Background: The incidence of microsatellite alterations at the endemic betel quid chewing area and its association with the survival of patients with oral cavity squamous cell carcinoma (OCSCC) is not clear. Here we studied their possible relationship.
Methods: Subjects were 135 patients with histological confirmed OCSCC. From these patients we obtained their cancerous tissues, corresponding surgical margins, and peripheral blood samples. From these specimens, we analyzed the microsatellite alterations base on 10 oligonucleotide markers. Specifically, specimens were assessed by automatic fragment analysis following amplification by polymerase chain reactions.Results: Of these specimens, 45 (33.3%) showed microsatellite instability (MSI) and 78 (57.8%) showed loss of heterozygosity (LOH) for at least one marker. Using Kaplan-Meier’s analysis method, microsatellite alterations of patients did not associate with their disease-specific survival. However, the presence of MSI in surgical margins of the cancer increased the risk of local recurrence (odds ratio: 7.49; 95% confidence interval: 3.34 ~ 16.80; P < 0.001).Conclusion: The prognosis of OCSCC patients was not associated with microsatellite alterations in region where betel quid chewing is prevalent. However, genomic examination of surgical margin can possibly find out OCSCC patients who are prone to develop local recurrence.
