Purpose/Objective:

Adaptive radiotherapy (ART) in radical treatment of patients with locally advanced cervix cancer enables smaller target volumes to be used, with the main expectation that this should translate into less toxicity for the patient. A Plan of the Day (POTD) approach uses a number of plans modeling target position with variable bladder filling.

The purpose of this work was to: 1. Establish a workflow, 2. Develop and deliver a radiographer training program for plan selection, 3. Evaluate the resources required to implement ART with POTD as standard of care.

Material/Methods:

Institutional approval was granted to set up a multidisciplinary working group to establish the treatment workflow and therapeutic radiographer (RTT) training to implement POTD as standard of care. The following steps were addressed and resources required to implement were evaluated;

1. Treatment protocol.

2. Patient selection.

3. Radiotherapy treatment planning (RTP).

4. Target localisation.

5. Planning target volumes.

6. Physics planning protocol and checking.

7. Radiographer competency.

8. Plan selection pathway (see figure 1).

9. Treatment verification.
