Institutions that were previously credentialed to participate in another protocol or have a question about your status for this protocol, please fill out the credentialing status inquiry form.

This study requires credentialing before patients can be entered onto this study. The credentialing requirements are different depending on whether you are using a 3DCRT or IMRT technique. You can be credentialed for either technique or for both depending on your physician's treatment preference.

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

• All participants are asked to complete and fax/e-mail the Facility Questionnaires to RTOG at 215-940-8817 or rtog-facquest@phila.acr.org. Questions about the questionnaires can be directed to Tammy McGlade at 215-574-3219.

• Submit an actual patient treatment plan digitally to the ATC.

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

• Complete and submit the Facility Questionnaires to RTOG.

• Submit an actual patient treatment plan digitally to the ATC.

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

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.
