For cases diagnosed 2007 or later:

When there is a single tumor in one lung and a single tumor in the other lung, apply rule M6 and abstract as multiple primaries. Use this rule whenever there is a single tumor in each lung, even when neither tumor is biopsied or resected.

This rule is unique to lung. Our physician advisors emphasized that it is very unlikely that a single tumor in one lung could be metastatic from a single tumor in the opposite lung. Therefore, the default is to abstract as multiple primaries.

The note at M6 means that there must be proof that one tumor is metastatic in order to abstract as a single primary. For example, a biopsy of the tumor proving that it is metastatic. An opinion or belief that one tumor is metastatic is not sufficient. In the absence of proof, use rule M6 and abstract as multiple primaries.

A list of MP/H clarifications will be available. This issue will be included on the list.

The best code available for this situation is 8153/3 [Gastrinoma, malignant].

Many pancreatic endocrine tumors produce more than one peptide, such as gastrin and somatostatin in this case. ICD-O-3 does not provide a code for pancreatic endocrine tumors which produce more than one peptide. According to the WHO Classification of Tumours of Endocrine Organs, there is a distinct hormonal syndrome associated with gastrin producing tumors, and not with many of the somatostatin producing tumors. Therefore, our pathologist consultant advises us to code to gastrinoma in this case.

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.In general, a measured area is not equivalent to a tumor size.

Do not apply the rule related to the breast example to other primary sites. This example in the CS manual pertains to coding tumor size for breast primaries when the size of the invasive component is not stated. In the example, the area involved with duct carcinoma in situ is the only measurement available. The size of the invasive component was not given.

For cases diagnosed prior to 1/1/2010:Assign code 9690 [Follicular lymphoma, NOS]. According to the WHO Classification of Lymphoid tumors, follicular lymphoma is a neoplasm of follicle center B cells which has at least a partially follicular pattern.

Assign code 9695 for follicular lymphoma grade 1, 9691 for follicular lymphoma grade 2, and 9698 for follicular lymphoma grade 3.

For cases diagnosed 1/1/10 and later, 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.

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.Code prostate CS Extension to 99 [Extension unknown] and code CS Tumor Size according to the information available from the surgery.

CS Extension code 95 [No evidence of primary tumor] should be used only in that rare situation when the only evidence of disease is distant mets or lymph node involvement, no primary tumor found. That is why CS tumor Size must be 000 when CS Extension code 95 is used.

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.Record the IPI score in SSF3 when the score is documented in the medical record. If the score is not stated, do not calculate it.

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.Code 80 can be used for positive lymph nodes when you are unable to determine if they are regional or distant. CS Lymph Nodes code 80 is provided for this situation in accordance with the downstaging rule.

Code 80 should be used very infrequently and only when there is no indication whether the involved lymph nodes are regional or distant.

Code the primary site as skin of breast when skin of breast is documented as the site of origin.

According to the WHO classification of soft tissue tumors, the majority of angiosarcomas "develop as cutaneous tumors...less than one quarter present as a deep soft tissue mass."

For cases diagnosed 2007 or later:

If you arrive at H21 and have an additional decision to make regarding the use of 8210, 8261 or 8263, you must make another pass through the histology rules. The second pass will determine which of the two or three histology codes to assign. The answer will vary depending of the specifics of the case.

Example:

Transverse colon: Adenocarcinoma in an adenomatous polyp involving muscularis propria and adenocarcinoma in a villous adenoma involving subserosa of transverse colon. Start with rule H15 because there are multiple tumors. Stop at H21 -- code either 8210 or 8261. To decide between 8210 and 8261, make a second pass through the histology rules, starting again with H15. Stop at H20. Code the histology of the most invasive tumor, 8210 [Adenocarcinoma in adenomatous polyp].
