20071028 | MP/H Rules--Lung: Why the term "nodule" is not included as an equivalent term along with tumor, mass, lesion and neoplasm in the 2007 lung multiple primary rules? | Answer revised July 2008 For cases diagnosed 2007 or later: For the purpose of applying the Lung MP/H rules, the word "Nodule" can be used interchageably with "Tumor," "Mass," "Lesion" and "Neoplasm." HOWEVER, this does NOT apply to casefinding or staging. This revision will be added to the next version of the MP/H rules. Sinq question 20071028 will be revised. |

20071088 | Type of Multiple Tumors--Lung: Is this field coded to 40 [Multiple invasive] or 80 [Unk in situ or invasive] when only one nodule is biopsied of multiple existing nodules for a reported single lung primary? See Discussion. | The right lung has 4 tumor nodules in the upper lobe. Biopsy of one tumor is positive for moderately differentiated adenocarcinoma. No other work up performed. Should code 40 be used because we dont know the behavior of the other nodules? |
The best code to use in this case is 40 [multiple invasive]. For lung only, it is assumed that all of the tumors are the same histology and that all are invasive. | 2007 |
|
20071045 | Ambiguous Terminology: How is this field to be coded when there is a "conclusive term" exactly 60 days following the initial diagnosis? See Discussion. | Is code 1 [Ambiguous terminology diagnosis only within 60 days of initial diagnosis] or code 2 [Ambiguous term followed by a conclusive term more than 60 days after the initial diagnosis] to be used for a case that had a conclusive diagnosis at 60 days from initial diagnosis? The instructions on page 97 do not match the code definitions on page 95. | The definition for code 2 should be "More than 60 days" after the date of diagnosis. Code 1 is 60 days or less, code 2 is more than 60 days. This will be clarified in the first revision to the MP/H manual. |

20071077 | MP/H Rules/Multiple Primaries/Histology--Colon: How many primaries should be reported and how is the histology field(s) coded if the left colon contains two adenocarcinomas and one mucinous adenocarcinoma arising in a villous adenoma and each has a different level of invasion? See Discussion. | A patient had three tumors in the left colon including an 1) invasive well differentiated mucinous adenocarcinoma arising in tubulovillous adenoma with pericolonic subserosal fat invasion 8.5cm, 2) An infiltrative moderately differentiated colonic adenocarcinoma with invasion of muscularis propria 4cm and 3) an invasive moderately differentiated adenocarcinoma with invasion of muscularis propria, 1/69 nodes positive. The case was coded using rule M8 for one primary, but M10 contradicts; and H13 coding rule for histology 8263/3. | For cases diagnosed 2007 or later: Assuming that all tumors are in the left colon, there are three tumors:
Multiple Primary Determination In the colon MP rules go to the multiple tumors module. Start with M3. Stop at M7 and abstract as a single primary.
Histology Code Go to the histology coding rules, multiple tumors module, and start with H15. Stop at H20 which tells you to code the most invasive tumor. Tumor 1 is the most invasive according to the definition of most invasive in the 2007 SEER Manual, page C-271. Code 8263/3 [Adenocarcinoma in tubulovillous adenoma]. |

20071012 | Reportability--Melanoma: Is a skin excision final diagnosis of "melanocytic tumor with uncertain malignant potential" reportable if the path COMMENT states the initial shave biopsy diagnosis was "melanocytic tumor with uncertain malignant potential [minimal deviation melanoma]"? See Discussion. | SKIN, RIGHT FOOT, EXCISION: CHRONIC SCARIFICATION WITH RESIDUAL ATYPICAL MELANOCYTES IN THE DERMIS IDENTIFIED, BUT COMPLETELY EXCISED.
Comment: The prior outside biopsy report indicates that the lesion was a melanocytic tumor of uncertain malignant potential (minimal deviation melanoma) measuring at least 2.5 mm in depth. There was apparently no in situ component. Special stains performed here are similar, with positive reactivity for Melan A and S-100. The cells are atypical, but there are reactive changes, making it impossible to accurately assess the true nature of the lesion in this biopsy. If this is a minimal deviation melanoma, it would be classified as a T3 (T3a since there is no description in the outside report of ulceration) lesion. The atypical melanocytes extend to a depth of 1.1 mm in this 2 mm deep biopsy, but are completely excised, both at the deep margin and at all of the peripheral margins (closest margin is superior, with clearance of 7 mm).
PATH FROM INITIAL BIOPSY: Diagnosis: Rt dorsal foot, shave biopsy: Melanocytic tumor of uncertain malignant potential (see comment). Tumor depth at least 2.5mm Deep margin involved. Comment: As a primary lesion, I would favor that this represents a melanocytic tumor with indeterminate biologic potential also known as minimal deviation melanoma. The lesion does extend to the deep margin and wider excision is recommended. |
This case is not reportable. Based on the information provided, there is no definitive diagnosis of malignancy. | 2007 |

20071068 | MP/H Rules/Multiple Primaries/Histology--Prostate: How many primaries should be abstracted and how should the histology field(s) be coded for a case in which the pathology specimen showed adenocarcinoma in 20% of the tissue and sarcoma in 50% of the tissue? See Discussion. | Patient has TURP. The final path diagnosis is adenocarcinoma in 20% of tissue and sarcoma in 50% of tissue. Because it is unknown whether there is a single or multiple tumors, rule M1 (Other Sites) is used which states the case is to be abstracted as a single primary. Single invasive histology rules are followed to rule H16, but table 2 does not contain a mixed code for this situation, even though ICD-O-3 has a code 8933/3 for "adenosarcoma". Therefore, rule H17 is applied that states to use the highest code, which in this case would be 8800/3 [Sarcoma, NOS]. Is this correct? |
For cases diagnosed 2007-2014, code as two primaries, one adenocarcinoma and the other sarcoma. This is two tumors (adenocarcinoma and separate sarcoma) until proven otherwise. Do not code as adenosarcoma, as this is a gyn-specific diagnosis. Adenosarcoma of the prostate is not a recognized entity in the WHO classification of prostate tumors. |

20071119 | CS Eval/Surgery of Primary Site--Colon: When the only procedure performed is a polypectomy, if there is NO tumor at the margins, should CS TS/EXT-Eval be coded as 3 and the surgery coded as a polypectomy? | This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Assign eval code 3. A polypectomy with no tumor at the margin meets the criteria for pathologic staging. Code polypectomy in Surgery of Primary site in this case. |

20071069 | First Course Treatment--Melanoma: How and where is the excision for an in-transit metastasis coded if the in-transit metastasis is coded in CS Lymph Nodes? See Discussion. | Excision of skin of scalp nodule reveals in transit metastasis of melanoma. Patient also has lung metastasis and begins systemic treatment. No primary tumor identified. | Code the excision in Surgical Procedure of Other Site because no primary tumor was identified. | 2007 |
|
20071073 | MP/H Rules/Histology--Breast: How is histology coded for a single tumor with ductal and tubular features in only the invasive component and not in the in situ component? See Discussion. | A breast tumor diagnosed in Feb. 2007 is a single tumor with in situ and invasive components. The invasive component is diagnosed as ductal with tubular features. The only rule that applies is H9 which says 'code the invasive histology.' Is it ductal (8500) or tubular (8211)? If you continue through the H rules, then H12 does not apply, because tubular is not a type of ductal. So then you end up at H17, which would make this 8523. Which code is correct? |
For cases diagnosed 2007 or later, code the histology 8523 [duct mixed with other types of carcinoma]. After determining that the invasive histology is to be coded using rule H9, there is another decision to make in this case -- which invasive histology should be coded? Make a second pass through the histology rules, begining with rule H10. Stop at H17 and code 8523. This advanced concept of a "second pass" through the rules is discussed in an online web training session called "Beyond the basics."

20071114 | Ambiguous Terminology/Date of Diagnosis: How would you code the diagnosis date when the body of an imaging report uses reportable ambiguous terminology while the final impression in that same report uses non-reportable ambiguous terminology? Would you code the diagnosis date to the date of the scan or to the subsequent biopsy date that confirmed a malignancy? See Discussion. | Within the body of a mammogram report, the radiologist stated, "diffuse inflammatory tissue throughout the rt breast w/ large rt axillary lymph nodes, consistent with an inflammatory carcinoma of rt breast." His final impression, however, said "extremely suspicious rt breast w/ extremely dense breast parenchyma and adenopathy in axilla, suggesting an inflammatory carcinoma." The patient then went on to have a biopsy, which was indeed positive for cancer. | Accept the reportable ambiguous terminology from the body of the mammogram. Record the date of the mammogram as the date of diagnosis. The guidelines on page 4 of the 2007 SEER manual addressing discrepancies within the medical record can be applied to discrepancies within one report. The instructions are: If one section of the medical record(s) uses a reportable term such as apparently and another section of the medical record(s) uses a term that is not on the reportable list, accept the reportable term and accession the case. |
