20110099 | Primary site--Heme & Lymphoid Neoplasms: How is primary site coded for bilateral pelvic lymph node involvement for lymphoma primaries? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. The PH rules for coding lymphomas (Module 7) refer to a lymph node region as defined by the ICD-O-3. Per the Appendix C, , the ICD-O-3 lymph node region for "pelvic" is C775. In this case, there is one lymph node region involved (bilaterally). Per Rule PH20, code the specific lymph node region when multiple lymph nodes within the same lymph node region (as defined by the ICD-O-3) are involved, C775. Per Note 1 under Rule PH20, use this rule when there is bilateral involvement of lymph nodes. This same table in Appendix C also provides information on how left and right pelvic lymph nodes are categorized by AJCC for purposes of coding stage. If the left and right pelvic lymph nodes are positive for lymphoma, it is involvement of two regions. The case is coded as Stage II. Keep in mind that the ICD-O-3 definition of regions is used to code the primary site, while the AJCC definition of regions is used to code stage.

20110044 | MP/H Rules/Histology--Corpus uteri: What are the histologies for the primaries to be reported when the endometrium contains two separate tumors composed of adenocarcinoma with multiple differentiations as well as a separate small focus of clear cell carcinoma? See Discussion. |
The resected specimen showed, "Adenocarcinoma of endometrium with the following features: Histologic type: Endometrioid with squamous and focal clear cell differentiation. A second focus of endometrial adenocarcinoma is present in the fundus with admixed complex atypical hyperplasia in a polypoid, non-invasive mass. The second tumor is endometrioid with secretory differentiation. COMMENT: The tissue in between the two tumors is sampled, and contains foci of endometrial adenocarcinoma that is superficially present within the endometrium, as well as a small focus of clear cell carcinoma measuring 0.2 cm." Per MP/H rules M17, this is counted as multiple primaries because the histology codes differ at the third digit: 8323/3, 8382/3, 8310/3. The Multiple Primary rules make no reference to the histology tables. There is also no rule to ignore the in situ tumor. In addition, the histology table in the 2007 MP/H Rules Manual for Other Sites does not include "secretory differentiation" as a type of GYN malignancy. |
After consultation with our expert pathologist, the decision is report this case as a single primary. There was some confusion about how to apply the current MP/H rules to this pathology report given 1) the definition of M16 and M17 and 2) the likelihood for a single endometrial primary to present with several differentiations. According to our expert pathologist, "I would regard this case as a single endometrial primary with extensive endometrial involvement and several types of differentiation, all of which are seen in endometrial carcinomas." Next, 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 an endometrial primary, use the Other Sites Histo rules to determine the histology code because endometrium does not have site specific rules. Start with the MULTIPLE TUMORS ABSTRACTED AS A SINGLE PRIMARY module, Rule H18. The rules are intended to be reviewed in consecutive order within the module from Rule H18 to Rule H31. You stop at the first rule that applies to the case you are processing. Code the appropriate combination/mixed code (Table 2) when there are multiple specific histologies. GYN malignancies with multiple types of adenocarcinoma have histology coded to 8323/3 [mixed cell adenocarcinoma] per rule H30. |

20110066 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be accessioned for a patient with a history of CLL undergoing chemotherapy who is subsequently diagnosed on a liver biopsy with diffuse large B-cell lymphoma (Richter transformation)? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Abstract the diffuse large B-cell lymphoma (Richter transformation) as a second primary per Rule M10. Rule M10 states to abstract as multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm (CLL) AND there is a second diagnosis of an acute neoplasm (the diffuse large B-cell lymphoma (Richter transformation)) more than 21 days after the chronic diagnosis.
"Richter transformation," also known as "Richter syndrome," is a term that indicates CLL has transformed to DLBCL. Richter syndrome is listed under the Alternate Names section in the Heme DB for DLBCL (9680/3).

20110090 | MP/H Rules/Histology/Behavior--Ovary: How are these fields coded for a 20 cm borderline mucinous tumor with a 0.3 cm minor focus of intraepithelial carcinoma of the ovary that the pathologist stages as T1a? | According to the MP/H rules, code histology to 8010/2 [intraepithelial carcinoma] for cases diagnosed 2007-2014. Borderline mucinous tumor is not reportable to SEER.
The steps used to arrive at this decision are:
Go to the Other Sites Histo rules found in the Multiple Primary and Histology Coding Rules Manual.
Start at the SINGLE TUMOR: IN SITU ONLY module, rule H1. Code the histology when only one histologic type is identified. The only reportable histology in this case is intraepithelial carcinoma [8010/2]. |

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.

20110143 | Multiple primaries--Heme & Lymphoid Neoplasms: How many and what primary site(s) are to be accessioned when biopsies of clavicular and neck skin lesions are both consistent with mycosis fungoides? See Discussion. |
Per the Heme DB and Manual, this is a single primary; however, per the MP/H Rules, this would be multiple primaries. Which rules apply to this case? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. When there is a question of whether the SEER MP/H Rules or Hematopoietic and Lymphoid Neoplasm Rules apply, check the histology and refer to the Case Reportability Instructions in the Hematopoietic and Lymphoid Neoplasm Manual. All ICD-O-3 morphology codes in the range 9590 - 9992 are included in the Hematopoietic Rules. Mycosis Fungoides [9700/3] is included in this range. Therefore, the SEER MP/H Rules do not apply to mycosis fungoides. This case should be accessioned as a single primary: mycosis fungoides [9700/3] of the skin, NOS [C449]. Per Rule M2 abstract a single primary when there is a single histology. Note that in the Primary Site(s) section of the Heme DB, it states the primary site must always be coded to skin (C440 - C449) for mycosis fungoides. Because the primary site is stated in this section of the Heme DB, it is not necessary to use the Primary Site Rules to determine the primary site. Code the primary site to C449 [skin, NOS] because the patient has multiple sites of skin involvement and there is no documentation indicating which subsite of skin was the origin of the mycosis fungoides.

20110150 | Ambiguous Terminology--Heme & Lymphoid Neoplasms: As ambiguous terminology is not used to code histology for Heme & Lymphoid primaries, how is the histology coded when a patient has a clinical diagnosis of "consistent with a myelodysplastic syndrome"? See Discussion. | The physician states the "patient's clinical picture certainly is most consistent with MDS." Several FISH probes were performed on peripheral blood, specifically looking for the 5q minus syndrome as well as other molecular rearrangements to suggest or confirm MDS. These studies came back as normal. The initial bone marrow also came back negative. The physician then states, "The suspicion was that this represented a myelodysplastic syndrome despite the normal cytogenetics. Additional studies performed on the date of the clinic visit included the FISH for the 5q minus syndrome as well as CD59 to exclude PNH. Both of these were negative. Therefore, at this juncture, the patient has a macrocytic anemia not yet requiring transfusion support with a normal white count and an elevated platelet count and a hypercellular bone marrow. This is certainly consistent with a myelodysplastic syndrome."
Per coding guidelines, ambiguous terminology is not used to code histology, only for reportability. What is the histology code for this case? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology as Myelodysplastic syndrome, unclassifiable [9989/3].
Ambiguous terminology is used to accession cases (determine reportability). While ambiguous terminology is generally not used to code a specific histology, it can be used to code histology if it is the .
The statement that you do not use ambiguous terms to code histology is intended for those NOS histologies with an ambiguous term being used to describe the subtype. For example, if the physician states this is a myelodysplastic syndrome, NOS, refractory thrombocytopenia. The correct histology would be MDS, NOS [9989/3] and not refractory thrombocytopenia [9992/3].

20110008 | MP/H Rules/Histology--Vulva: How is histology coded for VIN III with focal invasion? See Discussion. | Per SINQ 20000442, the histology for CIN III with microinvasion is coded to 8077 [squamous intraepithelial neoplasia, grade III] per the matrix system rules, with a behavior code of /3 [malignant]. Coding the histology to 8077/3 per the matrix principle causes IF25_3 and MorphICDO3_P1 edits to fail. Flagging the first error resolves any reporting issue. How is the MorphICDO3_P1 edit resolved? | Assign 8076/3 [squamous cell carcinoma, microinvasive] for VIN III with focal invasion. This applies to all terminologies listed under 8077/2. The SINQ question from 2000 will be retired. | 2011 |
|
20110121 | MP/H Rules/Histology--Esophagus: Will the AJCC TNM 7 having separate stage groupings for squamous cell carcinoma and adenocarcinoma result in coding histology for a tumor of mixed squamous cell carcinoma and adenocarcinoma to squamous cell carcinoma because it has the poorer prognosis? See Discussion. | Per the CS Esophageal Schema, Note 4, there are now separate stage groupings for squamous cell carcinoma and adenocarcinoma. Should a tumor of mixed histopathologic type be classified as a squamous cell carcinoma?
|
Do NOT use the Collaborative Stage Manual to determine the histology code. For CS STAGING purposes only, coding should be based on the squamous cell carcinoma component of this tumor.
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 an esophagus primary, use the Other Sites Histo rules to determine the histology code because esophagus does not have site specific rules.
Start at Rule H8 because this is an invasive histology (assuming this is a single tumor). which states that one should code the appropriate combination/mixed code from Table 2 when there are multiple specific histologies.
Find Other Sites for Table 2 under the Terms & Definitions section of manual.
Locate the appropriate mixed code for squamous cell carcinoma and adenocarcinoma in column 1. Per column 3, the correct histology is adenosquamous carcinoma. Per column 4, the correct histology is 8560/3. |

20110065 | Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when a skin (right thigh) biopsy is consistent with mycosis fungoides (cutaneous T-cell lymphoma)? See Discussion. | Applying rule M15 (multiple primaries calculator) indicates this is two primaries. Is this correct? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the primary site to C447 [skin of lower limb] and code histology to 9700/3 [mycosis fungoides]. he pathologist wrote in parentheses that this was cutaneous (i.e. primary site is skin) and that it is a T-cell lymphoma (mycosis fungoides is a T-cell lineage). So the parenthetical statement was not a separate diagnosis; rather a general classification of the mycosis fungoides. "CTCL" is listed under the Alternate Names section of the Heme DB. CTCL is an abbreviation for cutaneous T-cell lymphoma. CTCL is a synonym for mycosis fungoides. This is a single primary per M2 which states to abstract a single primary when there is a single histology.
