20000509 | EOD-Extension--Small Intestine: How do we interpret a pathology description of "extending through serosa and forming masses in the periserosal tissue" for a jejunum primary? | For cases diagnosed 1998-2003:
Code the EOD-Extension field to 55 [Invasion of/through serosa and adjacent connective tissue]. The description states the tumor extended through the serosa into periserosal tissue. The periserosal tissue in this case refers to adjacent connective tissue lying exterior to the intestinal wall and not the (sub)serosal tissue that lies exterior to the muscularis but inferior to the serosa. Analyze each case individually since pathologists are not consistent when using the above terminology. |

20000421 | Surgery of Primary Site/Reconstruction-First Course--Breast: If the plan is to "reconstruct" the breast 6 months after an ipsilateral modified radical mastectomy, is the time span a problem or should it be coded in the Surgery of Primary Site field because it was planned? | For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 55 [Modified radical mastectomy WITHOUT removal of uninvolved contralateral breast, Implant]. The time span is not a problem as long as the reconstruction was planned as first course, which is indicated by tissue expander insertion at the time of the original surgery. | 2000 | |

20000844 | EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined--Colon: What codes are used to represent these fields when the pathology from a colon cancer resection describes 2/16 positive pericolonic lymph nodes and a "metastatic nodule in the pericolonic fat"? | For cases diagnosed 1998-2003:
Code the Number of Regional Lymph Nodes Positive field to 03 and the Number of Regional Lymph Nodes Examined field to 17. Each grossly detectable nodule in the pericolonic fat is counted as one regional lymph node. |

20000259 | Histology (Pre-2007): What code is used to represent the histology for a "malignant invasive gastrointestinal stromal tumor (GIST)"? | For tumors diagnosed 2001-2006: Malignant GIST is coded 8936/3.
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. |

20000261 | EOD-Extension--Lymphoma: What code is used to represent a non-Hodgkin lymphoma presenting with involvement of an extralymphatic organ and lymph nodes on the opposite side of the diaphragm? | For cases diagnosed 1998-2003: Code the EOD-Extension field to 31 [30 + localized involvement of an extralymphatic organ or site; Stage III E]. | 2000 | |

20000280 | Primary Site--Breast: Is there a hierarchy for coding subsite for breast cases when there is conflicting information in the physical exam, mammogram, operative and pathology reports as to the exact location of the primary? See discussion. | Example: Two mammograms were performed. One report indicates the lesion is at 12:00 and the other indicates it is in the upper central quadrant. However, the pathology report from the modified radical mastectomy specimen indicates the mass is in the UIQ.
According to one of our physicians, when a pathologist has a mastectomy specimen with attached axillary contents, the location of the lesion (subsite) is very accurate. |
Code the Primary Site field to C50.2 [upper inner quadrant]. In general, the priority for using information is pathologic, operative, and clinical findings. The pathology report would take precedence in this case. The 2004 SEER Program Code manual will include the following instructions for determining breast subsite. Priority Order for Coding Subsites Use the information from reports in the following priority order to code a subsite when the medical record contains conflicting information: 1 Pathology report 2 Operative report 3 Physical examination 4 Mammogram, ultrasound If the pathology proves invasive tumor in one subsite and insitu tumor in all other involved subsites, code to the subsite involved with invasive tumor. |

20000474 | Date of Diagnosis: If a clinician states his current diagnosis of malignancy is based on a CT scan done at an early date that contained a diagnosis of only "neoplasm" or "worrisome for carcinoma" should the date of diagnosis be the date of the scan? | Yes. Code the Date of Diagnosis field to the date of the scan. The physician's clinical impression upon reviewing the earlier scan, is that the malignancy was confirmed by the scan. If there is a medical review of a previous scan that indicates the patient had a malignancy at an earlier date, then the earlier date is the date of diagnosis, i.e., the date is back-dated. | 2000 | |

20000484 | EOD-Size of Primary Tumor--Breast/Cervix: When coding tumor size, when do you use 997 for breast cases and 000 versus 999 for breast and other primaries? See discussion. | Example 1: Ductal carcinoma found in axillary lymph nodes. No tumor found in breast on physical exam or by pathological exam of the breast, but physician states that the breast is definitely the primary site.
Example 2: Paget disease for breast carcinoma with no underlying tumor.
Example 3: Inspection of the cervix shows no visible tumor; biopsy of the cervix reveals CIN III or squamous cell carcinoma, either invasive or in situ. |
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary Tumor field as follows:
Example 1: Code to 000 [No mass, no tumor found, no Paget disease] when a tumor of a stated primary site is not found, but the tumor has metastasized.
Example 2: Code to 997 [Paget disease of nipple with no demonstrable tumor] if there is no underlying tumor and the patient presents with Paget of the breast.
Example 3: Code to 999 [Size not stated] when no size of tumor is given on the pathology report. Do not use 000 in the size field when a tumor is not visible on physical exam or by imaging, but tumor is found microscopically. |

20000248 | Date of Diagnosis: When doing follow-back at nursing homes on DCO cases, we find it difficult to code diagnosis date because the nursing home records are often vague or incomplete. Should the diagnosis date be coded as unknown (excluded from SEER database), the date of death, or the approximate date of diagnosis as reported on the death certificate? | If the nursing home record indicates that the patient had cancer, use the best approximation for date of diagnosis.
If the record says the patient had cancer when admitted, but it does not provide a date of diagnosis, use the date of admission as the date of diagnosis.
If there is no mention of cancer in the nursing home record and/or all work-up in the record is negative, assume the cancer was discovered at autopsy. Use the date of death as the date of diagnosis, and leave as a Death Certificate Only case. |

20000842 | Surgery of Primary Site--Skin: Explain the difference between code 30 and code 45.
Code 30 [Biopsy of primary tumor followed by a gross excision of the lesion]
Code 45 [Wide excision or re-excision of lesion or minor (local) amputation with margins more than 1 cm, NOS. Margins MUST be microscopically negative.] |
For cases diagnosed 1/1/2003 and after: Code 30 represents a biopsy or excision in which the margins of excision are less than 1 cm or the margins are unknown. Code 45 represents a wide excision in which it is known that the margins of excision are greater than 1 cm. | 2000 |
