“…The face is a difficult area for a bolus to adhere to the skin because of its irregular contours. Therefore, several bolus studies have been published [8,9,12,13]. For instance, Park et al reported that a bolus could be fabricated using a three-dimensional (3D) printer [14].…”

Radiation therapy with X-rays for skin cancer uses a bolus to increase the surface dose. Commercial gel sheet boluses adhere poorly to the patient’s body because of surface irregularities. This causes an air gap and reduces the surface dose. We have developed a novel shapeable bolus (HM bolus; Hayakawa Rubber Co., Ltd., Hiroshima, Japan), and we describe the first clinical application of this bolus here. The case was an 82-year-old male with a facial cutaneous squamous cell carcinoma. The postoperative radiotherapy plan using the HM bolus provided a more uniform dose to the target compared with a plan without the HM bolus. The HM bolus adhered stably to the patient’s skin, and there were no issues with its clinical use.
