Background: In Germany, about 20% of the total population have a migration background. Differences exist between migrants and non-migrants in terms of health care access and utilisation. Colorectal cancer is the second most common malignant tumour in Germany, and incidence, staging and survival chances depend, amongst other things, on ethnicity and lifestyle. The current study investigates whether stage at diagnosis differs between migrants and non-migrants with colorectal cancer in an area of high migration and attempts to identify factors that can explain any differences.
Methods/Design: Data on tumour and migration status will be collected for 1,200 consecutive patients that have received a new, histologically verified diagnosis of colorectal cancer in a high migration area in Germany in the previous three months. The recruitment process is expected to take 16 months and will include gastroenterological private practices and certified centres for intestinal diseases. Descriptive and analytical analysis will be performed: the distribution of variables for migrants versus non-migrants and participants versus non-participants will be analysed using appropriate χ2-, t-, F- or Wilcoxon tests. Multivariable, logistic regression models will be performed, with the dependent variable being the dichotomized stage of the tumour (UICC stage I versus more advanced than UICC stage I). Odds ratios and associated 95%-confidence intervals will be calculated. Furthermore, ordered logistic regression models will be estimated, with the exact stage of the tumour at diagnosis as the dependent variable. Predictors used in the ordered logistic regression will be patient characteristics that are specific to migrants as well as patient characteristics that are not. Interaction models will be estimated in order to investigate whether the effects of patient characteristics on stage of tumour at the time of the initial diagnosis is different in migrants, compared to non-migrants.
Discussion: An association of migration status or other socioeconomic variables with stage at diagnosis of colorectal cancer would be an important finding with respect to equal health care access among migrants. It would point to access barriers or different symptom appraisal and, in the long term, could contribute to the development of new health care concepts for migrants.
Trial registration: German Clinical Trials Register DRKS00005056.
Objective: Our aim was to explore whether general practitioners (GPs) communicate with cancer patients on complementary and integrative medicine (CIM) in a patient-centred and case-specific manner.
Methods: We designed two cases of standardised breast cancer patients and allocated 29 GPs to hold a consultation either with Case 1 or Case 2. Case 1 presented with fears of possible physical side effects of hormone treatment. Case 2 feared a loss in social functioning because of nausea and emesis as possible side effects of chemotherapy. Consultations were audiotaped and analysed using the Roter Interaction Analysis System (RIAS). We analysed whether recommended CIM treatments and GPs' focus on psychosocial or medical and therapy-related content differed according to whether they were counselling Case 1 or Case 2.
Results: In consultations with Case 1, GPs rather focused on medical and therapy-related content and most often recommended mistletoe, diets and sports. In contrast, GPs focused on psychosocial content and they most often recommended methods of self-care when counselling Case 2.
Conclusion: The GPs in our sample reacted case-specifically to the patients' interest in CIM. Such responsive and patient-centred communication is a valuable resource but is often time-consuming. Adequate training and reimbursement should therefore be considered for GPs.
