For cases diagnosed 1998-2003:

Code the largest dimension mentioned, since that is the standard rule for coding tumor size. Keep in mind that tumor size is not used in analysis for certain sites such as stomach, colon & rectum, ovary, prostate, and urinary bladder. Tumor size is important for analysis for certain sites such as lung, bone, breast, and kidney.

For cases diagnosed 1998-2003:

Code "perivesical nodules" in the EOD-Lymph Nodes field as involvement of regional lymph nodes. Each gross nodule of metastatic carcinoma in the fat surrounding an organ is counted as one positive regional lymph node.

Cytology reported as "suspicious" is not reportable. If the physician confirms the suspicious cytology by making a clinical diagnosis of malignancy, the Date of Diagnosis field is coded to the date of the clinical diagnosis, which may or may not be same date the cytology was performed.

Without supporting clinical documentation, the case will remain non-reportable and will not be submitted to SEER. The supporting documentation can be a physician's statement that the patient has cancer, a scan or procedure that identifies cancer, or a positive biopsy.

Suspicious "biopsies" are reportable according to SEER's list of ambiguous terms. Suspicious "cytologies" without supporting clinical statements are not.

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.Use the information from the pathologic evaluation to code CS Lymph nodes.

In the nodes evaluation field, assign code 6 [Regional lymph nodes removed for examination with pre-surgical systemic treatment or radiation and lymph node evaluation based on pathologic evidence]. See CS Lymph Nodes note 4.

For tumors diagnosed prior to 2007:

Yes. This case is reportable as a second primary. The rule in the SEER Program Code Manual says that invasive bladder cancers with histology codes 8120-8130 [papillary, transitional] are always coded as a recurrence and are an exception to the multiple primary rule. Squamous cell carcinoma [8070] is not a part of that exception.

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.

Do not assign a behavior code of /2 to these cases unless you have a way to flag them so that they are not reported to the standard setters as in situ cases. Work with your state central registry to ensure that these cases are not unintentionally included in state case submission.

The CPC Validity Status of the site morphology combinations of C569/8441/3 and C569/8441/2 was revised from Valid to Unlikely with the latest release of the Version v24A Edits Metafile. As a result, this site and morphology combination will now require an over-ride flag to be set.

Code as 8461/3 (high-grade serous carcinoma) or 8460/3 (low-grade serous carcinoma) if at all possible. Use 8441/3 (serous carcinoma, NOS) only if it cannot be distinguished as low grade or high grade. The codes for high-grade serous carcinoma and low-grade serous carcinoma are relatively new. High-grade serous carcinoma and low-grade serous carcinoma are very different tumors and pathologists should state whether it is high grade or low grade. Please make every attempt to use the newer codes. If unable to determine high gade versus low grade, assign 8441/3 and override the edit.

The files on the CPC website are currently being updated, and CPC*Search will be updated to reflect the changes sometime this Fall.

For cases diagnosed 1998-2003:

Code the EOD-Lymph Nodes field to 6 [Axillary regional lymph nodes, NOS], if the size of the metastasis within the lymph node is not known. "Extension into perinodal soft tissue" does not imply that the lymph nodes are fixed to one another or to other structures. AJCC stage for lymph nodes is coded to N1 [Metastasis to moveable ipsilateral axillary lymph nodes].

In order to code the EOD-Lymph Nodes field to 5 [Fixed/matted ipsilateral axillary nodes] which is the equivalent to AJCC equivalent N2, there must be some clinical or pathologic statement of fixation or matting. There can be extension through the capsule without fixation or matting. "Fixation" is a clinical term and "matting" can be either clinical or pathologic. A pathologist can recognize two or more lymph nodes stuck together by tumor.

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 tumors diagnosed prior to 2007:

If the cancer at the anastamosis site is more than two months after the previous colon cancer, abstract as a separate primary.

If the cancer at the anastamosis site is within two months of the original diagnosis and the histologies are the same, do not abstract as a separate 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.
