Economic Evaluation of Robot-assisted Laparoscopic Radical Prostatectomy vs Conventional Laparoscopic Radical Prostatectomy and Open Retropubic Radical Prostatectomy in Prostate Cancer: a Real-life Study Based on the French National Healthcare Data System (SNDS)
- Conditions
- Prostate Cancer
- Registration Number
- NCT04587284
- Lead Sponsor
- University Hospital, Bordeaux
- Brief Summary
This study aims to assess the cost-effectiveness ratio and the clinical benefit (survival, disease recurrence, functional results) of the robot-assisted laparoscopic radical prostatectomy compared with other procedures using real-life data from SNDS. The population of patients who benefited from robot-assisted surgery will be identified in the SNDS through a practices survey, allowing the identification of centres fully converted to robotics.
- Detailed Description
Over the last 15 years, robot-assisted laparoscopic radical prostatectomy surgery has seen a considerable rise in France. To date, it represents the most common surgical technique for radical prostatectomies, compared with standard procedure such as open retropubic radical prostatectomy or laparoscopic radical prostatectomy (8000 procedures/year, 40% of surgeries). In 2016, the French Health Authority (HAS) published a report on the robot-assisted laparoscopic radical prostatectomy practice that highlighted the small amount of available convincing data to provide evidence for a significant clinical benefit. There were no published data on overall or progression-free survival compared with other surgical procedures, with an important organizational and financial impact for healthcare institutions and patients. The question of the clinical benefit and the cost-effectiveness ratio of this surgical procedure is still relevant taking into account that randomized studies are difficult to carry out and that results of prospective registers will be available in many years. In this context, the use of the French National Claims Database (SNDS) appears to be the best short-term and reduced-cost solution to identify patients who benefited from the three surgical procedures since the rise of robotics. It would provide real-life data to national institutions in order to conclude on the opportunity to set a specific hospital tariff for the robot-assisted laparoscopic radical prostatectomy. This study aims to assess the cost-effectiveness ratio and the clinical benefit (survival, disease recurrence, functional results) of the robot-assisted laparoscopic radical prostatectomy compared with other procedures using real-life data from SNDS. The population of patients who benefited from robot-assisted surgery will be identified in the SNDS through a practices survey, allowing the identification of centres fully converted to robotics.
Recruitment & Eligibility

- Male
- Target Recruitment
- 84667
Total retro-pubic prostatectomy (PTRP) identified in the SNDS by the standard, Classification of Medical Acts "JGFA006" act
- Laparoscopic total prostatectomy (PTL) identified in the SNDS by the CCAM "JGFC001" act and the health and social establishment files number of centers not equipped with a surgical robot
- Robot-assisted total prostatectomy (PTRA) identified in the SNDS by the CCAM "JGFC001" act and the health and social establishment files number of centers equipped with a surgical robot for more than 12 months and having a rate of use of this technique for more than 95% minimally invasive prostatectomies. The number of PTRA will be identified by a survey in each center and the manufacturer's data as explained above
Patient who has not received previous treatment for this cancer by hormone therapy, radiotherapy, brachytherapy or HiFU (treatments sought in the SNDS prior to surgery by the prescription of pharmaceutical specialties or the presence of CCAM procedures)
- Patient operated for laparoscopic radical prostatectomy or robot-assisted laparoscopic radical prostatectomy in a center equipped with a surgical robot but with a rate of use of this technique less than 95% (centers offering different minimally invasive approaches that do not allow to define if the intervention was performed in robotic surgery or in open surgery)
- Patient operated for a robot-assisted laparoscopic radical prostatectomy in a center having started a robotic activity for less than 12 months
Patient previously treated with another therapeutic modality for his prostate cancer (salvage prostatectomies after hormone therapy, radiotherapy, brachytherapy or HiFU)
Study & Design
- Study Type
- OBSERVATIONAL
- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Incremental cost / progression-free (without additional treatment) life-year saved 5 years after initial surgery 5 years after initial surgery Progression-free survival requiring new treatment at 5 years will be calculated from :
* Death within 5 years of surgery
* Occurrence, over the period (5 years), of recurrences / progressions requiring additional treatment by radiotherapy and / or hormone therapy.
A sensitivity analysis will be carried out after 1: 1 matching between subjects in each prostatectomy group.
Estimation of the probability of event-free survival using the Kaplan-Meier estimator; Comparison of the risk of occurrence of each event between groups using a Cox proportional hazards model (after checking the underlying assumptions). The risk comparison will be measured using an hazard ratio, its 95% confidence interval and the p-value associated with the Wald test
* without adjustment, from the overall population;
* after adjustment for the propensity score, from the overall population;
* from matched groups 1: 1.
- Secondary Outcome Measures
Name Time Method Incremental cost / life-year saved at 8 years. 8 years after initial surgery Progression-free survival requiring new treatment at 5 years will be calculated from :
* Death within 8 years of surgery
* Occurrence, over the period (8 years), of recurrences / progressions requiring additional treatment by radiotherapy and / or hormone therapy.
A sensitivity analysis will be carried out after 1: 1 matching between subjects in each prostatectomy group.
