Transition in cancer patterns among Turks residing in Germany.

Cancer mortality among the 2.1 million Turks residing in Germany is assumed to change from a pattern typical for a developing country towards one of an industrialised country. To test this hypothesis, we compared age-standardised cancer mortality rates among Turkish residents and (West) Germans using death registration data. In addition, we assessed proportional cancer incidence ratios among Turkish cases (n=144) in a German population-based cancer registry. All-cancer mortality 1992-1997 (per 100000) was 34.8 (n=4192) among Turkish men (Germans: 72.3) and 21.5 (n=1862) among Turkish women (Germans: 52.4). Over time, gastric and lung cancer mortality increased among Turkish men, as did breast cancer mortality among Turkish women. The proportional cancer incidence (PCIR) for stomach cancer among men was 2.9 (95% Confidence Interval (CI): 1.7-4.8), and that for breast cancer among women was 0.7 (95% CI: 0.4-1.1). Turks had an increased proportional incidence ratio for non-Hodgkin's lymphoma. Our findings partly support a transition of cancer patterns among Turks in Germany.
