Abstract
BACKGROUND & OBJECTIVE: Vulvar squamous cell carcinoma (VSCC) accounts for about 80%-90% of female vulvar malignant tumors, but the etiology is still unclear. This study was to identify genetic alteration in VSCC by comparative genomic hybridization (CGH). METHODS: The genomic imbalance, that is, gains or losses of chromosomes, in 21 cases of vulvar squamous cell carcinoma was detected by CGH. RESULTS: The common chromosomal alterations in VSCC included gains of chromosomes 3q, 8q and 12q, and losses of chromosomes 4p and 3p. CONCLUSIONS: There are multiple chromosomal aberrations in VSCC. The amplification of the tumor suppressor genes and loss of the oncogenes on these regions may be involved in the development and progression of VSCC.
