Quicksilver II Pilot Study
18 participantsStarted 2026-09
Plain-language summary
This pilot study is being done to answer the following question: Will patients with margin-clear Stage 2 or 3 rectal cancer who don't require a colostomy agree to be randomized to 'surgery only' or 'chemotherapy and then surgery'? Study participants will be randomized to receive either 12 weeks of chemotherapy before rectal cancer surgery or they will proceed directly to surgery. The researchers hypothesize that patients with margin-clear clinical Stage II or III rectal cancer can avoid neo-adjuvant (i.e., pre-operative) radiation and chemotherapy treatments and go directly to surgery. A positive pilot study will support funding requests for a related large efficacy trial; this larger trial, if positive, should lead to an important de-escalation innovation - avoiding use of neo-adjuvant chemoradiation and associated toxicity risks for patients with margin-clear Stage II or III rectal cancer.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* 18+ years of age
* able to provide written consent
* MRI confirmed margin-clear Stage II or III rectal cancer
Exclusion Criteria:
* patients with tumour criteria that encourage neoadjuvant treatments regardless of margin-status (e.g. need for a permanent colostomy, T4 category, and one or more pelvic sidewall lymph nodes with a short axis diameter \>7 mm).
* Unable to provide consent (e.g., language barrier, cognitive issues).
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?
