Few population-based cancer registries are in place in developing countries. In order to know the burden of cancer in Moroccan population, cancer registry initiative was put in place in the Casablanca district, the biggest city of Morocco.
The data collected covers 3.6 millions inhabitant and included Casablanca city and the administrative region.
The data collected in the years 2005-07 show that the top 5 forms of cancers in women were breast (ASR: 36.4 per 100,000), cervical (15.0), thyroid (6.7), colon-rectum (5.8), and ovarian (5.3); the top 5 cancers in men were lung (25.9), prostate (13.5), bladder (8.7), colon-rectum (8.1) and non-Hodgkin lymphoma (7.2). Tumours of haematopoietic and lymphoid tissues represented 11% of all cancers (skin excluded); some presented unusual sex ratios. For breast, cervical, colorectal and thyroid cancer, respectively 57%, 42%, 28% and 60% of the cases were under 50 years of age. This was attributable to particularly low numbers of cases recorded among old people, and the young age of the general population; the observed age-specific incidences under age 50 were not higher than in western countries. Cancers at young ages were particularly common in women: 67% of the cases were under 50. Stage at diagnosis could be obtained for 82% of the breast cancer cases and was as follows: 28% local, 63% regional and 9% distant, in the absence of screening.
These first population-based data have provided an invaluable resource for the national cancer control plan of Morocco, and will be useful tool to its future evaluation.
发展中国家很少有基于人群的癌症登记处。为了了解摩洛哥人群的癌症负担，在摩洛哥最大的城市卡萨布兰卡地区开展了癌症登记倡议。
收集的数据涵盖360万居民，包括卡萨布兰卡市及其行政区。
2005 - 2007年收集的数据显示，女性中排名前5的癌症类型为乳腺癌（年龄标准化发病率：每10万人中36.4例）、宫颈癌（15.0）、甲状腺癌（6.7）、结直肠癌（5.8）和卵巢癌（5.3）；男性中排名前5的癌症为肺癌（25.9）、前列腺癌（13.5）、膀胱癌（8.7）、结直肠癌（8.1）和非霍奇金淋巴瘤（7.2）。造血和淋巴组织肿瘤占所有癌症（不包括皮肤癌）的11%；一些呈现出不同寻常的性别比。对于乳腺癌、宫颈癌、结直肠癌和甲状腺癌，分别有57%、42%、28%和60%的病例年龄在50岁以下。这归因于老年人中记录的病例数特别少以及总体人群年龄较轻；50岁以下观察到的年龄别发病率并不高于西方国家。年轻女性患癌尤为常见：67%的病例年龄在50岁以下。在没有筛查的情况下，82%的乳腺癌病例能够获得诊断分期，情况如下：28%为局部期，63%为区域期，9%为远处期。
这些首批基于人群的数据为摩洛哥的国家癌症控制计划提供了宝贵资源，并且将成为未来评估的有用工具。
