Abstract

Purpose/Objective: At the Danish wards for radiotherapy
there are different rules regarding the intervals that have to
pass from the moment the patients applies moisturizer until
they can be treated. This is due to the fact that it is unclear
whether the cream can cause bolus effect, thereby causing
the dose to move towards the skin. This would increase the
damages to the patient’s skin during the radiotherapy. There
is no evidence on the use of moisturizers.
Materials and Methods: We have carried out an experimental
trial testing whether creams cause bolus effect. We used two
pieces of pork which we each divided into three squares in
order to test our three preparations: Decubal Original Clinic
Cream, Panthenol cream and Panthetonol ointment. All scans
were carried out using a 64 slice Philips Brilliance Big Bore CT
scanner.
Conclusions: According to our results of the ml.
measurements we can conclude: Panthenol ointment is the
preparation which causes the smallest bolus effect.
According to our results of the time measurements we can
conclude: After four hours all the preparations in question
still cause bolus effect. Because the bolus effect occurs even
by very small quantities of cream and as it does not
disappear within four hours, the patients should postpone the
application until the therapy is over, whereby the additional
bolus effect can be completely avoided.
