High-resolution, ultrasound-guided, high-dose-rate, surface brachytherapy for basal cell carcinoma of the skin: A case report

摘要

Nonmelanomatous skin cancer (NMSC) is the mostcommon type of malignancy, and radiation therapy (RT)is an excellent alternative treatment for patients who aremedically inoperable or refuse surgery.1,2 High-dose-rate(HDR) surface brachytherapy (BT) can spare adjacentand deeper normal tissue from radiation doses whiledelivering a larger radiation dose to skin cancers.3,4Therefore, surface BT is especially suitable for patientswho have lesions that are located in sensitive anatomicregions such as the scalp, eyes, or nose.3,4 Ultrasoundguidance is needed typically for tumor localization duringBT for prostate and cervical cancers, but its use forNMSC treatment is uncommon.5,6 Here, we report on thefirst case, to our knowledge, in which 3-dimensional,high-resolution ultrasound guidance is used duringiridium-based BT for NMSC.
