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.
