20061001 2004 SEER Manual Errata/CS Lymph Nodes--Head & Neck: On page C-353, in the supraglottic larynx schema, there is no mention of Level IV nodes in the CS Lymph Node codes.

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.The CS Steering Committee is aware of this issue and is working to resolve it.

Submit all CSv2 questions to the CoC Inquiry and Response System (http://web.facs.org/coc/default.htm).

20061015 2004 SEER Manual Errata/CS Site Specific Factor: Does SEER plan to incorporate the "Recording Tumor Markers in Collaborative Staging System Site-Specific Factors" document that was prepared for the CS Task Force Training Materials into the 2006 SEER Manual?

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.

There are no plans at this time to incorporate the Recording Tumor Markers document into the SEER manual. This document is not part of the Collaborative Staging manual. This is a stand-alone reference endorsed by the Collaborative Staging Steering Committee for use in coding site-specific tumor markers.

20051135 2004 SEER Manual Errata/CS Tumor Size--Can the Determining Descriptive Tumor Size information, on page 6 in the SEER EOD Manual, January 1998, be used to code descriptive tumor size in Collaborative Stage?

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 instructions in the CS Manual, Appendix 1, page 62. This information will be added to the 2004 SEER manual in the next update.

Do not use the Determining Descriptive Tumor Size information from EOD for CS Tumor Size.

20051039 2004 SEER Manual Errata/Cancer-Directed Therapy: Is the phrase "cancer directed therapy" still applicable? Remove the phrase "cancer-directed therapy" from pages 174 and 175 of the 2004 SEER manual.
20051089 2004 SEER Manual Errata/Grade--Breast: Are the codes on page 94 of the SEER manuals Breast Grading Conversion Table requiring conversion of nuclear grades 1/3 and 1/2 to code 1, 2/3 to code 2, and 2/2 and 3/3 to code 3 correct or are the codes on page C-473 in the Three-Grade System (Nuclear Grade) for breast correct that requires conversion of the same examples to codes 2, 3, and 4 respectively? On page C-473: Delete the section titled "Three-Grade System (Nuclear Grade)" and delete the table. Use the tables on pages 94 and C-472 to code grade for breast cancer. This correction will be made in the next errata.
20051082 2004 SEER Manual Errata/Grade--Colon/Bones: Is the term "pleomorphic" used to code tumor grade to 3 for selected primaries? Delete the row containing the word "pleomorphic" from the tables on pages 93, C-219 and C-411. This correction will be included in the next set of replacement pages for the 2004 SEER manual.
20051088 2004 SEER Manual Errata/Surgery of Primary Site--Lymphoma: Item 9.a on page 178 is incorrect. Do not assign surgery code 98 to lymphoma, primary in lymph nodes. See Appendix C, page C-707 for Lymphoma (primary in lymph nodes) surgery codes. Delete item 9. a. i. ii. and iii. on page 178 of the 2004 SEER Manual. This correction will be included in the next errata.

2018 EOD Primary Tumor/2018 EOD Mets--Lung:Is EOD Primary Tumor coded to 500 and EOD Mets 10 when there are bilateral lung nodules with nodules in same lobe as the primary tumor? How is EOD Primary Tumor coded when separate tumor nodes are in an ipsilateral lung but there is no documentation as to whether it is in the same or different ipsilateral lobe from the primary tumor?

Assign 999 to EOD Primary Tumorif this is the only information you have for your case.The mention of nodules does not automatically mean that you have separate tumor nodules. There are many reasons for the appearance of nodules in the lung, some of which are not due to cancer. Unless you have further information on whether the physician has determined that they are related to the lung cancer, then assume that they are not related.

Assign 00 to EOD Mets. Do not code EOD Mets to 10 since you cannot determine whether those nodules are based on the tumor or not.

If you are able to obtain more information, then you can update the EOD Primary Tumor and EOD Mets.

Regarding the second question, ifseparate tumor nodules are noted, you cannot assume that they are due to tumor. Further information, or clarification, is needed on whether the separate tumor nodules are related to the lung cancer. Without further information, code EOD Primary Tumor to 999.

There is also some information in the CAnswer Forum since Separate Tumor Nodules are a Site-Specific Data Item: http://cancerbulletin.facs.org/forums/forum/site-specific-data-items-grade-2018/96061-lung-separate-tumor-nodules

2018 Solid Tumor Rules/Histology--Colon:What is the histology code of a diagnosis of well differentiated neuroendocrine tumor (NET), grade 2 of the appendix? See Discussion.

SINQ 20160023 and the Solid Tumor Rules indicate NET G1 (or well differentiated NET) is coded as 8240 and NET G2 is coded as 8249.

Clarification regarding grade coding in the CAnswer Forum indicates well differentiated neuroendocrine tumor refers to the histologic type, and not the grade. Therefore, the term well differentiated is ignored for the purpose of grade coding.

Neither of these sources clarifies how to code histology for a tumor diagnosed as well differentiated neuroendocrine tumor, grade 2.

Assign histology code 8249 for histology described as well differentiated NET G2.A synonym for NET of the appendix includes well-differentiated endocrine tumor/carcinoma according to WHO Classification of Tumors of the Digestive System, 4th edition. "Well differentiated" could apply to eitherNET G1 or NET G2.
