20100064 | Histology--Heme & Lymphoid Neoplasms: How is histology to be coded for acute lymphoblastic leukemia (ALL) and/or precursor B acute lymphoblastic leukemia (Pre-B ALL) for cases diagnosed 2010 and later? The Heme Database has two histology codes for this disease, both 9811/3 and 9836/3, which is the correct histology code? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code histology to 9811/3 [B lymphoblastic leukemia/lymphoma, NOS].
See the Abstractor Notes section in the Heme DB, when determining how to code histology for a case. It indicates the code 9811/3 is effective for cases diagnosed 2010 and forward. The 9836/3 is listed as obsolete and refers you to code 9811/3. Make sure to check for a specific subtype of B lymphoblastic leukemia/lymphoma [9812/3 - 9818/3] before assigning the NOS code [9811/3].

20100109 | Reportability--Ovary: Does the ICD-O-3 term "stromal endometriosis" [8931/3] always imply a reportable malignant disease process if the pathologist also states there is "no evidence of carcinoma" in the same report? See Discussion. | ROS Final Diagnosis: LSO: Ovary with an endometriotic cyst (1.2 cm) and stromal endometriosis with multifocal papillary syncytial eosinophilic, clear cell and tubal metaplasia, no evidence of carcinoma.
COMMENT: There is extensive endometriosis involving the ovarian stroma and the ovarian surface. The ovarian stroma contains multiple cystic endometrial glands and surrounding endometrial type stroma with variable amounts of hemorrhage. There are non-cystic foci of endometriosis comprised of small, irregular glandular structures within the stroma. The lining of larger cyst/cysts is involved by a single layer of cuboidal to columnar cells with markedly eosinophilic cytoplasm in areas of serous (tubal) metaplasia and papillary projections suggestive of papillary syncytial metaplasia. Within these areas there is epithelial tufting and stratification, raising the consideration of proliferative/borderline change (which we cannot entirely exclude), however, given the background of endometriosis and morphologic similarity to papillary syncytial metaplasia in the endometrium, we favor that this is a non-neoplastic reactive change. There is no evidence of carcinoma. |
This case is not reportable. The pathologist states that there is no evidence of carcinoma. The ICD-O-3 matrix system applies, giving the pathologist the final say on behavior. | 2010 |

20100087 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned for one patient with history of marginal zone lymphoma initially diagnosed in 1994, followed by a 2010 diagnosis of large B-cell lymphoma and another patient with both B-cell chronic lymphocytic leukemia/small cell lymphoma (CLL/SLL) and diffuse large B-cell (DLBCL) in 2009? See Discussion. | Case 1 - Patient has a history of marginal zone lymphoma diagnosed in 1994 with recurrences in 2007 and 2009. The patient now presents for a bone marrow biopsy in May 2010 and is found to have large B-cell lymphoma, transformation. The first primary, marginal zone lymphoma, falls under the 2009 rules and the second primary, large B-cell lymphoma, falls under the 2010 and forward rules?
Case 2 - Patient was diagnosed with B-cell CLL/SLL and a DLBCL in 2009. If the 2009 rules only apply, these are a single primary. If the patient is admitted and treated in 2010 are the rules still based on the diagnosis date? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Case 1: Accession two primaries per Rule M10 when a neoplasm is originally diagnosed as a chronic neoplasm AND there is a second diagnosis of an acute neoplasm more than 21 days after the chronic diagnosis. The histology for the first primary is 9699/3 [marginal zone lymphoma] represents a chronic neoplasm and the second primary is 9680/3 [diffuse large B-cell lymphoma] is an acute neoplasm which was diagnosed more than 21 days after the first primary.
Case 2: Do not use the Heme DB and Manual rules for this case. Both diagnoses were made prior to 2010. The Heme DB and Manual are only effective for cases diagnosed 1/1/2010 and forward. Use the ICD-O-3 Hematopoietic Primaries Table to determine the number of primaries for this case. Per the Table, a second diagnosis of DLBCL [9680/3] following a diagnosis of CLL/SLL [9823/3] is one primary.

20100011 | Reportability: Should a benign gangliocytic paraganglioma [8683/0] be a reportable (malignant) tumor based on the presence of lymph node metastases? See Discussion. |
"Resection, periampullary duodenum: Gangliocytic paraganglioma, with metastasis to one large periduodunal lymph node. Six other small lymph nodes negative. COMMENT: The primary tumor in the duodenum is made up mainly endocrine cell component. This component appears to have metastasized to a periduodenal lymph node." |
This neoplasm is reportable because it is malignant as proven by the lymph node metastases. Code the behavior as malignant (/3) when there are lymph node metastases. |

20100015 | Type of Multiple Tumors/Multiplicity Counter--Breast. Are the data items "Type of Multiple Tumors Reported as One Primary" and "Multiplicity Counter" related? How should they be coded for breast cases in which there are multiple measured invasive tumors, plus DCIS which is not measured nor stated whether it is separate from the invasive tumors? See Discussion.
|
For example, path report states only "multifocal invasive ductal carcinoma, 1.5 cm and 0.8 cm, and low-grade DCIS." The Multiplicity Counter instructions tell us to ignore/do not count foci that are not measured. Should we interpret this to mean, count only the two invasive foci and ignore the DCIS? Should Type of Multiple Tumors then be coded 30 or 40, because only the invasive tumors are coded in Multiplicity Counter? | Code Type of Multiple Tumors 30 [in situ and invasive]. The code in Type of Multiple Tumors may or may not reflect the tumors that were counted in Multiplicity Counter. For this case, it is correct to code 02 in multiplicity counter. | 2010 |
|
|
20100026 | Multiplicity Counter--Kidney, Renal Pelvis: How many times is this field updated after an invasive primary is originally diagnosed? Should subsequently diagnosed in situ tumors to be included in this field? See Discussion. | How should the Multiplicity Counter be coded when a patient has a renal pelvis primary [C659] diagnosed 1/23/08. The patient had one tumor, invasive grade 3 of 3 papillary urothelial carcinoma arising in the depth of a calyx in mid portion of kidney. In 6/1/09, a TURBT showed three separate high grade urothelial carcinoma in-situ lesions on the right side of the bladder, the largest tumor being 7mm. In 2/8/10, another TURBT showed one lesion on the left side of bladder, high grade urothelial carcinoma in-situ, tumor was 4mm. These are all a single primary per rule M8. | Code multiplicity counter 04. Count both invasive and in situ tumors.
Multiplicity counter would have been coded 01 in 2008. Add the three in situ tumors diagnosed in 2009 to the first tumor and update multiplicity counter to 04. Make only one update to multiplicity counter. Because the multiplicity counter was updated once, the fifth tumor diagnosed in 2010 does not need to be added. |

20100061 | MP/H Rules/Histology: The 2010 SEER Manual has omitted some useful information in the Histologic Type ICD-O-3 section, specifically the statement of "Do not revise or update the histology code based on subsequent recurrence(s)". Will this statement be added to the revisions of the MPH rules? See Discussion. | Example: A 2005 diagnosis of left breast lobular carcinoma [8520/3], followed by a 2009 diagnosis of left breast ductal carcinoma [8500/3]. Rule M10 states this is a single primary, but there is no information in the Histology rules (Multiple Tumors Abstracted as a Single Primary) that the original histology should be retained, thus a person could potentially use these rules to change the original histology to 8522/3 [duct and lobular carcinoma] per rule H28. | We will reinstate the instruction not to change the histology code based on recurrence in future versions of the histology coding instructions. However, this instruction may not be applicable to all anatomic sites. It will be reinstated on a site-by-site basis. You may also refer to the instructions on Page 7 of the 2010 SEER Manual under the heading "Changing Information on the Abstract." | 2010 |

20100054 | MP/H Rules/Multiple primaries--Breast: How many primaries are accessioned if a pathology specimen reveals an infiltrating mammary carcinoma with mixed tubular and lobular features, 2.3 cm, low grade cribriform in situ ductal carcinoma, and Paget disease of the overlying skin with ulceration? See Discussion. | According to SINQ 20081134 the histology would be 8524 if this is one primary. | For cases diagnosed 2007 or later, this is a single primary.
In order to determine whether this case represents a single or multiple primary, you must first determine the correct histology code for the underlying tumor. Using rule H9, ignore the DCIS.
See Table 3 in the equivalent terms and definitions. Infiltrating lobular, tubular, and Paget are coded to a single histology code (8524/3). Our current multiple primary rules do not say infiltrating lobular and tubular and Paget are a single primary. This was an omission and will be corrected in a future revision. Thank you for bringing this omission to our attention. |

20100071 | Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How many primaries are accessioned for a patient diagnosed in February 2010 with a plasmacytoma of the frontal skull followed by a diagnosis of smoldering myeloma by bone marrow biopsy? See Discussion. | The patient had a diagnosis of solitary plasmacytoma of the right frontal skull in 2/2010 that was totally resected (the cranial specimen final diagnosis was plasmacytoma). The patient received radiation. While undergoing radiation, the patient was seen by a medical oncologist who did a bone marrow biopsy that revealed 10-15% plasma cells, and was called smoldering myeloma. Watchful waiting was recommended. In 8/2010, the patient had multiple lytic lesions and began systemic treatment.
Per rule M15 and the Multiple primary calculator, 9731/3 [plasmacytoma] and 9732/3 [smoldering myeloma] is accessioned as two primaries. When the manual states, "Use the Hematopoietic Database to determine the primary site and histology when PH1-PH29 do not apply," does this mean to use the calculator not the database itself? By the old rules this was one primary. Did this change for cases diagnosed 1/1/10 and later? Which M rule is the correct rule to apply? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
The smoldering myeloma is a second primary per Rule M10. Accession as multiple primaries because this case was originally diagnosed as a chronic neoplasm (plasmacytoma)phase and there was a second diagnosis of an acute neoplasm (multiple myeloma) more than 21 days after chronic diagnosis. See note 1 which indicates, "This is a change from previous rules." Note that the MP rules and the MP calculator in the Heme DB agree.
When the rules tell you to go to the DB to determine the histology and primary site, you use the DB information. (Don't forget to check the Abstractor Notes). The multiple primaries calculator is used to determine the number of primaries to abstract. Always use the M rules before using the MP calculator.

20100050 | Reportability--Colon: Would a carcinoid tumor, NOS, of the appendix with perineural or angiolymphatic invasion be reportable if there is no mention of malignancy in the pathology report? |
Carcinoid, NOS, of the appendix diagnosed in 2015 or later is reportable.
For cases diagnosed prior to 2015
Carcinoids of the appendix are reportable when they meet any of the following conditions.
Note that the implants/involvement must be designated as malignant. Many benign tumors will spawn implants that are also benign. If implants are benign, this is not a reportable tumor. |
