Abstract
BACKGROUND: Chinese nasopharyngeal carcinoma (NPC) specimens were analyzed by microsatellite allelotyping to evaluate their usefulness as biomarkers for cancer detection. MATERIALS AND METHODS: A panel of eight microsatellite markers localized to chromosomes 3p, 6p, 9p, I1q and 14q were used to study 47 specimens. RESULTS: A moderately low loss of heterozygosity (LOH) frequency (8% to 35%) was observed; 23 (49%) specimens showed LOH with at least one marker while microsatellite instability (MSI) was detected in 10 specimens (21%). CONCLUSION: Poor survival was significantly associated with LOH detected by a chromosome 3 marker. Interestingly, tumors with multiple genetic alterations were significanty associated with earlier staging
