Tissue registry study

Summary

Tissue registries were started in 1973 under the auspices of Hiroshima Prefectural Medical Association and in 1974 by Nagasaki City Medical Association. Pathology slides and pathology reports are collected for each tumor, malignant and benign. Tissue registry and tumor registry data from each city are processed at RERF, and crosschecked with the RERF’s study population with permission of each registry. The tissue registries provide a supplemental source for tumor case ascertainment for the tumor registries and were especially valuable in the early years, when there was difficulty in seeking collaboration from certain hospitals in Hiroshima. A large number of pathology slides collected and stored at one location greatly facilitates the conduct of our many site-specific studies involving pathology reviews of cases diagnosed over many years. The Hiroshima and Nagasaki tissue registries will continue to provide updated cancer incidence data that serve as the basis for a series of LSS site-specific cancer incidence studies discussed in RP 9-88.

As of April 2005 the Tissue Registry of the Hiroshima Prefectural Medical Association has been integrated with the Hiroshima Prefecture Cancer Registry, and as of April 2008 the Tissue Registry in Nagasaki was integrated with the Nagasaki Prefecture Cancer Registry so that the tissue registry is in compliance with the Personal Information Protection Law.
