Scientific titleTransanal endoscopic microsurgery (TEM) and Radiotherapy in Early rectal Cancer: a randomised phase II feasibility study
Study acronymTREC
Study objectivesTREC will determine the feasibility of performing a randomised controlled trial (RCT) of radical total mesorectal excision (TME) surgery (current gold standard) versus short course pre-operative radiotherapy (SCPRT) and delayed local excision at 8 - 10 weeks for T1-2N0M0 rectal cancer defined according to both magnetic resonance imaging (MRI) and endorectal ultrasound (ERUS).
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedEarly rectal cancer
InterventionA phase II open, multi-centre randomised controlled trial for patients with early rectal cancer comparing:
1. Conventional TME surgery
2. Short course pre-operative radiotherapy (SCPRT) and delayed local excision with TEM (after an 8 - 10 week interval)
Intervention typeOther
Primary outcome measure(s)

Recruitment, measured at 12, 18 and 24 months

Key secondary outcome measure(s)

1. Safety:
1.1. 30-day mortality
1.2. 6-month mortality
1.3. Surgical morbidity
1.4. Bowel, bladder and sexual function (measured by European Organization for Research and Treatment of Cancer Quality of Life Questionnaires [EORTC QLQ] C29 and C30)
2. Efficacy:
2.1. Histopathological assessment of tumour down-staging according to depth of tumour invasion and the incidence of other high-risk features
2.2. Conversion rates from organ conservation to radical surgery
