Abstract

Background: We aimed to achieve full tumor control during every fraction with head and neck cancer patients using 3DCRT treatment technique. Method: We divided 16 head and neck cancer patients into two groups to deliver radiotherapy doses of 66Gy and intensity modulated radiotherapy (IMRT) 70Gy. We applied 3DCRT plan as a forward IMRT plan for each patient with coplanar beams arrangement technique designed with angles of (0o, 60o, 90o, 180o (or around 175o and 185o), 270o and 300o).We assessed the plans according to DVHs and satisfactory dose distributions. Results: Based on the overall evaluation of the two groups (16 cases), we achieved an accepted dose distribution for PTVs and OARs dose; simulating IMRT inverse plans dose distribution. Conclusion: Using such a mono-isocenteric plan, we were able to achieve a perfect uniform dose distribution for PTVs up to 70Gy, while sparing critical organs. This template could be used in countries with no access to forward IMRT planning.
