About this study

Official title: Prospective and Retrospective Observation of the Adjuvant and Palliative Treatment Strategies in the Therapy of Colorectal Cancer in Germany

To describe treatment reality of patients with colorectal cancer treated by office-based and clinic-based medical oncologists in Germany.

Read the detailed description

The TKK is a prospective, longitudinal, nation wide cohort study with the purpose to record information on the antineoplastic treatment of colorectal cancer in Germany. The registry will follow patients for up to five years. It will identify common therapeutic sequences and changes in the treatment of the disease. At inclusion, data in patient characteristics, comorbidities, tumor characteristics, biomarker testing and previous treatments are collected. During the course of observation data on all systemic treatments, radiotherapies, surgeries, and outcome are documented.

The impact of nutrition (CoNut) and physical activity (CoNut) on the course of the adjuvant disease will be examined, as well as long-term effects of adjuvant treatment (CoTox) and the final phase of the palliative process (CoLife). Based on the available data a prognostic score will be developed.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Course of Antineoplastic Treatment (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00910819, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
