In this study, we investigated CNAs of 20 gastric CISs (Vienna category 4.2) and 20 adenomas including seven low-grade adenomas (LGA; Vienna category 3) and 13 high-grade adenomas (HGA; Vienna category 4.1), using oligonucleotide-based array CGH.
29 salivary tumor samples: Cystadenolymphoma-warthin (15) and adenoma polymorphum (14) located in the parotid (27) and submandibular gland (2) were collected and CGH was performed.
