Peter Zedler, and his team are currently enrolling participants in a clinical research study to evaluate the effectiveness of a new vaccine that would treat women who have HPV and the precancerous lesions associated with it.
Recent pilot studies have shown that simple, commercially available optical devices have the potential to improve the detection of early precancerous lesions compared to visual inspection.
This study clearly shows that HPV screening is more sensitive to picking up precancerous lesions than the other tests," says the study's coauthor Rengaswamy Sankaranarayanan of the World Health Organization's International Agency for Research on Cancer in Lyon, France.
