Hospital-based registry is an essential tool in the fight against cancer. We summarized the 2012 data of hospital-based cancer registries in eight cancer treatment hospitals in Nagano Prefecture and compared them with data from all over Japan, considering the ranking by registration frequency for colorectal, gastric, lung, breast and prostate cancers between Nagano Prefecture and the whole of Japan. Liver cancer in Nagano Prefecture showed a low frequency while uterine and bladder cancers showed high frequencies compared with the rest of the country. Pancreatic cancer in Nagano Prefecture received a rank of 10, which is higher than the national average. Compared with all over Japan the frequencies of gastric, lung, liver, and breast cancers in Nagano Prefecture were high for stage I and low for stage IV. Hospital-based cancer registries can be powerful tools for evaluating the epidemiology of cancer in Nagano Prefecture.
