Rectal Cancer Neoadjuvant Therapy-Real World Study (RC-NAT-RWS)
27. april 2026 oppdatert av: Yao Hongwei, Beijing Friendship Hospital
Establishing a Strategy for Selecting Watchful Waiting and Determining the Optimal Timing for Surgery Following Neoadjuvant Therapy
This study aims to utilise a real-world data platform to integrate multi-omics data-including radiomics, gut microbiota, pathological quality control and liquid biopsy-to construct a multidimensional predictive model for the efficacy of rectal cancer treatment following neoadjuvant therapy.
By integrating multimodal data, the study aims to accurately assess the efficacy of neoadjuvant therapy and identify patients suitable for a 'watch-and-wait' strategy, thereby achieving tumour control and preserving organ function without the need for surgery.
Furthermore, it seeks to provide scientific evidence for the efficacy of the 'watch-and-wait' strategy and the selection of optimal timing for surgery, whilst validating the model's effectiveness and assessing its clinical feasibility through prospective clinical trials.

Detaljert beskrivelse
- Optimisation and predictive modelling of immunotherapy combined with neoadjuvant chemoradiotherapy Through real-world studies, we will evaluate the efficacy and safety of immunotherapy combined with neoadjuvant chemoradiotherapy in patients with locally advanced rectal cancer, focusing on comparing outcomes with traditional chemoradiotherapy regimens to optimise neoadjuvant treatment protocols. By integrating radiomics and molecular subtyping data, we will develop a deep learning model to predict the rate of pathological complete response, thereby accurately forecasting treatment outcomes for patients. This model can further optimise personalised treatment decisions, enhance the effectiveness of organ-preservation strategies, and ultimately reduce surgical trauma for patients.
- A Treatment Efficacy Assessment System Combining Multi-omics Data with Artificial Intelligence Integrate multi-omics data (such as molecular subtyping, radiomics, and pathological assessment) with artificial intelligence technology to establish a treatment efficacy assessment system. Utilise deep learning models to analyse pre- and post-treatment imaging data and pathological samples, thereby achieving precise efficacy assessment.

Neoadjuvant Therapy Cohort for Rectal Cancer
This study is a multicentre, real-world evidence (RWE) study designed to evaluate clinical treatment regimens that offer greater benefits to patients.
It will provide evidence-based guidance for clinicians in China regarding the selection of comprehensive treatment regimens for patients with advanced rectal cancer, thereby further refining and optimising clinical practice guidelines for the diagnosis and treatment of rectal cancer; it will also explore new treatment strategies for patients with locally advanced rectal cancer in the era of immunotherapy.
Study design: A combination of prospective observational and retrospective cohort studies.
The primary endpoint is the complete response rate (pathological complete response and clinical complete response).

Overall Survival (OS)
Tidsramme: within 5 years after completion of neoadjuvant therapy
|
Overall Survival (OS) is the primary and most objective endpoint in oncology clinical trials.
It measures the time from a defined starting point (e.g., date of diagnosis, randomization in a trial, or start of treatment) until death from any cause.
