Migrants from Eastern Europe constitute more than 5% of Germany's population. Since population health in their countries origin is poor status upon arrival may be worse that the native-born German (hypothesis H1). As a minority, they socio-economically disadvantaged (H2), and deteriorate quickly (H3). We compared data 1995 2000 for immigrants (n = 353) random sample age-matched Germans 2, 824) Socioeconomic Panel. tested H1-3 using satisfaction, as proxy status, socioeconomic indicators....

Abstract Background Despite obvious advances over the last decades, locally advanced adenocarcinomas of gastroesophageal junction (GEJ) still carry a dismal prognosis with overall 5-year survival rates less than 50% even when using modern optimized treatment protocols such as perioperative chemotherapy based on FLOT regimen or radiochemotherapy. Therefore question remains whether neoadjuvant radiochemotherapy is eliciting best results in patients GEJ cancer. Hence, an adequately powered...
