BACKGROUND: Cancer projections to the current year help in policy development, planning of programs and allocation of resources. We sought to provide an overview of the expected incidence and mortality of cancer in Canada in 2020 in follow-up to the report. METHODS: We obtained incidence data from the National Cancer Incidence Reporting System (1984-1991) and Canadian Cancer Registry (1992-2015). Mortality data (1984-2015) were obtained from the Canadian Vital Statistics - Death Database. All databases are maintained by Statistics Canada. Cancer incidence and mortality counts and age-standardized rates were projected to 2020 for 23 cancer types by sex and geographic region (provinces and territories) for all ages combined. RESULTS: An estimated 225 800 new cancer cases and 83 300 cancer deaths are expected in Canada in 2020. The most commonly diagnosed cancers are expected to be lung overall (29 800), breast in females (27 400) and prostate in males (23 300). Lung cancer is also expected to be the leading cause of cancer death, accounting for 25.5% of all cancer deaths, followed by colorectal (11.6%), pancreatic (6.4%) and breast (6.1%) cancers. Incidence and mortality rates will be generally higher in the eastern provinces than in the western provinces. INTERPRETATION: The number of cancer cases and deaths remains high in Canada and, owing to the growing and aging population, is expected to continue to increase. Although progress has been made in reducing deaths for most major cancers (breast, prostate and lung), there has been limited progress for pancreatic cancer, which is expected to be the third leading cause of cancer death in Canada in 2020. Additional efforts to improve uptake of existing programs, as well as to advance research, prevention, screening and treatment, are needed to address the cancer burden in Canada.
背景:对当年癌症数据的预测有助于政策制定、项目规划和资源分配。本研究旨在对 2017 年报告进行补充,概述 2020 年加拿大癌症发病和死亡情况。
方法:我们从国家癌症发病率报告系统(1984-1991 年)和加拿大癌症登记处(1992-2015 年)获得发病率数据。死亡率数据(1984-2015 年)来自加拿大生命统计-死亡数据库。所有数据库均由加拿大统计局维护。我们根据性别和地理区域(省份和地区)对所有年龄组人群的 23 种癌症类型的发病和死亡数据进行了统计,并计算了年龄标准化发病率,结果预测到 2020 年。
结果:预计 2020 年加拿大将有 225 800 例新发癌症病例和 83 300 例癌症死亡病例。预计最常见的癌症包括:肺癌(29 800 例)、女性乳腺癌(27 400 例)和男性前列腺癌(23 300 例)。肺癌预计仍是癌症死亡的主要原因,占所有癌症死亡的 25.5%,其次是结直肠癌(11.6%)、胰腺癌(6.4%)和乳腺癌(6.1%)。东部省份的发病率和死亡率一般高于西部省份。
结论:加拿大的癌症发病和死亡人数仍然居高不下,且由于人口不断增长和老龄化,预计这一数字还将继续上升。尽管在降低大多数主要癌症(乳腺癌、前列腺癌和肺癌)的死亡率方面已取得一定进展,但胰腺癌的进展有限,预计其将成为 2020 年加拿大第三大癌症死亡原因。为了应对加拿大的癌症负担,需要进一步努力提高现有项目的参与度,并推进癌症研究、预防、筛查和治疗。
