Report Question ID Question Discussion Answer Year
20071083 MP/H Rules/Multiple Primaries--Bladder/Renal Pelvis: Is a non-invasive papillary transitional cell carcinoma of the bladder diagnosed one year after the occurrence of an invasive papillary transitional cell carcinoma of the renal pelvis reported as one or two primaries?

For cases diagnosed 2007 or later:

This is a single primary with renal pelvis as primary site.

Use the 2007 MP/H rules to determine if the 2007 diagnosis is a new primary. Use the Urinary rules, multiple tumors module. Start with rule M3. Follow the rules down to Rule M8 and stop. This is an example of implantation effect.

MP/H Rules/Recurrence: Is a subsequent diagnosis of an in situ tumor (bladder cancers excluded) a "recurrence" if it follows a prior invasive diagnosis of the original primary cancer made 5 years before?

For cases diagnosed 2007 or later, use the 2007 MP/H rules to determine whether or not a subsequent diagnosis (either invasive or in situ) is a new primary or a recurrence. Do not use the statement "recurrence" from the medical record to make this decision.

When evaluating a subsequent diagnosis and the MP/H rules indicate "single primary," the tumor being evaluated is a "recurrence" of the original primary cancer.

20071081 CS Site Specific Factor--Lymphoma: Can the registrar calculate the International Prognostic Index (IPI) score from information found in the H&P or on the back of a TNM form for the SSF 3 field if the physician does not document it in the medical record?

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.Record the IPI score in SSF3 when the score is documented in the medical record. If the score is not stated, do not calculate it.

20071080 First Course Treatment--Liver: Given that agents can be used that are not chemotherapy drugs, how should treatment be coded for a procedure called a "chemoembolization" when the agent used is not documented? This issue was discussed among the national standard setters and per the SEER website this issue has been resolved as follows: When "chemoembolization" is done but the agents used are not chemotherapy drugs, then treatment should be coded as "Other Therapy." See http://seer.cancer.gov/tools/codingmanuals/embolization.html 2007
20071079 MP/H Rules/Recurrence--Breast: Do we use a pathologists comment of "recurrent ductal carcinoma" found in the pathology report for a new specimen to determine whether the new specimen actually represents a new primary or recurrent disease? See Discussion.

The patient had a left breast cancer LIQ, ductal with DCIS. Nodes (-) diagnosed in 1998

Treatment: Lumpectomy-clear margins

Refused radiation

Hormone therapy: Tamoxifen

Present: June 2007

Left breast-invasive ductal ca, UOQ

Pathology report comments: Recurrent ductal ca.

Left axillary nodes (+)

For cases diagnosed 2007 or later, apply the 2007 MP/H breast rules. Go to the multiple tumors module and begin with rule M4. Stop at rule M5: tumors diagnosed more than 5 years apart are multiple primaries.

The only time you can accept a pathologist's statement of recurrence is when the statement is made based on a review of the slides from the previous diagnosis compared to the slides from the current diagnosis.

20071078 Scope of Regional Lymph Node Surgery/CS Reg LN Pos/Exam: How are these fields coded if the operative report does not mention a separate lymph node procedure at the time of the surgery to the primary site? See Discussion.

LUL lobectomy: 1.7 cm apical tumor, diagnosis: moderately well differentiated subpleural squamous cell carcinoma, with involvement of pleural surface. 3 peribronchial LN neg and 2 AP window LNs neg. Stage T2N0.

1. No lymph node dissection or sampling was stated to be done

2. The lobectomy specimen contained the LNs

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.

Code the Scope of Regional LN Surgery, Regional Nodes Positive and Regional Nodes Examined fields using the available information on the case. The lymph nodes can be obtained or biopsied during any procedure within the first course of treatment. A separate lymph node surgery is not required to complete these data items.

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:

  • Mucinous adenocarcinoma arising in a villous adenoma

  • Colonic adenocarcinoma

  • Colonic adenocarcinoma

    • 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].

    		20071076 MP/H Rules/Histology--Thyroid: Regarding rule H15, is the mixed code 8340 [Papillary carcinoma, follicular variant] used when there are subtypes of these histologies described, such as a tumor diagnosed with follicular and papillary microcarcinoma or should 8341 [Papillary microcarcinoma] be used?

    For cases diagnosed 2007 or later:

    For coding purposes, this is a papillary and follicular combination that would be coded to the combination code 8340/3 [Papillary carcinoma, follicular variant].

    For thyroid cancer only, the term micropapillary does not refer to a specific histologic type. It means that the papillary portion of the tumor is minimal or occult, usually less than 1 cm. in diameter.

    		20071075 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.

    		20071074 MP/H Rules/Multiple Primaries--Lung: How many primaries should be reported when an "adenocarcinoma" is discovered in one of several new nodules at the scar in a lung and it is less than a year after a wedge resection for a diagnosis of "bronchioalveolar adenocarcinoma" in the same lung? See Discussion.

    In March 2006 patient diagnosed with bronchioalveolar adenocarcinoma [8250/3] and had wedge resection. In November 2006 a CT chest shows nodules at the scar suspicious for recurrence. In January, 2007, there was a biopsy of one of the nodules showing adenocarcinoma [8140/3].

    Is this part of the original disease process diagnosed in March 2006 or should it be abstracted as a new primary based on 2007 MP/H rules (histology is different at the first 3 digits)?

    For cases diagnosed 2007 or later:

    Try to obtain more information/clarification on the 2007 diagnosis -- for example, is it metastasis?

    Based only on the information provided for this case, the 2007 diagnosis is a separate primary.

    Use the 2007 MP/H rules to assess the 2007 diagnosis. Begin with rule M3 in the multiple tumors section. Stop at rule M11, multiple primaries.
