Histology--Pancreas: How is a "gastrin and somatostatin producing endocrine neoplasm" coded that has lymph node metastasis?
The best code available for this situation is 8153/3 [Gastrinoma, malignant].
Many pancreatic endocrine tumors produce more than one peptide, such as gastrin and somatostatin in this case. ICD-O-3 does not provide a code for pancreatic endocrine tumors which produce more than one peptide. According to the WHO Classification of Tumours of Endocrine Organs, there is a distinct hormonal syndrome associated with gastrin producing tumors, and not with many of the somatostatin producing tumors. Therefore, our pathologist consultant advises us to code to gastrinoma in this case.
Reportability--Brain and CNS: In addition to Schwannoma, are there additional types of benign tumors that arise in peripheral nerves along the spinal cord that are not reportable? See Discussion.
Are neuroepitheliomatous neoplasms such as ganglioneuroma, gangliocytoma, ganglioglioma occurring along the spinal cord reportable? Are nerve sheath tumors such as neuroma occurring along the spinal cord reportable? Angioma?
Reference: SINQ 20051071; Primary Central Nervous System Tumors, NPCR Training Materials 2004
Reportability depends on the location of the tumor. Tumors in the following sites are reportable:
C700 - C709
C710 - C719
C720 - C729
C751 - C753
Benign and borderline tumors of the peripheral nerves (C47_), including peripheral nerves along the spinal cord, are not reportable.
Please note: spinal schwannomas arising in the nerve root or spinal dura are reportable.
MP/H Rules--Bladder: Does rule M6 mean that any combination of tumors with the histologies 8050, 8120-8124, or 8130-8131 are the same primary regardless of the amount of time between tumor occurrences? See Discussion.
Many interpret Rule M7 to mean when separate occurrences of TCC of the bladder are diagnosed more than 3 years apart, it is reportable as a second primary. However, doesn't Rule M6 mean that if the histology is any combination of 8050, 8120-8124 or 8130-8131 for tumors diagnosed more than 3 years apart, they are reported as a single primary?
For cases diagnosed 2007 or later:
Papillary, transitional cell and/or papillary transitional cell carcinomas of the bladder are a single primary using Rule M6. Rule M6 includes diagnoses within 3 years of each other AND diagnoses more than three years apart for the histologies listed. If rule M6 applies to your case, stop. Do not continue on to Rule M7.
CS Site Specific Factor/Melanoma: How is CS SSF1 (depth of invasion) coded for a melanoma that demonstrates dermal invasion to a depth of "less than .2 mm" be coded to 999 [unknown]? See Discussion.
The path report says "superficial spreading malignant melanoma; 2 areas of papillary dermal invasion to depth of less than .2mm."
The revised CS pages include codes for "less than" a certain tumor size, but these are not included in the depth of invasion SSF. Using 999 results in an unstageable melanoma, when we know it is "less than .2mm".
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 SSF1 (depth of invasion) to 019 [.19mm]. For any case with an SSF1 code in the range of 001-100 mm, the T category will be determined using CS extension and SSF2 [ulceration]. All cases with an SSF1 code in the range of 001-100 mm will map to a T1 (either T1NOS, T1a or T1b).
MP/H Rules/Histology--Breast: Which report and diagnosis should be used to code the histology if an excisional biopsy that removes the majority of the tumor has a diagnosis of "carcinoma," and the subsequent lumpectomy diagnosis is "microscopic residual disease consistent with infiltrating duct carcinoma"?
For cases diagnosed 2007 or later, code histology for this case to 8010 [carcinoma]. The histology is coded from the pathology report with the most representative specimen (the most tumor tissue) even when the most representative specimen has a less specific histology.
Ambiguous Terminology: How is this field to be coded when there is a "conclusive term" exactly 60 days following the initial diagnosis? See Discussion.
Is code 1 [Ambiguous terminology diagnosis only within 60 days of initial diagnosis] or code 2 [Ambiguous term followed by a conclusive term more than 60 days after the initial diagnosis] to be used for a case that had a conclusive diagnosis at 60 days from initial diagnosis? The instructions on page 97 do not match the code definitions on page 95.
The definition for code 2 should be "More than 60 days" after the date of diagnosis.
Code 1 is 60 days or less, code 2 is more than 60 days.
This will be clarified in the first revision to the MP/H manual.
Primary Site: Is an "angiosarcoma" stated as arising in the skin of the breast and treated with a mastectomy, coded to the primary site of skin or breast?
Code the primary site as skin of breast when skin of breast is documented as the site of origin.
According to the WHO classification of soft tissue tumors, the majority of angiosarcomas "develop as cutaneous tumors...less than one quarter present as a deep soft tissue mass."
Reportability/Chemotherapy--Hematopoietic, NOS: Is pyridoxine-responsive sideroblastic anemia (SA) reportable and is pyridoxine coded as chemotherapy for SA and refractory anemia with ringed sideroblasts (RARS)? See Discussion.
Patient has refractory anemia with ringed sideroblasts on bone marrow path. The physician mentions it might be due to pyridoxine deficiency. Per the SEER*Rx, pyridoxine (aka Vitamin B6) is not coded as treatment. What causes RARS and SA? Is pyridoxine treatment for either disease process? Or is the pyridoxine just treating one aspect of the anemia? The patient has no other treatment but this.
For cases diagnosed prior to 1/1/2010:Sideroblastic anemia (SA) is not reportable. SA is not the same as refractory anemia with ringed sideroblasts (RARS). Therefore, do not code pyridoxine administered for SA as therapy. If the patient had RARS that "might be due to pyridoxine deficiency," the replacement pyridoxine would not be coded as chemotherapy because it does not control or kill malignant cells. If the pyridoxine was successful in alleviating the refractory anemia, the RARS would be reversible and would not meet the criteria for a reportable blood disease; i.e. irreversible, clonal.
For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
CS Site Specific Factor--Prostate: Given that the CS Manual instruction is to code the highest PSA value recorded in the medical record, can a PSA value obtained a year prior to admission be used to code the SSF 1 and SSF2 fields?
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.
The PSA recorded in CS SSF 1 and 2 must be documented in the medical record. Record the highest PSA value prior to diagnostic biopsy or treatment. If the highest PSA value documented in the medical record is from the previous year, record it.
MP/H Rules/Multiple Primaries: When the pathology report from a FNA or other biopsy states an "in situ" carcinoma and the patient waits more than 60 days for a more definitive procedure which documents an "invasive" carcinoma, is this reported as two primaries?
For cases diagnosed 2007 or later:
No. When the invasive component is discovered as part of the work-up phase leading to treatment decisions, the case should not be abstracted as a multiple primary. In the rare instance when a patient has not been treated and is still having diagnostic work-up greater than 60 days after the malignancy is diagnosed, do not count the invasive diagnosis as a new primary.
