  • The Accrual batch file format is based on the CTEP Clinical Data Update System (CDUS) file format. You can obtain a copy of the CDUS Instructions and Guidelines, which explains the CDUS file format in great detail, at the CTEP web site at http://ctep.cancer.gov/protocolDevelopment/electronic_applications/cdus.htm.

  • Although the CTRP accrual batch file format is CDUS-compatible, CTRP captures a subset of all the CDUS required data elements.  Comparison of CTRP and CDUS Accrual Data Elements provides a list of all the CDUS fields with a note next to each field indicating whether CTRP captures it.

  • Different data elements are required and expected when submitting accrual data to CTRP for Complete trials (National, Externally Peer Reviewed, and Institutional) than for Abbreviated Trials (Industrial). Instructions are provided below for preparing batch files for both Complete and Abbreviated Trials.

  • A CTRP accrual batch file is a TXT (.txt) file with fields delimited (separated) by commas. The text file can be UTF-8 or ANSI-encoded.

  • Each CTRP batch text file contains accrual data for a single trial. You can compress one or more CTRP accrual batch text files into a single Zip file and then upload this Zip file into CTRP. CTRP will unzip the file and process each TXT file. Your Zip file can include batch files for both Complete and Abbreviated Trials.

  • Only Super Abstractors can upload accruals for CTEP and DCP trials in the CTRP.
  • Upload accruals for CTEP and DCP trials via CTEP CDUS batch accrual files only.

Do not include the following items in Zip files that you intend to upload:

  • Folders or other Zip files
  • Path names. Some ZIP/compression tools provide an option to include the entire file path name when compressing a file. Path names describe the location of the file.

The first batch file will add new records.  Subsequent batch uploads will replace all existing data.  Batch uploads do not append data.  Please ensure batch files contain all accrual data for each site to date before uploading.
