Smoldering multiple myeloma [9732/3] has always been a reportable neoplasm. Per the Abstractor Notes section in the Heme, smoldering multiple myeloma is a variant of multiple myeloma in which the diagnostic requirements for multiple myeloma are met, but there is no organ damage. The patient is usually asymptomatic.
Smoldering myeloma is listed under the Alternate Names section in the Heme DB for multiple myeloma [9732/3] to clarify that it is a reportable neoplasm.
Report all new diagnoses of smoldering multiple myeloma now. Registries are not required to spend time and effort to find these cases if they have not been reporting them in the past. However, report earlier earlier cases if encountered today while performing casefinding or chart review procedures.
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.
CS Extension--Lymphoma: In the absence of physician staging, is an "enlarged" spleen seen on CT coded as involvement of the spleen for lymphoma cases?
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.
Do not code spleen involvement when the only evidence is an enlarged spleen.
When imaging is the only diagnostic tool (no biopsy or splenectomy), spleen involvement is based on the presence of nodules and not on enlargement. Splenic enlargement alone (by physical exam or imaging) is insufficient to support involvement of spleen.
Histology (Pre-2007)/Behavior Code: What code is used to represent the histology "foci of well differentiated intramucosal carcinoma [carcinoma in situ] arising on the surface of a tubular adenoma"? The pathologist referred to this colon biopsy as "in situ".
For tumors diagnosed prior to 2007:
Assign histology code 8210 [adenocarcinoma in a tubular adenoma] and behavior code 2 [in situ]. "In situ" is specified by the pathologist.
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.
Reportability--Bladder: Please explain the reportability of UroVysion for bladder cancer in the following circumstances.
1. Patient has positive UroVysion test and follow up biopsy is negative. Is this case reportable with a diagnosis date the date of the UroVysion?
2. Patient has positive UroVysion test and follow up biopsy is positive for cancer. Is the diagnosis date of the date of the positive UroVysion or the date of the positive biopsy? Thank you.
Do not report a case based on UroVysion test results alone. Report a case when there is positive histology, a physician statement of malignancy, and/or the patient was treated for cancer.
Surgery of Primary Site--Melanoma: If the surgical margins are greater than 1 cm for length and width but less than 1 cm for depth, do we code surgery in the 30-33 range?
Yes, assign a surgery code from the 30-33 range when any margin is less than 1 cm. Since tumor thickness is an important prognostic factor for cutaneous melanoma, the deep margin is of particular importance.
EOD-Lymph Nodes--Breast: Are lymph nodes described as being either "keratin positive" or "keratin positive for metastasis" to be coded as involved lymph nodes?
For cases diagnosed between 1998-2003:
Lymph nodes that are only "keratin positive" would not be coded as involved lymph nodes. The pathologist uses this expression to mean that the nodes stained positive for keratin that does not mean they are also involved with cancer.
However, if the pathologist uses these stains to make a definitive diagnosis of metastatic carcinoma (i.e., uses the expression "keratin positive for metastasis"), then code the nodes as involved.
CS Extension--Prostate: For a tumor that is clinically inapparent, but a biopsy from the prostatic apex is positive, is this field coded to 15 [Tumor identified by needle biopsy, e.g., for elevated PSA (clinically inapparent)]?
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.
Yes. Code CS Extension-Clinical Extension to 15 [Tumor identified by needle biopsy, e.g., for elevated PSA (clinically inapparent)] for clinically inapparent prostate cancer with positive apex biopsy.
MP/H Rules/Histology--Melanoma: How should histology be coded for a melanoma arising in a compound nevus, NOS or a nevus, NOS?
For cases diagnosed 2007 or later, assign code 8720 [Melanoma, NOS] to melanoma arising in a nevus that does not have a specific code or to melanoma arising in a nevus, NOS.
Currently, ICD-O-3 does not have a specific classification for a melanoma arising in a compound nevus.
MP/H Rules/Histology--Colon: When the microscopic description indicates a colon tumor is "tubulovillous," but the final diagnosis only states "adenocarcinoma," is the histology coded to 8263/3 [adenocarcinoma in a tubulovillous adenoma]?
For cases diagnosed 2007 or later:
Yes. This is an example of a site-specific exception to the general rule to code only from the final diagnosis. The Colon Histology Rules specifically state that "other parts of the pathology report" may be used to identify a tumor arising from a polyp, adenomatous polyp, villous adenoma, or tubulovillous adenoma.
MP/H Rules/Multiple primaries -- Ovary: How many primaries are to be accessioned and what rule applies when a patient has a serous carcinoma of the right ovary treated with neoadjuvant chemotherapy followed by a debulking surgery that revealed a serous tubal intraepithelial carcinoma of the left fallopian tube?
For cases diagnosed 2007 or later, accession two primaries, serous carcinoma of the right ovary and serous tubal intraepithelial carcinoma of the left fallopian tube based on the information provided.
The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text) and go to the Other Sites MP rules because neither the ovary nor fallopian tube have site specific rules developed.
Start at the MULTIPLE TUMORS module, Rule M3. The rules are intended to be reviewed in consecutive order within a module. The patient has multiple tumors with ICD-O-3 topography codes that are different at the third character (Cxx) and therefore this case should be accessioned as a multiple primary.
It could be helpful to know the extent of involvement noted prior to neoadjuvant therapy and debulking surgery. For example, if the patient had widely metastatic disease throughout the entire pelvis prior to the initiation of treatment, the answer may have been different.
