Volatile Anaesthesia and Perioperative Outcomes Related to Cancer Feasibility Study

Peter MacCallum Cancer Centre, Australia169 enrolled

Overview

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.

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.

Outcomes

Primary Outcomes

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.

Time frame: 18 months

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.

Time frame: 18 months

Secondary Outcomes

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.

Time frame: 18 months

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.
