 Based on data from the JSCCR registry(1974-2004)and the JAAD(2000-2009), statistics of appendiceal malignancies(AMs)in the Japanese population were reviewed. The incidence of AMs was 0.2% in the surgical cases of the JSCCR registry and 0.08% in the autopsy cases of the JAAD, and there was an increasing trend in the incidence over the past 30years. Peak ages at time of diagnosis ranged from the 60s to 70s. The most common histology of the AMs was well to moderately differentiated adenocarcinoma, followed by mucinous carcinoma, signet ring cell carcinoma, poorly differentiated adenocarcinoma, and carcinoid tumor. The proportions of histological types differed considerably from those of the SEER data of the USA. The prognosis of the patients with appendiceal carcinoma was worse compared with colorectal cancer, and it was particularly true for patients with positive nodal involvement.
