“…Earlier, we reported the incidence of retinoblastoma in children under the age of 5 and 10 years in Taiwan from 1979 to 1996. 8 The present analysis includes more cases over a longer period. Moreover, as the TNCR is continually updated and the data entries are regularly checked and corrected, the results reported in this study are believed to be more accurate and complete than in the earlier report.…”

Purpose To describe the incidence and survival rate of patients with retinoblastoma in Taiwan over a 25-year period, from 1979 to 2003. Methods Cases of retinoblastoma have been reported to the Taiwan National Cancer Registry (TNCR) since 1979. Retinoblastoma data from 1979 to 2003 were retrieved from the TNCR databank for analysis of both the incidence and survival rate. Trends in the incidence rate were estimated by calculating the annual percentage change (APC).Results From 1979 to 2003, a total of 380 patients (182 [47.9%] females) with retinoblastoma were identified. Of the 380 cases, 359 patients (94.5%) were diagnosed before 5 years of age. The average annual agestandardized incidence rate was 4.45 per million in children under 10 years of age and 8.58 per million in children under 5 years of age. There was a significant increasing trend in the incidence rate over the study period with an APC of 2.3% (P ¼ 0.035). Before the implementation of Taiwan's National Health Insurance (NHI) Program in 1995, the mean age at diagnosis was 4.8 ± 13.3 years and the 5-year survival rate was 74.7%. After implementation of the NIH Program, the mean age at diagnosis decreased to 1.6 ± 2.1 years (Po0.001) and the 5-year survival rate increased to 84.7% (P ¼ 0.063). Conclusions We report the first populationbased study on retinoblastoma in Taiwan. There was a significant increasing trend in the incidence rate from 1979 to 2003. Since the implementation of Taiwan's NHI, the mean diagnostic age decreased.

“…[2][3][4] The third and fourth most common tumours, adenocarcinomas and adenoid cystic carcinomas, also compare with the rest of the world. [2][3][4] This suggests there are no geographical differences in relative frequencies of orbital tumour types (see Table 2), as there are for uveal melanoma and retinoblastoma. [2][3][4] Other studies report squamous cell carcinoma (SCC) as the second most common tumour type, instead of rhabdomyosarcoma in our study.…”

Aims To describe the incidence and relative frequencies of primary malignant orbital tumours in the Netherlands from 1989 to 2006. Methods All registered primary malignant orbital tumours were extracted from the population-based database of the Netherlands Cancer Registry. Age-adjusted incidence of malignant orbital tumours per 10 000 000 persons per year and the estimated annual percentage change (EAPC) were computed. Results A total of 367 malignant orbital tumours were registered. The average age-adjusted incidence of malignant orbital tumours is 10.9. Lymphoma has a relative frequency of 67%, rhabdomyosarcoma 12%, adenocarcinoma 6%, and adenoid cystic carcinoma 5%. The incidence of primary malignant orbital tumours has been increasing in the Netherlands (EAPC þ 2.8%). Conclusion In the Netherlands, lymphoma is the most common primary malignant orbital tumour, followed by rhabdomyosarcoma, adenocarcinoma, and adenoid cystic carcinoma. The relative frequencies of the different histological tumour types are comparable to the frequencies in other parts of the world. The incidence of malignant primary orbital tumours shows a slight increase between 1989 and 2006.
