First course treatment--Anus: Is the topical application of trichloroacetic acid to an anal condyloma with AIN III first course treatment coded to 10 [Local tumor destruction, NOS] in the Surgery of Primary Site field?

Code the trichloroacetic acid treatment of reportable AIN III in the "Other Therapy" field. Assign code 1 [Other].

20100022 Multiple primaries/Histology--Heme & Lymphoid Neoplasms: Is a 2010 diagnosis of ALK+ anaplastic T cell lymphoma following a 2008 diagnosis of follicular B cell lymphoma, grade 1 a new primary? If so, how is the histology coded? See Discussion. A patient has a history of Stage 4 follicular B cell lymphoma, grade 1 [9695/3] diagnosed in 2008. The patient was treated with Adriamycin, Cytoxan, Rituxan, and Prednisone. In 2010, the medical oncologist states the patient has progression/recurrence of lymphoma with pathology that has changed to anaplastic T cell lymphoma ALK+. There was immunophenotyping, but there was no more specific diagnosis made. The patient died within 3 months.

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

Abstract the anaplastic T cell lymphoma as a new primary. Code the histology to 9714/3 [Anaplastic large cell lymphoma, ALK-positive].

Rule M15 applies to this cases which instructs you to use the Multiple Primaries Calculator. The result for 9695/3 and 9714/3 is "New Primary."

Apply Rule PH30 to code histology which instructs you to use the Heme DB to determine the histology when rules PH1-PH29 do not apply. In searching the Heme DB for "anaplastic" the first term returned is Anaplastic large cell lymphoma, ALK-positive [9714/3].

20100074 Laterality--Melanoma: For a melanoma case, does the term "mid" imply that the tumor is in the midline when the site is the skin of back (trunk)? Yes. When the location is described as mid-back or mid-chest with no indication of left or right, assign laterality code 5 [midline]. 2010
20100094

Primary site--Heme & Lymphoid Neoplasms: Is a peripheral blood equivalent to bone marrow biopsy for the purposes of Rule PH26 and code the primary site to C421 [Bone marrow] for a marginal zone lymphoma found in peripheral blood when there was no additional workup (e.g., scans, etc.) for this case?

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

Code the primary site to C421 [bone marrow]. Our hematopoietic specialty physicians state that involvement of peripheral blood is equivalent to bone marrow involvement because the marrow produces blood. In the absence of any other involvement, per Module 7 (Coding primary sites for lymphomas) Rule PH26, it states to code the primary site to bone marrow when the only involvement is bone marrow.

MP/H Rules/Multiple primaries: Please clarify how rule M10 for Other Sites was developed and how a "recurrence" of the tumor after one year was determined to be a new primary? See Discussion.

What is the expected outcome or result of rule M10? Specifically, for soft tissue sarcomas, why is a recurrence after one year a new primary instead of a recurrence?

For cases diagnosed 2007 or later: Rule M10, tumors occurring more than one year apart are multiple primaries, was developed to differentiate a new primary from a recurrence. The rule was developed with the concurrence of the CoC site-specialty physicians and the SEER consulting pathologist. There was agreement between all of the CoC site teams and the consulting pathologist that statements of recurrence should not be relied upon to rule out a new primary. The time limits for each site were set based on information from peer-reviewed articles on tumors occurring in the same site and studies using molecular studies to confirm whether or not the tumors were histologically similar. Determination of the time limit for the "other sites" rules was probably the most difficult because so many sites are involved. However, the specialty-physicians felt that one year was an appropriate length of time to apply to these sites.

20100008 Primary site--Bladder/Unknown & ill-defined sites: Should the coding of primary site be based on a molecular study when it is not verified by a clinical correlation? See Discussion.

Patient was seen in 2009 at Hospital A for bone pain and was found to have metastatic adenocarcinoma. A paraffin block specimen was sent to BioThernostics for THEROS CancerTYPE ID Molecular Cancer Classification Tests. The results came back with a 94% likelihood that the urinary bladder was the primary site. No scans were done on the abdomen or pelvis.

The patient was then sent to Hospital B for radiation to the bones and chemotherapy (Carboplatin and Taxol). The patient died within 6 months.

According to Hospital A, the primary site is bladder based on the molecular study report. Hospital B says this is an unknown primary. Which is correct? Do we take primary site from these tests, even when no clinical correlation is documented?

 Code primary site to bladder in this case. Code the known primary site when given the choice between a known primary site and an unknown primary site. 2010
20100020 Histology/Behavior--Brain and CNS: How are these fields coded for a "cystic glioma"? Code the histology 9380/3 [Malignant glioma; Glioma, NOS]. There is no specific code for cystic glioma. 2010
20100101 Multiple primaries--Heme & Lymphoid Neoplasms: Is a 10/2010 diagnosis of accelerated phase of CML following a 4/2010 diagnosis of blast phase CML a new primary? See Discussion.

Patient was diagnosed in the blast phase of CML on a 4/2010 bone marrow biopsy. Pt failed Gleevec and progressed to the accelerated phase of CML in 10/2010.

Is this a single primary? This is not addressed in the hematopoietic rules. If this is a multiple primary, what rule should be applied?

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

Per Rule M2 this is a single primary because there is only a single histology represented for this case.

Under the Alternate Names section in the Heme DB for chronic myelogenous leukemia (CML), NOS [9863/3 and chronic myelogenous leukemia, BCR-ABL1 positive [9875/3] it indicates CML-blast phase, CML-accelerated phase and CML-chronic phase are all synonyms for CML, NOS. Any combination of these terms diagnosed represents one disease process. The Gleevec was given to prevent or delay progression to the accelerated phase.

20100112 Primary site--Heme & Lymphoid Neoplasms: Is C448 [overlapping lesion of skin] or C449 [skin, NOS] the appropriate site code for a 2008 diagnosis of mycosis fungoides involving over 40 percent of the skin surface, including both upper and lower extremities and trunk? Code the primary site to C449 [skin, NOS]. The code C448 should be used when there is a single overlapping lesion that includes all the disease. The patient has extensive skin coverage involving multiple skin subsites (upper and lower extremities and the trunk), but it is unlikely there is ONE plaque (one lesion) overlapping all these different skin subsites. The disease has more likely presented as multiple plaques (lesions) in these different areas. 2010

Reportability--Heme & Lymphoid Neoplasms: Is "myeloproliferative syndrome, NOS" synonymous with "myeloproliferative syndrome" and "myeloproliferative disease" and, therefore, reportable under the new hematopoietic rules?

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

Myeloproliferative syndrome and the myeloproliferative diseases were used in the past to describe myeloproliferative neoplasms. For cases diagnosed 2010 and forward, although the term "myeloproliferative syndrome" is not currently used to describe this disease, the synonyms "myeloproliferative syndrome" and "myeloproliferative disease" were added to the database for myelodysplastic/myeloproliferative neoplasm, unclassified [9975/3].
