Introduction: For many years, the gold standard in the localization of non-palpable malignant breast tumors has been the use of wire-guided method. However, this has recently been replaced by more modern localization techniques in many institutions.
Methods: This is a retrospective case-control study comparing two localization techniques (iodine seed 125I and wire-guided localization) for localizing non-palpable tumors in patients with histologically verified breast carcinoma.
Results: The study included 62 patients - 31 with localization of malignant breast tumor by iodine seed (subgroup 125I) and 31 by wire-guided localization (subgroup FV). The average volume of the resected tissue in subgroup 125I (46.2 cm3) was statistically significantly smaller compared to subgroup FV (83.7 cm3; P = 0.0063). R0 resection was achieved in 29 cases (93.5%) in subgroup 125I and in 24 cases (77.4%) in subgroup FV (P = 0.0714). In subgroup 125I, re-resection was not indicated in any case, while in subgroup FV, re-resection due to tumor reaching the margin was indicated in 6 cases (19.4%; P = 0.01).
Conclusion: Our initial experience show that the use of iodine seeds for localizing non-palpable breast tumors is associated with the removal of a smaller volume of resected tissue compared to wire-guided localization, with a trend towards more frequent achievement of R0 resection. In the subgroup of patients localized with iodine seeds, there was a smaller proportion of re-resections due to inadequate safety margins.

Intraocular Tumors Unit, Valladolid University Hospital, Valladolid, Spain.
Purpose: The aim of this study was to analyze the course of visual acuity (VA) in visual outcomes of patients treated with iodine-125 (I) brachytherapy in our center, based on original VA before treatment.
Material And Methods: Visual acuity was prospectively assessed using a case series of 305 patients treated with I between 1996 and 2022. To examine how VA behaves over time, we divided patient sample into 4 groups: (1) Patients with visual acuity of less than V ≤ 0.

Background: Currently, it is unknown whether iodine-125 (I) stent implantation has the same therapeutic effect on patients with malignant biliary obstruction (MBO) caused by different cancers. This meta-analysis aimed to investigate whether I implantation in patients with MBO is superior to biliary stent placement in efficacy and safety, and to further explore the difference in efficacy and safety of seed implantation in different patients through subgroup analysis.
Methods: A systematic search of the PubMed, Wiley Online Library, Cochrane library, Google Scholar, the Web of Science, China National Knowledge Infrastructure (CNKI), VIP, and Wanfang databases was conducted to screen all relevant studies up to October 30, 2022.

Purpose: Radioguided localization can assist the surgery of hard-to-find lesions. The aim was to evaluate the results of the I Radioactive Seed Localization (RSL) technique to guide a margin-free tumoral resection of mesenchymal tumours compared to conventional surgery and its influence in oncological outcomes.
Methods: Retrospective observational study of all consecutive patients who underwent I RSL for the surgery of a mesenchymal tumour from January 2012 to January 2020 in a tertiary referral centre in Spain.

Background: One of the challenges in living kidney donor screening is to estimate remaining kidney function after donation. Here we developed a new model to predict post-donation measured glomerular filtration rate (mGFR) from pre-donation serum creatinine, age and sex.
Methods: In the prospective development cohort (TransplantLines, n = 511), several prediction models were constructed and tested for accuracy, precision and predictive capacity for short- and long-term post-donation 125I-iothalamate mGFR.
