20130206 | Primary site--Heme & Lymphoid Neoplasms: What rule applies to code a primary site for a peripheral blood diagnosis of marginal zone lymphoma that has a positive flow cytometry/FISH analysis when no biopsies are performed, scans show no evidence of disease, exam indicates no lymph nodes are palpable and the physician's clinical diagnosis "marginal zone lymphoma, unspecified site, stage 1"? See Discussion. | PE: No palpable lymph nodes.
PET scan: No spleen or lymph node uptake; no uptake anywhere in the body.
Peripheral blood and flow cytometry/FISH analysis diagnosis: Marginal zone lymphoma.
No bone marrow or biopsy of any lymph nodes done. Doctor states "marginal zone lymphoma, unspecified site, stage 1." |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule PH27, code the primary site to C809 [unknown primary]. According to Rule PH27 one is to code the primary site to unknown primary site C809 when there is no evidence of lymphoma in lymph nodes AND the physician documents in the medical record that he/she suspects that the lymphoma originates in an organ(s) OR multiple organ involvement without any nodal involvement.
If further workup is done and a primary site is determined, update the primary site for this case.

20130181 | Multiple Primaries--Heme & Lymphoid Neoplasms: Should Rule M4 or the Heme DB be used to determine whether diffuse large B-cell lymphoma of the large intestine and peripheral T-cell lymphoma of the bone marrow represents one or two primaries? See Discussion. | The Heme DB identifies these as new primaries:
10/12/12 Large intestine, biopsy: Diffuse large B-cell lymphoma.
10/12/12 Bone marrow biopsy: Peripheral T-cell lymphoma. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule M15, accession two primaries. According to Rule M15, use the multiple primaries calculator to determine the number of primaries for all cases that do not meet the criteria of M1-M14. Per the calculator, this scenario represents two primaries.
Assuming the only area of involvement is the large intestine, code the histology to 9680/3 [diffuse Large B-Cell Lymphoma] and per Rule PH24 code the primary site to C189 [colon, NOS]. According to PH24, one is to code the primary site to the organ when lymphoma is present only in an organ.
Rule PH26 applies to the second primary. Assuming the only area of involvement is the bone marrow, code the histology to 9702/3 [peripheral T-cell lymphoma] and code the primary site to C421 [bone marrow]. According to PH26, one is to code the primary site to bone marrow (C421) when lymphoma is present only in the bone marrow.
Rule M4 does not apply for this case. Rule M4 applied when you have two or more types of non-Hodgkin lymphoma in the same anatomic location. That is not the case in this scenario.

20130192 | MP/H Rules/Histology--Pleura: How is histology coded when the pathology report final diagnosis is "malignant neoplasm, compatible with malignant mesothelioma" if the COMMENT section of the pathology report indicates the tumor has a mixed epithelial and sarcomatoid pattern? See Discussion. | This case was discussed with a pathologist who feels the correct histology should be biphasic mesothelioma (9053/3) because there are both epithelial and sarcomatoid components to this tumor. However, applying the current MP/H Rules, the histology is coded to 9050/3 (mesothelioma, NOS) because the term "pattern" cannot be used to code a more specific histologic type for invasive tumors. If this truly is a biphasic mesothelioma, that data is lost for researchers because the current MP/H Rules fail to capture this information. Should the term pattern be used to code the more specific histology in this case? | Code the histology to malignant mesothelioma, NOS [9050/3]. Apply the MP/H Rules as written until they are revised. The word "pattern" and other terms will be reconsidered for the next iteration of the rules. | 2013 |

20130070 | Reportability--Is "intraductal papillary mucinous neoplasm with low grade dysplasia" (also called IPMN adenoma) reportable? See Discussion. |
According to the ICD-O-3, the histology for IPMN adenoma is 8453/0 is non-reportable. However, per SINQ 20021099, this is reportable. |
Intraductal papillary mucinous neoplasm (IPMN) of the pancreas with low grade dysplasia, also referred to as IPMN adenoma, is not reportable. IPMN of the pancreas is reportable when stated as "IPMN with high-grade dysplasia," or "IPMN with an associated invasive carcinoma," or "IPMN with an associated in situ carcinoma." The case in SINQ 20021099 is stated to have "multifocal high grade dysplasia (so-called borderline tumor and carcinoma in-situ)" and is reportable because there is an explicit statement of carcinoma in situ, not because of the reference to the presence of high grade dysplasia. It is coded 8453/2 [Intraductal papillary-mucinous carcinoma, non-invasive]. |

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. |

20130170 | MP/H Rules/Histology--Breast: What is the histology code for "invasive carcinoma of the breast, no special type" as the final diagnosis on a pathology report? See Discussion. |
Recently pathology reports for breast primaries are no longer listing invasive ductal carcinoma as the histology on many cases if the treating physician calls the cancer an invasive ductal carcinoma. The pathology report (final diagnosis and synopsis) state this is invasive carcinoma, no special type.
Upon inquiry to the pathology department, the response received stated, In 2012, the WHO got rid of ductal carcinoma as a specific type. So what would have been called Invasive ductal carcinoma, Not Otherwise Specified (NOS), is now being called Invasive carcinoma, No Special Type (NST). In the new WHO classification, lobular, tubular, cribriform, mucinous, etc. are the special types. But ductal is gone.
Is this a change in terminology? Should these cases be coded as 8500/3 [ductal carcinoma, NOS] or 8010/3 [carcinoma, NOS]? |
Code the histology to ductal carcinoma, NOS [8500/3] for a pathology report with a final diagnosis of "invasive carcinoma, no special type." Do not code the histology to carcinoma, NOS [8010/3].
The 4th Edition of the WHO Classification of Tumors of the Breast refers to invasive ductal carcinoma as invasive carcinoma, no special type. The ICD-O-3 code remains the same as invasive duct carcinoma [8500/3]. The next revision to the MP/H Solid Tumor Rules will clarify this issue. |

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:

20130107 | Histology--Heme & Lymphoid Neoplasms: How is the histology coded for a diagnosis of polycythemia vera with myeloproliferative syndrome? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9950/3 [polycythemia vera], the more specific histology, per Rule PH29. Myeloproliferative syndrome is a non-specific (NOS) histology and polycythemia vera is a specific type of myeloproliferative disease.

20130222 | MP/H Rules/Histology--Bladder: How is the histology coded for a single bladder tumor showing invasive urothelial carcinoma with extensive divergent differentiation including small cell carcinoma, micropapillary carcinoma, and squamous cell carcinoma features? See Discussion. | MP/H rules seem to lead to Rule H8 which indicates that one use the numerically higher ICD-O-3 code. If one applies Rule H8, the histology is coded to 8131/3 [micropapillary urothelial carcinoma]. That would ignore the small cell carcinoma, which seems prognostically more significant. | Code the histology to 8045/3 [mixed small cell carcinoma], a combination of small cell with other types of carcinoma. There is currently no rule in the urinary site MP/H Rules for this combination of histologies. This will be included in the next revision of the MP/H Rules. | 2013 |

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." |
