Statistical profiles of malignant melanoma and other skin cancers in Japan: 2007 update

Abstract
In the previous report of the Prognosis and Statistical Investigation Committee of the Japanese Skin Cancer Society, we tabulated data on patients with malignant melanoma who had been registered at major medical institutions (22 institutions on average) in Japan over 5-year periods from 1987 to 1991 (group A) and from 1992 to 1996 (group B). In the present study, patients registered from 1997 to 2001 (group C) were investigated and the data were compared with findings obtained by the subsequent follow-up of groups A and B.
