Background and study aims
Bladder cancer is one of the most common forms of cancer. For most patients, the bladder cancer is superficial and can be treated locally in the bladder. However, for about one in five patients, cancer invades the bladder muscle and for these the most common curative treatment is cystectomy. Cystectomy can be performed either as open surgery, with a longer incision in the lower abdomen, or as a robot-assisted laparoscopic procedure. Robot-assisted laparoscopic cystectomy has been developed during the last 15 years and is routinely performed at some centres around the world. However, it is not entirely certain that a laparoscopic cystectomy is as safe as open surgery, or that there are sufficient advantages to offset the higher procedure-related costs. The aim of this study is, therefore, to find out whether robot-assisted laparoscopic cystectomy is oncologically as safe as open cystectomy, whether there is a difference in rates of complications, and if it is cost-effective
Who can participate?
Men and women with urinary bladder cancer planned to undergo cystectomy
What does the study involve?
Participants are randomly allocated to either robot-assisted laparoscopic cystectomy (experimental group) or open cystectomy (control group)
What are the possible benefits and risks of participating?
Robot-assisted laparoscopic cystectomy may lead to less blood loss, faster recovery, and fewer complications than open cystectomy. It is possible, however, that there may be an increased risk of recurrence or progression from bladder cancer
Where is the study run from?
University of Gothenburg/Sahlgrenska University Hospital (Sweden)
When is the study starting and how long is it expected to run for?
September 2019 to September 2028
Who is funding the study?
The study is funded by the Agreement concerning research and education of doctors in Sweden

Scientific title | Robotic-Assisted radical Cystectomy vErsus open Radical cystectomy: a randomised non-inferiority trial comparing 3-year recurrence-free survival in patients undergoing cystectomy for urothelial carcinoma of the bladder |
Study acronym | RACER |
Study objectives | Robot assisted laparoscopic cystectomy is non-inferior to open cystectomy with regards to 3-year progression-free survival |
Ethics approval(s) | Approved 07/01/2019, Swedish Ethical Review Authority (Etikprövningsmyndigheten, Box 2110, 750 02 Uppsala, Sweden; +46-10-4750800), ref: 2019-00717 / 844-18 |
Health condition(s) or problem(s) studied | Bladder cancer |
Intervention | For both the treatment arms, eligible patients will be offered neo-adjuvant or induction chemotherapy. Randomisation to robot assisted or open surgery will be performed after any preoperative chemotherapy has been finished. Randomisation will be performed through an electronic data capture system, with a computer-generated list. Treatment arms will be stratified by participating centre and muscle-invasive or non-muscle-invasive disease. Both arms will undergo surgery with an identical enhanced recovery protocol. Participating subjects will receive either robot assisted laparoscopic cystectomy (experimental arm) or open cystectomy (control arm). The urinary deviation can be performed either entirely intra-corporeally or through a small incision extra-corporeally. The type of deviation is at the discretion of the surgeon and patient. All surgeons participating in the study is mandated to have performed at least 10 cystectomies of the relevant type (open or robotic) in the preceding year. Follow-up will be performed with CT thorax and abdomen, which will be assessed by RECIST criteria, according to the Swedish National Guidelines for urothelial cancer. This follow-up scheme is dependent on the final pathology report, and may be subject to change according to updates in the National Guidelines. |

Primary outcome measure | Progression-free survival at three years following cystectomy |
Secondary outcome measures | Surgical outcomes: 1. Rate of complications 2. Blood loss 3. Rate of transfusion 4. Time of stay Long-term outcomes: 5. Rate of unplanned readmission 6. Quality of life measured by questionnaires FACT-G/Bl-Cys and WHODAS2.0 at baseline, and 3, 6 and 12 months and EQ-5D-5L at baseline and weekly for the first 4 postoperative weeks 7. Total health-care related costs following cystectomy, calculated for the direct and indirect costs related to the surgery for the first 6 months |
