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.

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

Surgical credentialing is also required for this protocol. Surgeons must be credentialed by their local institution to perform transoral eHNS (TLM or TORS) prior to enrolling patients on the trial. For more information, see section 5.5 of the protocol .

In order to complete the IMRT 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.

• This trial will utilize TRIAD for dosimetry digital treatment data submission. TRIAD is the American College of Radiology’s (ACR) image exchange application and it is used by the RTOG. See section 5.3 of the protocol for information on installing TRIAD.

• 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.
