Cancer survival among XXXX of Turkish descent in Germany 1980-2005: a registry-based analysis.

@entity5 @entity1 @entity1778
BACKGROUND: Little is known about the effect of migrant status on @entity5 survival. We studied @entity5 survival among @entity1 of Turkish descent in the German Cancer Childhood Registry, one of the largest @entity5 registries worldwide. METHODS: We identified @entity1 of Turkish descent among @entity5 cases using a name-based approach. We compared 5-year survival probabilities of Turkish and other @entity1 in three time periods of diagnosis (1980-87, 1988-95, 1996-2005) using the Kaplan-Meier method and log-rank tests. RESULTS: The 5-year survival probability for all @entity5 among 1774 cases of Turkish descent (4.76% of all 37.259 cases) was 76.9% compared to 77.6% in the comparison group (all other cases; p = 0.15). We found no age- or sex-specific survival differences (p-values between p = 0.18 and p = 0.90). For the period 1980-87, the 5-year survival probability among Turkish @entity1 with @entity1778 was significantly lower (62% versus 75.8%; p < 0.0001), this remains unexplained. For more recently diagnosed @entity1778 , we saw no survival differences for Turkish and non-Turkish @entity1 . CONCLUSION: Our results suggest that nowadays Turkish migrant status has no bearing on the outcome of @entity5 therapies in Germany. The inclusion of currently more than 95% of all @entity5 cases in standardised treatment protocols is likely to contribute to this finding.
