Prevalence of Sleep Apnea in Patients Undergoing Surgery for Colorectal Cancer
Sweden212 participantsStarted 2015-01-07
Plain-language summary
212 patients with colorectal cancer will be investigated before surgery and 100 of them after surgery. 597 individuals from a previous population based study will serve as controls to the prevalence of sleep apnea in the general population.
Investigations will include polysomonographic sleep apnea recordings during one night, lung function measurements, blood gas samples and questionnaires.
Controls: Men and women from two population-based cohort studies

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.
1This trial was studying how common sleep apnea is in people having surgery for colorectal cancer — should I be screened for sleep apnea before my own surgery, and could undiagnosed sleep apnea affect my surgical risks or recovery?
2Since the trial also looked at hypoxia, which means low oxygen levels, is there a connection between sleep apnea and oxygen problems during or after colorectal cancer surgery that I should be aware of in my case?
3This study has already been completed — are there published results that you've seen, and do those findings change how you would approach my pre-surgical evaluation?
4Given that this was an observational study measuring prevalence rather than testing a treatment, are there any next steps or follow-on trials that actually test ways to manage sleep apnea in colorectal cancer patients that might be relevant for me?
5If I do have sleep apnea that hasn't been diagnosed yet, how might that affect decisions about my anesthesia or post-operative monitoring during colorectal cancer surgery?

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.
