First Course Treatment--All Sites: The patient has undergone part of the planned first course of treatment when a metastatic deposit is identified. If the patient continues with the planned first course of treatment, should the modalities of treatment given after the metastatic deposit is discovered be included in the coding of the first course of cancer-directed treatment fields?

Yes, those modalities should be counted as part of first course of cancer-directed treatment if the patient continues with the planned first course. For example, if patient has the originally planned type of surgery, radiation, or drug protocol, then code the given treatment as first course.

Caution: It is not a change in the treatment plan if the drugs are changed but the action of the drugs remains the same. This is still first course. However, if the treatment is changed from a chemotherapy drug to a hormonal drug following the discovery of the mets, do not code the hormonal therapy as first course.

Multiple Primaries (Pre-2007)--Breast: When two breast tumors with two different histologies, such as duct and mucinous are diagnosed in the same breast at the same time, are they reportable as two primaries? See discussion.

Our rule is that multiple lesions of different histologic types are separate primaries. However, for separate tumors of duct and lobular, we report as a single primary. Since we now have a combination code for duct and other types of ca, do we report as a single primary or continue to report as separate primaries?

For tumors diagnosed prior to 2007:

When there are two breast tumors, one mucinous, the other duct carcinoma, report as two primaries when the pathologist's opinion clearly states that there are separate primaries.

If there is no such information from the pathologist, the two tumors must be separate with clear (negative) margins to be reported as two primaries. Otherwise, report as one primary.

The ICD-O-3 combination codes are not intended to combine tumors of different histologic types.

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.

20021028 EOD-Clinical Extension--Prostate: If the tumor arises in the prostatic apex, does that take priority over coding clinical extension based on the stage of cT1c? See discussion. Physician states prostate primary is a cT1c. Pathology states adenocarcinoma, Gleason 3+3, right apex. All other biopsies were negative. Because the primary appears to be in the prostatic apex, do we code 33 or 15 for clinical extension? Which is more important for SEER? Do you want to capture the "apex" information or the "cT1c" information?

For cases diagnosed 1998-2003:

Code the EOD-Clinical Extension field to 33 [arising in prostatic apex]. Apex information takes priority. The only statement we have is cT1c by the urologist, and we don't know how that stage was determined.

20020016 Primary Site (Pre-2007)--Prostate/Prostatic Urethra: What code is used to represent primary site for an "adenocarcinoma with spindle cell differentiation" of the prostatic urethra?

For tumors diagnosed prior to 2007:

Code the Primary Site field to C61.9 [prostate] because the histology is adenocarcinoma.

When a malignancy is identified in the prostatic urethra, look at the histology to determine the primary site. If it is a transitional cell carcinoma, code the Primary Site field to C68.0 [urethra] and if it is an adenocarcinoma, code to C61.9 [prostate].

The EOD scheme is ultimately collapsed into the TNM scheme. The TNM system differentiates between adenocarcinoma of the prostate and transitional cell carcinoma of the urethra. Only adenocarcinoma of the prostate is staged by the prostate scheme. Transitional cell carcinoma of the prostatic urethra is coded to C68.0 [urethra] and staged with that scheme.

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.

20021015 Ambiguous Terminology/Reportability: How should the expressions "suspicious for but not diagnostic of" and "suspicious for the possibility of early invasive adenocarcinoma" be interpreted for reportability? Would the interpretation be different depending on the primary site?

For reportability, interpret "suspicious for but not diagnostic of" as NOT diagnostic of cancer.

The phrase "suspicious for the possibility of early invasive adenocarcinoma" may indicate that the case is in situ. If no further information is available, this is not reportable.

The site of the cancer diagnosis does not change the interpretation.

20021077 Histology (Pre-2007)/Primary Site/EOD-Extension--All Sites: How do you code these fields for a resected thyroid that is negative for any diagnostic abnormality and a left ovary that demonstrates "papillary thyroid carcinoma arising in a cystic teratoma"? See discussion. Teratomas occurring in the ovaries frequently contain various types of fully differentiated tissue that normally occur in other body parts. Should the primary be coded to the ovary or to the organ in which that type of tissue normally occurs?

For tumors diagnosed prior to 2007:

Code the Primary Site field to the organ in which the cancer arose. For this tumor, code the Primary Site field to C56.9 [ovary] and Histology to 8260/3 [papillary carcinoma of thyroid]. Use the ovary EOD for tumors diagnosed 1998-2003.

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.

20020049 EOD-Extension--Breast: Should clinically mentioned "thickening" of the breast be ignored if the pathology report does not mention thickening or skin involvement? See discussion. For cases diagnosed 1998-2003: Can clinical "thickening" of the breast be coded to 20-28 extension code when there is no mention of the thickening or skin involvement in the pathology report? How do we code cases when pathology reports don't support the clinical finding of skin involvement. For cases diagnosed 1998-2003: Do not use code 20-28 when there is no preoperative treatment and the pathology report does not confirm skin invasion. The clinical diagnosis of skin involvement was not supported by the pathology report. 2002
20021059 Surgery of Primary Site--Soft Tissue: What code is used to represent this field when an excisional biopsy of a soft tissue sarcoma is followed two weeks later with a wide excision (re-excision)? For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 26 [partial resection]. According to the CoC, "Excision" in the surgery codes refers to the lesion and "partial resection" refers to the organ. The biopsy is a local excision (code 25). The wide resection is code 26, presuming that more than just the remaining lesion was removed. 2002
20021118 Grade, Differentiation--Lymphoma/Leukemia: Should the term "Pre-T" be added to code 5 [T-cell] in the ICD-O-3 Table 22, 6th Digit Code for Immunophenotype Designation for Lymphoma and Leukemia?

For cases diagnosed prior to 1/1/2010:Code the Grade, Differentiation field to 5 [T-cell] in the 6th digit of the ICD-O-3 morphology field when the terms "pre-T cell" or "T-precursor" are used. However, this is not an official change to ICD-O-3.

For cases diagnosed 2010 forward, 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.

20020012 MP/H Rules/Histology--Breast: What code is used to represent the histology "ductal carcinoma in situ and invasive lobular carcinoma"? See discussion. Is the histology coded to the combination code of 8522/3 (ductal and lobular) or to the invasive component 8520/3 (lobular)?

For cases diagnosed 2007 or later:

Assuming ductal carcinoma in situ and invasive lobular carcinoma are present in a single tumor, code 8520/3 [Infiltrating lobular carcinoma, NOS].

Using the 2007 MP/H rules for breast, the single tumor invasive and in situ carcinoma module, start and stop at rule H9 and code the invasive histology.
