20110147 | Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How is the histology coded when no bone marrow examination is performed but the peripheral blood flow cytometry listed several differential diagnoses and the physician states the diagnosis is small lymphocytic lymphoma? See Discussion. | The peripheral blood flow cytometry results state, "findings consistent with a small mature B-cell neoplasm, differential - marginal zone lymphoma, lymphoplasmacytic lymphoma, and atypical CLL." The physician states the diagnosis is "SLL." No bone marrow examination or CT scan was done to assess whether the patient had lymphadenopathy.
Per Rule PH5, if the diagnosis is B-cell CLL/SLL and peripheral blood is involved, the histology is coded to B-CLL/SLL [9823/3]. Should the primary site and histology be coded to bone marrow [C421] and CLL/SLL [9823/3] per Rule PH5 despite the physician's diagnosis of SLL [9670/3]? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This is a single primary and the primary site and histology is coded as bone marrow [C421] and CLL/SLL [9823/3]. The code 9670/3 [malignant lymphoma, small B lymphocytes, NOS] used for SLL is now obsolete.
Per the Abstractor Notes section in the Heme DB indicates that SLL is, "usually associated with CLL and coded CLL/SLL 9823/3. Small lymphocytic lymphoma (SLL) is almost identical to CLL. A somewhat arbitrary distinction is drawn between them based on the relative degree of marrow and nodal involvement and the numbers of circulating cells."
Per the Definition section in the Heme DB it states that, "CLL by definition involves blood and bone marrow at time of diagnosis." Check the PRIMARY SITE and MODULE RULE sections that indicate the primary site is C421, Rule PH5. Per this rule, code the primary site bone marrow (C421) and code the histology B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) [9823/3] when the diagnosis is B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) AND peripheral blood is involved (the bone marrow may also be involved).
This may appear to contradict the physician's diagnosis, but the 2008 WHO no longer codes CLL and SLL as separate neoplasms, rather one neoplasm, CLL/SLL, which reflects the actual neoplastic process. Those patients with SLL usually manifest CLL during the neoplastic process and those patients with CLL usually manifest SLL during the neoplastic process. WHO recommends coding to CLL/SLL rather than coding two primaries when the other neoplasm manifests.

20170072 | Reportability--Heme & Lymphoid Neoplasms: Is the diagnosis of large granular lymphocyte syndrome or large granular lymphocyte disorder a reportable synonym for T-cell large granular lymphocytic leukemia? See Discussion. |
The physician consult in this case further specifies that the large granular lymphocyte disorder represents an autoimmune disease of autoimmune T-cell mediated mechanism. Is this a reportable diagnosis? |
Report large granular lymphocyte disorder (9831/3). Alternate names for T-cell large granular lymphocytic leukemia (9831/3) listed in the Hematopoietic and Lymphoid Neoplasms Database include but are not limited to Chronic large granular lymphocyte lymphoproliferative disorder, large granular lymphocytosis, NOS, and T-cell large granular lymphocytosis. |

20160036 | Reportability/Histology--Head and Neck: Is mammary analogue secretory carcinoma (MASC) of the left submandibular gland reportable and how is it coded? See Discussion. |
The physician is calling it an indolent tumor, pT3/NX/M0 stage 3 with positive margins. Is the correct code C509, 8502/3? |
Mammary analogue secretory carcinoma (MASC) is reportable. MASC is a recently described tumor that predominantly arises in the parotid gland. In this case, if the primary site is submandibular gland, assign C080. We contacted our expert pathologist and he stated that the best code to use for MASC is 8502/3. Override any edits triggered by the combination of C080 and 8502/3. |

20031072 | EOD-Pathologic Extension--Prostate: Is extracapsular extension implied by the phrase "tumor invades the fibrous tissue of the capsule"? See Description. |
The physician staged to a pathology stage of T3. It appears the physician regards the following pathology statement to be equivalent to capsular invasion on the right side: "Tumor invades the fibrous tissue of the capsule on the right side where it approaches to within 1 mm. of the surgical margin." Should pathologic extension be coded to 42[unilateral extracapsular extension]? |
Use the best information available to stage the case. In this case, the best information is the pathologist's description of the tumor extension rather than the AJCC stage. For cases diagnosed 1995-2003: Extracapsular extension is not implied by the phrase in the question. Code the capsular involvement described to 32 [invasion into but not beyond the prostatic capsule] on the basis of the pathology report. |

20210014 | Solid Tumor Rules (2018, 2021)/Multiple Primaries--Lung: How many primaries should be reported for a 4/2019 diagnosis of left upper lobe (LUL) adenosquamous carcinoma (left lingula mass biopsy: adenosquamous carcinoma; LUL lung biopsy: pulmonary adenocarcinoma, stated to be a collision tumor and single primary per the Tumor Board), treated with radiation followed by an enlarging LUL mass in 7/2020 found to be squamous cell carcinoma? See Discussion. |
The physician stated the prior LUL adenosquamous carcinoma was PD-L1 negative and the LUL squamous cell carcinoma is PD-L1 positive and is calling it a new primary. 5/22-7/3/19 6000x30 IMRT Photons LUL lung Chemo refused Not a Surg candidate 10/01/2019 CT Chest: IMP: In comparison to CT chest 03/06/2019 and PET/CT 03/21/2019, left lingular mass has mildly decreased in size. Left apical anterior and posterior lung lesions more anterior lesion appears slightly increased in size, the other slight decreased in size, with adjacent areas of atelectasis and scarring. 06/23/2020 CT Chest: MP: In comparison to CT chest 10/1/2019, left lingular mass has increased in size concerning for increasing tumor with adjacent thicker focal pleural thickening involving the chest wall, concerning for possible chest wall invasion. Left apical anterior and posterior lung lesions appears more solid in appearance, representing known adeno CA, given that the appearance has changed, is concerning for residual tumor. 07/06/2020 PET: Hypermetabolic lingular mass and peripheral nodularity has increased in size and FDG avidity on the prior PET/CT. Left apical nodular opacity is difficult to separate from fairly uniform mild left apical pleural hypermetabolism which may be treatment related and/or neoplastic. |
Abstract two primaries: 8560 and 8140 using rule M6. One of the original tumors with adenosquamous now shows only residual SCC following XRT. PD-L-1 is not used to determine multiple primaries. Assuming three tumors (the post-XRT SCC is not a new tumor but residual from one of the adenosquamous tumors) there are two primaries: 8560 and 8140 per M6. For collision tumors, each histology identified in the tumor is used to determine multiple primaries. |

20110150 | Ambiguous Terminology--Heme & Lymphoid Neoplasms: As ambiguous terminology is not used to code histology for Heme & Lymphoid primaries, how is the histology coded when a patient has a clinical diagnosis of "consistent with a myelodysplastic syndrome"? See Discussion. | The physician states the "patient's clinical picture certainly is most consistent with MDS." Several FISH probes were performed on peripheral blood, specifically looking for the 5q minus syndrome as well as other molecular rearrangements to suggest or confirm MDS. These studies came back as normal. The initial bone marrow also came back negative. The physician then states, "The suspicion was that this represented a myelodysplastic syndrome despite the normal cytogenetics. Additional studies performed on the date of the clinic visit included the FISH for the 5q minus syndrome as well as CD59 to exclude PNH. Both of these were negative. Therefore, at this juncture, the patient has a macrocytic anemia not yet requiring transfusion support with a normal white count and an elevated platelet count and a hypercellular bone marrow. This is certainly consistent with a myelodysplastic syndrome."
Per coding guidelines, ambiguous terminology is not used to code histology, only for reportability. What is the histology code for this case? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology as Myelodysplastic syndrome, unclassifiable [9989/3].
Ambiguous terminology is used to accession cases (determine reportability). While ambiguous terminology is generally not used to code a specific histology, it can be used to code histology if it is the .
The statement that you do not use ambiguous terms to code histology is intended for those NOS histologies with an ambiguous term being used to describe the subtype. For example, if the physician states this is a myelodysplastic syndrome, NOS, refractory thrombocytopenia. The correct histology would be MDS, NOS [9989/3] and not refractory thrombocytopenia [9992/3].

20190065 | Update to current manual/EOD 2018/Summary Stage 2018--CLL/SLL: Can chronic lymphocytic leukemia (CLL) be staged when diagnosed by peripheral blood and no bone marrow biopsy, and observation is employed? See Discussion. |
The physicians do not use the Lugano system as we are instructed to stage chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) as lymphomas. I had always been instructed that this qualifies as "bone marrow involvement," or "diffuse disease," and therefore is a Stage IV. Our experts advise that there is not enough information to code it to bone marrow, but do not elaborate as to whether you can actually code Extent of Disease (EOD), SEER Summary Stage, and AJCC Staging? |
For EOD and Summary Stage: Peripheral blood involvement for CLL (or any lymphoma-but most commonly for CLL) can be coded. This is code 800 for 2018 EOD Primary Tumor, and code 7 for Summary Stage 2018. We have recently received confirmation that peripheral blood involvement only is not enough information to assign AJCC stage; assign code 99 for AJCC Stage Group. We will correct in the 2021 release of EOD so that peripheral blood involvement only will have its own code to derive the appropriate AJCC TNM Stage Group (99). |

20180061 | Primary Site: How should primary site be coded when there is an invasive tumor in one subsite and an in situ tumor in another subsite of the breast? See Discussion. |
The previous SEER Program Coding and Staging Manual included Appendix C that has Coding Guidelines for some sites. The breast guidelines specifically instructed one to code the subsite with the invasive tumor when the pathology report identifies invasive tumor in one subsite and in situ tumor in a different subsite or subsites. The current Breast Solid Tumor Rules Table 1: Primary Site Codes refers one back to the SEER Manual and COC Manual for a source document priority list but does not make mention of invasive vs. in situ on that final version of the source document. In addition, the Colon Solid Tumor Rules currently contains no Site Coding Section/Table. However, the Lung Solid Tumor Rules do and also refer one to the SEER/COC Manuals for document priority lists. The Urinary Solid Tumor Rules has both the Primary Site Codes Table and an additional section called Priority for Coding Primary Site, which does not reference a document priority list or other manuals. Unfortunately, there is additional information in Appendix C Bladder Coding Guidelines that may have been used in the past regarding site source priority. Could the remaining applicable Appendix C information be consolidated into the Solid Tumor Rules consistently among all the sites to lessen the need for additional manual referencing? Also, is there a reason one site includes the Priority Site Coding instructions and others do not? |
Code the subsite with the invasive tumor as the primary site when the pathology report identifies invasive tumor in one subsite and in situ tumor in a different subsite or subsites as stated in Appendix C, Breast Coding Guidelines, 2018 SEER Program Coding and Staging Manual. This statement is unchanged from the previous version; however, the priority list was modified for coding a subsite when there is conflicting information. The focus of the Solid Tumor Rules is to differentiate between single vs. multiple primaries and to assist with identifying the appropriate histology code. The site tables in the solid tumor rules are a reference only. The site-specific Coding Guidelines assist with additional considerations when abstracting cases. |

20010143 | EOD-Lymph Nodes/EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined--Lung: How do you code these fields for clinically positive lymph nodes when the result of neoadjuvant treatment is that the lymph nodes are pathologically negative? See discussion. | The pt presents with "mediastinal adenopathy" for a lung primary and was treated with pre-operative radiation therapy. After two months, he was treated with surgery. The 10 lymph nodes removed were all negative. How does SEER code these three EOD fields?
Will an error be triggered in SEER Edits if you code lymph nodes as clinically positive in the EOD lymph node involvement field and yet pathologically negative in the number of regional nodes positive and number of regional nodes examined fields? |
For cases diagnosed 1998-2003:
Code the EOD-Lymph Nodes field to 2 [Mediastinal, NOS]. Code the EOD-Regional Lymph Nodes Positive and Examined fields to 00/10. You will not have a problem with the SEER Edits. The EOD field is coded using clinical and pathologic information. All information gathered within four months of the date of diagnosis (in the absence of disease progression) or through completion of surgery(ies) can be used to code EOD. The clinically positive nodes justify the radiation therapy. |

20240039 | Update to Current Manual/Race: For the Example #15 under Race Coding Examples in the 2024 SEER manual, could coding these as 97 result in an under-reporting of Native Hawaiians? See Discussion. |
The race category in some hospital electronic medical record systems includes a combined category of “Native Hawaiian/Pacific Islander.” What race code should be used in a situation where the only available information is “Native Hawaiian/Pacific Islander?” |
Change to current instructions. We will update this example in the next edition of the manual. The new example will instruct registrars to look for other descriptions of the patient’s race. When no other information is available, assign 07, Native Hawaiian, in Race 1 and assign 97, Pacific Islander, NOS in Race 2. Begin following this new instruction now. |
