20110010 | Multiple primaries--Heme & Lymphoid Neoplasms: Is a recently diagnosed granulocytic sarcoma followed by a diagnosis of AMLÂ 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. SEER*Educate provides training on how to use the Heme Manual and DB.

20110061 | Primary site/Histology--Heme & Lymphoid Neoplasms: Should the primary site and histology codes be updated when a patient with a history in 2005 of a bone marrow diagnosis of chronic lymphocytic leukemia later presents in 2010 with lymph node biopsy diagnosis of small B-cell lymphocytic leukemia? |
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 a single histology. Code histology to 9823/3 [CLL/SLL]/ The distinction of CLL vs. SLL cannot be made on bone marrow biopsy in isolation. The pathologist cannot make a diagnosis of CLL vs SLL without having peripheral blood counts available for review. If the patient was treated for CLL in the past, that may alter the peripheral counts seen in 2010 (e.g., lymphocytosis). The distinguishing feature is peripheral lymphocytosis in CLL (not seen in SLL). The disease looks the same and both will often have bone marrow involvement and lymph node involvement. If the patient had true CLL in 2005, then any subsequent lymph node (or other) biopsy consistent with CLL/SLL remains consistent with the original diagnosis of CLL. I would not change the original CLL code. I agree with the previous response. We have to assume the 2005 diagnosis included a peripheral blood supporting that diagnosis. Otherwise, CLL and SLL look the same in nodes and marrow. The interplay between the two "diseases" is expected. This is why they are considered a single disease.

20110154 | Behavior--Breast: Is a breast biopsy diagnosis of "ductal carcinoma in situ with focal and very early stromal invasion" an invasive tumor with a behavior code 3? |
Code the behavior to /3 [malignant, invasive]. "Stromal invasion" means the cancer is invasive. "Stroma" is the supporting connective tissue around and between ducts. It is outside the duct basement membrane. If the tumor cells extend into the stroma, the proper behavior designation for the tumor is invasive. |

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.

20110040 | Reportability--Melanoma: Is a pathology report with a final diagnosis stating only non-reportable terms, followed by a re-excision pathology report that indicates "no residual melanoma" reportable? See Discussion. |
Is a case reportable if the final diagnosis on an initial pathology report states a non-reportable term (e.g., evolving melanoma, early/evolving melanoma or melanocytic nevus) and followed by a subsequent re-excision pathology report stating there is "No residual melanoma"? There is no mention in the clinical history on the subsequent pathology report that the diagnosis was thought to be melanoma following the first procedure. The first mention of the reportable term was in the final diagnosis of the subsequent pathology report that stated "no residual melanoma." |
No. This case is not reportable based on the information provided. "No residual melanoma" is not diagnostic of a reportable neoplasm. We recommend that you try to obtain more information from the clinician/pathologist for this case due to the poor documentation. Check for any additional resection performed. |

20110031 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if patient initially diagnosed with granulocytic sarcoma on a vocal cord biopsy is subsequently diagnosed with acute myeloid leukemia more than 21 days later? See Discussion. | The patient has a history of refractory anemia with excess blasts diagnosed in 2008. A vocal cord biopsy performed on 6/2/2010 stated, "in view of a previous history of myelodysplastic syndrome this is indicative of transformation to acute leukemia" and consistent with granulocytic sarcoma. A bone marrow biopsy done on 7/19/2010 stated this was compatible with refractory anemia with excess blasts in transformation.
Granulocytic sarcoma is a solid manifestation of AML. When these diagnoses occur more than 21 days apart, are they separate primaries?
According to the WHO definition, this is acute myeloid leukemia complicating myelodysplasia. Which rule applies for this case? |
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. The first is refractory anemia with excess blasts in 2008, and the second is AML June 2, 2010.
As for the disease occurring in 2010, 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.
In this case, when the physician gave a provisional diagnosis of "transformation to acute leukemia" it indicated he saw the solid deposits of myeloid cells on the vocal cord. Per Rule M3, AML and myeloid (granulocytic) sarcoma appearing simultaneously are a single primary coded to AML. When the patient has AML, solid myeloid deposits (myeloid sarcoma) may appear. This is a manifestation of the AML rather than a new primary. Rule PH10 states to code the histology to AML.
Under the Transformation section in the Heme DB for refractory anemia with excess blasts (a chronic neoplasm), it indicates this disease process does transform to acute myeloid leukemia, NOS (an acute neoplasm). In this case, the chronic and acute disease processes were diagnosed at different times. Per Rule M10, abstract as multiple primaries when a neoplasm is originally diagnosed in a chronic (less aggressive) phase AND second diagnosis of a blast or acute phase more than 21 days after the chronic diagnosis.

20110042 | MP/H Rules/Histology--Testis: How is histology coded when the initial biopsies of retroperitoneal mass demonstrated non-seminomatous germ cell tumor, but after neoadjuvant chemotherapy the final diagnosis on the radical orchiectomy specimen demonstrated mature teratoma, NOS (not stated to be malignant)? See Discussion. | A large retroperitoneal mass was found on CT scan. A biopsy demonstrated non-seminomatous germ cell tumor. The biopsy was done at an outside facility. Neither the CT scan nor biopsy pathology report is available for review. Following neoadjuvant chemotherapy, the retroperitoneal mass decreased to 12 cm. Subsequently, the patient had a right radical orchiectomy. The final diagnosis per the pathology reports was a 3.5 cm mature teratoma (NOS, not stated to be "malignant") of right testicle. The patient then had resection of the retroperitoneal mass and biopsies. Pathology showed the "excision" specimen contained 6 benign lymph nodes and two of the "biopsy" specimens showed non-seminomatous germ cell neoplasm with IHC findings suggestive of a mix of embryonal carcinoma and a lesser component of yolk sac tumor. | This is a reportable case. Even though the pathology from the orchiectomy stated mature teratoma, NOS, the presence of lymph node metastases proves that this tumor is malignant. Code the histology as 9065/3 [germ cell tumor non-seminomatous].
The majority of germ cell tumors show the presence of multiple histologies. While the original tumor showed only mature teratoma, there were obviously yolk sac cells that were not detected on the sections taken from the primary tumor. Both teratoma and yolk sac are germ cell tumors. This explains why the pathologist gave you the diagnosis of germ cell tumor. The classification of "non-seminomatous" simply means that there was no seminomas present in the mixture of germ cell histologies. |

20110041 | Histology--Heme & Lymphoid Neoplasms: How is this field coded when the final diagnosis for excisional biopsy of two cervical lymph nodes shows classical Hodgkin lymphoma, histologic subtype cannot be determined, but the COMMENT section of the report indicates there are features of both lymphocyte rich and nodular sclerosis subtypes? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule PH28, code histology to 9650/3 [Classical Hodgkin lymphoma]. This rule states to code the non-specific (NOS) histology when the diagnosis is one non-specific (NOS) histology and two or more specific histologies.

20110005 | Histology--Heme & Lymphoid Neoplasms: How is the pre-2010 histology coded for a "follicular grade 2, non-Hodgkin lymphoma with marginal zone B-cell differentiation"? See Discussion. | This patient was seen in 2010 for the same primary as diagnosed in 2006. The histology was coded to marginal zone lymphoma [9699/3] in 2006. Is this correct? Or should this have been coded as a follicular lymphoma, ignoring the modifying expression "marginal zone B-cell differentiation"? | This is a 2006 diagnosis. The histology code is 9691/3 [follicular lymphoma, grade 2]. Do not code differentiation for hematopoietic cases.
For diagnoses 2010 and forward, a small number of cases of follicular lymphoma do have marginal zone differentiation. However, there is no code for this variant of follicular lymphoma. It would simply be coded as a follicular lymphoma because that is the most accurate histology code available. The marginal zone differentiation is not to be coded as a second primary (marginal zone lymphoma). |

20110144 | Reportability--Heme & Lymphoid Neoplasms: Is steroid resistant idiopathic thrombocytic purpura (ITP) the same as refractory thrombocytopenia [9992/3]? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Idiopathic thrombocytic purpura (ITP) is not a synonym for refractory thrombocytopenia (RT). ITP is not a reportable disease. See Appendix F.
Under the Alternate Names section in the Heme DB, the only synonym for refractory thrombocytopenia is "RT." ITP is not listed as a synonym for refractory thrombocytopenia.
