Feasibility Study of Lidocaine Infusion During Bowel Cancer Surgery for Cancer Outcome — FLICOR  

Colorectal Cancer Clinical Trial

Official title: A Randomised Feasibility Study Evaluating the Effect of Perioperative Intravenous Lidocaine on Colorectal Cancer Outcome After Surgery

Status Recruiting

Clinical Trial Summary

This feasibility (small) study aims to see if it is possible to run a large study looking at the effect of lidocaine on large bowel cancer recurrence after surgery in the NHS hospitals.

Clinical Trial Description

Strong preclinical evidence suggests that lidocaine, a type of local anaesthetic commonly used, could potentially reduce cancer recurrence if given during cancer surgery. This study will evaluate the feasibility of conducting a study comparing intravenous lidocaine infusion versus placebo administration for 24 hours from the start of general anaesthesia. The specific population will be any stage 2 or 3 colon or rectal cancer patient undergoing elective laparoscopic colorectal cancer surgery to look at postoperative cancer outcomes in two NHS settings. This study will explore the acceptability, facilitators and potential barriers of recruiting cancer patients, with possible anxieties of a new cancer diagnosis about to have major surgery along with other potential feasibility issues. It will also assess if follow-up and outcome data collection can be streamlined with usual care processes as much as possible and to guide the future definitive trial.

The project will:

1. Perform a feasibility study. This will be similar in design to the future bigger study and will see:

• if there are any problems in giving lidocaine;

• if patients and clinicians would be happy to take part in a study using a design where some patients get the drug and others get a non-active substance (known as placebo);

• how many patients can we get from the different types and stages of bowel cancer;

• if patients can be followed up successfully;

• if we can collect all the data that we would need;

• what measures might work well for the future study;

2. Look to see if blood tests can give some idea on how lidocaine might work in patients and if it can be confirmed in the bigger study.

The study will involve a small number of patients getting either lidocaine or placebo, and:

• filling in questionnaires to measure quality of life;

• follow up phone call at 6 and 12 months after surgery;

• having their records looked at to see if cancer comes back;

• both patients and clinicians to fill in a feedback questionnaire to see how they get on with the study processes;

• having extra blood tests before and after they finish the lidocaine/placebo infusion. ;
