Dose Escalation Study at NIRS
For the purpose of finding an appropriate dose level, dose escalation
studies have been performed at NIRS.
Radiation dose was escalated
by increasing the fraction size, while
keeping both the fraction number and the length of treatment
constant
.
The treatment was delivered
4 days a week
and the radiation dose
was increased
in increments of 5 to 10%
up to the dose level at
which tolerance might be reached.
In recent years, the average number of treatment fractions per
patient has been around
13
and the average treatment period
about
3 weeks
.
