Remote afterloading high dose rate radionuclide skin surface brachytherapy, includes basic dosimetry, when performed; lesion diameter over 2.0 cm and 2 or more channels, or multiple lesions

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 on or near the tumor, ensuring that the medical staff can maintain a safe distance during the radiation exposure. The procedure is particularly beneficial for lesions that are larger than 2.0 cm in diameter or when multiple lesions are present, as it allows for effective treatment without the need for surgical intervention. The process begins with careful planning, including the selection of appropriate surface applicators based on the depth and size of the lesions, followed by meticulous placement and adjustment of these applicators to ensure optimal delivery of radiation. The use of a remote afterloading machine further enhances safety and precision, as it automates the loading of the radioactive source into the applicators while the patient is monitored closely. This method not only shortens the duration of radiation treatment but also improves patient comfort and outcomes.
