Microsatellite DNA alterations are an integral part of neoplastic progression and are valuable as clonal markers for the detection of human cancers 1–3. Moreover, recent evidence suggests that senescent tumor cells may release DNA into the circulation, which is subsequently carried by and therefore enriched in the serum and plasma 4,5. We tested 21 patients with primary head and neck squamous cell carcinoma (HNSCC) by polymerase chain reaction (PCR)–based microsatellite analysis of DNA from lymphocytes and paired serum samples. Patients were scored for alterations as defined by the presence of new alleles (shifts) or loss of heterozygosity (LOH) in serum at each of 12 markers and then compared with primary tumor DNA.

Six out of 21 patients (29%) were found to have one or more microsatellite alterations in serum precisely matching those in the primary tumors. All six patients had advanced disease (stage III or IV); five of these patients had nodal metastases, three later developed distant metastases, and four died of disease.

Microsatellite analysis of serum represents a novel method for the detection of circulating tumor cell DNA. If these results are confirmed in larger studies, microsatellite markers may be useful in assessing tumor burden in cancer patients.

Squamous cell carcinoma of the oral cavity (SCCOC) is one of the most prevalent tumors of the head and neck region. Despite improvements in treatment, the survival of patients with SCCOC has not significantly improved over the past several decades.

Most frequently, treatment failure takes the form of local and regional recurrences, but as disease control in these areas improves, SCCOC treatment failures more commonly occur as distant metastasis. This book summarizes the current status of investigations into SCCOC metastases and potential of these studies to positively impact clinical management of SCCOC in the future.
