20100113 Reportability--Heme & Lymphoid Neoplasms: Is hemophagocytic lymphohistiocytosis reportable?

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

No. This is not a reportable hematologic condition. When you do not find a hematologic or lymphoid condition listed in the Heme DB, it is not reportable. Hemophagocytic lymphohistiocytosis is an uncommon hematologic disorder. The patient usually presents with fever, splenomegaly, and jaundice. Laboratory findings are lymphocytosis and histiocytosis. Pathology findings are hemophagocytosis.

Appendix F lists this term as non-reportable.

20100098 Primary site/Histology--Heme & Lymphoid Neoplasms: How are these fields coded for a 2008 diagnosis of small B cell leukemia, most consistent with mantle cell leukemia that only involved the bone marrow? See Discussion. A bone marrow biopsy was done on 6/18/2008 and showed only small B cell leukemia, most consistent with mantle cell leukemia. ICD-O-3 does not list a histology code for small B cell leukemia or mantle cell leukemia.

Code the histology to 9673/3 [mantle cell lymphoma] and the primary site to C421 [bone marrow].

Mantle cell lymphoma can present in a leukemic phase. The only code available is for mantle cell lymphoma and the only primary site that could be coded would be bone marrow.

20100053 Primary site--Heme & Lymphoid Neoplasms: How is primary site coded for a myeloid sarcoma (granulocytic sarcoma) arising in the chest wall in a patient that has a negative bone marrow biopsy? See Discussion.

Patient was diagnosed with Myeloid Sarcoma (granulocytic sarcoma) by chest wall biopsy. This is an extramedullary manifestation of acute leukemia and is not in the bone marrow (bone marrow is negative).

How should primary site be coded? The Heme DB states that almost any part of the body can be involved. It also states to not code primary site to C421. In this case the only involvement is the chest wall [C493]. However, use of the primary site code C493 triggers an edit error questioning this site/histology combination. If the primary site is coded to C421 [bone marrow], there is no edit error. Please explain the site code and rationale.

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

Unless there are scans showing involvement of a lymph node or tissue other than the chest wall, the histology should be coded myeloid sarcoma [9930/3] and the primary site to C493 [soft tissue of chest wall]. Per Rule PH 30, use the Heme DB to determine primary site and histology when rules PH1-PH29 to not apply. Override the edit.

Per the Abstractor Notes section in Heme DB, for myeloid sarcoma [9930/3] the most frequently affected sites are skin, lymph nodes, gastrointestinal tract, soft tissue, and testis.

20100036 Behavior--Lung: Can an in situ behavior code be used for a bronchioalveolar carcinoma of the lung when the pathologist appears to use the term bronchioalveolar to describe an in situ pattern of growth exhibited by an adenocarcinoma? Is the use of the term "pattern" in this situation indicative of in situ tumor? See Discussion.

In ICD-O-3, bronchioloalveolar adenocarcinoma is described only by behavior code 3 (invasive). Would the behavior be coded as in situ for the following cases?

Example 1: Left lower lobe, partial resection shows bronchioloalveolar carcinoma with focal areas of fibrosis (see comment). Comment: Although the possibility that these areas represent stromal invasion can not be excluded, we favor the interpretation that these areas do not represent true invasion. Synoptic summary: Minimal pathologic stage: Local Extent.

Example 2: Lung tumor described as adenocarcinoma, predominantly bronchoalveolar pattern. For most sites, the term pattern is used only for in situ cancer and is not a specific term used for invasive tumors. Is the use of the term "pattern" in this situation indicative of in situ tumor?

Code the behavior indicated in the pathology report. If the pathologist states the bronchioloalveolar carcinoma is in situ, apply the ICD-O-3 matrix rule and assign 8250/2. Otherwise, code 8250/3. Do not use the term "pattern" to infer in situ behavior.

Code behavior /3 for both examples based on information provided.

Histology--Heme & Lymphoid Neoplasms: How is histology to be coded for acute lymphoblastic leukemia (ALL) and/or precursor B acute lymphoblastic leukemia (Pre-B ALL) for cases diagnosed 2010 and later? The Heme Database has two histology codes for this disease, both 9811/3 and 9836/3, which is the correct histology code?

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

Code histology to 9811/3 [B lymphoblastic leukemia/lymphoma, NOS].

See the Abstractor Notes section in the Heme DB, when determining how to code histology for a case. It indicates the code 9811/3 is effective for cases diagnosed 2010 and forward. The 9836/3 is listed as obsolete and refers you to code 9811/3. Make sure to check for a specific subtype of B lymphoblastic leukemia/lymphoma [9812/3 - 9818/3] before assigning the NOS code [9811/3].

20100112 Primary site--Heme & Lymphoid Neoplasms: Is C448 [overlapping lesion of skin] or C449 [skin, NOS] the appropriate site code for a 2008 diagnosis of mycosis fungoides involving over 40 percent of the skin surface, including both upper and lower extremities and trunk? Code the primary site to C449 [skin, NOS]. The code C448 should be used when there is a single overlapping lesion that includes all the disease. The patient has extensive skin coverage involving multiple skin subsites (upper and lower extremities and the trunk), but it is unlikely there is ONE plaque (one lesion) overlapping all these different skin subsites. The disease has more likely presented as multiple plaques (lesions) in these different areas. 2010

Reportability--Esophagus/Stomach: Are the terms "high grade dysplasia" and "severe dysplasia" synonymous with in situ for tumors in the gastrointestinal tract? See Discussion.

SINQ 20000245 states that high grade or severe dysplasia in not synonymous with in situ disease. However, per page 109 in the 7th edition of AJCC Cancer Staging Manual, high grade dysplasia is the only term listed under Tis. A note on that page explains that "high-grade dysplasia includes all noninvasive neoplastic epithelia that was formerly called carcinoma in situ, a diagnosis that is no longer used for columnar mucosae anywhere in the gastrointestinal tract."

There has been considerable pressure from registrars at larger reporting facilities to re-address this issue. The pathologists at these facilities state that they are correctly documenting the presence of in situ disease when they use the term high grade dysplasia for gastrointestinal tract tumors. In their opinion, it is not necessary to add the term in situ in parentheses following the use of the term high grade dysplasia to clarify the behavior of these lesions in their pathology reports. If the term "carcinoma in situ" is no longer being used by many pathologists for sites in the gastrointestinal tract, won't this lead to underreporting of in situ disease for these sites unless the reportability guidelines are changed?

For cancer reporting purposes, the terms "high grade dysplasia" and "severe dysplasia" are not synonymous with in situ for tumors in the gastrointestinal tract. These cases are only reportable when the pathologist documents carcinoma in situ or intraepithelial neoplasia grade III, or when the registry includes in their policies and procedures the pathologist's statement that he/she uses HGD to mean the same as CIS.

Reportability laws are customarily based on ICD-O. Because "high grade dysplasia" and "severe dysplasia" are not designated as in situ in the ICD-O, there is no legal authority to report these cases in most states.

NAACCR is reviewing this issue. See #5 on page 11 of the December 1, 2013 NAACCR Implementation document, http://www.naaccr.org/LinkClick.aspx?fileticket=u7d3sB71t5w%3d&tabid=126&mid=466

20100009 MP/H Rules/Multiple primaries--Bladder: Is a new primary accessioned for a 2009 diagnosis of transitional cell carcinoma of the bladder when the patient has a history of invasive bladder cancer NOS diagnosed? See Discussion.

A patient has a history of invasive bladder cancer diagnosed several years ago in another state. In 2009, the patient was admitted and found to have a positive biopsy for transitional cell carcinoma of the bladder.

Is this a new primary because the histology of the previous bladder cancer is unknown? When the histology of a previously diagnosed bladder cancer is unknown, should we assume the previous tumor was urothelial carcinoma?

 For cases diagnosed 2007 or later, apply rule M6. The 2009 diagnosis is not a new primary. Transitional cell carcinomas account for more than 90% of bladder cancers. If the patient actually had a rare small cell, squamous cell, or adenocarcinoma of the bladder in the past, it is highly likely it would be mentioned in the medical record. 2010

Histology--Heme & Lymphoid Neoplasms: How is this field coded for a case described as follicular lymphoma, grade 3a/3 [9698/3], with focal areas of diffuse large B cell lymphoma [9680/3] (approximately 10%)? Does the term "focal" have the same significance in Heme cases as it does for solid tumors? See Discussion.

Per rule PH11, "Code the primary site to the site of origin (lymph node region(s), tissue, or organ) and code the histology diffuse large B-cell lymphoma (DLBCL) (9680/3) when DLBCL and any other non-Hodgkin lymphoma are present in the same lymph node(s), lymph node region(s), organ(s), tissue(s) or bone marrow."

Should the focal diffuse large B cell lymphoma be ignored in this case and rule PH11 not be applied? To apply rule PH11, does the follicular lymphoma have to be NOS [9690/3] or does PH11 include all grades of follicular lymphoma [9695/3, 9691/3, 9698/3]?

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

First, you need to determine how many primaries are to be accessioned. Per Rule M4, abstract 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).

Code the histology to 9680/3 [Diffuse large B cell lymphoma] per rule PH11 when DLBCL and any other non-Hodgkin lymphoma are present in the same lymph node(s), lymph node region(s), organ(s), tissue(s) or bone marrow. Follicular lymphoma (FL), which is a non-Hodgkin lymphoma, includes FL, NOS, FL grade 1, FL grade 2 and FL grade 3.

Focal, foci, and focus are not used in the hematopoietic rules, meaning that you DO NOT ignore histology terms described as focal, foci, or focus.

20100088 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient has 2005 diagnosis of multiple myeloma diagnosed returns in 2010 with extramedullary plasmacytoma and a bone marrow biopsy showing plasma cell dyscrasia that is clinically stated to "consistent with a relapse of myeloma"? See Discussion.

Patient was diagnosed in 2005 with multiple myeloma and following stem cell transplant 2005 was in complete remission.

On 2/1/10 an excisional biopsy of a soft tissue right flank mass showed plasmacytoma. On 3/2/10 the bone marrow biopsy was stated to be consistent with plasma cell dyscrasia. An outside attending physician stated the bone marrow biopsy was consistent with a relapse of myeloma. There was no radiologic evidence of disease elsewhere as of Feb 2010, only the soft tissue right flank mass. Patient initially presented for post-op radiation to the right flank and was treated 3/29/10. On 8/6/10 a biopsy of a right perinephric mass was positive for plasmacytoma. Subsequent xray on 8/16/10 of the right tibia and fibula showed lytic lesion consistent with progression of myeloma.

Using the Hematopoietic Database, the plasmacytoma in 2/1/10 is a second primary. How do the rules apply to the perinephric soft tissue disease and right tibia lesion? Are they separate new primaries? Or is all of this simply a recurrence of the original 2005 diagnosis as the attending physician states?

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

Accession a single primary with the histology coded to 9732/2 [multiple myeloma]. The disease discovered in 2010 represents further advancement of former disease. Per the Abstractor Notes section in the Heme DB, it states that bone marrow involvement, lytic bone lesions, and bone tumor masses of plasma cells are common. Under the Recurrence and Metastases section in the Heme DB it further states that extramedullary (in tissue other than the bone) involvement is a generally a manifestation of advanced disease. This case is an example of such a situation.
