Trends in mortality from non-Hodgkin's lymphomas.

Trends in death certification rates from non-Hodgkin's lymphomas (NHL) were analyzed on the basis of the World Health Organization database over the period 1969-1998. Until the late 1970s, mortality from NHL was similar in the European Union (EU), the USA and Japan, i.e. around 3/100,000 males and 2/100,000 females. Over the last two decades, NHL mortality in the EU rose to 4.4/100,000 males and 2.8/100,000 females. Upward trends were greater in the USA, whose rates approached 6/100,000 males and 4/100,000 females in the late 1990s, and were observed in Japan, too.
