One poor cosmetic result (0.5%) was reported, and 77.5% of lesions experienced excellent cosmetic results.ĭisclosure: For full disclosures of the study authors, visit . Between 19, 166 patients with T1 or T2 epidermoid carcinomas of the mobile tongue were treated by iridium 192 implantation (70 T1N0, 83 T2N0, 13 T1-2 N1-3). Dermatitis (22.0%) and pain (8.2%) occurred as acute grade 1 or 2 toxicities. Iridium-192 is a radioactive isotope, meaning its a version of iridium with a different number of neutrons than is contained in the dominant forms of the element. The most commonly occurring late toxicities were grade 1 hypopigmentation (27.5%) and fibrosis (8.2%) and grade 2 ulceration (0.5%). For example, if on August 23, the activity of Ir 192 is taken at 100 Ci, the calculation to determine the activity.

Lesions underwent treatment of 40 Gy in 8 fractions two to three times weekly using Valencia applicators with a diameter of either 20 mm (n = 105 57.7%) or 30 mm (n = 77 42.3%).Īt a median follow-up of 14 months, the 2-year local control rate was 96%. All reviewed lesions were a maximum of 25 mm in diameter and 4 mm in depth. Represented cancers included basal cell carcinoma (61.5%) and squamous cell carcinoma (38.5%).

The retrospective study analyzed data from 95 patients with non-melanoma skin cancer who received iridium-192 high-dose–rate brachytherapy using Valencia applicators between June 2015 and December 2020 at the University of Pisa. Iridium PTT is built for security, with no-compromise AES-256 encryption standards to deliver instant, secure group communications. Fabiola Paiar, MD, PhD, of the University of Pisa in Italy, and colleagues determined that the treatment may be an alternative for elderly patients who may not be candidates for surgery. Iridium delivers reliable, low-latency, weather-resilient L-band connectivity to enable rapid response times for all your mission-critical communications.
