Multiple Primaries (Pre-2007)--Bladder: Is a 1998 transitional cell carcinoma of the bladder, followed by a 2001 squamous cell carcinoma of the bladder reportable as a second primary?
For tumors diagnosed prior to 2007:
Yes. This case is reportable as a second primary. The rule in the SEER Program Code Manual says that invasive bladder cancers with histology codes 8120-8130 [papillary, transitional] are always coded as a recurrence and are an exception to the multiple primary rule. Squamous cell carcinoma [8070] is not a part of that exception.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Scope of Regional Lymph Node Surgery/EOD-Lymph Node fields: How do you code these fields if a pt has multiple lymph nodes surgeries at different times? See discussion.
Example: 1/01/03 Biopsy of 1 sentinel lymph node: positive for metastasis. 1/10/03 Modified radical mastectomy and axillary lymph node dissection: ductal carcinoma with 8 neg lymph nodes.
For cases diagnosed 1/1/2003 and later: Code Scope of Reg LN Surgery to 7. Code EOD Lymph Nodes field to 6. Code EOD Pathologic Number of Reg LN Positive and Examined fields to 01 and 09 respectively.
For the Scope of Reg LN Surgery use the highest applicable code number if more than one Scope of Reg LN Surgery was performed. The EOD lymph node fields are cumulative and count all lymph nodes removed during the diagnostic and first course treatment procedures.
Histology (Pre-2007)/EOD-Lymph Nodes/SEER Summary Stage 2000--Breast: What codes are used to represent these fields for a breast case with a diagnosis of ductal carcinoma in situ and a positive regional lymph node?
For tumors diagnosed prior to 2007:
Code the Histology field to 8500/3 [Infiltrating duct carcinoma, NOS]. Code the EOD-Lymph Nodes field to 6 [Axillary/regional lymph nodes, NOS] and the SEER Summary Stage 2000 field to 3 [Ipsilateral regional lymph nodes(s) involved only].
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Multiple Primaries (Pre-2007)--Breast: Patient diagnosed with two lumps in same breast, different quadrants at same time. One was ductal carcinoma, cribriform type; the other was ductal carcinoma. How many primaries do we code? See discussion.
If the breast cancer had been diagnosed in 2000 we would have coded this case as one primary, code to higher ductal ca. For a 2001 or later diagnosis, should this be coded as two primaries?
For cases diagnosed 1998-2003:
Code this case as two primaries if the tumors are separate. Separate tumors have clear (negative) margins. If the tumors are not separate, code as one primary.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Prostate: Radical prostatectomy reveals two distinct tumors. One is "adenocarcinoma with ductal differentiation" and the other is "adenocarcinoma with acinar differentiation." What code is used to represent the histology and how many primaries does the patient have?
For tumors diagnosed 2001-2006:
This is one primary. Code the Histology field to 8255/3 [adenocarcinoma with mixed subtypes] based on rule A of the Coding Complex Morphologic Diagnoses. This is code was added in the ICD-O-3.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Grade, Differentiation--All Sites: Should we take the grade from a TNM staging form over a grade stated in a pathology report when the grade mentioned on the TNM staging form is a higher grade (e.g., Pathology report diagnosis is moderately differentiated adenocarcinoma, Gleason's 3+3=6, but the physician checked "poorly differentiated" on the TNM form)?
Code the Grade, Differentiation field to 2 [moderatley differentiated]. Code from the pathology report over the TNM staging form. If you do not have access to the path report, use the grade from the TNM form.
1) If Van Nuys nuclear grade 2 is the only grade given for an in situ breast primary, would it be coded as a 3-component system (e.g., 2/3 = 3)?
2) Is there a way of determining grade if only the total Van Nuys Prognostic index score is given (e.g., score 7/9)?
1. Code Van Nuys grade 2 as code 2 [Grade 2] in the Grade, Differentiation field.
2. Code Van Nuys score of 7 as 9 [Cell type not determined, not stated or not applicable] in the Grade, Differentiation field.
Currently, there is no conversion from the total Van Nuys score to grade because "grade" represents only one of the three Van Nuys factors that make up the total score. The other factors are tumor size and margin. The grade represents from 1 to 3 points within the total Van Nuys score. The total score can be between 3 and 9.
Scope of Regional Lymph Node Surgery/EOD-Number of Regional Nodes Examined: What codes is used to represent these fields when the surgeon states that a "lymph node dissection" was done, but no nodes are identified in the pathology report?
For cases diagnosed 1/1/2003 and after: Code the Scope of Regional Lymph Node Surgery field to 3 [Number of regional lymph nodes removed unknown or not stated; regional lymph nodes removed, NOS] and code the EOD-Number of Regional Nodes Examined field to 00 [No nodes examined].
The surgery fields reflect the procedures the physician performed. The EOD fields reflect the results of those procedures.
Reportability/Ambiguous Terminology--Breast: Should the American College of Radiology (ACR) BI-RADS assessment categories 4 [Suspicious Abnormality--biopsy should be considered] and 5 [Highly Suggestive of malignancy-appropriate action should be taken], impressions for mammograms and sonograms, be used as the sole basis for reportability? See discussion.
ACR website:
Category 4: Lesions that do not have the characteristic morphologies of breast cancer but have a definite probability of being malignant.
Category 5: lesions have a high probability of being cancer.
Multiple Primaries (Pre-2007)--Skin: If a patient presents with two separate lesions on the left cheek (i.e., left lateral cheek and left upper cheek) that both are histologically confirmed to be superficial spreading melanoma on the same day, is this coded as one or two primaries?
For tumors diagnosed prior to 2007:
Code as one primary.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
