20081105 | Primary site/Surgery of Primary Site--Lymphoma: What is the primary site for lymphoma involving lymph nodes and tonsil? Is a tonsillectomy coded as surgery for lymphoma? See Discussion. | 6/1/2008 cervical lymph node biopsy showed lymphoma. A 6/3/2008 CT Chest/abdomen showed mediastinal and mesenteric lymphadenopathy. A 6/15/2008 tonsillectomy is performed for markedly enlarged right tonsil. Tonsil pathology reveals extensive lymphoma involvement. Nothing in the chart specifies the primary site. Should this be a C778 primary because of 3 lymph node areas plus tonsil (a lymphatic organ)? Or should it be coded to C099 Tonsil? Is this tonsillectomy coded as surgical therapy? If so, is it surgery of primary site or surgery of other site? |
For cases diagnosed prior to 1/1/2010:Code the primary site to tonsil (C099). This advanced stage lymphoma involves an extranodal site (tonsil) and that site's regional lymph nodes (cervical). The lymphoma has also spread to non-regional lymph nodes (mediastinal and mesenteric). Code the tonsillectomy as surgery of primary site. For cases diagnosed 1/1/10 and later, 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. |

20081034 | Race, Ethnicity/Spanish Surname or Origin: Which Spanish Surname List (from 1980 census or 1990 census) would SEER prefer us to use to code 7 in Spanish Surname or Origin? See Discussion. | In the SEER coding manual, it refers to "a list of Hispanic/Spanish names" (5e), but does not specify which one to use. Again, for the Computed Ethnicity field, which Spanish Surname List does SEER prefer us to use? | Determine which list is better suited for your geographic area. If the 1990 list is used, determine the probability cut-off that seems most reasonable for your geographic area. | 2008 |

20081109 | MP/H Rules--Breast: Patient has 2 existing primaries, both of left breast and both were pure lobular carcinoma, one was diagnosed in 1994 and the other in 2005. Now a biopsy in 2008 of a supraclavicular lymph node (laterality unknown) and subcutaneous scalp tissue show metastatic DUCTAL carcinoma. Per path report, breast is the primary site. Slides from prior tumors were not reviewed. Should this be made a new primary or assumed to be metastasis from the prior breast tumors? See Discussion. |
A modified radical mastectomy was performed on 10/6/94. The 2007 MP/H rules tell us that multiple ductal and lobular tumors of breast are a single primary; however, the rules do not apply to metastatic tumors. |
For cases diagnosed 2007 or later: Abstract the 2008 diagnosis as a new primary. Since the primary site is unproven but stated to be breast, and since the laterality is unknown, we cannot determine that the 2008 diagnosis is the same as the 2005 or the 1994 diagnosis. Revise this case accordingly if more information becomes available. |

20081082 | Histology--Head & Neck: How do you code histology for a myofibroblastic sarcoma of the soft tissue of the head and neck? | Assign code 8825/3 [Myofibroblastoma, malignant]. According to the WHO Classification of Soft Tissue Tumors, "Low grade myofibroblastic sarcoma represents a distinct atypical myofibroblastic tumor often with fibromatosis-like features and predilection for the head and neck." Also called myofibrosarcoma. | 2008 | |

20081066 | Multiplicity Counter/Type of Multiple Tumors--Breast: How should these fields be coded when path shows a 1.2 cm infiltrating carcinoma with lobular features and several foci of infiltrating lobular carcinoma [7 foci described as multifocal], 1 large focus, and numerous foci of LCIS and CIS with lobular and ductal features? Should we count the foci or separate tumor nodules, ignore them, or code unknown values for these fields? See Discussion. | Scenario: 10/17/07: Right axilla soft tissue bx - infiltrating mammary ca with lobular features arising within apparent breast tissue present within axilla. Tumor size 1.2 cm. 11/3/07: Right breast, reexcision lumpectomy - Several foci of infiltrating lobular CA. (2) foci & (5) foci within specimen (multifocal). (1) large focus also present. No lymphovascular invasion identified. Numerous foci LCIS. Pleomorphic LCIS & CIS with lobular and ductal features. Margins free of invasion however margins diffusely involved with LCIS.
When do you count foci or separate tumor nodules, when do you ignore them, and when do you code unknown values for these fields? Coding instruction 3b states, "When the tumor is multifocal or multicentric and the foci of tumor are not measured, code as 99." Instruction 4b states, "Use code 01 when there is a single tumor with separate foci of tumor." Finally, instruction 6b states, "Use code 99 when the tumor is described as multifocal or multicentric and the number of tumors is not given," which seems to imply that if we know the number of tumors, we would code that number. |
Multiplicity Counter: Use instruction 4b. Since there is one measured tumor and the foci were not measured, code the multiplicity counter 01 [One tumor only]. Type of Multiple Tumors: Code Type of multiple tumors 00 [Single tumor]. |

20081085 | MP/H Rules/Histology--Colon: Per MP/H rule H3 for colon, code 8144/3 [Adenocarcinoma, intestinal type] should not be used with C180-C189 [colon]. However, page 58 of the ICD-O-3 SEER Site/Histology Validation list of February 9, 2001 lists code 8144/3 as a valid histology for large intestine. See Discussion. | None of the errata have this site/histo combination. It is causing problems with researchers because pathologists still use the term: Adenocarcinoma, intestinal type for tumors of the large bowel. Please clarify or print errata. | For cases diagnosed 2007 or later: This issue has been presented to the Edits work group. The preliminary response is that 8144/3 will be removed from the valid site/histology list for large intestine, small intestine, and rectum. The edits based on the site/type list are used by many organizations. Any change to the site/type list is taken to the Edits work group. |

20081139 | Date Multiple Tumors--Prostate: For a prostate biopsy done 10/20/08, both lobes involved with tumor, unknown how many tumors, what would be coded in date of multiple tumors? | In this case, code the date of the biopsy in Date of Multiple Tumors [10202008]. When the number of tumors is unknown, code the date of diagnosis as the Date of Multiple Tumors. This is the date on which it was determined that there were an unknown number of tumors. This instruction will be added to next edition of the MP/H manual. | 2008 | |
|
20081004 | First course treatment/Histology--Lymphoma: What treatment, if any, is coded for a patient with methotrexate induced lymphoma when the treatment plan is to take the patient off methotrexate? Also, is there a specific histology for drug induced lymphoma? See Discussion. | Diffuse Large B-cell Lymphoma of soft palate & nasal septum, methotrexate induced, in 5/07. Patient was taken off methotrexate with complete resolution of disease. No other treatment was given. Patient was on methotrexate for treatment of rheumatoid arthritis. | For cases diagnosed prior to 1/1/2010:Treatment: Code the treatment fields to 00 [not done] in this case. Document the discontinuation of methotrexate for rheumatoid arthritis in a text field. Histology: Assign code 9680/36 [Malignant lymphoma, large B-cell, diffuse, NOS]. There is no specific histology code for therapy-related lymphoma. For cases diagnosed 1/1/10 and later, 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. |

20081060 | CS Tumor Size--Lung: If a 5/11/07 CT showed a 6.5 cm LLL mass and a 7/24/07 CT showed 8.4 cm LLL mass, do we code the larger tumor size identified within four months of diagnosis or do we code the first size documented at the time of diagnosis? | This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Code the larger tumor size. |

20081118 | Surgery of Primary Site--Brain and CNS: How is this field to be coded when a patient undergoes stereotactic biopsy of a brain tumor? Path specimen consists of four fragments of tissue measuring .7, .6 and .3 cm. | Assign code 20 [Local excision (biopsy) of lesion or mass. Specimen sent to pathology from surgical event 20]. | 2008 |
