Breslow Tumor Thickness
This input is used for staging
Notes
**Note 1:** Physician statement of Breslow Tumor Thickness can be used to code this data item when no other information is available, or the available information is ambiguous. **Note 2:** Code Breslow tumor thickness, not size. Record actual measurement in tenths of millimeters from the pathology report. Measurement given in hundredths of millimeters should be rounded to the nearest tenth. * ***Examples:*** 0.4 mm - 0.4 1.0 mm- 1.0 2.5 mm - 2.5 2.56 mm- 2.6 11 mm - 11.0 12.35 mm - 12.4 **Note 3:** Code the greatest measured thickness from any procedure performed on the lesion, whether it is described as a biopsy or an excision. * For ***example,*** if a punch biopsy with a thickness of 1.5 mm is followed by a re-excision with a thickness of residual tumor of 0.2 mm, code 1.5. **Note 4:** If there are multiple procedures and the pathologist adds the measurement together to get a final Breslow’s depth, the registrar can use this. * Do not add the measurements together, only the pathologist can do this **Note 5:** If the pathologist describes the thickness as "at least," use the appropriate A code. An exact measurement takes precedence over A codes. * If the pathologist states "greater than" instead of "at least", code to XX.9, unless it is greater than 9.9 mm (Code AX.0) * ***Examples:*** Pathologist states the thickness is "at least 2.0 mm." Code A2.0 Pathologist states the thickness is "greater than 4 mm." Code XX.9Default
