20041003 | EOD-Size of Tumor: How is this field coded when the only description is "greater then 10 cm?" | For cases diagnosed 1998-2003: When the only information available is a statement such as "Greater than 10 cm," code tumor size 101 [10.1 cm]. | 2004 | |
|
|
20041011 | EOD-Clinical Extension--Prostate: Should this field be coded to 15 [Tumor identified by needle biopsy for elevated PSA] or 30 [Localized, NOS] when the only information is from a biopsy positive pathology report that includes the clinical history of "PSA elevated, DRE negative," with no mention of an ultrasound being performed? | For cases diagnosed 1998-2003: For this scenario, assign code 15 if an ultrasound was not performed, performed and negative, or when it is unknown whether or not an ultrasound was performed. Assign code 30 only if an ultrasound was performed and there is no documentation stating that it was negative or positive. Please refer to the Prostate EOD Coding Guidelines for all of the instructions pertaining to the coding of prostate EOD. |

20041013 | Primary Site--Ovary/Peritoneum: Should this field be coded to ovary or peritoneum when the bulk of the tumor is in the peritoneum and there is only surface involvement of the ovary? | If it is not clear where the tumor originated, use the following criteria to distinguish ovarian primaries from peritoneal primaries. The primary site is probably ovarian, unless: --Ovaries have been previously removed --Ovaries are not involved (negative) --Ovaries have no area of involvement greater than 5mm. Descriptions such as "bulky mass," "omental caking" probably indicate an ovarian primary. Descriptions such as "seeding," "studding," "salting" probably indicate a peritoneal primary. |

20041094 | CS Extension/Histology (Pre-2007)--Breast: Paget disease with underlying DCIS. How should CS Extension, SEER Summary Stage 2000, histology, and behavior be coded? | 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. For tumors diagnosed prior to 2007:
Based only on the information provided above, 1. The CS extension code is 07 [Paget disease of nipple (without underlying invasive carcinoma pathologically)]. 2. The SS 2000 stage is 1 [Localized]. 3. The histology code is 8543 [Paget disease and intraductal carcinoma of breast]. The behavior code is 3 [Malignant].
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. |

20041100 | Sequence Number-central/Multiple Primaries (Pre-2007): What criteria are to be used to determine which primary site carries a worse prognosis? Should we take survival into consideration? See Discussion. | In the case of two or more simultaneously diagnosed primary tumors, instructions in the SEER manual state that the tumor with the worse prognosis is to be assigned the lower sequence number. Prognosis decisions should be based on primary site, histology and extent of disease. Stage as a criteria for decision making is fairly straightforward. On the other hand, decisions based on primary site seem to be more subjective than objective. |
For tumors diagnosed prior to 2007:
Compare the combination of the primary site, histology and extent of disease for each primary, and assign the lowest sequence number to the primary with the worst prognosis. Do not use primary site or histology alone to determine prognosis in the case of assigning sequence number. Survival is a component of prognosis. If there is no difference in prognosis, assign the sequence numbers in any order.
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. |

20041073 | Primary Site/Histology--Lymphoma: How are these fields coded when the final diagnosis per the pathology report is, "Soft tissue and skeletal muscle, left thigh--Large B cell lymphoma with polyclonal and mature t-cells, involving the soft tissue"? | For cases diagnosed prior to 1/1/2010:Site: C492 [Soft tissue thigh] Histology: 9680/36 [T-cell rich 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. |

20041050 | Surgery of Primary Site--Rectum: How do you code a procedure described as a "transanal resection, debulking of a large rectal mass"? See Discussion. | Patient is not a surgical candidate due to "other medical conditions". Colonoscopy done for anemia and rectal bleeding. At the colonoscopy a "Transanal Resection Debulking of large rectal mass" is performed. Two specimens are sent to the lab. The first is labeled "rectal mass" and is a 2.0 cm diameter spherical fragment of tissue. The second is labeled "transanal debulking rectal mass" and is described as multiple, irregular shaped fragments of tan, rubbery tissue measuring 5.0 x 5.0 x 3.0 cm. Final path diagnosis: Debulking of rectal mass: Adenocarcinoma greater than 2 cm in size, resection margins positive for tumor. | For cases diagnosed 1998-2002, code Surgery of Primary Site to 20 [Local tumor excision, NOS]. Because the procedure was performed via colonoscopy and apparently did not involve proctectomy, the best choice is a local excision. | 2004 |
|
|
20041023 | Histology (Pre-2007)--Lung: Should "moderately differentiated adenocarcinoma of scar type, intermixed with bronchiolo-alveolar carcinoma" be coded to 8250 [bronchiolo-alveolar adenocarcinoma, NOS] or 8255 [adenocarcinoma of mixed subtypes]? | For tumors diagnosed prior to 2007:
Code Histology to 8255 [Adenocarcinoma with mixed subtypes]. This is a single tumor containing both a scar carcinoma and a bronchiolo-alveolar carcinoma--use 8255. The synonym for 8255 is adenocarcinoma combined with other types of carcinoma (not just subtypes).
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. |

20041103 | Histology (Pre-2007)/Behavior Code/Sequence Number-Central -- Ovary: How are these fields coded for a "serous tumor of low malignant potential" when lymph nodes are discovered to be involved? | For tumors diagnosed 2001-2006:
This ovarian tumor is not SEER reportable if diagnosed between 2001-2006. The histology and behavior codes are 8442/1 [serous cystadenoma, borderline malignancy]. Sequence is coded appropriately from 60-88 [non-malignant tumor or central registry-defined neoplasm].
The behavior code could be changed to /3 only when the pathologist states that the disease is malignant. Approximately 20% of serous tumors of low malignant potential have lymph node involvement, according to the WHO Classification of Ovarian Tumours. In ovarian serous tumors of low malignant potential, lymph node involvement is not always equivalent to metastasis and does not signify malignancy in these tumors unless definitely stated as such by the pathologist.
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. |

20041019 | EOD-Extension--Lung: Is this field coded to 10 [tumor confined to one lung] or 20 [Tumor involving main stem bronchus >= 2 cm from carina] when there is no mention of the mainstem bronchus and a lobectomy is performed? See Discussion. | The clinical work-up shows a mass at the left medial apex extending into the left lung. No mention of the main stem bronchus. Because a lobectomy was performed, we assume, per Note 2, that the tumor was greater than or equal to 2 cm from the carina. | For cases diagnosed 1998-2003: Code the EOD-Extension field to 10 [tumor confined to one lung] for the case example. The EOD-Extension code 20 [Tumor involving main stem bronchus >= 2 cm from carina] applies to tumors involving the main stem bronchus. | 2004 |
