20170031 | MP/H Rules/Multiple primaries--Penis: How many primaries should be reported for a diagnosis of invasive squamous cell carcinoma (SCC) of the penis in 6/2011, treated with excision and fulguration followed by 10/2014 penile lesion found to be SCC with basaloid features focally highly suspicious for invasion? Clinically, the 2014 tumor is stated to be in situ and recurrent penile cancer and follow-up in 2/2015 indicates there was no evidence of tumor following treatment. Subsequently, in 3/2016 the patient has another penile lesion biopsy showing SCC in situ suspicious for invasion, clinically stated to be recurrent. See Discussion. |
At the central registry, we have accessioned this scenario as three primaries per Multiple Primaries/Histology (MP/H) Rule M10 (diagnosed more than 1 year apart), as the patient was stated to be disease free between each occurrence. However, the diagnosing/treating facility is not reporting these cases due to clinical statements of recurrent disease. This is an example of a case type identified on casefinding audits conducted by our central registry in which we have learned SEER's expectation of MP/H rule application does not match hospital reporting. Can the 2018 version of the MP/H rules more clearly address how this type of clinically recurrent (multiple times) case should be handled? |
Accession three tumors as the tumors were each diagnosed more than one year apart according to the MP/H Rule M10 for Other Sites. And, as you have noted, the patient was free of disease after each diagnosis. The MP/H rules have very clear instructions regarding the word "recurrence." See page 10, specifically A.7., https://seer.cancer.gov/tools/mphrules/2007_mphrules_manual_08242012.pdf SEER will evaluate the MP/H rules in the upcoming revision. |

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

20110046 | MP/H Rules/Multiple primaries--Stomach: If there is no statement of recurrence, how many primaries are to be abstracted when a patient is diagnosed with multiple gastric carcinoid tumors between 12/2003 and 3/2009? See Discussion. |
Are the multiple primary rules applicable when a patient has multiple gastric carcinoid tumors? The patient was diagnosed with carcinoid tumors starting in 12/2003 through 3/2009. According to the 2004 SEER Manual, rule 5, if a tumor with the same histology is identified in the same site at least two months after the original diagnosis, this is a separate primary. The physician does not indicate that the pre-2007 carcinoid tumors were recurrent. The patient does not have familial polyposis syndrome. Should each of the following tumors be a separate primary? 12/2003 - Gastric Polyp Removal - Path: Gastric carcinoid tumor 05/2004 - Stomach body polyp removal - Path: Carcinoid Tumor (endocrine cell tumor) 09/2004 - Single polyp in body removal - Path: Gastric carcinoid 03/2005 - Multiple gastric body polyps removed - Path: Carcinoid tumor 07/2005 - 3 small polyps in fundus removal - Path: Carcinoid tumor 02/2007 - Localized nodularity in lesser curvature - Path: Carcinoid (neuroendocrine) tumor 03/2009 - Stomach body polypectomy - Path: Carcinoid tumor |
Code as a single primary. The histology is carcinoid. Our expert pathology consultant replied as follows: "This patient clearly has a condition driving the proliferation of neuroendocrine cells. Possibilities include hypergastrinemia from a gastrinoma or from response of antral gastrin cells due to achlorhydria from long standing chronic atrophic gastritis, or multiple endocrine neoplasia (MEN1) syndrome (genetically driven). How should these cases be coded given we do not have a way to code the inciting situation. (I suspect the gastroenterologist knows what it is, but we haven't obtained that information.) We do not have an ICD-O-3 code for the underlying condition, MEN1 or hypergastrinemia. Therefore, the only choice is to code the resulting tumor, carcinoid [8240/3]." |

20160003 | MP/H Rules/Multiple primaries--Thyroid: How many primaries should be reported for a diagnosis of Hurthle cell carcinoma (2.7 cm) and papillary carcinoma (0.3 cm) in the thyroid? See discussion. |
SINQ 20110028 includes a note that states "Hurthle cell carcinoma is a synonym for follicular carcinoma according to the WHO." That case is a little different in that the Hurthle cell carcinoma was stated to be a probable follicular variant of papillary carcinoma. The case above does not include that statement.
Is Hurthle cell carcinoma a type of follicular carcinoma? Does rule M6 (follicular and papillary tumors in the thyroid w/in 60 days) apply, report a single primary? Or does rule M17 (tumors with ICD-O-3 histology codes different at the third digit) apply thus leading to multiple primaries (8290 for Hurthle cell and 8260 for papillary thyroid carcinoma)? |
Apply rule M6 and report a single primary.
Hurthle cell carcinoma is a snynonym for follicular carcinoma of the thyroid. |

20140083 | MP/H Rules/Multiple primaries--Thyroid: How many primaries should be reported when a complete thyroidectomy specimen shows two tumors: 1.8 cm papillary carcinoma with tall cell features (8344/3) and a 0.4 cm papillary thyroid carcinoma (8260/3)? See discussion. |
Is papillary thyroid carcinoma an NOS histology qualifying for rule M16, thus leading to a single primary, or would M17 apply (multiple primaries) because the histology codes are different at the second digit (8260 and 8344)? While rule M16 doesn't include papillary thyroid carcinoma in the listed histologies, it seems like it may be an NOS histology for the thyroid. In addition, code 8260/3 is listed as NOS in the ICD-O-3. |
Apply rule M16 and abstract a single primary. These two thyroid tumors, one papillary carcinoma with tall cell features (8344/3) and one papillary thyroid carcinoma, fit the criteria for rule M16, although not explicity listed there. We will clarify this in the next version of the rules. |

|
20180008 | MP/H Rules/Multiple primaries--Thyroid: Is medullary carcinoma of the right lobe of the thyroid, with foci of papillary microcarcinoma in both lobes, one primary with mixed histology (8347/3) or two separate primaries? |
For cases diagnosed prior to 2018 Abstract two primaries, Medullary (8510/3) and papillary microcarcinoma (8260/3). Other sites rule M17 applies. |

|
20091024 | MP/H Rules/Multiple primaries--Urinary: Are diagnoses in bladder, ureter, renal pelvis, and other urinary made prior to 2007 used in determining multiple primaries? See Discussion. |
Per the General Information for MPH, Rule #3, the rules are effective for cases diagnosed January 1, 2007 and after. Do not use these rules to abstract cases diagnosed prior to January 1, 2007. Example: Is a 2006 diagnosis of a renal pelvis primary with the histology 8130/3 and a 2007 diagnosis of a bladder primary with histology 8130/3 "multiple tumors" or is the bladder tumor a new primary because it is a single tumor at the time of diagnosis in 2007? |
For cases diagnosed 2007 or later: Use the 2007 MP/H rules for urinary sites to assess tumors diagnosed in 2007 or later. For the example above, use the 2007 rules to determine whether or not the bladder tumor diagnosed in 2007 is a new primary. Use the Multiple Tumors module when comparing a 2007 or later diagnosis to an earlier diagnosis. Start with rule M3. Stop at rule M8. The 2007 bladder urothelial tumor is not a new primary since there is an existing 2006 renal pelvis urothelial primary. |

20091025 | MP/H Rules/Multiple primaries--Urinary: How should we handle urinary tract tumors diagnosed before the MP rules went into effect when determining the number of primaries to report primaries? How do you apply rules M5, M6 and M8 when an invasive bladder tumor and other urinary site tumors occur before and after the effective date of these rules? See Discussion. |
Example: Patient with a prior in situ carcinoma of the bladder in 11/89, left ureter papillary transition cell carcinoma in situ diagnosed in 5/05, left renal pelvis papillary transition cell carcinoma in situ diagnosed in 8/07 and invasive bladder carcinoma diagnosed in 3/08. When an invasive bladder tumor and other urinary site tumors occur, do you stop with the bladder at rule M5 and M6 never reaching M8? |
For cases diagnosed 2007 or later: Use the 2007 MP/H rules for urinary sites to assess diagnoses made in 2007-2014. Use the multiple tumors module to compare a diagnosis in 2007-2014 to an earlier diagnosis. For the example above, start by comparing the left renal pelvis diagnosis in 8/07 to the earlier left ureter primary diagnosed 5/05. Start with rule M3. Stop at rule M8. The 8/07 renal pelvis diagnosis is not a new primary. Next, compare the 3/08 bladder tumor to the earlier left ureter primary diagnosed 5/05. Start with rule M3. Stop at rule M5. The 3/08 bladder tumor is a new primary because it is an invasive diagnosis following an in situ diagnosis. Use only the more recent of the two earlier urinary diagnoses for comparison. Do not compare the 2007 and later diagnoses to the 11/89 in situ bladder primary in this case. |

20130012 | MP/H Rules/Multiple primaries--Urinary: If topography codes C681-C689 are not included in Urinary Multiple Primary Rule M8, would a subsequent renal pelvis papillary transitional cell carcinoma be a new primary? See Discussion. |
The patient had a papillary transitional cell carcinoma of the bladder and ureter diagnosed in 2010. The primary site was coded to C689 [urinary system, NOS]. The patient was diagnosed with a transitional cell carcinoma of the renal pelvis [C659] in 2012. In applying the MP/H rules to the 2012 diagnosis, rule M8 would be ignored because the primary site of the 2010 primary was coded to C689. The result is that M9 or M10 would be applied which indicates a new primary for the 2012 diagnosis. Should the 2012 renal pelvis carcinoma be a new primary? |
For cases diagnosed 2007 or later, accession a single primary, papillary transitional cell carcinoma of the bladder and ureter [C689, urinary system, NOS] diagnosed in 2010. The steps used to arrive at this decision are: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Urinary MP Rules because site specific rules exist for this primary. Start at the MULTIPLE TUMORS module, rule M3. The rules are intended to be reviewed in consecutive order within a module. This patient has urothelial tumors in two or more of the listed sites (bladder, ureter and renal pelvis) diagnosed within 3 years. When C689 is assigned because tumors of the bladder and tumors of the ureter were determined to be a single primary and the site of origin is not known (as in this example), rule M8 is applied when a subsequent tumor is diagnosed in one of the listed sites. However, if site C689 [urinary system, NOS] was assigned for other unknown urinary primary site situations, rule M8 would not be used. Rule M8 was written specifically for urothelial tumors in the renal pelvis, ureter, bladder and urethra. Paraurethral gland [C681] and overlapping lesions of urinary organs [C688] do not belong in rule M8. We will add this issue to the list of possible revisions for the next edition of the MP/H Rules. |

20180002 | MP/H Rules/Multiple primaries--Urinary: Is a renal pelvis diagnosed 5/2016 a separate primary when the first invasive bladder was 12/2011? Per rule M7, the 5/2016 renal pelvis is more than 3 years later. Does Multiple Primary/Histology (MP/H) rule M7 refer back to the original diagnosis date or to the last occurrence? See Discussion. |
12/30/11 Bladder Biopsy: Diffuse carcinoma in situ of bladder, urothelial cancer at trigone (Stage T1) 1/30/2012 Transurethral resection of the bladder was non-papillary, urothelial carcinoma, focal invasion of lamina propria, staged T1 11/10/14, 9/28/15, 9/26/16, 10/19/17 all had positive bladder cytology of urothelial carcinoma 5/16/16 Left renal pelvis aspirate: positive for malignant cells, urothelial carcinoma 9/26/16 Left renal pelvis aspirate: positive for malignant cells, urothelial carcinoma 10/18/16-11/7/16 Bacillus Calmette-Guerin (BCG) x3 administered into the renal collecting system via ureteral catheter |
For cases diagnosed prior to 2018 This case is a single primary. This patient has not had a disease-free interval as demonstrated by the positive cytologies from 2014 through 2017. The MP/H rules cannot be applied in this case. To answer your question about the timing of rule M7, please see slide 6 in the Beyond the Basics MP/H advanced training, General Instructions, https://seer.cancer.gov/tools/mphrules/training_adv/SEER_MPH_Gen_Instruc_06152007.pdf |
