Variability in Radiation Oncologists' Opinion on the Indication of a Bolus in Post-mastectomy Radiotherapy: an International Survey

There is a wide variation in the use of a bolus in PMRT with significant regional differences. This probably translates into a variation in the dose delivered to the skin and may have an effect on local recurrence and/or toxicity. A randomised clinical trial is needed to evaluate the benefit and toxicity associated with the use of a bolus in PMRT.
