Report Question ID Question Discussion Answer Year
20021165 EOD-Size of Primary Tumor--All Sites: Is there a hierarchy for using information from clinical tests (scans, radiography) to determine clinical tumor size? When the size on a radiographic report prior to pathologic diagnosis is smaller than the size of the tumor on the radiographic report that is post pathologic diagnosis, which tumor size should be used? See discussion.

Which size should be used for these examples?

1) Tumor size on a mammogram is smaller than the tumor size on an ultrasound.

2) CT of the lung reveals a 2.5 cm RUL malignancy in June. A biopsy in July confirms a malignancy. A CT is done in August prior to initiating RT which reveals a 3.1 cm RUL nodule.

For cases diagnosed 1998-2003:

Generally, code the EOD-Size of Primary Tumor field to the largest size identified in any scan. Use the largest tumor size for most cases. There is no hierarchy for multiple imaging studies, with the exception of the two situations represented in the question examples.

1). Code the size stated on the mammogram, even if that size is smaller than the one specified on the ultrasound. Generally the mammogram size is more accurate for breast cases than ultrasound.

2). Code the EOD-Size of Primary Tumor field to 2.5 cm. In this example, the second scan was the same type as the first. Usually there is not that much of a difference in size between the same tests, unless the tumor has an aggressive histology. The example does not mention the histology. With certain histologies, such as small cell of the lung, a rapid growth in a short amount of time is the normal process. The fact that the size increased that much in a short period of time, using the same type of scan, is an indication of a rapidly growing tumor. It would be better to use the size on the initial scan to code the EOD-Size of Primary Tumor.

20020018 EOD-Lymph Nodes/EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined--Cervix: What codes are used to represent these fields for a cervix primary when the only information on lymph nodes is a CT of the pelvis showing "pelvic adenopathy" (no surgery was done)? Code the EOD-Lymph Nodes field to 9 [unknown]. Code the Pathologic Review of Number of Regional Lymph Nodes Positive field to 98 [No nodes examined] and the Lymph Nodes Examined to 00 [No nodes examined] because there was no resection of the primary organs. Adenopathy, NOS, per SEER guidelines, is not coded as lymph node involvement 2002
20021137 Multiple Primaries (Pre-2007)--Soft Tissue: Does SEER agree that one primary of the soft tissues of pelvis [C49.5] should be reported when a pathologic diagnosis for bilateral herniorrhaphies is "right and left inguinal hernias with low grade spindle cell sarcoma"?

For tumors diagnosed prior to 2007:

Yes. This is one primary and should be coded to C49.5 [Connective, subcutaneous and other soft tissue of pelvis]. According to Rule A in ICD-O-3, the type of tumor ("sarcoma") indicates origin from a particular tissue, resulting in the primary site code of C49.5 [Inguinal region, NOS] for this sarcoma.

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.

20021207 EOD-Lymph Nodes--Breast: How do you code this field when the gross description on the pathology report states "nodal tissue is matted" but only 1/18 lymph nodes is found to contain micrometastatsis per the microscopic description of the report?

For cases diagnosed 1998-2003:

Code the EOD-Lymph Nodes field to 1 [Micrometastasis] because the matted nodal tissue was found to contain only one node with micrometastasis when examined microscopically. Coding priority is given to the microscopic description over the gross description.

20020002 Date Therapy Initiated: What date should be entered in Date Therapy Initiated when treatment follows a surgical procedure that is not coded under Surgery of Primary Site? See discussion. If a patient has a surgical procedure that is not coded in the Surgery of Primary Site field and then the patient undergoes additional first course of treatment, such as radiation therapy, how should the Date Therapy Initiated field be coded? In this example, code the Date Therapy Initiated field to the date of the first surgical procedure. If a SEER edit is triggered, please notify us. 2002
20021131 EOD-Extension: If extension/metastasis is found within 4 months of diagnosis, but after first course of cancer-directed therapy has ended, should that involvement be excluded when coding the EOD-extension field? See discussion. Example: Spinal drop metastasis was diagnosed within 4 months of the initial diagnosis of a localized astrocytoma, but after treatment with surgery and XRT was completed.

For cases diagnosed 1998-2003:

Do not include the spinal metastasis because it was diagnosed after the extent of disease was established. If metastasis was not present at diagnosis, and not discovered during the original metastatic work-up, it is progression of disease.

20021185 Surgery of Primary Site--Major salivary gland: How do you code Surgery of Primary Site for a submandibular gland primary when the operative report refers only to an excision of the submandibular "tumor" while the pathology report states the submandibular "gland" was removed? See discussion. The gross description on the pathology report indicates that the specimen consists of a "submandibular gland." A further description on the pathology report included, "the specimen was sectioned exposing a focally cystic mass that nearly replaces the entire specimen." For cases diagnosed on 1/1/2003 or after: Code the Surgery of Primary Site field to 40 [Total parotidectomy, NOS; total removal of major salivary gland, NOS], per the pathology report's gross description of the specimen unless the operative report description of procedure indicates that the removal was less than total. 2002
20021059 Surgery of Primary Site--Soft Tissue: What code is used to represent this field when an excisional biopsy of a soft tissue sarcoma is followed two weeks later with a wide excision (re-excision)? For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 26 [partial resection]. According to the CoC, "Excision" in the surgery codes refers to the lesion and "partial resection" refers to the organ. The biopsy is a local excision (code 25). The wide resection is code 26, presuming that more than just the remaining lesion was removed. 2002
20021171 Date Therapy Initiated: How would you estimate the date treatment began for a patient who was treated elsewhere and seen only on an outpatient basis at the current facility? See discussion.

July 19th: Retromolar trigone primary was diagnosed.

August 8th note states, "Pt is not a surgical candidate due to multiple medical co-morbidities." Sept 19th note states, "Per Tumor Board, pt has been undergoing radiation for her head and neck cancer." The exact starting date for radiation is not specified.

In the SEER Program Code Manual it states that "In the absence of an exact date of treatment, the date of admission for that hospitalization during which the first cancer directed therapy was begun is an acceptable entry."

If possible, review the radiation treatment summary and outpatient records at the treating facility. If the date treatment began is not stated, look for the completion date and number of treatments, and calculate the first date of treatment.

If the date radiation started cannot be found or calculated, code the month as 09 for the example provided. The determination was made in August NOT to treat with surgery. We know that there was treatment in September.

Histology (Pre-2007)/Terminology: Are "pattern", "architecture", and "architectural pattern" terms that indicate a majority of tumor?

For tumors diagnosed 2004 to 2006:

The terminology "Architectural pattern: ____________," when used in the final pathology diagnosis, indicates a subtype that can be coded. This type of format in a pathology report is based on a College of American Pathologists (CAP) protocol. Disregard "pattern" and "architecture" when not used in accordance with the CAP protocol. See www.cap.org for cancer protocols.

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.
