20130037 Histology--Heme & Lymphoid Neoplasms: How is the histology coded for a "cutaneous diffuse large B-cell lymphoma, leg type" that has been verified as a valid diagnosis with prognostic factors including age and number of lesions on the legs?

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

Code this histology to 9680/3 [diffuse large B-cell lymphoma]. Primary cutaneous DLBCL, leg type, is listed as an Alternate Name for DLBCL per the Heme DB.

20130005 Reportability--Brain and CNS: Are spinal schwannomas and neurofibromas reportable or non-reportable? The most accurate and most current instruction is to report these spinal tumors when they arise within the spinal dura or spinal nerve roots, or when they are stated to be "intradural" or "of the nerve root." Do not report these tumors when they arise in the peripheral nerves. The peripheral nerves are the portion of nerve extending beyond the spinal dura. 2013
20130080 Primary site/Histology--Heme & Lymphoid Neoplasms: How are the primary site and histology coded when a right neck mass and spinal mass both show B-cell lymphoma, favor Burkitt lymphoma? See Discussion.

2/5/11 Right neck swelling. Biopsy of mass B-cell lymphoma, favor Burkitt lymphoma.

7/5/11 Hemi-laminectomy, L2-L5 spinal mass: Malignant lymphoma, B-cell phenotype, favor Burkitt lymphoma.

Should the primary site be C779? Is the correct histology Burkitt lymphoma [9687/3] or malignant lymphoma, diffuse large B-cell [9680/3]?

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

Code the primary site to C779 [lymph nodes] per Rule PH22 and the histology to 9591/3 [B-cell lymphoma, NOS].

Code the primary site to C779 [lymph nodes, NOS] when lymphoma is present in an organ and lymph nodes that are not regional for that organ and the origin cannot be determined even after consulting the physician. The patient has involvement of a lumbar spine mass and cervical lymph nodes. Cervical lymph nodes are not regional to the lumbar area of the spine.

Do not use ambiguous terminology to code histology for hematopoietic neoplasms. "Favor" is ambiguous terminology. Therefore, the histology must be coded to B-cell lymphoma and not to diagnosis which is "favored" (Burkitt lymphoma). Remember that ambiguous terminology is only used to determine case reportability, not to code histology for hematopoietic neoplasms.

Primary Site--Heme & Lymphoid Neoplasms: How is the primary site coded for a B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma when a biopsy of the paraspinal muscle and epidural tissue is positive, but there is no indication of lymph node involvement in the chart?

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

Code the primary site to soft tissue of the back, NOS [C496] per Rule PH24 and the Abstractor Notes in the Heme DB for B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma.

Code the primary site to the organ when lymphoma is present only in an organ. The lesion is described as epidural (tissue surrounding the dura) and involving paraspinal muscle, NOS. Both are connective or other soft tissues of the trunk, NOS [C496].

B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma is a synonym for DLBCL 9680/3. When there is no primary site listed in the Heme DB, go to the Abstractor Notes. In the Abstractor Notes section it states that patients present with lymphadenopathy OR mass lesions in extranodal sites.

20130009 Grade--Pancreas: Can the grade be coded when a biopsy is taken from the part of a primary tumor that has contiguously extended into an adjacent organ or structure? See Discussion. The grade rule states to code grade from tissue removed from the primary tumor only, never from a metastatic site or a site of recurrence. There is no mention of whether the grade can be coded if only the contiguous site of involvement is biopsied when a single tumor directly extends to an adjacent tissue or organ. For example, is grade coded to 2 when a pancreatic tumor extends into the duodenum, and the duodenal biopsy confirms moderately differentiated adenocarcinoma consistent with a pancreatic primary? Or does the primary organ/site have to be biopsied in order to be able to code grade?

For one tumor involving a contiguous site, when there is no tissue specimen available from the primary site, you may code the grade based on the tissue from the tumor in the contiguous site.

This instruction is included in the upcoming grade instruction document.

20130119 Reportability--Heme & Lymphoid Neoplasms: Would this case be reportable? Patient with a myelodysplastic syndrome secondary to a copper deficiency. Myelodysplastic syndrome is a reportable disease. Document in the text that the MDS was due to a copper deficiency. 2013
20130121 Reportability--Heme & Lymphoid Neoplasms: Is "early essential thrombocythemia" reportable? See Discussion. The bone marrow biopsy diagnosis was, "Combined bone marrow morphologic, flow cytometric, immunohistochemical, molecular and cytogenetic findings are most consistent with early or evolving essential thrombocythemia with low level JAK2 V617F mutation documented on molecular testing." The physician is calling this a benign process. Is this reportable as essential thrombocythemia? Are the terms early or evolving ignored? Does the presence of a JAK2 mutation make this reportable? Without JAK2 testing is this case reportable?

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

Yes, this is a reportable case. The histology is coded to 9962/3 [essential thrombocythemia]. The positive JAK2 mutation testing and bone marrow biopsy results taken together support the diagnosis of essential thrombocythemia in this case.

In the Abstractor Notes section of the Heme DB, it indicates that only 50-60 percent of patients with essential thrombocythemia will have a positive JAK2 mutation. A diagnosis of essential thrombocythemia can still be made in the absence of a JAK2 mutation. For example, if the bone marrow biopsy final diagnosis or a physician's clinical diagnosis is essential thrombocythemia, despite a negative JAK2 mutation test, the neoplasm is still reportable.

20130032 Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for plasma cell myeloma with radiologic evidence of multiple lytic lesions? See Discussion.

Patient complained of pain in the right side and back right upper flank area. CT shows an anterior mediastinal mass and abnormal appearance of skeleton. CXR: Age indeterminate T8 compression fracture. CT chest: abnormal appearance of skeleton. Correlate clinically for myeloma or mets. Acute T5 or T8 compression fractures. Anterior mediastinal mass which may represent thymoma, lymph nodes or metastases. 03/22/12 Metastatic Series: Nonspecific hypodensities in pelvis, left hip and right acromion. Possibility of myeloma can't be totally excluded. Bone marrow right post iliac crest core biopsy, clot section and aspirate: plasma cell myeloma.

Should the primary site be coded to the bone marrow because the diagnosis of plasma cell myeloma was supported by radiologic evidence of multiple lytic lesions? The bone marrow biopsy confirmed the radiology reports.

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 the Heme DB and Rule PH30. The Primary Site(s) section in the Heme DB indicates the primary site for plasma cell myeloma is C421 [bone marrow].

The Primary Site Coding Instructions in the Heme Manual (Rule 1) states that when a specific code is listed under the Primary Site(s) section of the Heme DB it is the only primary site code that can be assigned for that leukemia, myelodysplastic syndrome or myeloproliferative syndrome. Applying the PH Rules will result in the same answer for primary site, bone marrow [C421].

20130052 Histology--Heme & Lymphoid Neoplasms: How is the histology coded if a biopsy final diagnosis is diffuse large B-cell lymphoma but the physician's final diagnosis favored anaplastic large cell lymphoma? See Discussion. Patient has diffuse intrathoracic, intraabdominal and pelvic lymphadenopathy. An inguinal lymph node biopsy showed diffuse large B-cell lymphoma. The physician's final diagnosis favored anaplastic large cell lymphoma, but wanted to confirm this with FISH. The patient clinically deteriorated so the FISH studies were not done. Which histology is coded?

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

The histology should be coded as diffuse large B-cell lymphoma [9680/3]. The biopsy pathology report definitively diagnosed DLBCL. The physician's diagnosis cannot be used because it is an ambiguous diagnosis only, "favored anaplastic large cell lymphoma." "Favor" is an ambiguous term.
