Survival rates for cancer patients in Austria
from 1985 to 2005
The recent analysis included 758 266 cancer cases documented
from 1985 to 2009 by the Austrian National Cancer Registry. Several
crucial trends were detected, which are widely in line with international
findings. In the last 25 years a markedly gain in cancer survival was
observed, but we have to consider that all cancers combined represent
a broad variety of cancer diseases. Cancer stage at diagnosis, as well
as age and sex proved to be the strongest predictors of overall cancer
survival. The current analysis shows an improvement in 5-year cumulative relative survival from diagnoses in 1985 to diagnoses
in 2005 increasing from 44% to 62% (+18 percentage points) for both
sexes together, from 38% to 61% in men, and from 49% to 63% in
women. In other words, compared to the survival probability of the general
population the survival probability for a cancer patient diagnosed in
1985 for a time span of five years was only 0.44 times as high whereas
for a cancer patient diagnosed in 2005 it was already 0.62 times as
high. Generally, women have an advantage in cancer survival, but the
sex difference has diminished within the last decades as the gain in
survival has increased stronger in men. However, it is distressing that
the survival probability for patients whose tumors had already set metastases
at diagnosis did not really change over the years. Interpreting the
results of survival analysis one has to bear in mind several methodological
limits like lead-time bias and over-diagnosis. Those extend survival
time even if death is not postponed. As well quality of life cannot
be assessed with this method.
