20051001 | Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Lung: How is histology coded for the tumor(s) that exist if a left upper lobe of lung resection final diagnosis states the patient has a moderately differentiated adenocarcinoma and the path indicates there are "multiple carcinoid tumorlets"? | For tumors diagnosed prior to 2007:
Histology is coded 8140/3 [adenocarcinoma]. This is one reportable tumor of the left lung. According to our pathologist consultant, the tumorlets are collections of cells which appear to be of neuroendocrine origin, but are not 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. |

20041104 | Histology (Pre-2007)--Bladder: What is the correct histology code for this tumor of the bladder? See Discussion. | TURBT was performed with invasive residual tumor remaining - path report reads "Mixed carcinoma of the urinary bladder, with components of invasive high grade urothelial carcinoma, invading deep muscle, and small cell carcinoma." | For tumors diagnosed prior to 2007:
Code combined small cell carcinoma [8045]. This mixed carcinoma is both urothelial and small cell. It is important to capture the small cell information in the code because the prognosis for small cell is different from pure urothelial carcinoma.
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. |

20041102 | CS Tumor Size--Breast: How is this field coded when a core needle biopsy removes the majority of the tumor? See Discussion. | Rule 4.j on page 128 of the 2004 SEER Manual states "Do not code the tumor size from a needle biopsy unless no residual tumor is found on further resection". Example: 3/04/04 core biopsy Rt breast grade 1 infiltrating ductal carcinoma tumor size 0.8cm. 3/10/04 Lumpectomy: 3mm focus of residual infiltrating ductal carcinoma. If we can not take the size of the core needle biopsy, do we use the residual size of 3mm or the clinical size which was 1cm on mammogram? |
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 tumor size from the mammogram. Do not code the tumor size from the needle biopsy because residual tumor was present in the lumpectomy specimen. |

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. |

20041099 | First Course Treatment: If a patient makes a blanket refusal of all recommended therapy or refuses all treatment before any therapy was recommended, are only immunotherapy and hematologic/endocrine therapies to be coded as refused (code 87)? Or should all treatment modalities be coded as refused if a patient makes a blanket refusal? Or should none of the treatment modalities be coded as refused because we do not know what would have been recommended? See Discussion. | Coding instructions for immunotherapy and for hematologic/endocrine procedures state that Code 87 is to be assigned if either of the following circumstances apply: 1) If the patient made a blanket refusal of all recommended treatment. 2) If the patient refused all treatment before any was recommended. These instructions are not included for other treatment modalities. | When the patient refuses treatment, the first course of therapy is no treatment. Code all treatments as refused. | 2004 |

20041098 | Histology--Prostate: We are seeing numerous pathology reports with the following diagnosis: "Conventional (acinar) prostatic adenocarcinoma (M81403)." What is the correct histology code? | For cases diagnosed prior to January 1, 2007, assign histology code 8550/3 [Acinar adenocarcinoma]. | 2004 | |

|
20041097 | Reportability--Brain and CNS: Is a skull tumor schwannoma an intracranial reportable benign tumor if the physician states it arose in the occipital nerve? |
No. These schwannomas are not intracranial and therefore, are not reportable to SEER. The occipital nerve is not one of the 12 intracranial nerves (i.e., Abducens, Auditory (vestibulocochlear), Facial, Glossopharyngeal, Hypoglossal, Oculomotor, Olfactory, Optic, Spinal Accessory, Trigeminal, Trochlear, and Vagus). |

20041096 | Behavior Code--Breast: How is this field coded for a "non-invasive Paget disease of the breast?" See Discussion. | Historically, SEER collected Paget Disease of the breast with a behavior code of 3 [invasive]. There is no documentation to support this. The SEER EOD Manual only states that if the code is "05" [Pagets disease (without underlying tumor)], the behavior must be a 2 [in situ] or a 3 [invasive]. | Code the behavior as /2 [in situ] for noninvasive Paget disease of breast. Noninvasive is a synonym of in situ. If the pathology report documents that the Paget disease is in situ, the matrix principle in ICD-O allows you to change the behavior code to match the pathologist's statement. |

20041095 | Primary site: How is this field coded for a malignancy described as a "intracranial squamous cell carcinoma (8070) arising in a previous epidermoid cyst"? See Discussion. | 4-5-02 MRI Brain: Enhancing mass is probably a recurrence of the original tumor resected in 1983 (benign). 4-8-02 Gross resection. Lesion was coming up against her brain stem: Removed it grossly. Path: 4-8-02 Brain tumor, left temporal: SCC arising from a previous epidermoid cyst of the brain. XRT began 4-25-02. Path states: "Squamous lesions suspicious for malignant transformation of old epidermal cyst (1983). It has been reported in literature that epidermoid cysts in the brain can undergo a malignant transformation which is what happened in this case." It appears the patient has an intracranial epidermoid cyst that is now giving rise to SCC. Squamous cell carcinoma (8070) of the brain (C71_) fails the edit Primary Site, Morphology-Imposs ICDO3 (SEER IF38). |
Code the primary site to C760 [Ill-defined site; Head, face or neck, NOS]. There is an intracranial malignancy arising from a previously resected epidermoid cyst. Squamous cell carcinoma, primary of the brain, is a non-overridable edit error. | 2004 |
