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?

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

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).

20130051 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when biopsies of the left and right tonsils show diffuse large B-cell lymphoma and there is no other evidence of involvement? See Discussion. Scans are negative for lymphadenopathy and the bone marrow biopsy was benign. Radiation Oncology staged this as localized bilateral tonsil primary lymphoma.

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

This case should be accessioned as a single primary, diffuse large B-cell lymphoma [9680/3] of bilateral tonsils. Per Rule M2, a single histology is a single primary. Note 1 for Rule M2 states bilateral involvement of lymph nodes and/or organs is still a single primary.

20130148 Reportability--Brain and CNS: Are "spinal" schwannomas reportable if stated to be extradural, vertebral nerve sheath, or of specific vertebrae? See Discussion.

Are any of the following cases reportable?

Example 1: Clinical Diagnosis: Extradural spinal cord tumor compatible with schwannoma. What assumptions should be made about reportability if the tumor is described as being extradural? The extradural spinal cord includes epidural fat surrounding the thecal sac and exiting nerve roots. Does this mean there are not nerve roots in the extradural spinal cord?

Example 2: Final Pathologic Diagnosis: Designated "C3-4 nerve sheath tumor" excision: Morphologic and immunohistochemical findings consistent with cellular schwannoma. When stated to be a "nerve sheath tumor" does that mean peripheral nerve (C47_) involvement or nerve root (C72_) involvement?

Example 3: Final Pathologic Diagnosis: T-8 vertebral tumor resection: Schwannoma with degenerative changes (calcification, cyst formation) - ganglion and nerve are identified. There is no mention clinically or pathologically whether this tumor is "intradural" or "of the nerve root." In the absence of information about whether the location of the tumor is intradural or involving the nerve root, is it assumed that it does involve this part of the spinal cord when a specific vertebrae is removed?

Extradural schwannomas are not reportable. Neither vertebral nerve sheath nor a location of/on a specific vertebrae confirm the origin as being either extradural or intradural. Do not report a schwannoma if it cannot be determined to be "intradural" or "of the nerve root." 2013

Reportability--Is "intraductal papillary mucinous neoplasm with low grade dysplasia" (also called IPMN adenoma) reportable? See Discussion.

According to the ICD-O-3, the histology for IPMN adenoma is 8453/0 is non-reportable. However, per SINQ 20021099, this is reportable.

Intraductal papillary mucinous neoplasm (IPMN) of the pancreas with low grade dysplasia, also referred to as IPMN adenoma, is not reportable.

IPMN of the pancreas is reportable when stated as "IPMN with high-grade dysplasia," or "IPMN with an associated invasive carcinoma," or  "IPMN with an associated in situ carcinoma."

The case in SINQ 20021099 is stated to have "multifocal high grade dysplasia (so-called borderline tumor and carcinoma in-situ)" and is reportable because there is an explicit statement of carcinoma in situ, not because of the reference to the presence of high grade dysplasia. It is coded 8453/2 [Intraductal papillary-mucinous carcinoma, non-invasive].

20130045 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if subsequent to a bone marrow biopsy diagnosis of acute myeloid leukemia there is an oncology consult note that indicates the pathology finding is suggestive of an underlying myelodysplastic syndrome? See Discussion

5/14/12 Bone marrow biopsy: Acute myeloid leukemia (AML).

5/21/12 Oncology consult: AML with 30-40% blasts and evidence of del(20q) and del(5q), is suggestive of an underlying myelodysplastic syndrome (MDS). Hence the patient has secondary AML.

If these are two primaries, how are the diagnosis dates coded?

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

This case is accessioned as a single primary diagnosed on 5/14/12 as acute myeloid leukemia with myelodysplasia-related (e.g., del(5q)) changes [9895/3] per Rule M2. The patient was diagnosed with a single histology, acute myeloid leukemia with myelodysplasia-related changes per the submitted information.

20130028 Primary site--CLL/SLL: How is the primary site coded and what rule applies when no bone marrow biopsy is performed on a patient diagnosed with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) which was based on the results of an axillary biopsy, positive peripheral blood and a CT scan showing multiple lymph nodes involved above and below the diaphragm? See Discussion The physician staged this as Stage 0 CLL/SLL. Should the primary site be coded to lymph nodes if the MD stated this was leukemia?

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] per Rule PH5. Code the primary site to the bone marrow when the peripheral blood is involved, even if no bone marrow biopsy is performed.

According to the notes for Rule PH5, CLL always has peripheral blood involvement (PH5 Note 1). CLL/SLL may also have involvement of lymph node regions in later stages (PH5, Note 2). For this patient a bone marrow biopsy was not performed but he had extensive lymph node and peripheral blood involvement. Therefore, the primary site is coded to C421. In addition, the physician's documentation specifies this patient has Stage 0 disease which indicates this disease process is being classified as leukemia (CLL).

20130191 Systemic/Surgery Sequence--Bladder: How is the systemic treatment/surgery sequence field coded for a 2013 case if the patient has a TURBT followed by multi-agent chemotherapy, and then a cystoprostatectomy followed by post-operative multi-agent chemotherapy? For cases diagnosed in 2012 and later, code 7 (surgery both before and after systemic therapy) seems like the most appropriate answer. However, previous SINQ entries 20091055 and 20071102 have conflicting answers regarding surgery before and after systemic therapy. Do these SINQ entries apply to a 2013 diagnosis? Would the systemic treatment/surgery sequence be coded 7 because this patient had surgery then chemotherapy followed by more surgery? Should the post-operative systemic treatment be ignored in coding the sequence in this case?

Code the Systemic/Surgery Sequence to 7 [surgery both before and after systemic therapy] for this case.

The answers to SINQ 20091055 and 20071102 do not apply to a case diagnosed in 2013. These answers were posted prior to code 7 becoming effective in 2012.

MP/H Rules/Histology--Bladder: What is the histology code histology code for a bladder TUR that demonstrates mixed invasive urothelial and small cell carcinoma? See Discussion.

SINQ 20041104 (prior to 2007 MP/H rules) states to code histology to 8045. The MP/H rules do not address this combination of urothelial and small cell carcinoma. The current MP/H rule that applies is Rule H8, code the higher histology (8120/3). However, if the histology is coded to 8120/3, the fact that small cell carcinoma exists will be lost. If the small cell carcinoma drives the treatment plan/prognosis, shouldn't this situation be reflected in the rules for coding histology?

Code the histology to 8045/3 [mixed small cell carcinoma]. The presence of small cell carcinoma drives the treatment decisions for this case.

This issue will be addressed in the next revision of the MP/H rules.

Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How many primaries are reported if a 2010 inguinal lymph node biopsy diagnosis of follicular lymphoma, grade 1 is subsequently diagnosed in 2012 with a 50% follicular, grade 3 and 50% diffuse large B-cell via a biopsy of an axillary mass?

In 2010 a left inguinal lymph node biopsy revealed follicular lymphoma, grade 1. There were no other suspicious lymph nodes in the body.

In 2012 a biopsy of a large axillary mass revealed a a 50% follicular, grade 3 and 50% diffuse large B-cell.

According to the rules, the transformation to a B-cell is new primary. Is the mixed cell neoplasm a single primary?

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

There are two reportable primaries for this case -- follicular lymphoma in 2010 and DLBCL in 2012.

First determine the histologies needed to to determine the number of primaries to report. We determined the histologies are follicular lymphoma, grade 1 for 2010 and DLBCL for 2012 as follows:

  •  
  • Rule M4, a mix of DBLCL and follicular lymphoma, grade 3 is 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). Additionally, the instruction per Rule PH11 indicates one is to code the histology to diffuse large B-cell lymphoma (DLBCL) (9680/3) when DLBCL and any other non-Hodgkin lymphoma (i.e., follicular lymphoma, grade 3) are present in the same lymph node(s), lymph node region(s), organ(s), tissue(s) or bone marrow.

Per the Hematopoietic database, follicular lymphoma (all types are chronic) transforms to DLBCL (acute). Per Rule M 10 instructions, "Abstract as multiple primaries when a neoplasm is as a neoplasm there is a of an neoplasm after the chronic diagnosis." Therefore, abstract the DLBCL as a second primary.

20130195 Laterality--Heme & Lymphoid Neoplasms: Is laterality coded to 0 [not paired] for all lymphoma cases including paired sites (e.g., breast, lung)?

Laterality coding for lymphomas is based on the primary site not histology. Laterality describes the side of a paired organ or side of the body on which the reportable tumor originated. Determine whether laterality should be coded for each primary.

Laterality coding instructions are located in the SEER Program Coding and Staging Manual. See pages 68-70 in the 2013 manual,
