Plain English Summary
Background and study aims
This study is an investigation into the medical outcomes of patients with rectal cancer who underwent a surgical procedure called "Total Mesorectal Excision" (TME) with the assistance of robotic technology. Instead of studying patients in real-time, we're taking a look back in time to analyse data from multiple medical centers where this robotic surgical technique was used.
The primary goal of our research is to determine whether the use of robots in TME surgery has a positive impact on the long-term health and recovery of patients with rectal cancer. We aim to collect and analyse data, comparing the outcomes of patients who had robot-assisted TME surgery with those who underwent traditional procedures.
Who can participate?
Patients aged 18 years or older who underwent rectal cancer surgery beginning in 2014.
What does the study involve?
We aim to combine retrospective data from 3 European datasets (for an estimated total of 3,000 inclusions) to perform high-quality statistical analyses on surgical outcomes (such as length of stay, operative time, and conversion) between laparoscopic and robotic proctectomy with partial or complete TME surgery. We will only be collecting data on patients treated after 2014 in all centres. The study will also have secondary objectives, such as complications, reinterventions and readmissions, pathological outcomes, stoma formation and reversal, and short- and long-term oncological outcomes (local recurrence, distant recurrence, disease-free survival, and overall survival).
What are the possible benefits and risks of participating?
None
Where is the study run from?
Portsmouth Hospitals NHS Trust (UK)
When is the study starting and how long is it expected to run for?
June 2023 to June 2025

| Study hypothesis | Current study hypothesis as of 05/02/2025: This study is a retrospective, multi-centre data study analysing the oncological outcomes in rectal cancer patients that underwent robotic "Total Mesorectal Excision" (TME) surgery. We aim to combine retrospective data from 3 European datasets (for an estimated total of 3,000 inclusions) to perform high quality statistical analyses on surgical outcomes (such as length of stay, operative time, and conversion) between laparoscopic and robotic proctectomy. _____ Previous study hypothesis: This study is a retrospective, multi-centre data study analysing the oncological outcomes in rectal cancer patients that underwent robotic "Total Mesorectal Excision" (TME) surgery.

| Intervention | Current interventions as of 05/02/2025: This is a multicentre, retrospective cohort study for comparative analysis of postoperative surgical outcomes and short- and long-term oncological outcomes after rectal cancer surgery using propensity score-matched cohorts. The study is looking to include all eligible patients treated after 2014 whose data is available at one of the three participating sites and estimates an inclusion of 3000 patients in total. All data transfer will comply with local and UK privacy laws, and have been outlined in a "Data Sharing Agreement" and "Data Management Plan". After reception at the Sponsor site, data will be checked for errors and converted to a file suitable for statistical analysis. This process has been outlined in detail in the "Data Management Plan" as well. This study will not have any influence on the care or lives of patients included in the study. There is no direct benefit and no additional risk for included patients. A patient is eligible for inclusion when they meet all the inclusion criteria and none of the exclusion criteria for the study, as outlined in the protocol. _____ Previous interventions: This is a multicentre, retrospective cohort study for comparative analysis of postoperative surgical outcomes and short- and long-term oncological outcomes after rectal cancer surgery using propensity score-matched cohorts.

| Intervention type | Procedure/Surgery |
| Primary outcome measure | The primary outcome variables will be measured using data held in pre-existing databases at each of the participating sites from rectal cancer patients who underwent robotic total mesorectal excision (TME) surgery at one timepoint: 1. Length of stay in days after surgery 2. Operative time in minutes 3. Blood loss in millilitres |
| Secondary outcome measures | The secondary outcome variables will be measured using data held in pre-existing databases at each of the participating sites from rectal cancer patients who underwent robotic total mesorectal excision (TME) surgery at one timepoint: 1. Intraoperative and postoperative complications recorded as timepoint, type of complication, and Clavien-Dindo classification grading of complication 2. Reinterventions and readmissions after surgery recorded as yes/no and timepoint 3. Pathological outcomes recorded as the number of positive lymph nodes, differentiation grading, quality of the specimen, and positivity of circumferential resection margins 4. Stoma formation as yes/no and type, as well as reversal of stoma and timepoint of reversal 5. Local recurrence of disease as yes/no and timepoint 6. Distant recurrence of disease as yes/no, timepoint, and location of recurrence 7. Disease-free survival as yes/no and timepoint 8. Overall survival as yes/no and timepoint |
