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.

"Erosion" is not synonymous with "ulceration" when coding CS extension for breast.

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.

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.

Code Radiation (Rx Summ--Radiation) to 0 [None; diagnosed at autopsy].

SEER does not collect the Reason For No Radiation field. However, those who abstract using software that captures this data item can identify these cases. Code 5 [radiation not administered because patient died] reflects this situation.

Radiation (Rx Summ-Radiation) is a SEER field. This field is derived from the data collected in Rad-Boost Rx Modality and Rad-Regional TX Modality. These fields do not include a choice for "radiation not given because the patient died prior to treatment." Therefore, this information cannot be coded in the Radiation field.

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." Go to the SEER website to view this session http://www.seer.cancer.gov/tools/mphrules/training_advanced.html

For cases diagnosed prior to 1/1/2010:Code CMML for this case. Code the histology at initial diagnosis. This patient had rapid progression, but the initial diagnosis was "more compatible with CMML/MPD."

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.

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]

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.

For cases diagnosed prior to 1/1/2010:This case is not reportable at this point. A lymphoid component is not equivalent to a diagnosis of a reportable disease. In order to be a malignant, reportable disease, the condition must be monoclonal and irreversible. Cytogenetics were negative for malignancy (i.e. no monoclonal abnormality identified which is the criteria used to establish this diagnosis). Use all information available when determining reportability.

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.

For cases diagnosed 2007 or later, code acinar adenocarcinoma of the prostate as 8140/3.

Prior to diagnosis year 2007, code 8550/3 [acinar adenocarcinoma] may be used for prostate cases and for acinar adenocarcinoma of other sites, such as pancreas.
