CEO Mr Gilman Wong said the company's better financial performance was driven by higher demand for its SIR-Spheres Y-90 resin microspheres radiotherapy treatment for liver cancer.
"This, coupled with price rises in key markets, favourable exchange rate and controlled growth in operating expenditures over the period resulted in out full year earnings growth materially outpacing volume growth as measure by dose sales," said Mr Wong.
Dose sales rose 19.8 per cent and revenue 36.1 per cent to $176 million.
The company said growth in dose sales reflected greater acceptance of its product by the oncology community, coupled with increased investment in its sales and marketing infrastructure.
