N2, i.e. four or more lymph nodes in the mesorectum showing morphological signs on MRI indicating metastatic disease. Positive MRF, i.e. tumor or lymph node < 1 mm from the mesorectal fascia. Enlarged lateral nodes, > 1 cm (lat LN+)
Primary tumour characteristics: Histological proof of newly diagnosed primary adenocarcinoma of the rectum

Summary

This trial is testing whether giving chemotherapy before surgery, instead of after, will improve survival rates for people with locally advanced rectal cancer.

Who is the study for?
This trial is for adults with newly diagnosed, high-risk rectal cancer that hasn't spread to distant parts of the body. Eligible patients must have certain tumor characteristics on MRI and can't be pregnant or breastfeeding, have uncontrolled medical conditions, significant heart disease, neuropathy symptoms, known malabsorption syndromes, or a history of other cancers within the last 5 years.
What is being tested?
The RAPIDO Trial is testing a new treatment approach against standard care in rectal cancer. Patients will either receive short-course radiotherapy followed by chemotherapy before surgery (M1 scheme) or the usual long course chemoradiotherapy before surgery. The goal is to improve survival rates by treating both local tumors and potential micro-metastases early.
What are the potential side effects?
Potential side effects include those common to radiation therapy such as skin irritation and fatigue; chemotherapy-related issues like nausea, vomiting, hair loss; surgical complications; and possibly increased risk of infections due to weakened immune response.
