Abstract:
BACKGROUND:There is limited information on the risk of metastatic breast cancer (MBC) to inform younger women, particularly those under 40 years. AIMS:We conducted a retrospective analysis of a population-based cohort study to describe the risk, site and prognosis of MBC in young women under 40 years with an initial diagnosis of non-metastatic breast cancer and compared with older women. METHODS:Data were extracted from the New South Wales Central Cancer Registry and the Admitted Patient Data Collection database between 2001-2007. Main outcome measures were 5-year cumulative incidence of MBC, prognostic factors for MBC and overall survival (OS) from the date of MBC diagnosis. RESULTS:Three hundred and ninety-five (6%) of 6640 women with non-metastatic BC were <40 years. The 5-year cumulative incidence of MBC was 24% (95% CI 20-29%) for women <40 years with non-metastatic BC, compared with 9% (95% CI 9-10%) for women ≥40 years. Significant independent risk factors for MBC ≤ 5 years were age <40, regional disease at diagnosis, low socioeconomic status and the presence of other non-breast primary. At first record of MBC, visceral sites were more common for women <40 years than ≥40 (54% vs 43%; P = 0.03). Median survival for women with MBC within 5 years was not significantly different between young and older women (<40 years 18 months vs ≥40 years 14 months; log-rank P = 0.21). CONCLUSIONS:Women with non-metastatic BC before age 40 have a higher 5-year risk of developing MBC than older women. There were no significant differences in median survival following MBC between young and older women.
