For cases diagnosed 1998-2003:

Code the EOD-Extension field to 85 [Metastasis] because the tumor nodules are discontinuous from the primary tumor.

This answer pertains to cases prior to 2014. For cases diagnosed 2014 and forward, see http://seer.cancer.gov/tools/grade/

Do not use FIGO grade to code differentiation.

FIGO grade is something completely different from FIGO stage. FIGO stage is used to code EOD. FIGO grade is based on the percentage of non-squamous (i.e., solid) portions of the tumor and corresponds roughly to a three grade differentiation system: grade I, well differentiated (=<5% solid component); grade II, moderately differentiated (>5 - 50% solid); and grade III, poorly differentiated (> 50% solid). SEER is evaluating whether the ICD-O-3 6th digit differentiation codes (four grade categories) accurately represent the FIGO grade. For the time being, do not code FIGO grade.

For a diagnosis that includes commonly used differentiation term with a FIGO grade, such as "Moderately differentiated, FIGO grade II," disregard the FIGO grade and code the Grade, Differentiation field according to the term "Moderately differentiated."

For tumors diagnosed prior to 2007:

Yes. Code the Histology and Grade, Differentiation fields to 8070/33 [poorly differentiated squamous cell carcinoma]. Code the higher grade when different grades are specified for the same specimen and code the more specific morphology (i.e., squamous cell carcinoma rather than carcinoma, NOS).

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 cases diagnosed 1998-2003:

Code the EOD-Lymph Nodes field to 1 [Micrometastasis] because the matted nodal tissue was found to contain only one node with micrometastasis when examined microscopically. Coding priority is given to the microscopic description over the gross description.

For tumors diagnosed prior to 2007:

Yes. This is one primary and should be coded to C49.5 [Connective, subcutaneous and other soft tissue of pelvis]. According to Rule A in ICD-O-3, the type of tumor ("sarcoma") indicates origin from a particular tissue, resulting in the primary site code of C49.5 [Inguinal region, NOS] for this sarcoma.

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 cases diagnosed 1998-2003:

The total number of lymph nodes examined is recorded in EOD-Num of Reg LN Examined. If the number of actual lymph nodes represented by the "fragments" or "portions" cannot be determined, assign code 96, 97, or 98 as appropriate.

1) Based on the terminology "four portions of lymph node (singular)" code to 01 despite "dissection" terminology.

2) Code to 97 based on "fragments of lymph nodes (pleural)" terminology and procedure identified as dissection.

3) Code to 97 based on statement of "fragments of lymph nodes (pleural)" for biopsy plus dissection.

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 primary site cervix uteri, only histologies with behavior codes of 3 [invasive] are reportable to SEER for all registries.

Some SEER registries have opted to continue to collect behavior codes of 2 [in situ] for cervix uteri primaries.

For tumors diagnosed prior to 2007:

Code the Histology field to 8263/3 [adenocarcinoma in a tubulovillous adenoma]. Because the mucinous component involves less than 50% of the tumor, the histology is not coded to mucinous. For mucinous only, the tumor must be at least 50% mucinous, mucin producing, to be coded to the specific histology.

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 Histology field to 8830/3 [Malignant fibrous histiocytoma]. Code the Date of Diagnosis to October 1999 based on the clinician's statement of "The patient probably has malignant fibrous histiocytoma. His course has been more aggressive than that seen with an atypical fibroxanthoma." Assume that this statement means that the physician re-evaluated the clinical course and decided that the original tumor must have been malignant.

If the original slides are reviewed and the diagnosis is changed to a malignancy or if the clinician states that the first occurrence was obviously malignant, backdate the date of diagnosis to the first occurrence.

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.
