A groundbreaking robotic-assisted bronchoscope is transforming the way physicians detect and diagnose lung cancer, particularly tumors located in hard-to-reach areas of the lungs. Recent results from a gold-standard randomized controlled trial, presented at the European Respiratory Society (ERS) Congress in Amsterdam, highlight the system’s remarkable accuracy in accessing small peripheral lung tumors that traditional bronchoscopes struggle to reach.
Unlike conventional techniques, the robotic bronchoscope integrates advanced navigation technology with a specialized CT scanner, enabling doctors to locate tumors buried deep within the lungs. This integration allows clinicians to perform biopsies with unprecedented precision, ensuring that even the earliest cancers can be detected and tested. Early detection is critical in lung cancer management, as patients diagnosed at initial stages have a significantly higher chance of successful treatment and long-term survival.
The study, led by Dr. Thomas Gaisl from University Hospital Zürich, Switzerland, involved a team of researchers including Dr. Carolin Steinack, who presented the findings at the ERS Congress. “This technology is very advanced and expensive, so rigorous testing against conventional methods is essential,” Dr. Gaisl said. “Until now, there has been no direct evidence linking the cost of robotic bronchoscopy to improved clinical outcomes.”

Clinical Trial Demonstrates Remarkable Success
The trial included 78 patients who collectively presented with 127 abnormal growths located at the outer edges of the lungs, regions typically inaccessible via standard bronchoscopes. These tumors were, on average, only 11mm in size, and less than 15% had a connecting airway, making them particularly challenging to biopsy using traditional methods.
Participants were randomly divided into two groups. Half were examined using the robotic-assisted bronchoscope with integrated cone-beam CT (CBCT), while the other half received conventional bronchoscopy guided by standard X-ray imaging. The results were striking. Traditional bronchoscopy successfully accessed and biopsied only 23% of tumors. In contrast, the robotic system enabled doctors to reach and biopsy more than 84% of these challenging lesions.
Furthermore, patients for whom the conventional method failed were subsequently tested with the robotic system. Of these, nearly 93% achieved a successful biopsy, underscoring the robotic platform’s superiority in accessing peripheral lung tumors. Overall, 68 patients were diagnosed with lung cancer, and 50 of these cases represented stage 1A, the earliest form of the disease.
Dr. Steinack explained, “Robotic-assisted bronchoscopy with CBCT achieves a diagnostic yield more than three times higher than conventional techniques. In clinical practice, this means we can provide accurate diagnoses for patients who previously had no viable options.”
Expanding Access to Hard-to-Reach Tumors
Although only around 20 robotic bronchoscopy systems are currently in use across Europe, adoption is growing steadily. Dr. Steinack emphasized that the technology enables specialists to access nearly any region of the lung, significantly expanding the number of patients who can receive timely biopsies. Early detection facilitates treatment when it is most effective, potentially improving patient outcomes and survival rates.
Dr. Gaisl added, “In high-volume centers that frequently treat patients with small, peripheral lung lesions, the benefits of this technology justify the investment. However, it should be reserved for cases where conventional bronchoscopy is not an option, particularly for small, hard-to-reach tumors.”
The cost of the robotic system is approximately €1 million, with each procedure adding around €2,000. While this represents a significant investment, researchers argue that the ability to access and accurately diagnose previously unreachable tumors provides clear clinical advantages.
Future Applications: Diagnosis and Treatment in One Procedure
The research team plans to explore whether the same robotic technology can be adapted for combined diagnosis and treatment in a single session. For instance, after locating a tumor, the system could potentially deliver targeted therapies, such as radiofrequency or microwave ablation, to destroy cancerous tissue. This dual capability could streamline treatment, reduce patient risk, and accelerate recovery.
In a related study also presented at the ERS Congress, Dr. Gaisl’s team compared robotic bronchoscopy with other advanced guidance technologies. These included virtual 3D airway models and electromagnetic navigation bronchoscopy, a GPS-like system for navigating the lungs. The robotic system outperformed both alternatives, confirming its superior precision and effectiveness in diagnosing small, difficult-to-reach tumors.
Expert Perspectives
Professor Aleš Rozman, Chair of the European Respiratory Society’s expert group on interventional pulmonology and Head of the Endoscopy Department at University Clinic Golnik, Slovenia, praised the research: “Lung cancer claims approximately a quarter of a million lives in Europe each year. Survival rates improve dramatically when cancers are diagnosed early, but small tumors are often extremely difficult to detect. This study demonstrates that robot-assisted technology can significantly enhance our ability to diagnose these tiny, hard-to-access tumors. Gold-standard research like this is vital to justify the substantial costs associated with adopting such advanced equipment.”
Implications for Clinical Practice
The results from this trial mark a major advance in lung cancer diagnostics. Robotic bronchoscopy is particularly suited for patients with small, peripheral lesions that evade conventional bronchoscopic access. By combining high-resolution imaging, real-time navigation, and robotic precision, this technology increases the likelihood of successful biopsies and early-stage diagnosis.
Early detection not only improves survival rates but also allows patients to undergo less invasive treatments. Stage 1 lung cancer patients, for instance, may qualify for surgical removal or targeted therapies rather than more aggressive treatments required for advanced-stage disease. As more hospitals adopt robotic systems, the technology could become an essential tool in thoracic oncology, improving outcomes for countless patients.
Challenges and Considerations
Despite its promise, the widespread implementation of robotic bronchoscopy faces several challenges. High costs and the need for specialized training may limit adoption, particularly in smaller hospitals. Moreover, procedural time and logistical considerations must be optimized to ensure that robotic bronchoscopy is both cost-effective and accessible to patients who need it most.
Nonetheless, the clinical benefits are compelling. With diagnostic yields exceeding those of traditional bronchoscopy by more than threefold, robotic systems represent a paradigm shift in the management of early lung cancer. As research continues and technology evolves, the potential to combine diagnosis and treatment in a single robotic procedure may further enhance patient care and streamline lung cancer management.
