Plain-language summary
This study is a single-center, prospective, randomized, double-arm, Phase II clinical trial designed to evaluate the efficacy of radiotherapy combined with CAPOX, and Iparomlimab and Tuvonralimab (QL1706) as neoadjuvant therapy for locally advanced rectal cancer. Additionally, the study seeks to explore the relationship between biomarkers in blood and tumor tissue and treatment efficacy.
Eligible participants (locally advanced rectal cancer) were randomly assigned in a 1:1 ratio to two groups.
Participants will:
Group A patients received radiotherapy, chemotherapy, and immunotherapy. During the first week of radiotherapy, they received one cycle of CAPOX concurrent chemoradiotherapy. Two weeks after the completion of radiotherapy, they continued with four cycles of CAPOX combined with QL1706 immunotherapy.
Group B patients received radiotherapy and chemotherapy. After completing the concurrent radiotherapy and chemotherapy, they rested for 2-3 weeks before completing 3 cycles of CAPOX consolidation chemotherapy.
Two to three weeks after the completion of neoadjuvant therapy in groups A and B, the efficacy was evaluated, and a decision was made on whether to proceed with surgery or watchful waiting based on the efficacy.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
