Collaborative Stage

Note 1: According to AJCC pathologic tumor size is an important prognostic factor. The three dimensional tumor size (length, width and height) is also an important factor that will be collected if recorded in the pathology report. The general CS Tumor Size will be the place holder for the largest tumor dimension of tumor size. Record the second largest dimension of tumor size in SSF1 and the smallest dimension of tumor size in SSF 2. Only record from pathology report, do not use clinical imaging sizes.
Note 2: Record size as recorded in pathology report. Tumor size recorded as 3.0 cm x 4.0 cm x 2.0 cm is recorded as follows: CS Tumor Size table as 040 Site-specific Factor 1 Tumor Size Second Dimension as 030 Site-Specific Factor 2 Tumor Size Third Dimension as 020.
