Appendix 2 - Stage

Stage presented in this report is the FIGO 2014 stage at diagnosis of the tumour. Tumour stages are numbered from 1 to 4, with a higher value indicating more advanced disease.

For the analysis of geographic variation in treatment stage 1 tumours were excluded as little regional variation in treatment was expected; almost all such tumours were treated with primary surgery only or surgery with adjuvant chemotherapy. If no staging data were available at the time of analysis, the corresponding tumour was defined as ‘stage not recorded’.
