EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined/Surgical Procedure of Other Site--Kaposi Sarcoma: How do you code these fields for a groin mass excision containing 4 lymph nodes for a Kaposi sarcoma case that presented with multiple skin lesions?
Code the EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined fields to 99 99 for Kaposi cases that present systemically and for those that present in more than one site (which includes cases with more than one skin subsite involved at diagnosis). There are no "regional" lymph nodes for such cases. This represents a majority of currently diagnosed Kaposi cases. However, for localized Kaposi cases, you can count the number of regional lymph nodes positive and examined if the primary site selected has a regional lymph node chain(s) associated with it (e.g., soft palate, hard palate, or a skin subsite).
For cases diagnosed 1/1/2003 and after: Code the groin mass excision in the Surgical Procedure of Other Site field to 1 [Non-primary surgical procedure performed; Non-primary surgical resection to other site(s), unknown if whether the site(s) is regional or distant].
EOD-Extension--Corpus Uteri: How do you code myometrial involvement described as 1) "to the level of the middle one-third" or 2) "superficial"?
For cases diagnosed 1998-2003:
Evaluate each case carefully.
1. Code the EOD-Extension field to 12 [Myometrium-inner half] because the pathology report indicates involvement of the myometrium "to the level of." However, if you feel that you cannot make that determination with certainty and you cannot ask a pathologist for clarification, then code the EOD-Extension field to 14 [Myometrium, NOS].
2. Code the EOD-Extension field to 12 [Myometrium-inner half] for cases with "superficial" myometrial invasion.
Extension/Ambiguous terminology: How should the terms "entrapped by tumor" and "encased by tumor" be interpreted when coding these fields?
Each case must be reviewed in its entirety to determine the appropriate coding of these fields. However, in general the terms "entrapped" and "encased" should NOT be interpreted as involvement unless there is other clinical or pathologic evidence to support involvement.
EOD-Extension--Corpus Uteri: What code is used to represent this field for a corpus primary (sounding 8 cm or less in length) treated with radiation prior to a hysterectomy that pathologically showed superficial myometrial invasion? Is it possible that the invasion could have been more extensive prior to the radiation treatment?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 12 [Myometrium, inner half] which represents the extension you know. In this particular case, there was no clinical evidence of extension outside the corpus. As long as the surgery was not performed because of disease progression, use information from the surgery to code EOD extension.
