20110029 | DCO/Multiplicity Counter/Type of Multiple Tumors: How are these fields coded for an unknown primary reported as a DCO case? See Discussion. | Do DCO cases have default values for the Multiplicity Counter and Multiple Tumor Reported as One Primary fields? Should these fields be coded as 88 or 99?
In the data item pages for these fields, there is only a reference to see the NAACCR Death Clearance Manual. However, this manual does not provide an answer. There is guidance to use code 88 for unknown primaries but we noticed that SEER edits skip enforcing this requirement for DCO cases (see SEER IF205 and 206). |
For a DCO case reported as an unknown primary [C809], code Multiplicity Counter to 99 [Unknown if multiple tumors; not documented] and Type of Multiple Tumors Reported as One Primary to 99 [Unknown]. | 2011 |

20110093 | Residence at dx: After living elsewhere (Florida) and traveling around the country in an RV with his spouse, is a patient a resident of this area for either primary if he was diagnosed with his first primary less than a month after arriving in the area and a second primary more than a year after parking his RV here? |
Use the patient's usual residence to determine residency. If the usual residence is not known or the information is not available, use the residence the patient specifies at the time of diagnosis. The SEER rules for determining "usual residence" match the rules used by the US Census Bureau. |

20110132 | Reportability/Histology--Heme & Lymphoid Neoplasms: Is a diagnosis of "small B-cell non-Hodgkin lymphoproliferative disorder" reportable? If so, how is the histology to be coded? See Discussion. | The final diagnosis of a bone marrow biopsy dated 10/99/2010 was "small B-cell non-Hodgkin lymphoproliferative disorder." The differential diagnosis includes atypical small lymphocytic lymphoma/chronic lymphocytic leukemia and marginal zone lymphoma. Mantle cell lymphoma is very unlikely based on BCL1 negativity. Lymphoplasmacytic lymphoma is also excluded due to the absence of a plasma cell component (CD138 negative). | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Yes. The term "small B-cell non-Hodgkin lymphoproliferative disorder" is reportable. Code the histology to 9591/3 [non-Hodgkin lymphoma, NOS] per Rule PH28. When there is a diagnosis of lymphoproliferative disorder and any lymphoma, code the lymphoma histology.
The information in the discussion is reflective of the difficulty in diagnosing hematopoietic and lymphoid neoplasms. The differential diagnosis indicates that a number of possible specific lymphoma/leukemia diagnoses that have been ruled out, which explains why the final diagnosis is non-Hodgkin, NOS.

20110077 | MP/H Rules/Multiple primaries--Breast: How many primaries are to be reported if different recurrence scores are found on the Oncotype Dx studies performed for multiple tumors in the same breast if the clinician states the patient has two primaries but the pathologist does not address the issue? See Discussion. | A patient has two separate lesions in the same quadrant with the same histology. According to the MP/H rules this is a single primary. However, Oncotype Dx studies were performed on both tumors and the DX recurrence was different for each tumor. The medical oncologist states the patient has two primaries. The pathologist does not indicate the number of primaries. | This is a single primary. The only rules used to determine the number of primaries are the MP/H rules for cases diagnosed 2007 or later. Do not use other information such as Oncotype Dx to determine the number of primaries for a patient. Oncotype is used to determine whether the cancer is likely to recur AND whether the cancer would benefit from chemotherapy.
The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules manual. Once in the manual, locate the Breast MP rules under one of the three formats (i.e., flowchart, matrix or text).
Start with the MULTIPLE TUMORS module, Rule M4. The rules are intended to be reviewed in consecutive order within the module from Rule M4 to Rule M13. You stop at the first rule that applies to the case you are processing.
The patient has two tumors in the same breast with the same histology. Abstract a single primary for this patient. |

20110090 | MP/H Rules/Histology/Behavior--Ovary: How are these fields coded for a 20 cm borderline mucinous tumor with a 0.3 cm minor focus of intraepithelial carcinoma of the ovary that the pathologist stages as T1a? | According to the MP/H rules, code histology to 8010/2 [intraepithelial carcinoma] for cases diagnosed 2007-2014. Borderline mucinous tumor is not reportable to SEER.
The steps used to arrive at this decision are:
Go to the Other Sites Histo rules found in the Multiple Primary and Histology Coding Rules Manual.
Start at the SINGLE TUMOR: IN SITU ONLY module, rule H1. Code the histology when only one histologic type is identified. The only reportable histology in this case is intraepithelial carcinoma [8010/2]. |

20110137 | MP/H Rules/Histology--Skin: How is the histology coded for a "malignant baso-melanocytic tumor" arising in the skin of right shoulder? | Code the histology as melanoma, NOS [8720/3].
This is a malignant skin tumor with both melanoma and basal cell carcinoma histologies. There is no ICD-O-3 code for this entity. Per our subject matter expert, code the histology to 8720/3 [melanoma, NOS] and document the diagnosis of malignant baso-melanocytic tumor in a text field because melanoma is reportable to SEER and basal cell carcinoma is not.

20110020 | Heme & Lymphoid Neoplasms: How is cancer status to be coded when a patient diagnosed with MDS, undergoes treatment, but the MDS subsequently transforms to AML? | If the bone marrow no longer shows evidence of MDS, the cancer status for the MDS is disease-free. When cancer status is coded as disease-free (NED), it means that currently there is no clinical evidence of this disease (MDS). | 2011 | |

20110043 | MP/H Rules/Histology--Breast: Which specimen should be used to code histology when a core biopsy revealed an unknown sized DCIS, comedo type and the partial mastectomy specimen showed only a 2mm focus of DCIS, solid pattern? See Discussion. | Should the histology be coded from the needle core biopsy or the partial mastectomy specimen? Patient had a needle core biopsy that revealed DCIS, comedo type, cribriform pattern, no tumor size given. Subsequently, the patient had a partial mastectomy which revealed DCIS, noncomedo type, solid pattern, largest focus of DCIS was 0.2cm.
Should the histology code be 8501/2 or 8230/2? The microscopic description on the partial mastectomy says that the previous core needle biopsy site revealed several foci of DCIS. |
Code the histology from the most representative specimen (the specimen with the MOST tumor tissue). Compare the size of tumor in the two specimens. If the tumor size is not available for both procedural specimens, code histology from the mastectomy specimen rather than the needle biopsy specimen. | 2011 |

20110006 | Reportability--Heme & Lymphoid Neoplasms: Are all stages of CLL reportable? See Discussion. | If a physician notes the patient has Stage 0 CLL (increasing leukocytosis), is this reportable? CLL Stage is not mentioned in the Hematopoietic Manual or Database, but internet research reveals CLL has five stages (Stage 0, I, II, III, and IV). | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Yes. All stages of CLL are reportable. CLL has a unique staging system. The Heme DB and Manual do not address the issue of stage. Therefore, stage information is not reported in the Abstractor Notes section of the Heme DB.

20110038 | Reportability/Behavior: Is a "minimally invasive thymoma" a reportable malignancy if the pathology report does not specifically state it is malignant? See Discussion. |
For example, are Types A, B1, B2 and B3 reportable if the pathology report does not state the tumor is a "Malignant Thymoma"? |
For cases diagnosed prior to 2021 According to our expert pathologist consultant, code using the terms in the pathology report. Do not try to second guess the pathologist.
