20110043 MP/H Rules/Histology--Breast: Which specimen should be used to code histology when a core biopsy revealed an unknown sized DCIS, comedo type and the partial mastectomy specimen showed only a 2mm focus of DCIS, solid pattern? See Discussion.

Should the histology be coded from the needle core biopsy or the partial mastectomy specimen? Patient had a needle core biopsy that revealed DCIS, comedo type, cribriform pattern, no tumor size given. Subsequently, the patient had a partial mastectomy which revealed DCIS, noncomedo type, solid pattern, largest focus of DCIS was 0.2cm.

Should the histology code be 8501/2 or 8230/2? The microscopic description on the partial mastectomy says that the previous core needle biopsy site revealed several foci of DCIS.

 Code the histology from the most representative specimen (the specimen with the MOST tumor tissue). Compare the size of tumor in the two specimens. If the tumor size is not available for both procedural specimens, code histology from the mastectomy specimen rather than the needle biopsy specimen. 2011
20110051 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when bilateral breasts are involved with MALT lymphoma and the bone marrow is negative?

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

Per Rule M2, this is a single primary because there is a single histology mentioned. The histology is coded to 9699/3 [MALT lymphoma]. Code the primary site to C509 [breast] per Rule PH24 which states to code the primary site to the organ when lymphoma is present only in an organ.

Unless your software has edits that prevent coding laterality for lymphomas, code the laterality as bilateral. Up to half of extranodal, extragastric MALT lymphomas occur in multiple sites, particularly in paired sites (breast is an example).

20110134 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted, and what rule applies, when the patient has a 1999 diagnosis of Burkitt high grade B-cell lymphoma and was diagnosed in 2011 with diffuse large B-cell lymphoma? See Discussion Patient diagnosed in 1999 with Burkitt high-grade B cell lymphoma of the thyroid gland and cervical nodes. The patient was treated with a thyroidectomy and chemotherapy. A 2011 biopsy of the parotid gland is positive for diffuse large B cell lymphoma. The pathologist reviewed the 1999 and 2011 pathology reports and stated this is one primary.

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

This case should be accessioned as two primaries per Rule M15. Rule M15 instructs one 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. Code the histology for the 1999 primary to 9687/3 [Burkitt high grade B cell lymphoma] and code primary site to C739 [thyroid.] Code the second primary to 9680/3 [diffuse large B-cell lymphoma] with primary site coded to C079 [parotid gland] per Rule PH24 which instructs one to code the to the when lymphoma is present only in an .

Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when a patient is diagnosed with NHL, large B-cell lymphoma in 3/2010 followed by a "recurrence of previously diagnosed" NHL per a 12/2010 liver biopsy? See Discussion.

Are there timing rules related to the comparison of slides from a subsequent hematopoietic primary diagnosis to the slides from the original hematopoietic primary diagnosis that impact the number or primaries reported?

For example, how many primaries are reported for a patient was diagnosed in 3/2010 with large B-cell lymphoma who underwent 7 rounds of chemo. Per 10/2010 PET scan, there was no evidence of disease. In 12/2010 a liver biopsy revealed, "features consistent with recurrence of previously diagnosed non-Hodgkin lymphoma." The pathologist did not compare slides to the original, but several immunoperoxidase stains were done to obtain the final diagnosis in 12/2010.

Does timing or comparison to the original slides matter for Heme & Lymphoid Neoplasms? Is a comparison of slides needed as required for solid tumor "recurrences"?

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

This case should be accessioned as one primary per Rule M15, 9680/3 [diffuse large B-cell lymphoma]. Per Rule M15 one is 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 12/2010 liver diagnosis of NHL, NOS [9591/3] is the same primary per the Multiple Primaries Calculator.

There are no timing rules for lymphoma other than rules M8-M13 which deal with the timing of chronic and acute diagnoses.

20110130 MP/H Rules/Multiple primaries--Lung: Should a July 2011 left lower lobe mass with adenocarcinoma be accessioned as an additional primary per Rule M7 or as the same primary per Rule M12 if it is diagnosed subsequent to a September 2010 right upper lobe/right middle lobe lobectomy with clear cell adenocarcinoma in one nodule and adenocarcinoma in another nodule? See Discussion.

09/2010: RUL/RML lobectomy: Two separate nodules. One nodule showed clear cell adenocarcinoma, and the other showed adenocarcinoma (NOS). Potential brain metastasis per scan. Patient also received chemotherapy. These are two separate primaries per rule M11.

07/2011: New LLL mass + satellite nodule, biopsy of LLL mass compatible with adenocarcinoma (NOS).

Is the 07/2011 an additional new primary per rule M7? Or is it the same primary as the 09/2010 adenocarcinoma per rule M12?

For cases diagnosed 2007 or later: The 2011 diagnosis of adenocarcinoma, NOS in the left lower lobe lung is a separate primary.

The steps used to arrive at this decision are:

Open the Multiple Primary and Histology Coding Rules manual. For a lung primary, use the Lung Multiple Primary rules to determine the number of primaries.

The 2010 right lung bi-lobectomy showed two separate tumors that were determined to be two primaries: clear cell adenocarcinoma [8310/3] and adenocarcinoma, NOS [8140/3]. The histology of the new left lung mass is adenocarcinoma, NOS [8140/3].

Start at Rule M3 using the MULTIPLE TUMORS module because this patient has more than one tumor. The rules are intended to be reviewed in consecutive order within the module (i.e., from Rule M3 to Rule M12 in this case). Stop at the first rule that applies to the case you are processing. This patient has two tumors in each lung with ICD-O-3 histology codes that are different at the second (xxxx) digit. Abstract the LLL adenocarcinoma as a new primary [C343, 8140/3].

The patient has two tumors in each lung. The right lung showed adenocarcinoma and clear cell adenocarcinoma. The two tumors in the left lung were both adenocarcinomas. Clear cell adenocarcinoma [8310] on the right is different at the second digit from adenocarcinoma [8140] on the left. Rule M12 cannot be applied to this case, because Rule M7 is the first rule that applies to this case when processing the rules in consecutive order.

20110079 MP/H Rules/Histology: In the MP/H Manual, where is the documentation indicating "focal" is not a term that can be used to code histology? See Discussion. Example: neuroendocrine carcinoma with focal squamous differentiation. For the purposes of the MP/H rules, the term "focal" is not used to indicate a more specific histology. Terms that may be used to indicate a more specific histology are listed in the relevant histology rules. For example, see Breast histology rule H3. Notice the terms listed in the note for this rule are "type, subtype, predominantly, with features of, major, with ___ differentiation, architecture or pattern." The term "focal" is not included. This concept will be clarified in future revisions to MP/H rules. 2011

Multiple primaries--Heme & Lymphoid Neoplasms: Is a recently diagnosed granulocytic sarcoma followed by a diagnosis of AML two primaries? See Discussion.

6/10/10 Axillary lymph node biopsy was compatible with AML. The physician noted that the patient was diagnosed with granulocytic sarcoma [9930/3] in the axillary node.

6/15/10 Bone marrow biopsy compatible with AML FAB M1 [9873/3].

After induction, a second bone marrow biopsy on 6/30/10 shows persistent/refractory AML. The physician noted that the second biopsy is compatible with AML FAB M7 [9910/3].

Is the granulocytic sarcoma a chronic form of the disease? If so, do we have one primary diagnosed 6/10/10 with primary site coded to C42.1 and histology coded to 9873/3? Does the second biopsy on 6/30/10 represent the same primary even though the persistent disease is now FAB M7?

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

Granulocytic sarcoma does not transform into AML. Per the Abstractor Notes section in the Heme DB under the term "granulocytic sarcoma," it indicates that "Myeloid sarcoma (also known as granulocytic sarcoma) may occur de novo; it may precede or coincide with AML, or represent an acute blastic transformation of myelodysplastic syndromes." This means that when granulocytic/myeloid sarcoma is seen with AML, it represents a solid manifestation of the systemically involved AML. In other words, it is all the same disease process (coded to AML) if it occurs simultaneously (i.e., at the same time or within 21 days of on another).

Apply Rule M3 to this case which states to abstract a single primary when a sarcoma is diagnosed simultaneously or after a leukemia of the same lineage. Code the primary site to C421 [bone marrow] with histology coded to 9873/3 [acute myeloid leukemia, M1]. The FAB category is an older classification that is seldom used. Changes from FAB 1 to FAB 7 do not constitute a new primary.

20110082 First course treatment/Other therapy--Skin: How is PUVA [psoralen (P) and long-wave ultraviolet radiation (UVA)] coded when used for skin primaries such as melanoma and mycosis fungoides? Code PUVA as "Other treatment" with Code 1 - Other. We do not have a code specifically for ultraviolet radiation. 2011
20110048 First course treatment--Heme & Lymphoid Neoplasms: How is a "donor lymphocyte infusion" that is used in the treatment of CLL coded?

Donor lymphocyte infusion (DLI) is coded as immunotherapy. The lymphocytes are donated by the same person who donated the original stem cell transplant. The lymphocyte infusion creates an immune response in which the T-cells are activated to attack the cancer cells.

20110081 MP/H Rules/Histology--Pancreas: What is the correct histology code for pancreatic neoplasia III (PanIN III) for cases diagnosed in 2007 and later?

Code histology for PanIN-III to 8148/2 [Glandular intraepithelial neoplasia, grade III]. The Multiple Primary and Histology Coding Rules Manual is the correct source for coding histology.

For cases diagnosed 2007 or later, the following steps are used to determine the histology code:

Open the Multiple Primary and Histology Coding Rules manual. For a pancreas primary, use the Other Sites Histo rules to determine the histology code because pancreas does not have site specific rules.

Go to the SINGLE TUMOR: IN SITU ONLY module, start at rule H1. Code 8148/2 [Glandular intraepithelial neoplasia, grade III]. There is only one histologic type identified.

In the next version of the MP/H rules, the H22 rule "Code 8148/2 (Glandular intraepithelial neoplasia grade III) for in situ glandular in sites such as the (PAIN III)" will be included under H2 as well. Currently the rule is only in the MULTIPLE TUMORS ABSTRACTED AS A SINGLE PRIMARY module and should also be include under the SINGLE TUMOR: IN SITU only module.
