- Abstract
Our study aimed to provide a comprehensive overview of trends in incidence, survival, mortality and treatment of first primary invasive breast cancer (BC), according to age, stage and receptor subtype in the Netherlands between 1989 and 2017. Data from all women diagnosed with first primary stage I to IV BC (N = 320 249) were obtained from the Netherlands Cancer Registry. BC mortality and general population data were retrieved from Statistics Netherlands. Age‐standardised incidence and mortality rates were calculated with annual percentage change (APC) and average annual percentage change (AAPC) statistics. The relative survival (RS) was used as estimator for disease‐specific survival. The BC incidence for all BC patients combined significantly increased until 2013 from 126 to 158 per 100 000 person‐years, after which a declining trend was observed. Surgery became less extensive, but (neo‐)adjuvant systemic treatments and their combinations were given more frequently. The RS improved for all age groups and for most stages and receptor subtypes, but remained stable for all subtypes since 2012 to 2013 and since 2000 to 2009 for Stage IV BC at 15 years of follow‐up. Overall, the 5‐ and 10‐year RS increased from 76.8% (95% confidence interval [CI]: 76.1, 77.4) and 55.9% (95% CI: 54.7, 57.1) in 1989 to 1999 to 91.0% (95% CI: 90.5, 91.5) and 82.9% (95% CI: 82.2, 83.5), respectively, in 2010 to 2016. BC mortality improved regardless of age and overall decreased from 57 to 35 per 100 000 person‐years between 1989 and 2017. In conclusion, the BC incidence in the Netherlands has steadily increased since 1989, but the latest trends show promising declines. Survival improved markedly for most patients and the mortality decreased regardless of age. What's new? Studies that simultaneously capture incidence, survival, and mortality trends in breast cancer are scarce, and receptor subtype‐specific trends have remained largely unexplored. This study provides an up‐to‐date and comprehensive overview of first primary invasive breast cancer trends in the Netherlands in 1989 to 2017. Breast cancer incidence increased for all breast cancer patients combined until 2013, but the latest trends show a promising decline. Treatment strategies became more complex. Relative survival improved for all age groups and for most stages and receptor subtypes, and mortality decreased overall. The results may be useful in supporting healthcare management and informing current clinical practice.
