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

EOD-Pathologic Extension--Prostate: Is extracapsular extension implied by the phrase "tumor invades the fibrous tissue of the capsule"? 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-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: Can the term "filling defect" be used to code tumor size? See Description.

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

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.

Extent of Disease/EOD Regional Nodes--Small Intestine: For an ileal/jejunal neuroendocrine primary, how should mesenteric soft tissue deposits (less than 2 cm) be collected in Extent of Disease (EOD) Staging? See Discussion.

First Course of Therapy--Heme & Lymphoid Neoplasms: How is first course of treatment coded for hematopoietic and lymphoid neoplasm (heme) cases who are put on surveillance for years while asymptomatic and then start chemotherapy or other treatment years later once they become symptomatic? See Discussion.
