MP-SIR is a method used to perform multiple primary analyses and to test hypotheses that explore theoretical links in the etiology of two cancers. A defined cohort of persons previously diagnosed with cancer is followed through time to compare their subsequent cancer experience to the number of cancers that would be expected based on incidence rates for the general population.

MP-SMR follows a cohort of persons through time to compare their observed mortality experience to the expected mortality based on U.S. mortality rates.

Multiple Primary - Standardized Incidence/Mortality Ratios can be calculated in SEER*Stat.
