20130178 | Reportability--Heme & Lymphoid Neoplasms: Is refractory iron deficiency anemia reportable? | Per Appendix F, refractory iron deficiency anemia is not reportable. It is not a clonal disorder and, therefore, is not malignant. Refractory iron deficiency anemia is a condition that is unresponsive to oral iron treatment. | 2013 | |

20130161 | Primary Site--Heme & Lymphoid Neoplasms: Is the primary site coded to C779 or C421 for a bone marrow that is positive for B-cell acute lymphoblastic leukemia, the peripheral blood demonstrates leukemic involvement and the PET scan shows involvement of abdominal lymph nodes, spleen and throughout the bones? See Discussion. | 1/11/13 Bone marrow bx: B-cell acute lymphoblastic leukemia. Flow cytometry of peripheral blood shows leukemia involvement.
PET scan shows involvement of abdominal lymph nodes, spleen and throughout the bones. The patient has an elevated WBC, anemia and thrombocytopenia.
The answer to SINQ 20120047 (which is no longer visible in the system) said to code B lymphoblastic leukemia/lymphoma to bone marrow for primary site if there is bone marrow involvement. The Heme/Lymph Manual Rule PH7 says to code bone marrow as the primary site if bone marrow is the only site involved.
Following the manual, the primary site would be C779. However, according to the answer to SINQ 20120047, the primary site would be C421. Which is correct? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per the Heme DB, the histology B-cell acute lymphoblastic leukemia is synonymous with B lymphoblastic leukemia/lymphoma, NOS. Per Rule PH8, for a neoplasm that can manifest as either leukemia lymphoma or leukemia lymphoma, one is to code the primary site to the site of origin when lymph node(s) or lymph node region(s), tissue(s) or organs are involved. The Note 4 instruction states it is necessary to go to Module 7 (Rules PH18-PH27) to code the more specific primary site. In this case, use Rule PH22 to code primary site to C779 [lymph nodes, NOS] for the case you describe.
In this case, there is involvement of abdominal lymph nodes, spleen, bone marrow and bone. There is no indication of the primary site. Per the Heme DB, the most frequent sites of involvement for the lymphoma are bone and lymph nodes. This is a Stage IV lymphoma.
The now inactivated SINQ 20120047, stated that based on the sites of involvement, this histology could be coded as either leukemia or lymphoma. If the only involvement is the bone marrow, the site is coded to C421 [bone marrow]. The involvement of peripheral blood does not change the primary site because such involvement is part of the leukemic process.

20130176 | Reportability--Ovary: Is an adult granulosa cell tumor of the right adnexa reportable if the left adnexa, diaphragm and paratubal tissue are reported to be consistent with metastasis? See discussion. |
Per the pathology report: Right adnexa: adult granulosa cell tumor. Left adnexa: Foci of metastatic granulosa cell tumor in paratubal tissue. Diaphragm smears: consistent with metastatic granulosa cell tumor. Comment: The morphology and immunoprofile of the cellular aggregates in the paratubal soft tissue are consistent with metastatic granulosa cell tumor. |
Based on the information provided, this case of adult granulosa cell tumor is malignant and reportable. According to our expert pathologist consultant, "though granulosa cell tumor NOS/ adult NOS is 8620/1, the presence of peritoneal implants or metastases, and/or lymph node metastases indicates the tumor is malignant, and it should be coded /3."
Note that the presence of implants or metastases does not indicate malignancy in the case of low malignant potential ovarian epithelial tumors. Our path expert explains "in contrast, by convention the behavior of borderline/LMP ovarian epithelial tumors is determined by the ovarian primary, and is /1, even though there may be peritoneal implants/metastases, or metastatic disease in lymph nodes. The treatment may vary in these circumstances, but to my knowledge the decision as to the tumor designation remains based on the primary tumor." |

20130177 | MP/H Rules/Histology--Bladder: What rule and histology code apply when a TURB final diagnosis is small cell neuroendocrine carcinoma and high grade urothelial carcinoma? See Discussion. | The patient has a 6 cm tumor arising in posterior-lateral bladder extending to prostate, obliterates seminal vesicle, and invades pelvic wall.
TURB final diagnosis: Small cell neuroendocrine carcinoma. High grade urothelial carcinoma involves 10% of tumor.
Following the current MP/H single tumor rules, it appears Rule H8 applies. Per Rule H8, code the numerically higher code of 8120. By following this rule, it does not seem the histology code fairly represents this tumor. |
There is currently no rule in the urinary site MP/H Rules for this combination of histologies. The best option is to code the histology to 8045/3 [mixed small cell carcinoma], a combination of small cell with other types of carcinoma. The presence of small cell carcinoma drives the treatment decisions for this case.
This issue will be addressed in the next revision of the MP/H Rules. |

20130095 | Grade--Heme & Lymphoid Neoplasms: How is grade coded for acute lymphoblastic leukemia, NOS? See Discussion. | The Heme DB indicates histology code 9811/3 [B lymphoblastic leukemia/lymphoma] is the current histology code to use for the now obsolete term of acute lymphoblastic leukemia [9835/3]. The Heme DB entry for histology code 9835/3 states to "Code grade specified by pathologist. If no grade specified, code 9." The Heme DB entry for the current histology code, 9811/3, states to code the grade to 6 [B-cell]. Should grade be coded to 6 [B-cell] for all cases coded to histology code 9811/3? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the grade to 6 [B-cell] for all cases of 9811/3 [B lymphoblastic leukemia/lymphoma] per Rule G3 in the Heme Manual.
Acute lymphoblastic leukemia, NOS [9835/3] is an obsolete code and cannot be used for cases diagnosed 2010 and later. The Heme DB indicates the correct histology code is 9811/3 and grade 6 [B-cell] for cases diagnosed 2010 and later.
For cases of acute lymphoblastic lymphoma, NOS [9835/3] diagnosed prior to 2010, use the pathology report information to code the grade. Code the grade as 9 [unknown] if the pathology report does not specify the grade.

20130014 | Reportability--Heme & Lymphoid Neoplasms: Is Castleman disease reportable when diagnosed 2010 and later? | When checking Castleman disease in the Hematopoietic Database, the result is a reportable histology code 9738/3. However, per an online search, Castleman disease is a very rare disorder characterized by non-cancerous growths (tumors). | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Castleman disease, NOS, is not reportable for cases diagnosed 2010 and later. However, when Castleman disease is diagnosed in connection with large B-cell lymphoma [9738/3], it is reportable.

20130198 | MP/H Rules/Multiple primaries--Rectosigmoid: How many primaries are accessioned for a synchronous diagnosis of neuroendocrine carcinoma and a separate adenocarcinoma arising in a villous adenoma when both arise in the rectosigmoid junction? See Discussion. | Total colectomy showed neuroendocrine carcinoma of the rectosigmoid junction, as well as a separate adenocarcinoma arising in a villous adenoma of the rectosigmoid junction. Is this a single primary per Rule M13 (a frank adenocarcinoma and an adenocarcinoma in a polyp) or Rule M16 (adenocarcinoma and a more specific adenocarcinoma)? Or are these two primaries? | Accession two primaries per Rule M17, neuroendocrine carcinoma [8246/3] of the rectosigmoid junction [C199], and adenocarcinoma in a villous adenoma [8261/3] of the rectosigmoid junction [C199]. There are two tumors with ICD-O-3 histology codes that differ at the third number.
Rule M13 does not apply to neuroendocrine carcinoma. Rule M16 does not apply to this case because there are two specific histologies. |

20130012 | MP/H Rules/Multiple primaries--Urinary: If topography codes C681-C689 are not included in Urinary Multiple Primary Rule M8, would a subsequent renal pelvis papillary transitional cell carcinoma be a new primary? See Discussion. |
The patient had a papillary transitional cell carcinoma of the bladder and ureter diagnosed in 2010. The primary site was coded to C689 [urinary system, NOS]. The patient was diagnosed with a transitional cell carcinoma of the renal pelvis [C659] in 2012. In applying the MP/H rules to the 2012 diagnosis, rule M8 would be ignored because the primary site of the 2010 primary was coded to C689. The result is that M9 or M10 would be applied which indicates a new primary for the 2012 diagnosis. Should the 2012 renal pelvis carcinoma be a new primary? |
For cases diagnosed 2007 or later, accession a single primary, papillary transitional cell carcinoma of the bladder and ureter [C689, urinary system, NOS] diagnosed in 2010. The steps used to arrive at this decision are: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Urinary MP Rules because site specific rules exist for this primary. Start at the MULTIPLE TUMORS module, rule M3. The rules are intended to be reviewed in consecutive order within a module. This patient has urothelial tumors in two or more of the listed sites (bladder, ureter and renal pelvis) diagnosed within 3 years. When C689 is assigned because tumors of the bladder and tumors of the ureter were determined to be a single primary and the site of origin is not known (as in this example), rule M8 is applied when a subsequent tumor is diagnosed in one of the listed sites. However, if site C689 [urinary system, NOS] was assigned for other unknown urinary primary site situations, rule M8 would not be used. Rule M8 was written specifically for urothelial tumors in the renal pelvis, ureter, bladder and urethra. Paraurethral gland [C681] and overlapping lesions of urinary organs [C688] do not belong in rule M8. We will add this issue to the list of possible revisions for the next edition of the MP/H Rules. |

20130017 | Reportability--Heme & Lymphoid Neoplasms: Is reactive thrombocytosis reportable? See Discussion. |
The doctor's impression: "Thrombocytosis, mild without other obvious hematologic difficulty. I would be most suspicious for early iron deficiency related to her prior menometrorrhagia. Would limit initial evaluation to iron studies, review of peripheral smear, and hepatic profile." | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Reactive thrombocytosis is not reportable and is not an alternative name for essential thrombocythemia [9962/3].
Only the following are listed as alternate names for essential thrombocythemia in the Heme DB:

20130179 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries and what is the histology for each primary if a diffuse large B-cell lymphoma [9680/3] and a focus of splenic marginal zone lymphoma [9689/3] occur in a splenectomy specimen? See Discussion. | Patient presents with a huge mass in the spleen with direct extension to gastric fundus.
12/1/12 Splenectomy: Macroscopic nodules compatible with diffuse large B-cell lymphoma [9680/3]. Further, in the white pulp there are changes compatible with focus of splenic marginal zone lymphoma [9689/3].
Under the Transformations To section in the Heme DB, splenic marginal zone lymphoma transforms to diffuse large B-cell lymphoma. |
Per Rule M4, this is a single primary. According to Rule M4, one is to 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).
Per Rule PH11, code the histology to 9680/3 [diffuse large B-cell lymphoma] and the primary site to C422 [spleen]. According to PH11, one is to code the primary site to the site of origin, lymph node(s), lymph node region(s), tissue(s) or organ(s) and histology to 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. |
