Each year, the American Cancer Society estimates the numbers of new cancer cases and deaths in the United States and compiles the most recent data on population-based cancer occurrence and outcomes. Incidence data (through 2018) were collected by the Surveillance, Epidemiology, and End Results program; the National Program of Cancer Registries; and the North American Association of Central Cancer Registries. Mortality data (through 2019) were collected by the National Center for Health Statistics. In 2022, 1,918,030 new cancer cases and 609,360 cancer deaths are projected to occur in the United States, including approximately 350 deaths per day from lung cancer, the leading cause of cancer death. Incidence during 2014 through 2018 continued a slow increase for female breast cancer (by 0.5% annually) and remained stable for prostate cancer, despite a 4% to 6% annual increase for advanced disease since 2011. Consequently, the proportion of prostate cancer diagnosed at a distant stage increased from 3.9% to 8.2% over the past decade. In contrast, lung cancer incidence continued to decline steeply for advanced disease while rates for localized-stage increased suddenly by 4.5% annually, contributing to gains both in the proportion of localized-stage diagnoses (from 17% in 2004 to 28% in 2018) and 3-year relative survival (from 21% to 31%). Mortality patterns reflect incidence trends, with declines accelerating for lung cancer, slowing for breast cancer, and stabilizing for prostate cancer. In summary, progress has stagnated for breast and prostate cancers but strengthened for lung cancer, coinciding with changes in medical practice related to cancer screening and/or treatment. More targeted cancer control interventions and investment in improved early detection and treatment would facilitate reductions in cancer mortality.
每年,美国癌症协会都会预估美国新癌症病例和死亡人数,并汇编最新的基于人群的癌症发病和结果数据。发病率数据(截至 2018 年)由监测、流行病学和最终结果计划、国家癌症登记处计划和北美癌症登记处协会收集。死亡率数据(截至 2019 年)由国家卫生统计中心收集。2022 年,预计美国将有 1,918,030 例新癌症病例和 609,360 例癌症死亡,其中每天约有 350 人死于肺癌,这是癌症死亡的主要原因。2014 年至 2018 年期间,女性乳腺癌的发病率(每年增长 0.5%)继续缓慢上升,而前列腺癌的发病率保持稳定,尽管自 2011 年以来,晚期疾病的发病率每年增加 4%至 6%。因此,过去十年间,远处阶段诊断出的前列腺癌比例从 3.9%上升到 8.2%。相比之下,肺癌的晚期疾病发病率继续急剧下降,而局部阶段的发病率却突然每年增加 4.5%,这导致局部阶段诊断的比例(从 2004 年的 17%增加到 2018 年的 28%)和 3 年相对生存率(从 21%增加到 31%)都有所提高。死亡率模式反映了发病趋势,肺癌的死亡率下降加速,乳腺癌的死亡率下降放缓,前列腺癌的死亡率趋于稳定。总之,乳腺癌和前列腺癌的进展已经停滞,但肺癌的进展有所加强,这与癌症筛查和/或治疗相关的医疗实践变化相一致。更有针对性的癌症控制干预措施和对改进早期发现和治疗的投资,将有助于降低癌症死亡率。
