Site-Specific Factor 1
Measured Thickness (Depth)
Notes
**Note 1:** Code measured thickness (depth) of tumor, not size. Depth for Merkel cell carcinoma of skin is similar to Breslow tumor depth in melanoma of the skin. * Record the actual measurement in tenths of millimeters (mm) from the pathology report **Note 2:** If tumor depth is noted on multiple specimens (two or more), record the greatest vertical or depth measurement noted on a single specimen; do not add measurements together. * Record in **Site-Specific Factor 19, Tumor Base Transection Status** that the tumor was transected **Note 3:** If tumor is in situ (pTis), code measured thickness as 999.Default
