Revolutionizing skin cancer detection with Vectra 360
The digital age has inaugurated a new tool for dermatologists in France: the Vectra 360 scanner. Residing in Évreux, approximately 100 kilometers from Paris, this imposing device, almost three meters high and five meters wide, captures almost the entire surface of the skin in a single image, thanks to its 92 high-definition lenses. This technological marvel produces detailed skin maps highlighting changes and moles, allowing doctors to zoom in on suspicious areas for further analysis.
Isabelle Lopital, director of France Dermatologie Territoire, at the origin of the project, confirms the effectiveness of the scanner in providing dermatologists with complete skin images facilitating targeted examination of possible skin abnormalities. This major step forward aims to address the considerable delays in scheduling appointments with dermatologists, a pressing problem in various medical sectors due to a shortage of specialist dermatologists.
French Tech tackles melanoma head on
France records around 18,000 new cases of melanoma, the deadliest form of skin cancer, each year, leading to around 2,000 deaths. However, thanks to improvements in early detection and the introduction of innovative treatments, the number of deaths has started to stabilize in recent years.
The country has seen several initiatives aimed at transforming the landscape of early treatment for this dangerous type of cancer. These include a promising solution from French startup Square Mind: an innovative robotic arm that moves gracefully around the patient, capturing high-resolution full-body images in just a few minutes.
At the same time, in Marseille, in the south of the country, the university hospital center was equipped in 2022 with the cutting-edge American Vectra system, at a cost of around 400,000 euros, financed by manufacturers and the Canceropole PACA. Giuliana Monié, dermatologist and head of the Automated Melanoma Diagnostic Center in Marseille, emphasizes the importance of using technology to refine one’s work. The objective is not to replace doctors but to improve their ability to monitor patients, particularly when specialists are scarce.
The next frontier: AI diagnostic assistance
Hope now rests on artificial intelligence (AI) to provide an additional layer of support. With vast data documenting the skin conditions of many people, AI algorithms are being developed to easily and effectively identify emerging or progressive skin diseases across the entire surface of the body.
Monié notes that although machines currently do not have the ability to diagnose autonomously, developments are underway. Ali Khoshlouf, the founder of Square Mind, predicts that within two years, AI could reliably detect melanoma. According to Luc Thomas, skin cancer specialist at Lyon University Hospital, AI could serve as a pre-screening tool, with the human doctor always having the last word in the diagnosis and treatment plan.
Important questions and answers:
1. What is the Vectra 360 scanner?
The Vectra 360 scanner is an advanced device that captures almost the entire surface of the skin with 92 high-definition lenses, creating detailed skin maps to help dermatologists identify skin abnormalities.
2. Why are AI-based diagnostic tools important in French dermatology?
AI innovations, such as AI-based diagnostic assistance, are crucial due to the shortage of specialized dermatologists in France. They help reduce wait times for appointments and can help dermatologists effectively monitor and identify skin conditions.
3. Can AI replace dermatologists in skin cancer diagnosis?
Current technology does not allow AI to completely replace dermatologists. While AI is being developed to support melanoma detection, the human doctor is ultimately responsible for the final diagnosis and treatment decisions.
Main challenges and controversies:
One of the main challenges lies in the balance between integrating AI into dermatological diagnostics and ensuring the accuracy and reliability of diagnoses. The possibility that AI will miss complex cases or rare pathologies that a human specialist could detect remains a concern. Ensuring proper oversight and establishing guidelines for safety and ethics in AI development is crucial.
Controversies could revolve around patient privacy and safety, as these AI systems require large datasets of skin images. There is also debate about the potential devaluation of human expertise and the risk of over-reliance on technology in medical diagnosis.
Advantages and disadvantages:
The benefits of AI in dermatology diagnosis include increased efficiency in diagnosing and monitoring skin conditions, thereby mitigating the effects of specialist shortages. The technology could lead to earlier detection of melanoma, which could significantly improve patient outcomes.
Disadvantages include costs associated with deploying such technology, potential errors in diagnostic processes without human oversight, and deprioritization of developing human expertise over the long term. Privacy issues also arise when collecting and storing medical images.
