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

Institutions that were previously credentialed to participate in another protocol will be notified if any additional credentialing steps are required.

For this study, IMRT is mandatory, and IGRT is optional. (IGRT is mandatory when using reduced margins)

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 IMRT credentialing process the following items must be completed:

• All participants are asked to complete the IROC Houston Facility Questionnaires.

• Irradiate the IROC Houston's IMRT H&N phantom.  Please fill in the request form online.

• Successfully complete the IGRT credentialing requirements if your institution plans to utilize PTV margins of less than 5mm. Details can be found here. (Click here for IGRT data spreadsheet).

Note:

Institutions that are credentialed to participate in other RTOG IMRT protocols requiring an IMRT H&N phantom irradiation need not repeat the phantom irradiation for credentialing for this protocol.
