5. Study Description

Brief Summary
This study is designed to explore the hypothesis that in patients with a Locally advanced rectal cancer (LARC) treated with a Total neoadjuvant therapy (TNT) strategy based on short course radiotherapy (5x5Gy) followed by neoadjuvant consolidation chemotherapy is associated with a higher rate of pathological clinical response and sustained (>1year) complete clinical response when compared to an historical cohort treated with long course chemoradiation therapy (CRT), total mesorectal excision (TME) and adjuvant chemotherapy (ACT).
Detailed Description
Non-operative management with a Watch and Wait (W&W) strategy has been advocated for selected patients with a locally advanced rectal cancer (LARC) and a complete clinical response (cCR) after neoajuvant (NA) treatment. In this context, total neoadjuvant therapy (TNT), i.e the use of radiotherapy and full dose of post-operative chemotherapy as part of NA treatment, has emerged as a strategy to enhance treatment response. Currently, TNT has reported higher rates of pCR and organ preservation when compared to current standard of care. However, the best TNT strategy is still unknown. We therefore hypothesize that in LARC patients, the use of a TNT strategy based on short course RT followed by consolidation chemotherapy is associated with a higher rate of pCR and sustained (>1year) cCR when compared to an historic cohort. The main aim of the present proposal is to assess the effects of a standardized TNT model in LARC patients as a strategy for enhanced pCR/sustained cCR. For this purpose, we propose the following experimental model: In primary Aim 1 we will study if the effects of a TNT strategy over patients with a LARC enhance the rate of pCR/sustained cCR by (1) evaluating the compliance and toxicity of a TNT strategy as a proof of concept of its applicability, (2) assessing the rate of cCR at the end of TNT and (3) assessing the rate of pCR in the surgically managed subgroup and sustained cCR (>1year) in the W&W subgroup. Additionally, in primary Aim 2, we will determine if patients with a W&W strategy have better functional outcomes and quality of life (QoL) than patients treated with TME after TNT by (1) using validated questionnaires for the evaluation of bowel, sexual and urinary function for W&W and TME patients and (2) by evaluating the QoL using a widely-used standardized questionnaire.
