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).

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. |

20120019 | Surgery of Primary Site/Scope Regional LN Surgery--Breast: How are these fields coded for breast cases diagnosed 2011 and later when the patient has a simple mastectomy with removal of seven sentinel lymph nodes? See Discussion. | Per SINQ 20091076, the correct codes would be 41 [simple mastectomy] and 2 [sentinel lymph node biopsy only] when the patient has any number of sentinel nodes removed, as long as they are designated as sentinel nodes. Under the mastectomy codes in the 2011 SEER Manual, Appendix C, Breast Surgery Codes, the SEER Note states that code 41 [simple mastectomy] includes the removal of one to three axillary lymph nodes. A simple mastectomy with four or more axillary lymph nodes is coded to 51. Does the lymph node count for code 51 include both sentinel and axillary lymph nodes? Or does code 51 refer to strictly the count of axillary lymph nodes, separate from the count of sentinel lymph node(s) biopsied? | First, make sure that the seven lymph nodes removed were actually designated to be sentinel nodes and not a combination of sentinel nodes and other regional nodes. Code sentinel nodes only when the nodes are stated to be sentinel nodes or when the surgical procedure includes the injection of dye to identify sentinel nodes. If all seven nodes removed are sentinel nodes, follow the instructions in SINQ 20091076 and assign codes 41 [simple mastectomy] and 2 [sentinel lymph node biopsy only]. The SEER Note does not pertain to nodes designated as sentinel nodes. |

20120009 | Histology--Heme & Lymphoid Neoplasms: How is the histology coded when the pathology report states the morphologic features and immunophenotype of a low grade B-cell lymphoma are most compatible with lymphoplasmacytic lymphoma or marginal zone lymphoma? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9591/3 [B-cell lymphoma, NOS] per Rule PH28 which states that one is to code the histology when the diagnosis is
There is only one non-specific histology code mentioned, low grade B-cell lymphoma. This term is synonymous with B-cell lymphoma, NOS.
Per the Multiple Primaries Calculator, when comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9671/3 [lymphoplasmacytic lymphoma], it is the same primary. When comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9699/3 [marginal zone lymphoma], it is the same primary.

20120033 | Multiple Primaries--Hematopoietic: How many primaries are abstracted when a patient is diagnosed with essential thrombocythemia in 2007 and a bone marrow biopsy performed on 12/4/2009 shows primary myelofibrosis? See Discussion. |
The patient was diagnosed with essential thrombocythemia in 2007 and was treated with Hydrea. The 2009 bone marrow biopsy showed primary myelofibrosis which the physician states is a transition from the essential thrombocythemia. The Heme DB calls this two primaries. |
This is a single primary, essential thrombocythemia [9962/3] diagnosed in 2007. The 2010 Heme DB and Manual should not have been used to determine the number of primaries in this case. The Heme DB applies only to cases diagnosed 2010 and later. In order to determine the number of primaries, use the rules in place at the time of the subsequent 2009 diagnosis of primary myelofibrosis. Per the Single Versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table, a diagnosis of essential thrombocythemia [9962/3] followed by a diagnosis of primary myelofibrosis [9961/3] is a single primary. |

20120042 | Histology--Heme & Lymphoid Neoplasms: How is the histology coded if a pelvic mass biopsy is positive for B-cell non-Hodgkin lymphoma and a mediastinal lymph node biopsy is positive for follicular lymphoma, grade 1? See Discussion. | CT guided core biopsy of pelvic mass is positive for B-cell non-Hodgkin lymphoma. Bone marrow biopsy is negative. Mediastinoscopy with mediastinal and pretracheal nodes biopsy is positive for follicular lymphoma grade 1 of 2. The patient has a PET demonstrating positive extensive metastatic disease with nodes in neck, chest, abdomen/pelvis and bone involvement. Should the histology be coded 9591/3 [NHL, NOS] or 9695/3 [FL, grade 1]? Which rule applies?
The table of contents for the Hematopoietic Manual indicates Module 8 for these histologies, however, Module 8 rules do not seem to apply. Continuing on to Module 9, the first rule that applies is PH30. PH30 states use the Heme DB to determine primary site/histology. The Heme DB indicates these are separate primaries, but both histologies are B-cell lymphomas. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9695/3 [follicular lymphoma, grade 1] per PH29.
Under the Alternate Names section of the Heme DB, B-cell non-Hodgkin lymphoma is synonym for non-Hodgkin lymphoma, NOS and B-cell lymphoma, NOS.
Per PH29, one codes the histology when there is one non-specific histology (NHL, NOS) and one specific histology (FL, grade 1). You are also required to confirm the specific and the non-specific (NOS) histology represent the same primary using the Multiple Primaries Calculator. The calculator indicates these are the same primary.

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. |

20120079 | Reportability: Is positive urine cytology (ex: malignant cells interpreted as carcinoma) by itself reportable? If so, is the case coded to bladder by default or is is coded to C689, urinary system, NOS? | Urine cytology positive for malignancy is reportable. Code the primary site to C689 in the absence of any other information.
However, if a subsequent biopsy of a urinary site is negative, do not report the case.
For 2013 diagnoses and forward, report these cases when they are encountered. Do not implement new/additional casefinding methods to capture these cases. As always, do not report cytology cases with ambiguous terminology. |

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. |

20120008 | MP/H Rules/Recurrence--Ovary: How many primaries are accessioned if a patient was diagnosed with ovarian serous carcinoma four years ago and currently has sacral and pelvic masses positive for serous carcinoma on biopsy? Should this be disease progression or a new primary? See Discussion. |
Should this be a new primary per the MP/H Rules (Other Sites, Rule M10) because the diagnoses were made more than one year apart? Or is the new disease metastasis? The pathologist did not compare the subsequent mass biopsies with the original pathology. Is a pathologist's comparison of slides the only criteria for determining recurrent disease? This case seems to fit the definition of metastatic disease rather than a recurrence, and therefore would not be a new primary. |
Accession a single primary, the original ovarian serous carcinoma. The MP/H Rules do not apply to metastases. Metastases: When cancer cells appear in other nodes or organs that are not the primary site they are metastatic cells. Discontinuous (separate from the primary tumor) masses or cells in regional lymph nodes, distant lymph nodes, or distant sites are always metastases. In this case, the sacral and pelvic masses are distant metastases. The pathologist does not have to compare cells to the original tumor slides; the discontinuous tumor mass/cells in any site other than the primary site are metastases. Recurrence: For a disease to recur there are several criteria that must be met. First and most important, the patient must have had a disease-free interval (a tumor cannot recur if it has always been present). The other criteria are: the "new tumor" has to occur in the original primary site, it must be the same histology as the original tumor, AND must meet the timing requirements in the MPH rules for that organ/site. |
