Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Assessment of the effectiveness of care in certified cancer centres for eight cancer entities via a retrospective cohort study based on secondary data from statutory health insurance funds and population-based clinical cancer registries.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cancer constitutes the second most frequent cause of death in Germany. To maintain a high quality of treatment, the national cancer plan aims at a unified certification of cancer centres.

The project "Wirksamkeit der Versorgung in onkologischen Zentren" (WiZen) investigates effects of treatments in certified cancer centres across large populations and different cancer entities in comparison to hospitals that do not hold a certificate.

WiZen is a retrospective comparative cohort study that analyzes incident cases of eight types of cancer diagnosed within 2009-2017 based on nationwide health insurance data provided by WIdO (the AOK research institute) and data from regional clinical cancer registries (CCR) for the period 2006-2017. These eight types of cancer are colorectal cancer, pancreatic cancer, breast cancer, gynecologic tumors, lung cancer, prostate cancer, head and neck tumors and neuro-oncological tumors.
