This is accessioned as one primary and the histology is coded to 9732/3 [multiple myeloma].

To arrive at this answer, it is important to first try to determine how many different unique neoplasms there are to correctly identify the number of primaries to report. Per the Heme DB, plasma cell leukemia is an obsolete term. The current term and histology code for this diagnosis is 9732/3 [plasma cell myeloma]. Plasma cell myeloma and multiple myeloma are synonyms per the Heme DB. Therefore, per Rule M2 a single primary exists when there is a single histology. That takes care of the multiple myeloma/plasma cell myeloma and plasma cell leukemia, but not the plasmacytoma.

In checking the Heme DB, the terms plasma cell myeloma and multiple myeloma are not synonyms for plasmacytoma. Therefore, we are left to determine whether the multiple myeloma/plasma cell myeloma vs the plasmacytoma represents one or two primaries.

Under the Transformation section of the Heme DB, it indicates that plasmacytoma (a chronic disease process) transforms to multiple myeloma (an acute disease process). Per Rule M9, abstract a single primary and code the acute histology when both a chronic and an acute neoplasm are diagnosed simultaneously. The histology is coded to the acute neoplasm when there is no information on the biopsy regarding which is the "later" histology. This update will be added to the Heme Manual.

No. Polycythemia, NOS is not reportable.

Polycythemia (also known as polycythaemia or erythrocytosis) is a disease state in which the proportion of blood volume that is occupied by red blood cells increases. Blood volume proportions can be measured as hematocrit level. It can be due to an increase in the mass of red blood cells, "absolute polycythemia"; or to a decrease in the volume of plasma, "relative polycythemia".

The phlebotomy is a treatment for the excessive blood volume; therefore, a diagnosis of "polycythemia" without one of the modifying terms listed in the Heme DB under Alternative Names is not reportable.

For tumors diagnosed prior to 2007:

Code the Primary Site field to C61.9 [prostate] because the histology is adenocarcinoma.

When a malignancy is identified in the prostatic urethra, look at the histology to determine the primary site. If it is a transitional cell carcinoma, code the Primary Site field to C68.0 [urethra] and if it is an adenocarcinoma, code to C61.9 [prostate].

The EOD scheme is ultimately collapsed into the TNM scheme. The TNM system differentiates between adenocarcinoma of the prostate and transitional cell carcinoma of the urethra. Only adenocarcinoma of the prostate is staged by the prostate scheme. Transitional cell carcinoma of the prostatic urethra is coded to C68.0 [urethra] and staged with that scheme.

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.

For cases diagnosed 1998-2003:

With the exception of those sites/histologies that require 99 in these fields, code the Number of Regional Lymph Nodes Positive field to 97 [Positive nodes but number of positive nodes not specified]. Code the Number of Regional Lymph nodes Examined field to 95 [No regional Lymph nodes removed, but aspiration of regional Lymph nodes was performed].

Code OPTUNE in the Other Treatment field. See NovaTTF in SEER*Rx (http://seer.cancer.gov/seertools/seerrx/). NovaTTF is the pre-FDA approval name for OPTUNE.

If OPTUNE was administered for recurrence, be sure NOT to record it in the first course of treatment fields. Check with CoC if you have questions about coding treatment for recurrence.

For tumors diagnosed prior to 2007:

Assign code 8720/3 [malignant melanoma, NOS] for malignant melanoma arising in a compound nevus. A compound nevus is not the same as a junctional nevus.

ICD-O-3 does not have a specific code for melanoma in a compound nevus. Assign the code for the type of melanoma specified; for example, NOS, superficial spreading, etc.

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.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

This is a single primary per Rule M2 which indicates to abstract a single primary when there is a single histology. Code the histology to 9590/3 [lymphoma] and the primary site to C629 [testes. Unless your software has edits that prevent coding laterality for lymphomas, code the laterality as bilateral. Up to half of extranodal lymphomas occur in multiple sites, particularly in paired sites.

Assign diagnostic confirmation code 5 for a positive laboratory test/marker study. A note was added to the Hematopoietic manual to state that code 5 now includes cases with no histological confirmation but there is positive immunophenotyping or genetic studies.

Intramucosal carcinoma of the colon is assigned behavior code of /3. Intramucosal is not the same as in situ in terms of behavior. Behavior and staging are separate concepts, although there is some overlap. Use the instructions for coding behavior to code this field. Do not use stage to determine behavior in this case.

For purposes of Summary Stage, intramucosal carcinoma is a localized lesion; however, for purposes of AJCC staging, assign Tis for the stage.
