Abstract

Objective

To estimate the number of cancer-related deaths that could be attributed to spatial disparities in survival.

Design

Cohort study of cancer registry data.

Setting

Australia, 1 January 2010 to 31 December 2019.

Main outcome measures

The numbers and percentages of cancer-related deaths attributable to spatial disparities in survival were estimated by calculating the numbers of cancer-related deaths that would have occurred if all areas in Australia met or exceeded a benchmark 5-year survival rate. This benchmark corresponded to the survival rate of the area with survival better than 80% of all areas, with “area” referring to residential location at diagnosis.

Results

Of all 289 075 cancer-related deaths in Australia in 2010–2019, 33 892 (11.7%) were attributable to spatial disparities in survival. Although numbers were greatest in major cities, as remoteness and area disadvantage increased, the percentages of cancer-related deaths attributable to spatial disparities in survival increased. Of all cancer-related deaths in remote areas and the most socio-economically disadvantaged areas, 1569 of 5208 (30.1%) and 13 469 of 66 775 (20.2%) deaths were attributable to survival disparities, respectively. The highest numbers and percentages of attributable cancer deaths in remote areas were for rare cancers (529/1809 [29.3%]), lung cancer (300/1298 [23.1%]) and head and neck cancers (162/370 [43.8%]). In the most disadvantaged areas, rare cancers (3070/20 512 [15.0%]) and lung cancer (2640/18 057 [14.6%]) had the highest numbers of attributable cancer deaths.

Conclusions

These findings quantify the impact of spatial disparities in survival and highlight the need for equitable access to diagnostic and treatment services across Australia.

2010-2019年澳大利亚可归因于生存空间差异的癌症相关死亡人数：一项基于人群的回顾性队列研究

目的：估计可归因于生存空间差异的癌症相关死亡人数。设计：癌症登记资料的队列研究。地点：澳大利亚，2010年1月1日至2019年12月31日。主要结果测量：通过计算澳大利亚所有地区达到或超过基准5年生存率时发生的癌症相关死亡人数，估计由于生存空间差异导致的癌症相关死亡人数和百分比。该基准对应于所有地区中存活率高于80%的地区的生存率，“地区”指的是诊断时的居住地点。结果：2010-2019年澳大利亚28075例癌症相关死亡中，33892例（11.7%）可归因于生存的空间差异。虽然主要城市的人数最多，但随着偏远和地区不利因素的增加，由于生存的空间差异而导致的癌症相关死亡的百分比增加了。在偏远地区和社会经济最不利地区的所有癌症相关死亡中，5208例死亡中有1569例（30.1%）和66775例死亡中有13469例（20.2%）可归因于生存差异。偏远地区癌症死亡人数和百分比最高的是罕见癌症（529/1809[29.3%]）、肺癌（300/1298[23.1%]）和头颈部癌症（162/370[43.8%]）。在最贫困地区，罕见癌症（3070/ 20512[15.0%]）和肺癌（2640/ 18057[14.6%]）的可归因癌症死亡人数最多。结论：这些发现量化了生存空间差异的影响，并强调了在澳大利亚公平获得诊断和治疗服务的必要性。
