Trial Summary

What is the purpose of this trial?

During video-assisted thoracoscopic lobectomy (VATS), the surgeon inserts a small camera attached to a thoracoscope that puts the image onto a video screen. Instruments are inserted via small incisions, and the lung resection is completed. 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. The instruments give the surgeons increased range of motion during the surgery, and research demonstrates that RTS has a less steep learning curve as compared to VATS. Both VATS and RTS demonstrated better results as compared to traditional thoracotomy (open surgery). However, Robotic lobectomy has not yet been compared directly to video-assisted thoracoscopic lobectomy (VATS) in a prospective manner. There are two major barriers against the widespread adoption of robotic thoracic surgery. The first barrier is the lack of high-quality prospective data. To our knowledge, there are no prospective trials comparing VATS to RTS for early stage lung cancer. The second major barrier to the widespread adoption of robotic technology in thoracic surgery is the perceived higher cost of Robotic lobectomy. To address these barriers, the investigators will undertake the first randomized controlled trial comparing Thoracoscopic Lobectomy to Robotic Lobectomy for early stage lung cancer. Prospective randomization will eliminate the biases of retrospective data and will serve to determine whether there exist any advantages to Health Related Quality of life (HRQOL) or patient outcomes in favour of Robotic Lobectomy over VATS Lobectomy. Furthermore, through a prospective cost-utility analysis, this trial will provide the highest quality data to evaluate the true economic impact of robotic technology in thoracic surgery in a Canadian health system.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of robotic-assisted thoracic surgery for early-stage lung cancer?

Research shows that robotic-assisted thoracic surgery for early-stage lung cancer is safe and effective, with benefits like less pain after surgery, lower risk of death, and shorter hospital stays compared to video-assisted surgery. It also provides long-term results similar to traditional methods, making it a promising option for patients. ^{1 2 3 4 5}

Is robotic thoracic surgery safe for humans?

Robotic thoracic surgery, including robotic lobectomy, is generally considered safe for humans, with studies showing similar safety outcomes to video-assisted thoracic surgery (VATS). It offers benefits like shorter hospital stays and faster recovery, although its widespread adoption is still debated. ^{3 5 6 7 8}

How does robotic thoracic surgery differ from other treatments for early-stage lung cancer?

Robotic thoracic surgery is a minimally invasive treatment that uses robotic technology to assist surgeons in performing precise operations, potentially improving short-term outcomes and operative safety compared to traditional methods like video-assisted thoracic surgery (VATS) and thoracotomy. This approach may offer better lymph node dissection, which is important for accurate cancer staging and treatment. ^{2 3 9 10 11}

Treatment Details

Interventions

• Robotic thoracic surgery (Procedure)
• Video-assisted thoracoscopic surgery (Procedure)

Trial Overview The study compares two types of minimally invasive lung surgery: video-assisted thoracoscopic lobectomy (VATS) and robotic thoracic surgery (RTS). Patients will be randomly assigned to receive either VATS, which uses a camera and small incisions, or RTS, which employs precise instruments and 3D imaging.

Findings from Research

The RAVAL trial is a large, prospective randomized controlled trial comparing robotic-assisted lobectomy to video-assisted lobectomy in 186 to 592 patients with early-stage non-small cell lung cancer, aiming to provide high-quality data on patient-reported health-related quality of life outcomes.

The trial will also assess cost-effectiveness and 5-year survival rates, addressing key barriers to the adoption of robotic surgery in thoracic procedures, such as perceived higher costs and lack of robust evidence.

RAVAL trial: Protocol of an international, multi-centered, blinded, randomized controlled trial comparing robotic-assisted versus video-assisted lobectomy for early-stage lung cancer. Patel, YS., Hanna, WC., Fahim, C., et al.[2022]

In a comparison of 28 video-assisted thoracoscopic surgery (VATS) lobectomies and 28 robotic lobectomies, both methods showed similar perioperative outcomes, including operative time and length of hospital stay, indicating that robotic surgery is as effective as traditional methods.

The robotic approach demonstrated enhanced safety, with a lower rate of emergency conversions for uncontrolled bleeding (1 in the robotic group vs. 4 in the VATS group), suggesting it may be a safer option for early-stage non-small cell lung cancer surgery.

A meta-analysis of 3379 patients found that robotic thoracic surgery (RTS) and video-assisted thoracic surgery (VATS) have similar rates of perioperative morbidity and mortality, indicating that RTS is a safe alternative to VATS for lung cancer resection.

The study suggests that while RTS shows comparable outcomes to VATS, further randomized studies are needed to explore its potential advantages and disadvantages in specific clinical settings.

Robotic thoracic surgery versus video-assisted thoracic surgery for lung cancer: a meta-analysis. Ye, X., Xie, L., Chen, G., et al.[2022]

In a study of 61 patients with early-stage lung cancer, robot-assisted video-assisted thoracic surgery lobectomy was performed successfully without any emergent conversions to traditional thoracotomy, indicating the procedure's feasibility.

At a mean follow-up of 28 months, all patients were alive with no local recurrence, although 4 patients developed distant metastases, suggesting that while the surgery is effective, further long-term evaluation is needed.
