Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Trial is evaluating Robotic surgery for resection of their early-stage lung cancer. Surgery will be performed by a qualified thoracic surgeon and the surgery will take up to 3 hours. This is a standard of care treatment of lung cancer currently via keyhole surgery where the surgeon operates the instruments robotically. The trial will be evaluating the short-term outcomes post-surgery (compared to VATS [Video-Assisted Thoracic Surgery] resection) such as length of surgery, complications, length of post operative hospitalisation, and will also evaluate quality of life post-surgery.

Treatment: Surgery
Comparator / control treatment
Trial is evaluating standard video-assisted thoracoscopic surgery for resection of their early-stage lung cancer. This is a standard of care treatment of lung cancer currently via keyhole surgery where the surgeon operates the instruments manually. The surgery typically takes up to 3 hours and will be performed by a specialist thoracic surgeon. The trial will be evaluating the short-term outcomes post-surgery (compared to robotic resection) such as length of surgery, complications, length of post operative hospitalisation, and will also evaluate quality of life post-surgery.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be stratified by surgeon. To ensure balance within local data and international data, there will also be stratification by procedure extent, viz. lobectomy or segmentectomy. Participants will be randomised using a web-based Research Electronic Data Capture (REDCap).

Statistical methods / analysis
Baseline characteristics of both treatment groups will be compared to ensure homogeneity in the patient population. Descriptive statistics will be reported by treatment group where categorical variables will be reported as counts (percentages) and continuous variables as mean (standard deviation) or as median (25th percentile, 75th percentile). All analyses of primary and secondary outcomes will be carried out based on the intention-to-treat principle. Unadjusted comparisons of continuous outcome measures will be carried out using an independent t-test or the Wilcoxon rank-sum test if the assumptions of the t-test were violated. Unadjusted comparisons of categorical outcome measures will be computed using the chi-squared test, or the Fisher’s exact test if any of the expected values in the contingency table is less than 5, or McNemar’s test. For adjusted analyses multivariable logistic regression analyses will be used for binary outcomes and multivariable linear regression for continuous outcomes. The results of comparisons between groups will be presented as mean differences for continuous outcomes and relative risks or odds ratios for binary outcomes, with corresponding 95% confidence intervals and associated p-values.
Survival will be compared using the Kaplan-Meier method and cox proportional hazard models. Survival curves will be compared using the Log-rank test. P-values will be reported to three decimal places with p-values less than 0.001 reported as p < 0.001. All international analyses will be performed using SAS. Table 2 provides a summary of the variables, measures and methods of analysis. Local analyses will be performed using the R statistical package.

Summary
Brief summary
This trial aims to determine if there is any difference in patient-reported health-related quality of life and other clinical outcomes for patients with early-stage non-small cell lung cancer (NSCLC) who will undergo surgical removal of their cancer by either robotic keyhole surgery (RTS) or video assisted keyhole surgery (VATS).

Who is it for?
You may be eligible for this study if you are aged 18 years or older, you have been diagnosed with early-stage non-small cell lung cancer and you are able to undergo minimally invasive keyhole surgery for removal of your cancer. Your treating doctor will be able to review your lung images to determine whether this type of surgery is right for you.

Study details
Participants who choose to enrol in this study will be randomly allocated by chance (similar to flipping a coin) to undergo surgery by one of two methods. Participants allocated to the first group will undergo robotic-assisted keyhole surgery, it is anticipated this procedure take up to 3 hours. Robotic thoracic surgery (RTS) uses a similar minimally invasive approach, but the very precise instruments involved with RTS allow the surgeon to view the lung using 3-dimensional imaging.
Participants allocated to the second group will undergo video-assisted keyhole surgery, it is anticipated that this procedure will take up to 3 hours. During video-assisted keyhole surgery (VATS), the surgeon inserts a small camera into the lung that puts the image onto a video screen. Instruments are inserted via small incisions, and the lung resection is completed.

Both types of surgery are currently standard of care to successfully remove lung cancer. It is expected that participants in both groups will need to stay in hospital after their surgery to ensure there are no unexpected complications. If you choose to participate in this study, the research team will ask to review your medical records prior to the surgery and for up to 5 years after the surgery to follow your progress.

It is hoped this research will demonstrate any differences in patient outcomes following each type of surgery. If one surgical method is found to be more effective for removal of cancer and less painful for patients, the evidence gathered from this trial may be used to promote use of that surgical method for future cancer patients.
