前言证据表明，许多癌症危险因素在经历过监禁的人中被过度表达，关于癌症流行病学的数据对于这一人群来说是有限的。我们的目标是描述2000年加拿大安大略省收容的成年人的癌症患病率、发病率和死亡率。方法我们将2000年安大略省收容的48,166名成年人的数据与2012年的安大略省癌症登记数据联系起来。我们计算了2000年被拘留前10年的癌症患病率，2000年至2012年的发病率，以及2000年至2011年的死亡率。以年龄为标准，我们计算了与安大略省普通人口相比的发病率和死亡率。结果2000年，在省级监护中心入院时，10年癌症患病率男性为0.4%，女性为0.6%。2000年至2012年间，2.6%的男性和2.8%的女性被诊断出患有新的癌症。与一般人群相比，男性和女性的癌症标化发病率比分别为1.0(95%可信区间0.9-1.0)和0.9(95%可信区间0.7-1.0)，宫颈癌、头颈部、肝癌和肺癌的标化发病率显著增加。标化死亡率男性为1.6(95%可信区间1.4~1.7)，女性为1.4(95%可信区间1.0~1.9)，头颈、肝癌、肺癌标化死亡率显著升高。癌症预防应该包括那些经历过监禁的人，而监禁期间可能会提供干预的机会。
IntroductionEvidence suggests that many risk factors for cancer are overrepresented in people who experience incarceration, and data on cancer epidemiology are limited for this population. We aimed to describe cancer prevalence, incidence and mortality in adults admitted to provincial custody in Ontario, Canada in 2000.MethodsWe linked data on 48,166 adults admitted to provincial custody in Ontario in 2000 with Ontario Cancer Registry data to 2012. We calculated cancer prevalence in the 10 years prior to admission to custody in 2000, incidence between 2000 and 2012 and mortality between 2000 and 2011. Standardized for age, we calculated incidence and mortality ratios by sex compared to the general population of Ontario.ResultsThe 10-year cancer prevalence was 0.4% in men and 0.6% in women at admission to provincial custody in 2000. Between 2000 and 2012, 2.6% of men and 2.8% of women were diagnosed with new cancer. The standardized incidence ratio for cancer was 1.0 (95% CI 0.9-1.0) for men and 0.9 (95% CI 0.7-1.0) for women compared to the general population, and was significantly increased for cervical, head and neck, liver and lung cancers. The standardized mortality ratio was 1.6 (95% CI 1.4-1.7) in men and 1.4 (95% CI 1.0-1.9) in women, and was significantly increased for head and neck, liver, and lung cancers.ConclusionsThere is an excess burden of cancer in people who experience incarceration. Cancer prevention should include people who experience incarceration, and the period of incarceration may offer an opportunity for intervention.
