We used disability-adjusted life years (DALY) to estimate the cancer burden in Japan for the year 2000.
We estimated years of life lost (YLL) by using mortality data and years lived with disability (YLD) by using incidence data. The DALY for cancer was calculated as the sum of YLL and YLD.
For all cancers combined, 2 733 884 years of DALY were estimated in men and 2 091 874 years were estimated in women. Among men, stomach and lung cancers accounted for the largest proportions of DALY, followed by liver cancer and colorectal cancer. Among women, the greatest contributors to DALY were stomach, colorectal, breast, and lung cancers.
The national cancer burden in Japan was expressed in terms of DALY, which might be useful in assessing future changes with respect to mortality and morbidity in Japan.
我们使用伤残调整生命年(DALY)来估计 2000 年日本的癌症负担。
我们使用死亡率数据来估计生命损失年(YLL),使用发病数据来估计残疾生存年(YLD)。癌症的 DALY 计算为 YLL 和 YLD 的总和。
在所有癌症中,男性的 DALY 估计为 2733884 年,女性的 DALY 估计为 2091874 年。在男性中,胃癌和肺癌占 DALY 的比例最大,其次是肝癌和结直肠癌。在女性中,导致 DALY 最大的癌症为胃癌、结直肠癌、乳腺癌和肺癌。
日本的全国癌症负担用 DALY 表示,这可能有助于评估日本未来在死亡率和发病率方面的变化。
