Brief Summary:

Efficacy and safety of a supportive treatment with European mistletoe extract Iscador® Qu ("quercus", i.e. from oak tree) in patients with colorectal cancer (Union for International Cancer Control, UICC stages II-IV), in addition to post-operative conventional oncological therapy (radio-, chemo-, targeted therapy) as compared to a parallel group with conventional therapy only.

Primary Endpoints: Reduction of adverse effects of conventional therapy; reduction of therapy or disease induced symptoms (both are quality of life parameters and evaluated after 1 year); prolongation of disease free and/or overall survival (DFS, OS) after 5 years.

Prospective observational confirmation study of previous retrospective cohort study.

As this is a non-interventional cohort study, all therapies and measurements are performed on directive by the treating physician and/or request by the patient only.

Study Type : Observational
Estimated Enrollment : 300 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Prospective Epidemiological Study to Expand Knowledge on Efficacy and Safety of a Routine Post-operative Supportive Therapy With the Mistletoe Extract Iscador® Qu Within Oncological Treatment of Colorectal Cancer Stages UICC II-IV
Study Start Date : September 2010
Estimated Primary Completion Date : December 2016
Estimated Study Completion Date : June 2017

Test group with Iscador® Qu
The test group will receive the mistletoe extract Iscador® Qu as supportive treatment in addition to post-operative conventional oncological therapy (radio-, chemo-, targeted therapy).
Control group
The parallel control group will receive no mistletoe but only post-operative conventional oncological therapy (radio-, chemo-, targeted therapy).

Primary Outcome Measures :
  1. Disease-free survival time (DFS). [ Time Frame: 5 years ]

Secondary Outcome Measures :
  1. Number of patients with at least one therapy or disease induced symptom (surrogate parameter for quality of life) [ Time Frame: 1 year ]
    As key symptom, the fatigue syndrome will be evaluated separately.

  2. Mean values of Karnofsky performance status, Eastern Cooperative Oncology Group (ECOG) score [ Time Frame: 1 year ]
  3. Interim analysis on overall survival time (OS) in UICC stage IV patients [ Time Frame: 2 years ]
  4. Safety of Iscador® Qu (number of patients with systemic or local adverse events (AE) to Iscador® Qu) [ Time Frame: 5 years ]
    Adverse events (local and/or systemic) contributable to Iscador® Qu

  5. Number of patients with unexpected adverse events (UAE) contributed to conventional oncological therapy (radio-, chemo-, targeted therapy). [ Time Frame: 1 year ]
