| Abstrakt: | Purpose: To examine the profile of retinoblastoma in a national tertiary referral center in Tanzania and to report first-year outcomes of its treatment using chemotherapy. Methods: All patients with retinoblastoma referred in 2008 were included. Disease was classified on clinical grounds as ocular, orbital, or metastatic. Those with ocular and orbital disease received chemotherapy. Remission was the main outcome measure and defined as absence of disease at the end of treatment. Results: In 2008, 37 patients (20 males and 17 females) with retinoblastoma were referred to Ocean Road Cancer Institute. The mean delay from the first sign of disease to presentation at hospital was 10.4 ± 8.7 months. Disease was ocular in 32% (12 of 37), orbital in 57% (21 of 37), and metastatic in 11% (4 of 37). Of those with ocular disease, 67% (8 of 12) completed chemotherapy and all (8 of 8) achieved remission. In contrast, 48% (10 of 21) with orbital disease completed chemotherapy and only 50% (5 of 10) achieved remission. The difference in outcome between the groups was statistically significant (P = .001, Fisher exact test). Conclusion: The profile of retinoblastoma in Tanzania is skewed toward severe invasive disease. Despite the introduction of chemotherapy, further improvements in mortality and morbidity can only be achieved through emphasis on early detection. (Copyright 2012, SLACK Incorporated.) |
