Evidence against the proposition that "UK cancer survival statistics are misleading": simulation study with National Cancer Registry data.
TLDR
Even implausibly extreme levels of the hypothesised errors in the cancer registry data could not explain the international differences in survival observed between the UK and other European countries.Abstract:
Objectives To simulate each of two hypothesised errors in the National Cancer Registry (recording of the date of recurrence of cancer, instead of the date of diagnosis, for registrations initiated from a death certificate; long term survivors who are never notified to the registry), to estimate their possible effect on relative survival, and to establish whether lower survival in the UK might be due to one or both of these errors. Design Simulation study. Setting National Cancer Registry of England and Wales. Population Patients diagnosed as having breast (women), lung, or colorectal cancer during 1995-2007 in England and Wales, with follow-up to 31 December 2007. Main outcome measure Mean absolute percentage change in one year and five year relative survival associated with each simulated error. Results To explain the differences in one year survival after breast cancer between England and Sweden, under the first hypothesis, date of diagnosis would have to have been incorrectly recorded by an average of more than a year for more than 70% of women known to be dead. Alternatively, under the second hypothesis, failure to register even 40% of long term survivors would explain less than half the difference in one year survival. Results were similar for lung and colorectal cancers. Conclusions Even implausibly extreme levels of the hypothesised errors in the cancer registry data could not explain the international differences in survival observed between the UK and other European countries.read more

TL;DR: The major advances in cancer management that occurred up to 2007 seem to have resulted in improved survival in Europe, although results for lung cancer in some regions (central and eastern Europe) might be affected by overestimation.

TL;DR: Progress in cancer control over the study period was evident for stomach, colon, lung (in males), and ovarian cancer, and the impact of comorbidity are likely the main determinants of patient outcomes.

TL;DR: Differences in stage at diagnosis partly explain international differences in colorectal cancer survival, with a more adverse stage distribution contributing to comparatively low survival in Denmark.

TL;DR: The 5‐year relative survival and the percentage ‘cured’ increased for patients aged under 70 years at diagnosis during 1971–2006, but advancing age was associated with poorer outcome, and the long‐term outcome of patients with AML has improved substantially.

TL;DR: This is, to the authors' knowledge, the first worldwide analysis of cancer survival, with standard quality-control procedures and identical analytic methods for all datasets, and should eventually facilitate joint assessment of international trends in incidence, survival, and mortality as indicators of cancer control.

TL;DR: In this paper, the first study in a programme to investigate international survival disparities, with the aim of informing health policy to raise standards and reduce inequalities in survival, was presented, where data from population-based cancer registries in 12 jurisdictions in six countries were provided for 2·4 million adults diagnosed with primary colorectal, lung, breast, ovarian, or ovarian cancer during 1995-2007, with follow-up to Dec 31, 2007.

TL;DR: Increases in survival and decreases in geographic differences over time, which are mainly due to improvements in health-care services in countries with poor survival, might indicate better cancer care in wealthy countries with high TNEH.
