NCT01570010

Brief Summary

The current study is designed to gain a better understanding of the role of a healthy diet aimed at dampening inflammation and oxidative stress on long-term disease outcomes and survival in colorectal cancer patients. Since previous research on the role of diet for colorectal cancer survivors is limited, the study may be of great importance for this cancer population.

    5, 10 and 15 years

  • Overall survival

    Overall survival (OS) (event is defined as death from any cause)

    5, 10 and 15 years

Secondary Outcomes (16)

  • Time to recurrence

    up to 15 years

  • CVD -free survival

    up to 15 years

  • CRC-specific survival

    up to 15 years

  • Total cancer-specific survival

    up to 15 years

  • Inflammatory disease-specific survival

    up to 15 years

  • +11 more secondary outcomes

Study Arms (2)

Intervention group

EXPERIMENTAL

The intervention group (n = 250) receives an intensive dietary intervention lasting for 12 months and a subsequent maintenance intervention for 14 years. Both groups are offered equal general advice of physical activity.

Other: Norwegian food based dietary guidelines

Control group

OTHER

The control group (n = 250) receives no dietary intervention other than standard clinical care. Both groups are offered equal general advice of physical activity.

Other: Norwegian food based dietary guidelines

Interventions

several means will be applied to guide participarts to cohere to the dietary guidelines including access to clinical nutritionists, free food, food discounts, cooking courses, cookbook/recipies, study website, organized physical activity, etc
