Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when a patient is simultaneously diagnosed with multiple myeloma/plasma cell myeloma, plasmacytoma and plasma cell leukemia?

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

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.

20110134 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted, and what rule applies, when the patient has a 1999 diagnosis of Burkitt high grade B-cell lymphoma and was diagnosed in 2011 with diffuse large B-cell lymphoma? See Discussion Patient diagnosed in 1999 with Burkitt high-grade B cell lymphoma of the thyroid gland and cervical nodes. The patient was treated with a thyroidectomy and chemotherapy. A 2011 biopsy of the parotid gland is positive for diffuse large B cell lymphoma. The pathologist reviewed the 1999 and 2011 pathology reports and stated this is one primary.

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

This case should be accessioned as two primaries per Rule M15. Rule M15 instructs one to use the Heme DB Multiple Primaries Calculator to determine the number of primaries for all cases that do not meet the criteria of M1-M14. Code the histology for the 1999 primary to 9687/3 [Burkitt high grade B cell lymphoma] and code primary site to C739 [thyroid.] Code the second primary to 9680/3 [diffuse large B-cell lymphoma] with primary site coded to C079 [parotid gland] per Rule PH24 which instructs one to code the to the when lymphoma is present only in an .

20110053 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned for a patient with a several month history of refractory anemia with excess blasts (RAEB), that may or may not have been treated, who now presents with a bone marrow biopsy that is compatible with acute myeloid leukemia?

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

Per Rule M10, abstract multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm AND there is a second diagnosis of an acute neoplasm more than 21 days after the chronic diagnosis. Two primaries should be accessioned for this case: refractory anemia with excess blasts (RAEB) [9983/3] (a chronic neoplasm), and acute myeloid leukemia [9861/3] (an acute neoplasm).

Multiple primaries--Heme & Lymphoid Neoplasms: Is a recently diagnosed granulocytic sarcoma followed by a diagnosis of AML two primaries? See Discussion.

6/10/10 Axillary lymph node biopsy was compatible with AML. The physician noted that the patient was diagnosed with granulocytic sarcoma [9930/3] in the axillary node.

6/15/10 Bone marrow biopsy compatible with AML FAB M1 [9873/3].

After induction, a second bone marrow biopsy on 6/30/10 shows persistent/refractory AML. The physician noted that the second biopsy is compatible with AML FAB M7 [9910/3].

Is the granulocytic sarcoma a chronic form of the disease? If so, do we have one primary diagnosed 6/10/10 with primary site coded to C42.1 and histology coded to 9873/3? Does the second biopsy on 6/30/10 represent the same primary even though the persistent disease is now FAB M7?

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

Granulocytic sarcoma does not transform into AML. Per the Abstractor Notes section in the Heme DB under the term "granulocytic sarcoma," it indicates that "Myeloid sarcoma (also known as granulocytic sarcoma) may occur de novo; it may precede or coincide with AML, or represent an acute blastic transformation of myelodysplastic syndromes." This means that when granulocytic/myeloid sarcoma is seen with AML, it represents a solid manifestation of the systemically involved AML. In other words, it is all the same disease process (coded to AML) if it occurs simultaneously (i.e., at the same time or within 21 days of on another).

Apply Rule M3 to this case which states to abstract a single primary when a sarcoma is diagnosed simultaneously or after a leukemia of the same lineage. Code the primary site to C421 [bone marrow] with histology coded to 9873/3 [acute myeloid leukemia, M1]. The FAB category is an older classification that is seldom used. Changes from FAB 1 to FAB 7 do not constitute a new primary.

20110147 Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How is the histology coded when no bone marrow examination is performed but the peripheral blood flow cytometry listed several differential diagnoses and the physician states the diagnosis is small lymphocytic lymphoma? See Discussion.

The peripheral blood flow cytometry results state, "findings consistent with a small mature B-cell neoplasm, differential - marginal zone lymphoma, lymphoplasmacytic lymphoma, and atypical CLL." The physician states the diagnosis is "SLL." No bone marrow examination or CT scan was done to assess whether the patient had lymphadenopathy.

Per Rule PH5, if the diagnosis is B-cell CLL/SLL and peripheral blood is involved, the histology is coded to B-CLL/SLL [9823/3]. Should the primary site and histology be coded to bone marrow [C421] and CLL/SLL [9823/3] per Rule PH5 despite the physician's diagnosis of SLL [9670/3]?

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

This is a single primary and the primary site and histology is coded as bone marrow [C421] and CLL/SLL [9823/3]. The code 9670/3 [malignant lymphoma, small B lymphocytes, NOS] used for SLL is now obsolete.

Per the Abstractor Notes section in the Heme DB indicates that SLL is, "usually associated with CLL and coded CLL/SLL 9823/3. Small lymphocytic lymphoma (SLL) is almost identical to CLL. A somewhat arbitrary distinction is drawn between them based on the relative degree of marrow and nodal involvement and the numbers of circulating cells."

Per the Definition section in the Heme DB it states that, "CLL by definition involves blood and bone marrow at time of diagnosis." Check the PRIMARY SITE and MODULE RULE sections that indicate the primary site is C421, Rule PH5. Per this rule, code the primary site bone marrow (C421) and code the histology B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) [9823/3] when the diagnosis is B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) AND peripheral blood is involved (the bone marrow may also be involved).

This may appear to contradict the physician's diagnosis, but the 2008 WHO no longer codes CLL and SLL as separate neoplasms, rather one neoplasm, CLL/SLL, which reflects the actual neoplastic process. Those patients with SLL usually manifest CLL during the neoplastic process and those patients with CLL usually manifest SLL during the neoplastic process. WHO recommends coding to CLL/SLL rather than coding two primaries when the other neoplasm manifests.

20110035 Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded when both a lymph node biopsy and peripheral blood are positive for CLL/SLL? See Discussion. Per Module 3, Rules PH5 and PH6 in the Hematopoietic Manual, it states that CLL has peripheral blood involvement and SLL does not.

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] and histology to 9823/3 [CLL/SLL]. Per Rule there may be involvement of bone marrow AND lymph node(s), lymph node region(s), organ(s), or tissue(s) but as long as the peripheral blood and/or bone marrow are involved, the primary site is bone marrow (C421).

20110106 Primary site--Heme & Lymphoid Neoplasms: How is the primary site to be coded for a 2010 diagnosis of follicular lymphoma involving the spleen and lymph nodes above and below the diaphragm?

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

Use Rule PH21 to code the primary site to C778 [lymph nodes of multiple regions]. The spleen is not listed under the Primary Site(s) section in the Heme DB for follicular lymphoma. Per Rule PH21 code the primary site to multiple lymph node regions, NOS (C778) when multiple lymph node regions, as defined by ICD-O-3, are involved and it is not possible to identify the lymph node region where the lymphoma originated. The spleen is a primary site for only a few lymphomas (noted in the Heme DB). Because the spleen filters blood, it is often reactive (splenomegaly) or frankly involved with the lymphoma. That reaction or involvement, however, does not affect the primary site coding. Only the involved nodes are used in coding primary site.

20110058 Date of diagnosis/Flag: Will the Date of Diagnosis Flag ever be used if the instructions for coding Date of Diagnosis are followed? See Discussion.

If an abstractor follows the instructions for coding the Date of Diagnosis and can at least estimate a year of diagnosis, in what scenario will the Flag be used?

Per the 2010 SEER Manual,

Page 49 Date of Diagnosis, second paragraph, "Regardless of the format, at least Year of diagnosis must be known or estimated. Year of diagnosis cannot be blank or unknown." The manual gives the following guidelines for coding diagnosis date/flag:

Page 50, Coding Instructions:

3. If no information about the date of diagnosis is available

a. Use the date of admission as the date of diagnosis

b. In the absence of an admission date, code the date of first treatment as the date of diagnosis.

Page 51, Coding Instructions:

9. Estimate the date of diagnosis if an exact date is not available. Use all information available to calculate the month and year of diagnosis.

Page 53, Date of Diagnosis Flag, Coding Instructions:

Always leave blank. Date of Diagnosis will always be a full or partial date recorded.

 The date of diagnosis flag should always be blank. 2011
20110015 Primary site/Histology: Do the 4/1/09 changes in the ICD-O-3 Site/Type Validation table regarding the coding of primary site for intestinal type adenocarcinoma mean that the former valid site/histology combinations are now impossible and require review from a given diagnosis date forward? See Discussion.

Per the SEER Errata for ICD-O-3 Site/Type Validation List, April 1, 2009, adenocarcinoma, intestinal type, was removed as a valid site/histology combination for the following primary sites: C150-C155, C158-C159, C170-C173, C178-C179, C180-C189, C199, C209, C210-C212, C218.

  • Does this mean that these combinations cannot be used? If so, then why is an override allowed for these site/type combinations? Shouldn't these site/type combinations be added to the impossible site/type combinations table?

  • SINQ 20081085 states that "8144/3 will be removed from the valid site/histology list for large intestine, small intestine, and rectum." It appears from the Site/Type Validation table that a decision was made to also remove esophagus sites as a valid combination with histology code of 8144. Please explain the rationale.

  • Cases that were miscoded to 8144/3 will need to be identified for correction. What date of diagnosis should be the reference point used in making the necessary corrections related to this change? Do we only need to review cases diagnosed 1/1/2009 forward or should all cases be corrected regardless of date of diagnosis?

    • The site/type edit identifies unlikely combinations of primary site and histologic type.

  • Intestinal type adenocarcinoma occurs in the stomach. It would be rare in another primary site, but not impossible.

  • It was decided that all digestive organ sites, except stomach, would be removed from the list. That is why esophagus is not listed as a valid site.

  • The site/type edit is for all years. Cases for all years have to be reviewed for combinations of site and type that are no longer on the list. If it is documented in the medical record that the primary site and histology combination are valid, set the over-ride flag so that the case will not come up for review again.

    		20110039 Multiple primaries/Primary site--Heme & Lymphoid Neoplasms: What are the primary sites and how many primaries are abstracted, when 2004 diagnosis of grade 2 follicular lymphoma of the bilateral breasts is subsequently diagnosed with a 2010 diagnosis of diffuse large B-cell lymphoma (40%) and grade 3a follicular lymphoma (60%) of a left arm nodule? See Discussion.

    Follicular lymphoma was diagnosed 7/2004, grade 2 per biopsy of the bilateral breasts. Bone marrow biopsy was positive for lymphoma involving 10% of bone marrow. Imaging showed extensive lymphadenopathy mainly in abdomen/pelvis with an 8 cm mass in the right pelvis. Smaller lymph nodes were noted in the left periaortic region and also some small precarinal lymph nodes. This was a stage IVA lymphoma. The patient had six cycles of CHOP/R with an excellent response. Per the clinician's notes on 12/2005, there was no evidence of recurrence or no sign of active disease. The plan was to follow up with the patient in 6 months.

    08/22/06 imaging showed new disease in the bilateral chest wall. 8/2006 bilateral breast nodule biopsies, are positive for grade 1-2 follicular lymphoma. The patient was treated with Rituxan. Per clinician's 3/2007 note, no active disease is noted. Patient was regularly followed with no evidence of disease until 10/2010. At that time, the patient had a left arm nodule biopsy which was positive for diffuse large B cell lymphoma (40%) CD positive and grade 3a follicular lymphoma (60%). RICE was recommended due to "transformation" per oncologist.

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

    Per Rule M10, this case should be accessioned as two primaries when a neoplasm is originally diagnosed as a chronic neoplasm (is follicular lymphoma (FL), grade 2) AND there is a second diagnosis of an acute neoplasm (diffuse large B-cell lymphoma) more than 21 days after the chronic diagnosis.

    Code the histology for the first primary to 9691/3 [follicular lymphoma (FL), grade 2] and the primary site to bilateral C509 [breast, NOS]. FL can start as an extranodal disease; breast is one of the sites in which it originates. It is unlikely that the lymphoma extended from the nodes to the breast, but highly likely that it extended from the breast to the nodes.

    Per Rule M4, abstract the 2010 disease process as a single primary when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location(s), such as the same lymph node or lymph node region(s), the same organ(s), and/or the same tissue(s). Per Rule PH11 the primary site is coded to C779 [lymph nodes, NOS] and the histology is coded to 9680/3 [diffuse large B-cell lymphoma (DLBCL)]. Rule PH11 states one is to code the primary site to the site of origin, lymph node(s), lymph node region(s), tissue(s) or organ(s) and histology to diffuse large B-cell lymphoma (DLBCL) (9680/3) when DLBCL and any other non-Hodgkin lymphoma are present in the same lymph node(s), lymph node region(s), organ(s), tissue(s) or bone marrow.
