DD_category: 
PUF Data Item Name: 
RAD_REGIONAL_DOSE_CGY
NAACCR Item #: 
1510
length: 
5
Allowable values: 
00000 – 88887, 88888, 99999
Description: 
Records the dominant or most clinically significant total dose of regional radiation therapy delivered to the patient during the first course of treatment. The unit of measure is centiGray (cGy).
Registry Coding Instructions: 
  • The International Council for Radiation Protection (ICRP) recommends recording doses at the axis point where applicable (opposed fields, four field box, wedged pair, and so on). For maximum consistency in this data item, the ICRP recommendations should be followed whenever possible. Where there is no clear axis point, record the dose as indicated in the summary chart. Determining the exact dose may be highly subjective and require assistance from the radiation oncologist for consistent coding.
  • Regional dose will typically be found in the radiation oncologist’s summary letter for the first course of treatment. Determination of the total dose of regional radiation therapy may require assistance from the radiation oncologist for consistent coding.
  • Do not include the boost dose, if one was administered.
  • Code 88888 when brachytherapy or radioisotopes—codes 50–62 for Regional Treatment Modality (NAACCR Item #1570)—were administered to the patient.
  • Note that dose is still occasionally specified in “rads.” One rad is equivalent to one centiGray (cGy).
Analytic Note: 

This item is reported as an optional item per the ROADS manual for cases diagnosed between January 1, 1996 and December 31, 2002, and required thereafter.
