EOD/Summary Stage--Eye: How is stage coded for a patient with extranodal non-Hodgkin lymphoma involving bilateral choroids (single focus, both sites) and no lymph node involvement? Since the eyes are a paired site, is this two separate extranodal sites? If so, there are no Summary Stage or EOD tumor codes that best fit this scenario.

EOD-Size of Primary Tumor: Should a 2.0 cm ulcerated mass be coded to 020 or 999 for tumor size? See discussion.

EOD-Size of Primary Tumor: Can the term "filling defect" be used to code tumor size? See Description.

EOD-Size of Primary Tumor/First Course Treatment--Breast: How is tumor size coded when preventative tamoxifen treatment precedes breast cancer diagnosis? Can we code the tumor size from the surgical specimen? Is tamoxifen treatment here? See Description.

EOD-Size of Primary Tumor/EOD-Extension--Breast: How do you code extension when the tumor in the breast is in situ and the regional axillary lymph nodes are positive? See discussion.

EOD-Pathologic Extension--Prostate: Is extracapsular extension implied by the phrase "tumor invades the fibrous tissue of the capsule"? See Description.

EOD-Lymph Nodes--Melanoma: Should we assume that positive lymph nodes are regional if the primary site for a melanoma is not identified (i.e., C449)?

EOD-Lymph Nodes--Lung: What code is used to represent this field when the only information is a description of:

1. "hilar mass"

2. "mediastinal mass"

3. "enlarged" or "greater than 1 cm" used to describe any of the lymph nodes listed under code 2 in the EOD Lymph Nodes field?

EOD-Lymph Nodes--Head & Neck: If a pre-treatment description of a chain of lymph nodes doesn't meet the criteria for involvement but the post-treatment description of the same chain of lymph nodes does, should those nodes be counted as involved in coding EOD? See Description.

EOD-Extension: The medical record lacks a clear statement that metastatic workup was complete. A metastatic deposit is identified within 4 months of diagnosis and while the patient is undergoing first course of treatment. How do you code the EOD-Extension field?
