For cases diagnosed 1998-2003:

Code the EOD-Extension field to 75 [Peritoneal implants, NOS] because the size of the implants on the omentum is not known.

Note 6 was added to the EOD scheme which states that both direct extension and discontinuous metastasis to the omentum are coded in the range 70-75 depending on how the peritoneal implants are described.

For cases diagnosed 1/1/2003 and after: A bone marrow transplant can be first course of therapy for cases in which there has been no progression of disease between the initial therapy (e.g., surgery, radiation, chemotherapy) and the bone marrow transplant. Code Hematologic Transplant and Endocrine Procedures field to 10-12 or 40 (depending on the type of bone marrow transplant performed).

Do not use leukemia treatment time guidelines when coding breast cancer treatment.

For tumors diagnosed prior to 2007:

Code the Histology field to 8261/3 [adenocarcinoma in a villous adenoma]. In describing colon polyps, papillary and villous are equivalent terms.

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-Extension field for both cases to 40 [Tumor limited to larynx WITH vocal cord fixation]. Code 35 [Impaired vocal cord mobility] implies that mobility is diminished in strength and/or quality but is not rigid. Impaired mobility is a T2 tumor. Because the second case is T3, the physician implies he/she is using the term "immobility" to describe complete fixation.

For cases diagnosed 1998-2003:

No. Do not use the SEER Summary Stage Guide or any other guide to derive an estimated Clark's level from the thickness identified in the pathology report. The two measurements need to come directly from the pathology report. Each is coded separately in EOD. Thickness is collected in a separate field so we can capture the actual measurement stated in the pathology report. This has made it possible for us to group depth of invasion for analysis purposes in any manner we might wish. In addition, we can always collapse this information to the Summary Stage or TNM using the AJCC rules. AJCC rules use both depth of invasion and thickness in determining pathologic staging, and, if there is an inconsistency between them, the rules say code to the higher T classification, that is, the least favorable finding.

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 30 [Localized, NOS], unless more information is known about the extent of tumor involvement. Coding the Histology field to 8142/3 [Linitis plastica] and the Size of Primary Tumor field to 998 [Diffuse; widespread; 3/4 or more: Linitis plastica] identifies this diagnosis.

In the EOD-Extension field, the depth of invasion is the important characteristic to be coded. The 10 digit EOD corresponds to the AJCC Staging Manual in which the "T" is based on level of invasion. While a diagnosis of linitis plastica indicates a worse prognosis, it does not define the extent of infiltration. There is no luminal mass with linitis plastica. Instead, the entire gastric wall is thickened by tumor.

For cases diagnosed 1998-2003:

When the prostate feels benign and the cancer is found incidentally at the time of the microscopic exam, code the EOD-Extension field to 10 [number of foci or % of involved tissue not specified]. Code as 13 (less than or equal to 5%) or 14 (greater than 5%) if percentage involved is given in the tissue resected. If the path report states "solitary focus of carcinoma" without mentioning the total amount of tissue resected, code extension to 13. If there is more than one focus, code extension to 10. Don't assign a code of 20 unless the tumor is clinically apparent.
