| pubmed-article:20373331 | pubmed:abstractText | Head and neck squamous cell carcinomas develop in preneoplastic mucosal fields that can extend over several centimeters in diameter. Most of these fields are microscopically recognized as dysplasias. These fields are often not adequately treated and might cause local relapse. Previous investigations demonstrated that mouthwash therapy with oncolytic adenoviruses appears to be a good option for the treatment of these fields, although, at present, with limited efficacy. | lld:pubmed |
