NCT05319054

Brief Summary

Currently, no standard exists for the treatment and management of Low Anterior Resection Syndrome (LARS)- a common disorder that affects patients who have had part of their bowel removed due to colorectal cancer. Decisions about which treatment patients receive is at the discretion of local clinicians, leading to a variation in both clinical practice and the outcomes of these patients. As a result, there is a need for research to assess what treatments are most effective in treating or managing LARS to establish a consensus and develop a treatment pathway in the UK. This study aims to assess the feasibility of undertaking such a trial utilising a novel 'trial within cohorts (TWiCs)' study design, with a view to informing the design of a full-scale trial.

Outcome Measures

Primary Outcomes (10)

  • Recruitment rate of to cohort arm of study

    The total number of participants enrolled into the study over the recruitment period.

    9 months

  • Assess characteristics of patients recruited to the cohort

    We will record basic demographics, medical history and prevalence of relative symptoms of participants enrolled in the cohort study to describe the characteristics of no- minor- and major- LARS patients

    9 months

  • Prevalence of 'major LARS' in the patient cohort

    The number of participants in the cohort that meet the criteria for 'major low anterior resection syndrome (LARS)', as measured by the LARS scoring tool. LARS scoring tool produces a score from 0 - 42, which represents the severity of symptoms, where 0 is least severe and 42 is most severe. Score =\>30 is considered 'major LARS'. LARS score will be measured at 5 times at 3-monthly intervals over 12 months.

    12 months

  • Onset of 'major LARS' symptoms in relation to surgery

    The time (in months) from resection surgery to onset of 'major LARS' symptoms, as reported by the LARS scoring tool.

    Time from surgery to onset of major LARS, up to 10 years.

  • Onset of 'major LARS' symptoms in relation to radiotherapy treatment

    The time (in months) from completing radiotherapy treatment to onset of 'major LARS' symptoms, as reported by the LARS scoring tool.

    Time from ending radiotherapy treatment to onset of major LARS, up to 10 years.

  • Recruitment rate to randomised trial part of the study

    The total number of cohort participants that are enrolled into the randomised trial part of the study, over the recruitment period.

    9 months

  • Proportion of randomised participants that are allocated to each trial arm

    The proportion of randomised participants that meet the criteria for, and are allocated to, each of the three trial arms (transanal irrigation; sacral neuromodulation; optimised conservative management).

    9 months

  • Describe variation in clinical practice across UK sites

    Where possible, we will record patient's previous treatments and interactions with health services in relation to their bowel dysfunction symptoms. This will be used to describe the variation in UK clinical practice in terms of diagnosis, management and treatment pathways.

    Up to 10 years prior to recruitment

  • Compliance of participants to the study programme

    The proportion of participants that complete and return follow-up questionnaires (four questionnaires at 3-month intervals).

    12 months

  • Adherence of participants to the treatment programme

    The proportion of patients that continue to receive the treatment assigned to them at the end of the follow-up period.

    12 months

Secondary Outcomes (7)

  • Change in LARS score

    12 months.

  • Change in EuroQuol 5-Dimension Health-related Quality of Life instrument (5-level) (EQ-5D-5L)

Study Arms (4)

Cohort

NO INTERVENTION

Patients who have undergone colonic resection for colorectal cancer in the last 10 years. Patient reported outcome measures collected at 3-monthly intervals.

Optimised Conservative Management

ACTIVE COMPARATOR

Cohort participants who are identified as having 'major LARS' at any point are treated with Optimised Conservative Managements, consisting of medication, dietary advice, lifestyle advice and physiotherapy.

Other: Optimised Conservative Management

Trans-Anal Irrigation

ACTIVE COMPARATOR

Cohort participants who are identified as having 'major LARS' at any point are treated with Trans-anal irrigation, in additional to receiving optimised conservative management. Transanal irrigation system will be decided upon with the participant and procured locally.

Device: Trans-Anal IrrigationOther: Optimised Conservative Management

Sacral NeuroModulation

ACTIVE COMPARATOR

Cohort participants who are identified as having 'major LARS' at any point are treated with Sacral Neuromodulation system, in addition to receiving optimised conservative management. Medtronic Interstim system will be used.

Device: Sacral NeuroModulationOther: Optimised Conservative Management

Interventions

Sacral Neuromodulation group will include up-to 20 patients with major LARS. Medtronic Interstim system will be used, including 2 week trial device.

Sacral NeuroModulation

Trans-Anal irrigation group will include up-to 20 patients with major LARS. Specific system will be agreed with the patient, depending on eligibility and preference.

Trans-Anal Irrigation

Optimised conservative management will include up-to 30 patients with major LARS. They will be provided with a resource booklet which includes dietary and lifestyle advice as well as exercises that can be undertaken independently.
