Date of Conclusive Terminology: Is there an applicable timeframe when coding this field?
There is no strict timeframe for Date of Conclusive Terminology. The diagnosis using conclusive terminology could be made any time following the diagnostic work-up.
The date of conclusive terminology is related to code 2 [ambiguous term followed by conclusive term] in the data item "Ambiguous terminology." Assign code 2 when a conclusive diagnosis is made 60 days or more after a diagnosis using ambiguous terminology. Record the date of the conclusive diagnosis in "Date of Conclusive Terminology."
MP/H Rules/Histology--Fallopian Tube: What is the histology code of serous tubal intraepithelial (in situ) carcinoma (STIC), bilateral fallopian tubes?
Assign 8441/2. This is based on the WHO classification for female reproductive system tumors.
Update to Current Manual/Neoadjuvant Therapy--Pancreas: How are the neoadjuvant items coded for a patient who has unresectable pancreatic cancer and starts chemotherapy but will be evaluated after X cycles to see if patient may become a surgical candidate?
Assign the neoadjuvant therapy data items as if the patient had neoadjuvant therapy. Neoadjuvant Therapy data item would be coded either code 1 or 2 depending on whether the chemotherapy was completed or not. In this case, they are a surgical candidate by having the chemotherapy with the plan from the beginning to evaluate the chemotherapy after X cycles to see if surgery can be performed. After the patient is evaluated, update the abstract as needed.
Primary Site--Ovary/Peritoneum: Should this field be coded to ovary or peritoneum when the bulk of the tumor is in the peritoneum and there is only surface involvement of the ovary?
If it is not clear where the tumor originated, use the following criteria to distinguish ovarian primaries from peritoneal primaries.
The primary site is probably ovarian, unless:
--Ovaries have been previously removed
--Ovaries are not involved (negative)
--Ovaries have no area of involvement greater than 5mm.
Descriptions such as "bulky mass," "omental caking" probably indicate an ovarian primary.
Descriptions such as "seeding," "studding," "salting" probably indicate a peritoneal primary.
Update to current manual/Lymphovascular invasion: Are lymphvascular invasion and lymphvascular space invasion on a pathology report the same thing or do they describe different things?
We confirmed with our expert pathologist consultant that lymphovascular invasion and lymphovascular space invasion are synonymous.
Reportability--Brain and CNS: Are spinal schwannomas and neurofibromas reportable or non-reportable?
The most accurate and most current instruction is to report these spinal tumors when they arise within the spinal dura or spinal nerve roots, or when they are stated to be "intradural" or "of the nerve root." Do not report these tumors when they arise in the peripheral nerves. The peripheral nerves are the portion of nerve extending beyond the spinal dura.
Reportability--Brain and CNS: Are lipomas of the spinal column reportable as a benign tumor of the central nervous system (CNS)? This is seen occassionally at our pediatric facility.
Spinal cord tumors (including lipomas) are reportable when they arise in the spinal dura or nerve root. The tumor must be of the spinal cord itself or within the spinal cord dura. Spinal cord tumors are reportable when they arise in the intradural space. A reportable intradural tumor can be either intramedullary or extramedullary. Extramedullary intradural spinal tumors are reportable. A spinal tumor originating in the extradural space is not reportable. If it is outside the dura, it is not reportable because it would be outside the CNS. They are not reportable when they arise in the peripheral nerves.
Solid Tumor Rules (2018, 2021)/Histology--Kidney: What is the correct histology code for a kidney primary described as clear cell papillary renal cell carcinoma"? Should we use H2 and code 8312/3 or H3 and code 8323/3?
Assign 8323/3, clear cell papillary renal cell carcinoma using the 2018 Kidney Solid Tumor Rules, Rule H1, as this is a single histology, a variant of renal cell carcinoma NOS.
Neoadjuvant Treatment/Date Therapy Initiated--Breast: If Tamoxifen has been used since 2000 for the treatment of hyperplasia, should it be coded as neoadjuvant treatment for a 2004 diagnosis of breast cancer?
Do not code tamoxifen given for hyperplasia as treatment for breast cancer. In this case, tamoxifen started four years before the breast cancer diagnosis -- not treatment for breast cancer.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient was treated in 1999 with Vidaza for myelodysplastic syndrome and had a recent biopsy that demonstrated a transformation to acute myeloid leukemia?
This case should be accessioned as a single primary, acute myeloid leukemia [9861/3].
MDS diagnosed prior to 1/1/2001 is not a reportable disease process. However, because MDS is currently a reportable disease process, it must be considered when trying to determine whether the AML represents a separate primary.
If the Heme DB indicates MDS and AML represent different (separate) disease processes, only one primary is reported (i.e., AML) because the 1999 diagnosed MDS is not reportable.
If the Heme DB indicates MDS and AML represent the same disease process, then no primaries are reported because MDS was not reportable in 1999.
Rule M2 does not apply to this case because more than one histology is mentioned in the scenario. According to the Heme DB, MDS can transform to AML. Rules M8-M13 apply to cases involving transformation. In this case, Rule M10 applies because the patient was diagnosed with a chronic neoplasm (myelodysplastic syndrome) followed greater than 21 days later by an acute neoplasm (AML).
