  1. Obs. = Observed number of second primary cancers; SIR = standardised incidence ratio; CI = confidence interval; CNS = central nervous system; PCT = plasma cell tumours. SIRs shown in normal bold font indicate significantly increased risk; SIRs shown in bold italics indicate significantly decreased risk. SIRs for pancreatic cancer for the age groups 15-49 years and 50-64 years have been combined due to less than 5 observed cases aged 15-49 years.
