Please fill out the credentialing status inquiry form to let us know that you would like to be credentialed for this protocol.

This study requires credentialing before patients can be entered onto this study. The credentialing requirements are different depending on whether you are using a 3D-CRT or IMRT technique. Institutions credentialing for IMRT will be fully credentialed for 3D-CRT.

This protocol requires each institution to submit electronic patient data to RTOG using TRIAD. For instructions on TRIAD, click here. Please note, with CTSU integration with TRIAD, IRB approval is required in order to submit credentialing data.

In order to complete the 3D-CRT credentialing process the following items must be completed:

• All participants are asked to update or complete a new IROC Facility Questionnaires

In order to complete the IMRT credentialing process, the following items must be completed:

• All participants are asked to update or complete a new IROC Facility Questionnaires

• Irradiate the IROC Houston's lung phantom using an IMRT technique. Please fill in the request form online

Note:

• Institutions that had irradiated the IROC Houston's H & N or prostate phantoms and are credentialed to participate in other RTOG IMRT protocols using same TPS and delivery technique still need to complete the Facility Questionnaires, however they are exempt from repeating the phantom irradiation if abdominal compression or Automatic Breathing Control (ABC) will be use as respiration control technique. If you would like to verify your previous credentialing status, please fill in the Credentialing Status Inquiry Form and someone from the IROC Houston will contact you.

• Institutions that have been successfully credentialed for prior RTOG lung SBRT studies will automatically quality for this study using the same delivery technique (3D-CRT vs IMRT) as previously credentialed for.

• The use of IGRT in this study is optional. In order to become credentialed for lung IGRT, the institution must have already become credentialed for 3D-CRT or / and IMRT. See the TRIAD web (TRIAD) for more information.
