20091043 | Multiple primaries--Lymphoma: Should a second primary lymphoma be accessioned if the reporting hospital disagrees with the final diagnosis stated on a review of slides? See Discussion. |
Example: Patient had an original diagnosis of small lymphocytic lymphoma (9670/3) of lung in 1986 and later presents with small B-cell non-Hodgkin lymphoma (9670/3) of small bowel in 2008 at Hospital A. Slides sent for review at Hospital B where patient was also seen. Slides there read as low grade B-cell lymphoma most consistent with extranodal marginal B-cell lymphoma of mucosal associated tissue (MALT Lymphoma). Hospital A's pathology report stated that immunostains would exclude mantle cell lymphoma and MALT lymphoma and the original pathology report has not been amended to match the outside path diagnosis. Is thisĀ a second primary of MALT lymphoma (9699)? |
For cases diagnosed prior to 1/1/2010:The 2008 diagnosis is not a new primary according to the Definitions of Single and Subsequent Primaries for Hematologic Malignancies (the tri-fold heme table) using the pathology report diagnosis from the facility where the procedure was performed (Hospital A). Since Hospital A disagreed with the slide review and did not amend their diagnosis based on the slide review, do not use the slide review diagnosis in this case. 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. |

20091116 | MP/H Rules/Multiple primaries - - Colon: Is a colon tumor reported as "recurrent at the anastomotic junction" just over one year after the diagnosis of a T4 colon tumor to be counted as a new primary? See Discussion. | MP/H rules do not apply to metastasis. However, it has been our experience that pathologists and clinicians tend to use the terms metastatic and recurrence interchangeably. The term "recurrence" is not limited to a tumor recurrence in the same site as a previous malignancy. Sometimes it is obvious that the clinician is using the term recurrence to describe a metastatic lesion. When a "recurrence" is located in tissue that is very different from the original primary site, it is easy to recognize that the intended meaning of the term is metastasis.
Example: Patient with squamous cell carcinoma of the tongue with recurrence in the lung.
However, when the metastatic deposit occurs in similar tissue, it is more difficult to determine the number of primaries.
Example when the term "recurrence" is ambiguous: In April 2008 patient was diagnosed with adenocarcinoma of the ascending colon. At the time of hemicolectomy the tumor was noted to be plastered into the paraduodenal and peripancreatic area. Patient received one dose of adjuvant chemo and then discontinued treatment. In May 2009 the patient was found to have adenocarcinoma in the transverse colon. Per the pathology report the diagnosis for segmental resection at that time showed colonic adenocarcinoma. Tumor location: tumor appears recurrent at anastomotic junction. Abdominal wall mass showed metastatic adenocarcinoma.
One has to wonder if the pathologist found a metastatic nodule at the anastomotic site and called it "recurrent." It is unlikely that the pathologist will compare this specimen to the previous tumor, having already diagnosed it as "recurrent."
|
For cases diagnosed 2007 or later, Rule M4 applies to the example of adenocarcinoma of ascending colon diagnosed in 2008 followed by adenocarcinoma of transverse colon diagnosed in 2009. When a colon resection has taken place, the original primary site is no longer present. A colon resection usually includes a portion of uninvolved colon on either side of the tumor. A tumor diagnosed at the anastomotic junction cannot be located in the same site as the previous tumor. Use of the term "recurrent" in this case is not synonymous with "metastatic." Apply the MP/H rules. | 2009 |

20081094 | CS Lymph Nodes--Breast: Now that code 50 [fixed/matted ipsilateral axillary LNS, NOS] is obsolete, how is this field coded for a case in which there are clinically matted lymph nodes, no neoadjuvant therapy, and no lymph node size on the available pathology report? | 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.From the American College of Surgeons: The pathologic information always takes precedence over the clinical information when there is no neoadjuvant therapy. The size reference is that this is not ITC or micromets. Clinically, I don't think you can have fixed or matted nodes that aren't greater than micromets. This would be coded to 52. The mapping for all of these codes is not taken from this, but from the value of SSF3 per the note at the bottom of the table. See CS Lymph Nodes note 2. |

20081054 | First course treatment: Is subsequent treatment with R-ICE first course or second course therapy if the patient underwent ABVD x2 cycles and subsequent imaging showed no response to treatment and evidence of progression [new adenopathy] for a lymphoma case? See Discussion. |
Patient was initially diagnosed with Hodgkin Lymphoma, Nodular Sclerosing on 3/3/06. Patient received ABVD x 2 cycles. Had disease reassessed in May, 2006, no response to treatment, showed evidence of progression (new adenopathy). Patient's pathology from 3/06 was sent for consult: Diagnosis was Hodgkin with some overlapping features of B-cell Non Hodgkin Lymphoma. Treated 5/18/06 with R-ICE FOR NHL. |
The R-ICE treatment in this case is not part of the first course. Documentation of treatment failure and/or disease progression signifies the end of the first course of treatment. |

20081044 | MP/H Rules/Behavior--Melanoma of Skin: How are histology and behavior coded for a "malignant melanoma in situ with regression"? See Discussion. | Per the microscopic portion of the path report, there is a zone of regression within the confines of the lesion, such that the possibility of antecedent invasive disease at the site cannot be ruled out with certainty. | For cases diagnosed 2007 or later: Code malignant melanoma in situ with regression to 8720/2 [Melanoma in situ]. Code the histology according to the histologic type specified in the pathology report final diagnosis. Code the behavior as specified in the pathology report. Regression does not affect the coding of histology or behavior. See Melanoma Histology Coding rule H5. See 2007 SEER manual instructions for coding behavior, page 84. |

20081111 | MP/H Rules/Histology--Breast: If an in situ carcinoma diagnosed in 2007 demonstrates comedo necrosis, should the histology be coded to comedocarcinoma in situ? See Discussion. |
According to the new MP/H rules, we code descriptive features. There is no coding guidance or reference to "necrosis" within the breast MP/H rules. Based on SEER SINQ 20021002, the "comedo necrosis" would not be coded at all for pre-2007 cases. Does this still hold true for cases diagnosed after January 1, 2007? |
For cases diagnosed 2007 or later, comedo necrosis is not synonymous with comedocarcinoma. If no further information is available for this case, code as carcinoma in situ. |

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 |
|
20081130 | MP/H Rules--Breast: What histology code is used for lobular with focal ductal features? Do we ignore the focal features and code as lobular or do we use the combination code for duct and lobular? | For cases diagnosed 2007 or later, use rule H14 and assign code 8520 [lobular]. Ignore histologies described as "focal," "foci," or "focus." This instruction will be added to the next version of the MP/H manual. | 2008 | |
|
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 | |
|
20081124 | CS Extension--Brain and CNS: How is CS Extension coded for a malignant meningioma that demonstrates extension into adjacent brain tissue? For malignant brain tumors, code 60 represents extension into the meninges. Would code 60 be the correct code for extension from a malignant meningioma into brain tissue? |
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.Assign CS extension code 60 for malignant meningioma with extension to adjacent brain tissue. According to the I&R, this section of CS was taken directly from SEER Summary Staging, since AJCC does not have a staging system for these tumors. |
