Instead of relying on routine surgical biopsies, dermatologists may soon be sharing, reviewing and diagnosing noninvasive digital images of skin cells via the Internet, using Lucid Inc.’s VivaNet telemedicine server and its VivaScope confocal imagers.

Rochester-based Lucid has developed innovative cellular imaging technology and is now leveraging the Internet to securely deliver accurate, real-time cellular resolution images to medical professionals.

Anytime, Anywhere Collaboration

The company’s VivaScopeconfocal microscopes can image living tissue with cellular resolution and – importantly for patients – without the need to excise tissue. The VivaNet server is intended to provide fast, accurate and secure storage, retrieval and transfer of the images across the Internet. The technology is expected to facilitate anytime, anywhere professional collaboration and consultation among medical practitioners and pathologists in forming a clinical judgment for a variety of skin conditions, including skin cancer and other dermatologic conditions.

Just as MRI and CT scans have largely eliminated the need for routine exploratory surgery, in-vivo reflectance confocal microscopy may one day eliminate the need for routine invasive skin biopsy.

A typical VivaScope imaging session produces two types of images of the patient’s skin: dermatoscopic-quality, full-color macroscopic pictures and microscopic, cellular resolution images. Once all of the images for a session are completed, the images and patient-related data are transferred for storage to the secure VivaNet server, where they are immediately available for retrieval by and transfer to other authorized practitioners for their review and collaboration.

VivaNet is an Internet-based application that enables the transfer of VivaScope digital images between practitioners and pathologists for rapid review of confocal images. It conforms to DICOM (Digital Imaging and Communications in Medicine), an internationally accepted standard for the secure storage, retrieval and transfer of medical images, and it complies with federal HIPAA requirements for privacy and integrity of medical data.
 

Answers in Minutes, Not Days

The plan at Lucid is for VivaNet to ultimately make VivaScope images available for review by other dermatologists and pathologists in minutes, not days – thus enabling rapid, real-time professional collaboration. The ultimate goal is that practitioners will rapidly receive a pathologic interpretation of confocal images from a VivaScope session, potentially assisting the practitioner in arriving at a clinical judgment while the patient is still in the doctor’s office.

Lucid received a $1.9 million, 3-year grant from the National Institute of Health’s National Cancer Institute to perform a large clinical study to evaluate the efficacy of its VivaScope in-vivo confocal microscopy technology for the diagnosis of pigmented lesions. The study, which is being conducted at five sites, will involve approximately 600 patients with suspicious pigmented lesions.

An earlier pilot study of the accuracy of confocal imaging for diagnosis lesions suspected to be melanoma showed improved diagnostic accuracy for melanocytic lesions that are difficult to diagnose. This improvement could translate into lives saved. The American Cancer Society estimated that in 2007, 59,940 new cases of invasive melanoma will be diagnosed in the United States, and that 8,110 deaths will occur due to the disease. According to Cancer Facts and Figures 2007, if melanoma is diagnosed and removed while the tumor is localized, the 5-year survival rate is 99 percent; however, if the lesion has metastasized to a regional site, the five-year survival rate drops to 65 percent, and if it has metastasized to a distant site, the rate drops to 15 percent.

With the introduction of VivaNet to the dermatology community, Lucid believes that the combination of its patented VivaScope and VivaNet technologies will ultimately enter routine clinical use.
