Abstract

fetched live from OpenAlex

AIMS: To compare the treatment efficacy and radiation complications between (125)Iodine brachytherapy and stereotactic radiotherapy in the management of juxtapapillary choroidal melanoma. METHODS: Consecutive juxtapapillary melanoma patients treated with radiotherapy were included. Patients were divided into two cohorts: patients treated with (125)Iodine brachytherapy and patients with stereotactic radiotherapy. Comparison included the rates postradiotherapy local recurrence, secondary enucleation, metastasis and radiotherapy complications. Kaplan-Meier estimates were used to determine the actuarial rates, and logrank test to compare between the estimates. RESULTS: We included 94 patients with juxtapapillary melanoma treated with radiotherapy. The brachytherapy cohort included 30 patients and stereotactic radiotherapy was 64. The median follow-up was 46 months in both cohorts. No statistically significant differences existed between the two cohorts on comparing pretreatment clinical data and tumour characteristics. On comparing treatment efficacy, the actuarial rates at 50 months for tumour recurrence were 11% and 7% (p=0.61), secondary enucleation was 11% and 21% (p=0.30) and for metastasis were 4% and 16% (p=0.11), respectively. On comparing treatment complications, the actuarial rates at 50 months for cataracts were 62% and 75% (p=0.1), for neovascular glaucoma 8% and 47% (p=0.002), for radiation retinopathy 59% and 89% (p=0.0001), and for radiation papillopathy 39% and 74% (p=0.003), respectively. CONCLUSIONS: Both (125)Iodine brachytherapy and stereotactic radiotherapy demonstrate comparable efficacy in the management of juxtapapillary choroidal melanoma. However, stereotactic radiotherapy shows statistically significant higher radiation-induced ocular morbidities at 4 years postradiotherapy.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
