Abstract
INTRODUCTION: Iodine-125 (I-125) seeds, commonly used in low-dose rate brachytherapy for ocular malignancies, are often discarded after a single use. This study examines the potential cost savings at an institution with high ocular melanoma referrals, by re-using I-125 seeds for eye-plaque brachytherapy.
METHODS: In this single-institutional retrospective analysis, data was collected from I-125 seed orders from 8/2019 through 10/2022. Information including number of seeds ordered per lot, number of plaques built per lot, and number of seeds used per lot were collected. Cost per lot of seed was assumed to be the current cost from the most recent lot of 35 seeds.
RESULTS: During the study, 72 I-125 seed lots were ordered bi-weekly, with a median of 35 seeds per lot (Range: 15-35). Each seed was used on average 2.26 times prior to being discarded. The average duration of each seed lot used was 62.2 days (Range: 21-126). Each seed lot contributed to the construction of an average of 8.4 eye plaques (Range: 2-20). With seed recycling, 2,475 seeds were used to construct 608 eye-plaques. Without re-using practice this would require 5,694 seeds. This resulted in a percentage cost savings of 56.5%, with a total seed cost reduction of $344,884, or $559 per eye-plaque on average.
CONCLUSION: This is the first study to evaluate cost savings relative to re-using I-125 seeds for eye plaques. The data demonstrates how an institution can decrease costs associated with I-125 radiation seeds used for eye-plaque brachytherapy by re-using them.
