  1. Obs. = Observed number of second primary cancers; SIR = standardised incidence ratio; CI = confidence interval; n.a. = not applicable; 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
