Retinoblastoma in Jordan, 2003-2013: Ocular survival and associated factors

AbstractPurpose: To determine ocular survival and factors affecting globe survival in patients diagnosed with retinoblastoma at King Hussein Cancer Center (KHCC).Methods: A retrospective review of medical records of 71 Jordanian patients (45 males and 26 females) diagnosed with retinoblastoma (114 eyes) between June 2003 and May 2013 was conducted. Patient sociodemographic and relevant characteristics were collected from records. Patients with bilateral retinoblastoma were treated with chemoreduction and focal consolidation. Lens-sparing radiation therapy and enucleation were reserved for eyes that failed chemoreduction combined with focal therapy. In cases of unilateral retinoblastoma, primary enucleation was recommended for eyes with advanced unilateral disease (Reese-Ellsworth classification groups IV and V). Kaplan-Meier survival and Cox regression multilevel analysis were used to analyze the data.Results: Median age at diagnosis was 12 months. The follow-up period ranged from 0.25–160 months (mean 26...
