Study information
| Study design | Randomised, active controlled, parallel group trial |
|---|---|
| Primary study design | Interventional |
| Secondary study design | Randomised controlled trial |
| Study setting(s) | Hospital |
| Study type | Prevention |
| Scientific title | |
| Study acronym | RELAPS: REcurrent LAryngeal carcinoma PET Study |
| Study objectives | Not provided at time of registration |
| Ethics approval(s) | Ethics approval received from the local medical ethics committee |
| Health condition(s) or problem(s) studied | Laryngeal carcinoma |
| Intervention | Selection for direct laryngoscopy with fluorodeoxyglucose-positron emission tomography (FDG-PET). Two strategy arms are compared: 1. Conventional strategy: direct laryngoscopy under general anaesthesia with taking of biopsies 2. PET based strategy: only direct laryngoscopy under general anaesthesia with taking of biopsies if FDG-PET is positive or equivocal |
| Intervention type | Drug |
| Pharmaceutical study type(s) | |
| Phase | Not Specified |
| Drug / device / biological / vaccine name(s) | Fluorodeoxyglucose |
| Primary outcome measure | Number of direct laryngoscopies (on a group level) needed to detect (a single) recurrent laryngeal carcinoma. |
| Secondary outcome measures | Key: 1. Costs 2. Operability of a recurrence 3. Surgical margins of the salvage laryngectomy 4. Quality of life |
| Overall study start date | 01/02/2005 |
| Completion date | 30/06/2007 |
