Clinical Trial Summary

A multicentre, prospective randomized, active-controlled feasibility trial of volatile-based anaesthesia vs. propofol-based total intravenous anaesthesia to investigate the impact of anaesthesia on long-term (i.e. 5-years) patient cancer outcomes in patients undergoing elective major cancer surgery.

Description:

This study aims to assess the feasibility of conducting a phase IV, multi-centre, single-blinded, randomized control trial (VAPOR-C (Main)). Primary aims To measure the ability to recruit eligible patients into the study. To measure the ability to successfully deliver each of the two anaesthetic techniques (volatile-based general anaesthesia and propofol-based anaesthesia) according to the research protocol.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	To measure the ability to recruit eligible patients into the study.	The study protocol will be assessed as feasible if a recruitment rate of at least 75% is achieved.	18 months
Primary	To measure the ability to successfully deliver each of the two anaesthetic techniques (volatile-based general anaesthesia and propofol-based anaesthesia) according to the research protocol.	The study protocol will be assessed as feasible if a successful delivery rate of at least 90% is achieved.	18 months
Secondary	To identify that all sites can capture data within the electronic case report form (eCRF) and utilize the electronic data capturing system (REDCap).	All missing data to be recorded including reason for missing data, where available. Quantitative and qualitative analysis of reasons for missing data will be analysed by : Number of fields with missing data (percentage) and reason for missing data ( qualitative descriptor). Fields with >1 missing data point will be analysed for reasons for failure.	18 months
Secondary	To test the efficiency of the centralized patient enrolment and computer randomization system.	Number of events of failed randomisation will be recorded on eCRF (under 'treatment of subjects"). Quantitative analysis of failed randomisation (reported as %) as well as descriptive reason for failure will be recorded and analysed. This will allow shortcomings in the use of the computer-generated centralised randomisation program to be identified and ratified.	18 months
