Survival after cancer is improving significantly in Australia, especially
among the better-off groups in the population, according to a report.
The report shows that between mid-1980s and early 2000s, the relative
chances of surviving five years after a diagnosis of cancer increased
significantly.
The increase was generally greater for men than for women, with all-cancer
five-year relative survival for men increasing from 41 percent in 1982-1986
to 58 percent for those diagnosed in 1998-2004.
Women maintained a higher survival overall, although with a smaller relative
increase over the same period - from 53 percent to 64 percent.
'The greatest increases in survival were seen in the 50 to 69 year age
range. This was due, at least in part, to screening programmes,' said Mark
Short of the Australian Institute of Health and Welfare's (AIHW) Health
Registers and Cancer Monitoring Unit.
Not all cancers showed the same improvement over the period. The best
improvements were seen in prostate cancer, kidney cancer, breast cancer and
non-Hodgkin lymphoma. The least improvement was for brain cancer, which
showed no significant change in survival.
The cancers with the highest five-year survival in the 1998-2004 period were
testicular cancer (97 percent), thyroid cancer (93 percent), melanoma (92
percent), breast cancer (88 percent) and prostate cancer (85 percent).
Cancers with the lowest relative survival were pancreatic cancer, lung
cancer, brain cancer, stomach cancer and cancer of unknown primary site.
For childhood cancers there was a large increase in five-year survival for
leukaemia, from 64 percent in 1982-1986 to 83 percent in 1998-2004. But
there was little change for the next most common cancers in children -
cancers of the brain, bone and connective issue.
Like many other health indicators, cancer survival is not as good among
people living in low socioeconomic status areas and in rural and remote
Australia.
All-cancer five-year relative survival for both men and women was lower for
those in low versus high socioeconomic status areas (54 percent compared to
65 percent for men and 61 percent compared to 68 percent for women). The
greatest difference was apparent in non-Hodgkin lymphoma and cervical
cancer.
David Currow, chief executive officer of Cancer Australia, said the findings
would assist in developing future cancer control activities.
These findings were presented in a report released by AIHW.
