A 3q+ marker chromosome in EBV‐carrying nasopharyngeal carcinomas

Abstract
The malignant epithelial cells of two anaplastic EBV‐carrying nasopharyngeal carcinomas (NPC) were investigated cytogenetically by Giemsa banding technique. Both tumors had a similar 3q+ marker chromosome with an involvement of band q25, either a dupliction of the region q25–q27, or insertion of an unidentified segment at band q25.
