Design outcomes

Primary

MeasureTime frame
To determine the three-year organ preservation rates achieved using the standard neoadjuvant approaches in locally advanced rectal cancer.Timepoint: Three year rate

Secondary

MeasureTime frame
To determine the feasibility and tolerability of delivering a brachytherapy boost in patients desiring organ preservation for low rectal cancer.Timepoint: Two years;To measure and compare the gross tumour volumes during radiotherapy planning based on various imaging modalities.Timepoint: Three years;To determine the dosimetry, internal target volume, set up errors and nodal response rates of patients with extra-mesorectal nodes treated with nodal boost, along with quality of life QOL and acute toxicity.Timepoint: three years;To assess the toxicity and QOL of patients achieving complete response and on wait-and-watch protocol.Timepoint: Three years;To measure the local control, disease-free survival and overall survival and compare the outcome of those with and without organ preservation.Timepoint: 5 years;To explore patients and oncologists perspectives on organ preservation in low rectal cancer.Timepoint: One year
