ABSTRACT
El Retinoblastoma es la neoplasia ocular más frecuente en pediatría. La Terapia radiante externa fue hasta hace una década el tratamiento conservador de elección. Luego se incluyó la quimio reducción; en un intento de evitar la radioterapia externa y sus complicaciones. En este estudio retrospectivo evaluamos los resultados del tratamiento conservador con terapia radiante externa o con quimio reducción en el servicio de oftalmología del Hospital Nacional de Pediatría Juan P. Garrahan, desde 1987 a 2009. De un total de 571 pacientes con diagnóstico de Retinoblastoma, 341 fueron unilaterales y 217 bilaterales. De estos últimos se analizaron 166 pacientes cuya edad media al diagnostico fue de 12 meses. Se trataron 332 ojos de 166 pacientes con Retinoblastoma bilateral, 157 ojos (47,3%) recibieron quimioreducción como tratamiento inicial, 115 ojos (34,6%) fueron enucleados al inicio, 45 ojos (13,6%) recibieron radioterapia externa como único tratamiento y 15 ojos (4,5%) recibieron tratamiento local solo (laser o crioterapia) como primera elección. Se analizaron los datos con el programa estadístico STATA 12.0 stataCorp Texas.USA. La agudeza visual final fue superior a 20/70 en el 51,5% de los pacientes e inferior en el 48,5%. Se encontró una relación significativa (p=0,005) entre el estadio al diagnóstico y la agudeza visual final; los pacientes con discapacidad visual se presentaron con estadios avanzados. Se evaluaron todas las orbitas enucleadas (157); de ellas el 74,5% recibieron radioterapia externa antes o después de la enucleación. El 24,8% de las orbitas irradiadas presentaron deformidad de la cavidad, con mala adaptación de prótesis y retracción orbitaria, el 70,1% presentaron cambios que permitían una adaptación de prótesis aceptable con alguna limitación de movilidad y solo 6 orbitas (5,12%) presentaban una muy buena cavidad para adaptación cosmética. Cuarenta de 157 orbitas enucleadas no recibieron radioterapia en ningún momento (25,5%), el 92,5% de ellas presentaron buena adaptación y solo el 7,5% tuvieron problemas de adaptación debido a complicaciones postoperatorias. El diagnóstico precoz, el tratamiento oportuno, y el uso de quimio reducción como terapia inicial en Retinoblastoma intraocular, permiten aumentar la tasa de preservación del globo ocular y reducen o eliminan la necesidad de recibir Terapia radiante externa, evitando sus secuelas (AU)
Retinoblastoma is the most common ocular neoplasia in childhood. External beam radiation therapy was the conservative treatment of choice until a decade ago. Subsequently, chemoreduction was added trying to avoid external beam radiation therapy and its complications. In this retrospective study we assess the results of conservative therapy with external beam radiation therapy or with chemoreduction at the Department of Ophthalmology at the Pediatric Hospital Juan P. Garrahan between 1987 and 2009. Of a total of 571 patients with a diagnosis of retinoblastoma, 341 had unilateral and 217 bilateral retinoblastoma. Of the latter patients, 166 patients were analyzed with a mean age at diagnosis of 12 months. Overall, 332 eyes of 166 patients with bilateral retinoblastoma were treated; at initial treatment 157 eyes (47.3%) underwent chemoreduction, 115 eyes (34.6%) were enucleated, 45 eyes (13.6%) underwent external beam radiation therapy as the only treatment, and 15 eyes (4.5%) only received local treatment (laser or cryotherapy) as a first choice. Data were analyzed using STATA 12.0 stataCorp Texas.USA. Final visual acuity was more than 20/70 in 51.5% and less in 48.5% of the patients. A significant relationship (p=0.005) between stage at diagnosis and final visual acuity was found; patients with visual impairment presented with advanced stages. All enucleated orbits were assessed (157); 74.5% underwent external beam therapy before or after enucleation. Of all irradiated orbits, 24.8% presented with cavity deformity, poor prosthesis fit, or contraction of the socket. Of all patients, 70.1% presented with changes that allowed acceptable fitting of the prosthesis with slight movement limitation and only 6 orbits (5.12%) had a good cavity for cosmetic appearance. Forty of 157 enucleated orbits did not receive radiation therapy at any moment (25.5%); 92.5% of them had a good fitting and in only 7.5% fitting problems due to postoperative complications were found. Early diagnosis, adequate treatment, and use of chemoreduction as initial therapy of intraocular retinoblastoma allow for an increased rate of preservation of the eye and reduce or eliminate the need for external beam therapy and its sequelae (AU)

A 3-year-old girl presented with left exotropia. Funduscopy demonstrated a retinocytoma associated with five discrete retinoblastomas in the left eye and three discrete retinoblastomas in her right eye. The clinical manifestations and fundus imaging findings are described.

PURPOSE: The authors aimed to analyze the long-term effects of treatments, especially external beam radiotherapy (EBRT), in bilateral retinoblastoma patients. METHODS: This retrospective study analyzed the medical records of 22 bilateral retinoblastoma patients who were registered between October, 1987 and October, 1998 and followed-up for more than 10 years. They were treated by enucleation, EBRT, and systemic chemotherapy. Age at diagnosis, sex, delay prior to treatment, Reese-Ellsworth (RE) classification, and the local treatment modalities were analyzed in relation to recurrence-free survival (RFS) and complications. RESULTS: Median age at diagnosis was 7.0 months (range 1.7-31.6 months). Leukocoria was the most common presenting feature. Two patients had a familial history. The RE classifications of the 44 eyes were group II in 4, III in 14, IV in 4, and V in 22. At the end of a median follow-up period of 141 months (range 55-218 months), 20 patients were alive. The 10-year ocular survival rate of the 44 eyes was 56.8+/-7.5%. The 10-year RFS and ocular survival rate of the 29 eyes treated by combined EBRT and chemotherapy were 75.9% and 86.2%, respectively. Treatment delay (>3 months) was found to be related to higher risk of recurrence. Complications after EBRT were cataract, retinal detachment, phthisis bulbi, and facial asymmetry. No patient developed a second malignancy during the follow-up period. CONCLUSION: Early detection and prompt treatment can increase ocular survival rates. In addition, careful attention should be paid to possible long-term sequelae in these patients.

PURPOSE: To investigate the courses leading to bilateral enucleation in bilateral retinoblastoma patients. METHODS: Medical records of 5 bilateral retinoblastoma patients who underwent bilateral enucleation were reviewed for patient information, history, change of tumor state during the treatment and the cause of bilateral enucleation. RESULTS: Out of 48 bilateral retinoblastoma patients, both eyes were saved in 6 children, 1 eye was saved in 37 children, and the remaining 5 children lost both eyes. All patients who underwent bilateral enucleation were female and had no family history of retinoblastoma. At diagnosis, 3 children were 4 months old and the remaining 2 patients were 1 year and 1.5 years old each. Out of 10 eyes, 8 eyes were in Reese Ellsworth group V and the remaining 2 eyes were in group III. The initial treatment was enucleation of 1 eye followed by chemotherapy in 3 patients, and chemotherapy alone in 2 patients. Additional treatment included laser photocoagulation, cryotherapy, external beam radiation therapy and proton beam irradiation. Vitreous seeding, development of new tumors, and increase in tumor size despite of intensive, conservative treatment resulted in second enucleation. CONSLUSION: Most patients who underwent bilateral enucleation were 1 year old or younger at diagnosis of retinoblastoma. All patients had a progressed disease status at presentation and showed poor response to intensive, conservative treatment.
