Purpose: To assess the effectiveness of I-125 seeds (IS) insertion with transcatheter arterial chemoembolization (TACE) in treating patients with advanced hepatocellular carcinoma (HCC).
Material And Methods: An extensive search was conducted for relevant randomized controlled trials (RCTs) from the establishment date of each database to November 2020.
Results: A total of nine RCTs were included in this study. Our analysis showed no significant changes in the pooled Δalpha-fetoprotein values = .06, incident rates of myelosuppression ( = .46), vomit occurrence ( = .27), and abnormal liver function ( = .42) between the two treatment groups. However, the complete response ( < .00001), total response ( < .00001), and disease control ( < .00001) rates were significantly higher in patients who underwent TACE with IS insertion, as opposed to patients who received TACE alone. Furthermore, patients who underwent TACE with IS insertion experienced markedly longer pooled overall survival (OS) time ( < .0001), with better OS rates at the six-month ( = .0002), one-year ( < .0001), and three-year ( = .0003) follow-ups than patients who received TACE alone.
Conclusion: TACE with IS insertion can significantly improve clinical response and prolong the survival of advanced HCC patients.

Background: Patients with advanced cholangiocarcinoma (CCA) often experience malignant obstructive jaundice (MOJ), which significantly impacts both their quality of life and prognosis. Recent studies suggest that the addition of iodine-125 (125I) radioactive seeds during stent placement may improve stent patency and extend patient survival. However, the conclusions drawn from different studies remain inconsistent, and there is a lack of a systematic assessment to better clarify the clinical benefits of this treatment.

Objective: To develop and validate a practical method for accurate dose calculations of low-dose-rate brachytherapy treatment of eye tumors.
Methods: Dose calculations of 16 mm Collaborative Ocular Melanoma Study (COMS) and 20 mm notched eye plaques with I seeds were performed using the egs_brachy package of the EGSnrc Monte Carlo (MC). Several eye phantoms were modeled, including: (1) uniform phantoms made of only tumor (T), water, or vitreous body (VB) medium; (2) scaled water (SW) and scaled VB (SVB) distributions were derived by scaling the precomputed distributions for all-water and all-vitreous geometries by the relative energy absorption coefficient or each ocular structure to that of water or the vitreous body, respectively; (3) fully defined eye phantom with all structural materials defined; and 4) TG-43 calculations.

Purpose: This study assessed the effectiveness and prognostic factors of CT-guided ¹²⁵I seed implantation for primary hepatocellular carcinoma (HCC).
Methods: A retrospective analysis of 71 patients (57 males, 14 females, median age 64) treated at three Chinese hospitals from 2018 to 2024 was conducted. The main outcomes were local progression-free survival (LPFS) and overall survival (OS).

Background: Hemoptysis is a critical complication in advanced lung squamous cell carcinoma (LUSC). This study aims to evaluate the effectiveness and safety of 8Spheres microspheres embolization combined with iodine-125 seed implantation for managing hemoptysis in patients with advanced LUSC.
Methods: A retrospective analysis was performed involving 45 patients diagnosed with advanced squamous cell carcinoma and experiencing hemoptysis.

This study aimed to investigate the effect of tissue calcification on the dose distribution of low-energy brachytherapy seeds used in the treatment of prostate and breast tumors. To achieve this, simulations of the IR-I andCs-1 seeds were conducted using the MCNPX Monte Carlo (MC) code. Brachytherapy dosimetric parameters, such as the dose rate constant (Λ) and radial dose function (g (r)), were calculated in water following the TG-43U1 protocol and validated by comparing the results with data reported in other literature.
