20021121 | Multiple Primaries (Pre-2007)--Kidney: How many primaries are reportable in a patient treated with a bilateral nephrectomy that revealed multiple tumors within each kidney and the histology in both the left and the right kidney was "renal cell carcinoma, indeterminate type: multiple histologically identical tumors" and the clinical discharge diagnosis was "bilateral renal cell carcinoma, probably surgically cured"? See discussion. | The SEER manual states "If only one histologic type is reported and if both sides of a paired site are involved within two months of diagnosis, a determination must be made as to whether the patient has one or two independent primaries." Frequently, the only statement we have is that "bilateral organs are involved." Additional guidelines for determining number of primaries would be helpful. | For tumors diagnosed prior to 2007:
Report this case as two primaries, left and right kidneys. According to our pathologist consultant, "The description sounds like bilateral multiple primaries. Multicentricity in the same kidney occurs in about 4% of all cases, and bilaterality in 0.5 to 3% (Atlas of Tumor Pathology, Tumors of the Kidney, Bladder, and Related Urinary Structures)."
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules. |

20021012 | EOD-Extension--Lymphoma: How do you code stage and EOD for an extranodal lymphoma with bilateral involvement of a paired site? See discussion. |
For example, we frequently see cases of lymphoma occurring in bilateral orbits, or both lungs. This issue was discussed at a 1991 SEER meeting with the tentative answer being that lymphoma involving both organs of a paired site will be coded as stage I (e.g., both eyes or both lungs), as this would be contiguous disease. However, an extranodal lymphoma involving tissue of both limbs (e.g., soft tissue of both arms) will be coded as stage IV because this represents wide areas of involvement that have no connection. | For cases diagnosed 1998-2003:
Bilateral involvement of an extralymphatic paired organ is coded as involvement of a single extralymphatic organ or site for lymphomas. The EOD extension code would be at least 11 (Stage IE). Staging lymphomas of any site depends on whether one or more lymph node regions and/or extralymphatic organs are involved, and whether sites on one or both sides of the diaphragm are involved. |

20021173 | Histology (Pre-2007): What code is used to represent a review of slides histology of "in situ squamous cell carcinoma and multiple detached fragments of atypical papillary squamous epithelium; highly suspicious for invasive carcinoma"? See discussion. | The original pathologist indicated a final diagnosis of moderately differentiated squamous cell carcinoma. The slides were sent for review to another facility. The reviewing pathologist rendered the diagnosis stated in the question section. | For tumors diagnosed prior to 2007:
Code the Histology field to 8070 [squamous cell carcinoma].
The review diagnosis was also squamous cell carcinoma. The expression "atypical papillary squamous epithelium" does not modify the cancer histology.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules. |

20021185 | Surgery of Primary Site--Major salivary gland: How do you code Surgery of Primary Site for a submandibular gland primary when the operative report refers only to an excision of the submandibular "tumor" while the pathology report states the submandibular "gland" was removed? See discussion. | The gross description on the pathology report indicates that the specimen consists of a "submandibular gland." A further description on the pathology report included, "the specimen was sectioned exposing a focally cystic mass that nearly replaces the entire specimen." | For cases diagnosed on 1/1/2003 or after: Code the Surgery of Primary Site field to 40 [Total parotidectomy, NOS; total removal of major salivary gland, NOS], per the pathology report's gross description of the specimen unless the operative report description of procedure indicates that the removal was less than total. | 2002 |
|
20021147 | Other Cancer Directed Therapy--Hematopoietic, NOS: Is "aspirin" treatment for primary polycythemia? See discussion. |
Aspirin is listed as treatment for "thrombocythemia" in the Abstracting and Coding Guide for the Hematopoietic Diseases but not for "primary polycythemia." |
Do not code aspirin as treatment for primary polycythemia (polycythemia vera). |

20021091 | Reportability--Hematopoietic, NOS: Are the terms "thrombocytosis, NOS" and "thrombocythemia, NOS" non-reportable to SEER? See discussion. |
Our understanding from SEER about how to classify these types of clinical impressions for the 2001 and later reportable blood diseases is as follows: If we cannot prove that it is malignant, then we should be conservative and exclude the case for reporting to SEER. |
For cases diagnosed prior to 1/1/2010:The terms "thrombocytosis, NOS" and "thrombocythemia, NOS" are not reportable to SEER. For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ. |

20020015 | Histology (Pre-2001): For cases diagnosed before 1/1/01, what code is used to represent the histology "small cell neuroendocrine carcinoma"? | For tumors diagnosed prior to 2001, code the Histology field to 8041/3 [small cell carcinoma] for "small cell neuroendocrine carcinoma". | 2002 | |
|
20021158 | Multiple Primaries/Histology--Lymphoma: What is the primary site(s) for a patient who had a lymph node biopsy with the histology of "large B cell lymphoma arising in the setting of low grade B cell lymphoma c/w marginal zone B cell lymphoma with plasmacytic features"? See discussion. | This patient also had a bone marrow biopsy that demonstrated "low grade B cell lymphoma." Per the clinician, "Pt with discordant lymphoma. We will be approaching his lymphoma as two different diseases. The large B cell had cleared after chemotherapy and radiation therapy. The low grade lymphoma is incurable." | For cases diagnosed prior to 1/1/2010: Code as two primaries with each arising in lymph nodes [C77._]. The histology for the first primary is 9699/3 [marginal zone B cell lymphoma]. The histology for the second primary is 9680/3 [large B cell lymphoma]. For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ. |

20021004 | Histology: What code is used to represent the histology for the abbreviation "ca"? See discussion. | The abbreviation "ca" results in inconsistency when coding histology by a group of coders. Many abbreviation guides list both cancer (8000/3) and carcinoma (8010/3) as definitions for "ca." Page 261 of the SEER Self Instructional Manual, Book 5 lists carcinoma as the definition for "ca."
Example: What histology is used for a case with a clinical diagnosis of "recently diagnosed uterine ca" with metastasis to the pelvic lymph nodes? |
For uterine primaries, code the abbreviation "ca" to 8010/3 [carcinoma, NOS].
When coding death certificate only (DCO) cases, if the site is coded to an unknown primary and no specific histology information is available other than the abbreviation "ca," interpret ca as cancer (8000/3) per NAACCR Procedure Guidelines for Registries, Series V; Resolving Death Clearance Issues, page V-15. |

20021150 | SEER Guidelines Over Time: Should we apply the current guidelines to previously missed older cases now being reported to the central registry? See discussion. | 1. We receive "straggler" cases for coding that were diagnosed when previous coding schemes and guidelines were applicable. When a specific guideline is in place for a given time period and is later changed in some way, we try to use the specific guideline that was in place at the time of diagnosis when coding the incoming case. However, it is not always possible to remember or to be able to access those old guidelines.
2. There are situations when coding old cases that have no applicable guideline for the older diagnosis years but current SEER documentation informs the coder how to handle the situation. For example, in the SEER Program Code Manual (3rd ed), 3 new guidelines were added for coding of differentiation. There were no guidelines in the previous SEER manual that specifically covered those situations. Should we use the current rules in coding differentiation on the older incoming case? |
Code all fields according to the instructions that were in effect at the time the case was diagnosed. If the old guidelines are unavailable or non-existent, code the case in the current scheme. The year the case was abstracted will indicate that the case was a late entry into the system and that could account for the differences in coding seen by a reviewer. | 2002 |
