چکیده مقاله:
Background: We aimed to achieve full tumor control during every fraction with head and neck cancer patients using ۳DCRT treatment technique. Method: We divided ۱۶ head and neck cancer patients into two groups to deliver radiotherapy doses of ۶۶Gy and intensity modulated radiotherapy (IMRT) ۷۰Gy. We applied ۳DCRT plan as a forward IMRT plan for each patient with coplanar beams arrangement technique designed with angles of (۰o, ۶۰o, ۹۰o, ۱۸۰o (or around ۱۷۵o and ۱۸۵o), ۲۷۰o and ۳۰۰o).We assessed the plans according to DVHs and satisfactory dose distributions. Results: Based on the overall evaluation of the two groups (۱۶ 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 ۷۰Gy, while sparing critical organs. This template could be used in countries with no access to forward IMRT planning.
