Retinoblastoma, although a rare childhood cancer, is the most common primary malignant intraocular tumor of infancy and early childhood. In 75% of the cases, retinoblastoma is unilateral, and in 25% of the cases, retinoblastoma is bilateral. Presenting signs and symptoms of retinoblastoma, genetics, diagnostic tests, and their implications are reviewed

Journal of Pediatric Ophthalmology & Strabismus, 1987
ABSTRACT Retinoblastoma was diagnosed in 74 patients between July 1967 and February 1987. Thirty cases (40%) were bilateral; 39 were female and 35 were male. Treatment in bilateral cases consisted of enucleation of the more involved eye and a combined approach of supervoltage irradiation, cryocoagulation, and photocoagulation to the remaining

Retinoblastoma is the most common ocular malignancy of childhood. With an estimated 300 cases annually in the United States, retinoblastoma is nevertheless considered a rare tumor. Although retinoblastoma primarily affects younger children, diagnosis during the neonatal age range is less common. However, an understanding of patients at risk is critical

Retinoblastoma (Rb) is a malignant tumor that originates from developing retina. Diagnosis based on clinical signs and symptoms and is usually made in children under the age of five years. Mutations in both alleles of the RB1 gene are a prerequisite for this tumor to develop.

Bilateral retinoblastoma with ectopic intracranial retinoblastoma: Trilateral retinoblastoma
Cancer Genetics and Cytogenetics, 1982In 11 patients, bilateral retinoblastoma presented at a mean age of 6 months and pineoblastoma at 4 years. We suggest that the hereditary multicentric retinoblastoma arose in vestigeal photoreceptors in the pineal as well as in the hypothetical retinoblasts of the retina.

Retinoblastomas are the most frequent intraocular tumors in childhood. Untreated, the tumor is almost always fatal. Using a multidisciplinary approach combining the efforts of ophthalmologists, radiation oncologists, pediatric oncologists and geneticists a survival rate of more than 95% can be achieved.

Trilateral retinoblastoma: ocular and pineal retinoblastomas
Journal of Neurosurgery, 1985✓ Trilateral retinoblastomas, the syndrome of bilateral retinoblastoma associated with ectopic retinoblastoma in the pineal gland, is rare but well recognized. In contrast to bilateral retinoblastomas alone, the ocular retinoblastomas in trilateral retinoblastoma develop before the age of 6 months, and a family history positive for retinoblastoma is ...

Chemotherapy for Retinoblastoma
Ophthalmic Paediatrics and Genetics, 1989Fourteen patients with retinoblastoma treated with chemotherapy in our hospital were surveyed to study the effects of chemotherapy on retinoblastoma. These patients were compared with those registered in 1980 and 1981 in Japan. In unilateral retinoblastoma limited to the eyeball, there was no significant difference in outcome between the chemotherapy ...

Human Genetics, 1979
The genetic basis of retinoblastoma is reviewed and the following conclusions are drawn: 1) The mode of inheritance of the hereditary variety of retinoblastoma (R) is autosomal dominant with about 90% penetrance. 2) About 68% of inherited cases are bilateral, and about 32%, unilateral.

Cryotherapy for Retinoblastoma
Archives of Ophthalmology, 1982Cryotherapy was applied to 138 intraocular retinoblastoma tumors from 113 patients who were followed up for a mean of 40 months (four to 144 months). Overall, 70% of tumors were cured with cryotherapy and 93% of patients treated with cryotherapy survived.
