Reportability--Heme & Lymphoid Neoplasms: Is the term "thrombocytopenia" equivalent to the term "refractory thrombocytopenia" and should be a subsequent primary if it follows a treated diagnosis of pancreatic cancer?

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

Thrombocytopenia NOS is not a reportable diagnosis per Appendix F. Thrombocytopenia and Refractory Thrombocytopenia are not the same disease.

Thrombocytopenia is caused by a decreased number of platelets in the blood. Non-malignant causes include disseminated intravascular coagulation (DIC), drug-induced non-immune thrombocytopenia, drug-induced immune thrombocytopenia, hypersplenism, immune thrombocytopenic purpura (ITP), thrombotic thrombocytopenic purpura, and infections of the bone marrow.

20100107 MP/H Rules/Histology--Kidney, renal pelvis: How is histology coded for a tumor described as "renal cell carcinoma, clear cell with rhabdoid features"? See Discussion.

Is the statement "with __ features" indicative of a specific type of renal cell carcinoma (that is not represented by a specific histology code) or a second histologic type? Per ICD-O, "malignant rhabdoid tumor" is coded 8963/3. "Rhabdoid" is not listed in Table 1 in the MP/H rules as a specific type of renal cell carcinoma.

Rhabdoid features occur in about 5% of all renal cell cancers and indicate a more aggressive tumor. Per WHO, these tumors comprise approximately 2% of all pediatric tumors with a median diagnosis age of 1-2 years old. This diagnosis is highly suspect in patients over age 3. Most previously reported rhabdoid tumors over age 5 have subsequently proven to be renal medullary carcinomas.

For cases diagnosed 2007 or later, if the patient in this case is a child, apply Kidney Rule H7 and code histology to 8963/3 [malignant rhaboid tumor]. Otherwise, we strongly suggest you consult with the pathologist to determine if this is truly a rhabdoid rather than a medullary tumor.

20100062 MP/H Rules/Histology--Lung: How is histology coded when there is a lung biopsy compatible with non-small cell carcinoma and regional lymph node biopsies compatible with adenocarcinoma? See Discussion. Which histology has priority when the pathology specimens reveal different histologies in the primary site and the regional lymph node? Do we assume the lung biopsy is the most representative tumor specimen because it is from the primary site and code to 8046 [non-small cell carcinoma] or should we use rule H5 and code to 8140 [adenocarcinoma, NOS] because adenocarcinoma is a more specific histology than non-small cell carcinoma? For cases diagnosed 2007 or later, code histology based on a pathology report from the primary site whenever possible. Code histology to 8046/3 [non-small cell carcinoma] for the case example provided. 2010
20100069 Primary site--Heme & Lymphoid Neoplasms: How is this field coded when a 5/26/10 colonoscopy reveals ulcers in the cecum, ascending, transverse, descending, and sigmoid colon and, the final diagnosis on the pathology report is post-transplant lymphoproliferative disorder [9971/3]?

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

Code the primary site to C189 [Colon, NOS] per Rule PH1.

Code the primary site to C189 [Colon, NOS] and not C188 [Colon, overlapping lesion] because there are multiple ulcers in different segments of the colon. The .8 code is used only for a single lesion that overlaps subsites.

20100007 MP/H Rules/Histology--Melanoma: Regarding SINQ #20081044, when would you apply Rule H6 rather than Rule H5 for a cutaneous malignant melanoma given that you normally always have a specific cell type mentioned? For cases diagnosed 2007 or later, Rule H6 is used when you do not have a specific cell type other than regressing melanoma, or malignant melanoma, regressing. If you have regressing melanoma with a specific cell type, apply rule H5. 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."

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.

20100086 Multiple primaries/Primary site/Histology--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient is diagnosed with mycosis fungoides in February 2010 and in May 2010 is diagnosed with peripheral T-cell lymphoma consistent with CD 30+ large cell transformation of mycosis fungoides? See Discussion Patient was diagnosed with mycosis fungoides on 2/10/2010. On 5/11/2010 the patient underwent lymph node biopsies lymph nodes that were diagnosed as peripheral Tcell lymphoma consistent with CD 30+ large cell transformation of mycosis fungoides. There is no data on the ALK protein.

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

Accession two primaries per Rule M15 which instructs you to use the Multiple Primaries Calculator to determine the number of reportable primaries. The result is that mycosis fungoides [9700/3] and peripheral T-cell lymphoma [9702/3] represents two primaries.

20100058 Grade: Can the nuclear grade value be coded in the grade field for any site, or is it restricted to sites where it is specifically listed as an option in the coding manual, i.e., breast, kidney, urinary sites, etc.? There is no restriction on sites for which nuclear grade can be coded in the grade field. If both differentiation and nuclear grade are specified, differentiation takes priority. 2010

MP/H Rules/Multiple primaries--Kidney, renal pelvis: In a patient who was never disease free because of multiple recurrences of invasive transitional cell carcinoma of the bladder originally diagnosed in 2004, is an invasive high grade urothelial carcinoma of the renal pelvis diagnosed in 2010 a new primary? See Discussion.

Patient has invasive TCC of the bladder diagnosed in 2004, and has never been disease free.

In 2/18/10 a left renal pelvis wash showed urothelial carcinoma, high grade.

On 4/7/10 a nephroureterectomy revealed high grade urothelial carcinoma with sarcomatous and squamous differentiation invading through pelvic wall and perihilar soft tissue.

Is this a new renal pelvis primary?

For cases diagnosed 2007 or later, the renal pelvis is a new primary per rule M7. M7 will be better explained in the revised MP/H rules, but the rationale is that no field effect was present for more than 3 years. Although the bladder CA continued to recur, there were no other organs involved until 2010. M7 is intended to make the renal pelvis a new primary because there was no field effect (no organs other than bladder involved) for more than 3 years.
