Snare technique for enucleation of eyes with advanced retinoblastoma.
Retrospective analysis of surgical outcomes for enucleation in pediatric retinoblastoma stage 5B using the snare wire loop (n = 55) and standard curved enucleation scissors (n = 22) revealed that a statistically significant longer mean optic nerve length was obtained with the snare (13.35 mm) compared with scissors (11.05 mm; P = .005). Four scissor cases had prolonged bleeding and required thr...
متن کاملThree histopathological types of retinoblastoma and their relation to heredity and age of enucleation.
The histopathology of 61 eyes was studied with special attention to the morphology of the retina adjacent to the main tumour. Three retinal types were distinguished. Retina type 1 (RT-1, 28 specimens) contained a single tumour that was sharply demarcated from surrounding normal retina. In retina type 2 (RT-2, 29 specimens) large parts of the retina were affected and the main tumour mass gradual...
متن کاملHistopathological features and P-glycoprotein expression in retinoblastoma.
PURPOSE To investigate the expression of P-glycoprotein (P-gp) in retinoblastoma specimens enucleated as a primary treatment or after conservative treatment and to correlate this expression with histopathological tumor features. METHODS Retrospective analysis was performed on retinoblastoma specimens obtained consecutively between 1993 and 2003 by enucleation either as primary treatment (grou...
متن کاملSirtuin1 Expression and Correlation with Histopathological Features in Retinoblastoma
Background: Sirtuin1 (Sirt1) is a member of highly conserved proteins and has been implicated as a tumor promoter as well as a tumor suppressor. One of the mechanisms involves deacetylation of retinoblastoma protein, thereby inhibiting the tumor suppressor function. No study has been reported on the expression of Sirt1 in retinoblastoma. Methods: We assessed the expression of Sirt1 in sections ...
