20120063 | Reportability--Pancreas: Are neuroendocrine "tumors" reportable and are they synonymous with neuroendocrine "carcinoma"? See Discussion. | Example: Pancreatic mass that probably represents a neuroendocrine tumor is staged as cT2N0M0. | According to the World Health Organization (WHO) pancreatic neuroendocrine tumors (NET) are malignant. They are reportable.
For pancreas primaries, code NET, G1 (well differentiated) to 8240/3; NET G2 (moderately differentiated) to 8249/3; and nonfunctional NET, GI or G2 to 8150/3. The histology code for neuroendocrine carcinoma (NEC) is 8246/3, large cell NEC is 8013/3 and small cell NEC is 8041/3. |

20120080 | MP/H Rules/Multiple primaries--Kidney, renal pelvis/Bladder: How many primaries are accessioned if the patient was diagnosed with transitional cell carcinoma in situ of the renal pelvis in October 2006, TCC in situ of the bladder in July 2008 and TCC in situ of the ureter in November 2009?. See Discussion. | Per MP/H rule M8, the TCC in situ of the bladder diagnosed in July 2008 is the same primary as the TCC in situ of the renal pelvis diagnosed in October 2006. Should the new TCC in situ of the ureter diagnosed in November 2009 be a new primary per rule M7 because the renal pelvis TCC in situ was diagnosed in 2006? Or does the 3 year time frame for rule M7 start from the date of the last recurrence (July 2008)? | Abstract two primaries for this scenario per Rule M7. The first primary is the renal pelvis in Oct. 2006; the second primary is the ureter in Nov. 2009. The bladder tumor in July 2008 is not a new primary per Rule M8.
Compare the diagnosis date of the current (most recent) tumor to the diagnosis date of the original tumor. This applies even if the patient had six occurrences in-between these dates; you still compare the current tumor to the diagnosis date of the original tumor and ignore recurrences in this process.

20120087 | MP/H Rules/Histology--Kidney: How is the histology coded and what rule(s) apply for "cyst associated renal cell carcinoma," "cystic renal cell carcinoma," and "cystic renal cell carcinoma, clear cell type"? See Discussion.
|
Per SINQ 20031008, these histologies were all coded as 8316/3 [cyst associated renal cell carcinoma]. What are the correct codes for these histologies using the 2007 MP/H Rules?
|
For cases diagnosed 2007 or later, the correct histology code for both cyst associated renal cell carcinoma and cystic renal cell carcinoma is 8316/3. The histology code for cystic renal cell carcinoma, clear cell type is 8255/3.
The steps used to arrive at these decisions are:
Step 1: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Kidney Histology rules because site specific rules have been developed for this primary.
Step 2: For the first histology, cyst associated renal cell carcinoma, start at the SINGLE TUMOR module, Rule H1. The rules are intended to be reviewed in consecutive order within a module. Stop at Rule H5. According to this rule you are to use Table 1 if you have a renal cell carcinoma and mention of a more specific renal cell type. To locate Table 1, go to Kidney under the Terms & Definitions section. Per Table 1, titled Renal Cell Carcinomas and Specific Renal Cell Types, "cyst associated" is a specific type of renal cell carcinoma. Code the histology to 8316/3 [cyst associated renal cell carcinoma].
Step 3: For the second histology, cystic renal cell carcinoma start at the SINGLE TUMOR module, Rule H1. The rules are intended to be reviewed in consecutive order within a module. Stop at Rule H5. As in the previous example you are to use Table 1 if you have a renal cell carcinoma and mention of a more specific renal cell type. Per Table 1 "cystic" is a specific type of renal cell carcinoma. Code the histology to 8316/3 [cystic renal cell carcinoma].
Step 4: For the third histology, cystic renal cell carcinoma, clear cell type, start at the SINGLE TUMOR module, Rule H1. The rules are intended to be reviewed in consecutive order within a module. Stop at Rule H6 which states you are to code histology to 8255 (adenocarcinoma with mixed subtypes) when there are two or more specific renal cell carcinoma types. To determine whether "clear cell" and "cystic" are types of renal cell carcinoma use Table 1 again. According to Table 1, both cystic and clear cell are specific types of renal cell carcinoma. Code the histology as 8255/3 [adenocarcinoma with mixed subtypes].

20120070 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a bone marrow biopsy shows myelodysplastic syndrome - refractory anemia with excess blasts type 2 (RAEB-2) and myelofibrosis? See Discussion. | Should the myelofibrosis be accessioned as a second primary? Or is it a descriptor of the MDS/RAEB-2? The multiple primaries calculator shows 9983/3 and 9961/3 represent two primaries. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Accession a single primary per Rule M2 which indicates you are to abstract a single primary when there is a single histology. Code the histology to 9983/3 [refractory anemia with excess blasts type 2 (RAEB-2)].
Per Appendix F, myelofibrosis, NOS, is NOT a synonym for primary myelofibrosis. Myelofibrosis, NOS, if not specified to be myelofibrosis, therefore, is not reportable.
Per PH29, code the specific histology when the diagnosis is one non-specific (NOS) histology (MDS) and one specific histology (RAEB-2) AND the Multiple Primary Calculator confirms the specific histology and NOS histology are the same primary (which it does).
Myelodysplastic syndrome, NOS is a generic disease description. In most cases, NOS histology is only the provisional diagnosis; the physician will run further diagnostic procedures and look for various clinical presentations to identify a more specific disease. The more specific myelodysplastic syndromes are: refractory anemia; refractory neutropenia; refractory thrombocytopenia; refractory anemia with ring sideroblasts; refractory cytopenia with multilineage dysplasia; refractory anemia with excess blasts; and refractory cytopenia of childhood. If the characteristics of a specific subtype of MDS develop later in the course of the disease, change the histology code to the more specific diagnosis.

20120021 | Multiple primaries--Heme & Lymphoid Neoplasms: How are the terms "chronic" and "acute" used to help determine the number of primaries to be abstracted and what rule applies when a diagnosis of diffuse large B-cell lymphoma is followed two years later by a diagnosis of follicular lymphoma, grade 3A of 3? See Discussion. |
7/31/08 Biopsy of the left supraclavicular lymph node diagnosed Stage IIIB DLBCL [9680/3] 10/14/10 Biopsy of a right supraclavicular lymph node diagnosed follicular lymphoma, grade 3A or 3 [9698/3]. Which multiple primary rule applies to determine the number of primaries to report? Is Rule M4 ignored? Does Rule M13 apply because follicular lymphoma normally transforms to DLBCL? Is this still a transformation because the follicular lymphoma came AFTER the DLBCL (the "acute" reverted to "chronic")? Or does Rule M15 apply, and the Multiple Primaries Calculator should be used to determine the number of primaries to report? Are "transformations" the acute phases of the more chronic disease? The Heme Manual and previous training sessions do not make this apparent. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. This case should be accessioned as two primaries per Rule M13. Code the histology for the 7/31/08 diagnosis to 9680/3 [diffuse large B-cell lymphoma] and the code the histology for the 10/14/2010 diagnosis to 9698/3 [follicular lymphoma, grade 3A of 3]. Rule M13 applies to this case because the neoplasm was originally diagnosed in the blast or acute phase (DLBCL) and reverted to a less aggressive or chronic phase (follicular lymphoma) after treatment. Per the "Transformations to" section in the Heme DB for follicular lymphoma, grade 3 transforms to diffuse large B-cell lymphoma [9680/3]. This means that the follicular lymphoma is the chronic neoplasm and that DLBCL is the acute neoplasm. In this case, the chronic neoplasm was diagnosed after the acute neoplasm was diagnosed and treated (with chemotherapy). Do not Stop at Rule M4 because diffuse large B-cell lymphoma and follicular lymphoma (both NHL's) were not present in the same node(s) AT THE SAME TIME.

20120051 | MP/H Rules/Histology--Breast: What histology code for a diagnosis of pleomorphic lobular carcinoma in situ? | For cases diagnosed 2007 or later, code the histology as lobular carcinoma, in situ [8520/2].
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 Breast Histo rules because site specific rules exist for this primary.
Start at the SINGLE TUMOR: IN SITU CARCINOMA ONLY module, Rule H1. The rules are intended to be reviewed in consecutive order. Stop at the first rule that applies to the case you are processing. Code the histology to lobular carcinoma in situ [8520/2] because this is the only histologic type identified.
Pleomorphic lobular carcinoma is a variant of lobular carcinoma which does not have an ICD-O-3 code. It is still a lobular carcinoma. The identification of the variants of lobular carcinoma was a relatively recent discovery and the information was not available when the 2007 MP/H Rules were written. All of the lobular variants will be included in the next revision of the MP/H Rules. |

20120061 | MP/H Rules/Multiple Primaries--Ovary: How many primaries are accessioned and which multiple primary rule applies for a patient diagnosed with a carcinosarcoma of the left ovary and a serous carcinoma of the right ovary? See Discussion. |
The patient underwent a debulking surgery showing a 20.5 cm carcinosarcoma with focal areas of high grade serous carcinoma and extensive high grade stromal sarcoma in the left ovary. The right ovary showed only a high grade serous carcinoma with extensive involvement of the ovarian parenchyma but no sarcomatous elements. While carcinosarcoma is composed of both epithelial and non-epithelial elements, does the presence of a purely epithelial tumor in the contralateral ovary indicate these are separate primaries per rule M8? |
For cases diagnosed 2007 or later, accession two primaries, carcinosarcoma [8980/3] of the left ovary and serous carcinoma [8441/3] of the right ovary. 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). After determining the histology of each tumor (8980/3 and 8441/3), go to the Other Sites MP rules because ovary does not have site specific rules developed Start at the MULTIPLE TUMORS module, Rule M3. The rules are intended to be reviewed in consecutive order within a module. Stop at the first rule that applies to the case you are processing. Review Table 1 (Paired Organs and Sites with Laterality) to determine whether ovary is a paired site. To locate Table 1, go to Other Site under the Terms & Definitions section of the manual. Ovary is listed as a paired site. Accession multiple primaries when there are tumors on both sides (right and left) of a site listed in Table 1 (Paired Organs and Sites with Laterality). Carcinosarcoma [8980/3] is not an epithelial tumor of the ovary within the range of 8000-8799 and, therefore, Rule M7 does not apply. |

20120094 | Reportability: Given that per the 2012 SEER Manual and SINQ 20120081 VIN II-III is no longer reportable, does this change exclusively apply to VIN II-III or does it also apply to AIN II-III, VAIN II-III, etc.? See Discussion. |
VIN II-III was a reportable condition in the past. There was a SINQ note to that effect which is now gone from the system. Would it be better to reactivate that note and put a date reference in it so that there is documentation available to confirm this disease (and other IN II-III diseases) was previously reportable? If the note is not reactivated, could there be some indication in SINQ 20120081 of the prior reportability of this disease process? |
For cases diagnosed 2021 or later, VIN II-III is reportable. Similarly, AIN II-III, VAIN II-III, etc. are reportable. For cases diagnosed 2021 or later, the primary resource for reportability is ICD-O-3.2. Squamous intraepithelial neoplasia, grade II is listed in ICD-O-3.2 as 8077/2 making it reportable. This applies to the various sites of intraepithelial neoplasia grade II including anus, vulva, and vagina. |

20120088 | MP/H Rules/Multiple primaries--Head & Neck: How many primaries are accessioned and what rule applies if a patient has an extensive tumor in the left ethmoid sinus and a separate tumor in the right maxillary sinus? See Discussion. |
MRI and CT Neck Impression: Extensive tumor mass which likely originated within the left ethmoid sinus and extends intracranially via the cribriform plate into the anterior cranial fossa. There is involvement of the left orbit and extension into the superior aspect of the left maxillary sinuses as well as the nose. Second enhancing lesion within the right maxillary sinus measures almost 2 cm. The second mass within the floor of the right maxillary sinus, with similar imaging characteristics, is consistent with malignant involvement. The patient has an extensive ethmoid sinus tumor, biopsy showed squamous cell carcinoma. The ethmoid sinus is not a paired organ. The patient also has a small maxillary tumor with no histologic confirmation, Hem/Oncology chart notes state the right maxillary sinus mass is carcinoma. The maxillary sinus is a paired organ. Per the AJCC Manual (AJCC Manual for Staging, 7th edition, page 70), both the ethmoid and maxillary sinuses are further identified by their laterality (left and right). Why aren't the ethmoid sinuses a paired organ for the MP/H Rules? What MP rule applies to this case? |
For cases diagnosed 2007 or later, accession a single primary. 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 Head and Neck MP rules after determining the histology of each tumor - (8070/3 [squamous cell carcinoma] and 8010/3 [carcinoma, NOS]) because site specific rules have been developed for this primary. Start at the MULTIPLE TUMORS module, Rule M3. The rules are intended to be reviewed in consecutive order within a module. Abstract a single when one tumor is carcinoma, NOS [8010] and another tumor is a specific carcinoma, squamous cell carcinoma [8070] because the ethmoid sinus (site of origin) is not a paired site per the MP/H rules. We will review the list of paired organs for the next edition of the MP/H Rules. |

20120058 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be accessioned when the patient is diagnosed with an acute neoplasm (diffuse large B-cell lymphoma) per a pathology report and is subsequently diagnosed clinically with a chronic neoplasm (chronic lymphocytic leukemia/small lymphocytic lymphoma) less than 21 days later? See Discussion. | The patient was diagnosed with an extranodal DLBCL on a biopsy of the stomach. A bone marrow biopsy performed 16 days later showed no DLBCL, but demonstrated an abnormal CD5-positive B-cell population that was subsequently referred to as CLL/SLL by the physician. The peripheral blood was negative and showed only moderate thrombocytopenia.
Does rule M10 apply in this case? Abstract the acute neoplasm as a single primary (DLBCL) as there was only one pathology specimen (stomach biopsy) proving DLBCL and the bone marrow did not definitively identify CLL/SLL. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case should be accessioned as two primaries per Rule M11. Code the histology of one primary to 9680/3 [diffuse large B-cell lymphoma], the acute neoplasm. Code the histology for the second primary to 9823/3 [chronic lymphocytic leukemia/small lymphocytic lymphoma], the chronic neoplasm.
Per Rule M11, abstract as multiple primaries when both a chronic and acute neoplasm are diagnosed simultaneously or less than or equal to 21 days apart AND there is documentation of two pathology specimens, one confirming the chronic neoplasm (bone marrow biopsy) and one confirming the acute neoplasm (stomach biopsy).
