cell Myeloma". In 2013 there was a positive bone marrow biopsy and a diagnosis of Plasma Cell Myeloma. In 2013, a history of "sequential plasmacytomas since 1995" was mentioned. Since the 1995 diagnosis was only a solitary bone lesion with no marrow involvement, it certainly seems to fit a diagnosis of plasmacytoma better than myeloma. |
Do not change the 1995 diagnosis in this case. It is best to code the histology according to information from the time of the diagnosis. Using information obtained many years later is less reliable. |

20140031 | MP/H Rules: Regarding rules for Renal Pelvis, ureters, bladder & urethra - Please clarify Rule M8. Rule M8 references Table 1, but table 1 is a table of histologies not primary sites, Rule M8 also seems to contradict Table 2 and Rule M10. Does it matter where the first primary is, ie bladder then urethra or bladder then renal pelvis? |
Table 2 does not apply to diagnoses in 2007 and later. A watermark over (or near) Table 2 states "Do not use for cases diagnosed on or after 2007." Table 2 lists previous SEER site groupings for cases prior to 2007.
The MP/H rules are in hierarchical order. Use the first rule that applies. When Rule M8 applies, there is no need to check Rule M10. Rule M8 is for the urinary sites listed and derives single primary. Rule M10 is for all sites, except the sites listed in Rule M8, and derives multiple primaries.
It does not matter where the first primary is, i.e. bladder then urethra or bladder then renal pelvis. If there are two or more tumors in two or more of these four sites listed in Rule M8 with histologies listed on Table 1, abstract as a single primary. |

20140058 | Reportability--Pancreas: Is a solid pseudopapillary neoplasm of the pancreas reportable? |
Solid pseudopapillary neoplasm of the pancreas is reportable. According to the WHO classification, it is a "low-grade malignant neoplasm…[which] frequently undergoes hemorrhagic-cystic degeneration and occurs predominantly in young women."
Assign topography code C25 with the appropriate 4th digit. Code the histology as 8452/3. |

20140038 | MP/H Rules/Multiple Primaries--Urinary: How many primaries are there and which MP rules apply in this scenario? See discussion. |
Patient has 2 tumors in the left ureter; one is transitional cell (8120) and one is papillary transitional cell (8130). Rule M6 says BLADDER tumors with any combination of the following histologies ... are a single primary. But this is not a bladder case. Rule M8 says urothelial tumors in 2 or more of the following sites are a single primary... but this is not in 2 or more sites. Rule M9 then says histologies different at the 1st, 2nd, or 3rd digit are separate primaries. That makes this 2 primaries, but I do not think this should be 2 primaries. |
Rule M9 applies. Abstract 2 primaries.
We will evaluate this scenario for the next version of the multiple primary rules. |

20140049 | Reportability--Brain and CNS: Is Tuberculum sellae meningioma reportable? Is it same as sphenoidale meningioma? Path: Brain tuberculum tumor resection: Meningioma, WHO grade I. |
Revised answer based on ST rules Yes, a Tuberculum sella meningioma is reportable if diagnosed 2004 or later. Code the primary site C700, cerebral meninges. It is a meningioma originating from the meninges of the Tuberculum sellae, which is part of the sphenoid bone. |

20140003 | Surgery of Primary Site/Surgical Procedure of Other Sites--Endometrium: How are these fields coded for an endometrial primary when the patient undergoes a radical tumor cytoreduction including modified radical hysterectomy, BSO, omentectomy, resection of intra-abdominal and intrapelvic implants, and partial cystectomy? See discussion. | When other regional sites (besides the omentum) are removed with the primary site, how is Surgical Procedure of Other Site coded? There is no cytoreduction surgery code for endometrial primaries, and this patient does not appear to qualify for any of the specific pelvic exenteration codes. Per SINQ 20091118, an omentectomy is not coded in the Surgical Procedure of Other Site field when it is performed with a hysterectomy. |
In general, record surgery of sites/organs not covered in the surgery of primary site codes under surgery of other site. For this case, code the partial cystectomy under surgery of other site. As you point out, the omentectomy is not recorded under surgery of other site when performed with a hysterectomy for an endometrial primary. | 2014 |

20140062 | MP/H Rules/Multiple Primaries--Lung: Does lung MP/H Rule M6 apply to synchronous tumors only, metachronous tumors only, or both? See discussion. |
How many primaries should be reported when a patient has a history of RLL adenocarcinoma diagnosed on 10/8/2009 followed by diagnoses of LUL adenocarcinoma on 10/5/2012 and a RUL adenocarcinoma on 3/26/2014?
We applied Rule M6 to the 10/5/2012 diagnosis of LUL adenocarcinoma and reported an additional primary. However, we are unsure how to apply the MP/H rules for the 3/26/2014 RUL adenocarcinoma.
Should we apply Rule M8 because the RUL adenocarcinoma was diagnosed more than 3 years after the original RLL adenocarcinoma and then apply M6 because the RUL and LUL indicate a single tumor in each lung (resulting in a third primary); or does Rule M12 apply because there has been more than a single tumor in each lung (no new primary)? |
Assuming each of the three diagnoses is a single tumor and there are no other tumors in either lung, abstract two primaries: 1 in the RLL diagnosed on 10/8/2009 and 1 in the LUL diagnosed on 10/5/2012. Do not abstract the 3/26/2014 diagnosis as a new primary.
Rule M6 applies to the 2009 and 2012 diagnoses. Rule M12 applies to the 2012 and 2014 diagnoses. Do not compare the 2014 diagnosis to the 2009 diagnosis. Always compare the latest diagnosis to the most recent previous diagnosis in cases like this. |

20140053 | Multiple primaries--Heme & Lymphoid Neoplasms: Is this abstracted as one primary or two?
5/2/13 Bone Marrow biopsy: myelodysplastic syndrome with approaching to acute myeloid leukemia with del 5q and 7q deletions. FISH: deletion of chromosome 5q and deletion of chromosome 7q detected.
I checked the Heme DB manual and there is no term "With approaching to". I checked the Multiple Primary calculator and it says new primary. My interpretation is that the myelodysplastic syndrome is in the process of transforming to acute myeloid leukemia. |
Abstract a single primary, myelodysplastic syndrome with del 5q and 7q deletions (9986/3). This neoplasm can transform to acute myeloid leukemia (AML); however, "with approaching to" cannot be used to report this AML. |

20140029 | MP/H Rules/Histology-Urinary: 1) What is the correct ICD-O-3 morphology code for conventional renal cell carcinoma? Is this clear cell carcinoma or does conventional refer to the general diagnosis?
2) If a patient was diagnosed with invasive papillary urothelial carcinoma of the bladder in May 2011 and returns in February 2013 with invasive urothelial carcinoma of the bladder, what is the correct ICD-O-3 morphology code? |
1) Clear cell renal carcinoma, code 8310, is often called conventional renal cell carcinoma. It is specific compared to renal cell carcinoma, NOS, code 8312, a general morphology term for the majority of kidney cancers. See kidney rules H5 and H12 and Table 1 on page 57 of the Kidney Terms and Definitions, http://www.seer.cancer.gov/tools/mphrules/mphrules_definitions.pdf
2) Do not change the ICD-O-3 code assigned for the 2011 diagnosis. As you know, the 2013 diagnosis is not a new primary per rule M6. |
