20100019 | Histology--Ovary: How is histology coded for an ovarian mucinous neoplasm of low malignant potential (borderline mucinous cystadenoma) that shows extensive intraepithelial carcinoma and focal microinvasion? See Discussion. | At surgery a 25 cm left ovarian mass is found adherent to the anterior abdominal wall. The final diagnosis per the pathology report is, "Mucinous neoplasm (26 cm) of low malignant potential (borderline mucinous cystadenoma) with extensive intraepithelial ca and focal microinvasion. Right ovary, fallopian tubes, uterus, omentum, biopsies of diaphragm, 28 para-aortic and pelvic LNS and peritoneal fluid are all negative for malignancy." | Histology code 8470/3 [mucinous cystadenocarcinoma] is the best choice in this case. There is a mucinous cystadenoma [8470/0] with intraepithelial carcinoma and focal microinvasion. 8470/3 comes as close as possible to the description of the tumor. | 2010 |

20100075 | Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How many primaries are to be accessioned when a 1/27/10 bone marrow biopsy, FISH and cytogenetics reveals chronic myelogenous leukemia (CML), BCR/ABL positive, t(9;22)(q34;q11) and a 4/15/10 bone marrow biopsy reveals B-acute lymphoblastic leukemia (Blast phase of CML)? | 1/27/10 BM biopsy: CML BCR/ABL+ FISH positive for BCR/ABL and cytogenetics showing the t(9;22)q34q11.2 translocation. Treated with Imatinib. 4/15/10 BM biopsy: B-acute lymphoblastic leukemia (Blast phase of CML). Would the term "blast phase of CML" indicate the 4/15/10 bone marrow biopsy showed CML or would a new primary be abstracted with histology coded 9811/3 [B lymphoblastic leukemia/lymphoma, NOS]?
Applying rule M10, this is a new primary, but note 2 states transformations are defined in the Heme DB. The Abstractor Notes section indicates CML has three phases: chronic, accelerated, and the blastic phase or blast crisis. The accelerated phase can last weeks to months. In the chronic phase the involvement is usually limited to blood, bone marrow and spleen although the liver may be infiltrated. During the blastic phase, lymph nodes and tissue may be involved. The blastic phase is a disease progression from the chronic phase. The disease, however, remains the same histology, chronic myelogenous leukemia. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case represents a multiple primary per Rule M15 which states you are 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.
The histology for the first primary is coded to 9875/3 [chronic myelogenous leukemia, BCR-ABL1 positive].
The histology for the second primary is 9811/3 [B lymphoblastic leukemia/lymphoma, NOS] in the absence of further documentation that the B-ALL was also positive for the t(9;22) translocation.
The histology code 9806/3 [Mixed phenotype acute leukemia with t(9;22)(q34;q11.2); BCR-ABL1] cannot be used for the second primary because there is no documentation that the B-ALL diagnosed on 04/15/2010 also had the t(9;22) translocation and this histology cannot be used in patients ." Per the Definition section in the Heme DB, in order to use histology code 9806/3 "This leukemia meets the criteria for mixed phenotype acute leukemia (MPAL) in which the blasts also have t(9;22) translocation of BCR-ABL1 rearrangement. Some patients with chronic myeloid leukemia may develop or even present with a mixed blast phase that would meet criteria for MPAL; however, this diagnosis should not be made in patients known to have had CML."

20100057 | First course treatment--Heme & Lymphoid Neoplasms: Is the use of the corticosteroid, Clobetasol, cancer-directed treatment for mycosis fungoides or is it only used to treat the side effects of that disease? | Clobetasol is not cancer-directed treatment at this time.
Note: Question originally submitted in 2010. During 2014 review, this was checked and Clobetasol is still not cancer directed treatment for Mycosis Fungoides. |

20100018 | Reportability/Heme & Lymphoid Neoplasms--Hematopoietic, NOS: Is light chain disease reportable if it is treated with chemotherapy agents? See Discussion. | A patient was diagnosed in 2010 with light chain disease based on SPEP and urine testing. Bone marrow aspiration and biopsy were done. Flow cytometry, cytogenetic studies and FISH for plasma cell disorders are all normal. Medical oncologist states diagnosis is light chain disease. Patient was started on Revlimid, dexamethasone and Velcade.
In reviewing the case reportability instructions, this seems to fall under Instruction 1, note 1. Immunoglobulin deposition disease, preferred term for light chain disease, is coded as 9769/1. This is normally a non-reportable diagnosis, but the patient was given cancer-directed treatment. Would this case be accessioned using the above morphology code and primary site of bone marrow [C42.1]? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case is not reportable. The histology is 9769/1 [light chain disease] in the Heme DB.
Light chains are produced in neoplastic plasma cells (multiple myeloma) and are called Bence-Jones proteins. The physician did the cytogenetic studies and FISH to rule out plasma cell disease. 50-60% of people with Light-chain deposition disease (LCDD) have an associated lymphoproliferative disorder, most commonly multiple myeloma. The remaining patients develop LCDD in the setting of progression of monoclonal gammopathy of unknown significance (MGUS) with no evidence of neoplastic plasma cell proliferation. This patient falls in this category, MGUS, which is not reportable. |

20100015 | Type of Multiple Tumors/Multiplicity Counter--Breast. Are the data items "Type of Multiple Tumors Reported as One Primary" and "Multiplicity Counter" related? How should they be coded for breast cases in which there are multiple measured invasive tumors, plus DCIS which is not measured nor stated whether it is separate from the invasive tumors? See Discussion.
|
For example, path report states only "multifocal invasive ductal carcinoma, 1.5 cm and 0.8 cm, and low-grade DCIS." The Multiplicity Counter instructions tell us to ignore/do not count foci that are not measured. Should we interpret this to mean, count only the two invasive foci and ignore the DCIS? Should Type of Multiple Tumors then be coded 30 or 40, because only the invasive tumors are coded in Multiplicity Counter? | Code Type of Multiple Tumors 30 [in situ and invasive]. The code in Type of Multiple Tumors may or may not reflect the tumors that were counted in Multiplicity Counter. For this case, it is correct to code 02 in multiplicity counter. | 2010 |

20100099 | Histology--Heme & Lymphoid Neoplasms: Should all cases of precursor B acute lymphoblastic leukemia diagnosed 1/1/10 and later with histology coded to 9836/3 have the values changed to 9811/3 per the Heme DB Abstractor Notes section or should they remain coded 9836/3. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
For cases diagnosed 2010 and forward, code histology to 9811/3 [B lymphoblastic leukemia/lymphoma, NOS] which is the new classification for pre-BALL. The histology code 9836/3 is obsolete as of 2010 and should not be used for cases with diagnosis date after 12/31/2009.

20100002 | Reportability/Histology--Colon: Is a colon tumor reportable if the pathology report final diagnosis is high grade dysplasia but CAP protocol histologic type designation is adenocarcinoma in situ? See Discussion. | The microscopic description and the final diagnosis on the pathology report indicate the tumor is a large tubulovillous adenoma of the cecum with focal surface high grade dysplasia. The CAP protocol histologic type designation is adenocarcinoma in situ and pT designation is pTis. Which has priority? Is the case reportable? | The case is reportable because carcinoma in situ is stated. Carcinoma in situ has higher priority than severe dysplasia or high grade dysplasia. Per AJCC 6th edition colon chapter, the terms "high grade dysplasia" or "severe dysplasia" may be synonymous with carcinoma in situ. Because the pathologist gave carcinoma in situ information within the CAP, (s)he is apparently defining the dysplasia as in situ carcinoma. |

20100072 | Histology/Reportability--Heme & Lymphoid Neoplasms: Is a diagnosis of follicular lymphoma in situ of the gallbladder reportable for 2010? See Discussion. | Coding the histology to 9690 [Follicular lymphoma] with a behavior of 2 [in situ] causes many edits including SEER and CS edits to fail. According to the chief of pathology, this is a recently identified pathologic entity. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Currently, lymphoma in situ is not reportable. It is true that this is a recently identified pathologic entity. Our experts say that there is still some controversy to be ironed out regarding the criteria for identifying an in situ lymphoma. Their recommendation was to wait until clear guidelines had been established for the pathologists before we start collection of in situ lymphomas. We anticipate collecting these entities in the future.

20100071 | Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How many primaries are accessioned for a patient diagnosed in February 2010 with a plasmacytoma of the frontal skull followed by a diagnosis of smoldering myeloma by bone marrow biopsy? See Discussion. | The patient had a diagnosis of solitary plasmacytoma of the right frontal skull in 2/2010 that was totally resected (the cranial specimen final diagnosis was plasmacytoma). The patient received radiation. While undergoing radiation, the patient was seen by a medical oncologist who did a bone marrow biopsy that revealed 10-15% plasma cells, and was called smoldering myeloma. Watchful waiting was recommended. In 8/2010, the patient had multiple lytic lesions and began systemic treatment.
Per rule M15 and the Multiple primary calculator, 9731/3 [plasmacytoma] and 9732/3 [smoldering myeloma] is accessioned as two primaries. When the manual states, "Use the Hematopoietic Database to determine the primary site and histology when PH1-PH29 do not apply," does this mean to use the calculator not the database itself? By the old rules this was one primary. Did this change for cases diagnosed 1/1/10 and later? Which M rule is the correct rule to apply? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
The smoldering myeloma is a second primary per Rule M10. Accession as multiple primaries because this case was originally diagnosed as a chronic neoplasm (plasmacytoma)phase and there was a second diagnosis of an acute neoplasm (multiple myeloma) more than 21 days after chronic diagnosis. See note 1 which indicates, "This is a change from previous rules." Note that the MP rules and the MP calculator in the Heme DB agree.
When the rules tell you to go to the DB to determine the histology and primary site, you use the DB information. (Don't forget to check the Abstractor Notes). The multiple primaries calculator is used to determine the number of primaries to abstract. Always use the M rules before using the MP calculator.

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.
