Assign histology code 9505/1 [Ganglioglioma, NOS].

Rosette-forming glioneuronal tumor of the 4th ventricle is a new WHO entity. There is no current ICD-O-3 code for this. The best code available at this time is 9505/1.

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 SSF 3 for lymphoma based on the IPI score stated in the record. Do not attempt to interpret statements or terms in order to assign a code to SSF 3. If no further information is available for this case, code SSF 3 999 [Unknown].

For cases diagnosed 2007 or later, this is four primaries.

Report NF2 because it occurs with reportable neoplasms. Note: Report NF only once per patient.

Per MP/H Benign CNS Rule M4, the meningiomas of the meninges/brain (C70.0) and meninges/CNS (C70.1) are multiple primaries. Code the meningiomas of the spine to the histology to 9530/1 [Multiple meningiomas] (Rule H6) because there are multiple tumors in the spine.

Per Rule M5, the meningiomas of the right and left side of the brain are multiple primaries. Code of each to the histology 9530/0 [Meningioma, NOS] per Rule H2 because they are separate primaries (assuming there is one tumor on each side of the brain).

A tumor that is non-reportable based on the pathology report diagnosis should not be accessioned if later clinician statements mistakenly refer to it as a reportable tumor. The exception in the 2007 SEER manual on page 3 is intended to allow the registrar to accession a case when the clinician actually disagrees with the pathology report and clinically diagnoses a reportable tumor.

For cases diagnosed 2007 or later:

Follow MP/H Other Sites Rule H11 and code 8144/3 [Adenocarcinoma, intestinal type]. Adenocarcinoma, intestinal type, is called that because it resembles the normal pattern of adenocarcinoma seen in the large intestines. It is not an indication of the location of the adenocarcinoma. We find that it is not uncommon in the sinuses, stomach, lungs, cervix, and many other organs.

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 regional lymph nodes positive 01 [one positive lymph node] and regional lymph nodes examined 01 [one lymph node examined] (assuming the positive node was the only node examined).

If the only lymph node involvement is the positive axillary lymph node, it is reasonable to conclude that this is a regional lymph node. When only one chain of lymph nodes is involved with metastatic melanoma, the metastatic cells had to come from skin with direct drainage to those lymph nodes.

For cases diagnosed 2007 or later, this is two primaries.

MPH General Instructions tell us a pathologist may decide when there is recurrence when comparing the current tumor to a previous specimen. In this case, the pathologist did the comparison and documented that the second tumor is NOT a recurrence but a new primary.

Histologies described by the terms "pattern" and "component" do not indicate a more specific type when applying the histology rules. The histology for the 2009 diagnosis is adenocarcinoma [8140/3]. Rule H3 applies.

For cases diagnosed 2007 or later, the 2007 MP/H rules apply if the 2008 diagnosis is a new tumor. Was there any statement that the patient was free of disease (NED) after the chemo and radiation therapy? (A patient can be disease free without surgery). If there is no statement to the contrary, no mention of metastasis from the 1998 diagnosis, and no mention of disease between 1998 and 2008, follow lung rule M8 and abstract the 2008 diagnosis as a new primary.

This lung case differs from the colon case discussed in the document titled "Quality Improvement Meeting August 2008." For the colon case, there was disease in 2003, 2005 and 2007. Based on the information provided, the 2007 diagnosis was not a new tumor because the patient was never free of disease. Therefore, the 2007 diagnosis is not a new primary. The number of reportable primaries was based on disease status over time, and was not based on the type of treatment given for the initial tumor (i.e., surgery or any other treatment modality).

For cases diagnosed 2007 or later:

For a pleural or fallopian tube primary, if there is tumor(s) on the left and separate tumor(s) on the right and neither is stated to be metastatic from the other, abstract as multiple primaries according to rule M8 for other sites. If both sides are involved, but there is only one tumor, rule M2 for other sites applies and this is a single primary. Code each primary separately in CS.

For cases diagnosed 2007 or later, Rule M11 applies. Accession two primaries.

Rule M10 applies only to cases for which one tumor is stated to be "non-small cell carcinoma."
