Abstract

Cancer as a cause of death has been constantly increasing in Japan, and it became the leading cause of death in 1981. As for incidence and survival, the research groups financed by the Health, Labour and Welfare Ministry have estimated the national cancer incidence in Japan based on high-quality data from several cancer registries over a long period. With the enactment of the Act on Promotion of Cancer Registries in 2013, cancer became a reportable disease; this allows us to establish a cancer control program based on reliable statistics. Cancer mortality and incidence in 2014 describe the cancer burden in the country precisely. Age-standardized mortality rates (world population) for males and females were 114.8 and 63.0/100,000, respectively. Age-standardized incidence rates for males and females were 303.1 and 224.8/100,000, respectively. According to the results of an international collaborative study, CONCORD-3, Japan demonstrated good results, such as net survival of 60.3% for stomach cancer. The 5-year prevalence for all cancers was 1,734,060 in males and 1,399,380 in females. The recent trends of cancer mortality and incidence showed that no increase of mortality was observed in any primary sites in males. However in females, uterine cancer, both of the cervix and the uterine body, showed increasing mortality. Mortality in all the other primary sites is decreasing or at least leveling off. As for incidence, cancers of the pancreas, prostate, and thyroid and malignant lymphoma were increasing in males, and cancers of the esophagus, colon and rectum, lung, breast, uterus, ovary, and thyroid and malignant lymphoma were increasing in females. Geographical disparities at these sites were associated with well-known risk factors, such as smoking, salt intake, hepatitis C virus infection, and Helicobacter pylori infection. Given its hyper-aging society, Japan will likely face a substantial increase in the number of elderly cancer patients. This heavy cancer burden will be compounded by the functional limitations and co-morbidities that often present in older cancer patients. Cancer statistics and cancer registration in Japan in accordance with legislation are the keys to performing effective evidence-based cancer control.
基于癌症最新统计数据的日本癌症负担:需要循证癌症控制计划
癌症作为一种死亡原因在日本不断增加,并于1981年成为主要死亡原因。关于发病率和存活率,由厚生劳动省资助的研究小组根据来自几个癌症登记处的长期高质量数据,估计了日本全国癌症发病率。随着2013年《癌症登记促进法》的颁布,癌症成为一种可报告的疾病;这使我们能够建立一个基于可靠统计的癌症控制计划。2014年癌症的死亡率和发病率准确地描述了该国癌症的负担。男性和女性的年龄标准化死亡率(世界人口)分别为114.8和63.0/100000。男性和女性的年龄标准化发病率分别为303.1和224.8/10万。根据一项国际合作研究的结果,日本的CONCORD-3显示了良好的结果,如癌症的净存活率为60.3%。所有癌症的5年患病率男性为1734060,女性为1399380。癌症死亡率和发病率的最新趋势表明,在男性的任何原发部位都没有观察到死亡率的增加。然而,在女性中,子宫颈和子宫体的癌症死亡率都在增加。所有其他原发部位的死亡率都在下降或至少趋于平稳。就发病率而言,男性胰腺癌、前列腺癌、甲状腺癌和恶性淋巴瘤的发病率在增加,女性食道癌、结肠癌和直肠癌、肺癌、乳腺癌、子宫癌、卵巢癌和甲状腺癌以及恶性淋巴瘤的患病率在增加。这些地点的地理差异与众所周知的风险因素有关,如吸烟、盐摄入、丙型肝炎病毒感染和幽门螺杆菌感染。鉴于日本社会的超老龄化,日本可能会面临癌症老年患者数量的大幅增加。这种沉重的癌症负担将因老年癌症患者的功能限制和并发症而加剧。癌症统计数据和日本癌症立法登记是进行有效循证癌症控制的关键。
