Ambiguous Terminology--Breast: Is a stereotactic biopsy that is "focally suspicious for DCIS" reportable if it is followed by a negative excisional biopsy? See Discussion.
Per the 2004 SEER manual page 4, 1.a, the case is reportable based on the ambiguous term "suspicious" for DCIS.
Per the 2004 SEER manual page 4, 1.c, use these terms when screening diagnoses on pathology reports, operative reports, scans, mammograms, and other diagnostic testing other than tumor markers.
Note: If the ambiguous diagnosis is proven to be not reportable by biopsy, cytology, or physician's statement, do not accession the case.
Do not accession this case. The needle localization excisional biopsy was performed to further evaluate the suspicious finding found on stereotactic biopsy. The suspicious diagnosis was proven to be false.
Ambiguous terminology/Reportability--Thyroid: Should a thyroid case be accessioned based only on a cytology that is consistent with papillary carcinoma? See Discussion.
Instructions in the 2007 SPCSM state that we are not to accession a case based only on a suspicious cytology. Does this rule apply only to the term "suspicious" or does it apply to all ambiguous terms? Example: FNA of thyroid nodule is consistent with papillary carcinoma.
Do not accession the case if the cytology is the only information in the medical record. The phrase "Do not accession a case based only on suspicious cytology" means that the cytology is the only information in the record. If there is other information that supports the suspicion of cancer (radiology reports, physician statements, surgery), then accession the case. The phrase "suspicious cytology" includes all of the ambiguous terms.
Race, Ethnicity/Spanish Surname or Origin: Which Spanish Surname List (from 1980 census or 1990 census) would SEER prefer us to use to code 7 in Spanish Surname or Origin? See Discussion.
In the SEER coding manual, it refers to "a list of Hispanic/Spanish names" (5e), but does not specify which one to use. Again, for the Computed Ethnicity field, which Spanish Surname List does SEER prefer us to use?
Determine which list is better suited for your geographic area. If the 1990 list is used, determine the probability cut-off that seems most reasonable for your geographic area.
Grade, Differentiation--Bladder: Some pathologists use a two component grade system for bladder carcinomas - either low grade or high grade. Should we continue to code these per SEER rules as grades 2 [low grade] and 4 [high grade]? See discussion.
The AFIP website states that this low grade classification corresponds to grade 1/3, while the high grade corresponds to both grade 2/3 and grade 3/3. Using the 3-grade conversion, this would also classify the low grade as grade 2, but would leave the high grade as a toss-up between grade 3 and grade 4.
Continue to code Grade, Differentiation as specified in the SEER Program Code Manual: "Low grade" is coded to 2 and "high grade" is coded to 4.
Type of Multiple Tumors/Multiplicity Counter--Breast. Are the data items "Type of Multiple Tumors Reported as One Primary" and "Multiplicity Counter" related? How should they be coded for breast cases in which there are multiple measured invasive tumors, plus DCIS which is not measured nor stated whether it is separate from the invasive tumors? See Discussion.
For example, path report states only "multifocal invasive ductal carcinoma, 1.5 cm and 0.8 cm, and low-grade DCIS." The Multiplicity Counter instructions tell us to ignore/do not count foci that are not measured. Should we interpret this to mean, count only the two invasive foci and ignore the DCIS? Should Type of Multiple Tumors then be coded 30 or 40, because only the invasive tumors are coded in Multiplicity Counter?
Code Type of Multiple Tumors 30 [in situ and invasive]. The code in Type of Multiple Tumors may or may not reflect the tumors that were counted in Multiplicity Counter. For this case, it is correct to code 02 in multiplicity counter.
EOD-Size of Primary Tumor: Can size be coded from a needle bx that removes all of the invasive tumor and just leaves a "focus of in situ"? See Description.
For example: needle bx diagnosis is "tiny focus of tissue highly suspicious for tubular ca." The lumpectomy path states "single focus of low grade DCIS, no residual ductal ca." Can size be coded 001?
Code tumor size to 001 [Microscopic focus or foci only] for the invasive component. Code the tumor size 990 for cases diagnosed in 2004 and forward. Disregard the microscopic tumor found at further resection.
Immunotherapy/Radiation Therapy: Is I-131 labeled immunoglobulin coded as immunotherapy or radiation therapy?
Code treatment with I-131 labeled immunoglobulin as radiotherapy. The primary action is radiotherapeutic. Radioimmunotherapy (RIT) uses antibodies to deliver the radiotherapy to the site of the tumor.
Primary site--Melanoma: Should melanoma of the nipple be coded to C50.0 [Nipple] or C44.5 [Skin of the trunk]?
Code to C44.5 [skin of trunk]. External melanoma is an epidermal malignancy, beginning in melanocytes in the basal layer of the epidermis. C50.0 excludes skin of breast.
