Collaborative Stage for TNM 7 - Revised 07/19/2011 [ Schema ]

CS Site-Specific Factor 5
Distance to Distal Edge of Tumor from Incisors

Note 1: The distance from the incisors to the distal edge of the tumor is collected in this Site-Specific Factor. The location of the tumor's distal edge within the esophagus may be described based on imaging, esophagoscopy, or surgical results.
Note 2: Record the distance from the incisors to the distal edge of tumor to the nearest centimeter (cm).
Note 3: Calculate the distance to the distal edge of tumor if the distance to the proximal edge and the length of the tumor is known.

Code	Description
000	OBSOLETE DATA REVIEWED AND CHANGED V0203 "Involved" edge distance is not appropriate. Code distance to the distal edge of the tumor as described in the Notes, or use code 999 if distance unknown. Distal edge of tumor involved
001-060	1 - 60 centimeters (cm) (Exact distance from incisors to distal edge of tumor to the nearest centimeter.)
888	OBSOLETE DATA CONVERTED V0200 See code 988 Not applicable for this site
988	Not applicable: Information not collected for this case (May include cases converted from code 888 used in CSv1 for "Not applicable" or when the item was not collected. If this item is required to derive T, N, M, or any stage, use of code 988 may result in an error.)
