20051080 | Priorities/CS Extension--Lung: In the absence of a physician TNM, is there a hierarchy associated with coding extension when multiple imaging studies demonstrate different degrees of extension? See Discussion. | CT of the lung showing primary lesion and other nodules in another lobe or contralateral lung, subpleural nodules, etc. The PET scan did not show activity for the other nodules. What is our "hierarchy" for imaging studies when there is no physician staging? | 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. There is no hierarchy among the various imaging studies. Assign CS extension based on the report documenting the greatest extension. |

20091048 | Surgery of Primary Site--Lymphoma/Soft Tissue: How is this field coded for an excision of a neck mass that found lymphoma in soft tissue (C49.0)? See Discussion. | CT scan showed soft tissue mass in the retropharynx. 9/23/2008 Laryngoscopy with biopsy taken of left tonsil and left base of tongue and random biopsies of nasopharynx; FNA of left neck. Path stated left tonsil, squamous papilloma. Left base of tongue, no significant histopathology. Nasopharynx biopsies, compatible with tonsillar tissue. Pretracheal lymph node biopsies, mild reactive lymphoid hyperplasia. 9/30/2008 Excision of left neck mass with limited deep jugular chain lymph node dissection. Path stated lymph node left jugular biopsy, no tumor seen. Soft tissue, left neck biopsy, malignant B cell lymphoma with plasmacytoid differentiation. Addendum from consult: favor a diagnosis of a marginal zone lymphoma. Per the gross description, the specimen was fibrofatty connective tissue in which there is a tumor infiltrate. | Assign code 26 [partial resection]. Use the surgery codes that apply to the primary site. See page C-597 of the 2007 SEER manual for surgery of primary site codes applicable to primary sites of soft tissue coded to C490 - C499. | 2009 |

20000485 | EOD-Extension--Lung: Should the phrase "some pleural fluid in both posterior gutters" be interpreted as pleural effusion for lung primaries? See discussion. | CT scan: "3 cm mass left upper lobe of lung. Some pleural fluid in both posterior gutters. Large matted hilar lymph nodes, left. Some narrowing left upper bronchus by this adenopathy. Squamous cell ca lung with mets to left hilar lymph nodes, most likely possibility." Would you code extension to 72 [malignant pleural effusion; pleural effusion, NOS]? | For cases diagnosed 1998-2003:
Yes. Code the EOD-Extension field to 72 [malignant pleural effusion, pleural effusion, NOS]. Pleural effusion is mentioned as being present. |

20021090 | Primary Site--Ovary/Peritoneum: How should the Primary Site field be coded when no resection is done and it is uncertain whether the primary site is in the ovary or the peritoneum? See discussion. | CT: ascites, omental cake and peritoneal studding. H&P impression: probable ovarian or peritoneal primary. Repeat CT: no enlarged adnexal mass seen to suggest ca of ovary, but possibility couldn't be ruled out. Omental bx: Metastatic ca. Comment: "IHC stains have been performed and are not typical of ovarian ca, although do not exclude an ovarian primary." After the bx, there were two clinical diagnoses written a month apart with no evidence of further work-up between those dates. The first diagnosis was "ovarian ca". The second was "Peritoneal carcinomatosis 2 month ago; Primary is unknown, possibly ovarian." | Use the best information available to identify the primary site. In this case, it is the physician's clinical assessment. Code the Primary Site to C56.9 [Ovary] for this example because the ovary is indicated to be the primary site according to the physicians involved.
When there is no surgical procedure involving the removal of the ovaries, code the Primary Site based on the clinical assessment of the disease location. If the disease is only noted to be in the peritoneum, code site to peritoneum, NOS. If the disease is seen clinically in both the ovary and the peritoneum, code site to ovary. |

20020057 | Histology (Pre-2007)--Melanoma: What code is used to represent the histology "radial growth phase: melanoma, superficial spreading type; vertical growth phase: epithelioid type"? See discussion. | Can the "growth phase" be used to code histology? If so, would the histology be epithelioid cell melanoma (8771/3)? | For tumors diagnosed prior to 2007:
Code the Histology field to 8771/3 [epithelioid cell melanoma]. The "growth phase" information in this case describes the horizontal spread and the "invasive" or vertical growth through the layers of skin.
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. |

20051108 | Reportability--Brain and CNS: Which types of neurofibromatosis are reportable to SEER? See Discussion. | Clin exam: probable neurofibromatosis, type I. On the trunk alone are >14 cafe au lait spots all at least 10mm. Both axillary regions have freckling. No palpable fibromas, spine is straight, no organomegaly. MRI of head: no abnormality. | Neurofibromatosis type I (von Recklinghausen's disease, the Elephant Man disease) is primarily tumors of the subcutaneous tissues. By itself, NF1 is not reportable. NF2 is much more likely to develop acoustic neuromas. This syndrome is reportable only when acoustic neuroma(s) is present, because the acoustic neuroma is what is reportable. This case is not reportable because none of the symptoms affect the central nervous system. | 2005 |
|
20041064 | CS Tumor Size/CS Extension/CS TS/Ext-Eval--Breast: How do you code these fields when the tumor size and extension differ pre and post treatment with neoadjuvant Arimidex? See Discussion. | Clinically on PE 3 cm mass attached to skin with dimpling and erythema overlying the mass. Ultrasound: 2-3 cm breast mass with overlying skin thickened by US evaluation, suggesting dermal invasion. Neoadjuvant Arimidex followed by MRM. Path: 4.5 cm ductal carcinoma (no DCIS), no invasion of skin. | 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.Record the larger tumor size and the farthest extension documented.
Code CS Tumor Size/Extension Evaluation to 6 [Surgical resection performed, WITH pre-surgical systemic treatment...; tumor size/extension based on pathologic evidence].
Code CS Tumor Size for the example to 045 [4.5 cm].
Code CS Extension to 20 [Local skin involvement ...] based on clinical description provided. |

20071025 | Radiation Therapy: How is radiation coded when it is "recommended" but the patient dies before radiation is started? See Discussion. | Code 0 seems appropriate but then we would lose the fact that it had been recommended. All of the other modalities give an option for 'recommended but patient died prior to treatment.' Is there a reason this option is not given for radiation? | Code Radiation (Rx Summ--Radiation) to 0 [None; diagnosed at autopsy].
SEER does not collect the Reason For No Radiation field. However, those who abstract using software that captures this data item can identify these cases. Code 5 [radiation not administered because patient died] reflects this situation.
Radiation (Rx Summ-Radiation) is a SEER field. This field is derived from the data collected in Rad-Boost Rx Modality and Rad-Regional TX Modality. These fields do not include a choice for "radiation not given because the patient died prior to treatment." Therefore, this information cannot be coded in the Radiation field. |

20071100 | Type of Multiple Tumors--Colon: How is this field coded for a case in which the patient is found to have two in situ polyps and an adenocarcinoma arising in a polyp all in the same segment of the colon? See Discussion. | Code 30 would not count the fact that these are polyps. Code 31 states "AND a frank adenocarcinoma." What would be the correct code? | Assign code 30 [In situ and invasive] in this case. Code 31 does not apply here because frank adenocarcinoma is not present. | 2007 |
|
20021190 | Histology (Pre-2007)--Bladder: What code is used to represent the histology "transitional cell and small cell carcinoma" of the bladder? See discussion. | Code 8045/3 is used for combination codes that represent a mixture of small cell carcinoma and any other carcinoma. When we use this histology code for bladder primaries with mixed transitional cell and small cell carcinoma, we encounter a problem with the SEER edits (site and morphology conflict). | For tumors diagnosed prior to 2007:
Please see SEER Inquiry question ID number 20041104.
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. |
