Female breast cancer treatment and survival in South Australia: Results from linked health data.

ABSTRACT:

Objective

We investigated treatment and survival by clinical and sociodemographic characteristics for service evaluation using linked data.

Method

Data on invasive female breast cancers (n = 13,494) from the South Australian Cancer Registry (2000-2014 diagnoses) were linked to hospital inpatient, radiotherapy and universal health insurance data. Treatments ≤12 months from diagnosis and survival were analysed, using adjusted odds ratios (aORs) from logistic regression, and adjusted sub-hazard ratios (aSHRs) from competing risk regression.

Results and conclusion

Five-year disease-specific survival increased to 91% for 2010-2014. Most women had breast surgery (90%), systemic therapy (72%) and radiotherapy (60%). Less treatment applied for ages 80+ vs <50 years (aOR 0.10,
