For cases diagnosed 2001-2006:

Borderline tumors are not reportable to SEER as of 2001. If you are collecting them in your registry, use the following procedure: Exception 1 in the SEER Program Code Manual, 3rd Edition, responds to the issue of processing ovarian tumors. Simultaneously occurring ovarian tumors with a single histology are coded as one primary. In the case you cite, the right ovary primary occurred 7 months after the left ovary primary. This is not simultaneous, so it would be counted as a second 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.

For tumors diagnosed prior to 2007:

Code the case you describe as two primaries. The endometrioid adenocarcinoma can arise in the endometrium without a concomitant ovarian carcinoma.

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.

For tumors diagnosed prior to 2007:

Unless it is stated to be a RECURRENT or METASTATIC melanoma, record each melanoma as a separate primary when:

1. The occurrences are more than two months apart.

2. The fourth digit of the ICD-O topography code for skin [C44._] is different .

3. The first three digits of ICD-O-3 morphology code are different.

4. An in situ melanoma is followed by an invasive melanoma.

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.

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.

For tumors diagnosed prior to 2007:

Code as a single primary. Follow the guidelines in the SEER Program Code Manual for determining multiple primaries. Simultaneous multiple lesions of the same histologic type in the same site (same breast) are a single primary for SEER, even though the pathologist may perform special studies and state that the patient has more than 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.

For tumors diagnosed prior to 2007:

Accession as two breast primaries -- the first lobular ca in 1991; the second lobular and DCIS in 2002.

The differing histologies and the length of time between them negate the physician's designation as "recurrent" in this case.

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.

For tumors diagnosed prior to 2007:

Yes. These are two primaries.

In situ cancers are not included in SEER incidence rates. Incidence rates must correlate with mortality rates.

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.

Note: Answer verified Sept. 2019, still valid for current cases.

Code all mets at diagnosis fields to 0 when the Stage is I, II, or III.

When the lymphoma is Stage IV, one of the mets at dx fields (other than Mets at Dx-Distant lymph nodes) needs to be coded to 1. Stage IV indicates that there is multiple extralymphatic organ involvement, diffuse involvement of an organ; liver, brain, lung or bone involvement, or bone marrow involvement.

For bone, brain, liver, and lung, code these as 1 when these sites are involved and they are not the primary site. This is the same instruction for solid tumor neoplasms.

For mets at dx-distant lymph nodes, always code to 0. For lymphomas, lymph node involvement is included in stage and not based on whether they are regional or distant.

For mets at dx-other, code to 1 for bone marrow involvement or if there is multi extralymphatic organ involvement.

In a situation like this with one area of metastatic involvement and an unknown primary, if there is no further information, we advise that the metastasis are "regional" until/unless proven otherwise. With this in mind, code the Mets at Diagnosis fields as 0, including the Mets at Diagnosis--Distant Lymph Node(s). This case should continue to be worked up to identify the primary site. If a primary site is identified later, update the abstract accordingly. In the meantime, use text fields to describe the situation.

Marital Status is self-reported because the information is recorded in the medical record based on information obtained from the patient. Use text fields to document relevant information.

Examples

1. Assign code 2 for the first tumor and assign code 1 for the subsequent tumor unless the available information indicates the patient is divorced at the time of the subsequent tumor diagnosis. Patient may self-report single after a divorce. Assign code 4 in that situation.

The code assigned for marital status reflects the patient's marital status at the time of diagnosis for the tumor being abstracted. It is possible that marital status may be different for each tumor if the patient has multiple tumors.

2. If marital status is stated to be single, assign code 1.

3. If marital status is stated to be common law marriage, assign code 2.

Common Law Marriage is defined as a couple living together for a period of time and declaring themselves as married to friends, family, and the community, having never gone through a formal ceremony or obtained a marriage license.
