Introduction
Breast cancer data has been collected in Scotland to support audit of performance against national standards since 1999. There has always been an ambition to collect routine data on recurrence but this remains challenging. In an attempt to progress, health boards were invited to contribute data on those patients diagnosed in 2007.
Methods
1490 patients diagnosed in 2007 with invasive breast cancer or ductal carcinoma in situ (DCIS) who underwent surgery were identified in Ayrshire & Arran, Borders, Fife, Grampian, Highland, Lothian and Shetland Health Boards. Data relating to cancer and deprivation scores were collected for analysis.
Results
Five year local recurrence rate for those with DCIS was 1.3% after mastectomy and 2.5% for breast conservation.
For invasive cancer, rates were 3.1% after mastectomy and 1.9% for breast conservation. 5 year survival was 86 and 91% respectively.
There was an apparent relationship between deprivation score and outcome for those undergoing breast conservation (but not mastectomy) with the most deprived quintile having 5 year survival of 93.8% while the least deprived had survival of 75.7% (p<0.0001).
Risk of local recurrence varied with age for those undergoing breast conservation (but not mastectomy) with rates of 3.7% for those under 50, 1.3% for 51-65, 3.1% for 66-75 and 6.2% for those over 75 (p=0.03).
Conclusions
Standards measured for those with cancer largely relate to treatment processes and are, at best, obliquely related to outcome. Local recurrence and survival data among those diagnosed with breast cancer are essential to truly assess outcome.
