Purpose: A 2-year-old boy with syndromic bilateral retinoblastoma resulting from a (del(13)(q12.3q14.3)) developed a recurrent tumor measuring 2.3X2.3mm at the ora serrata 15 months following last treatment. Methods: Ultrasound biomicroscopy (UBM) revealed a mass invading the ciliary body 6.6 mm in diameter associated with a localized supraciliary effusion. Results: Complete tumor regression was achieved 1 month after brachytherapy with a (106)Ruthenium plaque. There was no recurrence at 16 months. Conclusion: This is the first clinical demonstration of supraciliary effusion in recurrent retinoblastoma. Brachytherapy appears to be effective in the treatment of this type of recurrence.

To identify predictors of treatment response by evaluating long-term outcomes of vasoproliferative retinal tumors after ruthenium-106 brachytherapy.
We have retrospectively analyzed the outcomes of high-dose-rate (HDR) brachytherapy as a salvage therapy for vaginal recurrence of endometrial cancer.
We aimed to evaluate the impact of timing of androgen deprivation therapy (ADT) on survival in a cohort of patients with biochemical recurrence (BCR) after brachytherapy treatment for prostate cancer.
The purpose of this work is to present a brief review of MRI physics principles pertinent to prostate brachytherapy, and a summary of our experience in optimizing protocols for prostate brachytherapy ...
Retinoblastoma is the most common primary intraocular malignancy in children. The management of retinoblastoma is complex and depends on several factors.
RATIONALE: Drugs used in chemotherapy, such as carboplatin and vincristine, work in different ways to stop tumor tumor from dividing so they stop growing or die. It is not yet known whethe...
MRI is useful for diagnosing pinealoblastoma in retinoblastoma patients
The purpose of the research study is to learn more about the causes of retinoblastoma and to identify possible risk factors in the parents of patients with retinoblastoma. This kind of stu...
The purpose of this study is to find out about the quality of life and health in a group of adults who had retinoblastoma when they were children. By quality of life, we mean how you are f...
1. Assessment of a high speed video camera with a green light source for the measurement of ciliary beat frequency (CBF) in the nasal airways of patients. 2. Assessments of the eff...
Unstable isotopes of ruthenium that decay or disintegrate emitting radiation. Ru atoms with atomic weights 93-95, 97, 103, and 105-108 are radioactive ruthenium isotopes.
Inorganic compounds that contain ruthenium as an integral part of the molecule.
An inorganic dye used in microscopy for differential staining and as a diagnostic reagent. In research this compound is used to study changes in cytoplasmic concentrations of calcium. Ruthenium red inhibits calcium transport through membrane channels.
Product of the retinoblastoma tumor suppressor gene. It is a nuclear phosphoprotein hypothesized to normally act as an inhibitor of cell proliferation. Rb protein is absent in retinoblastoma cell lines. It also has been shown to form complexes with the adenovirus E1A protein, the SV40 T antigen, and the human papilloma virus E7 protein.
A ubiquitously expressed regulatory protein that contains a retinoblastoma protein binding domain and an AT-rich interactive domain. The protein may play a role in recruiting HISTONE DEACETYLASES to the site of RETINOBLASTOMA PROTEIN-containing transcriptional repressor complexes.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
