Subject Accrual Data Elements for Abbreviated Trials

Topic Links

The tables in this section contain detailed information on each of the data elements included in the Batch Upload file. The first table provides values that are valid for the Batch Upload file. The CDUS Accepted Values in the second table are provided to show differences in values in case your system is already producing the CDUS file.

Use of CDUS Values


Although you can use CDUS values, they are being phased out in the CTRP. It is best, therefore, to use the CTRP values listed in the table below.


When you create a batch file, ensure that each data element conforms to the requirements.

  • List each data element in its appropriate position in a given row
  • Use the correct character cases (CAPITAL vs. lower case letters)
  • Use the correct character lengths (number of characters allowed in a single field)
  • If a comma is part of the value, enclose the field in double quotes. Otherwise the use of double quotes is optional.

Subject Disease Code



Code that identifies a disease

  • CTEP Simplified Disease Code (SDC) terms
  • ICD-9-CM codes
  • ICD-O-3 codes
  • ICD-10
For SDC Disease Code:
StudySubject / diease_identifier

For ICD-9 Disease Code:
StudySubject / icd9diease_identifier

Disease code is mandatory for all trials except those managed by DCP PIO.

Cancer specific ICD-9-CM disease codes in the range 140 to 239. Information about these disease codes is available at

Exit Disclaimer logo

For trials using ICD-O-3 terminology, use this position for Site and/or Histology Codes. When using both Site and Histology codes, separate them by a semicolon ( ; ). Site codes are available at

Use Histology codes when C codes are not available (for example, for Multiple Myeloma, NHL, Leukemia).

For uploading CDUS batch files, see the note below this table.

RaceMText for reporting information about race based on the Office of Management and Budget (OMB) categories
  • American Indian or Alaska Native
  • Asian
  • Black or African American
  • Native Hawaiian or Other Pacific Islander

Patient / raceCodeMultiple races in batch files are permissible even if "Not Reported" or "Unknown" is indicated.
Change CodeOAdditions or changes since the last report
  • 1
  • 2
  • NULL
AccrualCollections / changeCode

1 or NULL = changes in the file;  the CTRP system processes and saves the submission

2 = If the trial's current accrual is 0, the CTRP system processes the file as a Code 1 change. If the trial's current accrual is greater than 0, the system saves the file but does not process it.

For Super Abstractors uploading CDUS Accrual batch files


Use the following default disease codes when uploading a CDUS accrual batch file:

  • For patients missing the disease code
    • ICD-9: V100
    • SDC: 80000001
    • ICD-O-3
      • Site code: C998
      • Histology code: 7001
    • ICD-10: Z1000

Use the CTEP SDC "disease not specified code" 80000001 by default if the trial currently has NO existing patients, and all disease codes in the CDUS file are missing.
