Introduction: The UK was the first country to operate a 3 yearly National Breast Screening Programme (NBSP) for all women aged between 50 – 70 years. The aim of an effective screening programme is to improve survival through early detection of cancers before they are advanced. Our study investigates if Nottingham Prognostic Indicator (NPI) scores for tumours, both screened and symptomatic, have decreased over the years.
Method: A local prospectively collated database of patients presenting with a breast tumour between 1/1/1998 – 31/12/2015 was retrospectively analysed. For each patient we identified age on presentation, tumour size, tumour grade, node status and NPI score. The cases were separated into those presenting through the NBSP and symptomatic cases. The pathological characteristics of patients were compared and statistically analysed according to year groups.
Results: There was a total of 1048 patients; 253 screen detected and 795 symptomatic. Average age at presentation was stable throughout ranging from 59 -66 years old. Grouping the data into 5 year intervals shows there has been a reduction in tumour size, NPI and node positive disease in all new cancers but most dramatically in the screening group of patients.
Conclusion: Our findings suggest that since the introduction of screening there has been a trend towards a reduction in NPI, tumour size and node positive status in symptomatic and screened cancers. This implies a better prognosis and reduced mortality in patients with breast cancer, independent of advances in treatment.
