MP/H Rules/Multiplicity Counter--Lung: If metastatic tumors are not counted in this field, should the multiplicity counter be coded to 01 for a case with a primary left lower lobe of lung tumor with a satellite tumor in the left upper lobe?
For cases diagnosed 2007-2013:
No, code multiplicity counter to 02 [two tumors present]. According to the multiple primary rules, these two lung tumors are reported as a single primary. Record the number of tumors reported as a single primary in Multiplicity Counter.
Multiplicity Counter no longer required by SEER as of 1/1/2013.
Histology--CLL/SLL: What is the correct histology code for a lymph node described in the pathology report comment section as "phenotypically consistent with chronic lymphocytic leukemia"? See Discussion.
Current rules instruct us to select the lymphoma code for lymph node and/or tissue with the dual diagnosis of chronic lymphocytic leukemia/small lymphocytic lymphoma. We have a cervical lymph node biopsy with that dual diagnosis, however, the pathology comment states that after immunohistochemistry testing, the lymph node is "phenotypically consistent with chronic lymphocytic leukemia." No bone marrow or blood work-up is performed.
For cases diagnosed prior to 1/1/2010:Code Small Lymphocytic Lymphoma. The current rules have not changed. Code to lymphoma because the diagnosis was made on a lymph node.
"Phenotypically consistent" means the lymph node contains CLL/SLL, not some other hematopoietic or metastatic disease.
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.
MP/H Rules/Multiple Primaries--Bladder: The new multiple primary rule M7 states that tumors diagnosed more than three years apart are multiple primaries. Does this apply to in situ bladder tumors that occur more than three years apart and to an in situ tumor that occurs three years after an invasive tumor?
For cases diagnosed 2007 or later, use the MP/H rules in order. Rule M6 comes before rule M7.
M6 states that bladder tumors with certain histologies are a single primary. It is a single primary regardless of timing if there is any combination of:
papillary carcinoma [8050]
transitional cell carcinoma [8120-8124]
papillary transitional cell carcinoma [8130-8131]
Rule M7 applies to bladder tumors with histologies other than those listed above. If you have such a case, rule M7 applies to in-situ tumors and to an in situ three years after an invasive.
Radiation Therapy--Prostate: Is the regional treatment modality XRT best coded to 50 (brachytherapy, NOS), 53 (LDR) or 54 (HDR) when the documentation indicates only "I-125 seeds" to the prostate?
Assign code 53 [Brachytherapy, interstitial, LDR] for seeds to the prostate. Seeds are always low dose because they are left in place and the radioactivity decays over time.
MP/H Rules/Multiple Primaries--Breast: How many primaries are to be abstracted when two tumors occur in one breast and both are ductal with the smaller tumor representing tubular carcinoma [variant]? See Discussion.
Right breast partial excision: Two invasive foci, one measuring 0.2cm and the second measuring 0.5cm. Both lesions are ductal carcinoma with the smaller representing tubular carcinoma (variant).
The breast histology table does not list tubular as a type of ductal, however, the pathologist states ductal carcinoma, tubular variant.
For cases diagnosed 2007 or later, this is two primaries of the right breast, using the 2007 MP/H rules. For the purposes of the 2007 rules, tubular is not a specific type of duct. Duct carcinoma (8500) and tubular carcinoma (8211) are different at the second digit of the histology code. Rule M12 applies, making these separate primaries.
MP/H Rules/Multiple Primaries--Melanoma: Is there a difference between multiple primary rules M6 and M7 because both rules state that tumors occurring more than 60 days apart are to be reported as multiple primaries? See Discussion.
Rule M6 clearly states that an invasive melanoma occurring more than 60 days after an in situ melanoma is a multiple primary. However M7 states that any melanomas diagnosed more than 60 days apart are multiple primaries. Since M7 does not state malignant melanomas diagnosed more than 60 days apart, this implies that any scenario:
in situ following an invasive,
invasive following an in situ,
in situ following an in situ,
or invasive following an invasive
are all multiple primaries if more than 60 days apart. If that is the intent of M7, then M6 is totally unnecessary. If the intent of M7 is only for an invasive following an invasive, then the word malignant needs to be inserted as the first word of rule M7.
For cases diagnosed 2007 or later, M7 is intended to apply to in situ and invasive melanomas. Therefore, M6 and M7 are repetitive.
This will be corrected when revisions are made to the MP/H rules. In the meantime, both M6 and M7 result in multiple primaries so it does not matter which rule is used.
MP/H Rules--Urinary: How many primaries are abstracted when a patient has a May 2000 invasive papillary transitional cell carcinoma of the bladder, a November 2004 invasive papillary transitional cell carcinoma of the right ureter and a May 2007 urothelial carcinoma in situ of both the left and right ureters?
For cases diagnosed 2007 or later:
Using the pre-2007 multiple primary rules, the PTCC of the bladder in 2000 and the invasive TCC of the right ureter in Nov. 2004 would have been abstracted as separate primaries.
Use the 2007 MP/H rules to evaluate the May 2007 diagnosis. Start with rule M3. Stop at rule M8. The May 2007 diagnosis is the same primary.
Rule M4 does not apply because of the 2000 bladder primary. A clarification will be added to M4 to stress that for the urinary rules, any urinary tumor up to the present point in time is counted when applying this rule.
Flag: For cases diagnosed prior to 2001, how is the ICD-O-3 Conversion Flag set if the ICD-O-2 and ICD-O-3 histology and behavior fields are both directly coded, as registrars in this region are instructed to do when submitting late cases, and as a result no conversion is necessary? Is it to 0 [Morphology (Morph--Type&Behav ICD-O-3 originally coded in ICD-O-3)] or Blank [Not converted]?
Assign code 3 [converted with review].
In your scenario above, ICD-O-2 and ICD-O-3 are being independently coded which should yield the same result as converting the case and then reviewing it.
Otherwise, if there is an ICD-O-3 code which differs from the ICD-O-3 code based on the conversion criteria, it will trigger an edit.
Multiple Primaries--Brain and CNS: How many primaries should be recorded in a patient with von Hippel Lindau disease that has a hemangioblastoma of the cerebellum in 2003 and a hemangioblastoma of the brainstem in 2007?
A tumor of the cerebellum (C716) and a tumor of the brainstem (C717) are multiple primaries because the topography codes are different at the fourth character of site.
Reportability/Ambiguous Terminology--Esophagus: Is a case with a biopsy diagnosis of "... focal areas suspicious for adenocarcinoma in situ change" reportable if the diagnosis on the partial esophagectomy specimen only includes the phrase "... with foci of high grade dysplasia; no invasive carcinoma identified"?
The case is not reportable.
The biopsy with a suspicious result (suspicious for adenocarcinoma) was disproven by the esophagectomy.
