Cancer is a leading cause of death worldwide accounting for 7.4 million deaths. Cancer has become a major public health concern in Algeria. The aim of the present study was to estimate cancer incidence in Mascara Province based on the population-based cancer registry. We analyzed data from the cancer registry of Mascara covering all cancer cases diagnosed by all methods and included in the registry from 1(st) January 2000 to 31(st) December 2010. The results are presented as incidence rates of cases by site, sex, age, and crude rate. Age-standardized rates per 100,000 person-years (ASRs) were calculated, using the direct method of standardization to the world population. A total of 1875 cases of invasive cancer were recorded. The mean age of diagnosis for all cancers was 52.66 ± 0.5 in men and 59.18 ± 0.6 in women. The ASR for all cancers in females was 27.8 per 100,000, and that for males was 23.6 per 100,000. The most important finding of the present study was the high incidence of liver cancer among males and females in Mascara. Among females, breast cancer was the most frequently reported followed by Cervix uteri, liver and colon. The most frequent cancer types in males were lung, colon, esophagus and stomach and liver. Cancer incidence in Mascara province was lower than that reported in other national and regional registries. Findings of the present study revealed high incidence of liver cancer in the province, the highest in Algeria, suggesting high prevalence of risk factors.
癌症是全球主要死因之一，导致740万人死亡。癌症已成为阿尔及利亚的一个主要公共卫生问题。本研究的目的是基于人群癌症登记处来估计马斯卡拉省的癌症发病率。我们分析了马斯卡拉癌症登记处的数据，涵盖了2000年1月1日至2010年12月31日期间通过各种方法诊断并纳入登记处的所有癌症病例。结果以按部位、性别、年龄分类的病例发病率以及粗发病率呈现。采用直接标准化法将年龄标准化率计算为每10万人年的年龄标准化率（ASRs），以世界人口为标准。共记录了1875例浸润性癌症病例。所有癌症的男性诊断平均年龄为52.66±0.5岁，女性为59.18±0.6岁。女性所有癌症的年龄标准化率为每10万人27.8例，男性为每10万人23.6例。本研究最重要的发现是马斯卡拉省男性和女性肝癌的高发病率。在女性中，乳腺癌报告最为频繁，其次是子宫颈癌、肝癌和结肠癌。男性中最常见的癌症类型是肺癌、结肠癌、食管癌、胃癌和肝癌。马斯卡拉省的癌症发病率低于其他国家和地区登记处报告的发病率。本研究结果显示该省肝癌发病率高，是阿尔及利亚最高的，这表明风险因素的高流行率。
