TY - THES A1 - Steimer, Ann-Kathrin T1 - Adhärenz bei oraler Capecitabin-Therapie - Zusammenhänge mit Angststörungen T1 - Adherence to oral capecitabine therapy - Relation to anxiety disorders N2 - Laut Schätzungen des Robert Koch-Instituts erkranken jährlich fast 500.000 Personen an einer Krebserkrankung, mit steigender Tendenz. Durch stetige Fortschritte in der Forschung kam es durch die Entwicklung einer Chemotherapie in Tablettenform zu einem Paradigmenwechsel in der Krebstherapie. Für ein optimales Therapie-Outcome ist es von großer Bedeutung, dass die Patienten ein adhärentes Verhalten zeigen. Weiterhin zeigt sich in der bisherigen Literatur, dass psychische Komorbiditäten die Adhärenz und damit den Behandlungserfolg gleichermaßen beeinflussen können. Dies wurde in der vorliegenden Arbeit evaluiert. Die Studie umfasste insgesamt 69 Krebspatientinnen und -Patienten, die eine Chemotherapie mit Capecitabin erhielten. Untersucht wurden Gruppenunterschiede zwischen soziodemografischen und klinischen Variablen auf der einen Seite und Adhärenz auf der anderen Seite sowie die klinisch relevante Belastung durch Angstsymptome. Zur Datenerhebung wurden zum einen der MARS-Fragebogen zur Erfassung der Adhärenz und zum anderen der GAD-7 zur Erfassung der Angstsymptomatik verwendet. Adhärentes Verhalten in Bezug auf die Einnahme von Capecitabin zeigte sich bei 75.4% der Personen im untersuchten Studienkollektiv. Dieses Ergebnis steht in Einklang mit bisherigen Publikationen, die ebenfalls den Zusammenhang zwischen Adhärenz bei Capecitabin untersuchten. Die weitere Hypothese war, dass höhere Angstbelastungen unter Patienten signifikant mit einer verminderten Adhärenz in Zusammenhang stehen. Dies konnte in der vorliegenden Studie jedoch nicht festgestellt werden. Einerseits zeigte zwar nur ein geringer Anteil der untersuchten Patienten Hinweise einer Angststörung (7%), andererseits wurde festgestellt, dass nicht alle dieser Patienten eine psychotherapeutische Behandlung erhielten. Für zukünftige Forschungen wäre zu überlegen, weitere Messinstrumente zur Diagnostik einer niederschwelligen Angst einzusetzen. Weiterhin wären ein größeres Therapieangebot und umfassendere psychosoziale Unterstützung dringend erforderlich. Abschließend bleibt festzuhalten, dass in Zukunft weitere Studien, v.a. auch mit größeren Fallzahlen sowie Längsschnitt- oder Follow-up-Studien zu diesem Forschungsthema dringend indiziert sind. N2 - According to estimates by The Robert Koch Institute, almost 500,000 people are diagnosed with cancer every year, and the numbers are rising. Steady progress in research has led to a paradigm shift in cancer therapy with the development of chemotherapy in tablet form. For an optimal therapy outcome, it is of great importance that patients show adherent behavior. Furthermore, previously published literature shows that psychological comorbidities can equally influence adherence and thus treatment success. This is what has been evaluated and is presented in this paper. The study included a total number of 69 cancer patients receiving chemotherapy with capecitabine. Group differences were investigated between sociodemographic and clinical variables as well as adherence and the clinically relevant impact of anxiety symptoms. For data collection, the MARS questionnaire was used to assess adherence and the GAD-7 to assess anxiety symptoms. Adherence to capecitabine was shown in 75.4% of individuals in the study population examined. This result is consistent with previous publications that also examined the relationship between adherence to capecitabine. A further hypothesis was that higher anxiety levels amongst patients are significantly associated with reduced adherence. However, this could not be established in the present study. Although only a small proportion of the patients studied showed evidence of an anxiety disorder (7%), it was found that not all of these patients received psychotherapeutic treatment. For future research, it would be worth considering the use of additional measurement instruments for the diagnosis of low-threshold anxiety. Furthermore, a more extensive range of therapies and more comprehensive psychosocial support are urgently needed. In conclusion, further studies on this research topic should be conducted, particularly with a greater number of cases as well as longitudinal or follow-up studies.

Aspects of a close patient–doctor relationship are reported to be correlated with adherence to oral anticancer drugs, but data on capecitabine are scarce. Patients and methods: Sixty-four outpatients with a diagnosis of cancer and prescribed capecitabine were recruited from a German Comprehensive Cancer Center. We used the Patient–Doctor Relationship Questionnaire (PDRQ-9), the Medical Adherence Rating Scale (MARS), the Beliefs about Medicines Questionnaire (BMQ), and the Satisfaction with Information about Medicines Scale (SIMS) to assess patients’ perceptions and behavior. Medical data were extracted from the charts. Results: Non-adherence was reported by 20% of the 64 participants. The perceived quality of the patient–doctor relationship was high in general, but it did not emerge as a predictor of adherence in our survey (odds ratio [OR]=0.915, P=0.162, 95% CI=0.808–1.036). However, beliefs about medicine (OR=1.268, P<0.002; 95% CI=1.090–1.475) as well as satisfaction with information about medicine (OR=1.252, P<0.040, 95% CI=1.010–1.551) were predictors of adherence and the quality of the patient–doctor relationship was correlated with both variables (r=0.373, P=0.002 for SIMS sum score; r=0.263, P=0.036 for BMQ necessity/concern difference). Overall, adherence to capecitabine was high with a conviction that the therapy is necessary. However, concerns were expressed regarding the long-term effect of capecitabine use. Patients have unmet information needs regarding interactions of capecitabine with other medicines and the impairment of their intimate life. Conclusions: In order to ensure adherence to capecitabine, our results seem to encourage the default use of modern and perhaps more impersonal means of information brokerage (eg, email, internet). However, the contents of some of patients’ informational needs as well as the associations of patients’ beliefs and satisfaction about the information received suggest a benefit from a trustful patient–doctor relationship.

Detailed measures of FOP/FCR are needed because little is known about the knowledge of FOP/FCR, its associations with the patient–doctor relationship, and the rate of adequate therapy. Colorectal cancer (CRC) is one of the most prevalent cancer entities, and oral capecitabine is widely prescribed as treatment. Therefore, we initiated a pilot study to expand the literature on FOP/FCR in CRC outpatients receiving capecitabine and to generate hypotheses for future investigations. Methods: This study included 58 patients treated at a comprehensive cancer center. FOP/FCR was assessed with the Fear of Progression Questionnaire (FOP-Q-SF). Satisfaction with the relationships with doctors was assessed with the Patient–Doctor Relationship Questionnaire-9 (PRDQ-9). Levels of side effects were rated by the patients on a visual analog scale. Clinical data were extracted from the charts. Results: A total of 19 out of 58 patients (36%) suffered from FOP/FCR according to our assessment. Levels of FOP/FCR seemed to be mostly moderate to high. Only four out of the 19 distressed patients (21%) were treated accordingly. Typical side effects of oncological treatment were associated with higher FOP/FCR. Satisfaction with doctor–patient relationships was not associated with FOP/FCR. Regarding single items of FOP/FCR, three out of the five most prevalent fears were associated with close relatives. Discussion: FOP/FCR occurred frequently in more than one in three patients, but was mostly untreated in this sample of consecutive outpatients with CRC receiving oral capecitabine. In detail, most fears were related to family and friends. In addition to an unmet need of patients, our data indicate sources of distress not considered thus far. If replicated in larger studies, results may help to inform intervention development and improve patient care.
