Clinically detected gastroenteropancreatic neuroendocrine tumors are on the rise: Epidemiological changes in Germany

Figure 3 Absolute changes in the incidence of gastroenteropancreatic neuroendocrine tumor are shown according to tumor site and sex. A: Changes were calculated for the reference periods 1976-1978 and 2004-2006*; the periods 1979-1981 and 2004-2006 were chosen for the stomach, since no registered gastric NE neoplasms were registered in women before 1979; B: Changes in incidence are presented as absolute increments age-adjusted to the 1987 German standard population. The data shown originate from the former East German National Cancer Registry (DDR Krebsregister) for the years 1976-1978 or from its successor, the Joint Cancer Registry, for the time period 2004-2006. NE: Neuroendocrine.
