Scientific title
RObotic versus LAparoscopic Resection for Rectal cancer: an international, multicentre, prospective, randomised, controlled, unblinded, parallel-group trial of robotic assisted versus laparoscopic surgery for the curative treatment of rectal cancer
Acronym
ROLARR
Study hypothesis
The current proposal aims to test the hypothesis that robotic-assistance facilitates laparoscopic rectal cancer surgery. On short-term follow-up this should result in a reduction in the conversion rate and no worsening of the circumferential resection margin (CRM) positivity rate. On longer-term follow-up, the increased accuracy should improve post-operative bladder and sexual function, enhance quality of life (QoL), and ensure there is no increase in local disease recurrence.

Condition
Rectal cancer, laparoscopic and robotic assisted laparoscopic surgery
Intervention
A total of 400 patients (200 in each arm) will be recruited into the trial over an 18-month period. It is anticipated that approximately 15 patients per month will be recruited in the first 6 months, with monthly recruitment increasing to approximately 25 patients in the final 12 months. Patients will be randomised on a 1:1 basis to receive either robotic-assisted or standard laparoscopic rectal cancer surgery and will be allocated a unique trial number. Laparoscopic mesorectal resection will be performed in accordance with each surgeons usual practice. Robotic-assisted laparoscopic surgery may involve either a totally robotic or a hybrid approach; the only absolute requirement being that the robot is used for mesorectal resection. For the purposes of ROLARR, a totally robotic and a hybrid operation are defined as follows:
1. A totally robotic operation involves a resection of the entire surgical specimen with the use of robotic-assistance.
2. A hybrid operation involves the use of laparoscopic techniques to mobilise the proximal colon with robotic-assistance employed to perform the rectal mesorectal dissection.

Primary outcome measure
Rate of conversion to open surgery as an indicator of surgical technical difficulty.
Conversion is defined as the use of a laparotomy wound for any part of the mesorectal dissection. The use of a limited laparotomy wound to facilitate a low stapled anastomosis and/or specimen extraction is permissible and not defined as an open conversion.
Secondary outcome measures
Current information as of 15/09/2010:
1. Accuracy of surgery (oncological efficacy)
1.1. Pathological CRM positivity rates as recorded from local histopathology review, where resection margin positivity is defined as a distance of ≤1mm of the cancer from any resection margin.
1.2. 3-year local recurrence rates as calculated from the cumulative incidence function plot of time to local recurrence, where time to local recurrence is defined as the time from date of randomisation to date of local recurrence. Local recurrence is defined as evidence of locoregional disease within the surgical field.
2. Intra-operative and post-operative (30 day and 6 month) complications and 30-day operative mortality. Thirty-day operative mortality is defined as deaths occurring from any cause during the first 30 post-operative days
3. Patient self-reported bladder and sexual function as assessed by the International Prostate Symptom Score (IPSS) for male and female bladder function, and the International Index of Erectile Function (IIEF) and Female Sexual Function Index (FSFI) for sexual function
4. Patient self-reported generic health related QoL as assessed by the SF-36 v2.0 and fatigue assessed by the Multidimensional Fatigue Inventory (MFI-20)
5. Three-year disease-free and overall survival. Overall survival is defined as the time from date of randomisation to date of death from any cause. Disease-free survival is defined according to Punt et als definitions as the time from date of randomisation to date of death from any cause, recurrent disease (locoregional or distant recurrence) or second primary cancer (the date of recurrence/secondary cancer is defined as the date of the relevant (e.g. clinical or radiological) assessment which detects the recurrence/secondary cancer).
6. Health economics:
6.1. Preference based QoL measured by EQ-5D and used to calculate quality-adjusted life-years (QALYs)
6.2. Direct resource utilisation
6.3. Cost-effectiveness estimated using QoL and direct resource use information combined with apportioned cost scenarios of the robotic device
6.4. Intra-operative laparoscopic skills (randomly selected cases only) as assessed by an independent expert blind to surgeon and surgery performed using the global assessment tool for evaluation of intra-operative laparoscopic skills 'GOALS'
6.5. Quality of the plane of surgery as assessed by local histopathology review as detailed in Appendix 1 of the protocol
