20130189 | Reportability--Brain and CNS: Are the terms 'mass' and 'lesion' reportable terms for accessioning brain and CNS primaries? See Discussion. |
With respect to reportability, the SEER Manual mentions 'tumor' and 'neoplasm,' but not 'mass' or 'lesion.' The SEER MP/H Manual states tumor, mass, lesion and neoplasm are equivalent terms for determining multiple primaries, but does this apply to reportability? If not, what is the distinction? |
'Mass' and 'lesion' are not reportable terms for benign/borderline brain and CNS tumors. Reportable terms for benign/borderline brain and CNS primaries are 'tumor' and 'neoplasm.' These terms appear in the ICD-O-3. 'Lesion' and 'mass' do not appear in the ICD-O-3. Do not use the MP/H Manual to determine reportability; page 2 of the SEER Manual is the correct source for reportability instructions. |

20130221 | MP/H Rules/Multiple primaries--Prostate: How many primaries are accessioned for a diagnosis of metastatic small cell neuroendocrine carcinoma of the prostate following a previous diagnosis of adenocarcinoma of the prostate? See Discussion. | Would a second prostate primary with histology coded to 8041/3 [small cell carcinoma] be accessioned for the following examples? Or are these metastases despite the different histologies?
Example 1: Prostate adenocarcinoma diagnosed in 2001, no treatment given. Metastatic small cell neuroendocrine carcinoma diagnosed 03/2012 on liver biopsy with a physician's statement in 4/2012 that the prostate is likely the cause of the metastasis to the liver.
Example 2: Prostate adenocarcinoma diagnosed in 2006, treated with TURP. Bone marrow biopsy in 5/2012 shows involvement by metastatic small cell carcinoma with morphologic and immunophenotypic features that argue against prostatic adenocarcinoma. The oncologist assessment states, "The patient has Stage 4 small cell carcinoma of the prostate and the bone marrow biopsy path shows metastatic small cell carcinoma (likely prostate in origin)." |
Accession two primaries, adenocarcinoma [8140/3] of the prostate [C619], followed by small cell (neuroendocrine) carcinoma [8041/3] of the prostate [C619] for each of the examples given per Rule M10.
In each case, the second histology (because it is not adenocarcinoma) is a new prostate primary. Small cell carcinoma and small cell neuroendocrine carcinoma are not adenocarcinomas. As a result they are not covered by Rule M3. |

20160039 | First course treatment/Surgery of Primary Site: If a procedure stated to be an "excisional biopsy" doesn't grossly remove the tumor, should Surgery of Primary Site be coded as an excisional biopsy? See Discussion for example. |
Would you code an excisional biopsy as Surgery for the following case?
The patient presented with a large protruding polypoid anal canal mass. The diagnosis of malignancy was made following a procedure referred to by the surgeon as an excisional biopsy. The protruding portion of the anal canal mass was excised, but the deep margin was grossly involved. The PE exam after the "excisional biopsy" found a firm mass, 4 cm in length on DRE. Further work-up with imaging showed gross residual disease extending to adjacent skeletal muscle (external anal sphincter). Although the internal/protruding anal canal portion of the tumor was excised, there was clearly extensive residual tumor. The patient underwent definitive concurrent chemoradiation only; subsequent surgery was not planned or performed. |
Do not record this excisional biopsy as surgery because there was residual macroscopic tumor. See Note 1 under #4 on page 130 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf |

20230040 | First Course Treatment/Hormone Therapy--Prostate: Is Lupron first course therapy in a patient who initially elected active surveillance for prostate cancer and then consented to treatment with Lupron? See Discussion. |
in March, the patient with stage cT1c, Gleason grade 7, prostate cancer elected active surveillance. In April, the patient consented to treatment with Lupron. There was no evidence of disease progression. According to the rules on page 161 of the 2023 SEER manual, we think the answer is yes, but the reporting hospital states that this is second course therapy. |
Code Lupron as second course therapy and code active surveillance as first course therapy in this scenario. The 2023 SEER Manual states to code all treatment data items to 0 or 00 (Not done) when the physician opts for active surveillance, deferred therapy, expectant management, or watchful waiting. Assign code 2 to Treatment Status. Active surveillance is not the same as "refusing treatment." Active surveillance is a valid option offered to the patient. The patient chose this option and later changed their mind. This is not a refusal of recommended treatment. Document all the details in the appropriate treatment text fields. |

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. |

20120095 | MP/H Rules/Multiple primaries--Breast: How many primaries are accessioned if a patient is diagnosed with inflammatory carcinoma of the left breast, (ductal with apocrine features type on biopsy), and an incidental lobular carcinoma in the right breast? See Discussion. | A 1.2 cm lobular carcinoma was incidentally discovered during the work-up of the patient's left breast that was inflammatory carcinoma. The lobular carcinoma on the right was localized without any skin involvement. Rule M6 indicates inflammatory breast carcinoma in either breast is a single primary. Does rule M6 apply when the patient has inflammatory carcinoma in one breast and a separate lobular carcinoma in the other? | For cases diagnosed 2007 or later, accession two primaries, ductal with apocrine features in the left breast and lobular carcinoma in the right breast.
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 Breast MP rules because site specific rules exist for this primary.
Start at the MULTIPLE TUMORS module, rule M4. The rules are intended to be reviewed in consecutive order within a module. The patient has tumors in both the right and left breasts.
Rule M6 does not apply because inflammatory carcinoma involves only the left breast and the patient has a different histology in the right breast and there is no mention of inflammatory carcinoma in that breast. In this situation continue to the next applicable rule. |

20031187 | Histology--Lymphoma: What code is used to represent the histology "monomorphic post-transplant lymphoproliferative disorder [diffuse large B-cell lymphoma]"? See Description. |
A 14 year old with a cadaver kidney transplant in 1994 for membranous glomerulonephritis presented in 6/26/03 with a right cervical LN with biopsy showing "lymph node involved by monomorphic post-transplant lymphoproliferative disorder (diffuse large B-cell lymphoma). Staging was done including a bone marrow which was negative, CSF negative. The oncologist on the case reduced the immunosuppression drugs with the final outcome being no sign of the lymphoma. | For cases diagnosed prior to 1/1/2010:Code 9680/36 [Diffuse large B-cell lymphoma]. This post-transplant lymphoproliferative disorder was diffuse large B-cell lymphoma. According to the World Health Organization, there are two types of post-transplant lymphoproliferative disorder. "Regular" post transplant lymphoproliferative disorder is not a neoplasm and is therefore not reportable to a cancer registry. The second type (sometimes called Hodgkin-like PTLD) is classified as a B-cell lymphoma, which means that it IS reportable.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ. |

20031015 | EOD-Extension--Lymphoma: How is the following guideline of "any mention of lymph nodes is considered indicative of involvement" applied for EOD-Extension of lymphoma cases when there is a discrepancy between physicians as to the stage at diagnosis? See discussion. | A biopsy of mesenteric nodes confirmed lymphoma. A bone marrow biopsy was negative. A CT of the chest indicates "small mediastinal and bilateral hilar nodes, but without convincing adenopathy." The case was Stage 2 per the oncologist and Stage 3 per the surgeon's TNM form. | For tumors diagnosed 1998-2003:
Based on the information provided for this example, the lymphoma involves one site, mesenteric nodes. Code EOD extension as 10 [Involvement of a single lymph node region]. The statement "For lymphomas, any mention of lymph nodes is indicative of involvement" refers to the terms in the paragraph above it on page 8 of the EOD manual: Palpable, enlarged, visible swelling, shotty, lymphadenopathy. While these terms are ignored for other malignancies, they should not be ignored for lymphomas. None of these terms apply to the example provided here. According to the CT, the mediastinal and hilar nodes are "small" "without convincing adenopathy." In other words, the mediastinal and hilar nodes are negative. |

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. |

20020063 | EOD-Extension--Breast: How do we interpret "dermal lymphovascular space invasion" and "dermal lymphovascular invasion" for extension? See discussion. | A breast path report states tumor invades dermal lymphovascular spaces. Also, pathologists sometimes state "dermal lymphovascular invasion". Are both these terms synonymous with dermal lymphatic invasion? | For cases diagnosed 1998-2003:
Dermal lymphovascular invasion and tumor in dermal lymphatics would both be coded as dermal lymphatic invasion. |
