1. Code Van Nuys grade 2 as code 2 [Grade 2] in the Grade, Differentiation field.

2. Code Van Nuys score of 7 as 9 [Cell type not determined, not stated or not applicable] in the Grade, Differentiation field.

Currently, there is no conversion from the total Van Nuys score to grade because "grade" represents only one of the three Van Nuys factors that make up the total score. The other factors are tumor size and margin. The grade represents from 1 to 3 points within the total Van Nuys score. The total score can be between 3 and 9.

For tumors diagnosed prior to 2007:

Code "Infiltrating duct and mucinous carcinoma" to 8523/3 [Infiltrating duct mixed with other types of carcinoma] according to the instructions for coding a single tumor with complex histology in Appendix C of the 2004 SEER manual. Assign code 8523/3 when the diagnosis is duct carcinoma mixed with another type of carcinoma. Look for "and" or "mixed" in the diagnosis.

Code the Histology field for a "ductal carcinoma, mucinous type" to 8480/3 [Mucinous carcinoma].

The instructions for coding a single tumor with complex histology are to code the specific type if the diagnosis is "Duct carcinoma, _____ type."

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:

Yes. Use the scheme on page 180 for MALT lymphoma. The ICD-O-2 morphology code 9715 was omitted in error. It should have been added when the EOD was printed in 1998.

For tumors diagnosed prior to 2007:

If there is no mention of endometrioid carcinoma in the microscopic description, code the Histology field to 8500/3 [duct carcinoma]. If "endometrioid carcinoma" is mentioned in either the final diagnosis or in the microscopic description, code the Histology field to 8380/3 [endometrioid carcinoma].

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 between 1998-2003:

Code the EOD-Lymph Nodes field to 3 [Mesenteric, NOS]. Mesocolic lymph nodes are coded as mesenteric lymph nodes.

For tumors diagnosed prior to 2007:

Code the Histology field to 8500/3 [Infiltrating duct carcinoma, NOS]. Code the EOD-Lymph Nodes field to 6 [Axillary/regional lymph nodes, NOS] and the SEER Summary Stage 2000 field to 3 [Ipsilateral regional lymph nodes(s) involved only].

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 8480/3 [mucinous adenocarcinoma] using rule D in the Coding Complex Morphology Diagnoses: "Code the morphology with the highest code."

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 to 40 [extension to peripancreatic tissue, NOS]. Neither of the terms "extending around" nor "encasing" are interpreted as involvement with tumor by SEER.

Myelodysplastic syndrome cases with unknown dates of diagnosis identified in pre-2001 casefinding documents should not be accessioned and are not SEER reportable.

For cases identified in 2001 casefinding documents, when the diagnosis date cannot be confirmed using the medical records typically accessed by the registrar or central registry staff, do not accession these cases; they are not SEER reportable. This default applies only to those cases identified in 2001 casefinding documents.

For cases identified in 2002 or later casefinding documents, the attending physician should be contacted and asked to clarify the diagnosis date for cases identified with unknown dates of diagnosis. Clarifying the diagnosis date is necessary to determine whether the case is reportable and whether it should be accessioned.

For cases diagnosed 1998 and later:

Code the Surgery of Primary Site field to 17 [Other method of local tumor destruction]. HIFU uses focused energy to destroy tissue. It is classified as a surgical procedure.
