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.

Name: Ophthalmic genetics
To evaluate the incidences of vaginal recurrence and toxicity after vaginal brachytherapy in Stage I-II endometrial cancer.
Ophthalmic artery chemosurgery (OAC) has emerged as a primary treatment for advanced-stage retinoblastoma. To our knowledge, the incidence of orbital recurrence in eyes treated with OAC has not been d...
Various treatment options exist for nonmelanoma skin cancer (NMSC), including topical agents, surgery, or definitive or adjuvant radiation therapy. Recently, electronic surface brachytherapy (ESB) has...
Primary cilia interpret vertebrate Hedgehog (Hh) signals. Why cilia are essential for signaling is unclear. One possibility is that some forms of signaling require a distinct membrane lipid compositio...
To evaluate the clinical outcome of a cohort of localized prostate cancer patients treated with 125-I permanent brachytherapy at the São José Hospital - CHLC, Lisbon.
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...
The purpose of this study is to show that chemotherapy delivered directly through the artery supplying the eye (ophthalmic artery) to patients with retinoblastoma is a safe and effective t...
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...
