Tidsramme: From baseline (T0) to the first date of documented progression or date of death from any cause, wichever came first, assesed up to 5 year.
|
Evaluate progression-free survival defined as; the date of randomization to the date of disease progression or death, respectively.
|
From baseline (T0) to the first date of documented progression or date of death from any cause, wichever came first, assesed up to 5 year.
|
|
Overall survival (OS)
Tidsramme: From baseline (T0) on, survival follow-up will be continued after study completion for a maximal of 5 years in accordance with standard-of-care follow-up.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Habitual dietary intake (Food Frequency Questionnaire)
Tidsramme: At baseline (T0) and at 3-4 months (T2)
|
Nutritional intake is measured using a semi-quantitative Food Frequency Questionnaire (FFQ).
Scores are calculated using the Dutch National Food Consumption tables.
The FFQ will be used to evaluate habitual diet and fiber intake.
|
At baseline (T0) and at 3-4 months (T2)
|
|
Physical activity level (Short QUestionnaire to ASsess Health-enhancing physical activity)
Tidsramme: At baseline (T0) and at 3-4 months (T2)
|
Physical activity is measured using the Short QUestionnaire to ASsess Health-enhancing physical activity (SQUASH).
The questions in the SQUASH are pre-structured in commuting, leisure time, household and work/school activities.
Scores will be assigned to the different reported activities base on intensities in MET and translated to minutes of physical activity.
|
At baseline (T0) and at 3-4 months (T2)
|
|
Sleep quality and duration (Pittsburgh Sleep Quality Index)
Tidsramme: At baseline (T0) and at 3-4 months (T2)
|
Sleep quality is measured with the Pittsburgh Sleep Quality Index (PSQI), a 19-item questionnaire with scores ranging from 0-21.
A score above 5 indicates bad sleep quality.
|
At baseline (T0) and at 3-4 months (T2)
|
|
Bristol Stool Scale (BSS)
Tidsramme: Measurement at baseline (T0), 3-4 weeks (T1), 3-4 months (T2), and 6-7 months (T3) after start ICI

|
Circulating tumor DNA (ctDNA)
Tidsramme: Measurement at baseline (T0), 3-4 weeks (T1), 3-4 months (T2), and 6-7 months (T3) after start ICI
|
ctDNA levels will be analysed to evaluate circulating tumor DNA.
|
Measurement at baseline (T0), 3-4 weeks (T1), 3-4 months (T2), and 6-7 months (T3) after start ICI

|
Short-Chain Fatty Acids
Tidsramme: Measurement at baseline (T0), 3-4 weeks (T1), 3-4 months (T2), and 6-7 months (T3) after start ICI
|
Fecal and Plasma SCFA's levels will be evaluated.
