About this trial

The aim of this randomized controlled trial is to investigate the feasibility of increasing preoperative dietary fiber intake in individuals with colorectal cancer who will undergo surgery. This will be done using 1) digital personalized dietary advice or 2) a dried vegetable product compared to 3) habitual diet (control).

Trial outcomes

Primary outcomes

1

Dietary fiber intake

Change in dietary fiber intake is assessed via two 24hr dietary recalls.

Time frame
3 time points: T0 (at baseline), T1 (after 2 weeks of intervention), and T2 (at the end of intervention period, on average after 4 weeks).

Secondary outcomes

1

Stool pattern

Change in stool frequency per week and average stool consistency per week assessed using the Bristol Stool Chart.

Time frame
3 time points: T0 (at baseline), T1 (after 2 weeks of intervention), and T2 (at the end of intervention period, on average after 4 weeks).
2

Gastrointestinal symptoms

Change in gastrointestinal symptoms measured with the Gastrointestinal Symptom Rating Scale (GSRS). Higher scores mean a worse outcome.

Time frame
3 time points: T0 (at baseline), T1 (after 2 weeks of intervention), and T2 (at the end of intervention period, on average after 4 weeks).
3

Health-related quality of life

Change in quality of life measured with the European Organization for Research and Treatment for Cancer Quality of Life Questionnaire (EORTC QLQ-C30 \& CR29). Global and functional health-related quality of life will be calculated, for which higher scores indicate better quality of life. Also symptom scales will be calculated, for which higher scores indicate higher presence or severity of a symptom.

Time frame
3 time points: T0 (at baseline), T1 (after 2 weeks of intervention), and T2 (at the end of intervention period, on average after 4 weeks).
4

Fecal gut microbiota composition

Measured using 16S rRNA amplicon sequencing in fecal samples.

Time frame
3 time points: T0 (at baseline), T1 (after 2 weeks of intervention), and T2 (at the end of intervention period, on average after 4 weeks).
