Clinical Trial Summary

IMPROVE-IT2 is a randomized multicenter trial comparing the outcomes of ctDNA guided post-operative surveillance and standard-of-care CT-scan surveillance. The hypothesis of this study is that ctDNA guided post-operative surveillance combining ctDNA and radiological assessments could result in earlier detection of recurrent disease and identify more patients eligible for curative treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	FCI	Fraction of patients with relapse receiving intended curative resection or local treatment aiming at complete tumor destruction as defined at the relevant MDT conference.	5 years
Secondary	3yr-OS	Overall survival at 3 years	3 years
Secondary	5yr-OS	Overall survival at 5 years	5 years
Secondary	TTCR	Time to clinical recurrence	3 years
Secondary	TTMR	Time to molecular recurrence	2 years
Secondary	QoL	Quality of Life by use of EORTC QLQ-C30, version 3.0. The QoL outcome measure is differences in QLQ-C30 score at 12, 24 and 36 months between the experimental and control arm.	3 years
Secondary	FCRI	Fear of Cancer Recurrence Inventory. The FCRI outcome measure is differences in FCRI at 12, 24 and 36 months between the experimental and control arm.	3 years
Secondary	IES-C	Impact of Events Scale Cancer. The IES-C outcome measure is differences in IES-C at 12, 24 and 36 months between the experimental and control arm.	3 years
Secondary	CE	Cost-effectiveness. QoL/Utility weights for the quality-adjusted life years parameter will be QLU-C10D based on EORTC QLQ-C30.	5 years
