20091103 | Reportability/Ambiguous Terminology--Prostate: Is a prostate biopsy that states "highly suspicious for, but not diagnostic of adenocarcinoma, suggest another biopsy" reportable? | Do not report. "Not diagnostic of" means that while the pathologist is seeing some features that resemble cancer, there are not enough features to feel comfortable making an unquestionable diagnosis. Watch for another biopsy of the patient in the next 3-6 months. The statement "not diagnostic of" overrules the "highly suspicious" statement. | 2009 | |

20091078 | MP/H Rules/Multiple Primaries--Head & Neck: How many primaries should be reported when an invasive squamous cell carcinoma of the right mandibular body (C06.9) was diagnosed in 2004 (treated with surgery and radical neck dissection), and an invasive squamous cell carcinoma of the left buccal mucosa (C06.0) was diagnosed in 2007? See Discussion. | According to the MP/H Rules, it appears Rule M12 would apply since none of the others fit and these would be a single primary. | For cases diagnosed 2007-2014: Based on the information provided, the primary site code for the 2004 primary should be C031 [mandibular gingiva, lower alveolar mucosa, etc.]. The 2007 diagnosis would be a separate primary according to rule M7 because the patient was disease free following treatment for the 2004 diagnosis. C031 and C060 are different at the third character. |

20091090 | First course treatment--Leukemia: How should an allogeneic stem cell transplant for acute myeloid leukemia be coded in the Hematologic Transplant and Endocrine Procedures field? See Discussion. | There is debate as to whether this procedure should be coded as a 12 in order to capture the allogeneic part of the procedure. | Assign code 20 [Stem cell harvest (stem cell transplant) and infusion as first course therapy] for stem cell procedures, even allogeneic procedures. | 2009 |
|
20091058 | MP/H Rules/Histology--Kidney: How is histology coded when it is described in the pathology report as "Histologic type: Clear cell (conventional) renal cell carcinoma. Percent of sarcomatoid component: 10%"? See Discussion. | MP/H rules for kidney, Table 1 lists both clear cell and sarcomatoid as specific types of renal cell carcinoma. The MP/H terms and definitions for kidney state that clear cell is architecturally diverse. For this case, does the sarcomatoid component represent a subtype of clear cell that has not been assigned an ICD-O code, and thus histology should be coded to 8310? Or does the sarcomatoid component represent a specific type of renal cell carcinoma for which rule H6 would apply? Should histology be coded 8255 for this case? | For cases diagnosed 2007 or later, assign code 8310 [clear cell adenocarcinoma] according to rule H5. Renal cell, clear cell and sarcomatoid are mentioned in the diagnosis. Sarcomatoid is referred to as a component. Component is not one of the terms listed in rule H5 that indicate a more specific type. Ignore sarcomatoid in this case. Use table 1 to identify clear cell as a specific renal cell type. Code the specific type (clear cell) according to rule H5. | 2009 |
|
20091110 | MP/H Rules--Bladder: Should an invasive urothelial carcinoma of the bladder diagnosed in 2004 followed by an in situ urothelial carcinoma of the ureter diagnosed in 2008 be reported as multiple primaries per the three-year guideline in Rule M7 or a single primary per the subsite guideline in Rule M8? See Discussion. | Rule M7 states, "Tumors diagnosed more than three (3) years apart are multiple primaries." Should this rule be modified to say, "Bladder tumors diagnosed more than three (3) years apart are multiple primaries"? Does Rule M7 apply to only bladder tumors or does this rule apply to tumors in any of the urinary sites similarly to Rule M8 which states, "Urothelial tumors in two or more of the following sites are a single primary: Renal pelvis (C659) Ureter (C669) Bladder (C670-C679) Urethra/prostatic urethra (C680)"? | For cases diagnosed 2007 or later, Rule M7 pertains to renal pelvis, ureter, bladder and other urinary sites as defined by the topography codes listed in the header of these rules.
An invasive urothelial bladder tumor followed more than three years later by an in situ TCC of the ureter are reported separate primaries. Rule M8 applies when the tumors in these sites are diagnosed within three years of each other.

20091055 | Date therapy initiated/Systemic/Surgery Sequence--Breast: How are these fields coded when a patient has chemotherapy after a sentinel lymph node biopsy and has a lumpectomy after completing chemotherapy? See Discussion. | On 4-10-08 a patient underwent sentinel lymph node biopsies. This was followed by chemotherapy which started on 4-15-08. The patient subsequently underwent a lumpectomy on 11-10-2008. | For this case, code Date Therapy Initiated to the date of the sentinel lymph node biopsy [04102008]. Assign code 3 [Systemic therapy after surgery] in Systemic/Surgery Sequence. |

20091119 | MP/H Rules/Multiple primaries--Lung: How many primaries are to be reported for an adenocarcinoma of the lung in the right middle lobe of the lung and bronchioalveolar carcinoma, non-mucinous type in the right upper lobe? See Discussion. |
Bilobectomy revealed two tumors, adenocarcinoma in the right middle lobe and bronchioalveoar carcinoma non-mucinous type in the right upper lobe. MP/H rule M10 states that tumors with non-small cell carcinoma (8046) and a more specific non-small cell type (chart 1) are a single primary. Does rule M10 apply to only those cases for which one tumor is stated to be non-small cell, NOS? Or do we use chart 1 to identify specific subtypes? For this case, using chart 1, would we note that bronchioalveolar is a subtype of adenocarcinoma and count this case as a single primary? Most of the MP/H rules schemas have a rule making an adenocarcinoma and a more specific type of adenocarcinoma a single primary. Would we apply rule M10 to this case and count it as a single primary? Or would we move on to rule M11 and count the case as two primaries? |
For cases diagnosed 2007 or later, Rule M11 applies. Accession two primaries. Rule M10 applies only to cases for which one tumor is stated to be "non-small cell carcinoma." |

20091085 | MP/H Rules/Histology--Breast: How is histology coded for a breast primary with a final diagnosis of "infiltrating duct carcinoma with apocrine features"? See Discussion. | I & R has conflicting answers: #25719 (dated 3/17/2008) says per rule H12 this is 8401/3 but #23347 (dated 8/12/07) says per rule H16, this is 8523/3. | For cases diagnosed 2007 or later, assign histology code 8401/3 [apocrine adenocarcinoma] according to rule H12. Apocrine is a type of duct carcinoma, see table 1. Code 8401 should be listed in Rule H12. Apocrine should be removed from table 3. These corrections will appear in the revised version of the rules. |

20091031 | MP/H Rules/Histology--Thyroid: How is histology coded for a thyroid tumor described as "predominantly papillary carcinoma, tall cell variant, follicular type"? | For cases diagnosed 2007 or later, assign code 8340 [Papillary carcinoma, follicular variant] according to rule H15 for Other Sites. "Predominantly" and "type" indicate specific histologies. "Variant" does not. See rule H13. The histology in this case is papillary and follicular. Tall cell variant is ignored. |

20091042 | Multiple primaries--Hematopoietic, NOS: How many primaries should be coded when a patient has multiple occurrences of plasmacytoma followed by a diagnosis of multiple myeloma? See Discussion. | Example: Patient had a diagnosis on February 2003, plasmacytoma of the sinus; June 2003, plasmacytoma of the alveolar ridge; July 2003, plasmacytoma of the skin; and June 2004, multiple myeloma.
If this represents a transformation of plasmacytomas to multiple myeloma, will the information on multiple myeloma be available for statistical and research purposes? |
For cases diagnosed prior to 1/1/2010:Accession this case as plasmacytoma diagnosed in Feb. 2003. Each of the subsequent diagnoses are not abstracted as new primaries. They are the "same," one primary only, according to the Definition of Single and Subsequent Primaries for Hematologic Malignancies (the tri-fold heme table). The 2003 diagnosis is a classic example of extraosseous plasmacytoma (9734/3). Plasmacytoma and multiple myeloma would be two primaries in the new hematopoietic rules taking effect in 2010. For cases diagnosed 1/1/10 and later, 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. |
