The comparison among the RTT, RTRo and RCR confirmed that the number of tumors considered MPs may be modified depending on the rules adopted. There were minor differences between the RTT and the RTRo since their rules were very similar. Most differences in agreement were with the RCR since its classification was conceptually different from the other two. The result on agreement with IARC-IACR rules is encouraging from the point of view of conducting a cooperative study among different registries on the incidence of MPs.
