Remote afterloading high dose rate radionuclide skin surface brachytherapy, includes basic dosimetry, when performed; lesion diameter up to 2.0 cm or 1 channel

Remote afterloading high dose rate (HDR) radionuclide skin surface brachytherapy is a specialized treatment method used primarily for non-melanoma skin cancers. This procedure utilizes a high dose rate of radioactive material delivered directly to the skin surface, allowing for targeted treatment of cancerous lesions while minimizing damage to surrounding healthy tissue. The term "remote afterloading" refers to the technique where the radioactive source is loaded into the applicators after they have been placed in the patient, ensuring that the healthcare provider is not exposed to radiation during the procedure. The procedure is designed to treat lesions with a diameter of up to 2.0 cm or through a single channel, making it a precise and effective option for managing localized skin cancers. The process begins with careful planning, including the selection of an appropriate surface applicator based on the lesion's depth and size, followed by meticulous placement and monitoring throughout the treatment. This method not only reduces the need for surgical intervention but also shortens the overall duration of radiation exposure required for effective treatment.
