Bolus in Radiation Therapy: The Versatility of Water.

Miescke, Amara

Background Bolus material is commonly used in radiation therapy to bring the radiation dose closer to the skin surface to treat superficial lesions. Many types of bolus can be used, each possessing advantages and disadvantages. Discussion The literature review detailed 2 common types of bolus materials: water and Superflab. Analysis of 3 case studies revealed that in each case, the patient setup was unique and required creative bolus design. Water was found to be a versatile bolus option for all 3 cases. Conclusion Using the correct type of bolus when treating a superficial lesion with radiation prevents underdosing the tumor and overdosing healthy structures. Radiation therapists should be aware of the types and uses of bolus to assess patients accurately and determine the most appropriate bolus material for treatment.
