The Government of Trinidad and Tobago is in the process of developing a comprehensive National Oncology Programme. Regarding Paediatric Oncology, it is necessary to characterize this population to adequately direct its development. This report describes the incidence of childhood cancer in Trinidad and Tobago.
The data were extracted from the National Cancer Registry of Trinidad and Tobago and the Eric Williams Medical Sciences Complex. Malignancies were coded with the International Classification of Childhood Cancer, 3rd edition. Incidence rates were calculated for the period 2001-2006, age 0-14 years and by county.
The crude incidence rate of childhood cancer was 1.9 per 100,000 patient years (pyrs). One hundred and forty-five cases were reviewed for the six-year period with an incidence rate of 7.5 per 100,000 pyrs. The highest incidence was in children <5 years: 14 per 100,000 pyrs for males and 11.4 per 100,000 pyrs for females. Leukaemias and central nervous system tumours formed the majority of the cancers (58.6%), however nephroblastoma was more common than neuroblastoma especially in females <5 years: 2.7 per 100,000 pyrs compared with 1.2 per 100,000 pyrs for neuroblastoma. The incidence of all childhood cancers did not vary across counties, however there was a higher incidence of leukaemia in three counties.
The results provide insight into the incidence of childhood cancer in Trinidad and Tobago. It is lower than in developed countries. There are some unique findings in the incidence of nephroblastoma in girls less than five years of age and the relatively higher incidence of leukaemia in three counties. Further analysis is required in these areas.
特立尼达和多巴哥政府正在制定一项全面的国家肿瘤计划。关于儿科肿瘤学，有必要对这一人群进行特征描述，以便为其发展提供充分指导。本报告描述了特立尼达和多巴哥儿童癌症的发病率。
数据取自特立尼达和多巴哥国家癌症登记处以及埃里克·威廉姆斯医学科学综合大楼。恶性肿瘤按照《国际儿童癌症分类》第3版进行编码。计算了2001 - 2006年期间0至14岁儿童以及按县划分的发病率。
儿童癌症的粗发病率为每100,000人年1.9例。六年期间共审查了145例病例，发病率为每100,000人年7.5例。发病率最高的是5岁以下儿童：男性为每100,000人年14例，女性为每100,000人年11.4例。白血病和中枢神经系统肿瘤占癌症的大多数（58.6%），然而肾母细胞瘤比神经母细胞瘤更常见，尤其是在5岁以下女性中：每100,000人年2.7例，而神经母细胞瘤为每100,000人年1.2例。所有儿童癌症的发病率在各县之间没有差异，然而有三个县的白血病发病率较高。
这些结果为特立尼达和多巴哥儿童癌症的发病率提供了见解。其发病率低于发达国家。在5岁以下女孩肾母细胞瘤的发病率以及三个县白血病相对较高的发病率方面有一些独特的发现。这些领域需要进一步分析。
