Collaborative Stage

Collaborative Stage for TNM 7 - Revised 12/31/2009 [ Schema ]

CS Site-Specific Factor 1
Measured Thickness (Depth)

Note 1: Code MEASURED THICKNESS (Depth) of tumor, not size. Recording of depth for Merkel cell carcinoma of skin is similar to Breslow's tumor depth in melanoma of the skin. Record the actual measurement in tenths of millimeters from the pathology report.
Note 2: If tumor was reported as transected by pathology and depth was determined record the measurement below and note in SSF2 that tumor was transected.
Note 3: If tumor is in-situ (CS Extension code 000), code measured thickness 999.

Code	Description
000	No mass/tumor found
001-979	00.1 - 97.9 millimeters Code exact measurement in TENTHS of millimeters. Examples: 001 0.1 millimeter 002 0.2 millimeters 010 1 millimeter 074 7.4 millimeters 100 10 millimeters, 1 centimeter 105 10.5 millimeters 979 97.9 millimeters
980	98.0 millimeters or larger
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.)
990	Microinvasion; microscopic focus or foci only and no size given
998	No histologic examination of primary site
999	Unknown or no information Not documented in patient record Unknown; depth not stated
