A Feasibility Study of IMRT Modulation to Account for Scattered Radiation From Dental Fillings in Head and Neck Cancer Patients
The main objective of this study is to determine the feasibility of optimizing the IMRT
treatment plan based on dosimeter measurements of mucosal radiation dose adjacent to the
dental fillings to reduce such dose to < 35 Gy without compromising tumor coverage and/or
increasing the dose to the remaining oral cavity or nearby parotid glands.
treatment plan based on dosimeter measurements of mucosal radiation dose adjacent to the
dental fillings to reduce such dose to < 35 Gy without compromising tumor coverage and/or
increasing the dose to the remaining oral cavity or nearby parotid glands.
Inclusion Criteria:
- Patients with HNC undergoing radiation therapy +/- chemotherapy at Stanford
University
- Age >= 18 years old
- Metallic filling present
- Planned radiation dose to the tumor > 60 Gy at 1.8-2.2 Gy/fx
- Able to understand and sign a written informed consent document.
Exclusion Criteria:
- Patients who are pregnant or nursing, which preclude them from undergoing active
radiation treatment.
