About this study
Official title: Comparing Outcomes for Minimally Invasive Techniques for Anatomic Lung Resection for Cancer - A Prospective, Comparative, Non-randomized, Open Label Post-market Observational Cohort Study Within Europe
To compare outcomes of minimally invasive surgical techniques for the treatment of early-stage non-small cell lung cancer.
Read the detailed description
Detection of lung cancer is occurring at increasingly earlier stages due to improved screening and the discovery of incidental nodules. Coinciding with this trend is recent data from two international randomized, control trials, RAVAL - (Robotic Lobectomy vs. Thoracoscopic Lobectomy for Early Stage Lung Cancer) and, JCOG0802 (The Japan Clinical Oncology Group) that show oncologic outcomes from segmentectomy are equivalent to lobectomy for cancers ≤2 cm. However, segmentectomy is a more complex technical operation that may not be easily feasible using video assisted thoracic surgery (VATS) but could be facilitated by robotic-assisted thoracic surgery (RATS), allowing improved vision, precision and controlled anatomic dissection.
The LARCS study is designed to understand the perioperative outcomes of patients and identify the real-world selection process of either VATS and RATS segmentectomy and lobectomy for lung cancers ≤2 cm. It aims to generate evidence to support integration of patient-centered care using minimally invasive technology.
In addition, health related quality of life captured in the study will also provide valuable insight into time to recovery, determining burden of the disease, and guide future treatment strategy.

What is being measured
The primary outcome is the main question the study is designed to answer.
Patient reported Quality of Life 1
EQ 5D 5L (European Quality of Life Five Dimension) The EQ-5D-5L is a validated and established generic Patient Reported Outcome (PRO) instrument that uses 6 questions to assess patients' quality of life. It includes a vertical EQ visual analog scale (EQ VAS, 0-100 points) and a descriptive EQ-5D-5L system. An algorithm is used to calculate the scores.
For the descriptive section of the scale, an index value of 1 represents the best possible health state, while an index value of <0 (variable) represents the worst possible health state.
The EQ VAS score is rated on a scale of 0-100 points. 0 points correspond to the worst possible health status, while 100 points correspond to the best possible health status.
Measured: 1 month post surgery
Patient reported Quality of Life 2
RNLI (Reintegration to Normal Living Index) The RNLI has 11 questions and is scored on a visual analogue scale (VAS). On one end: "does not describe my situation" (1 or minimal integration) and "fully describes my situation" (10 or complete integration). Individual item scores are summed to provide the total score. The higher the score, the better the patients perceived integration.
Measured: 1 month post surgery
Secondary outcomes (1)
Number of conversions from pre-operative surgical plan
Number of participants who undergo conversion surgery from the pre-operative surgical plan captured on the surgical decision making form. Conversion may be from segmentectomy to lobetomy, RATS or VATS to open surgery.
Measured: immediately post operative

Questions about this trial
What is this clinical trial studying?
An observational study of Lung Cancer, run by Intuitive Surgical at 13 sites in 7 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 14 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 13 sites in United Kingdom, France, Germany, Denmark, Italy and 2 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Marie Allouis (+33786480495, Marie.Allouis@intusurg.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Patient reported Quality of Life 1 (time frame: 1 month post surgery). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06038227, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Sep 2026; AzTrials last refreshed its copy on 26 Oct 2026.
